Background: Despite increased recognition, frailty remains a significant public health challenge. Objective: we aimed to assess the role of education and income, as well as neighborhood socioeconomic status, on physical activity and subsequent frailty in older adults. Methods: Using a population-based cohort of older adults, this study examined the relationship between socioeconomic status (SES) factors, physical activity and frailty. The study included 1,799 participants (mean [SD], 74.6 (6.2), 53.3% female) from the "National Health and Nutrition Survey of Older Adults Aged 65 and Over in Israel", conducted in 2005–2006. A follow-up interview was performed 12–14 years later in a subgroup of 601 subjects (mean [SD], age 84[4]; 56% women). Self-reported leisure-time physical activity (LTPA) was measured at both baseline and follow-up. SES measures were assessed at baseline. Frailty was measured at follow-up, using the Fried's Phenotype Model. Results: All SES measures were strongly and positively associated with LTPA (all p < 0.001). Eighty-two participants (14%) were classified as frail at follow-up. After age and sex adjustment and accounting for attrition bias using inverse probability weighting, baseline LTPA (OR = 2.77, 95% CI: 1.57–4.90, for inactivity; OR = 1.41, 95% CI: 0.75–2.68, for insufficient activity, compared with sufficient activity, P_trend < 0.001) was inversely associated with incident frailty. The association persisted after further adjustment for SES and comorbidity. Conclusion: Among older individuals, multiple SES measures were positively associated with LTPA, which was a strong predictor of lower subsequent frailty risk.

Background: Little is known about the impact of transcatheter mitral valve edge‐to‐edge repair on changes in left ventricular ejection fraction (LVEF) and the effect of an acute reduction in LVEF on prognosis. We aimed to assess changes in LVEF after transcatheter mitral valve edge‐to‐edge repair for both primary and secondary mitral regurgitation (PMR and SMR, respectively), identify rates and predictors of LVEF reduction, and estimate its impact on prognosis. Methods and Results: In this international multicenter registry, patients with both PMR and SMR undergoing transcatheter mitral valve edge‐to‐edge repair were included. We assessed rates of acute LVEF reduction (LVEFR), defined as an acute relative decrease of >15% in LVEF, its impact on all‐cause mortality, major adverse cardiac event (composite end point of all‐cause death, mitral valve surgery, and residual mitral regurgitation grade ≥2), and LVEF at 12 months, as well as predictors for LVEFR. Of 2534 patients included (727 with PMR, and 1807 with SMR), 469 (18.5%) developed LVEFR. Patients with PMR were older (79.0±9.2 versus 71.8±8.9 years; P <0.001) and had higher mean LVEF (54.8±14.0% versus 32.7±10.4%; P <0.001) at baseline. After 6 to 12 months (median, 9.9 months; interquartile range, 7.8–11.9 months), LVEF was significantly lower in patients with PMR (53.0% versus 56.0%; P <0.001) but not in patients with SMR. The 1‐year mortality was higher in patients with PMR with LVEFR (16.9% versus 9.7%; P <0.001) but not in those with SMR ( P =0.236). LVEF at baseline (odds ratio, 1.03 [95% CI, 1.01–1.05]; P =0.002) was predictive of LVEFR for patients with PMR, but not those with SMR ( P =0.092). Conclusions: Reduction in LVEF is not uncommon after transcatheter mitral valve edge‐to‐edge repair and is correlated with worsened prognosis in patients with PMR but not patients with SMR.

Background: Accumulated experience combined with technological advancements in percutaneous coronary interventions (PCI) over the past four decades, has led to a gradual increase in PCI utilization and complexity. We aimed to investigate the temporal trends in PCI complexity and the outcomes of complex PCI (C-PCI) in our institution.Methods: We analyzed 20,301 consecutive PCI procedures performed over a 12-year period. C-PCI was defined as a procedure involving at least one of the following: Chronic total occlusion (CTO), left main (LM), bifurcation or saphenous vein graft (SVG) PCI. Four periods of 3-year time intervals were defined (2008–10, 2011–2013, 2014–2016, 2017–2019), and temporal trends in the rate and outcomes of C-PCI within these intervals were studied. Endpoints included mortality and major adverse cardiac events [MACE: death, acute myocardial infarction (MI), and target vessel revascularization (TVR)] at 1 year.Results: A total of 5,647 (27.8%) C-PCI procedures were performed. The rate of C-PCI has risen significantly since 2,017 (31.2%, p < 0.01), driven mainly by bifurcation and LM interventions (p < 0.01). At 1-year, rates of death, acute MI, TVR and MACE, were all significantly higher in the C-PCI group (8.8 vs. 5.1%, 5.6 vs. 4.5%, 5.5 vs. 4.0%, 17.2 vs. 12.2%, p < 0.001 for all, respectively), as compared to the non-complex group. C-PCI preformed in the latter half of the study period (2014–2019) were associated with improved 1-year TVR (4.4% and 4.8% vs. 6.7% and 7.1%, p = 0.01, respectively) and MACE (13.8% and 13.5% vs. 17.3% and 18.2%, p = 0.001, respectively) rates compared to the earlier period (2007–2013). Death rate had not significantly declined with time.Conclusion: In the current cohort, we have detected a temporal increase in PCI complexity coupled with improved 1-year clinical outcomes in C-PCI.

Current guidelines support the use of transcatheter edge-to-edge repair (TEER) for patients with both primary and secondary mitral regurgitation. We aimed to compare the prognoses of TEER in degenerative mitral regurgitation (DMR) vs. functional mitral regurgitation (FMR). A total of 208 consecutive patients who underwent TEER over a ten-year period were analyzed. Primary endpoints included rates of all-cause death and major adverse cardiac events (MACE: composite of all-cause death, hospitalizations for heart failure, mitral valve surgery, or TEER re-intervention). A total of 148 (71%) patients were identified with FMR, while 60 (29%) were identified with DMR. Patients in the FMR group were younger (77.2 ± 8.4 vs. 80.2 ± 7.2, p = 0.02), suffered more frequently from coronary artery disease (54.1% vs. 10.0%, p = 0.02), and atrial fibrillation/flutter (70.9% vs. 38.3%, p = 0.02). Rates of 1-year death (21.6% vs. 10.0%, p = 0.03) and MACE (41.2% vs. 21.7%, p = 0.02) were higher for the FMR group, as compared to the DMR group. After correcting for variables, FMR independently predicted rates of MACE (HR-1.78, 95% CI 1.23–2.48, p = 0.04) and had a non-significant effect on one-year mortality (HR-1.67, 95%CI 0.98–3.74, p = 0.07). In our experience, worse overall 1-year composite MACE outcomes were observed after TEER in patients with FMR as compared to patients with DMR.

Aims: Despite recent progress in coronary artery disease treatment, ST-segment elevation myocardial infarction (STEMI) remains a very high-risk medical condition. Whether recent patients’ outcomes, following implementation of the 2012 European Society of Cardiology (ESC) STEMI guidelines have improved, is yet unclear. Methods and results: The study was based on a prospective detailed registry of 2004 consecutive patients with STEMI treated with primary percutaneous coronary intervention (pPCI). We compared trends during two different time periods (2006–2012 vs. 2012–2018). Endpoints included mortality and major adverse cardiac events (MACE: death, repeat myocardial infarction, target vessel revascularization and coronary artery bypass surgery) at 1 month, 1 and 2 years. Rates of transradial interventions have risen significantly (67.3 vs. 42.0%; P < 0.01), as have rates of prasugrel administration (69.8 vs. 4.5%; P < 0.01) and use of drug eluting stents (75.5 vs. 56.5%; P < 0.01). Both at 1 and at 2 years, MACE was significantly lower in the later period (11.6 vs. 20.9%; P < 0.01 and 18.9 vs. 25.4%; P < 0.01 respectively), whereas mortality was only significantly lower after 1 year (5.8 vs. 8.6%; P = 0.02). Cox regression identified the later period (2012–2018) to independently and favorably impact MACE (hazard ratio, −0.69; 95% CI, 0.56–0.85; P < 0.01) but not mortality (hazard ratio, −0.76; 95% CI, 0.54–1.05; P = 0.09). Conclusion: Among patients treated with pPCI for STEMI, adoption of the contemporary evidence-based treatments is associated with better MACE derived outcomes, following the inception of the 2012 ESC guidelines. Nonetheless, the long-term mortality was marginally (but not significantly) lower, which indicates an unmet need for further improvement.
