Tako-tsubo Syndrome and Heart Failure: Long-term Follow-up

Tako-tsubo syndrome produces a variable degree of transient left ventricular dysfunction. Our objective was to determine the short- and long-term prognosis of this syndrome, the incidence of and risk factors for the development of heart failure, and the influence on heart failure on the long-term ou...

Description
Summary:Tako-tsubo syndrome produces a variable degree of transient left ventricular dysfunction. Our objective was to determine the short- and long-term prognosis of this syndrome, the incidence of and risk factors for the development of heart failure, and the influence on heart failure on the long-term outcome in our patient population. We prospectively recorded the clinical features and events during the hospital stay and follow-up of 100 patients with tako-tsubo syndrome. The risk factors for heart failure during hospital stay, considered as Killip class≥II, were assessed. Most of the patients were women (89%), with a mean age of 68 years. The distribution according to Killip class was: Killip I, 70 patients; Killip II, 15; Killip III, 5; and Killip IV, 10. Cardiovascular risk factors, including diabetes, were common in the overall group, but were more so in the heart failure cohort. The left ventricular ejection fraction was lower in the heart failure group (51% vs 42%; P
