Exercise hypotension occurs in one-third of HCM patients and associates with younger age plus family sudden death history; leaves open its prognostic role.
What is the incidence of abnormal blood pressure responses during exercise in patients with hypertrophic cardiomyopathy, and how do these responses correlate with clinical risk factors?
Abnormal blood pressure responses during exercise are common in hypertrophic cardiomyopathy and are associated with younger age and a family history of sudden death, suggesting a potential link to hemodynamic instability.
Frenneaux et al. (1990) studied this question.
