Abstract 4139940: Safety and Efficacy of Self-Expanding vs Balloon-Expandable Valves for Transcatheter Aortic Valve Replacement in Patients with Aortic Stenosis: A Systematic Review and Real-World Meta-Analysis

Circulation, Volume 150, Issue Suppl_1, Page A4139940-A4139940, November 12, 2024. Background:There are two approved methods for transcatheter aortic valve replacement (TAVR) namely balloon-expandable valves (BEV) and self-expanding valves (SEV). While several randomized controlled trials (RCTs) have compared the efficacy of SEV and BEV, the generalizability of their findings is questioned. Therefore, to generate concrete evidence regarding the superiority between the two, we conducted this real-world meta-analysis to compare the clinical efficacy and safety outcomes of SEV vs BEV in patients undergoing TAVR for aortic stenosis (AS).Methods:MEDLINE, EMBASE, and Scopus were queried to shortlist studies including AS patients undergoing TAVR. Primary outcomes included 30-day and 1-year all-cause and cardiac mortality. Secondary outcomes were permanent pacemaker implantation (PPI), paravalvular leak (PVL), aortic regurgitation (AR), stroke, major vascular complications (MVC), major bleeding (MB), acute kidney injury (AKI), myocardial infarction (MI), length of stay (LOS), patient prosthesis mismatch (PPM), and atrial fibrillation (AF). A random effects meta-analysis was conducted to derive risk ratios and mean differences with corresponding 95% confidence intervals (CI).Results:Our meta-analysis included 38 real-world studies. No significant association was seen in 30-day (RR=1.13, P=0.15) and 1-year all-cause mortality (RR=1.04, P=0.55), and cardiac mortality (RR=1.28, P=0.12). SEV was associated with a higher risk of 30-day PPI (RR=1.61, 95% CI 1.28-2.02, I2 = 88%, P

Abstract 4131100: Effect of metabolic surgery on cardiovascular outcomes in people with obesity and pre-existing cardiovascular disease: A systematic review and meta-analysis

Circulation, Volume 150, Issue Suppl_1, Page A4131100-A4131100, November 12, 2024. Background:Previous literature shows that metabolic surgery effectively decreases the risk of cardiovascular disease (CVD) events in patients with obesity. The use of metabolic surgery has, however, been limited in people with obesity and pre-existing CVD due to concerns of poor post-operative cardiovascular outcomes. This study aims to determine the effectiveness and safety of metabolic surgery in patients with pre-existing CVD.Methods:A search of electronic databases, PubMed, Cochrane Central and SCOPUS was conducted from their inception till May 2024. The study was conducted adhering to the PRISMA guidelines. Outcomes of interest were risk of all-cause mortality, major adverse cardiovascular events (MACE), risk of myocardial infarction (MI), and cerebrovascular events in patients with and without prior CVD undergoing bariatric surgery. Data was pooled as generic inverse variance using a random effects model, and presented as hazard ratios (HR) with their 95% confidence intervals (CI).Results:We included four studies in our analysis (n = 5,244). Our pooled analysis shows that metabolic surgery leads to significant reduction in risk of all-cause mortality (HR = 0.51, 95% CI: [0.42, 0.61]; p

Abstract 4145010: Efficacy of Autologous Stem Cell Therapy in Myocardial Infarction and Ischemic Cardiomyopathy: A Systematic Review and Meta-Analysis

Circulation, Volume 150, Issue Suppl_1, Page A4145010-A4145010, November 12, 2024. Introduction:Coronary heart disease(CHD) and myocardial infarction(MI) cost American healthcare $99 billion annually. In the US, 20.5 million adults over 20 years of age suffer from CHD, and 9.3 million from MI. MI causes cardiac myocyte death and scarring, leading to ischemic cardiomyopathy (ICMY), heart failure(HF), and arrhythmia. Current treatments improve perfusion and prevent remodeling but cannot reverse scarring. Stem cell therapy(SCT) aims to replace scarred myocardium with viable tissue, preventing complications like ICMY and HF.Aims:Evaluating the efficacy of SCT, in treating MI and preventing ICMY and HF. Efficacy was measured after 6 months, 1 year, and the long term.Methods:We followed the PRISMA protocol and guidelines to identify all human clinical trials on PubMed since 2010 that used SCT in adults with MI. Observational, non-human studies and isolated case reports were excluded. Our population of interest: adults with MI and SCT were compared to the control group of standard therapy alone(ST). Cardio sphere-derived autologous stem cells, Autologous Bone Marrow Stem Cell Therapy, Bone marrow-derived mononuclear cells via anterograde intra-arterial coronary delivery, Intracoronary infusion of autologous CD34 (+) cell, and Mesenchymal Stem/Stromal Cells were utilized in these trials. The primary outcome measured was efficacy: defined as an increase in Left Ventricular Ejection Fraction(LVEF) by >10%.Results:More than 3000 articles were reviewed, and after applying rigorous inclusion and exclusion criteria, we narrowed down to 32 articles with 2613 patients for qualitative and quantitative analysis. We found an increase in LVEF of >10% with optimal treatment after 12 months of management in the SCT (P

Abstract 4113561: Efficacy and Outcomes of Empagliflozin in Acute Coronary Syndrome Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Circulation, Volume 150, Issue Suppl_1, Page A4113561-A4113561, November 12, 2024. Background:Sodium-glucose co-transporter 2 inhibitors (SGLT2i) have demonstrated mortality benefits in patients with heart failure (HF). Since acute coronary syndrome (ACS) is an increasingly prevalent cardiovascular condition that often leads to HF, SGLT2i might play a role in reducing mortality in these patients. Previous randomized controlled trials (RCTs) have demonstrated inconsistent efficacy of Empagliflozin, an SGLT2i, in patients with ACS.Methods:A comprehensive systematic literature search was conducted spanning the major bibliographic databases to retrieve RCTs comparing Empagliflozin to placebo in patients with ACS. Odds ratios (OR) and mean differences (MD) with 95% confidence intervals were pooled using the DerSimonian and Laird random-effects model with statistical significance set at p

Abstract 4148181: Neutrophil and Leucocyte Ratio and LDL to HDL ratios as predictors of Hemorrhagic transformation in ischemic stroke patients : A systematic review

Circulation, Volume 150, Issue Suppl_1, Page A4148181-A4148181, November 12, 2024. Background:Following an ischemic stroke, a serious complication known as hemorrhagic transformation (HT) might jeopardize patient outcomes. Inflammatory indicators, such as the neutrophil-to-leukocyte ratio (NRR), and lipid markers, such as the low-density lipoprotein (LDL) to high-density lipoprotein (HDL) ratio, have been investigated as HT predictors. Recent research has delved further into the predictive significance of these biomarkers for ischemic stroke outcomes.Objectives:To systematically review the literature on the predictive value of NLR and LDL to HDL ratios for HT in ischemic stroke patients, incorporating recent findings that enhance our understanding of these biomarkers.Methods:A detailed search of electronic databases was conducted to gather studies focusing on NLR and LDL to HDL ratios as predictors for HT in ischemic stroke. The selection process followed strict inclusion criteria, and the quality of studies was rigorously assessed.Results:The paper discusses new findings that emphasize the impact LDL and NLR play in influencing HDL ratios and, hence, HT prediction. Following an ischemic stroke, an increased incidence of HT, especially parenchymal hematoma (PH), has been associated with greater NLR. A high neutrophil-to-HDL ratio (NHR) has also been identified as a possible predictor of poor prognosis in ischemic stroke, underscoring its significance in predicting HT. Furthermore, the LDL-to-HDL ratio has been connected to long-term clinical outcomes like death and recurrent myocardial infarction, which may be associated with HT risk.Conclusions:In individuals with ischemic stroke, NLR and LDL-to-HDL ratios are potential HT indicators. The addition of current data underscores the potential of these ratios not just as HT indicators but also as markers for broader stroke-related effects. More studies are needed to validate these results and provide consistent recommendations for their use in clinical practice.

Abstract 4141761: Safety and Efficacy of Radial Versus Femoral Access for Rotational Atherectomy: An Updated Systematic Review And Meta-Analysis

Circulation, Volume 150, Issue Suppl_1, Page A4141761-A4141761, November 12, 2024. Background:Rotational atherectomy has been performed using both radial and femoral access over the years, but there is a lack of consensus on the safety and efficacy of these access sites.Aim:To assess the safety and efficacy of radial access and femoral access.Methods:MEDLINE, Scopus, and Cochrane Library were searched until May 2024 for studies comparing radial approach with femoral approach in patients undergoing rotational atherectomy. The primary outcome was major vascular site bleeding. Secondary outcomes included short-term mortality, long-term mortality, myocardial infarction, major adverse cardiovascular events (MACE), acute stent thrombosis, procedural success, procedural time, hospital stay and radiation exposure. Effect estimates were synthesized using a random-effects model and expressed as risk ratios (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes, with corresponding 95% confidence intervals (CIs).Results:13 studies including 13,581 patients with mean age of 60.76 years in the radial group and 66.86 years in the femoral group, who had undergone rotational atherectomy, were included in the analysis. For the outcome of major vascular site bleeding, there was significantly lower risk (RR: 0.25; 95% CI [0.15, 0.43]; p

Abstract 4147717: Sodium Glucose Cotransporter 2 Inhibitors on Chronic Heart Failure with Reduced Ejection Fraction in Adult Congenital Heart Disease Patients: A Systematic Review and Meta-analysis

Circulation, Volume 150, Issue Suppl_1, Page A4147717-A4147717, November 12, 2024. Background:SGLT2 inhibitors have demonstrated efficacy in reducing cardiovascular death and hospitalization and are recommended as first-line therapy for hear failure (HF) in adults due to acquired heart diseases. Our study aimed to assess the safety, tolerability, and outcomes of HF patients with adult congenital heart disease (ACHD) treated with SGLT2 inhibitors.Methods:We conducted a comprehensive search of three major databases—PubMed, Scopus, and Embase—and collected articles on the use of SGLT2 inhibitors for HF in ACHD patients who were already receiving angiotensin-converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARB), angiotensin receptor neprilysin inhibitors (ARNI), beta-blockers (BB), and mineralocorticoid antagonists (MRA). We excluded articles related to acute decompensated HF and HF with preserved ejection fraction. The primary outcome was the change in NYHA functional class (FC). Secondary outcomes included changes in B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NT-proBNP) levels, as well as body weight. Additionally, we evaluated the safety and tolerability of SGLT2 inhibitors in ACHD HF patients. A pooled effect size was calculated based on mean differences (MD) or log odds ratio (LogOR).Results:Our meta-analysis included 9 studies with a total of 287 patients aged 19 to 67 (median 37.5 years) (Table). When SGLT2 inhibitors were added to combined therapies, they significantly improved NYHA FC (LogOR: 1.3, 95% CI: 0.37–2.23, p=0.01) (Figure 1A), decreased NT-proBNP (MD -0.43, 95% CI -0.70 to -0.16, p=0.00) (Figure 1B), were associated with a reduction in systolic blood pressure (MD = -0.32, 95% CI: -0.51 to 0.14, p=0.00) (Figure 1C), and led to an elevation of creatinine (Cr) levels (MD = 0.18, 95% CI -0.0 to 0.36, p=0.06) (Figure 1D). Only 4 patients experienced urinary tract infections (UTIs), and none had hypoglycemia or ketoacidosis.Conclusion:Our meta-analysis demonstrates that SGLT2 inhibitors improve NYHA FC, decrease NT-proBNP, and are well-tolerated with safety features similar to adult HF clinical trials when added to combination HF therapies including ACEI/ARB/ARNI, BB and MRA. Future prospective studies are needed to assess long-term clinical outcomes in ACHD patients with HF.

Abstract 4136346: A Comparative Analysis of Esophageal Cooling for Preventing Esophageal Injury Post Atrial Fibrillation Catheter Ablation: A Systematic Review and Meta-analysis

Circulation, Volume 150, Issue Suppl_1, Page A4136346-A4136346, November 12, 2024. Introduction:Thermal injury following atrial fibrillation catheter ablation is a rare but fatal complication. We aim to assess the safety profile of different forms of esophageal cooling methods versus standards of care.Methods:We searched PubMed, Cochrane Library, Scopus, and Web of Science databases for randomized controlled trials and cohort studies comparing esophageal cooling to Luminal esophageal temperature (LET) monitoring regarding esophageal thermal lesions (ETL) post atrial fibrillation ablation. Case reports, case series, reviews, conference abstracts and animal studies were excluded. Review manager software (version 5.4) was used to perform the meta-analysis.Results:We included 10 studies with 25662 patients in total: 14515 patients in the esophageal cooling group and 11147 patients in the LET group. Overall esophageal lesion analysis demonstrated no statistically significant difference between the esophageal cooling group and LET (RR = 0.72, 95% CI = 0.35 to 1.49, p-value = 0.38). Subgroup analysis showed no statistically significant difference for mild/moderate lesions (RR = 1.52, 95% CI = 0.80 to 2.90, p-value = 0.20). However, the subgroup analysis showed a statistically significant association between esophageal cooling and decreased severity of esophageal lesions compared with LET (RR = 0.29, 95% CI = 0.12 to 0.71, p-value = 0.007). Regarding AF recurrence, the pooled analysis showed no statistically significant difference between esophageal cooling group and LET (RR = 1.24, 95% CI = 0.95 to 1.61, p-value = 0.11).Conclusion:In patients undergoing AF catheter ablation, the implementation of esophageal cooling showed statistical significance in decreasing the severity of esophageal lesions compared to the LET group. Also, esophageal cooling demonstrated non-inferiority in AF recurrence compared to LET. Future research should focus on assessing the long-term effects of esophageal cooling during AF catheter ablation.

Abstract 4138622: Cardiac Rhabdomyosarcoma: An Updated Review of the English Literature From 1980 Through 2023

Circulation, Volume 150, Issue Suppl_1, Page A4138622-A4138622, November 12, 2024. Cardiac Rhabdomyosarcoma (CR) is a rare malignant neoplasm of the heart occurring in all age groups and genders. It can arise anywhere in the heart with varied clinical presentation. Available data on CR are mainly from case reports and series that are limited by small sizes. The purpose of this study was to characterize the epidemiology, presentation, management, hospital course, and outcomes of CR published in the English literature from 1980-2023.Methods:We reviewed and included all published case reports with a diagnosis of CR in adult patients (age >18 years) on PubMed and Google Scholar using the keywords “primary cardiac tumor” and “cardiac rhabdomyosarcoma”. Data was extracted onto an Excel spreadsheet for analysis and the outcomes of interest were demographics, clinical presentation, diagnostic modalities, management, complications, and outcomes. We used descriptive statistics to analyze the data.Results:Among a total of 97 patients from 19 countries included in this study, 54% were males and the median age was 49 years (range 18-80). The main symptoms were dyspnea (37.1%), palpitations (23.7%), chest pains (16.5%) and syncope (6.5%). Hypotension or heart failure and arrhythmias were present in 10.3% and 9.3%, respectively and 5.2% had pericardial effusion. In addition to those with metastatic tumors, 22.7% had chronic co-morbidities. The majority of the cases were primary tumors (85.6%), and the remainder were (14.4%). All patients had at least one imaging modality including echocardiography (89%) and CT/MRI (84%). The commonest sites of cardiac involvement were the left atrium (35%), right atrium (33%), right ventricle (20%), and left ventricle (12%). Approximately 68% involved a single cardiac site while 32% involved multiple sites. Among the patients, 96% underwent surgery while 33% and 25% had chemotherapy and 25% radiotherapy, respectively. The median length of hospital stay was 11 days (range, 2-68 days), and mortality was recorded in 79.3% (77/97) of the patients. The median survival time was reported in 42 patients, and it was 6 months (range, 0-36 months).Conclusion:Cardiac rhabdomyosarcoma is a rare and aggressive malignant neoplasm. Most cases are primary tumors with poor outcomes such as a very short median survival time and a very high mortality rate despite the combination of surgery, chemotherapy, and radiotherapy. This calls for further research into the early diagnosis and optimal management strategies to improve outcomes.

Abstract 4146268: Apolipoprotein A1 infusion in patients with Acute Myocardial Infarction: A Systematic Review and Meta-analysis of randomized trials

Circulation, Volume 150, Issue Suppl_1, Page A4146268-A4146268, November 12, 2024. Background:Low cholesterol efflux is associated with increased cardiovascular (CV) event risk. CSL112 is a reconstituted, infusible human plasma-derived apolipoprotein A-I that enhances cholesterol efflux, but its efficacy in reducing CV events is unclear. We aim to conduct a systematic review and meta-analysis comparing CSL112 infusions with placebo in acute myocardial infarction patients.Methods:We searched Cochrane, Embase and Pubmed databases for randomized controlled trials (RCT). The outcomes of interest were: (1) all-cause mortality; (2) emergent serious adverse events (SAE); and (3) major adverse cardiovascular events (MACE). Heterogeneity was examined with I2 statistics.We pooled risk ratios (RR) with 95% confidence intervals (CI) using a random effects model. Statistical analysis was done using R Studio 4.3.2.Results:Three RCTs were included, encompassing 19,557 patients, of whom 10,004 (51%) were in the CSL112 group. Most of the participants were male (74.5%), with a mean age of 65.1 years and a mean follow-up of 11.6 months. In the pooled analysis, there was no significant statistical difference in all-cause mortality (RR 1.06; 95% CI 0.57, 1.97; p=0.86; I2=19%; Fig 1), SAE (RR 1.01; 95% CI 0.84, 1.22; p=0.90; I2=48%; Fig 2A), and MACE (RR 0.94; 95% CI 0.83, 1.06; p=0.32; I2=0%; Fig 2B).Conclusion:Our findings suggest that the administration of CSL112 was not associated with a reduction in mortality, SAE or MACE in patients with acute myocardial infarction.

Abstract 4140060: Impact of SGLT2 Inhibitors on Mortality Risk in Type 2 Diabetes Mellitus and Coronary Artery Disease: A Systematic Review and Meta-Analysis

Circulation, Volume 150, Issue Suppl_1, Page A4140060-A4140060, November 12, 2024. Introduction:Type 2 diabetes mellitus (T2DM) is a major risk factor for coronary artery disease (CAD). SGLT2 inhibitors (SGLT2i) are effective in reducing cardiovascular mortality in T2DM patients, but their benefits for those with both CAD and T2DM are uncertain.Objective:The primary outcome was to evaluate the efficacy of SGLT2i compared to other hypoglycemic agents or placebo in reducing the risk of all-cause mortality in patients with T2DM and CAD. Secondary outcomes included cardiovascular death, fatal or non-fatal stroke, and fatal or non-fatal myocardial infarction. We hypothesize that SGLT2i are more effective in mortality risk reduction in patients with T2DM and concomitant CAD.Methods:A systematic review following PRISMA-2020 guidelines was conducted across four databases to evaluate the efficacy of SGLT2i in reducing mortality risk in diabetic patients with CAD. Quantitative analysis using Stata v18 employed a random-effects model (Restricted Maximum Likelihood) with Hazard Ratios (HR) as the measure of association.Results:Out of 853 studies identified, 5 publications were included in the final quantitative analysis, which included 5225 patients. The Newcastle-Ottawa Quality Assessment Form showed all included cohort studies had a low risk of bias. Those patients taking SGLT2i had a significant reduction in 38% the risk of all-cause mortality (HR 0.62 [0.47, 0.80]), this same effect was observed when compared with each subgroup vs. other hypoglycemic agents, HR 0.52 [0.29, 0.93]; vs. placebo, HR 0.64 [0.46, 0.90]. Results show very low heterogeneity. In overall cardiovascular death analysis, a significantly greater reduction was observed with SGLT2i (HR 0.61 [0.46, 0.81]), as well as when compared with placebo (HR 0.64 [0.47, 0.86]). In contrast, when compared with other hypoglycemic agents, there was a reduction, but this was not significant (HR 0.45 [0.19, 1.03]). No statistically significant decrease in the risk of fatal or non-fatal stroke and myocardial infarction was found with SGLT2i.Conclusion:SGLT2i demonstrates a greater significant benefit in reducing all-cause and cardiovascular mortality in patients with T2DM and CAD.

Abstract 4145225: Sodium Glucose Cotransporter 2 Inhibitors After Acute Myocardial Infarction: An updated systematic review and meta-analysis.

Circulation, Volume 150, Issue Suppl_1, Page A4145225-A4145225, November 12, 2024. Background:Sodium-glucose co-transporter two inhibitors (SGLT2i) have recently been included in heart failure (HF) guidelines due to their benefits in reducing mortality and hospitalization rates. However, the benefits of SGLT2i in patients with post-acute myocardial infarction (MI) remain controversial. Therefore, we aim to perform an updated systematic review and meta-analysis comparing SGLT2i with placebo in patients after an acute MI.Methods:We performed a systematic review and meta-analysis to determine the impact of SLGT2i in patients with post-acute MI with or without diabetes type II (DM II). We systematically searched Pubmed, Cochrane, and Embase for randomized controlled trials (RCTs) comparing SGLT2i and placebo in patients following an acute MI. The primary outcome assessed was (1) HF hospitalization. In this analysis, we also included the following secondary outcomes:(2) cardiovascular (CV) mortality and (3) MI recurrence. Risk Ratios(RRs) with 95% confidence interval (CI) were pooled across studies using a random effect model.Results:Our meta-analysis included ten RCTs comprising 25908 patients, of whom 14098 (54.4%) received SGLT2i therapy and 15078 (58.2%) had type II diabetes. The mean age was 62 years, and the mean follow-up was 21.2 months. In the pooled analysis, HF hospitalization was significantly lower in the SGLT2is group (RR 0.76; 95%CI 0.68,0.84; p

Abstract 4139688: Empagliflozin versus Placebo in Patients with Cardiovascular Disease and Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis

Circulation, Volume 150, Issue Suppl_1, Page A4139688-A4139688, November 12, 2024. Background:Historically, patients with type 2 diabetes mellitus (T2DM) and concurrent cardiovascular disease (CVD) have been managed through multifactorial interventions, including lifestyle modifications. Recently, empagliflozin, a potent sodium-glucose cotransporter 2 inhibitor (SGLT2i), has emerged as a novel antidiabetic agent demonstrating significant improvements in cardiovascular outcomes.Aim:To conduct a meta-analysis comparing empagliflozin with placebo in patients with T2DM and concomitant CVD.Methods:We performed a thorough literature search of PubMed, EMBASE, and the Cochrane Library up to May 2024 to identify studies comparing empagliflozin with placebo in patients with T2DM and concomitant CVD. Effect estimates were pooled using a random-effects model and reported as risk ratios (RR) for dichotomous outcomes and standard mean difference (SMD) or mean differences (MD) for continuous outcomes, each accompanied by 95% confidence intervals (CIs). Due to varying units of measurement for HbA1c that were not interconvertible, SMD was employed. Conversely, MD was used for the analysis of other continuous outcomes.Results:16 studies fulfilled the inclusion criteria. Empagliflozin significantly reduced HbA1c (SMD: -1.33 [-2.28, -0.38]; p=0.006;Figure) and cardiac mortality (RR= 0.62 [0.50, 0.78]; p

Circulation, Volume 150, Issue Suppl_1, Page A4142244-A4142244, November 12, 2024. Background:Multivessel coronary artery disease has a higher risk of adverse cardiovascular outcomes. Although patients presenting with STEMI usually undergo revascularization of the infarct-related artery only (i.e. cuplrit only percutaneous coronary intervention or CO-PCI), recent trials suggest improved outcomes with complete PCI of all arteries with chronic total occlusion (CTO).Aim:To meta-analyze data from randomized controlled trials comparing the impact of complete versus CO-PCI in STEMI patients with CTO in the non-infarct related artery (non-IRA).Methods:We conducted a comprehensive search of Medline, EMBASE, and Scopus up till May 2024, to identify studies comparing the clinical outcomes between CO-PCI versus complete PCI in patients with STEMI accompanied by CTO in the non-IRA. Effect estimates were pooled using a random-effects model and reported as risk ratios (RR) along with corresponding 95% confidence intervals (CIs), with a significant p value < 0.05. Outcomes of interest include all-cause and cardiac mortality, myocardial infarction and stroke.Results:Our search strategy yielded 16 eligible studies (complete PCI, n= 7,982; CO-PCI, n= 7,753). Complete PCI significantly reduced all-cause mortality in comparison to CO-PCI (RR=0.64 [0.49, 0.84]; p=0.002). Complete PCI was also associated with a significant reduction in cardiac death (RR: 0.54 [0.41 - 0.72]; p

Abstract 4145387: Cardiac Myosin inhibitors in patients with Symptomatic Hypertrophic Cardiomyopathy: An updated Systematic review and Meta-analysis of randomized trials.

Circulation, Volume 150, Issue Suppl_1, Page A4145387-A4145387, November 12, 2024. Background:Current therapeutic options for relieving symptoms in hypertrophic cardiomyopathy (HCM) predominantly involve invasive interventions. In contrast, cardiac myosin inhibitors (CMI), such as aficamten and mavacamten, represent a promising pharmacological alternative to alleviate left ventricular outflow tract obstruction. However, there is limited data regarding the efficacy of this therapy.Methods:We searched Pubmed, Cochrane, and Embase databases for randomized controlled trials (RCT) comparing CMI with placebo among symptomatic HCM patients. Key outcomes assessed included: (1) improvement in at least one New York Heart Association (NYHA) functional class, (2) enhancement in the Kansas City Cardiomyopathy Questionnaire – Clinical Summary Score (KCCQ-CSS), and (3) change in N-terminal pro b-type Natriuretic Peptide (NT-proBNP) levels. Statistical analyses were performed using R Studio 4.3.2.Results:Six RCTs were included, involving 826 patients, of whom 443 (53.6%) were assigned to the CMI group. The majority of participants were male (57%), with a mean age of 57.9 years and a mean follow-up duration of 21 weeks. In the pooled analysis, CMI was associated with a significant improvement of at least one NYHA functional class (RR 2.21; 95% CI 1.75, 2.80; p
