In-Hospital Outcome In Patients With Acyanotic Congenital Heart Disease Undergoing Transcatheter Aortic Valve Replacement.

The purpose of the study was to determine the in-hospital outcome and resource utilization in patients with acyanotic congenital heart disease (ACHD) undergoing transcatheter aortic valve replacement (TAVR). Current guidelines from professional societies do not support TAVR in patients with ACHD, likely from a lack of supportive evidence. Temporal trends in patients with ACHD undergoing TAVR were determined using the 2016-2018 National Inpatient Sample database appropriate ICS-10-PCS code. Stata 16.0 was used for statistical analysis. 0.87% of patients undergoing TAVR had concomitant ACHD, with ASD being the most common (78%). After matching, there was no increased risk of mortality in ACHD patients undergoing TAVR compared to patients without ACHD (OR 1.43, P = 0.59). Additionally, no difference was found in the incidence of overall cardiac complications between patients with ACHD and patients without ACHD, except STEMI (OR 4.16, 95% CI, 1.08-16.00, P = 0.038), which is likely due to more comorbidity burden in the later cohort. Complications such as acute kidney injury, ischemic stroke, and bleeding were similar. Hospital resource utilization was higher in the ACHD group in the form of increased length of stay and higher mean total cost. The comparable in-hospital all-cause mortality and complication rate in ACHD patients undergoing TAVR compared to patients without ACHD is encouraging and will be helpful to design future randomized controlled trials

Rural Posting for Medical Graduates: Perception, Acceptance and Plausibility

Introduction: India is facing acute shortage of doctors in rural areas. The government wants to make it compulsory for all MBBS graduates who have completed their internship to do one year of rural service if they wish to pursue post-graduation. Objective: The current study was planned to assess feasibility and acceptability of rural posting among medical students. Materials and Methods: It was a mixed-approach study design with both qualitative and quantitative approach conducted among 163 medical undergraduate students from three major medical colleges of Delhi. Focus group discussions (FGDs) were conducted among medical students followed by a cross-sectional questionnaire based research. Data was analyzed using SPSS software version 17. Quantitative data was presented in mean±SD and proportion. For qualitative data, thematic analysis was done. Results: A total of 163 students participated in the study. 123 (75.5%) of participants were females and 40 (23.3%) were males with a mean age of 19.92±2.45 years. Less than 15% of the students accepted positively for rural posting. Insufficient incentive, security problems, cultural differences from the rural population, lack of infrastructure in rural settings, political motives in implementing rural posting, etc., were main reasons discouraging students from rural posting. Conclusion: It can be concluded that acceptability of rural posting was poor among medical students. Lack of infrastructure, security, and inadequate monetary incentives were some of the major issues for implementation of compulsory rural posting

The Role of Dapagliflozin in the Management of Heart Failure: An Update on the Emerging Evidence.

The burden and cost of heart failure management, primarily in the form of hospitalization in the setting of decompensated heart failure, continue to be some of the biggest clinical challenges in cardiovascular medicine. In recently published randomized controlled trials, including DAPA-HF, sodium-glucose cotransporter 2 (SGLT2) inhibitor dapagliflozin was shown to reduce hospitalization from heart failure or mortality associated with cardiovascular causes, when added to existing guideline-directed medical therapy. The American College of Cardiology (ACC) released a Clinical Pathway guideline that recommends the use of dapagliflozin in clinical management of heart failure, with or without diabetes. Furthermore, the results of the DAPA-CKD trial broaden the utility of dapagliflozin as a therapeutic option in patients with advanced kidney disease. In this article, the authors explore the existing evidence on dapagliflozin in heart failure with reduced ejection fraction and highlight the need for further research on uses of dapagliflozin in the world of heart failure

COVID-19, Mucormycosis and Cancer: The Triple Threat—Hypothesis or Reality?

COVID-19 has been responsible for widespread morbidity and mortality worldwide. Invasive mucormycosis has death rates scaling 80%. India, one of the countries hit worst by the pandemic, is also a hotbed with the highest death rates for mucormycosis. Cancer, a ubiquitously present menace, also contributes to higher case fatality rates. All three entities studied here are individual, massive healthcare threats. The danger of one disease predisposing to the other, the poor performance status of patients with all three diseases, the impact of therapeutics for one disease on the pathology and therapy of the others all warrant physicians having a better understanding of the interplay. This is imperative so as to effectively establish control over the individual patient and population health. It is important to understand the interactions to effectively manage all three entities together to reduce overall morbidity. In this review article, we search for an inter-relationship between the COVID-19 pandemic, emerging mucormycosis, and the global giant, cancer

An update on pharmacotherapies in diabetic dyslipidemia

Hyperlipidemia plays a crucial role in the underlying pathogenesis of multiple cardiovascular diseases (CVD), including coronary artery disease, peripheral arterial disease, carotid stenosis, and heart failure. The risk of developing such diseases in the diabetic population is relatively high. Diabetes mellitus (DM) is an independent risk factor for premature atherosclerosis. The hallmark of DM dyslipidemia is a demonstrably high level of atherogenic triglyceride rich lipids including very low-density lipoprotein, chylomicrons, and small dense low-density lipoprotein (LDL). Moderate to high intensity statins, targeting LDL cholesterol reduction, remain the cornerstone in the management of this unique disorder. Many ‘non-statin’ drugs have recently been studied in the DM patients who were either on a ‘maximally tolerated statin’ or ‘statin intolerant’. Ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are particularly important and were incorporated in the recent guidelines by the European Society of Cardiology, American College of Cardiology, American Heart Association, and American Diabetes Association. Icosapent Ethyl has garnered huge interest this year following publication of the REDUCE-IT trial. There are several newer hypolipidemic drugs, including Bempedoic acid, Inclisiran and RVX-208, that are in different phases of clinical trials. In this article, we review the underlying pathophysiology of DM dyslipidemia, existing guidelines related to its management, and the potential of newer hypolipidemic and anti-inflammatory drugs being incorporated in the management of DM

Proposed Pathogenesis, Characteristics, and Management of COVID-19 mRNA Vaccine-Related Myopericarditis

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the novel coronavirus causing coronavirus disease 2019 (COVID-19), has affected human lives across the globe. On 11 December 2020, the US FDA granted an emergency use authorization for the first COVID-19 vaccine, and vaccines are now widely available. Undoubtedly, the emergence of these vaccines has led to substantial relief, helping alleviate the fear and anxiety around the COVID-19 illness for both the general public and clinicians. However, recent cases of vaccine complications, including myopericarditis, have been reported after administration of COVID-19 vaccines. This article discusses the cases, possible pathogenesis of myopericarditis, and treatment of the condition. Most cases were mild and should not yet change vaccine policies, although prospective studies are needed to better assess the risk-benefit ratios in different groups

Bempedoic Acid and Its Role in Contemporary Management of Hyperlipidemia in Atherosclerosis

Atherosclerotic heart disease is the leading cause of mortality and morbidity in the USA. Low density lipoprotein (LDL) has been the target for many hypolipidemic agents to modify atherosclerotic risk. Bempedoic acid is a novel hypolipidemic drug that inhibits the enzymatic activity of ATP citrate lyase in the cholesterol synthesis pathway. CLEAR Harmony, CLEAR Wisdom, CLEAR Tranquillity and CLEAR Serenity have shown safety and efficacy associated with long term administration of this drug. Studies have shown effectiveness in reducing LDL-C in both statin intolerant patients and in patients on maximally tolerated doses of statin. The fixed drug combination of bempedoic acid and ezetimibe in a recent phase III showed significant reduction in LDL compared with placebo, which might be a promising future for LDL reduction among statin intolerant patients. Bempedoic acid also reduced inflammatory markers like hs-CRP. Given these results, bempedoic acid alone and in combination with ezetimibe received the USA FDA approval for adults with heterozygous familial hypercholesterolaemia or established atherosclerotic cardiovascular disease. We present a comprehensive review exploring the underlying mechanism, pre-clinical studies, and clinical trials of bempedoic acid and discuss the potential future role of the drug in treating hyperlipidaemia

Sodium Glucose Co-transporter 2 Inhibitors and Heart Failure

Sodium-glucose co-transporter 2 (SGLT2) receptors are primarily located in the proximal convoluted tubule of the nephron. These receptors are responsible for almost 90% to 95% of tubular reabsorption of the glucose in the nephron. In patients with diabetes mellitus, due to upregulation of SGLT2 receptors, glucose reabsorption is further increased. The Food and Drug Administration approved SGLT2 inhibitors, such as canagliflozin, empagliflozin, dapagliflozin, and ertugliflozin, for the treatment of type 2 diabetes. In addition to their positive effect on blood glucose, additional cardioprotective and renoprotective functions have been demonstrated in major trials such as EMPA-REG OUTCOME, CANVAS, DECLARE-TIMI-58, and CREDENCE. Unlike other antihyperglycemic drugs, reduction in hospitalization for heart failure (HF) was also seen as a class effect with this group, mechanisms of which are probably multifactorial. Subgroup analysis from these major trials indicated a reduction in progression of nephropathy and HF readmission with SGLT2 inhibitors. Although this unique property of canagliflozin was further analyzed in the CREDENCE trial, similar trials for empagliflozin (EMPERIAL-Reduced and EMPERIAL-Preserved) and dapagliflozin (DAPA-HF) are currently underway. Recently released phase III results from DAPA-HF trial indicate that dapagliflozin shows significant reduction in death due to cardiovascular causes and hospitalization in HF compared with the placebo, in both diabetics and nondiabetics. In this review article, the authors attempt to explore the possible underlying molecular mechanisms and data from existing trials pertaining to the HF related outcomes associated with SGLT2 inhibitors

Novel emerging therapies in atherosclerosis targeting lipid metabolism

Introduction: Recent years have brought significant developments in lipid and atherosclerosis research. Although statins are a cornerstone in hyperlipidemia management, new non-statin therapies have had an impact. The reduction of low-density lipoprotein cholesterol (LDL-C) further translates into the lowering of cardiovascular mortality. Additionally, lipid research has progressed beyond LDL-C reduction and this has brought triglyceride (TG) and other apoprotein-B containing lipids into focus.Areas covered: Inclisiran and pemafibrate, with expected approval soon, come under the spotlight. We discuss other therapeutics such as lomitapide, mipomersen, volanesorsen, and evinacumab and newly approved non-statin-based therapies such as ezetimibe, icosapent ethyl (IPE), and bempedoic acid.Expert opinion: New options now exist for the prevention of atherosclerosis in patients that are not optimized on statin therapy. Multiple guidelines endorse ezetimibe, PCSK9 inhibitors, bempedoic, and IPE as add-on therapy. Recently approved bempedoic acid/ezetimibe combination might gain popularity among clinicians. Inclisiran and pemafibrate show promise in the reduction of LDL-C and TG, respectively, and results are pending in cardiovascular outcome trials. Combination strategies could improve outcomes, but the challenge will be balancing cost and selecting the correct patient population for each treatment modality to maximize benefit with the fewest medications
