[Clinical usefulness of carotid arterial wave intensity in noninvasively assessing left ventricular performance in different hypertensive remodeling hearts].
摘要
OBJECTIVE: To evaluate wave intensity (WI) on left ventricular (LV) performance in the different hypertensive remolding hearts. METHODS: 105 hypertensive and 98 control subjects were underwent noninvasive evaluation of carotid arterial wave intensity, LV structure and function. RESULTS: (1) There were increasing trends in the levels of blood pressure, LV end-diastolic diameter and LV mass index in the control, normal geometry group, concentric remodeling group, concentric and eccentric hypertrophy group. LV ejection fraction increased in the concentric hypertrophy group and decreased in the eccentric hypertrophy group in which mid-wall fractional shortening showed a decreasing trend. LV diastolic filling pressure presented increased progression accompanied by LV remodeling (P < 0.05). (2) Transient acceleration wave intensity (W1) in hypertensive subjects were higher than that in the control (P < 0.05). Transient deceleration wave intensity (W2) was lower than that in the control (P < 0.05). (3) W1 in the concentric hypertrophy group was higher and lower in the eccentric hypertrophy, compared with that in the control group, normal geometry group and concentric remodeling group (P < 0.05). W2 was lower in concentric hypertrophy group and eccentric hypertrophy group than that in the control, normal geometry group and concentric remodeling group (P < 0.05). CONCLUSION: WI is a noninvasively obtained, clinically useful parameter for evaluation of LV performance.
