The treatment of arterial hypertension in elderly men in Iceland.

The choice of antihypertensive therapy in elderly Icelanders is unknown. In the database of the Icelandic Heart Association 1145 men, aged 70-84 were alive in 1994. Eight hundred thirty-four came to the Heart Association Clinic, 429 of whom either had hypertension or were found to be hypertensive on examination. The prevalence of hypertension in elderly Icelandic men was therefore about 50%. One hundred fifty-seven men took drugs for hypertension. Ninety-five of them were treated with a single drug, 49 with two drugs and five with three drugs. The type of drugs was unknown concerning eight men. Diuretics and ß-blockers were dominant. Although the comparison between those two classes of drugs was uncontrolled the blood pressure was significantly lower in systole on diuretics. The most common combination was ß-blockers and diuretics, then angiotensin converting enzyme inhibitors and diuretics, finally ß-blockers and calcium blockers. It is suggested that the use of diuretics should be increased in this age group.
