BACKGROUND: Therapeutical response to antihypertensive treatment is poorly predicted by individual clinical or biochemical characteristics. Some preliminary data indicate that therapeutical response to atenolol might depend on physical and/or sympathetic activity. The aim of the present study was to evaluate the blood pressure response to atenolol depending on physical and sympathetic activity.
PATIENTS AND METHODS: One thousand one hundred forty hypertensive patients were treated with the beta adrenorecepetor blocker atenolol in an open fashion during 3 months. Before the beginning of the treatment, we evaluated current weekly physical activity (direct interview), as well as sympathetic activity (direct interview and baseline heart rate).
RESULTS: Age or physical activity did not correlate with blood pressure response to atenolol. Conversely, hypertensive patients with symptoms suggesting sympathetic overactivity (three or more of the following symptoms: palpitations, anxiety, diaphoresis, headache, tremor or weakness; n = 456), showed a more pronounced decrease in systolic (27.7 [13.4] vs 25.8 [14.3] mmHg; p = 0.0226) and diastolic (17.6 [8.3] vs 15.5 [8.6] mmHg; p = 0.0001) blood pressures (SBP and DBP), with respect to the remaining hypertensive patients (n = 719). Moreover, we found a statistically significant correlation between blood pressure fall with atenolol and baseline heart rate (r = 0.107, P < 0.001 for SBP, and r = 0.142, p < 0.001 for DBP).
CONCLUSION: Baseline tachycardia or symptoms suggesting anxiety, emotional tension or sympathetic overactivity are associated with a more pronounced blood pressure fall to antihypertensive treatment with atenolol. These circumstances may play a role when choosing a new antihypertensive therapy.
