[PAPRICA-2 study: Role of precipitating factor of an acute heart failure episode on intermediate term prognosis]

Abstract

Objective: To evaluate the precipitating factors (PF) associated with acute heart failure and their association with medium-term prognosis.

Patients and methods: Multipurpose prospective study from the EAHFE Registry. We included as PF: infection, rapid atrial fibrillation (RAF), anaemia, hypertensive crisis, non-adherence to diet or drug therapy and non-ST-segment-elevation acute coronary syndrome (NSTEACS). Patients without PF were control group. Hazard ratios (HR) crudes and adjusted for reconsultations and mortality at 90 days were calculated.

Results: 3535 patients were included: 28% without and 72% with PF. Patients with RAF (HR 0.67; 95%CI 0.50-0.89) and hypertensive crisis (HR 0.45; 95%CI 0.28-0.72) had less mortality and patients with NSTEACS (HR 1.79; 95%CI 1.19-2.70) had more mortality. Reconsultation was fewer in patients with infection (HR 0.74; 95%CI 0.64-0.85), RAF (HR 0.69; 95%CI 0.58-0.83) and hypertensive crisis (HR 0.71; 95%CI 0.55-0.91). These differences were maintained in all the adjusted models except for hypertensive crisis.

Conclusions: One PF is identified in 3 out of 4 patients and it may influence medium-term prognosis. At 90 days, NSTEACS and RAF were associated with more and less mortality respectively, and RAF and infection with less probability of reconsultation.
