Abstract:
Objective To explore the clinical features of hypertrophic cardiomyopathy (HCM) in aged patients in China. Methods The 711 patients with HCM in our hospital from Sep 2002 to Sep 2008 were retrospectively reviewed. Clinical data were compared between patients older and younger than 65 years. Results The 103 patients(14.5%) were older than 65 years. Compared with those patients younger than 65 years, the aged patients had a higher prevalence in female (52. 5 vs 29. 0%, P<0. 01), in comorbidity (64. 1% vs 25.0%, P<0, 01)and in atrial fibrillation (21.4% vs 14.0%, P<0. 05). Cardiac insufficiency was the most common symptom in aged patients with HCM. The age(r=0. 213, P<0. 05), size of left atrium (r=0. 308, P<0. 01) and atrial fibrillation (r= 0. 362, P<0. 01) had significant correlation with heart function. The 24 % of patients had one or more major risks for HCM-related sudden cardiac death (SCD), among which syncope was most common. Conclusions A higher prevalence of comorbidity, a higher incidence of atrial fibrillation and worse heart function existed in aged patients with HCM. The major risks for HCM-related SCD should not be neglected in evaluation for aged patients.
