How can CHD cause a heart attack GCSE answer?

If a coronary artery is blocked, the blood supply to part of the heart muscle is cut off. That part of the heart cannot continue to contract, causing a heart attack.

What is coronary heart disease a level biology?

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.

What is coronary artery disease for Class 11?

Coronary Artery Disease, which is also known as ischemic heart disease is a condition that occurs owing to the lipid deposition of plaque in coronary arteries. It is termed as atherosclerosis which in turn leads to blockages.

What are the treatments for coronary heart disease GCSE?

Treating cardiovascular disease

• Lower blood cholesterol by cutting down on fatty foods.
• Stop smoking and other recreational drugs.
• Learn to reduce stress by relaxing.
• Take regular exercise.
• Maintain a healthy Body Mass Index to avoid high blood pressure and reduce the strain on the heart.

What causes 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 prevents coronary heart disease?

Eat a healthy, balanced diet. A low-fat, high-fibre diet is recommended, which should include plenty of fresh fruit and vegetables (5 portions a day) and whole grains. You should limit the amount of salt you eat to no more than 6g (0.2oz) a day as too much salt will increase your blood pressure.

What are the types of coronary heart disease?

Types of Coronary Artery Disease

• Obstructive coronary artery disease, with narrowed or blocked vessels.
• Non-obstructive coronary artery disease, with arteries that inappropriately constrict or malfunction after branching into tiny vessels, or are squeezed by overlying heart muscle.

What is the largest coronary artery?

Structure and Function The left anterior descending artery (LAD) is the largest coronary artery runs anterior to the interventricular septum in the anterior interventricular groove, extending from the base of the heart to the apex.

What are the two types of coronary heart disease?

How does CAD develop?

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.

What are the 3 types of coronary artery disease?
