Weight Gain
| | Abstract | BACKGROUND: Overweight and obesity are associated with cardiovascular disease (CVD). This study was designed to investigate whether combined use of nitrendipine and atenolol has any effect on body weight (BW) and whether metformin can prevent antihypertensive medication-induced weight gain and has any effect on blood glucose (BG).
METHODS: Included in the present study were 94 hypertensive patients with a body mass index (BMI) > or =25 kg/m(2), of whom 45 patients were treated with nitrendipine plus atenolol (N/A group), and the remaining 49 patients were treated with nitrendipine, atenolol, and metformin (N/A/M group). The mean follow-up duration was 14 months. BW and glucose tolerance were measured.
RESULTS: In N/A group, BW and fasting BG significantly increased from 73.5 +/- 9.6 kg to 74.2 +/- 9.7 kg (P < 0.05) and from 94.2 +/- 10.5 mg/dl to 97.9 +/- 11.3 mg/dl (P < 0.01), respectively, whereas postprandial BG did not change significantly. In N/A/M group, BW slightly decreased from 72.7 +/- 10.1 kg to 72.3 +/- 10.2 kg (P = 0.30), and fasting BG did not change significantly (93.5 +/- 10.4 mg/dl vs. 92.7 +/- 10.2 mg/dl, P = 0.59), whereas 2-h postprandial BG significantly decreased from 133.7 +/- 30.5 mg/dl to 124.0 +/- 29.6 mg/dl (P < 0.05). Furthermore, a significant difference was observed in difference value of BW before and after treatment between the two groups (0.7 (95% confidence interval, 0.1-1.3) kg in N/A group vs. -0.4 (95% confidence interval, -1.3 to 0.4) kg in N/A/M group, P < 0.05).
CONCLUSIONS: Combination therapy of nitrendipine and atenolol may significantly increase BW and fasting BG in overweight or obese patients with hypertension. Metformin may prevent BW gain and improve BG levels in hypertensive patients who received combination therapy of nitrendipine and atenolol. | | Language | eng | | Pub Type(s) | Journal Article
