Coronary artery disease (CAD ) or Ischemic heart disease (IHD) is the most common type of heart disease. It is one of the four causes of death throughout the world, including in Thailand which has 29.9 deaths per 100,000 population.
Coronary artery disease happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other materials, called plaque, on their inner walls and cause damage and inflammation. As a result, the arteries are thicker. Patients have symptoms when the artery narrows by 50% or more. Symptoms of coronary artery disease are chest pain (angina), tremors, sweating, more tired after exercise, unconsciousness, or sudden death from lack of blood to the heart muscle for too long.
Risk factors for Coronary artery disease include high blood lipids, diabetes, high blood pressure, smoking, obesity, stress, family history, etc. We can prevent and reduce the risk of coronary heart disease by changing lifestyle, healthy diet, physical activity, reduce stress, control diabetes, and not smoking. Coronary artery disease has an increase risk for age 40 years or older. It is more common in men than in women.
Cardiac markers are secreted from cells into the blood when the heart is abnormal. Therefore, cardiac biomarkers are important for the diagnosis of Ischemic heart disease and acute myocardial infarction. It is used in diagnosis, risk assessment, follow up as a treatment guide for coronary heart disease and heart failure or heart attack. As there are many possible caused for chest pain, tremor, sweating, and unconsciousness, treatment will also be different. Fast and accurate diagnosis can help physician treats patient accurately and promptly.
