The ECG diagnosis (the current procedure) can easily diagnose the major heart attacks (Acute Myocardial Infarction. AMI). But the smaller or minor heart attacks are common and diagnosing them is challenging.
The current test procedure involves checking for the biomarkers such as cardiac troponins to detect the heart damage (or a risk of heart attack ). This test will classify an individual as the low risk of heart attack if the cardiac troponins are untraceable and the patient will be discharged from the hospital immediately. But up to 85 percent of the patients of chest pain are being classified as the intermediate risk group, which requires an overnight stay at the hospital for further observation and blood tests, causing an increased medical cost.
Now, the damage to the heart can be detected quickly within 20 minutes with a new procedure developed by the scientists at King's College London, United Kingdom (UK). The new test procedure will check the cardiac myosin-binding protein C (cMyC) in the blood.
The researchers have found that this biomarker in the blood is more sensitive after the damage to the heart muscle as its level increases rapidly compared to the cardiac troponins. A quick diagnosis of the damage to the heart muscle can be done with this new test.
The current test procedure is failing in the detection of the damage to the heart muscle. But the new test enables an accurate detection of the heart attack. The patients without heart attack symptoms can be sent home.
A study funded by the British Heart Foundation (a charity organization) has conducted a trial with the new test procedure to detect the damage to the heart muscle on more than 2,000 patients of an acute chest pain in Europe.
The new test procedure has found no heart attack incidence in a double the number of patients compared to the current procedure. Researchers say that the new test procedure will be implemented on the NHS within five years.

A Spanish study corroborates the significance of taking breakfast for the health of the heart. This study shows a double risk of atherosclerotic plaques and cardiovascular diseases among those individuals who skipped the breakfast or if the total calories of the breakfast (in calorie) is less than five percent of the recommended daily calorie consumption compared to those individuals who ate high-calorie breakfast.
Researchers in the current study has analyzed the health of 4,000 middle-aged people working in offices. Researchers monitored the events and the development of atherosclerotic plaques in them. Their routine consumption of breakfast was as follows.
Researchers used ultrasound technology to find out the atherosclerotic plaques in all the participants. When compared with participants who are under the category of high-energy breakfast, the study shows:
