Coronary artery disease (CAD) is a serious condition that can have life-altering complications if it is not treated. Lifestyle changes such as exercise and smoking cessation, which can reverse the disease or slow its progression, are usually recommended. Prescriptions, such as statins and beta blockers; specialized procedures, such as angioplasty; or surgeries, such as coronary artery bypass, may also be necessary, depending on the severity of your disease.
