Prevalence and Predictor Analysis of Left Ventricular Reverse Remodeling in Patients With Primary Hypertension Combining Left Ventricular Systolic Dysfunction / 中国循环杂志

ABSTRACT

Objective: To analyze the prevalence and predictor for left ventricular reverse remodeling (LVRR) in patients of primary hypertension combining left ventricular systolic dysfunction (LVSD) with tailored medication. Methods: A total of 118 consecutive patients admitted in our unit from 2010-08 to 2012-10 with the base line left ventricular ejection fraction (LVEF)≤40%were enrolled. The demographic and clinical information with the findings of echocardiography at admission were collected. The patients were followed-up until 2013-12 or until the all cause death/cardiac transplantation. According to echocardiography, LVRR was deifned by 2 criteria at the same time①the absolute elevation of LVEF≥10%than base line and the follow-up LVEF≥50%,②the relative reduction of left ventricular end-diastolic diameter (LVEDD) index≥10%than base line and the follow-up LVEDD index≤27 mm/m2. LVRR prevalence with its base line predictor was investigated. Results: The overall mean follow-up time was (23 ± 15) months, and 39/118 (33.1%) patients acquired LVRR as LVEF from the base line level (30.6 ± 6.8)%increased to the follow-up level (57.0 ± 4.9)%;LVEDD index from the base line level (31.6 ± 3.9) mm/m2 decreased to the follow-up level (24.4 ± 1.9) mm/m2, all P6 months vs≤6 months (OR=0.244, P Conclusion:With tailored medication, about 1/3 of patients with hypertension combining LVSD could acquire LVRR, the patients with shorter duration of HF, shorter QRS interval and higher ratio of SBP/LVEDD index had more possibilities.
