Knowledge on Risk Factors of Coronary Heart Diseases among Middle Age

Coronary heart disease (CHD) is the most common type of heart disease and cause of heart attack. It is also known as coronary artery disease, atherosclerotic heart disease or ischemic heart disease. It results from the obstruction of blood flow through the coronary arteries to the heart muscle cells. Blood flow reduction resulting from coronary heart disease can cause angina and progress to myocardial infarction (MI) or sudden death if blood flow is not restored. CHD often results from atherosclerosis referring to the hardening of arteries due to the buildup of plague along the inner walls of the arteries of the heart. Incidence of CHD occurs in men between 35 to 45 years age. After the age of 65 the incidence of men and women equalizes, although there is evidence suggesting that more women are being seen with CHD earlier because of increased stress, smoking and menopause. Coronary heart disease risk factors are conditions or habits that raise the risk of coronary heart disease (CHD) and heart attack .These risk factors also increase the chance that existing CHD will worsen. The risk factors of coronary heart disease can be divided into modifiable and non modifiable risk factors.
