Peripheral artery disease (PAD) of the lower extremities is frequently due to atherosclerotic lesions of the femoropopliteal artery, which may result in disabling claudication and rest pain with or without tissue loss. More than 50% of the...

An isolated PMI is associated with significant morbidity and mortality. And because physicians often fail to recognize this diagnosis, there may be delays in the timely revascularization of these patients. The present study sought to identify...
