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

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.
