When coronary artery disease is highly suspected, there are various tests which may be done to help diagnose it. This includes an electrocardiogram (ECG), an exercise stress test, and most importantly, a coronary angiography (which is done to look at the coronary arteries themselves).
Once diagnosed, it is important to provide treatment to help slow down or stop the build-up of the atherosclerosis. The approach to managing CAD involves:
a. Lifestyle modification
• Have a healthy diet - limit fatty food and meat intake and eat more fruits and vegetables
• Limit alcohol intake
• Exercise regularly
• Maintain a healthy weight
• Avoid cigarette smoking
b. Medical treatment
• Medications used for lowering cholesterol levels, as well as those used to control blood pressure and diabetes
• Medications used to relieve symptoms such as chest pain
More invasive interventions, such as the use of stents or even surgery, may also be considered.
