Sometimes the heart makes peculiar sounds which can be heard distinctly by a doctor when he places his stethoscope over the chest. These are referred to as heart murmurs. It occurs when blood flows abnormally through the heart. Functional murmurs are innocent murmurs and can occur due to the defects outside the heart. Pathological murmurs are more dangerous and can occur due to dangerous conditions of the heart like narrowing of the arteries, defective valves, abnormal passages through which blood flows and leaking of valves.

A person who is always tired and short of breath may be a victim of congestive heart failure. There are several heart dysfunctions(In French maladie cardio) that trouble people.

Cardiomyopathy is a heart muscle disease. The myocardium stops functioning as well as it should. This is the kind of disease that goes unnoticed for a very long time before it gets detected.

Heart dysfunctions occur for a variety of reasons. In children, it could be because they are born with the disease. In adults, it may be acquired. It occurs due to age as well. Cardiomyopathy can lead to death.

Angina is a heart condition that is characterised by severe pain in the chest region. This happens when the heart is not getting enough blood. When part of the brain does not get enough blood due to a clot or burst blood vessel, it results in a stroke. Heart attack occurs when blood flow to the heart is blocked by a blockage in the arteries or veins.
