Coronary artery disease (CAD) is caused due to blockage of arteries that supply blood to the heart muscles. The arteries become narrowed due to cholesterol and plaque within the walls. The blood flow through the arteries to the heart muscle is reduced in CAD. It can lead to angina pain (chest pain), a heart attack (myocardial infarction), weakness in the heart (heart failure) or changes in the normal heart rhythm.
Prognosis of coronary artery disease
Coronary artery disease has become a leading cause of death and health problems both in men and women. Depending on the severity of blockage of the artery, the symptoms may vary from angina pain (chest pain), a heart attack (myocardial infarction) to sudden cardiac arrest and death.
Advances in management of heart attack have significantly improved the prognosis of myocardial infarction. Many people with heart attack now survive and can lead a fairly normal life, but many people still die and therefore, it is important to prevent CAD.
Factors to improve prognosis of coronary artery disease
Prognosis or outcome of a person with coronary artery disease depends on many factors such as the severity of artery blockage, functioning of heart muscle and how many vessels are involved with blockages. Long-term prognosis or outlook of the disease, however, is significantly influenced by lifestyle of the patient, management of associated co-morbid conditions (such as hypertension, diabetes and cholesterol), adherence to medications and follow-up with the health care provider.
