Time is one of the prime factor that plays significant role in coronary artery disease (coronary arteries are found on the walls of heart surrounding it). An appropriate timely intervention can allow the treatment process start much earlier to avoid a potential heart attack. However, this don’t happen in real life much because we probably have no such test to identify the disease in advance. Doctors too have a hard time narrowing their differentials of probable causes of someones chest pain to pinpoint it towards a coronary artery disease. As a part of their work they need to do a bunch of expensive tests.
Now the question is how this coronary arteries narrow and finally leads to a heart attack. A process called atherosclerosis stiffens and gradually decrease the diameter of these arteries. Such changes in the artery occur due to various fact and not limited to age, sex, smoking and fatty diet only.
Interestingly, researchers found that small DNA fragments are actually found in blood of people in whom such coronary artery narrowing occurs. If this particles can be detected by laboratory tests it can diagnose the coronary artery disease much earlier and help promote introducing preventive steps to slow its progression. Furthermore, this will also allow an rapid diagnosis of chest pain, instead of waiting for test results of conventional set of tests. In addition to this it also may decrease need of certain expensive cardiac tests and may some day allow its use as a common test in a general practitioners office. If this new DNA fragments identifying methods are introduced in future this may change our cardiac preventive health care approach vastly. Earlier we pick the disease, better we prevent its progression.
