BACKGROUND The renal resistive index (RI) is calculated as (peak systolic velocity - minimum diastolic velocity)/peak systolic velocity, and has been significantly associated with renal function. Pulse pressure index (PPI) is derived from a formula similar to renal RI, i.e. (systolic blood pressure - diastolic blood pressure)/systolic blood pressure. The purpose of this study was to investigate...
BACKGROUND Approximately 20% of patients undergoing ankle brachial index testing for critical limb ischemia have noncompressible vessels because of tibial artery calcification. This represents a clinical challenge in determining tibial artery patency. We sought to identify the prevalence of tibial artery and pedal arch patency by angiography in these patients. METHODS AND RESULTS One hundred ...
OBJECTIVES Previous studies have demonstrated that both low and high hemoglobin concentrations are predictive of adverse cardiovascular outcomes in various populations. However, an association of hemoglobin with the ankle-brachial index, which is widely used as a screening test for peripheral arterial disease, has not yet been identified. METHODS We examined 786 subjects (236 women and 550 me...
Background Peripheral arterial disease is an atherosclerotic disease characterized by an increase in morbidity and mortality. For these reasons early diagnosis of peripheral arterial disease is important. Ankle-brachial systolic pressure index measurement is frequently used in screening studies. Evaluating waveforms of distal lower extremities with Doppler ultrasound can be used as a screening ...
background: this study was conducted to assess the validity and reliability of ankle?brachial index (abi) by oscillometric blood pressure (bp) measurement as compared with an automated abi as a gold standard. materials and methods: this study was conducted at golden jubilee medical center, thailand. all the data were collected from 303 patients at risk of peripheral arterial disease (pad) who w...
BACKGROUND In the last years significant attention has been paid in identifying markers of subclinical atherosclerosis or of increased cardiovascular risk. METHOD An abnormal ankle/brachial index (ABI) identifies patients affected by lower extremity peripheral arterial disease, and even more important, represents a powerful predictor of the development of future ischemic cardiovascular events...
OBJECTIVES This cross-sectional study aimed to individually and cumulatively compare sensitivity and specificity of the (1) ankle brachial index and (2) pulse volume waveform analysis recorded by the same automated device, with the presence or absence of peripheral arterial disease being verified by ultrasound duplex scan. METHODS Patients (n=205) referred for lower limb arterial assessment u...
OBJECTIVES We examined the ability of ankle brachial index, C-reactive protein and central augmentation index to identify individuals in the general population with severe atherosclerosis, diagnosed as those with ischaemic cardiovascular disease. METHODS AND RESULTS We examined 4159 randomly sampled individuals from the Danish general population, of which 250 had severe atherosclerosis. After...
