What are the different types of coronary heart disease?

What are the different types of coronary heart disease?

There are three main types of coronary heart disease: obstructive coronary artery disease, nonobstructive coronary artery disease, and coronary microvascular disease.

What is coronary heart disease means?

Coronary artery disease develops when the major blood vessels that supply your heart become damaged or diseased. Cholesterol-containing deposits (plaques) in your coronary arteries and inflammation are usually to blame for coronary artery disease. The coronary arteries supply blood, oxygen and nutrients to your heart.

What are the causes of coronary heart disease?

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 the difference between coronary heart disease and myocardial infarction?

Both angina and heart attack are a consequence of coronary artery disease. The symptoms of a heart attack (myocardial infarction/MI) are similar to angina. But, angina is a warning symptom of heart disease, not a heart attack.

What is the main function of coronary arteries?

Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function.

How is coronary heart disease diagnosed?

He or she may suggest one or more diagnostic tests as well, including:

1. Electrocardiogram (ECG). An electrocardiogram records electrical signals as they travel through your heart.
2. Echocardiogram.
3. Exercise stress test.
4. Nuclear stress test.
5. Cardiac catheterization and angiogram.
6. Cardiac CT scan.

What happens during coronary heart disease?

Coronary heart disease is the term that describes what happens when your heart’s blood supply is blocked or interrupted by a build-up of fatty substances in the coronary arteries. Over time, the walls of your arteries can become furred up with fatty deposits.

What are the 5 major causes of heart disease?

Risk factors

• Age. Growing older increases your risk of damaged and narrowed arteries and a weakened or thickened heart muscle.
• Sex. Men are generally at greater risk of heart disease.
• Family history.
• Smoking.
• Poor diet.
• High blood pressure.
• High blood cholesterol levels.
• Diabetes.

What prevents coronary heart disease?

Regular exercise will make your heart and blood circulatory system more efficient, lower your cholesterol level, and also keep your blood pressure at a healthy level. Exercising regularly reduces your risk of having a heart attack. The heart is a muscle and, like any other muscle, benefits from exercise.

What is the OM artery in the heart?

The obtuse marginal (OM) arteries sometimes referred to as lateral branches are branch coronary arteries that come off the circumflex artery. There can be one or more obtuse marginal arteries. It typically traverses along the left margin of heart towards the apex.
