Coronary heart disease (CHD) is a condition in which the blood vessels in the heart become narrowed or blocked by a build-up of fat. This can result in angina (chest pains) and heart attack. A stroke is when the normal blood supply to part of the brain is cut off, which can damage the area of the brain affected. CHD and stroke are the most. Heart disease and stroke can affect anyone, but some groups are more likely to have conditions that increase their risk for cardiovascular disease. Heart disease is the leading cause of death for people of most racial and ethnic groups in the United States, including African Americans, American Indians and Alaska Natives, and white people The heart is tasked with pumping blood where it pumps oxygenated blood to the body and deoxygenated blood to the lungs. The heart also has three main types of blood vessels that ensure the blood is transferred throughout the body. This test covers the B3 unit of AQA GCSE Biology on heart and circulation. Give it a try and see just how ready you are for the exams Coronary artery disease happens when the plaque buildup is in the arteries of your heart. It causes the arteries to become hardened and narrowed, which slows down or blocks the blood flow to your heart. Since your blood carries oxygen to your heart, this means that your heart may not be able to get enough oxygen On Heart Disease Coronary heart disease makes up 56% of all deaths relating to heart conditions. The heart pumps blood around the body carrying oxygen and other essential nutrients to the areas in the body where they are needed.1 Coronary Heart disease is when this process is restricted or interrupted

Coronary artery disease (CAD) does not usually cause symptoms until it becomes advanced. Subtle symptoms can include dizziness, indigestion-like sensations, fatigue, and lack of energy. More noticeable symptoms of CAD include shortness of breath and chest pain. These are all warning signs of a heart attack and you should seek medical attention. Coronary artery disease, also called CAD, coronary or atherosclerotic heart disease, is a serious condition caused by a buildup of plaque in your coronary arteries, the blood vessels that bring. LDL cholesterol tends to build up on the walls of the coronary arteries, increasing your risk of heart disease. HDL, often referred to as good cholesterol, carries cholesterol away from the cells and back to the liver, where it is broken down or passed from the body as a waste product

Coronary heart disease. Coronary heart disease (CHD) is when your coronary arteries become narrowed by a build-up of fatty material within their walls. These arteries supply your heart muscle with oxygen-rich blood. CHD is sometimes called ischaemic heart disease People who have more than one specific risk factor for coronary heart disease (CHD) might be at much greater risk for CHD than people with no risk factors. Take the quiz below: 1. Do you have high blood pressure (hypertension)? This condition strains the heart, and increases wear and tear on the blood vessels, making blockage more likely. 2 CORONARY CIRCULATION SURVIVORS Heart Muscle has own blood supply 1. Blood delivered to capillary beds in walls of heart through CORONARY ARTERIES Branch off from aorta where it leaves L. ventricle So heart has high-pressure supply of blood filled w/ Oxygen + Glucose 2.

Some of the common diseases of the heart are: Coronary artery disease (): The narrowing of the arteries supplying blood to the heart (coronary arteries). If the arteries develop complete blockage from a suddenly lodged blood clot, the condition is called a heart attack.; Stable angina pectoris: Chest pain due to insufficient blood supply to the heart from doing strenuous physical activity

Coronary heart disease is self inflicted

Ischemic heart disease occurs if plaque builds up in the arteries that supply blood to the heart, called coronary arteries. Over time, heart disease can lead to chest pain, heart attack, heart failure, arrhythmias, or even death. Smoking is a major risk factor for heart disease Cholesterol is a risk factor for heart disease, but recent research suggests the connection may be more complex than just limiting dietary cholesterol to a specific quantity each day. Learn about. This reduces the ability of the blood to carry oxygen, putting strain on the circulatory system and increasing the risk of coronary heart disease and strokes.Lung cancerCarcinogens are substances that cause cancer. Tobacco smoke contains many carcinogens, including tar increase of coronary heart disease. • Unsaturated fat is often described as 'good fat' and can be found in olive oil or sunflower oil, olives and avocadoes.
