Coronary Artery Disease

Aug 31, Heart (cardiovascular) disease (CVD, heart disease) is a variety of types of conditions that affect the heart, for example, coronary or valvular heart disease; cardiomyopathy, arrhythmias, and heart infections. Symptoms of heart disease include chest pain, sweating, nausea, and shortness of breath. Treatment for heart disease includes lifestyle changes, medication, and possibly surgery. Symptoms and Causes What are the symptoms of coronary artery disease? The most common ++symptom of coronary artery disease++ is angina. Angina is chest pain and can also be described as chest discomfort, heaviness, tightness, pressure, aching, burning, numbness, fullness, or squeezing.

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. 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. 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 what is the causes of coronary heart disease flow. Anginaor chest pain and discomfort, is the most common symptom of CAD. Angina can how to apply for medical internship in new zealand 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 tue. Symptoms of heart attack include.

Over time, CAD cases weaken the heart muscle. Learn the facts about heart diseaseincluding coronary artery disease, the most common type of heart 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. Cardiac rehabilitation rehab is an important program for how to play wind beneath my wings on piano 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.

What is coronary artery disease?

Coronary heart disease (CHD) is usually caused by a build-up of fatty deposits (atheroma) on the walls of the arteries around the heart (coronary arteries). The build-up of atheroma makes the arteries narrower, restricting the flow of blood to the heart muscle. This process is called atherosclerosis. Heart failure can result from many forms of heart disease, including heart defects, cardiovascular disease, valvular heart disease, heart infections or cardiomyopathy. Heart attack. A blood clot blocking the blood flow through a blood vessel that feeds the heart causes a heart attack, possibly damaging or destroying a part of the heart muscle. Dec 09, 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.

The coronary arteries are the blood vessels that carry blood to your heart.. Coronary artery disease is the narrowing or blockage of the coronary arteries. This condition is usually caused by atherosclerosis. Atherosclerosis is the build-up of cholesterol and fatty deposits called plaques inside the arteries.

These plaques can clog the arteries or damage the arteries, which limits or stops blood flow to the heart muscle. If the heart does not get enough blood, it cannot get the oxygen and nutrients it needs to work properly. This can cause chest pain angina or a heart attack. Healthy coronary arteries are smooth and elastic. The inside of these muscular hollow tubes are lined with a layer of cells called the endothelium.

The endothelium helps protect the vessel walls and keep the arteries working properly so blood can flow freely. Coronary artery disease starts when you are very young. Before your teen years, the blood vessel walls start to show streaks of fat. As you get older, the fat builds up, causing minor damage to your blood vessel walls.

With time, other substances that move through your blood stream, such as inflammatory cells, cellular waste products, proteins and calcium, stick to the vessel walls. These things combine with the fat and form plaque. If the hard surface cracks or tears, the soft, fatty inside is exposed. Platelets disc-shaped particles in the blood that help form clots move to the area, and blood clots form around the plaque.

The endothelium can also become irritated and stop working properly, which causes the artery to squeeze at the wrong times. This causes the artery to narrow even more. Sometimes, the blood clot breaks apart and blood can flow through the area again. Other times, the blood clot suddenly blocks the blood supply to the heart muscle, causing one of three serious conditions known as an acute coronary syndrome. Collateral Circulation. If the blockage in a coronary artery slowly gets bigger, new blood vessels may form to reroute blood around the blockage.

This is called collateral circulation. These new blood vessels may not be able to carry enough blood to the heart when you are active or under stress. The muscles in the legs cramp up because they need oxygen and nutrients. Your heart, which is also a muscle, needs oxygen and nutrients to keep working. When this happens, you may feel chest pain or other symptoms.

Ischemia happens most often when the heart needs extra oxygen, such as when you are active, eating, excited, stressed or exposed to cold. If symptoms stop within 10 minutes after you rest or take medication, you may have stable coronary artery disease stable angina.

But, the problem can get worse and you may have symptoms even when you are resting. You may have ischemia, or even a heart attack, but not have any symptoms.

This is called silent ischemia. This condition is more common in people with diabetes. An acute coronary syndrome is caused by a sudden blockage in the blood supply to the heart. Some people have symptoms before they have an acute coronary syndrome, but you may not have symptoms until the condition occurs. Some patients never have any symptoms. Changes caused by an acute coronary syndrome can be seen on an electrocardiogram ECG and in blood tests.

Unstable angina: This may be a new symptom or can happen if you have stable angina that changes to unstable angina. You may start to have angina more often, when you are resting, or it may be worse or last longer. The condition can lead to a heart attack. If you have unstable angina, you will need medication, such as nitroglycerin or a procedure to correct the problem.

But, a blood test will show that there is damage to your heart muscle. Angina is chest pain and can also be described as chest discomfort, heaviness, tightness, pressure, aching, burning, numbness, fullness, or squeezing.

It can be mistaken for indigestion or heartburn. Angina is usually felt in the chest, but you may also feel it in your left shoulder, arms, neck, back or jaw.

Other symptoms of coronary artery disease include:. At the first signs of a heart attack, call If the symptoms go away in 5 minutes and are new, worse or happening more often, call your doctor. If you have symptoms of angina and you have a prescription for nitroglycerin, stop what you are doing and rest.

Take one dose dissolve one tablet under your tongue or spray under your tongue. Wait 5 minutes. If you still have symptoms, call If you have chronic stable angina and you have symptoms, take one dose of nitroglycerin. If symptoms continue, take another dose. You can take 3 doses within 15 minutes. If symptoms continue after 3 doses, call Women can have different symptoms of coronary artery disease than men do. For example, many women who have a heart attack have :. If you have any of these symptoms, get medical help right away.

Call or have someone take you to the nearest emergency room. Do not wait! But, angina is a warning symptom of heart disease, not a heart attack. Angina Heart Attack Caused by a drop in blood supply to the heart due to the gradual build-up of blockage in the arteries. Caused by a sudden lack of blood supply to the heart muscle. The blockage is often due to a clot in a coronary artery. Does not cause permanent damage to the heart.

Can cause permanent damage to the heart muscle. Symptoms last a few minutes and usually stop if you rest or take medication. You may have chest pain or discomfort, shortness of breath, palpitations, fast heartbeat, dizziness, nausea, extreme weakness and sweating.

Symptoms are often triggered by strenuous activity, stress, eating or being in the cold. Symptoms usually last more than a few minutes and can come and go, and do not completely go away after taking nitroglycerin. Emergency medical attention is not needed. Call your doctor if you have not had symptoms before or if your symptoms have gotten worse or happen more often. Emergency medical attention is needed if symptoms last longer than 5 minutes. They may include:.

Your doctor will talk to you about the best treatment plan for you. Following your treatment plan will help reduce your risk of problems like heart attack and stroke.

The first step in treatment for coronary artery disease is reducing your risk factors. This involves making changes in your lifestyle. You may need to take medication to lower your cholesterol level or blood pressure or as treatment for other health conditions you have. It is important to take all medications as prescribed.

Ask your doctor if you have any questions about which medications you should take or how to take them. Common procedures are balloon angioplasty PTCA and stenting. The procedures are done with a long, thin tube called a catheter. It is inserted into an artery through a small incision and guided to the blocked area of the artery to clear the plaque. Your doctor will give you more information if you need an interventional procedure.

Your doctor will give you more information if you need CABG surgery. If traditional treatment options are not successful, your doctor may recommend other treatment options, such as:. This helps improve blood flow to the heart by helping create natural bypasses collaterals around blocked coronary arteries. Enhanced external counterpulsation is a possible treatment for patients with chronic stable angina who cannot have an invasive procedure or bypass surgery and do not get relief from medication.

There are several risk factors for coronary artery disease. The more risk factors you have, the more you are at risk of having heart disease. Your doctor can help you understand your individual risk factors and what you can do to lower your risk. Procedures to treat coronary artery disease increase blood supply to your heart, but they do not cure coronary heart disease.

You still need to follow the other parts of your treatment plan, including lifestyle changes and medications to help prevent your condition from getting worse. It is important to keep all follow-up appointments and have all tests your doctor orders.

These are needed so your doctor can keep track of your condition and how well your treatment is working. Doctors vary in quality due to differences in training and experience; hospitals differ in the number of services available.
