Evaluation of Effects of Exercise Training and ARB in DM Patients

Inclusion criteria

type II diabetic and hypertensive patients who are aged 30 to 70 year-old with HbA1c ≤ 8.0 % and systolic blood pressure ≥ 140 mmHg. Neither ACEI nor ARB is administrated in recent 6 months. None has significant concomitant systemic diseases such as active infection, malignancy, hepatic or significant renal dysfunction at the time of enrollment (i.e. total bilirubin > 3 mg/dl，ALT > 2.5 times the upper limit of normal range and creatinine > 3 mg/dl in our hospital). Information regarding smoking, hypertension, hyperlipidemia as well as history of cardiovascular disease is obtained from all subjects. No other medication will be modified during the study period. After enrollment, patients are assessed to (1) olmesartan (20 mg per day, with titration), (2) life modification/exercise training for 12 weeks. Vascular function and exercise capacity studies, and peripheral blood testing are performed at baseline and at 12- week follow-up. Data are collected as mean ± SD showing comparison between groups by use of 2-sample t test and chi-square analysis for continuous and categorical variables, respectively. Adjust for the HbA1c level will be adjusted using simple adjustment method (ANCOVA or equivalent regression analysis) while doing the data analysis. Changes between baseline and follow-up measurements are assessed by paired t test. The frequencies of adverse effects between groups will also be comparing by 2-sample t test. A p value <0.05 is defined as statistically significant.
