[Comparative analysis of the combined treatment efficacy of the Chernobyl accident clean-up workers with essential hypertension].

It was shown the results of comparative evaluation of combined treatment in 111 clean-up workers of Chernobyl accident with essential hypertension (EH). This treatment consist of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers in combination with calcium channel blockers and diuretics. The follow-up period lasted 12 months. It was found that combined therapy provides comparable and reliable blood pressure (BP) control during 24-hour, significant reduction of average daily BP, daytime and nighttime BP, an index of time of the BP, BP variability. Despite on achieved target blood pressure level, 4 weeks treatment is not enough for regression of left ventricular hypertrophy (LVH). Significant regress of LVH was found if treatment lasted during a year under the condition that BP remained at the target level. It was revealed the advantage of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers intake combined with a diuretic on regress of left ventricular hypertrophy and dysfunction.
