Healthy Heart Function and Work System

The main function of heart is to pump blood throughout the body. As a means of transportation in the body, blood carries the nutrients and oxygen needed by the body’s organs, while transporting residual substances. The heart and blood vessels form the cardiovascular system to ensure our survival.

A normal and healthy heart is supported by strong muscle tissues and works well in pumping blood. The heart that beats continuously in pumping blood, is able to drain more than 14,000 liters of blood per day.

The human heart is almost as small as the fist, divided into four parts, the right and left porch, and the right and left chamber. Each of these heart rooms is separated by a wall layer called a septum.

Blood is pumped through these parts. To ensure blood flow flow, there are valves that can open and close. All the valves are in charge of keeping the blood flowing in the right direction. There are four valves in the heart:

The mitral valve, located between the left porch and the left chamber. This valve normally has two valve leaves, hence also called the bikuspid valve.

The aortic valve, located between the left chamber and the aortic or the pulse trunk.

Tricuspid Valve, located between the right porch and the right chamber, and has three valve leaves.

The pulmonalist valve, located between the right chamber and the pulmonary artery.

Heart functions based on parts

Each part of the heart’s Anatomy has its own function. Here’s an explanation in more detail.

Right Porch

In the right foyer there is dirty blood. Gross blood is the blood of poor oxygen, enters the right foyer through the superior and inferior vein cava. From the right porch, the blood was pumped into the right chamber. At the heart of the fetus, there is a hole in the right foyer to allow blood to flow directly to the left foyer. It is important for fetal circulation, since the fetus’s lungs have not been able to work, so the fetus will take a clean blood-rich oxygen directly from the mother. After birth, baby’s lungs inflate and start functioning. The hole is closed and makes a boundary between the right and left foyer.

Right room

This is a responsible part of pumping dirty blood to the lungs so that carbon dioxide can be exchanged for oxygen through the respiratory process. Rooms are under the right foyer and next to the left room.
The dirty blood flowing through the right foyer will pass through the tricuspid valve to get to the right chamber. The blood is then pumped into the lungs through the pulmonary valve and runs through the pulmonary artery.

If this part of the heart is not functioning properly, so it can no longer pump efficiently, you could experience the right heart failure.

Left Porch

This section is responsible for receiving the blood clean from the lungs. Clean blood is blood that contains oxygen. Clean blood enters the left porch through a vein or pulmonary vein. This blood is then pumped into the left chamber through the mitral valve.

Left Chamber

The left chamber of the heart is located beneath the left porch and separated by mitral valves. The left chamber is the thickest part of the heart and is tasked with pumping clean blood throughout the body. The condition of high blood pressure can cause the left chamber muscles to enlarge and harden, due to the increased workload of the Left chamber of the heart in pumping blood. When this happens continuously, the function of the left chamber in pumping blood throughout the body can be interrupted.

Thus the importance of heart function, so we have to keep it by applying healthy lifestyle, among others, with a lot of vegetables and fruits, exercise routine, and which is mainly not smoke. If you experience impaired heart function, immediately consult a doctor for treatment.

Angioplasty, Life-Saving Heart Disease Sufferers

Coronary angioplasty is a procedure to open blockages or narrowing of the heart’s blood vessels. After undergoing angioplasty, the life expectancy of a person who has been or is at risk of heart attack may increase and the risk for subsequent cardiac arrest may diminish.

Angioplasty aims to increase blood flow to the heart. This mechanism is done by entering and inflating small balloons in the blocked portion of blood vessels to help broaden the channel. This procedure is actually included in the treatment of heart disease, especially in patients over 65 years.

Angioplasty is often combined with the placement of a small wire tube called a stent or ring. Some types of rings are coated with medicines that will help keep blood flow in the blood vessels open. Mounting rings aims to open the walls of blood vessels and prevent them from re-narrowed.

Role of angioplasty

In general, angioplasty is a procedure done to address the following health disorders.


To correct the obstruction of blood flow to the heart in patients with atherosclerosis, the symptoms include chest pain and shortness of breath. Atherosclerosis is a hardening of the walls of blood vessels occurring due to the buildup of fat plaque. Angioplasty is performed if with lifestyle changes or medications can not relieve symptoms.

Cardiac arrest

It can be done during a heart attack to open heart vascular blockage and reduce the risk of damage to the heart.

How does angioplasty do?

Medical history, results of physical examinations and supporting examinations will be considered by doctors before this procedure is conducted. The patient will undergo a coronary angiogram to determine the precise location of the narrowing of the blood vessels and know for certain that the narrowing or blockage that occurs can be handled by angioplasty.

Angioplasty is performed through cardiac catheterization, by making small incisions on the skin of the limbs, arms or wrists, so that a small catheter can be inserted into the blood vessels to the blocked or narrowed heart veins. The balloon at the end of the catheter will be inflated and flaned several times in the blood vessels, until the wall of the vessel is completely inflate. Then the catheter is removed. Chest pain can occur during the angioplasty process because when the balloon is developed, the blood flow to the heart is slightly obstructed. During the procedure, the patient will be drugged but still aware and the heart recording device will monitor the patient’s heart rate.

Once the angioplasty process is complete, the patient’s heart will be monitored in the hospital for some time, so that the patient must undergo hospitalization. When discharged, patients are usually advised to drink plenty of water and avoid strenuous activities. Try to always consume prescribed medicines, such as aspirin and the like.

The patient should immediately consult the doctor if: the area where the catheter is inserted is painful, becomes reddish, swollen, hot, or bleeding. Likewise, if it experiences shortness of breath, chest pain, or feeling faint.

This procedure cannot be done in all people who have heart disease. Some people who are experiencing the following conditions are advised not to undergo angioplasty:

  • Narrowing occurs in the main blood vessels that bring blood to the left heart.
  • Weak heart muscle.
  • Suffer from more than one disease that attacks blood vessels.
  • Suffer from diabetes.
  • There is more than one blockage of blood vessels.

In the above situation, it is better to do the heart bypass surgery (coronary), i.e. surgery performed to create a new channel using blood vessels from other parts of the body, so that the blood flow to the heart is smooth again.

Angioplasty also has risks

Although it is considered able to save patients with heart disease, angioplasty also has risks, namely:

  • Repeated narrowing of the arteries. Angioplasty that is done without stents can cause this opportunity up to 30 percent.
  • Can form a blood clot in the ring after the action finishes. This clumpy blood can clog the heart’s blood vessels and cause a heart attack.
  • Bleeding on the legs or arms at the catheter location is inserted.
  • Heart attack while undergoing procedure.
  • Kidney disorders Due to the contrast substance used when angioplasty and ring installation, especially in people who have already had a kidney disorder.
  • Heart vascular damage during the procedure.
  • The plaque can escape from the vascular wall when the catheter enters the blood vessel, and clog the blood vessels in the brain thereby causing the stroke.
  • Heartbeat that are too fast or too slow when undergoing angioplasty.
  • Allergic reactions to the contrast material used in the procedure.
  • Death from a heart attack or stroke.

Undergoing angioplasty does not mean heart disease has disappeared. This action will make the symptoms of shortness of breath and chest pain diminish, but can still reappear at any time. If the angioplasty is already able to cope with the disturbance that occurs in the heart, there is no need to do a heart bypass surgery that requires a large incision in the chest and a longer recovery stage.

So that you do not have to undergo angioplasty, it is important to maintain health by quitting smoking, maintaining ideal body weight, lowering cholesterol levels, and exercise regularly.
