Coronary artery disease

inactive can lead to diseases such as coronary heart disease, osteoporosis, and colon cancer, according to Harvard researchers. Coronary heart disease, or Atherosclerosis, is a disease in which plaque, a waxy substance, is built up in the coronary arteries. Plaque can harden or break open after a while. Hardened plaque partially blocks the arteries and reduces the flow of oxygen-rich blood to the heart. Ruptured plaque can lead to blood clots which can completely block the artery. Symptoms…

system, principally cardiac disease, vascular diseases of the brain and kidney, and peripheral arterial disease. The causes of cardiovascular disease are diverse but atherosclerosis and/or hypertension are the most common. In addition, with aging come a number of physiological and morphological changes that alter cardiovascular function and lead to increased risk of cardiovascular disease, even in healthy asymptomatic individuals. Heart attacks and strokes are usually acute events and are mainly…

organ that pumps blood throughout our bodies through veins, arteries and capillaries. These blood vessels supply our other major organs and tissue with oxygen and carries away the carbon dioxide and waste.

There are four types of Angina: • Stable • Unstable •…

Acute coronary syndromes is an umbrella term that includes several cardiac ischemic events.1 The broad term of ACS entails ST segment elevation-ACS (STE-ACS) and non-ST segment elevation ACS (NSTE-ACS) based on the initial electrocardio- gram(ECG) finding.4 ACS usually occurs as a sudden reduction in blood flow to the coronary arteries due to rupture of the atherosclerotic plaque, which subsequently leads to myocardial ischemia or/and infarction.1, 2, 3 The American Heart Association (AHA)…

Cardiovascular disease is one of the most prevalent chronic diseases and the leading cause of death in the United States. Every year about 1 million Americans die due to cardiovascular related problems, which is about 42% of total death per year. Cardiovascular disease is the disease of heart and vascular system of the human body that includes narrowing down or blocking of blood vessels (arteries, veins and capillaries) that can lead to range of diseases such as coronary artery disease,…

oronary heart disease (CHD) is also known for having alternative names such as coronary artery disease (CAD) and Arteriosclerotic heart disease. It is a condition wherein the plaque starts building up inside the coronary arteries which supply the heart muscle with blood and oxygen. The process of plaque building up is called atherosclerosis. This plaque is made up of calcium, fat, cholesterol and other substances that are usually found in the blood. The plaque narrows down the arteries and…

Atherosclerosis What is Atherosclerosis? Atherosclerosis is thickening, or hardening of the arteries, which can lead to plaque build up. This build up causes the arteries to narrow and makes it harder for the blood to flow. Sometimes a clot will form and stop the flow completely, causing a stroke or heart attack. Plaque is made up of cholesterol, fatty substances, cellular waste products, calcium and fibrin. Atherosclerosis begins at a young age and progressively increases with age, it can…

size of your fist Heart disease is the number one killer in the United States. The term Heart Disease is used to label a range of diseases that affect the heart; heart failure and coronary artery disease- are a few of many serious heart problems. According to the National Heart, Lung, and Blood Institute, their research suggest that heart disease begins with damage to the lining and inner layers of the coronary (heart) arteries. The buildup of plaque in the heart arteries may even start as early…

Coronary heart disease and angina • Angina is pain or discomfort that comes when your heart does not get enough oxygen. Angina is usually a symptom of a heart problem known as coronary heart disease (CHD), also called coronary artery disease (CAD)1 • • Your heart is a muscle. It pumps oxygen-rich blood to your whole body. Your heart also needs oxygen to work. Blood vessels called coronary arteries carry blood with oxygen to your heart. • • In healthy coronary arteries, blood flows freely to…

Chronic diseases continue to become more prevalent in society, the problems associated with each chronic disease continue to change and advance. Continuous changes in disease processes complicates the treatment and disease management because every patient has a different care plan. This impacts the health profession because these complicated cases require more research and education that doctors and nurses may not have experience with before. The major issue with the rise of chronic diseases is…
