Mortality in hypertrophic cardiomyopathy – Cardiology MCQ – Answer

Mortality in hypertrophic cardiomyopathy – Cardiology MCQ – Answer Disease specific mortality in hypertrophic cardiomyopathy –  Correct answer: a) 0.5% per year Hypertrophic cardiomyopathy (HCM) is the commonest among heritable heart diseases, with prevalence of about one in 500 individuals [1]. HCM is often highlighted as the leading cause of sudden death in young adults and athletes [2]. Still the absolute annual mortality in HCM is not high with availability of current treatment modalities including the implantation of cardioverter-defibrillator to prevent sudden death. It has been reported to be as low 0.5% per year by Barry J. Maron, the leading authority on hypertrophic cardiomyopathy [3]. After interrogating databases in two HCM referral centers (Minneapolis Heart Institute and Tufts Medical Center), data on 1653 patients between 1992 and 2013 were gathered. Of these 87% had survived at the end of follow up. 72% of the deaths were unrelated to HCM, the predominant cause of death being cancer in older subjects.
