[Prognostic value of prior heart failure in patients admitted with acute pulmonary thromboembolism].
Medicina Clínica 2016 October 22
BACKGROUND AND OBJECTIVE: Pulmonary thromboembolism (PTE) is a very common condition with high mortality. Although some scales include heart failure (HF) as a risk factor of PTE, none of them have assessed the contribution of the different kinds of HF, i. e. with reduced or preserved left ventricular ejection fraction (LVEF) to the in-hospital outcome of patients admitted with PTE.
PATIENTS AND METHOD: A retrospective study assessing a cohort of patients consecutively admitted to hospital with a PTE from 2012-2014. Baseline epidemiological characteristics, treatment during admission and prognostic variables during hospitalization were analyzed. Primary endpoint was defined as hospital mortality for any cause.
RESULTS: A total of 442 patients with PTE were included (88 with prior HF). Patients with a history of HF were older, more frequently had hypertension, diabetes mellitus, chronic kidney or pulmonary disease, cancer, and coronary artery disease, and showed less LVEF (P<.001). Hospital mortality was significantly higher in patients with prior HF (21.6 vs. 6.8%, P<.001). Multivariate analysis found that HF with reduced LVEF but not HF with preserved LVEF resulted as an independent risk factor (respectively OR 5.54; 95% CI 2.12-14.51 and OR 129; 95% CI 0.72-4.44).
CONCLUSIONS: Patients with prior HF admitted to hospital with PTE should be considered a high-risk population, since they present high in-hospital mortality. In our cohort, patients with prior HF and reduced LVEF presented a poorer prognosis than those with preserved LVEF.
