Blood pressure and arm circumference during large weight reduction in normotensive and borderline hypertensive obese patients.
Blood pressure (BP) and arm circumference were measured in 44 normotensive and borderline hypertensive obese patients during treatment with either a very low calorie diet or diet supported with gastroplasty. The patients had reductions in sodium, energy, and carbohydrate intake. BP was determined with both a normal cuff (12-by-35 cm bladder) and a large cuff (15-by-43 cm bladder), using a random-zero sphygmomanometer. Both systolic and diastolic BP declined (p less than 0.005) (from 133 to 124 +/- 4 mmHg and from 87 to 81 +/- 3 mmHg (mean +/- SED), respectively), but reached a plateau after an average weight loss of 11 kg. No further reduction in BP was seen despite a maximal weight loss of 40 kg. At the same time arm circumference decreased from 36.4 to 30.5 cm. Moreover, the study showed that reductions in systolic and diastolic BP were closely associated with the pretreatment BP but not with the weight loss. The normal cuff overestimated the systolic BP by 8 +/- 4 mmHg and the diastolic BP by 6 +/- 3 mmHg (mean +/- SED) in patients with arm circumference of 35 cm and more.
