Quick View
To determine if a person had a heart attack, injury to cardiac muscle and to determine the progress of angina (chest pain related to cardiac issue).
Troponin I is tested Immediately after an episode of angina. A series of troponin tests are done when a person has signs and symptoms of a heart attack (pain in chest, shoulders, neck, jaw and/or shortness of breath), when angina worsens and it does not improve with rest.
1. What is a heart attack?
Heart attack means that some of the cardiac muscle tissue is severely injured or has died. It is called myocardial infarction in medical terminology. The general term for this condition is acute coronary syndrome (ACS), as it is not always possible to determine whether it is a serious injury or an infarction.The signs and symptoms of a heart attack begin with a sensation of heavy pressure or pain in the chest, often radiating to the neck or left arm. A person may experience difficulty in breathing, weakness and cold sweats.
A heart attack occurs usually due to blockage of one of the coronary arteries (blood vessels that bring blood to your heart). The blockage is usually due to atherosclerosis which occurs gradually over many years as lipid plaques are deposited along the walls of the blood vessels. These lipid plaques can narrow and stiffen the arteries and result in unexpected rupture unexpectedly.
2. Does a chest pain, always mean a heart attack?
Chest pain can be caused due to many other problems such as heartburn, other problems involving the stomach and esophagus, emotional stress and lung problems. Rarely chest pain may be due to temporary heart spasms and is called variant angina. Variant angina ususlly occur at night when a person is at rest. It can cause severe but temporary pain. If the chest pain lasts longer, even at rest, immediate medical attention is required.
3. What is a high-sensitivity troponin (hs-troponin) test?
High-sensitivity troponin (hs-troponin) test detects the same protein that the standard troponin tests do, but at much minute quantities. As this test is more sensitive, it becomes positive sooner and may detect acute coronary syndrome and cardiac injury much earlier than the standard test. The hs-troponin test may also be positive in stable angina patients and even asymptomatic patients. When hs-troponin test is elevated in these individuals, it indicates an increased risk of future heart attacks.
