    Journal: Kardiologiia; 2002; 42(2):28-33. PubMed ID: 12494204.
    Abstract:
    AIM: To compare antiischemic effects of trimetazidine in patients with stable angina pectoris with and without disturbances of carbohydrate metabolism. MATERIAL: Patients with ischemic heart disease, stable class II-III angina pectoris and reproducible positive results of on-treatment exercise tests (n=40, mean age 56.7-/+1.95 years, 37 men) with normal carbohydrate metabolism (group 1, n=20) and with disturbances of carbohydrate metabolism (group 2, n=20). METHODS: All patients in addition to individually selected antianginal therapy were given trimetazidine (60 mg/day) for 2 months. Bicycle exercise tests were repeated after 1 and 2 months. Patient's diaries were used for registration of anginal attacks and nitroglycerine consumption. RESULTS: Addition of trimetazidine was associated with significant (p<0.005) prolongation of exercise duration until 1 mm-ST depression in both groups. Exercise duration was 553-/+10.5 and 555-/+10.2 s (p>0.05) at baseline, 657-/+15.3 and 695-/+10.1 s (p<0.05) after 2 months in groups 1 and 2, respectively. Other effects of trimetazidine in groups 1 and 2 included increases of total work performed during exercise test (by 14 and 22%, respectively), decreases in numbers of patients with ST depression (by 40, p<0.05, and 50%, p<0.05, respectively), numbers of anginal attacks (by 30, p<0.001, and 43%, p<0.001, respectively) and nitroglycerine pills (by 13%, p<0.001 and 51%, p<0.001, respectively). The decrease in supplemental nitroglycerine consumption was significantly more pronounced in group 2 (p<0.0001). There was no significant increment in double product in both groups. CONCLUSION: Antiischemic effect of trimetazidine was greater in patients with angina pectoris and disturbances of carbohydrate metabolism than in similar patients without such disturbances.
