Low ankle-brachial pressure index in 68-year-old men: prevalence, risk factors and prognosis. Results from prospective population study " Men born in 1914", Malmö, Sweden.
The objectives were to study the distribution of ankle-brachial pressure indices (ABPI) in elderly men in relation to arteriosclerotic risk factors, cardiovascular morbidity and total mortality. The data are taken from the prospective cohort study " Men born in 1914" in Malmö, a city in southern Sweden with 220,000 inhabitants and a single referral hospital. Prevalence of low ABPI (< 0.90) at 68 years of age, total mortality, mortality from ischaemic heart disease (IHD) International Classification of Diseases (ICD) code 410.0-412.9) and cardiac event rate [fatal and non-fatal myocardial infarction (MI) and mortality from chronic ischaemic heart disease] during 8 years of follow-up was measured. Sixty-seven of 477 randomly selected men (14.0%) had an ABPI < 0.90 in one or both legs, 18/477 (3.8%) had intermittent claudication according to the Rose questionnaire, which had a sensitivity of 14.9% and a specificity of 98% when using ABPI as a reference method. Ninety-two per cent of the men with an ABPI < 0.90 were or had been smokers, compared with 80% of the men with an ABPI > or = 0.90. Mean systolic blood pressure and median plasma triglyceride levels were significantly higher in the group with low ABPI. Thirty (45%) of the men with low ABPI and 87 (21%) of the men with pressure indices above 0.90 died during follow-up (p < 0.001). Cardiac event rate was 25% (17/67) in the group with low ABPI and 10% (41/410) in the other group (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)[1]References
