PURPOSE: To present an overview of clinical issues related to adults with 
hypertrophic cardiomyopathy (HCM), their presenting symptoms, diagnosis, 
physical examination findings, treatment, and follow-up care.
DATA SOURCES: A comprehensive search of Medline (PubMed) and CINAHL was 
conducted using the key terms HCM, treatment, diagnosis, sudden cardiac death 
(SCD), and complications. This search yielded 21 articles used for this article. 
There were three reference books used for background, diagnosis, and treatment 
information as well.
CONCLUSIONS: Although HCM is the most prevalent genetic disorder affecting the 
heart, it often goes undiagnosed until midlife after patients show symptoms of 
myocardial remodeling. Adults with cardiomyopathy suffer SCD or adverse events 
such as stroke and heart failure from HCM. Early diagnosis will prevent SCD, 
improve quality of life, and slow patient's progression to heart failure.
IMPLICATIONS FOR PRACTICE: Early recognition of HCM in adults by their primary 
care providers will improve patients' quality of life and reduce incidence of 
SCD, heart failure, and stroke.
