,DEFINITION:
Congestive cardiac failure (CHF) is a medical condition in which
the heart is unable to pump sufficient blood to meet the body's needs.
This leads to an accumulation of fluid in the body and various
organs, including the lungs, legs, and abdomen.
Types of CCF
▪ There are two types of congestive cardiac failure:
▪ Left-sided heart failure: This type of CHF occurs when the left
ventricle is unable to pump enough oxygenated blood to the body. This
can cause fluid buildup in the lungs, leading to shortness of breath and
cough.
▪ Right-sided heart failure: This type of CHF occurs when the right
ventricle is unable to pump enough blood to the lungs, leading to fluid
buildup in other parts of the body, such as the legs, abdomen, and liver.
This can cause swelling in these areas and fatigue.
▪ Both types of CHF can occur simultaneously and can result in a vicious
cycle of fluid buildup and strain on the heart, leading to a decline in the
heart's ability to pump blood effectively.
,Systolic and diastolic dysfunctions are two different types of heart
failure that result from different problems with the heart's ability to
pump blood.
Systolic heart failure: This type of heart failure occurs when the heart's
ability to contract (systole) and pump blood is impaired. The heart
becomes weaker and less efficient at pumping blood, leading to a
buildup of fluid in the body.
Diastolic heart failure: This type of heart failure occurs when the heart's
ability to relax (diastole) and fill with blood is impaired. The heart
becomes stiff and less able to fill with blood, leading to a decrease in
the amount of blood pumped to the body and a buildup of fluid in the
lungs and other parts of the body.
Both systolic and diastolic dysfunctions can occur together, and they
can contribute to the development and progression of congestive heart
failure. Treatment of CHF often involves addressing both the systolic
and diastolic dysfunctions to improve the heart's ability to pump blood
and reduce symptoms.
, Causes of congestive heart failure (CHF) can include:
▪ Coronary artery disease: Narrowing of the arteries that supply blood to
the heart can lead to CHF.
▪ High blood pressure: Long-standing high blood pressure can weaken
the heart and lead to CHF.
▪ Heart attacks: A heart attack can damage the heart muscle and increase
the risk of CHF.
▪ Heart valve disease: Abnormalities or damage to the heart valves can
lead to CHF.
▪ Cardiomyopathy: This is a disease of the heart muscle that can weaken
the heart and increase the risk of CHF.
▪ Arrhythmias: Abnormal heart rhythms can reduce the heart's ability to
pump blood effectively and increase the risk of CHF.
▪ Chronic lung disease: Chronic lung diseases such as emphysema and
chronic bronchitis can increase the workload on the heart and increase
the risk of CHF.
▪ Infections: Certain infections, such as viral infections, can weaken the
heart and increase the risk of CHF
