A Problem in Heart – Cardiovascular Disease

Spread the love

Although every organ is important in our body but generally we talk about two organs; brain and heart. The heart is the most sensitive and soft organ in all living creatures. It pumps the blood to the lungs where it receives oxygen, collects the oxygen-rich blood from the lungs, and pumps it to all areas of the body through the network of arteries and veins called the cardiovascular system. It also removes carbon dioxide and other wastes also from the blood.

Human Heart Anatomy:

The human heart is roughly the size of a large fist and weighs between about 10 to 12 ounces (280 to 340 grams) in men and 8 to 10 ounces (230 to 280 grams) in women. It is located just behind and slightly left of the breastbone.

The heart has four chambers: two upper chambers (the atria) and two lower ones (the ventricles). The right atrium and right ventricle together make up the “right heart,” and the left atrium and left ventricle make up the “left heart.” A wall of muscle called the septum separates the two sides of the heart.

Works of Atrium and Ventricle:

  • The right atrium receives blood from the veins and pumps it to the right ventricle.
  • The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.
  • The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.
  • The left ventricle (the strongest chamber) pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous contractions create our blood pressure.

What is heart disease?

In general talking, we all are saying that those who are emotional and very soft from their hearts are very prone to get heart disease but it is not a hundred percent correct. Heart disease is very common now. Heart disease is the number one position cause of death globally. Today every age group of people gets affected with heart disease due to their lifestyle and the environment.

Heart disease is a condition that develops when a substance called plaque builds up in the walls of the arteries where the blood flows. This buildup narrows the arteries, making it harder for blood to flow through. If a blood clot forms, it can block the blood flow. This can cause a heart attack or stroke.

What are the different types of heart disease?

Coronary Artery Disease (CAD): In Coronary Artery Disease, the coronary arteries supply the heart muscle with nutrients and oxygen by circulating blood. The cholesterol plaques can narrow the arteries supplying blood to the heart which is the higher risk for complete blockage from a sudden blood clot and this causes the heart to receive less oxygen and nutrients. This blockage is called a heart attack. Sometimes it is called ischemic heart disease also.

Arrhythmia:Arrhythmia is an irregular heartbeat. It means your heart may not be able to pump enough blood to meet your body’s needs. There are various types of arrhythmias. The heart can beat too slow, too fast or irregularly. Some arrhythmias are benign, but others are life-threatening.

A normal human being heart rate is between 60 and 100 beats per minute (bpm). When the heart rate is less than 60 beats per minute are called Bradycardia and when the heart rate is too fast (more than 100 bpm) is called Tachycardia.

Heart Attack (Myocardial infarction): First of all we understand that there is a difference between heart attack and heart failure. A heart attack also is known as Myocardial Infarction. When the blood flow to a part of the heart is blocked by a blood clot and this clot cuts off the blood flow completely and then that part of the heart muscle dies due to no supply of blood and oxygen. This is a heart attack.

Heart Failure: It is also known as congestive heart failure. Heart failure is a condition when the heart does not pump blood around the body efficiently. This is due to the heart is either too weak or too stiff to effectively pump blood. There is a common misperception that heart failure means the heart stops beating. Heart failure means that the heart is not able to pump blood and oxygen to the body as required.

Congenital Heart Disease: Congenital heart disease is a term of some defects or deformities of the heart that are present at birth. For example, if there is a hole between the two chambers of the heart is called Septal defects. The flow of blood through various chambers of the heart is partially or totally blocked. This condition called Obstruction defects. A defect in the heart causes a shortage of oxygen around the body is called Cyanotic heart disease.

Heart Valve Disease: There are four valves in our heart. When heart valves don’t open enough to allow the blood to flow through as it should is called stenosis results. When the heart valves don’t close properly and thus allow blood to leak through, it’s called regurgitation. If the valve leaflets bulge or prolapse back into the upper chamber, it’s a condition called prolapse.


Heart disease is the leading in death causes around the world. Out of four people, one is suffering from some heart disease. The main cause of heart disease is our lifestyle. Neither we are eating a balanced diet nor doing exercise. We all are living a stressful life which causes hypertension and blood pressure. Our previous generation was happier than us. If you see the data, today’s rate of heart disease is high as compared to 30-40 years back. If we just disciplined our lifestyle, many diseases and health problems will not come near to us.
