ABSTRACT
Objective To evaluate the alteration of left atrium function during left ventricular geometric remodeling in essential hypertension (EH) with real-time triplane strain rate imaging. Methods Totally 92 patients with EH and 50 healthy volunteers were enrolled. Base on Ganau, patients with EH were divided into 4 groups:normal geometry (A), concentric remodeling (B), concentric hypertrophy (C) and eccentric hypertrophy (D). Systolic peak strain rate (S_(SR)), early diastolic peak strain rate (D_(SR)) and atrium diastolic peak strain rate (A_(SR)) were measured at left atrium walls. Results Compared with normal group, S_(SR) and D_(SR) decreased in group A, B, C and D (P<0.01), A_(SR) increased in group A, B and C (P<0.01), then decreased in group D (P<0.01). Conclusion Left atrium function has changed before LV geometry changes in patients with EH. Real-time triplane strain rate imaging can assess left atrium function and its alteration correctly during left ventricular geometric remodeling in patients with EH.
