AIM There are few studies to be found in the literature on ankle-brachial index in sickle cell disease. The aim of this study was to compare ankle-brachial index of steadystate adult sickle cell anaemia patients with that of normal controls. METHODS A descriptive cross-sectional study of 62 sickle cell anaemia patients and 62 age- and gender-matched normal controls was carried out in the adul...

Screening for lower extremity peripheral arterial disease (PAD) is essential in assessing a patient’s risk of cerebrovascular disorders. The ankle-brachial index (ABI) widely used as screening tool PAD, but it can produce falsely normalized results due to factors like artery calcification and collateral vessels. We report patient with normal ABI confirmed PAD through ultrasound computed tomogra...

Patients with peripheral arterial disease including those with intermittent claudication have a high risk for cardiovascular and cerebrovascular morbidity and mortality. The outcome of patients with intermittent claudication is less limited by local complications in the leg than by the systemic complications of coronary and cerebral vessels. About 30 % of these patients will die within 5 years,...

Dear Editor, We have read the article ‘‘Ankle-brachial index as a predictor of coronary disease events in elderly patients submitted to coronary angiography’’ by Eduardo D. E. Papa et al. (1). These authors aimed to evaluate the value of the ankle-brachial index (ABI) as a marker of cardiovascular events in elderly patients and to evaluate the relationship between the ABI and the extent of coro...

The purpose of this study is to measure blood velocities in carotid, brachial and femoral arteries with synchronized measurement of electrocardiogram (ECG) during head-up tilt (HUT) using a developed telemetry measurement system. The velocity waveforms and ECG are continuously measured in six putatively healthy young subjects for 130 s during supine and 90 degrees HUT. From the measured peak sy...
