BackgroundThis study is aimed at better defining the prevalence of left ventricular dysfunction, atrial fibrillation, and mitral regurgitation in aged patients with cardiogenic acute pulmonary edema.MethodsOne hundred and twenty-three consecutive patients with acute pulmonary edema (APE) arriving at the emergency department of a peripheral hospital who underwent Doppler echocardiography within 36 hours of admission were reviewed retrospectively.ResultsLeft ventricular ejection fraction (LVEF) was normal or near normal (ie, LVEF > or = 40%) in 41.4% (n = 51 patients), and depressed in 58.5% (n = 72). Significant valvular dysfunction was present in 37.4%; mitral regurgitation was the most frequent (22.8%; n = 28). We found a significant positive correlation between systolic blood pressure (SBP) and LVEF (P = 0.003). Within the group of patients presenting with lower SBP (< or = 140 mm Hg), as blood pressure diminished, LVEF also diminished significantly (P = 0.008). In a logistic regression analysis, male sex and SBP of less than 120 mm Hg were found to be the strongest predictors for LVEF < or = 40%, conferring a 2.68- and 2.73-fold risk, respectively (95%CI, 1.19 to -6.00; P = 0.016 and 95%CI, 0.956-7.80; P = 0.061, respectively) compared with female sex and higher SBP groups.ConclusionsThis study emphasizes that emergency departments should have clear-cut policies for diagnosing and treating acute coronary syndromes and tachyarrhythmias, as being potential treatable causes of APE. Once stabilized, patients should be examined for treatable valvular causes. A further study, of acute echocardiography done upon arrival to the emergency department in patients with APE is warranted.
