A simple test at the doctor's office could better predict a patient's risk for heart disease. Measuring blood pressure in the ankle and comparing it to measurements in the arm is a test often used for peripheral artery disease.
Researchers in Scotland reviewed 16 studies that looked at the effectiveness of this test and they found that patients with a low score had double the risk for cardiovascular death compared to patients with a high score. In some cases, test results moved patients into a "high risk" group.
Researchers say the test is an easy addition to a doctor's arsenal for determining heart disease risk.
