Abstract

Comparative determinants of 4-year cardiovascu-lar event rates in stable outpatients at risk of or with atherothrombosis. A proportional hazard model for the subdistribution of a competing risk. Analyzing survival data with competing risks using SAS w software. Propensity score techniques and the assessment of measured covariate balance to test causal associations in psychological research. Atherosclerotic risk factors are less intensively treated in patients with peripheral arterial disease than in patients with coronary artery disease. AT. Fate of individuals with ischemic amputations in the REACH Registry: three-year cardiovascular and limb-related outcomes. use and leg functioning in patients with and without lower-extremity peripheral arterial disease. use and functional decline in patients with and without peripheral arterial disease.

The concordance of self-report with other measures of medication adherence: a summary of the literature. A 47-year-old woman with a history of hyperten-sion and cerebral infarction presented with intermittent claudication. No pulse was palpable in the bilateral dorsalis pedis, and peripheral arterial disease was suspected. The ankle-brachial index was 0.83 in the right leg and 0.76 in the left. Duplex sonography revealed severe stenosis in the bilateral external iliac artery (EIA) and renal artery. The EIA had the characteristic 'string of beads' appearance in angiography (Panel A), which was diagnosed as fibromuscular dysplasia (FMD). Endovascular therapy was performed for the EIA. There was a 30 mmHg pressure gradient in the FMD lesion. Optical coherence tomography (OCT) images revealed shrinkage of the media and mild thickness in the intima (Panels B and C), while three-dimensional OCT images showed a 'haustra coli'-like appearance (Panel D). After balloon angioplasty, the vessel was well dilated and claudication disappeared.
