Finger test can catch early signs of Heart Disease

Heart diseases have become a very common even in young people. Risk of developing heart disease is no longer just a hereditary factor; hectic and sedentary lifestyles also contribute to its development. Screening of people for heart diseases could help in prevention of heart disease.

Researchers have found that a simple fingertip probe could reveal heart disease risk without even drawing a drop of blood. This noninvasive test is called reactive hyperemia peripheral arterial tonometry (RH-PAT). Some day it may become standard testing quipment in doctor’s clinics.

In this, the test gauges blood flow at the fingertip before and after a blood pressure cuff is inflated at the arm. It is an indirect measure of the health of the lining of blood vessels. According to the researchers, accessing the healthy function of blood vessels has been shown to predict cardiovascular disease.

A study was conducted on 94 people to test this new found screening process. None of the participant had heart disease, but a little more than half had an early warning sign of looming heart trouble.

After the blood pressure cuff is deflated, the probe measures how well blood flow changes in the finger as blood pulses through it. The average RH-PAT index was higher in people with vascular disease. If the finger’s blood vessels are abnormal, those around the heart could be troubled, too.

However, the researchers say that the RH-PAT test requires wider testing.
