摘要

Abstract

Objective

To study the differences of cardiovascular system between men and women in response to exercise stress.

Methods

Forty healthy youth were tested according to Bruce protocol of exercise stress. They were detected by ultrasonography during the rest

peak exercise

and recovery stages

respectively. The left ventricular diastolic elastance (Ed)

effective arterial elastance (Ea)

left ventricular end-systolic elatance (Ees)

ventricular-vascular coupling index (VVI)

and total stiffness index (TSI) were measured and calculated according to the formulas. The results of all stages were compared according to genders.

Results

All stages

the Ed

TSI

and VVI of women were higher than those of men

but the Ees was lower than that of men (all

0.05); there was no significant difference in Ea between men and women. The Ed

Ees

and TSI were closely related with left ventricular oxygen consumption and heart function

and women showed more closely. Before and after exercise

the changes were different in Ed

Ees

TSI

and VVI (all

0.05)

and VVI changed least.

Conclusions

Before and after exercise

the ventricular stiffness matched well with arterial stiffness and maintained within a narrow range. For women

the tolerance of exercise was lower than that of men.
