The belief that non fasting blood sugar helps to predict Cardiac ailments and strokes may be unfounded.
It was thought that a non fasting blood sugar test is a sure shot method to predict heart and stroke risks. However this belief was busted in a recent study.
The non fasting blood test which indicates blood sugar control by taking an average value over a period of three months was believed to be an indicator of the risk of cardiac ailments in the future. Doctors hoped that adding this test also known as glycated hemoglobin or HbA1c along with other risk factors like smoking, increasing age and cholesterol levels will give them an ability to forecast any future incidence of cardiac ailment or stroke.
A recent analysis of data obtained from 73 studies conducted on 295,000 subjects without any history of Diabetes or Cardio Vascular Disease has put into question the very rationale of going for any non-fasting blood sugar test. The study revealed that Measuring HbA1c wasn’t associated with “clinically meaningful improvement” in assessing heart and stroke risks.
Measuring fasting glucose, HbA1C or both for predicting Cardiac ailments or Stroke risks was first suggested by the Canadian Cardiovascular Society in 2012.Doctors have been using the risk prediction categories to segregate patients for more evaluative tests like stress test or to prescribe drugs.
According to Dr. Emanuele Di Angelantonio of the University of Cambridge in the U.K and his co workers dealt with the issue in length, in the Wednesday’s issue of the Journal of the American Medical Association, adding HbA1c to conventional CVD risk factors did not lead to any tangible improvement in predictions of these diseases.
The participants of the evaluation were mostly from North America or Europe and the average age of the participants when the study began was 58 years. Past the Nine year half way point of the study, there were 20,840 fatal and nonfatal cardiovascular events such as heart attacks and strokes. Including other procedures like testing fasting blood sugar did not help the predictions.
