Blood tests that detects NT-pro-BNP in blood can forecasts heart attack or stroke
Voice of America: The World Health Organization (WHO) says that cardiovascular disease causes approximately one third of all deaths worldwide (16.7 million). And those deaths are not just limited to industrialized nations. By 2010, the WHO estimates that heart disease and stroke also will be the leading causes of death in developing countries. But the WHO says heart disease is not always a death sentence. At least 20 million people survive heart disease and stroke every year. And now a blood test can accurately predict a patient's chances of a heart attack.
Many people already know what they should do to avoid a heart attack or stroke: Stay away from foods full of saturated fat, salt and carbohydrates. Eat more fruit and vegetables. Exercise more. Don't smoke. Take a cholesterol-lowering drug.
But sometimes the odds of a future heart attack or stroke are still higher for those people who have already been diagnosed with cardiovascular disease.
Sixty-four-year-old Thomas Gray has survived two heart attacks and is under regular medical care. But his doctor, Kirsten Bibbins-Domingo, believes the more she knows about the risk, the more aggressive his treatment can be. "The things we were interested in are things like a heart attack, a stroke, heart failure or dying from your heart disease."
Dr. Bibbins-Domingo and a team of medical researchers in San Francisco, California followed the progress of at least 900 heart patients. Their findings, published in the Journal of the American Medical Association, showed that the presence of a marker called NT-pro-BNP in the blood helps forecast a possible attack.
