Objective: A sizeable proportion of patients with secondary mitral regurgitation (SMR) do not receive guideline-directed medical therapy (GDMT) for heart failure (HF). We investigated the association between the use of GDMT and mortality in patients with SMR who underwent transcatheter edge-to-edge repair (TEER)., Methods: We retrospectively analysed patients with SMR and a left ventricular ejection fraction of <50% who underwent TEER at three centres. According to current HF guidelines, GDMT was defined as triple therapy consisting of beta-blockers, renin-angiotensin system (RAS) inhibitors and mineralocorticoid receptor antagonists (MRAs). Patients were divided into two groups: GDMT and non-GDMT groups. We calculated the propensity scores and carried out inverse probability of treatment weighting (IPTW) analyses to compare 2-year mortality between the two groups., Results: Of 463 patients, 228 (49.2%) were treated with GDMT upon discharge. IPTW-adjusted Kaplan-Meier curve showed patients with GDMT had a lower incidence of mortality than those without GDMT (19.8% vs 31.1%, p=0.011). In IPTW-adjusted Cox proportional hazards analysis, GDMT was associated with a reduced risk of 2-year mortality (HR: 0.58; 95% CI: 0.35 to 0.95; p=0.030), which was consistent among clinical subgroups. Moreover, patients with GDMT had a higher rate of left ventricular reverse remodelling at 1 year after TEER than those without GDMT., Conclusion: GDMT, defined as triple therapy consisting of beta-blockers, RAS inhibitors and MRAs, was associated with a reduced risk of 2-year mortality after TEER for SMR. Optimisation of medical therapy is crucial to improve clinical outcomes in patients undergoing TEER for SMR., Competing Interests: Competing interests: RP has received speaker and consultant honoraria from Abbott and Edwards Lifesciences, outside the submitted work.

The progressive nature of heart failure (HF) coupled with high mortality and poor quality-of-life (QoL) mandates greater attention to palliative care (PC) as a routine component of HF management. Limited evidence exists from randomized controlled trials supporting the use of interdisciplinary palliative care in the progressive course of HF. The early palliative care in heart failure trial (EPCHF) is a prospective, controlled, nonblinded, multicenter study of an interdisciplinary palliative care intervention in 200 patients with symptomatic HF characterized by NYHA ≥ 2. The 12-month EPCHF intervention includes monthly consultations by a palliative care team focusing on physical and psychosocial symptom relief, attention to spiritual concerns and advance care planning. The primary endpoint is evaluated by health-related QoL questionnaires after 12 months of treatment. First the functional assessment of chronic illness therapy palliative care (FACIT-Pal) score evaluating QoL living with a chronic disease and second the Kansas City cardiomyopathy questionnaire (KCCQ) measuring QoL living with heart failure will be determined. Secondary endpoints are changes in anxiety/depression (HADS), symptom burden score (MIDOS), spiritual well-being functional assessment of chronic illness therapy spiritual well-being scale (FACIT-Sp), medical resource and cost assessment. EPCHF will help evaluate the efficacy and cost-effectiveness of palliative care in symptomatic HF using a patient-centered outcome as well as clinical and economic endpoints. EPCHF is funded by the Bundesministerium für Bildung und Forschung (BMBF, 01GY17)., (© 2021. The Author(s).)
