ABSTRACT
OBJECTIVE@#To determine the effect of trimetazidine on cardiac function and exercise tolerance in primary hypertension patients with type 2 diabetic.@*METHODS@#In this randomized, double-blind, placebo-controlled prospective study, 60 primary hypertensive patients with diabetic were equally assigned into two groups, patients received trimetazidine (20 mg, 3 times a day) or placebo for 1 year. Echocardiography, cardiopulmonary exercise testing were performed; and the plasma N terminal pro B type natriuretic peptide (NT-ProBNP), hr-CRP, TNF-α, angiotensin Ⅱ and endothelin concentration were determined before and after treatment.@*RESULTS@#In trimetazidine group, the left ventricular mass index, the mitral flow velocity E wave to A wave ratio (E/A), the peak early diastolic velocity (V) to late diastolic velocity (V) ratio (V/V) and the peak systolic velocity (Vs) were significantly improved, the plasma NT-ProBNP level was significantly decreased, and the exercise time, metabolic equivalent, maximal oxygen uptake and anaerobic threshold were significantly increased (all 0.05). No severe adverse reaction was observed in both groups.@*CONCLUSIONS@#For patients with both hypertension and diabetes, trimetazidine can improve cardiac function and increase exercise tolerance.
