Abstract: Objective To analyze the clinical characteristics and prognosis of Chinese patients with apical hypertrophic cardiomyopathy (AHCM). Methods A total of 188 patients with AHCM diagnosed at Fuwai Hospital were included in this retrospective study. Clinical characteristics, mortality and cardiovascular morbidity were analyzed. A multiple logistic regression was performed to adjust for potential confounding factors. Results Males predominated with a number of 139 (73.9%) in this cohort. Patient's age ranged from 15 to 81 (51.9 ± 12. 6) years. There were 120 patients (63. 8% ) with "pure" type and 68 patients (36.2%) with "mixed" type of AHCM, 171 patients were followed up for (5.0 ± 3.0)years,cardiovascular mortality was 1.2%, 28 patients (16.4%) experienced one or more cardiovascular events. Conclusion The prevalence of AHCM is high in Chinese HCM patients, pure type AHCM is more common, and AHCM patients have a benign clinical course.
