Older patients (≥60 years) with HCM have a low risk of disease-related mortality, suggesting that aggressive prophylactic defibrillator implantation may not be warranted in this population.
HCM patients surviving into the seventh decade of life are at low risk for disease-related morbidity/mortality, including sudden death, even with conventional risk factors. These data do not support aggressive prophylactic defibrillator implantation at advanced ages in HCM. Other cardiac or noncardiac comorbidities have a greater impact on survival than HCM in older patients.
