摘要

Objectives: The purpose of this study was to describe the clinical course and risk stratify older patients with hypertrophic cardiomyopathy (HCM) who were more than 60 years of age.Background: Two major problems associated with HCM are risk for sudden death and disease progression. These are relatively well denned in young patients. Whether patients of more advanced age harbor similar risks is unresolved and often creates clinical dilemmas, particularly in decisions for primary prevention of sudden death with implantable denbrillators.Methods: Patients for this study were selected from databases of 2 large HCM centers in USA. Consecutively presenting patients with HCM, who were >60 years of age at first presentation to these centers were selected for this study. These patients were followed up by hospital visit or telephone contact.
