Abstract
Intermittent claudication has been claimed to be a side‐effect of β‐adrenoceptor blocking drugs. The confounding effect of coronary heart disease has not been controlled in earlier studies. In this case‐control study, the cases were selected from a hospital material of patients with verified intermittent claudication and the controls from a nationwide health survey. The pool of potential cases and controls consisted of persons who had been treated with antihypertensives, but did not have coronary heart disease. The controls and cases were matched for age, sex, place of residence and time of examination. Comparison of current or previous use of β‐blocking drugs among our 55 case‐control pairs revealed no association between intermittent claudication and β‐blockade. β‐Blockade is not a risk factor for intermittent claudication.
