ABSTRACT

Objective: The purpose of this study was mainly to determine the midterm outcome of septal myectomy (SM) and medical therapy (MT) in mildly symptomatic patients (NYHA class II) with hypertrophic obstructive cardiomyopathy (HOCM). Methods: The study cohort consisted of 184 mildly symptomatic patients with HOCM evaluated in Beijing Anzhen Hospital, Capital Medical University between March 2001 and December 2017, including 82 patients in the SM group and 102 patients in the MT group. Overall survival and HCM-related survival were mainly observed. Results: The average follow-up time was 5.0 years. Compared to patients accepting MT, patients treated with SM were associated with comparable overall survival (96.5% and 93.1% vs. 92.9% and 83.0% at 5 and 10 years, respectively; P = 0.197) and HCM-related survival (98.7% and 98.7% vs. 94.2% and 86.1% at 5 and 10 years, respectively; P = 0.063). However, compared to MT, SM was superior at improvement of NYHA class (1.3 ± 0.6 vs. 2.1 ± 0.5, P < 0.001) and mean reduction of resting left ventricular outflow (LVOT) gradient (78.5 ± 18.6% vs. 28.3 ± 18.4%, P < 0.001). Multivariate analysis suggested that resting LVOT gradient in the last clinical examination was an independent predictor of all-cause mortality (HR = 1.017, 95%CI: 1.000-1.034, P = 0.045) and HCM-related mortality (HR = 1.024, 95%CI: 1.005-1.043, P = 0.012) in the entire cohort. Conclusion: Compared with MT, SM had comparable overall survival and HCM-related survival in mildly symptomatic HOCM patients, but SM had advantages on improving clinical symptoms and reducing resting LVOT gradient. Resting LVOT gradient in the last clinical examination was an independent predictor of all-cause mortality and HCM-related mortality.

ABSTRACT

OBJECTIVE: The aim of this study was primarily to determine efficacy after alcohol septal ablation (ASA) in mildly symptomatic patients (NYHA class II) with hypertrophic obstructive cardiomyopathy (HOCM), as compared to medical therapy. METHODS: This retrospective study included 163 mildly symptomatic patients with HOCM evaluated in Beijing Anzhen Hospital between March 2001 and August 2019, consisting of the medical group (n = 105) and the ASA group (n = 58). All-cause mortality and HCM-related death were mainly observed. RESULTS: Follow-up was completed in 161 patients and the median follow-up was 6.0 years. Compared to medically treated patients, patients post-ASA had comparable survival free of all-cause mortality (98.3% and 95.1% vs. 93.0% and 83.1% at 5 and 10 years, respectively; p = 0.374). Survival free of HCM-related death was also similar between ASA and medical groups (98.3% and 95.1% vs. 94.3% and 86.2% at 5 and 10 years, respectively; p = 0.608). However, compared to medical therapy, ASA had advantages on the improvement of NYHA class (1.4 ± 0.6 vs. 2.1 ± 0.5, p = .000) and lower occurrence of new-onset atrial fibrillation (AF) (7.8% vs. 20.4%, p = .048). Multivariate analysis demonstrated that resting LVOT gradient at the last clinical check-up was an independent predictor of all-cause mortality (HR = 1.021, 95%CI 1.002-1.040, p = .027). CONCLUSION: This registry suggests that mildly symptomatic patients with HOCM treated with ASA have comparable survival to that of medically treated patients, with the improvement of NYHA class and lower occurrence of new-onset AF. All-cause mortality is independently associated with resting LVOT gradient at the last clinical check-up.
