Rationale and design of the effect of evolocumab in patients at high cardiovascular risk without prior myocardial infarction or stroke (VESALIUS-CV) trial.

BACKGROUND: The reduction of low-density lipoprotein cholesterol (LDL-C) with evolocumab, a fully human monoclonal antibody inhibitor of proprotein convertase subtilisin/kexin type 9 (PCSK9i), reduces the risk of major adverse cardiovascular events in patients with established atherosclerotic cardiovascular disease (ASCVD) with a prior MI, prior stroke, or symptomatic peripheral artery disease, with no offsetting safety concerns. The effect of evolocumab on CV outcomes in lower risk patients without a history of MI or stroke has not been explored. STUDY DESIGN: VESALIUS-CV is a randomized, double-blind, placebo-controlled, global clinical trial designed to evaluate the effect of evolocumab on the risk of major cardiovascular events in patients at high cardiovascular risk but without a prior ischemic event. The study population consists of 12,301 patients with atherosclerosis or high-risk diabetes mellitus without a prior MI or stroke; an LDL-C ≥ 90 mg/dL, or non-high-density lipoprotein cholesterol (non-HDL-C) ≥ 120 mg/dL, or apolipoprotein B ≥ 80 mg/dL; and treated with optimized lipid-lowering therapy. Patients were randomized in a 1:1 ratio to evolocumab 140 mg subcutaneously every 2 weeks or matching placebo. The primary efficacy objective is to assess whether evolocumab reduces the risk of the dual primary composite endpoints of coronary heart disease (CHD) death, myocardial infarction (MI), or ischemic stroke (triple primary endpoint) and of CHD death, MI, ischemic stroke, or ischemia-driven arterial revascularization (quadruple primary endpoint). Recruitment began in June 2019 and completed in November 2021. The trial is planned to continue until at least 751 patients experience an adjudicated triple endpoint, at least 1254 experience an adjudicated quadruple endpoint, and the median follow-up is ≥4.5 years. CONCLUSION: VESALIUS-CV will determine whether the addition of evolocumab to optimized lipid-lowering therapy reduces cardiovascular events in patients at high cardiovascular risk without a prior MI or stroke.

Echocardiographic and clinical features of patients developing prosthesis-patient mismatch after transcatheter aortic valve replacement: Insights from the Recovery-TAVR registry.

BACKGROUND: The impact of prosthesis-patient mismatch (PPM) on major endpoints after transcatheter aortic valve replacement (TAVR) is controversial and the effects on progression of heart damage are poorly investigated. Therefore, our study aims to evaluate the prevalence and predictors of PPM in a "real world" cohort of patients at intermediate and low surgical risk, its impact on mortality and the clinical-echocardiographic progression of heart damage. METHODS: 963 patients who underwent TAVR procedure between 2017 and 2021, from the RECOVERY-TAVR international multicenter observational registry, were included in this analysis. Multiparametric echocardiographic data of these patients were analyzed at 1-year follow-up (FU). Clinical and echocardiographic features were stratified by presence of PPM and PPM severity, as per the most current international recommendations, using VARC-3 criteria. RESULTS: 18% of patients developed post-TAVR. PPM, and 7.7% of the whole cohort had severe PPM. At baseline, 50.3% of patients with PPM were male (vs 46.2% in the cohort without PPM, P = .33), aged 82 (IQR 79-85y) years vs 82 (IQR 78-86 P = .46), and 55.6% had Balloon-Expandable valves implanted (vs 46.8% of patients without PPM, P = .04); they had smaller left ventricular outflow tract (LVOT) diameter (20 mm, IQR 19-21 vs 20 mm, IQR 20-22, P = .02), reduced SVi (34.2 vs 38 mL/m2, P < .01) and transaortic flow rate (190.6 vs 211 mL/s, P < .01). At predischarge FU patients with PPM had more paravalvular aortic regurgitation (moderate-severe AR 15.8% vs 9.2%, P < .01). At 1-year FU, maladaptive alterations of left ventricular parameters were found in patients with PPM, with a significant increase in end-systolic diameter (33 mm vs 28 mm, P = .03) and a significant increase in left ventricle end systolic indexed volume in those with moderate and severe PPM (52 IQR 42-64 and 52, IQR 41-64 vs 44 IQR 35-59 in those without, P = .02)). No evidence of a significant impact of PPM on overall (P = .71) and CV (P = .70) mortality was observed. Patients with moderate/severe PPM had worse NYHA functional class at 1 year (NYHA III-IV 13% vs 7.8%, P = .03). Prosthesis size≤23 mm (OR 11.6, 1.68-80.1) was an independent predictor of PPM, while SVi (OR 0.87, 0.83-0.91, P < .001) and LVOT diameter (OR 0.79, 0.65-0.95, P = .01) had protective effect. CONCLUSIONS: PPM was observed in 18% of patients undergoing TAVR. Echocardiographic evaluations demonstrated a PPM-related pattern of early ventricular maladaptive alterations, possibly precursor to a reduction in cardiac function, associated with a significant deterioration in NYHA class at 1 year. These findings emphasize the importance of prevention of PPM of any grade in patients undergoing TAVR procedure, especially in populations at risk.

Long-Term Efficacy of Evolocumab in Patients With or Without Multivessel Coronary Disease.

BACKGROUND: In FOURIER (Further Cardiovascular Outcomes Research with PCSK9 Inhibition in Subjects with Elevated Risk), during a median follow-up of 2.2 years, risk reduction for major adverse cardiovascular event with evolocumab was greater in patients with multivessel disease (MVD). The FOURIER Open-Label Extension (FOURIER-OLE) provides an additional median follow-up of 5 years. OBJECTIVES: The purpose of this study was to assess the long-term benefit of evolocumab in patients with and without MVD. METHODS: FOURIER randomized 27,564 patients to evolocumab vs placebo; 6,635 entered FOURIER-OLE. Patients with coronary artery disease were categorized based on the presence of MVD (≥40% stenosis in ≥2 large vessels). The primary endpoint was cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization; the key secondary endpoint was cardiovascular death, myocardial infarction, or stroke. RESULTS: Of 23,656 patients in FOURIER with coronary artery disease, 25.4% had MVD; 5,887 patients continued into FOURIER-OLE. The risk reduction with initial allocation to evolocumab tended to be greater in patients with MVD than in those without: 23% (HR: 0.77 [95% CI: 0.68-0.87]) vs 11% (HR: 0.89 [95% CI: 0.82-0.96]) for the primary and 31% (HR: 0.69 [95% CI: 0.59-0.81]) vs 15% (HR: 0.85 [95% CI: 0.77-0.94]) for the key secondary endpoints (Pinteraction = 0.062 and Pinteraction = 0.031, respectively). The magnitude of benefit tended to grow during the first several years, reaching 37% to 38% reductions in risk in patients with MVD and 23% to 28% reductions in risk in patients without MVD. CONCLUSIONS: Evolocumab reduced the rate of major adverse cardiovascular event in patients with and without MVD. The benefit tended to occur earlier and was larger in patients with MVD. However, the magnitude grew over time in both groups. These data support early initiation of intensive low-density lipoprotein cholesterol lowering both in patients with and without MVD.

OPTImal PHARMacological therapy for patients with heart failure: Rationale and design of the OPTIPHARM-HF registry.

AIMS: Patients with heart failure (HF) remain often undertreated for multiple reasons, including treatment inertia, contraindications, and intolerance. The OPTIimal PHARMacological therapy for patients with Heart Failure (OPTIPHARM-HF) registry is designed to evaluate the prevalence of evidence-based medical treatment prescription and titration, as well as the causes of its underuse, in a broad real-world population of consecutive patients with HF across the whole ejection fraction spectrum and among different clinical phenotypes. METHODS: The OPTIPHARM-HF registry (NCT06192524) is a prospective, multicenter, observational, national study of adult patients with symptomatic HF, as defined by current international guidelines, regardless of ejection fraction. Both outpatients and inpatients with chronic and acute decompensated HF will be recruited. The study will enroll up to 2500 patients with chronic HF at approximately 35 Italian HF centres. Patients will be followed for a maximum duration of 24 months. The primary objective of the OPTIPHARM-HF registry is to assess prescription and adherence to evidence-based guideline-directed medical therapy (GDMT) in patients with HF. The primary outcome is to describe the prevalence of GDMT use according to target guideline recommendation. Secondary objectives include implementation of comorbidity treatment, evaluation of sequence of treatment introduction and up-titration, description of GDMT implementation in the specific HF population, main causes of GDMT underuse, and assessment of cumulative rate of cardiovascular events. CONCLUSION: The OPTIPHARM-HF registry will provide important implications for improving patient care and adoption of recommended medical therapy into clinical practice among HF patients.
