PURPOSE:This study was aimed at evaluating the prevalence of peripheral arterial disease of the lower extremities and its prognostic value in a population of patients from the Haute-Garonne department, who were hospitalized for acute coronary artery disease.METHODS:Between 1985 and 1991, four thousands three hundred and sixty-eight patients (3,680 males and 688 females) presenting with acute coronary artery disease were included in the study.RESULTS:The prevalence of peripheral arterial disease of the lower extremities was 13.4%, increasing with age and being higher in male patients. In regard to patients hospitalized for acute myocardial infarction (n = 2,417), independent relationships were observed between the 28-day mortality and the following: patient's age (odds ratio: 1.02; 95% confidence interval: 1.01-1.04; P < 0.0005), female gender (odds ratio: 1.32; 95% confidence interval: 1.17-1.54; P < 0.002), inclusion in the study (odds ratio 0.95; 95% confidence interval: 0.90-0.99; P < 0.02), previous coronary artery disease (odds ratio: 2.88; 95% confidence interval: 2.32-3.48; P < 0.0001), and peripheral arterial disease (odds ratio: 1.61; 95% confidence interval: 1.26-2.06; P < 0.0001).CONCLUSION:The prevalence of peripheral arterial disease of the lower extremities is high in patients with acute coronary artery disease in both genders, whatever the age. This disease is therefore an independent marker of mortality for acute myocardial infarction. Easy diagnosis of peripheral arterial disease of the lower limbs by measurement of the ankle pressure index allows identification of patients prone to death from acute myocardial infarction.

The authors report the case of a woman admitted to hospital for minor trauma of the left hip and who presented major ST segment elevation on the second day suggesting an acute anterior wall myocardial infarction at the same time as a cerebrovascular accident. Complementary investigations and follow-up excluded the diagnosis of myocardial infarction with normalisation of the ECG on the 5th day. ECG changes during cerebrovascular accidents may be very variable ranging from extrasystoles to ST elevation mimicking myocardial infarction. They carry a poor prognosis with an increased risk of sudden death necessitating continuous ECG monitoring until the ECG reverts to normal. The cardiac involvement is not ischaemic but due to disease of the insular cortex of the brain which induces myocytolysis (centered around the intra-cardiac nerve endings) due to the sudden liberation of catecholamines. These lesions may be treated by propranolol or phentolamine.
