Types of Heart Diseases

This feature is for informational purposes only and should not be used to replace the care and information received from your healthcare provider. Please consult a healthcare professional with any health concerns you may have.

When a physician first diagnoses you or a loved one with heart disease, you may feel overwhelmed and have a lot of questions. You may be confused by terms your doctor uses like “congestive,” “pulmonary,” or “cyanotic.” What’s the difference? Heart disease is heart disease, right?

All types of heart disease share common traits, but they also have key differences that may determine their progression and treatment. Becoming familiar with the type of heart disease you face can help you and your loved ones to better understand it and feel more in control of your next steps.


Angina causes pain or tightness in the chest area, creating a sort of “squeezing” sensation that sometimes resembles indigestion. This condition is not a disease in itself. It’s most often a symptom of coronary heart disease, in which the arteries supplying blood to the heart narrow and stiffen. Angina can also signify coronary microvascular disease, which is heart disease affecting smaller coronary arteries.

There are various types of angina, which all signal some sort of heart disease and should be checked out by your doctor.

Congenital Heart Disease

Congenital heart disease or heart defects are heart abnormalities present at birth. They occur while the fetus is developing in the uterus and may be caused by viral infections, medications, chemicals, alcohol, or other unknown causes.

These abnormalities may affect various parts of the heart, including the septum, valves, blood vessels, aorta, chambers, and more. Whatever the defect is, it may disrupt proper blood flow, causing symptoms like:

  • fatigue
  • shortness of breath
  • bluish skin
  • rapid heartbeat
  • swelling in the abdomen or around the eyes

Treatment varies depending on the severity of the defect but typically involves surgery.

Congestive Heart Failure

This condition is more common in older people and occurs when the heart can no longer pump blood to the rest of the body like it should. Doctors describe it as losing “pumping capacity.” The condition usually results from damage caused by a heart attack, high blood pressure, diabetes, coronary artery disease, cancer treatments, or other health issues and may result in excess fluid backing up into the lungs and other tissues. Congestive heart failure ranges from mild to severe, with symptoms such as:

  • weight gain
  • edema (swelling) in the abdomen, feet, ankles, and legs
  •  fatigue
  • dizziness
  • shortness of breath
  • eventual disability

Treatment involves medications, and other medical procedures and surgery for more severe cases.

Coronary Heart Disease

This type is the most common form of heart disease. It occurs when the arteries that supply blood to the heart become narrowed and hardened due to the buildup of plaque, known as “atherosclerosis.” Coronary heart disease is the leading cause of death in the United States for men and women.

Treatment depends on severity and involves keeping high blood pressure and high blood cholesterol under control, adopting lifestyle changes such as regular exercise, and in some cases, surgery options like angioplasty and bypass surgery.

Coronary Microvascular Disease

Also called MVD, small vessel disease, or cardiac syndrome X, this disease affects the heart’s tiny arteries. It damages the lining in the artery walls and causes them to narrow, increasing your risk for heart attack and heart failure. Symptoms include chest pain (angina), shortness of breath, and fatigue. Treatments mostly involve medications.

Cyanotic Heart Disease

This is a type of congenital heart defect that results in low blood oxygen levels throughout the body. It may be caused by a number of other heart defects like valve defects, hypoplastic left heart syndrome, Tetralogy of Fallot, or by infections or medications used during pregnancy. Symptoms may include:

  • hyperventilation
  • a bluish color to the skin
  • fainting
  • puffy eyes or face

Treatments typically involve surgery to repair the defect.

Hypertensive Heart Disease

Several heart problems may occur as a result of high blood pressure or “hypertension.” These problems are referred to collectively as “hypertensive heart disease.” Related problems may include:

  • coronary artery disease
  • heart failure
  • angina
  • heart attack
  • arrhythmias

Ischaemic Heart Disease

The word “ischaemic” means a “reduced blood supply.” Ischaemic heart disease is any heart disease that results in a reduced blood supply to the heart. Though there may be many causes, most incidences of this disease may be attributed to atherosclerosis, a narrowing of the arteries that supply the heart with blood. This disease is also referred to as coronary artery disease.

Inflammatory Heart Disease

This disease involves inflammation of the heart muscles or the surrounding tissues, which may be caused by bacterial, viral, or fungal infections, or by immune diseases. Symptoms usually include:

  • angina
  • shortness of breath
  • swelling in the feet and ankles
  • fatigue

Those most at risk include individuals who had a congenital birth defect or previous injury to the heart, intravenous drug users, and those with an artificial heart valve. Treatment depends on the extent of the damage to the heart muscle and typically involves medications or surgery.

Organic Heart Disease

This is an overall term that refers to any type of heart disease where the heart itself is affected, and doesn’t function as it should. This is due to a physiological problem, such as a deformity or inflammation.

Pulmonary Heart Disease

Also called “right-sided heart failure,” pulmonary heart disease occurs when a disease of the lungs affects the heart. Blood flow to the lungs may then slow down or become blocked, increasing blood pressure in the lungs. As a result, the right side of the heart has to work harder, which can lead to damage to the heart muscle itself.

Congestive heart failure may result. Pulmonary heart disease may be caused when a pulmonary artery becomes blocked or by respiratory diseases like emphysema. Treatments may involve medications, vasodilators, and oxygen therapy.

Structural Heart Disease

This term describes any condition that affects the structure of the heart itself. Usually, it refers to congenital heart defects, but it can also include abnormalities in the heart valves and vessels that develop later in life due to aging or disease.
