Coronary Artery Disease
(CAD; Coronary Atherosclerosis; Silent MI; Coronary Heart Disease; Ischemic Heart Disease; Atherosclerosis of the Coronary Arteries)
|Coronary Artery Disease|
|Copyright © Nucleus Medical Media, Inc.|
- Thickening of the walls of the arteries that feed the heart muscle
- Build up of fatty plaques within the coronary arteries
- Sudden spasm of a coronary artery
- Narrowing of the coronary arteries
- Inflammation within the coronary arteries
- Development of a blood clot within the coronary arteries that blocks blood flow
- Strong family history of heart disease
- Obesity and being overweight
- High blood pressure
- Inactive lifestyle
- High cholesterol , specifically, high LDL cholesterol and low HDL cholesterol
- Metabolic syndrome —a combination of high blood pressure, abdominal obesity, and insulin resistance
- Exercise or exertion
- Emotional stress
- Cold weather
- A large meal
- It is unrelieved by rest or nitroglycerin
- Severe angina
- Angina that begins at rest
- Angina that lasts more than 15 minutes
- Shortness of breath
Beta-Blockers, Calcium-Channel Blockers, and ACE-Inhibitors
Medications to Lower Cholesterol
- Percutaneous coronary interventions (PCI)—such as balloon angioplasty , in some cases, a wire mesh stent is placed to hold the artery open
- Coronary artery bypass grafting (CABG) —segments of vessels are taken from other areas of the body and are sewn into the heart arteries to reroute blood flow around blockages
Options for Refractory Angina
- Enhanced external counterpulsation (EECP)—large air bags are inflated around the legs in tune with the heart beat. The patient receives 5 1-hour treatments per week for 7 weeks. This has been shown to reduce angina and may improve symptom-free exercise duration.
- Transmyocardial revascularization (TMR)—surgical procedure done with laser to reduce chest pain
- Maintain a healthy weight.
- Eat a heart healthy diet that is low in saturated fat , red meat and processed meats, and rich in whole grains , fruits, vegetables, and nuts .
- Begin a safe exercise program with the advice of your doctor.
- If you smoke, talk to your doctor about ways to quit .
- Treat your high blood pressure and/or diabetes.
- Treat high cholesterol or triglycerides.
- Ask your doctor about taking a low-dose aspirin every day.
- Find ways to reduce stress.
