Step-by-step explanation:
Coronary artery disease (CAD), also known as coronary heart disease (CHD), is a condition where there is a reduction of blood flow to the heart muscle due to the build-up of plaque in the arteries of the heart. The prevalence of CHD is high, as it is the most common cardiovascular disease.
Common symptoms of CHD include chest pain or discomfort that may radiate to the shoulder, arm, back, neck, or jaw. Shortness of breath may also occur. In some cases, there may be no symptoms until a heart attack occurs.
Treatment for CHD can include lifestyle changes, such as a healthy diet and regular exercise, as well as medical interventions like medication to control blood pressure and cholesterol levels. In severe cases, procedures like angioplasty or bypass surgery may be necessary to restore blood flow to the heart.
