Heart failure refers to a part of the heart which is not functioning normally. In a congestive failure, the heart will be unable to pump blood sufficient enough to meet the requirements of different parts of the body.
A contraction of the heart is termed’ systole’ while its expansion is termed’ diastole’. During contraction, blood is pumped from the heart and during expansion; blood fills in to the ventricles of the heart.
Systolic failure is a condition wherein heart failure occurs due to problems with the contraction of the chambers in order to pump blood out from the heart. This is caused by weakening of the muscles of the heart.
Diastolic failure is a condition wherein heart failure occurs due to problems with the expansion of the chambers to fill in blood in to the heart. This is caused by stiffening of the heart muscles.
In both these conditions, the health of the heart is affected severely and insufficient blood reaches different parts of the body. Most people suffer a little of both these disorders but studies have revealed that more women suffer from diastolic heart failure as compared to men. Men stand higher risk of contracting systolic heart failure compared to women and even on its onset, the severity of systolic failure is lesser in women.
Some symptoms common to both these disorders are fatigue, persistent cough and congestion which will worsen on lying down, fluid retention in the feet, ankles and legs; wheezing, fast-paced heartbeat, bulged veins in the neck, pain in the chest or shortness in breath.
