The basic function of the heart is to pump the blood which is then circulated to the entire body. Heart failure occurs when the heart fails to pump enough blood to meet the body’s needs. 

Now a days heart failure has become a common ailment across the globe and is the root cause of many heart-related diseases.

Most common causes of heart failure:-

• Blockage of the arteries (coronary heart disease).
• Heart attack.
• High blood pressure.
• Heart valve problems.
• Diabetes.
• Lung diseases.
• Genetic problems in the heart muscles.
• Heart infections.
• Excessive intake of alcohol.

If severely blocked arteries are contributing to your heart failure, your doctor may recommend coronary artery bypass surgery. In this procedure, blood vessels from your leg, arm or chest bypass a blocked artery in your heart to allow blood to flow through your heart more freely.
