Subacute infectious endocarditis-associated membranoproliferative glomerular nephritis: A Case Report and Review

Published on: 17th August, 2017

OCLC Number/Unique Identifier: 7286354493

We experienced a case of membranoproliferative glomerulonephritis (MPGN) caused by subacute infectious endocarditis (SIE). A 57-year-old male farmer complained of fatigue, lack of appetite and gross haematuria for a month; he had no cough, chest pain, or exertion dyspnea. After admission, lab tests showed mild proteinuria(1.04g/d) and heavy dysmorphic red blood cells(RBC) (543/HP), with serum creatinine(Scr) slightly elevated(1.46mg/dl) and anemia(hemoglobin Hb 85g/L). A renal biopsy revealed MPGN lesion with 16.6% cellular crescents. The echocardiogram test revealed mitra valve prolapse with perforation of the anterior lobe, vegetation, and severe regurgitation. He was diagnosed as SIE induced MPGN. Then he underwent mitral valve replacement after systemic antibiotic treatment without immunosuppressive agents. Follow-up showed that he dramatically regained normal kidney function in total 1 year after the operation. Thus, antibiotic administration and valve replacement may be efficient enough for some of SIE induced MPGN. We did a brief review of the literature on SIE induced MPGN, which was sometimes misdiagnosed due to its silent characteristics; some SIE patients may initially have other organs involved.

Value of electrocardiographic T wave inversion in lead aVL in prediction of Mid Left Anterior Descending Stenosis in patients with stable Coronary Artery disease

Published on: 18th August, 2017

OCLC Number/Unique Identifier: 7286426390

Background: The electrocardiogram (ECG) is a simple and noninvasive bedside diagnostic tool with a well-established role in the diagnosis of coronary artery disease (CAD). We aimed to study the diagnostic value of electrocardiographic ST-T wave changes in lead aVL in prediction of site of coronary artery stenosis in patients with chronic stable angina. Patients and Methods: study was conducted on 156 patients referred for invasive coronary angiography with history of stable CAD as proved by non- invasive tests, 12 lead ECG was recorded and fully interpreted with more focus on T wave direction in aVL lead. T waves in aVL were categorized into one of three groups: upright, flat or inverted. Results: regarding T wave in lead aVL, inverted T wave was reported in 71(45.5%) patients, 58 (37.2%) patients were with upright T wave in lead aVL and 27(17.3%) patients were with flat T wave in lead aVL, and we found that inverted T wave in lead aVL was most evident in 56(73.7%) patients with mid LAD with (highest κ value equal to 0.550[moderate agreement], and p value<0.001. Conclusions: This study confirmed the diagnostic value of T wave inversion in lead aVL in prediction of mid left anterior descending artery lesions in patients with stable coronary artery disease.

Non-hemodynamic factors associated to the risk of developing hypertensive cardiopathy

Published on: 20th September, 2017

OCLC Number/Unique Identifier: 7286431107

Introduction: Hypertensive cardiopathy is the target organ lesion caused by arterial hypertension (HTN) that exhibits the highest morbidity and mortality rates. Although the importance of hemodynamic overload exerted by HTN on the onset of cardiopathy is well established, several non-hemodynamic factors may contribute significantly to its development. Objective: To evaluate the influence of different non-hemodynamic risk factors in the development of hypertensive cardiopathy. Methods: A prospective cohort study was carried out in hypertensive patients assisted at the specialized arterial hypertension physicians’ office of the “Carlos Manuel de Céspedes” Specialty Policlinic attached to the General University Hospital, Bayamo Municipality, Granma Province, Cuba from January 5, 2006 to December 31, 2015. The study included 18-to-55-year-old hypertensive patients with a stage 1 arterial hypertension diagnosis for less than a year1. Results: The multivariate analysis showed a significant and independent relation among the majority of the factors studied and the risk of developing cardiopathy. The major factor was C-reactive protein (HR: 5.020; IC 95%: 3.383-7,448; p<0.005) followed by microalbuminuria (HR: 2.649; IC 95%: 1.932-3.631; p<0.005). The area under the model ROC curve was 0.887 (p<0,005). Conclusions: The results showed that it is possible to estimate the risk of developing hypertensive cardiopathy with the application of the regression model to major risk factors.

Numerical Simulation of Thrombotic Occlusion in Tortuous Arterioles

Published on: 6th December, 2017

OCLC Number/Unique Identifier: 7666340975

Tortuous microvessels alter blood flow and stimulate thrombosis but the physical mechanisms are poorly understood. Both tortuous microvessels and abnormally large platelets are seen in diabetic patients. Thus, the objective of this study was to determine the physical effects of arteriole tortuosity and platelet size on the microscale processes of thrombotic occlusion in microvessels. A new lattice-Boltzmann method-based discrete element model was developed to simulate the fluid flow field with fluid-platelet coupling, platelet interactions, thrombus formation, and thrombotic occlusion in tortuous arterioles. Our results show that vessel tortuosity creates high shear stress zones that activate platelets and stimulate thrombus formation. The growth rate depends on the level of tortuosity and the pressure and flow boundary conditions. Once thrombi began to form, platelet collisions with thrombi and subsequent activations were more important than tortuosity level. Thrombus growth narrowed the channel and reduced the flow rate. Larger platelet size leads to quicker decrease of flow rate due to larger thrombi that occluded the arteriole. This study elucidated the important roles that tortuosity and platelet size play in thrombus formation and occlusion in arterioles.

Design and validation of an Index to predict the development of Hypertensive Cardiopathy

Published on: 16th February, 2018

OCLC Number/Unique Identifier: 7347023220

Introduction: The high morbidity and mortality by hypertensive cardiopathy demand the construction and validation of tools to stratify the risk of developing this condition. Objective: To design and validate an index, based on risk factors, that permits to predict the development of hypertensive cardiopathy in patients with a diagnosis of essential arterial hypertension. Methods: A prospective cohort study was done in hypertensive patients assisted at the specialized arterial hypertension physicians’ office of the “Carlos Manuel de Céspedes” Specialty Policlinic attached to the General University Hospital, Bayamo Municipality, Granma Province, Cuba from January 1st, 2010 to December 31, 2016. Internal and external validity and the internal consistency of the index were determined. Results: The index sensitivity was of 97, 20 (IC: 93, 93-94.09) and specificity of 65, 38 (IC: 76, 25-76, 20). Both the index discriminative capacity (area under the ROC curve= 0,944; interval of confidence: 0.932-0.956; p<0.0005) and calibration (p=0.751) were adequate. Conclusions: The present study proposes an index to predict the risk of developing hypertensive cardiopathy, with adequate discriminative capacity and calibration (external validity). The index can be used as a tool of clinical and epidemiological surveillance since it permits to identify subjects with greater probability of developing the condition and to stratify the risk.

Assessment of risk factors and MACE rate among occluded and non-occluded NSTEMI patients undergoing coronary artery angiography: A retrospective cross-sectional study in Multan, Pakistan

Published on: 30th May, 2018

OCLC Number/Unique Identifier: 7795966987

Objectives: The prime focus of the present study was to evaluate the most occluded coronary artery (OCA) among non-ST elevated myocardial infarction (NSTEMI) patients, and risk factors associated with occluded and non-occluded NSTEMI. Also, major adverse cardiovascular event (MACE) were evaluated among patients during index hospitalization. Methods: A retrospective, cross-sectional study was conducted in Multan Institute of Cardiology, Pakistan between 1st February, 2017, and 31st September, 2017. The data were collected from medical records of the outpatients and inpatients who were index hospitalized. Data were analyzed by using Statistical Packages for Social Sciences (IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp.) And Microsoft Excel (MS Office 2010). Results: Among 624 patients, angiographic findings revealed that 63.9% were suffering from non-occlusive NSTEMI while 36.1% of the patients had occluded NSTEMI. In occluded NSTEMI patients, 30.3% were having single vessel occlusion while 5.8% were having multi-vessel occlusion. Also, 49.8% were having occlusion of right coronary artery (CA) while 44% were having occluded left anterior descending (LAD) artery. Multivariate analysis revealed that age (p=0.001) and left ventricular ejection fraction (LVEF) (p=0.001) had a statistically significant association. The incidence of MACE was high among non-OCA patients as compared to OCA patients but no statistically significant association was found (p=0.44). Conclusions: Angiography confirmed that most of the NSTEMI patients had OCA. But the MACE rate was not significantly differ among OCA and non-OCA patients. The risk factors associated with OCA were low LVEF and age.

Cardiovascular damage during lupus in black African subjects

Published on: 16th July, 2018

OCLC Number/Unique Identifier: 7795917457

Introduction: Systemic lupus is a disseminated inflammation of the conjunctive tissue. Cardiovascular lesions are the first cause of morbidity and mortality in the course of that disease. These lesions are prevalent in 30 to 62% of cases, depending on whether the diagnostic tool is clinical, echocardiographic, or autopsic. Any part of the heart can be affected, yielding manifestations of pericarditis, endocarditis, coronary heart disease, conduction disorders, and rarely myocarditis. Objective: Describe cardiac manifestations during the follow up of patients diagnosed with systemic lupus. Patients and Methods: We conducted a transversal descriptive study over a period of 27 months, in the departments of Internal Medicine, Dermatology, and Cardiology of Yalgado Ouedraogo University Hospital of Ouagadougou. All patients diagnosed with systemic lupus according to the American College of Rheumatology criteria, and having done an EKG, a Holter EKG, or a transthoracic echocardiography, were included in the study. Data were collected from inpatient medical records, outpatient follow up registry and booklets. Results: Cardiovascular lesions were prevalent in 7 cases (43.75%) out of 16 patients diagnosed with systemic lupus. Mean age of patients was 36 years, with extremes of 23 and 51 years. Only female patients were affected in our study. Cardiac manifestations were mainly benign pericarditis, heart failure, and conduction disorders. Conclusions: Cardiovascular manifestations are frequent during the course of systemic lupus, and occur after few years of disease progression. Transthoracic echocardiography and EKG remain useful non-invasive explorations for the assessment of cardiovascular lesions, despite minor shortcomings.

Use of Rivaroxaban and Apixaban, Two Non-Vitamin K Antagonist Oral Anticoagulants (NOACs), in Renally Impaired Patients - the limits of our knowledge

Published on: 11th October, 2018

OCLC Number/Unique Identifier: 7893782754

Patients with chronic kidney disease are at increased risk of thromboembolic complications and are therefore often managed with anticoagulation therapy [1]. While these patients are traditionally treated with Vitamin K antagonists (VKAs), the Non-Vitamin K antagonist oral anticoagulants (NOACs), such as rivaroxaban and apixaban are being used with increasing frequency. Relatively new to the anticoagulant treatment arsenal, both compounds are direct Factor Xa inhibitors and represent an alternative to traditional VKA treatments, such as warfarin. However, because these compounds are at least partially renally eliminated, achieving safe and effective anticoagulation in this vulnerable population has proven to be a challenge [2,3]. With limited published data, there is often uncertainty surrounding which of the NOACs can be safely used.

An observational study of the occurrence of anxiety, depression and self-reported quality of life 2 years after myocardial infarction

Published on: 17th October, 2018

OCLC Number/Unique Identifier: 7893782705

Background: Patients with myocardial infarction (MI) often experience anxiety, depression and poor quality of life (QoL) compared with a normative population. Mood disturbances and QoL have been extensively investigated, but only a few studies have examined the long-term effects of MI on these complex phenomena. Aims: To examine the levels and associated predictors of anxiety, depression, and QoL in patients 2 years after MI. Methods: This was a single center, observational study of patients with MI (n=377, 22% women, median age 66 years). Two years after MI (2012-2014), the patients were asked to answer the Hospital Anxiety and Depression Scale (HADS) and EuroQol 5-dimension (EQ-5D-3L) questionnaires. Results: Most patients experienced neither anxiety (87%, 95% confidence interval [CI]: 83-90%) nor depression (94%, 95% CI: 92-97%) 2 years post-MI. Elderly patients experienced more depression than younger patients (p=0.003) and women had higher anxiety levels than men (p=0.009). Most patients had “no problems” with any of the EQ-5D-3L dimensions (72-98%), but 48% (95% CI: 43%-53%) self-reported at least “some problems” with pain/discomfort. In a multiple logistic regression model (EQ-5D-3L) higher age (p<0.001) and female sex (p<0.001) were associated with more pain/discomfort. Female sex (p=0.047) and prior MI (p=0.038) were associated with anxiety/depression. History of heart failure was associated with worse mobility (p=0.005) and problems with usual activities (p=0.006). The median total health status of the patients (EQ-VAS) was 78 (95% CI: 75-80)

Diagnostic accuracy of TIMI versus GRACE score for prediction of death in patients presenting with Acute Non-ST Elevation Myocardial Infarction (NSTEMI)

Published on: 22nd February, 2019

OCLC Number/Unique Identifier: 8022255638

Background: Acute Coronary Syndrome describes a spectrum of disease ranging from unstable angina through non-ST-Elevation Myocardial Infarction (NSTEMI) to ST-Elevation Myocardial Infarction (STEMI). Early death in NSTEMI is usually due to an arrhythmia. Patients should be admitted immediately to hospital, preferably to a cardiac care unit because there is a significant risk of death. Objective: To compare the diagnostic accuracy of TIMI versus GRACE for prediction of death in patients presenting with Acute Non-ST elevation Myocardial Infarction. Material & Methods: This present cross sectional study was conducted at Department of Cardiology, CPEIC, Multan. All patients assessed according to given scores in the two scoring system i.e. TIMI risk score and GRACE score. Then patients were labeled as high or low risk for death. Data was collected by using pre-designed proforma. 2x2 tables were generated to measure the sensitivity, specificity, positive predictive value, negative Predictive value and diagnostic accuracy of TMI Risk score and GRACE Score for prediction of death in NSTEMI patients. Results: In our study the mean age of the patients was 55.73±9.78 years. The male to female ratio of the patients was 1.6:1. The diabetes as risk factor was found in 145(39%) patients, smoking as risk factor was found in 53(14.2%) patients and hypertension as risk factor was found in 174(46.8%) patients. the sensitivity of TIMI risk was 97.7% with specificity of 92.93% and the diagnostic accuracy was 95.16%, similarly the sensitivity of GRACE risk was 100% with specificity of 95.96% and the diagnostic accuracy was 97.85%. Conclusion: Our study results concluded that both the TIMI risk and GRACE risk are good predictor of death in patients presenting with Acute Non-ST elevation Myocardial Infarction with higher sensitivity and diagnostic accuracy. However the GRACE risk showed more accurate results as compared to TIMI risk.

Is secondary prevention information before discharge adequate after percutaneous coronary intervention?

Published on: 8th May, 2019

OCLC Number/Unique Identifier: 8163873247

Introduction: Implementation of prevention strategies for patients with coronary artery disease (CAD) is essential, but many fall short of reaching their goals. Patients often perceive themselves as healthy and are less motivated to change lifestyle. To obtain better results patients need repeated information, preferably with motivational and person-centered approaches. Aims: To investigate whether health care providers inform CAD patients about risk factors and lifestyle changes at a percutaneous coronary intervention unit. Also to investigate whether the information given at discharge included secondary prevention management and if motivational and person-centered approaches were used. Methods: This is a descriptive, observational study that includes both a qualitative and quantitative design. Physicians and nurses working at a percutaneous coronary intervention (PCI) unit and physicians at a coronary care unit (CCU) participated. A staff nurse observed and noted what information the patients received at the PCI unit. At the CCU, observations regarding secondary prevention strategies during the discharge counselling were performed. Results: There were 50 observations made at the PCI unit. The information mainly consisted of tobacco consumption, physical activity and diet. During the 31 discharge counselling sessions the diagnosis, interventional procedure and medical treatment were frequently included. Most patients received little or no person-centered or motivational counselling. Conclusion: Nearly all patients at the PCI unit received information about the consequence of tobacco consumption, and more than half about the beneficial effects of physical activity. In contrast, the counselling at discharge need to focus more on behavioral changes and a motivational and person-centered approach.

Single-centre real world experience of the Mynx Femoral closure device in patients undergoing percutaneous coronary intervention

Published on: 4th June, 2019

OCLC Number/Unique Identifier: 8165159464

Background: Vascular closure devices are routinely used following femoral artery access to perform percutaneous coronary interventions (PCI). A number of devices are available on the market. We have reported previously on our experience of the Mynx device following diagnostic coronary angiography. Aims: To assess the success and complication rates of the Mynx device used in all-comers in the context of PCI within a single cardiac centre. Methods: Retrospective analysis of data available for patients who underwent PCI via the femoral route and received a Mynx device at a single tertiary centre. Results: The device was used to achieve haemostasis in 113 patients following PCI. In all cases weight-adjusted Heparin as well as dual antiplatelet therapy (Aspirin and Clopidogrel/ Ticagrelor) was administered as per PCI protocol. The device was successfully deployed in 111 cases (98.2%). The were 2 cases of device failure, one due to operator error and the other due to Mynx grip balloon bursting during device deployment. In 15 cases (13.2%; 9 male and 6 female) there were reports of small haematomas (<2cm) or oozing resulting in application of manual pressure or Femstop (St. Jude). A further patient required ultrasound-guided compression of the artery due to a large retroperitoneal bleed resulting from access complications. A larger proportion of the cases with complications were done as PPCI (44% vs 33%). The group with complications had higher systolic BP (140mmHg vs 128mmHg; P<0.05) and MABP (97mmHg vs 75mmHg; P<0.05) as compared with the group without any complications. Conclusion: The Mynx closure device is safe and easy to use in the context of PCI, in both the elective and emergency (PPCI) settings. Complication rates, predominately minor, can be minimised in experienced hands.

Impact of the Israeli attacks at 2014 on incidence of STEMI in Gaza

Published on: 7th June, 2019

OCLC Number/Unique Identifier: 8165496914

For 51 days, Gaza was pummeled down by the Israeli military in a war known as Operation Protective Edge. During the 50 days (7-7-204 to 28-8-2014) of the Israeli campaign, 2104 Palestinians were killed, including 253 women (12%) and 495 children (24%). According to the UN, at least 69% of Palestinians killed were civilians. It is estimated that 10,224 Palestinians, including 3,106 children (30%) and 1,970 women (19%) were injured. Preliminary estimates indicate that up to 1,000 of the children injured will have a permanent disability and up to 1,500 orphaned children will need sustained support from the child protection and welfare sectors, 17,200 homes destroyed or severely damaged, 58 hospitals and clinics damaged [1]. Major stressful events are well documented to increase the incidence of acute cardiac events [2]. Cardiovascular complications more than doubled during the FIFA World Cup games of 2006 [3]. After the September 11 terrorist attacks, significantly more patients presented with acute myocardial infarction to the hospitals in Brooklyn [4] and New Jersey [5]. We were able to examine the effects of the Isreli attacks on acute STEMI presentations in Gaza city.

C-reactive protein is associated with ventricular repolarization dispersion among patients with metabolic syndrome

Published on: 27th June, 2019

OCLC Number/Unique Identifier: 8192802745

Background: An increasing body of evidence indicates that inflammatory activation profoundly impacts the electrophysiological properties of cardiomyocytes. A marker of systemic inflammation such as C-reactive protein(CRP), is associated with all parameters of the Mtabolic syndrome(MetS) and that may result in adverse cardiac events via multiple effects, ultimately resulting in a prolongation of Action Potential duration (APD), and thereby of the QTC (QT corrected) interval on ECG. Objective: We sought to investigate the influence of CRP levels on the prevalence of prolonged QT-dispersion and prolonged Tpeak-Tend –dispersion in the patients with MetS. Methods: We conducted a multicenter observational cross-sectional study. The study population consisted of 200 patients with MetS, stratified in two groups:103 participants (50 females and 53 males) with level of CRP>3mg/l, and 97 participants (47 females and 50 males) with level of CRP<3mg/l), who attended outpatient visits at general cardiology Health Care Clinics during 1 calendar year. For the analysis of the ECG, we performed a manual measurement of the values using a digital caliper with measuring range of 0-150 mm, 0.01 mm resolution, and 0-100 ± 0.02 mm accuracy. QT interval dispersion was obtained by the difference between the maximum and the minimum QT intervals found in the 12-lead electrocardiogram. The Tpeak-Tend interval was obtained from the difference between QT interval and QTpeak interval. Results: Prolonged QTC. dispersion, was found in 51.4% of participants with level of CRP>3mg/l and in 32.9% of with level of CRP<3mg/l, the differences were statistically significant. (p=0.004). The results showed that 51.4% participants with level of CRP>3mg/l had a prolonged Tpeak-Tend interval, and 32.9% of participants with level of CRP<3mg/l had prolonged Tpeak-Tend interval. Difference were statistically significant.( p=0.04). There were significant association of increased levels of CRP and QTC-dispersion (OR = 2.486, 95% CI 1.389-4.446).There were significant association of increased levels of CRP with Tpeak-Tend Dispersion (OR=2.239,95%CI 1.262-3.976). Prolonged QTC max. Interval OR=2.236,%CI 1.246-4.014),Prolonged Tp-Te-interval. (OR=2.367, 95%CI 1.327-4.222), also there were significant association of increased levels of CRP with BMI. (OR=1.154, 95%CI 1.095-1.227) and significant association of increased levels of CRP with presence of uncontrolled glicemia.(OR=1.779, 95%CI 1.014-3.12). Conclusion: We think we proved the hypothesis that patients with MetS and high level of CRP have higher prevalence of QT- dispersion and Tpeak-Tend dispersion than patients with MetS and lower level of CRP. These findings have both epidemiological and clinical relevance, also these findings might lend further insight into potential mechanisms by which MetS is associated with adverse cardiac events.

Preclinical stiff heart is a marker of cardiovascular morbimortality in apparently healthy population

Published on: 31st July, 2019

OCLC Number/Unique Identifier: 8192795566

Background: The prognostic significance of impaired left ventricular (LV) relaxation and increased LV stiffness as precursor of heart failure with preserved ejection fraction and death is still largely unknown in apparently healthy subjects. Methods: We constituted a cohort of 353 patients with normal ejection fraction (>45%) and no significant heart disease, based on a total of 3,575 consecutive left-sided heart catheterizations performed. We measured peak negative first derivative of LV pressure (-dP/dt) and operating chamber stiffness (Κ) using a validated equation. Patients were categorized as having: 1) normal diastolic function, 2) isolated relaxation abnormalities (-dP/dt > 1860mm Hg/sec and K <0.025mm Hg/ml), or 3) predominant stiff heart (K ≥0.025mm Hg/ml). Results: During a follow-up of at least 5 years, the incidence of the primary composite endpoint (death, major arterial event, heart failure, and arrhythmia) was 23.2% (82 patients). Compared to isolated relaxation abnormalities, predominant stiff heart showed stronger prognostic significance for all events (p=0.002), namely heart failure (HR, 2.9; p=0.0499), cardiac death (HR, 5.8; p=0.03), and heart failure and cardiac death combined (HR, 3.7; p=0.003). Conclusion: In this apparently healthy population referred to our center for cardiac catheterization, the prevalence of diastolic dysfunction was very high. Moreover, predominant stiff heart was a better predictor of cardiovascular outcomes than isolated relaxation abnormalities.

P wave dispersion in patients with premenstrual dysphoric disorder

Published on: 31st July, 2019

OCLC Number/Unique Identifier: 8192811430

Background: Growing evidence has revealed that fear and anxiety related situations could affect cardiac parameters. P wave dispersion (Pd) is an important index. In the present study, we aimed to evaluate Pd values in patients with premenstrual dysphoric disorder. Methods: The study was composed of twenty-five female patients with premenstrual dysphoric disorder and same number of healthy controls. Pd, Pmin and Pmax values were determined by electrocardiogram (ECG) in the subjects. Results: It was found that patients with premenstrual dysphoric disorder had considerably higher Pmax and Pmin values compared to those of healthy subjects. Pd was also significantly higher in patients with premenstrual dysphoric disorders than that of healthy subjects. Conclusion: Study suggests that patients with premenstrual dysphoric disorder seems to have increased Pd, as can be seen in anxiety and fear related clinical conditions, considering that this group of patients have an increased trend to cardiac abnormalities, particularly cardiac arrythmias. To access strong conclusion, it is required novel studies with larger samples.

Role of novel cardiac biomarkers for the diagnosis, risk stratification, and prognostication among patients with heart failure

Published on: 22nd August, 2019

Background: Current guidelines for diagnosis and management of heart failure (HF) rely on clinical findings and natriuretic peptide values, but evidence suggests that recently identified cardiac biomarkers may aid in early detection of HF and improve risk stratification. The aim of this study was to assess the diagnostic and prognostic utility of multiple biomarkers in patients with HF and left ventricular systolic dysfunction (LVSD). Methods: High-sensitivity cardiac troponin I (cTnI), N-terminal pro b-type natriuretic peptide (NT-proBNP), interleukin-6 (IL-6), endothelin-1 (ET-1), pro-matrix metalloproteinase-9 (pMMP-9), and tumor necrosis factor-alpha (TNF-α) were measured using single-molecule counting technology in 200 patients with varying stages of HF. Plasma detection with cross-sectional associations of biomarkers across all HF stages, and advanced-therapy and transplant-free survival were assessed using multivariate analysis and Cox regression analyses, respectively. Results: NTproBNP, pMMP-9, IL-6 were elevated in early, asymptomatic stages of HF, and increased with HF severity. Higher circulating levels of combined IL-6, NTproBNP, and cTnI predicted significantly worse survival at 1500-day follow-up. Cox regression analysis adjusted for ACC/AHA HF stages demonstrated that a higher concentration of IL-6 and cTnI conferred greater risks in terms of time to death, implantation of left ventricular assist device (LVAD), or heart transplantation. Conclusion: Biomarkers of inflammation, LV remodeling, and myocardial injury were elevated in HF and increased with HF severity. Patients had a significantly higher risk of serious cardiac events if multiple biomarkers were elevated. These findings support measuring NTproBNP, cTnI and IL-6 among patients with HF and LVSD for diagnostic and prognostic purposes.

Anomalies of coronary artery origin: About two cases

Published on: 13th September, 2019

OCLC Number/Unique Identifier: 8270707766

Anomalies of coronary artery origin are congenital malformations characterized by the abnormal birth of a coronary artery from the controlateral coronary aortic sinus (birth of the left coronary artery from the right sinus or birth of the right coronary artery from the left sinus). The artery concerned has an abnormal initial path between the aorta and the pulmonary artery; this segment is most often intramural, in the aortic wall. They are rare with a prevalence (0.1% to 0.3% of the population). They pose a high risk of sudden stress death related to exercise myocardial ischemia. The most common mode of discovery is aborted sudden death, but sometimes fortuitously. The contribution of multi-round CT is described for the positive diagnosis of these anatomical variations, sometimes delicate in coronary angiography, but also for the distinction between “benign” and “malignant” forms, potentially responsible for myocardial ischemia. Treatment is usually surgical in symptomatic forms. We report the cases of two patients with coronary connection abnormalities discovered in adulthood.

Novel paclitaxel-coated balloon angioplasty via single retrograde popliteal access for challenging superficial femoral artery and iliac artery lesions?

Published on: 24th September, 2019

OCLC Number/Unique Identifier: 8261371866

Objectives: We report our results regarding the use of BioPath™ paclitaxel-coated balloon catheters for superficial or distal external iliac artery revascularization via single retrograde popliteal access. Methods: We included 105 prospective consecutive patients. Single retrograde popliteal access was achieved under ultrasound guidance with the patients laid prone. An over-the-wire atherectomy system was used if risk of distal embolization was high due to plaque intensity of the target lesion. A 4 to 7 mm-diameter BioPath™ 035 balloon catheter was used for all lesions. Follow-up at 6th month included doppler ultrasound examination for patency. Results: Seventy-two patients (68.6%) had total SFA occlusion and 41 patients (39%) had concomitant external iliac artery involvement, out of whom 31 (29.5%) had total occlusion. Procedural success 90.5% for superficial femoral artery and 85.3% for external iliac artery. One-year patency rates in SFA and EIA were 84.8% and 80.4%, respectively Conclusion: Single retrograde popliteal access and drug-coated balloon angioplasty may offer a useful alternative to known modalities in treatment of challenging superficial femoral artery and concomitant iliac artery lesions
