Hypertrophic cardiomyopathy (HCM) is a common cardiac genetic disorder with a prevalence of 1/500 and is caused principally by mutations in genes encoding proteins of the cardiac sarcomere (eg, β-cardiac myosin heavy chain and cardiac troponin T).1 Although of substantial scientific importance, HCM is best recognised for being the most common cause of sudden cardiac death (SCD) in the young, especially in young athletes, accounting for up to one-third of all such deaths in the US.2 HCM might be expected to impair exercise capacity, for example through left ventricular hypertrophy (LVH) and diastolic ventricular dysfunction; however, some HCM patients not only tolerate exercise well, but indeed excel athletically. This is surprising given that even HCM patients without LVH exhibit subtle systolic and diastolic abnormalities. Additionally, approximately one-third of HCM patients exhibit abnormal blood pressure (bp) responses during maximal treadmill exercise (ie, a flat blood pressure response, or a fall in
