Abstract


Background to investigate how changes in body weight (BW) af fect office and ambulatory blood pressure (BP) and are related to baseline catecholamines in hypertensives with positive (FH+) and negative (FH-) family history of hypertension.
Methods in 744 borderline to mild hypertensives (535 men and 209 women) participating in the HARVEST study 24-h urine catecholamines, office and ambulatory BP (A&D TM2420 or Spacelabs 90207) were measured. Overweight patients were advised to decrease calorie intake. After 3 months ambulatory BP was repeated. Subjects were divided into two groups, according to whether their BW decreased (G1) or not (GZ) and by FH status (G1FH+, n=118; G1FH-, n=203; C=2FH+, n=178; G2FH-, n=245).
Results After 3 months BW decreased by 2,7±0.1 kg in Gl and increased by 1.0±0.1 kg in G2. Within the two groups, FH+ and FH- subjects changed BW to a similar extent. Office BP fell to a similar extent in the two groups, while ambulatory BP showed a decrease only in Gl in comparison with G2 (systolic BP (SBP)=-1.8±0.5 vs +0.3±0.4 mmHg, p=0.003; diastolic BP (DBP)=-1.7±0.4 vs 0.00.3 mmHg, p=0.001). G1FH+ subjects showed a greater response of 24-h BP fo BW loss than G1FH- (DBP=-2.5±0.5 vs O.6±0.6 mmHg, p=0.04; SBP=2.5±0.7 vs -0.8±0.8 mmHg, ns). In comparison with G2, only G1FH+ subjects showed a significant decrease in ambulatory SBP (p=0.03) and DBP (p=0.01). A negative correlation was observed between baseline urinary Dopamine and changes in 24-h BP in FH+ subjects (SBP r=-0.135, p=0.02; DBP r=-0.119, p=0.047) but not in FH- subjects. In either group no correlation was found between BP changes and Epinephrine or Norepinephrine.
Conclusions in mild hypertensives weight reduction is effective mostiy in patients with FH+. Detection of low Dopamine values is an additional reason for recommending BW loss in these subjects.
