Think Beyond Ischemia: Cardiac Arrest in Elderly Hypertrophic Cardiomyopathy

Hypertrophic Cardiomyopathy (HCM) has traditionally been recognized as a condition predominantly affecting younger individuals, often presenting with sudden cardiac death, which left limited treatment options. This misconception has resulted in the underappreciation of HCM in elderly patients, leading to significant implications for timely diagnosis and emergency care. With advancements in cardiovascular medicine, including enhanced imaging technologies, the prevalence of late-onset HCM in the elderly population is increasingly recognized. Recent studies show that a substantial number of elderly patients with HCM present with emergency conditions, including cardiac arrest, emphasizing the need for heightened awareness in this age group. This case report highlights a 68-year-old male with a history of dyslipidemia and ischemic heart disease who suffered an out-of-hospital cardiac arrest while playing badminton. Despite initial resuscitation and treatment for acute coronary syndrome, findings such as left ventricular hypertrophy and systolic anterior motion of the mitral valve raised suspicion of HCM. The patient's condition was confirmed as a potential case of HCM, showcasing the importance of considering this diagnosis in elderly patients presenting with cardiac events. This report underscores the importance of early detection and diagnosis of HCM in older adults, as it can lead to better management, reduced morbidity, and improved quality of life. With increasing use of electrocardiograms and echocardiography, timely identification can significantly reduce hospital visits and prevent disease progression. Through early intervention, the risk of sudden cardiac events can be minimized, ultimately improving patient outcomes in this growing demographic.
