Coronary artery diseases
This is the most common heart disease. The coronary arteries lie on the outside of the heart and carry blood to the heart muscle. Coronary heart disease arises when the coronary arteries narrowed or blocked. This usually results in angina and heart attack.
Angina
When the coronary arteries narrowed or blocked, the blood flow to the heart will be slow. Then the heart does not get enough oxygen and nutrients. This result in chest pain called angina.
Heart attack
Coronary artery disease causes decreased in blood flow to the heart muscle. If one or more coronary arteries become completely blocked, the heart becomes starved for oxygen and nutrients (ischemia). In a short time, injury to the heart muscle causes a heart attack.
Heart failure
Heart Failure is a condition when the heart is unable to pump an adequate amount of blood to the various parts of the body and eventually death.
Congenital Heart diseases
Congenital heart disease refers to a problem with the heart’s structure and function due to abnormal heart development before birth. Congenital means present at birth. While this disease present at birth, the symptoms may not be immediately obvious. No known cause can be identified for most congenital heart defects. Congenital heart diseases continue to be investigated and researched. Drugs such as retinoic acid for acne, chemicals, alcohol and infections (e.g. rubella) during pregnancy can contribute to some congenital heart problems.
Arrhythmia
Arrhythmia is a variation of heart rhythm, which cause the heart to beat too fast (tachycardia) or too slow (bradycardia) and to pump blood less effectively. Arrhythmias are very common, affecting millions of people worldwide. Arrhythmias are caused by either disruption of the normal electrical conduction system of the heart or heart disease. Problems can occur anywhere along the conduction system causing various arrhythmias. There can also be a problem in the heart muscle itself, causing the heart to respond differently to the signal or causing the ventricles to contract in an uncoordinated manner.
An arrhythmia occurs when:
· the heart’s natural pacemaker (sinoatrial node or SA node) develops an abnormal rhythm
· the normal conduction pathway is interrupted
· another part of the heart takes over as pacemaker
· disease in the heart muscle allows electricity to travel in a circuit generating a rapid and often dangerous heart rhythm
