Endothelial Function as a Possible Significant Determinant of Cardiac Function during Exercise in Patients with Structural Heart Disease

Table 1

The summary of cardiopulmonary stress testing.

	Rest	AT	Peak	𝑃-values
				Rest versus AT or Peak
HR (bpm)	72±13	101±12	130±14	<.01
SBP (mmHg)	120±16	133±23	156±22	<.01
DBP (mmHg)	68±10	71±9	74±10	.29
VO2/W(mL * min^-1 * kg^-1)	4.5±2.1	16.3±3.3	24.2±7.5	<.01

Data are presented as the mean value ± standard deviation. HR: heart rate; SBP: systolic blood pressure; DBP: diastolic blood pressure; VO₂/W: oxygen uptake corrected by body weight; AT: anaerobic threshold point; Peak: at peak exercise.
