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

Table 2

The summary of the selected parameters obtained from VEST system.

	Rest	AT	Peak	𝑃-values
				Rest versus AT or Peak
EF (%)	54±12	65±16	57±10	<.01
PER (EDV0*sec^-1)	3.1±0.9	3.6±1.0	4.3±0.9	<.01
SVR (mmHg * EDV0^-1 * min^-1)	2.6±0.8	1.3±0.4	1.2±0.2	<.01

Data are presented as the mean value ± standard deviation. EF: ejection fraction; PER: peak ejection ratio; SVR: systemic vascular resistance; AT: anaerobic threshold; Peak: at peak exercise.
