A new blood test can help doctors more quickly determine whether patients arriving in the emergency room with chest pain are having a heart attack, a US study has confirmed.
According to new research published in the American Heart Association’s journal Circulation, initial high-sensitivity test ruled out a heart attack in 30 percent of patients. The second, done at the one-hour mark, put another 25 percent in the clear.
Overall, the study found, that by the three-hour point, the high-sensitivity test had ruled out a heart attack in 84 percent of patients — versus 80 percent with the conventional test.
“We did not miss any heart attacks using this test in this population,” said lead author Rebecca Vigen, MD, MSCS, a cardiologist at the University of Texas Southwestern Medical Center, adding, “The test also allowed us to determine faster that many patients who had symptoms of a heart attack were not having a heart attack than if we had relied on the traditional test.”
The other patients had abnormal troponin results and received further evaluation. In the end, 2 percent were diagnosed with a heart attack, while others had heart-muscle damage from other causes.
The high-sensitivity test did not miss any heart attacks, Vigen said.
The test can help speed a heart attack diagnosis. But the biggest advantage, according to Dr Christopher Granger, a cardiologist at Duke University in Durham, NC, is that it more quickly rules out a heart attack in the many patients who are not having one. Grangeralso serves on the American College of Cardiology/American Heart Association guideline committee for heart attack care.
“And that’s important to patients and their families,” he said.
One hope, Granger noted, is that the quicker test will encourage people with possible heart attack symptoms to call 911 and get help immediately. As it stands, people often dismiss symptoms because they don’t want to go the ER.

Adding glass of milk in breakfast can lower blood glucose
Several research studies have attempted to find a link between drinking milk and a reduced risk for experiencing type 2 diabetes and a new research has found that adding a glass of milk in breakfast is the perfect energy boost for body needs to get through the day.
According to a study published in the Journal of Dairy Science, consuming milk with breakfast cereal reduced postprandial blood glucose concentration compared with water, and high dairy protein concentration reduced postprandial blood glucose concentration compared with normal dairy protein concentration.
H Douglas Goff, PhD, and the team of scientists from the Human Nutraceutical Research Unit at the University of Guelph, in collaboration with the University of Toronto, examined the effects of consuming high-protein milk for breakfast on blood glucose levels.
The high-protein treatment also reduced appetite after the second meal compared with the low-protein equivalent.
“Metabolic diseases are on the rise globally, with type 2 diabetes and obesity as leading concerns in human health. Thus, there is an impetus to develop dietary strategies for the risk reduction and management of obesity and diabetes to empower consumers to improve their personal health,” Goff and his team noted.
Although the team only found a modest difference in food consumption at the lunch meal when increasing whey protein at breakfast, they did find that milk consumed with a high-carbohydrate breakfast reduced blood glucose even after lunch, and high-protein milk had a greater effect.
Milk with an increased proportion of whey protein had a modest effect on pre-lunch blood glucose, achieving a greater decrease than that provided by regular milk.
Likewise, a 2014 study from Lund University in Sweden published in the American Journal of Clinical Nutrition found eating high-fat milk and yogurt reduces a person’s type 2 diabetes risk by as much as one-fifth.
Another study published in the 2011 American Journal of Clinical Nutrition tracked the relationship between a person’s dairy consumption during adolescence and their risk for type 2 diabetes as an adult. The researchers concluded that “higher dairy product intake during adolescence is associated with a lower risk of type 2 diabetes.”Follow @gorkhapost
