Impaired venoconstriction associates with syncope and exercise hypotension in HCM; hypothesis-generating and should not yet change practice.
Do patients with hypertrophic cardiomyopathy have impaired reflex venoconstriction related to syncope or exercise hypotension?
Abnormal reflex control of venous capacitance beds in patients with hypertrophic cardiomyopathy is associated with both syncope and exercise hypotension.
Thomson et al. (1998) studied this question.
