Does blood pressure response during exercise predict risk in young patients with hypertrophic cardiomyopathy?
Exercise blood pressure response is a useful initial prognostic tool in young patients with HCM, but abnormal responses require further risk stratification due to low positive predictive accuracy.
A normal exercise blood pressure response identifies low-risk young patients with HCM. An ABPR identifies the high-risk cohort; the low positive predictive accuracy, however, indicates that further risk stratification is warranted.
