Control of blood pressure morning surge in a Lebanese hypertensive population

OBJECTIVE: The primary endpoint of this prospective clinical study is to ascertain the degree of blood pressure control in the early-morning hours after 8 weeks of treatment with Telmisartan in hypertensive patients using home blood pressure measurements. METHODS: Two hundred forty Lebanese patients with uncontrolled hypertension are enrolled in the study. The blood pressure is measured at the initial visit, then at week 4 of follow-up (optional visit) and after the 8 weeks period, by the physician at his office (with pulse rate) and by the patient at home in the morning. RESULTS: The blood pressure measured by the patient at home in the morning has a mean value of 129.7/79.1 mmHg, significantly less than 135/85 mmHg (P < 10(-1)), and it is reduced by 31.9/13.5 mmHg (P < 10(-5)). At the physician's office, the reduction is 34.8/16 mmHg (P < 10(-4)). Heart rate is decreased by 4.7+/-0.5 bpm (P < 10(-5)). The drug was well tolerated. CONCLUSION: This study has demonstrated that Telmisartan, by his long half-life, protects the patients against the early-morning hours blood pressure surge, period during which coronary and cerebral events are the most frequent.
