Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis. What is coronary artery disease?Coronary artery disease (CAD) is the most common type of heart disease in the United States. It is sometimes called coronary heart disease or ischemic heart disease. For some people, the first sign of CAD is a heart attack. You and your health care team may be able to help reduce your risk for CAD. What causes coronary artery disease?CAD is caused by plaque buildup in the walls of the arteries that supply blood to the heart (called coronary arteries) and other parts of the body. Plaque is made up of deposits of cholesterol and other substances in the artery. Plaque buildup causes the inside of the arteries to narrow over time, which can partially or totally block the blood flow. This process is called atherosclerosis. What are the symptoms of coronary artery disease?Angina, or chest pain and discomfort, is the most common symptom of CAD. Angina can happen when too much plaque builds up inside arteries, causing them to narrow. Narrowed arteries can cause chest pain because they can block blood flow to your heart muscle and the rest of your body. For many people, the first clue that they have CAD is a heart attack. Symptoms of heart attack include
Over time, CAD can weaken the heart muscle. This may lead to heart failure, a serious condition where the heart can’t pump blood the way it should. What are the risks for coronary artery disease?Overweight, physical inactivity, unhealthy eating, and smoking tobacco are risk factors for CAD. A family history of heart disease also increases your risk for CAD, especially a family history of having heart disease at an early age (50 or younger). To find out your risk for CAD, your health care team may measure your blood pressure, blood cholesterol, and blood sugar levels. Learn more about heart disease risk factors. How is coronary artery disease diagnosed?If you’re at high risk for heart disease or already have symptoms, your doctor can use several tests to diagnose CAD. Heart tests and what they do.
What is cardiac rehabilitation and recovery?Cardiac rehabilitation (rehab) is an important program for anyone recovering from a heart attack, heart failure, or other heart problem that required surgery or medical care. In these people, cardiac rehab can help improve quality of life and can help prevent another cardiac event. Cardiac rehab is a supervised program that includes
A team of people may help you through cardiac rehab, including your health care team, exercise and nutrition specialists, physical therapists, and counselors or mental health professionals. How can I be healthier if I have coronary artery disease?If you have CAD, your health care team may suggest the following steps to help lower your risk for heart attack or worsening heart disease:
Can you live with a blocked right coronary artery?Coronary Artery Disease (CAD) is treatable, but there is no cure. This means that once diagnosed with CAD, you have to learn to live with it for the rest of your life. By lowering your risk factors and losing your fears, you can live a full life despite CAD.
Why is the right coronary artery important?The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm.
Which artery is the most common to have blockage?Although blockages can occur in other arteries leading to the heart, the LAD artery is where most blockages occur. The extent of the blockage can vary widely from 1% to 100%.
What happens when the right coronary artery is occluded?Occlusion of the right coronary artery (RCA) may cause infarction of the inferior wall of the left ventricle with or without right ventricular (RV) myocardial infarction (MI), manifested as ST-segment elevations in leads II, III, and aVF.
