Faecal Transplant Therapy: A Promising Treatment Modality for Cardiovascular Diseases

Published on: 28th August, 2023

Cardiovascular diseases (CVD) are considered as “lifestyle” diseases and so far “No unified procedure” or medicines are effective in the management of this group of diseases. Researchers and clinicians have indicated that no safe therapeutic window is available in therapeutics at present. Recent research showed that gut microbiota are effective in managing lifestyle diseases therefore we introduced the influence of gut microbiota in the prognosis of the CVDs. Faecal transplant therapy(FMT) has been anticipated to treat many diseases similar to recurrent bacterial Clostridioides difficile infection which has been used worldwide. Recently, FMT was tried on an animal model to treat CVDs, and recent human trials that were tried to manage CVDs in humans by FMT showed encouraging results. The mechanism of action of transplanted bacteria to manage CVDs in the human population is also discussed. In-depth knowledge on the pros and cons of FMT will pave the way to standardize the procedure once the lacuna existing at present in treating CVDs, is paved, this technology will be useful for the masses.

Association of Periprocedural Haemoglobin Reduction and Myocardial Injury in Patients with Unstable Angina Undergoing Percutaneous Coronary Intervention

Published on: 23rd October, 2023

Background: Patients undergoing percutaneous coronary intervention are at risk of different complications such as periprocedural bleeding and acute hemoglobin reduction that can lead to myocardial injury. Blood loss through the catheter during the procedure and through puncture site haematoma causes periprocedural acute haemoglobin drop.Objectives: To find out the association between acute haemoglobin reduction and myocardial injury after PCI in patients with unstable angina. Methods: This prospective observational study was conducted at the National Institute of Cardiovascular Diseases (NICVD) for one year of time. A total of 130 patients were enrolled based on inclusion and exclusion criteria during the study period. Haemoglobin and troponin-I were measured before and after PCI within 24 to 48 hours of the procedure. On the basis of post-procedural acute haemoglobin level, the study population was categorized into two groups: Group I patients with normal haemoglobin levels and Group II patients with significant acute haemoglobin reduction (≥ 1 gm/dl). Results: A total of 24 patients developed a periprocedural myocardial injury, among them 17 (70.8%) were in the reduced haemoglobin group and 7 (29.2%) in the normal haemoglobin group. Elevation of troponin I after PCI was higher in group II than in group I patients with a statistically significant difference. Multivariate logistic regression analysis showed that haemoglobin reduction was an independent predictor of PMI (OR 1.94; 95% CI, 1.241-8.684; p = 0.01). Conclusion: Periprocedural haemoglobin reduction in patients with unstable angina was associated with myocardial injury after percutaneous coronary intervention (PCI).

Unmasking the Viral Veil: Exploring the Cardiovascular Intrigue of Pathogenic Infections

Published on: 23rd November, 2023

The intricate interplay between viral infections and cardiovascular complications has garnered significant attention from 2018 to 2023. Extensive research during this period has unveiled substantial connections between various viruses and cardiovascular diseases. Notable examples include Cytomegalovirus (CMV), coxsackievirus, influenza, Human Immunodeficiency Virus (HIV), Epstein-Barr Virus (EBV), Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), as well as coxsackievirus A and B, enteroviruses, adenovirus, and parvovirus B19. These viruses exert diverse influences on cardiovascular health through various pathways, contributing to endothelial dysfunction, inflicting direct damage on cardiac tissue, and triggering inflammatory responses. The intricate interplay between viral infections and cardiovascular health underscores the importance of considering viral pathogens within the framework of cardiovascular disease development, clinical management practices, and future research initiatives. This systematic review comprehensively scrutinizes the cardiovascular impacts stemming from various viral infections, casting a revealing light on their underlying mechanisms and associated clinical implications. These valuable insights can guide clinical management strategies, preventive measures and further investigations into the complex connection between viral infections and cardiovascular diseases, emphasizing the necessity for ongoing research and vigilance in comprehending and managing these pathogen-induced cardiac manifestations.

Aspirin for Primary Prevention of Cardiovascular Disease: What We Now Know

Published on: 9th January, 2024

Cardiovascular disease (CVD), including coronary artery disease and stroke, is the leading cause of death worldwide. Advances in primary and secondary prevention of CVD have improved patient prognoses and outcomes, however, it is imperative that the clinician and patient engage in early risk factor screening and preventive management of modifiable risk factors for CVD. In addition to blood lipid and blood pressure lowering medications, aspirin has been a long-standing therapy targeted to the prevention of CVD based on its antiplatelet and anti-inflammatory activity. However, recent articles and reports on updates to clinical guidelines for the primary prevention of CVD have resulted in confusion about aspirin recommendations. This review aims to assess the latest guidance on aspirin in CVD prevention and how to identify appropriately at-risk patients who may benefit from low-dose aspirin therapy as part of their CVD preventive healthcare choices. Additionally, this review will provide practical application guidance about clinician-patient conversations to clearly explain the benefits and risks of aspirin use and ensure a patient-centric decision to initiate aspirin therapy.

Impact of Chronic Kidney Disease on Major Adverse Cardiac Events in Patients with Acute Myocardial Infarction: A Retrospective Cohort Study

Published on: 5th February, 2024

Background: Acute Myocardial Infarction (AMI) results in a reduction in patients’ life expectancy. Different risk factors affect the risk of Major Adverse Cardiac Events (MACE). Although the role of kidney dysfunction in patients with Chronic Kidney Disease (CKD) in cardiac events has been identified, many patients with AMI are unaware of their underlying kidney disease. This study aimed to compare the incidence of adverse cardiovascular events and identify predictors of major adverse cardiovascular events in the medium term among patients with and without renal dysfunction following AMI. Methods: This retrospective cohort study was conducted on 1039 patients who were hospitalized for Acute Myocardial Infarction (AMI) between 2018 and 2019. The patient cohort comprised 314 women (mean age: 69.8 ± 13.2 years) and 725 men (mean age: 60.5 ± 13.8 years). Patient data were obtained from the registry of patients with acute myocardial infarction and the participants were followed up for a minimum of one year following hospital discharge to assess the incidence of MACE.Results: The study found that patients with a Glomerular Filtration Rate (GFR) level below 60 had a significantly higher mortality rate than those with a GFR level of 60 or above (15.7% vs. 3.5%,p < 0.0001). The multivariate analysis showed that Diabetes Mellitus (DM), GFR, and Non-ST Elevation Myocardial Infarction (NSTEMI) are significant risk factors for cardiovascular events. (p = 0.016, p = 0.015, p = 0.006 respectively), while variables such as sex, age, and Hypertension (HTN) were not significant risk factors. There was a negative correlation between GFR and death (0.241 - = r, p < 0.0001)Conclusion: This study highlights the importance of detecting kidney disease during an AMI and managing risk factors for cardiovascular disease to improve health outcomes and reduce the risk of mortality.

The Ketogenic Diet: The Ke(y) - to Success? A Review of Weight Loss, Lipids, and Cardiovascular Risk

Published on: 6th March, 2024

Background: Obesity remains a global epidemic with over 2.8 million people dying due to complications of being overweight or obese every year. The low-carbohydrate and high-fat ketogenic diet has a rising popularity for its rapid weight loss potential. However, most studies have a maximal 2-year follow-up, and therefore long-term adverse events remain unclear including the risk of Atherosclerotic Cardiovascular Disease (ASCVD).Results: Based on current evidence on PubMed and Google Scholar, there is no strong indication ketogenic diet is advantageous for weight loss, lipid profile, and mortality. When comparing a hypocaloric ketogenic diet with a low-fat diet, there may be faster weight loss until 6 months, however, this then appears equivalent. Ketogenic diets have shown inconsistent Low-Density Lipoprotein (LDL) changes; perhaps from different saturated fat intake, dietary adherence, and genetics. Case reports have shown a 2-4-fold elevation in LDL in Familial hypercholesterolaemic patients which has mostly reversed upon dietary discontinuation. There is also concern about possible increased ASCVD and mortality: low (< 40%) carbohydrate intake has been associated with increased mortality, high LDL from saturated fats, high animal product consumption can increase trimethylamine N-oxide, and cardioprotective foods are likely minimally ingested.Conclusion: Ketogenic diets have been associated with short-term positive effects including larger weight reductions. However, by 2 years there appears no significant differences for most cardiometabolic risk markers. Therefore, this raises the question, excluding those who have a critical need to lose weight fast, is this diet worth the potentially higher risks of ASCVD and mortality while further long-term studies are awaited?
