Resum:	To evaluate the precipitating factors for heart failure decompensation in primary care and associations with short-term prognosis. Design Prospective cohort study with a 30-d follow-up from an index consultation. Regression models to determine independent factors associated with hospitalisation or death. Primary care in ten European countries. Patients Patients with diagnosis of heart failure attended in primary care for a heart failure decompensation (increase of dyspnoea, unexplained weight gain or peripheral oedema). Potential precipitating factors for decompensation of heart failure and their association with the event of hospitalisation or mortality 30 d after a decompensation. Of 692 patients 54% were women, mean age 81 (standard deviation [SD] 8. 9) years; mean left ventricular ejection fraction (LVEF) 55% (SD 12%). Most frequently identified heart failure precipitation factors were respiratory infections in 194 patients (28%), non-compliance of dietary recommendations in 184 (27%) and non-compliance with pharmacological treatment in 157 (23%). The two strongest precipitating factors to predict 30 d hospitalisation or death were respiratory infections (odds ratio [OR] 2. 8, 95% confidence interval [CI] (2. 4-3. 4)) and atrial fibrillation (AF) > 110 beats/min (OR 2. 2, CI 1. 5-3. 2). Multivariate analysis confirmed the association between the following variables and hospitalisation/death: In relation to precipitating factors: respiratory infection (OR 1. 19, 95% CI 1. 14-1. 25) and AF with heart rate > 110 beats/min (OR 1. 22, 95% CI 1. 10-1. 35); and regarding patient characteristics: New York Heart Association (NYHA) III or IV (OR 1. 22, 95% CI 1. 15-1. 29); previous hospitalisation (OR 1. 15, 95% CI 1. 11-1. 19); and LVEF < 40% (OR 1. 14, 95% CI 1. 09-1. 19). In primary care, respiratory infections and rapid AF are the most important precipitating factors for hospitalisation and death within 30 d following an episode of heart failure decompensation.
