Abstract Frailty is highly prevalent in cardiovascular disease and associates with poor clinical outcomes. Several cardiovascular conditions benefit from invasive interventions, but the impact of these procedures in frail patients remains unclear. We thus performed a systematic review and meta-analysis to summarize evidence and quantify the pooled effect of clinical outcomes of invasive cardiovascular interventions among frail vs. non-frail patients. Systematic search of two electronic databases from January 2015 to April 2025 was performed including all randomized controlled trials (RCTs) and prospective cohort studies examining outcomes of invasive cardiovascular interventions stratified by frailty. Outcomes included all-cause mortality, hospitalizations, and other adverse outcomes. Risk ratios (RRs) and their 95% confidence intervals (CI) were assessed using random-effects models. Thirty-one studies (10 RCTs, 21 prospective, 3 retrospective studies) with a total of 27 534 participants were included. Compared with non-frail patients, frail patients after cardiovascular procedures were at higher risks of all-cause mortality (RR 3.14, 95% CI: 2.29-4.30), and hospitalizations (RR 1.88, 95% CI: 1.29-2.73). Frail patients undergoing transcatheter aortic-valve implantation and percutaneous mitral-valve interventions did not have significant increased mortality risks compared with non-frail patients (P > 0.05). Pre-frailty predicted lower mortality risks amongst patients undergoing transcatheter vs. surgical aortic valve replacement (HR 0.78, 95% CI: 0.67-0.92). Frail patients with non-ST elevation myocardial infarction derived similar mortality benefits from an invasive vs. conservative approach (HR 1.13, 95% CI: 0.64-2.01). In conclusion, frailty prognosticates adverse outcomes following invasive cardiovascular interventions and influences treatment efficacy, highlighting its significance in treatment selection

Advances in plaque imaging have transformed cardiovascular diagnostics through detailed characterization of atherosclerotic plaques beyond traditional stenosis assessment. This review outlines the clinical applications of varying modalities, including dual-layer spectral CT, photon-counting CT, dual-energy CT, and CT-derived fractional flow reserve (CT-FFR). These technologies offer improved spatial resolution, tissue differentiation, and functional assessment of coronary lesions. Additionally, artificial intelligence has emerged as a powerful tool to automate plaque detection, quantify burden, and refine risk prediction. Collectively, these innovations provide a more comprehensive approach to coronary artery disease evaluation and support personalized management strategies.

Introduction: Amyloidosis complicated by heart failure (HF) poses significant mortality. We sought to identify trends in comorbid amyloidosis and HF mortality in the recent 22- year period. Methods: Mortality due to amyloid and HF as contributors of death were queried from death certificates using the CDC database from 1999 to 2020. Mortality rates and their 95% confidence intervals were adjusted for age (AAMR) through the Direct method and compared by demographic subpopulations. The Monte-Carlo permutation test was used to estimate the annual percentage change (APC). Log-linear regression models were utilized to assess temporal variation in mortality. Results: Age-adjusted mortality rates (AAMR) increased from 0.09 [0.08-0.10] in 1999 to 0.27 [0.25-0.29] in 2020. Mortality increased from 1999 to 2013 (APC +1.4, p=0.048) with an accelerating inflection point in 2013 to 2020 (APC +13.3, p<0.001). AAMR was higher among male populations (AAMR 0.20 [0.20-0.21]) compared to female populations (AAMR 0.07 [0.07- 0.07]). A significant inflection point in uprising mortality rates was observed for both male and female populations in 2013 (p<0.001). Mortality was highest among Black populations (AAMR 0.33), followed by White (AAMR 0.10), Asian/Pacific Islander (AAMR 0.06), and American Indian/Alaska Native populations (AAMR 0.04). Among Black populations, mortality remained consistent from 1999 to 2012 (APC +1.1, p=0.184), followed by an increase from 2012 to 2020 (APC +14.0, p<0.001). Among White populations, mortality remained stagnant from 1999 to 2013 (APC +0.7, p=0.302), followed by an increase starting in 2013 to 2020 (APC +13.5, p<0.001). Discussion: Our findings of a marked rise in HF-related mortality in patients with amyloidosis since 2013 highlighted the profound impact of enhanced diagnostic awareness, novel imaging techniques, and emerging therapeutics. Our analysis also showed mortality disparities between sexes, and geographic locations, races, and ethnicity that warrant targeted public health interventions. Conclusions: Amyloid and HF mortality increased in the recent 22-year period, primarily starting in 2013, emphasizing the urgent need for targeted intervention to address these disparities.

ABSTRACT Background Sodium‐glucose cotransporter 2 inhibitors (SGLT2‐Is) are primarily used to manage type 2 diabetes mellitus (T2DM) and heart failure (HF), but their impact on reducing stroke risk in patients with atrial fibrillation (AF) remains underexplored. We aimed to investigate the impact of SGLT2‐Is for stroke risk mitigation in patients with AF. Methods Using the TriNetX database, we performed a retrospective cohort study on patients ≥ 18 years with AF and on anticoagulation. These patients were then classified into two cohorts based on their use of SGLT2‐Is. To balance the baseline demographics, comorbidities, and medication use, propensity score matching (PSM) was used. The primary outcome was ischemic and hemorrhagic strokes, and the secondary outcomes were all‐cause mortality, all‐cause hospitalizations, need for AF cardioversion or antiarrhythmic drug initiation, and cardiac arrest. Adjusted odds ratio (aORs) and hazard ratios (HRs) were estimated for both the primary and secondary outcomes. Results A total of 152,778 patients with 76,389 patients were included in each cohort (SGLT2‐Is users, and non‐users) after PSM. The mean age of both SGLT2‐Is users and non‐users was 72.8 years. For the SGLT2‐Is users, the mean follow‐up period was 317 days, whereas the mean follow‐up period for the non‐users was 306 days. For the primary outcome, we found that SGLT2‐Is users had a lower risk of ischemic stroke (aOR: 0.889; 95% CI: 0.857–0.923) and hemorrhagic stroke (aOR: 0.682; 95% CI: 0.620–0.749) compared to non‐users. Regarding the secondary outcomes, SGLT2‐Is users also had lower risk for all‐cause mortality (aOR: 0.615; 95% CI: 0.595–0.636), all‐cause hospitalizations (aOR: 0.599; 95% CI: 0.587–0.611), need of AF cardioversion (aOR: 0.846; 95% CI: 0.813–0.881), antiarrhythmic drug initiation (aOR: 0.790; 95% CI: 0.766–0.815), and cardiac arrest (aOR: 0.643; 95% CI: 0.601–0.688). Conclusions SGLT2‐I use in patients with AF is associated with lower risks of stroke and other cardiovascular and non‐cardiovascular outcomes. Future prospective research is needed to validate these findings.

e19524 Background: Carfilzomib, a second-generation proteasome inhibitor, has emerged as one of the therapeutic agents in the treatment of relapsed or refractory multiple myeloma (MM). Despite its known cardiotoxicity, real-world data on its long-term cardiovascular outcomes remain limited. This study aimed to evaluate the real-world cardiovascular outcomes in patients with relapsed or refractory MM treated with carfilzomib. Methods: We utilized the TriNetX network to identify patients (≥18 years old) with relapsed or refractory MM between January 1, 2014, and January 1, 2019. We further categorized the patients into two groups: patients exposed to carfilzomib and patients not exposed to carfilzomib. Inclusion in the carfilzomib group required exposure to carfilzomib during the 5-year study period. Propensity score matching was performed to match these two groups based on comorbidities, medications, baseline hemoglobin A1c, low-density lipoprotein, and left ventricular ejection fraction to produce two comparable cohorts. The study outcomes were cardiovascular outcomes, including acute heart failure, acute myocardial infarction, cerebrovascular accident, acute venous thromboembolism, all-cause hospitalization, and all-cause mortality over the 5-year follow-up duration. Results: A total of 151,802 patients with relapsed or refractory MM were identified, including 6,386 patients (mean age 64.8 ± 10.6 years) who were exposed to carfilzomib and 145,416 patients (mean age 66.1 ± 12.7 years) who were not. After propensity score matching, there were 4,559 (65.3 ± 10.8 years of age, 44.7% female, 18.2% African American [AA]) patients who were exposed to carfilzomib and 4,559 patients who were not (65.2 ± 12.2 years of age, 45.1% female, 17.0% AA). Exposure to carfilzomib was associated with higher odds of acute heart failure (adjusted odds ratio [aOR]: 1.61; 95% CI: 1.48-1.77, P < 0.001), acute myocardial infarction (aOR: 1.24; 95% CI: 1.03-1.48, P = 0.020), cerebrovascular accident (aOR: 1.97; 95% CI: 1.47-2.64, P < 0.001), acute venous thromboembolism (aOR: 1.79; 95% CI: 1.58-2.03, P < 0.001), all-cause hospitalizations (aOR: 1.91; 95% CI: 1.75-2.09, P < 0.001), and all-cause mortality (aOR: 1.97; 95% CI: 1.80-2.16, P < 0.001). Conclusions: Patients with relapsed or refractory MM who were exposed to carfilzomib had poorer cardiovascular outcomes compared to those who did not.

Abstract Aims Sodium-glucose cotransporter 2 inhibitors (SGLT2-Is) improve heart failure (HF) outcomes but their effects on acute myocardial infarction (AMI) remain poorly characterized. This study aimed to evaluate the 1-year cardiovascular outcomes of SGLT2-Is among patients with AMI. Methods and results We conducted an observational, retrospective cohort study using TriNetX data, including patients aged ≥18 with AMI identified via ICD-10 codes regardless of left ventricular ejection fraction (LVEF), categorized by SGLT2-Is use. Propensity score matching (PSM) was performed to balance baseline demographics, comorbidities, and medication use. Adjusted odds ratios (aORs) were estimated for the primary outcome (recurrent AMI) and the secondary outcomes (acute HF hospitalizations, stroke, all-cause hospitalizations, all-cause mortality, new-onset atrial fibrillation, and cardiac arrest). After PSM, 89 554 patients were analysed (44 777 SGLT2-Is users; 44 777 non-users). The mean age was ∼68 years in both cohorts with a similarly high burden of cardiovascular comorbidities. Mean follow-up duration was 290.854 days for SGLT2-Is users and 284.465 days for non-users. SGLT2-Is use was linked to lower rates of recurrent AMI [aOR: 0.459; 95% confidence interval (CI): 0.367–0.551], all-cause hospitalizations (aOR: 0.782; 95% CI: 0.762–0.803), all-cause mortality (aOR: 0.640; 95% CI: 0.612–0.670), and cardiac arrest (aOR: 0.834; 95% CI: 0.773–0.900). No differences were observed in acute HF hospitalizations, new-onset atrial fibrillation, or stroke. Conclusion SGLT2-Is are associated with improved cardiovascular outcomes in patients with AMI, including reductions in recurrent AMI, all-cause hospitalizations and mortality, and cardiac arrest. These findings emphasize the need for prospective clinical trials involving patients with AMI and other cardiovascular comorbidities, regardless of LVEF, to confirm these results.
