*p<0.05 compared with the value at baseline, by the Wilcoxon’s test. ^∆p<0.05 compared with the value in control group, by the Mann-Whitney U test. DBP, diastolic blood pressure; HR, heart rate; LVDD, left ventricular diastolic diameter; LVEF, left ventricular ejection fraction; LVSD, left ventricular systolic diameter; SBP, systolic blood pressure
