Heart Failure occurs when the heart fails to function properly. “Heart Failure”, also known as “Congestive Heart Failure (CHF)” doesn't mean the heart has failed or stopped working, it means one or more chambers of the heart failed to keep up with the volume of blood flowing through them.
The two types of heart dysfunction that lead to heart failure are:
- Systolic Heart Failure
Out of the two, this is the most common type. It occurs when the heart is weak and enlarged. The left ventricle muscle of heart loses some of its ability to contract or shorten due to which it fails to pump the amount of oxygenated and nutrient-filled blood the body needs.
- Diastolic Failure
This happens when the heart muscle becomes stiff and loses some of its ability to relax. As a result, the affected chamber finds trouble filling with blood during the rest period that occurs between each heartbeat. Sometimes the walls of the heart thicken, and the size of the left chamber remain normal or reduced.
It is very crucial for the left side of the heart to function properly. This is also the place where heart failure usually begins. Left atrium receives oxygen-rich blood from the lungs and pumps into the left ventricle. Once circulated through the body, blood is received in the right atrium and then travels to the right ventricle, which pumps it back into the lungs to be replenished with oxygen. When this right side loses its pumping power, blood can back up in the veins trying to return blood to the heart. Right heart failure does occur alone but is usually the result of left-side’s failure. When the left ventricle fails, the fluid backs up in the lungs. In turn, the pressure from excess fluid can damage the heart's right side, as it works to pump blood into the lungs.
According to Cardiac Surgery Hospitals in Chennai, Heart failure is a chronic, long-term condition that eventually gets worse. By the time most people notice and see a doctor regarding their symptoms, the heart goes far beyond normal.
This is why it’s necessary to have regular health checkups. In a routine physical examination, the doctors can detect signs of heart failure even before you experience symptoms.
People who experience any of these symptoms should immediately consult a doctor as soon as possible. Typical signs of heart failure include:
- Breathlessness/Shortness of Breath (Dyspnea)
- Chronic Cough or Wheezing
- Rapid or Irregular Heartbeat
- Lack of Appetite or Nausea
- Mental Confusion or Impaired Thinking
- Fluid Buildup and Swelling
- Rapid Weight Gain
These symptoms occur as the heart loses its strength and the ability to pump blood throughout the body. Blood in turn backs up and causes ‘congestion’ in other tissues of the body. Not only this, excess of fluid may pool in the failing portion of the heart and lungs. This is why heart failure is called "congestive." Prevention is better than cure. If you wait until the symptoms show up, the conditions may become life-threatening. If you experience any of these symptoms, consulttop Cardiologists in Chennai as soon as possible.
