Heart disease or cardiopathy is an umbrella term for a variety for different diseases affecting the heart. As of 2007, it is the leading cause of death in the United States,[1][2] England, Canada and Wales,[3] killing one person every 34 seconds in the United States alone.[4]

Coronary heart disease

Coronary artery disease is a disease of the artery caused by the accumulation of atheromatous plaques within the walls of the arteries that supply the myocardium. Angina pectoris (chest pain) and myocardial infarction (heart attack) are symptoms of and conditions caused by coronary heart disease.

Over 459,000 Americans die of coronary heart disease every year[5]. In the United Kingdom, 101,000 deaths annually are due to coronary heart disease.[6]

Cardiomyopathy

Cardiomyopathy literally means "heart muscle disease" (Myo= muscle, pathy= disease) It is the deterioration of the function of the myocardium (i.e., the actual heart muscle) for any reason. People with cardiomyopathy are often at risk of arrhythmia and/or sudden cardiac death.

Cardiovascular disease

Cardiovascular disease is any of a number of specific diseases that affect the heart itself and/or the blood vessel system, especially the veins and arteries leading to and from the heart. Research on disease dimorphism suggests that women who suffer with cardiovascular disease usually suffer from forms that affect the blood vessels while men usually suffer from forms that affect the heart muscle itself. Known or associated causes of cardiovascular disease include diabetes mellitus, hypertension, hyperhomocysteinemia and hypercholesterolemia.

Types of cardiovascular disease include:

Ischaemic heart disease

  • Ischaemic heart disease – another disease of the heart itself, characterized by reduced blood supply to the organs.

Heart failure

Heart failure, also called congestive heart failure (or CHF), and congestive cardiac failure (CCF), is a condition that can result from any structural or functional cardiac disorder that impairs the ability of the heart to fill with or pump a sufficient amount of blood throughout the body. Therefore leading to the heart and body's failure.

Hypertensive heart disease

Hypertensive heart disease is heart disease caused by high blood pressure, especially localised high blood pressure. Conditions that can be caused by hypertensive heart disease include:

Inflammatory heart disease

Disability-adjusted life year for inflammatory heart diseases per 100,000 inhabitants in 2004.[7]
     no data      less than 70      70-140      140-210      210-280      280-350      350-420      420-490      490-560      560-630      630-700      700-770      more than 770

Inflammatory heart disease involves inflammation of the heart muscle and/or the tissue surrounding it.

Valvular heart disease

Valvular heart disease is disease process that affects one or more valves of the heart. The valves in the right side of the heart are the tricuspid valve and the pulmonic valve. The valves in the left side of the heart are the mitral valve and the aortic valve.

Simple English

Heart disease is a general term that means that the heart is not working normally.

Babies can be born with heart disease. This is called congenital heart disease. If people get heart disease later, it is called acquired heart disease. Most heart disease is acquired.

Contents

Types of heart disease

The three most common types of acquired heart disease are:

  • Coronary Artery Disease (acronym CAD) – This is a problem with the blood vessels that deliver blood to the heart muscle. If these blood vessels get very small, or if they become blocked, blood cannot flow through them normally.Since less blood is supplied to the heart muscle the muscle cannot work at normal capacity. The heart muscle can become sick and weak. IHeart muscle can even die if blood flow stops. Blocked arteries in the heart are often the caused by smoking, high cholesterol, high blood pressure, diabetes and inherited traits from parents. All of these problems damage the lining of the heart's blood vessels and make them become narrowed or blocked completely.
  • Congestive Heart Failure (CHF) – This is a condition that means that the heart is not pumping at normal levels. Two common causes are a weak or sick heart muscle and the other is abnormal heart valves. The valves may not let enough blood through because they are too narrowed. Or the valve may "leak" and let blood flow backwards (the wrong direction) inside the heart. When the heart valves do not work normally, the heart muscle has to do extra work and it can become tired or fatigued.
  • Bad Heart Rhythms – This is a problem with electrical activity in the heart. This can make the heart beat too fast or too slow. Very bad heart rhythms may make the heart stop pumping blood. The heart needs a normal rhythm to pump the blood well. If the rhythm is too fast the heart may not have time for blood to enter the chambers,so there is not enough blood moving through the heart with each beat. If the heart is too slow there may not be enough contractions of the heart to supply the body with the blood that it needs.

Symptoms

A person can have heart disease and not feel sick. Some people with heart disease have symptoms. This is when there are changes or pain in the body to show a disease is there. Some symptoms of heart disease are:

  • Pain in the chest--the heart muscle is not getting enough flow to keep it going.
  • Trouble breathing--blood may back up into the lungs.
  • Palpitations (a feeling that the heart is beating too fast, too hard, or not regular).
  • Swelling of feet or legs--blood is backing up from in the lower body.
  • Feeling weak because the body and brain are not getting enough blood to supply them with oxygen.
  • Cyanosis (skin turning a blue colour) means that too little oxygen is in the bloodstream to supply the cells in the body.

Deaths

Heart disease is the biggest killer of both men and women in the United States, England, Wales and Canada. For example, heart disease causes 4 out of every 10 deaths in the United States, this is more than all kinds of cancer put together. Also, one person dies of heart disease every 34 seconds in the United States alone.

Congenital heart disease

Congenital heart disease refers to a form of heart problem that starts before birth (congenital). Congenital heart disease includes a large number of conditions. The formation of the heart before birth is a very complex and is sometimes abnormal. For example if a part of the main artery that comes from the heart is narrowed that is called coarctation of the aorta. There may be holes inside the heart which keep the blood from flowing normally inside the heart.Other congenital heart problems are caused by abnormal heart valves. In some cases, congenital heart problems are discovered at birth, other times the problems may not be detected until the person is an adult.
