Comparison of Provocative Maneuvers

	Ex vs GDV vs SDV (n = 59)
	EX	SDV	P Value∗	GDV	P Value∗
Mean pLVOTg (mm Hg)	49 (43)	26 (23)	<0.001	33 (29)	<0.001
Mean increment in pLVOTg (mm Hg)	32 (31)	8 (9)	<0.001	15 (16)	<0.001
Reclassified to obstructive HCM	15 (25%)	5 (9%)	0.002	10 (17%)	0.096
Reclassified to severe obstructive HCM	9 (15%)	2 (3%)	0.008	5 (9%)	0.046

EX = exercise; pLVOTg = peak left ventricular outflow tract gradient; other abbreviations as in Table 1.

Values are mean (SD) or n (%).
