Abstract´╝Ü Objective To investigate the effects of physical exercises on cardiac function and plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in hypertensive patients combined with diastolic cardiac dysfunction.Methods A total of 66 essential hypertension patients who had abnormal left ventricular relaxation and normal systolic function were assigned to the intervention group ( n =33 ; doing physical exercises once a day,5 days a week) or control group (n =33 ).All the patients received standard treatment.At 6 months,body weight,blood pressure,heart rate,NT-proBNP,and echocardiography were measured.Results At 6 months,body weight [ (68 ± 7 ) kg vs (72 ± 8 ) kg ],systolic blood pressure [ (135.4 ±5.1) mm Hg (1 mm Hg =0.133 kPa) vs (141.9 ±5.2) mm Hg ],diastolic blood pressure [ (81.1 ±4.0) mm Hg vs (84.7 ±4.6) mm Hg],New York Heart Association class (1.4 ±0.3 vs 1.8 ±0.4),NT-proBNP level [ (526 ± 126 ) ng/L vs (741 ± 189 ) ng/L] were significantly decreased in the intervention group when compared with the control group ( all P < 0.05 ) although left ventricular ejection fraction (LVEF) (62.9 ±6.7 vs 59.0 ±5.6) and E/A ratio ( 1.1 ±0.3 vs 0.9 ±0.3) were significantly increased ( both P < 0.05).Conclusion Physical exercises could play a role in reduced blood pressure and body weight and improved cardiac function in hypertensive patients with diastolic cardiac dysfunction.
