Diagnosing PAD Before Symptoms

September 2, 2009
According to researchers at University of North Carolina at Chapel Hill a simple test that measures blood flow through the ankle helps identify people with peripheral artery disease (PAD) before they start showing symptoms. The test, called an ankle brachial index (ABI), may be useful in screening people who have already suffered a stroke or transient ischemic attack (TIA). Said the principal investigator Dr. Souvik Sen, "Stroke and TIA survivors are already at risk of suffering another stroke, TIA, heart attack or death. Our study found that 26 percent of survivors also had PAD without showing any symptoms, and this group suffered three times more subsequent strokes, heart attacks and deaths than survivors without PAD.”
