[Combined antihypertensive treatment of patients with hypertension and type 2 diabetes mellitus].

AIM

To investigate antihypertensive efficacy, effects on endothelial, diastolic function of the left ventricle and metabolism of combination of ACE inhibitor quinapril (accupro) with diuretic indapamide SR in patients with hypertension of the second-third degree and type 2 diabetes mellitus (DM) and free of DM.

MATERIAL AND METHODS

Outpatient treatment was given to 60 patients with AH (mean age 55.3 +/- 9.6 years) in combination with mild or moderate DM (group 1) and free of DM (group 2). The patients were observed for 12 weeks. Clinical and biochemical blood tests, ECG, echo-CG, measurements of blood pressure were made in all the patients.

RESULTS

Quinapril course (mean dose 23.3 +/- 9.8 mg/day) in combination with indapamide (1.5 mg/ day) produced a complete hypotensive effect in group 1 (23 patients, 76.7%), in group 2--25 (83.3%). DM patients demonstrated reduction of fasting and postprandial glycemia and cholesterol, time of isovolumic relaxation reduced in group 1 by 9.1%, in group 2 by 19.8% (p < 0.01). Left ventricular diastolic function improved, endothelium-dependent vasodilation in diabetics rose by 40%, non-endothelium-dependent--by 21.8%, in hypertensive patients free of DM--by 51.9 and 43.2%, respectively.

CONCLUSION

Combination of quinapril with indapamide produces a significant antihypertensive effect in patients with AH of degree II-III associated with type 2 DM, improves carbohydrate and lipid metabolism, left ventricular diastolic function.
