[Different patterns of the left ventricle of heart in hypertensive patients].

Abstract

Objective: To observe the clinical characteristics of different patterns of the left ventricule in hypertensive patients.

Methods: Echocardiography was used in 228 essential hyventricule of heart in hypertensive patients and 60 healthy individuals.

Results: In the hypertensive group, the rate of normal left ventricle, concentric remodeling, concentric hypertrophy and eccentric hypertrophy were 21.9%, 36.4%, 32.9% and 8.8%, respectively. The aortic root dimension and left atrial dimension were higher in the hypertensive group than those in the normal group (P < 0.05), especially for concentric hypertrophy and eccentric hypertrophy. Cardiac index and stroke volume index in eccentric hypertrophy were higher than those in the normal group and concentric remodeling (P < 0.05). Ejection fraction and fractional shortening in concentric remodeling were the highest and ejection fraction in eccentric hypertrophy was the lowest among all patterns (P < 0.05). E/A rate was lower in the hypertensive group than in the normal group (P < 0.05), especially for concentric hypertrophy and eccentric hypertrophy. The total peripheral resistance was the highest in concentric remodeling and the lowest in eccentric hypertrophy (P < 0.05).

Conclusion: Different patterns in the left ventricle have their own characteristics and patients should be treated differently according to the patterns.
