Causes:

 

1.     Heart failure has three main causes:

 

2.     Structural  abnormalities  such  as malfunctioning  of  valves and the abnormal communication between chambers.

 

3.     Inadequate contractible ability of the myocardium.

 

Cardiac arrhythmias.

Other causes include:

 

1.     Pulmonary embolism; chronic  disease.

 

2.     Hemorrhage and aemia.

 

3.     Anesthesia and surgery.

 

4.     Transfusions or infusions.

 

5.     Fever, infection, pregnancy.

 

6.     Physical and emotional stress.

2.     Right-sided heart failure.

 


 

Left sided heart failure:

3.     Proxymal noctural dyspnea (Dyspnea after few hours of sleep)

 

4.     Dry and non-productive cough often worses in night.

 

5.     Fatigability- from low cardiac output, nocturia, insomnia, dysponea

 

6.     Tachycardia

 

7.     Chyene- stork respiration- A forms of irregular respiration.

 

Right sided Heart Failure:

 

Signs and symptoms

 

1.     Elevated pressures and congestion in systemic veins and capillaries.

 

2.     Peripheral edema

 

3.     Weight gain.

 

4.     Liver congestion

 

5.     Distended veins.

 

6.     Abnormal fluid on body cavity

9.     Weakness.

Diagnosis:

 

1.     ECG

 

2.     Chest X-ray

 

3.     Echo cordiography

 

4.     ABG studies

 

5.     Liver Function studies.

 

Management:

 

Medical:

 

1.     Rest and sleep

 

2.     Oxygen administration (refer practicals)

 

3.     Diuretics.

 

4.     Digitalis

 

5.     Vasodilator theraphy:

 

Surgical:

 

Heart transplant:

 

Nursing management:

 

1.     Place the patient  in a comfortable position

 

2.     Provide complete bed rest

 

3.     Provide bedside commode.

7.     Encourage deep breathing exercises every 1 to 2 hours.

 

8.     Daily weight.

 

9.     Passive range of motion exercises

11.                        Restrict sodium as directed.

 

12.                        Constipation may be avoided

 

Complication:
