RESUMO
BACKGROUND: Transcatheter aortic valve replacement (TAVR) is the most common treatment in patients with symptomatic severe aortic stenosis (AS). As concomitant coronary artery disease is common in AS patients, access to the coronary arteries following TAVR is of increasing importance. OBJECTIVES: This study evaluated the incidence and risk factors for unplanned coronary angiography following TAVR and, using fluoroscopic time as a surrogate, analyzed the complexity of coronary artery cannulation. METHODS: All patients who underwent TAVR in Sweden between 2008 and 2022 were identified using the SWEDEHEART registry. The cumulative incidence of coronary angiography after TAVR was analyzed with mortality as a competing risk. Angiography and PCI complexity were analyzed using fluoroscopic time and compared across different transcatheter heart valve designs. RESULTS: Out of 9806 patients, 566 subsequently required coronary angiography. The incidence was highest for three-vessel and/or left main disease. Younger age, the extent of prior coronary artery disease, and peripheral vascular disease were associated with an increased risk of coronary angiography. Fluoroscopy time was increased in TAVR patients compared to the control group with the longest fluoroscopy times observed in cases involving supra-annular and self-expanding valves. CONCLUSIONS: The incidence of coronary angiography following TAVR is still low. Younger patients and patients with concomitant coronary artery disease have a higher risk. Procedural time is longer in patients with a previous THV replacement. As TAVR is emerging as the first-line treatment in patients with longer life expectancy, facilitating coronary access is an important factor when considering which THV device to implant.

The prevalence of HF with preserved ejection raction (HFpEF, with EF ≥50%) is increasing across all populations with high rates of hospitalization and mortality, reaching up to 80% and 50%, respectively, within a 5-year timeframe. Comorbidity-driven systemic inflammation is thought to cause coronary microvascular dysfunction and increased epicardial adipose tissue, leading to downstream friborsis and molecular changes in the cardiomyocyte, leading to increased stiffness and diastolic dynsfunction. HFpEF poses unique challenges in terms of diagnosis due to its complex and diverse nature. The diagnosis of HFpEF relies on a combination of clinical assessment, imaging studies, and biomarkers. An additional important step in diagnosing HFpEF involves excluding certain cardiac diagnoses that may be specific underlying causes of HFpEF or may be masquerading as HFpEF and require specific alternative treatment approaches. In addition to administering sodium-glucose cotransporter 2 inhibitors to all patients, the most effective approach to enhance clinical outcomes may involve tailored therapy based on each patient's unique clinical profile. Exercise should be recommended for all patients to improve the quality of life. Glucagon-like peptide-1 1 agonists are a promising treatment option in obese HFpEF patients. Novel approaches targeting inflammation are also in early phase trials.

The frequency and effectiveness of repeat mitral valve interventions (RMVI) after transcatheter edge-to-edge repair (TEER) for secondary mitral regurgitation (MR) are unknown. We aimed to examine the rate of and outcomes after RMVI after TEER in the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) trial. Only 3.9% of COAPT trial patients required a repeat mitral valve intervention during 4-year follow-up which was successful in 90% of cases but was associated with an increased rate of heart failure (HF) hospitalizations (HFH). The COAPT trial randomized HF patients with severe secondary MR to TEER with the MitraClip device plus guideline-directed medical therapy (GDMT) versus GDMT alone. We evaluated the characteristics and outcomes of patients who had an RMVI during 4-year follow-up. A MitraClip implant was attempted in 293 patients randomized to TEER+GDMT, 10 of whom underwent an RMVI procedure (9 repeat TEER and 1 surgical mitral valve replacement) after 4 years of follow-up (cumulative incidence 3.90%, 95% confidence interval [CI] 2.08 to 7.08; median 182 days after the initial procedure). Patients with RMVI had larger mitral annular diameters, fewer clips implanted, and were more likely to have ≥3+MR at discharge compared with those without RMVI. Reasons for RMVI included failed index procedure because of difficult transseptal puncture (n = 2) or tamponade (n = 1); residual or recurrent severe MR after an initially successful procedure (n = 5); partial clip detachment (n = 1); and site-assessed mitral stenosis (n = 1). RMVI was successful in 8/10 (80%) patients. Patients who underwent RMVI had higher 4-year rates of HFH but similar mortality compared with those without RMVI. The annualized incidence rates of all HFH in patients who underwent RMVI were 234 events per 100 person-years (95% CI 139 to 395) pre-RMVI and 46 per 100 person-years (95% CI 25 to 86) post-RMVI as compared with 32 events per 100 patient-years (95% CI 28 to 36) in patients without RMVI. The rate ratio of HFH was reduced after RMVI in patients who underwent RMVI (0.20, 95% CI 0.09 to 0.45). In conclusion, the cumulative incidence of RMVI after 4 years was 3.9% in patients who underwent TEER for severe secondary MR in the COAPT trial. Patients who underwent RMVI were at increased risk of HFH which was reduced after the RMVI procedure.

AIM: To assess cause-specific death in patients with heart failure with preserved, mildly reduced, and reduced ejection fraction (HFpEF, HFmrEF, and HFrEF). METHODS AND RESULTS: Data were analysed from the Swedish Heart Failure Registry (SwedeHF) and the National Patient Register of patients enrolled in SwedeHF 2000-2021. Cox proportional hazards regression models were performed and adjusted for age, sex and time period. Among 100 584 patients (23% HFpEF, 23% HFmrEF, 53% HFrEF), median age (interquartile range) was 75 (66-82) and 36% were female. Of those who died within 5 years, most deaths were ascribed to cardiovascular (CV) causes across all ejection fraction (EF) categories. Within 5 years, HFpEF had higher adjusted risk of non-CV death (hazard ratio [HR] 1.33, 95% confidence interval [CI] 1.28-1.38, p < 0.001) and lower adjusted risk of CV death (HR 0.85, 95% CI 0.82-0.88, p < 0.001) compared to HFrEF. Ischaemic heart disease (IHD) and cancer were the most common causes of CV and non-CV death regardless of EF category. The incidence rate of CV death due to IHD was highest in HFrEF while incidence rates of CV death due to pulmonary vascular disease, stroke, valvular heart disease and atrial fibrillation increased with increasing EF. The incidence rates of non-CV deaths due to cancer, respiratory disease, and infections increased with increasing EF. CONCLUSION: Cardiovascular death was more common than non-CV death across all EF categories although the risk of non-CV death within 5 years was higher with increasing EF. IHD and cancer were the most common causes of CV and non-CV deaths, respectively, regardless of EF category.

BACKGROUND: The frequency of and relationship between hospital readmissions and outcomes after revascularization for left main coronary artery disease (LMCAD) are unknown. OBJECTIVES: The purpose of this study was to study the incidence, predictors, and clinical impact of readmissions following percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for LMCAD. METHODS: In the EXCEL (XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial, 1,905 patients with LMCAD were randomized to PCI vs CABG. The cumulative incidence of readmissions was analyzed with multivariable Anderson-Gill and joint frailty models to account for recurrent events and the competing risk of death. The impact of readmission on subsequent mortality within 5-year follow-up was determined in a time-adjusted Cox proportional hazards model. RESULTS: Within 5 years, 1,868 readmissions occurred in 851 of 1,882 (45.2%) hospital survivors (2.2 ± 1.9 per patient with readmission[s], range 1-16), approximately one-half for cardiovascular causes and one-half for noncardiovascular causes (927 [49.6%] and 941 [50.4%], respectively). One or more readmissions occurred in 463 of 942 (48.6%) PCI patients vs 388 of 940 (41.8%) CABG patients (P = 0.003). After multivariable adjustment, PCI remained an independent predictor of readmission (adjusted HR: 1.22; 95% CI: 1.10-1.35; P < 0.0001), along with female sex, comorbidities, and the extent of CAD. Readmission was independently associated with subsequent all-cause death, with interaction testing indicating a higher risk after PCI than CABG (adjusted HR: 5.72; 95% CI: 3.42-9.55 vs adjusted HR: 2.72; 95% CI: 1.64-4.88, respectively; Pint = 0.03). CONCLUSIONS: In the EXCEL trial, readmissions during 5-year follow-up after revascularization for LMCAD were common and more frequent after PCI than CABG. Readmissions were associated with an increased risk of all-cause death, more so after PCI than with CABG.

BACKGROUND: Cholinesterase inhibitors (ChEIs) are the first-line symptomatic pharmacologic treatment for patients with mild-to-moderate Alzheimer's disease (AD). Although the target organ for this group of drugs is the brain, inhibition of the enzyme may affect cardiac function through vagotonic and anti-inflammatory effects. OBJECTIVE: To assess the impact of ChEIs on outcomes in patients with AD who have experienced myocardial infarction (MI) prior to the AD diagnosis. METHODS: Patients who had experienced MI before they were diagnosed with AD or Alzheimer's mixed dementia between 2008 and 2018 were identified from the Swedish Dementia Registry (SveDem, www.svedem.se), which was linked to the National Patient Registry to obtain data on MI and mortality. Cox proportional hazards regression model among a propensity score-matched dataset was performed to assess the association between ChEI treatment and clinical outcomes. RESULTS: Of 3198 patients with previous MI and a diagnosis of AD or mixed dementia, 1705 (53%) were on treatment with ChEIs. Patients treated with ChEIs were more likely to be younger and have a better overall cardiovascular (CV) risk profile. The incidence rate of all-cause death (per 1000 patient-years) in the propensity-matched cohort of 1016 ChEI users and 1016 non-users was 168.6 in patients on treatment with ChEIs compared with 190.7 in patients not on treatment with ChEIs. In this propensity-matched cohort, treatment with ChEIs was associated with a significantly lower risk of all-cause death (adjusted hazard ratio 0.81, 95% confidence interval 0.71-0.92) and a greater reduction with higher doses of ChEIs. While in the unadjusted analysis, ChEIs were associated with a lower risk of both CV and non-CV death, only the association with non-CV death remained significant after accounting for baseline differences. CONCLUSION: Treatment with ChEIs was associated with a significantly reduced risk of all-cause death, driven by lower rates of non-CV death in a nationwide cohort of patients with previous MI and a diagnosis of AD or mixed dementia. These associations were greater with higher ChEI doses. CONDENSED ABSTRACT: We assessed the association between cholinesterase inhibitors (ChEIs) and clinical outcomes in a nationwide cohort of patients with previous myocardial infarction (MI) and a diagnosis of Alzheimer's disease (AD) or mixed dementi. In propensity-matched analysis, treatment with ChEIs was associated with a 19% reduction in all-cause death driven by non-cardiovascular death. The reduction in all-cause death was greater with the higher doses of ChEIs.
