Type 1 cluster of differentiation 36 deficiency-related cardiomyopathy accelerates heart failure with co-existing mitral valve prolapse: a case report

Free fatty acid is a major energy source in the healthy heart and cluster of differentiation 36 (CD36) partially regulates the rate of myocardial fatty acid uptake. Here, we report a case of CD36 deficiency-related cardiomyopathy with a unique pathophysiology. Heart failure was accelerated by co-existing mitral valve prolapse (MVP) without a distinct phenotype of hypertrophic or dilated cardiomyopathy.A middle-aged man was aware of dyspnoea and...
