title: A screening programme for hypertension in general practice.
abstract: It is recommended that hypertensive patients with a diastolic blood pressure of 100 mmHg be treated. However, it has been proposed that only 50% of hypertensives are diagnosed, and of these, 50% are not treated. We therefore set out to identify hypertensive patients in our practice, who were then actively treated, some in a clinical trial of ketanserin. Of the 3,384 patients (1,667 males and 2,707 females) who were invited to our surgery for a blood pressure measurement, 2,606 patients (77%) attended. The overall prevalence of hypertension in the patients, aged 35-65 years was 2.9%. This prevalence increased with age: from 1.0% in the 35-44 year age group to 3.5% at 45-54 years, and 4.4% at 55-64 years. The mean systolic but not diastolic blood pressure increased with age. There were more male hypertensives than females, except over 55 years of age. Of the 84 hypertensives identified after one visit, the majority remained hypertensive after an additional visit, and 31 agreed to participate in a clinical trial. After a four-week placebo run-in, 22 patients had a diastolic blood pressure above 95 mmHg and were randomly allocated to receive ketanserin 40 mg twice daily or metoprolol 100 mg twice daily. Treatment continued double-blind for three months. There were no significant differences in blood pressure reduction between the treatment groups. The heart rate was reduced more by metoprolol. There were no withdrawals for side effects and no major differences in subjective complaints between the two treatment groups.
