BACKGROUND: Achievement of a controlled blood pressure and improvement of cardiovascular risk profile are the mainstays of therapy for hypertension.
OBJECTIVE: To assess the responses of heart rate and blood pressure in hypertensive patients to 240 mg/day sustained release verapamil.
METHODS: We assessed the effect of 240 mg/day sustained released verapamil on blood pressure and heart rate, measured in the office and at home, in 1395 hypertensive outpatients with mild-to-moderate hypertension, who were using an Omron HEM 705 CP automatic device for self-measurement. The period of observation was 3 months.
RESULTS: Blood pressure decreased both in the medical office and at the patient's home, the measurements obtained at home being lower than those found in the office. Heart rate decreased in a significant and particular way. The decrease was greatest among those patients with histories of myocardial infarction and among relatively young patients, who exhibit a tendency towards higher than normal baseline heart rates. Overall, there was a shift of the heart-rate curve towards more controlled levels clustered around heart rates between 65 and 75 beats/min. Home self-measurement showed that the data gathered by the patients at home are reliable and that, when cut-off values of 140/90 mm Hg for blood pressure are used, the percentage of patients with controlled blood pressures is 62%, whereas the percentage obtained in the medical office by the physician is 56%. If cut-off values of 135/85 mm Hg are considered for self-measurements at home, according to the VI JNC recommendations, the percentage of patients with controlled blood pressures is 25.4%.
