Samenvatting

Aim: The impact of mitral regurgitation (MR) in patients with advanced heart failure (HF) is poorly known. We aimed to evaluate the impact of MR on clinical outcomes of a real-world, contemporary, multicentre population with advanced HF. 

Methods: The HELP-HF registry enrolled patients with HF and at least one “I NEED HELP” criterion, at four Italian centres between January 2020 and November 2021. The population was stratified by none/mild MR vs. moderate MR vs. severe MR. Outcomes of interest were all-cause, cardiovascular (CV) death, the composite of all-cause death or first HF hospitalization, first HF hospitalization and recurrent HF hospitalizations. 

Results: Among 1079 patients, 429 (39.8%) had none/mild MR, 443 (41.1%) had moderate MR and 207 (19.2%) had severe MR. Patients with severe MR were most likely to be inpatients, present with cardiogenic shock, need intravenous loop diuretics and inotropes/vasopressors, have lower ejection fraction and higher natriuretic peptides. Estimated rates of all-cause death, CV death, and the composite of all-cause death or first HF hospitalization at 1 year increased with increasing MR severity. Compared with no/mild MR, severe MR was independently associated with an increased risk of CV death (adjusted HR 1.61, 95% CI 1.04–2.51, p = 0.033) and recurrent HF hospitalizations (adjusted HR 1.49, 95% CI 1.08–2.06, p = 0.015), but not with and increased risk of all-cause death, first HF hospitalization and composite outcome. 

Conclusions: In unselected patients with advanced HF, severe MR was common and independently associated with an increased risk of CV death and of recurrent HF hospitalizations.
