heart disease behavioral risk factors Tobacco Use Tobacco use increases the risk of heart disease and heart attack. Cigarette smoking promotes atherosclerosis and increases the levels of blood clotting factors, such as fibrinogen. Also, nicotine raises blood pressure, and carbon monoxide reduces the amount of oxygen that blood can carry. Exposure to other people’s smoke can increase the risk of heart disease even for nonsmokers. Diet Several aspects of people’s dietary patterns have been

Chauhan, 2011). Homocysteine is an amino acid found in the body that helps to build and maintain tissue. High levels of homocysteine have been linked to endothelial damage to the blood vessels. This damage can lead to plaque formation, thus atherosclerosis can ensue (American Heart Association, 2012). Although there are many causes of hyperhomocysteinemia, research has shown that nutritional replacement has helped to lower the level. Folic acid and B vitamins have shown to decrease homocysteine

The Effects of Smoking The harmful substances in cigarette smoke include:- * Tar * Carbon Monoxide * Nicotine Short Term effects of tar * It settles in the lining of alveoli causing th diffusion distance to increase. * The chemicals in tar cause an allergic reaction. This forces the smooth muscle to contract and narrows the lumen. * It destroys the cilia so mucus cannot be removed. It also makes the goblet cells secrete more mucus. * Bacteria and Viruses build up

a blood clot (thrombosis) or the build-up of fatty deposits inside an artery leading to the artery hardening and narrowing (atherosclerosis).The four main types of Cardio vascular disease include * Coronary heart disease – This is when your conary arteries become narrowed by a gradual build-up of fatty material within their walls.The condition is called atherosclerosis and the fatty material is called atheroma.In time your arteries may become so narrow that they cannot deliver enough oxygen

Cardiovascular disease also called heart disease includes numerous problems, many of which are related to a process called atherosclerosis. Atherosclerosis is a condition that develops when a substance called plaque builds up in the walls of the arteries. This buildup narrows the arteries, making it harder for blood to flow through. If a blood clot forms, it can stop the blood flow. This can cause a heart attack or stroke (“What is Cardiovascular Disease (Heart Disease)?”). The purpose of this

Familial Hypercholesterolemia and Common Risk Factors Familial hypercholesterolemia is an inherited condition characterized by elevated levels of cholesterol in the blood, and is associated with LDL protein specifically (Huether & McCance, 2016). This condition can also have a genetic component, with both autosomal dominant and autosomal recessive forms of genetic mutations contributing to its formation (“Hypercholesterolemia”, 2017). These patterns of inheritance can influence the severity

include the following; • Aneurysm • Angina • Atherosclerosis • Cerebrovascular disease • Congestive Heart Failure • Coronary Artery Disease • Myocardial infarction (Heart Attack) • Peripheral vascular disease Atherosclerosis is a condition in which fatty material collects along the walls of arteries. This fatty material thickens, hardens (forms calcium deposits), and may eventually block the arteries. Atherosclerosis is a type of arteriosclerosis. The two terms are often

Overall, it was striking how much atherosclerosis we found," Dr. Gregory S. Thomas, director of nuclear cardiology education at the University of California, Irvine, and co-principal investigator of the study, said in a news release from the European Society of Cardiology. "We think of atherosclerosis as a disease of modern lifestyle, but it's clear that it also existed 3,500 years ago," he said. "Our findings certainly call into question the perception of atherosclerosis as a modern disease." The

Causes of cardiovascular disease While cardiovascular disease can refer to many different types of heart or blood vessel problems, the term is often used to mean damage caused to your heart or blood vessels by atherosclerosis (ath-ur-o-skluh-RO-sis), a buildup of fatty plaques in your arteries. This is a disease that affects your arteries. Arteries are blood vessels that carry oxygen and nutrients from your heart to the rest of your body. Healthy arteries are flexible and strong. Over time, however
