To analyse patient's isolated systolic hypertension (ISH) in relation to the body mass index (BMI). 11,436 patients with SBP > or = 140 and DBP < 90 mmHg were examined by 1,464 GPs who filled in a questionnaire for each patient: the patient's BP, risk factors, the presence of target organ damage (TOD) and antihypertensive treatment. 11,100 patients were split into 3 groups depending on their BMI: Gp 1 (BMI < 25 kg/m2: 4,324), 39%; 62 +/- 14 yrs; 44% men; BP: 157/80 mmHg, 55% treated; Gp 2 (BMI 25 and 30 kg/m2: 5,164) 47%; 62 +/- 12 yrs; 61% men; BP: 158/81 mmHg, 63% treated; and Gp 3 (BMI > 30 kg/m2: 1,612) 14%; 62 +/- 12 yrs; 49% men; BP: 159/81 mmHg, 75% treated. 11,085 patients' CV risks were analysed and categorised into high (HR), medium (MR) and low risk (LR). [table: see text] 11,100 patients' CV history (CVH) were analysed: > 1 CVH were 1,056 (24%) into Gp 1; 1,531 (30%) into Gp 2 and 653 (41%) into Gp 3; left ventricular hypertrophy was 454 (10%) into Gp1; 815 (16%) into Gp 2 and 388 (24%) into Gp 3. 61% patients with ISH carry excess weight and 14% are obese. In spite of a more frequent antihypertensive treatment which gives comparable BP levels, the higher the BMI, the higher the CV risk and CV history. Treatment of all CV risks is therefore necessary.
