Angioplasty has proven to be no more effective than drug treatment.
What is Heart Disease? Kristy Haugen The term heart disease is a very broad term.
Problems can arise within the heart muscle, arteries supplying blood to the heart muscle, or the valves within the heart that pump blood in the correct direction.
Understanding the differences between each disease of the heart can help with the confusing applications of the term heart disease. Coronary artery disease affects the arteries supplying blood to the heart muscle.
These coronary arteries harden and narrow due to the buildup of a waxy cholesterol, fatty substance referred to as plaque.
This plaque buildup is known as atherosclerosis. The increase in plaque buildup causes the coronary arteries to become narrower. This will cause blood flow to become restricted, decreasing the amount of oxygen delivered to the heart muscle.
Decreasing the amount of oxygen supplied to the heart muscle can cause angina chest pain and lead to a heart attack. Coronary artery disease over time can weaken the heart muscle contributing to heart failure and arrhythmias abnormal heart rhythms.
Coronary heart disease is another confusing type of heart disease. Coronary heart disease is not the same thing as coronary artery disease.
While coronary artery disease refers to the coronary arteries, coronary heart disease refers to the diseases of the coronary arteries and resulting complications. This includes such complications such as chest pain, a heart attack, and the scar tissue caused by the heart attack. Understanding this subtle difference between the two may impress your cardiologist.
Cardiomyopathy is a disease affecting the muscle of the heart. Cardiomyopathy can be genetic or caused by a viral infection. Cardiomyopathy can be classified as primary or secondary. Primary cardiomyopathy is attributed to a specific cause hypertension, congenital heart defects, heart valve disease.
Secondary cardiomyopathy is attributed to specific causes diseases affecting other organs. There are three main types of cardiomyopathy. Dilated cardiomyopathy is enlargement and stretching of the cardiac muscle.
Hypertrophic cardiomyopathy causes thickening of the heart muscle. Restrictive cardiomyopathy causes the ventricles of the heart to become excessively rigid causing blood flow to the ventricles to be difficult between heartbeats.
Valvular heart disease is a disease that affects the valves of the heart. Valves within the heart keep the blood flowing in the correct direction. Damage to valves can be caused by a variety of conditions leading to regurgitation or insufficiency leaking valveprolapse improper closing of the valveor stenosis narrowing of the valve.
Valvular heart disease can be genetic. Valvular heart disease can also be caused by certain infections such as rheumatic fever, and certain medications or radiation treatments for cancer.
The pericardium is a sac that encompasses the heart. Pericardial disease is inflammation pericarditisstiffness constrictive pericarditisor fluid accumulation pericardial effusion of the pericardium. Pericardial disease can be caused by many things such as occurring after a heart attack.
Congenital heart disease is a form of heart disease that develops before birth. Congenital heart disease is an extremely broad term. However, these diseases usually affect the formation of the heart muscle, chambers, or valves. A few examples include coarctation or a narrowing of a section of the aorta; atrial or ventricular septal defect is referred to as holes in the heart.
Congenital heart disease may be inherited heredityor caused by certain infections such as German measles contracted while pregnant.
However, researchers are currently studying factors that may cause congenital heart disease. Congestive heart failure is a type of heart failure in which leads to fluid buildup in the body. It is important to note that not all heart failure is congestive.When I was thinking of a written source of information on heart disease I thought I would try to find something in the encyclopedia.
Then, I looked online for sources of information on some web sites that I thought might have some information on them.
Hypercholesterolemia in Secondary Prevention of Coronary Heart Disease Introduction Figure 1: Symptoms of CHD Coronary heart disease (CHD) is a condition in which the lumen of the coronary arteries (blood vessels that supply blood and oxygen to the heart) are narrowed down.
Jun 24, · It is evident according to the data that it is Mr.
C is suffering from the threat of cardiovascular complaints such as congestive heart failure (CHF), coronary artery disease (CAD), diabetes.
stroke. Separately from all of that, Mr. C suffers from having the high risk for hypertension. With increased incidence of ischemic heart disease in cancer survivors, these studies indicate that cancer and its associated therapies are associated with an increased risk of symptomatic coronary .
of your heart, called coronary arteries. 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.
Survival Analysis of Cardiovascular Diseases Yuanxin Hu Washington University in St. Louis the thesis is not only for me, but also for my supervisor, my teachers, my classmates and my diseases (CVD), such as Coronary heart disease, congenital heart disease, stroke or cerebrovascular accident (CVA), congestive heart failure, peripheral.
