Abstract

V originále

Methods and results A total of 178 highly symptomatic, consecutive patients (58 +/- 12 years, 53% women) were treated by ASA between April 1998 and April 2013 and followed-up for 4.8 years (IQR 2.1-7.5). At baseline, 155 patients (87%) suffered from dyspnoea >= 3 class of NYHA; at the most recent examination, 87 patients (49%) and 23 patients (13%) reported dyspnoea of NYHA class 1 and >= 3, respectively. The left ventricular outflow gradient was significantly reduced (68 +/- 42 vs. 20 +/- 25 mmHg; P < 0.01). A total of 19 deaths (11%) occurred during 925 patient-years, which means an overall mortality rate of 2.1% per year. Survival free of all-cause mortality at 1, 5, and 10 years was 97% (95% CI, 93-99%), 92% (95% CI, 87-96%), and 82% (95% CI, 70-90%), respectively. This observed mortality was comparable to the expected survival for age- and sex-comparable general population (P = 0.34). According to multivariate analysis, the only independent predictor of all-cause mortality was age at ASA (hazard ratio 1.09, 95% CI 1.04-1.14; P < 0.01). Conclusions This study suggests that in patients with HOCM and important symptoms who underwent ASA, long-term survival after the procedure did not differ significantly from that of the general population.
