Avoid Atrial Fibrillation in Patients with Hypertrophic Cardiomyopathy

摘要

In a large database of hypertrophic cardiomyopathy patients, the clinical profile and prognostic significance of atrial fibrillation was assessed. Over a 3-year time period, patients were recruited from a large Chinese hospital; see Tian et al. [1] in the latest issue of Cardiology. Of 654 hypertrophic cardiomyopathy patients, atrial fibrillation was documented in 24% of these patients at some time either during the initial evaluation or during follow-up with a mean of 4.2 years. The occurrence of atrial fibrillation was associated with increased risk for all-cause mortality, cardiovascular mortality, heart failure and ischemic stroke. Multivariate analysis showed that atrial fibrillation was an independent predictor of stroke-related death, heart failure and ischemic stroke.
