What are Cardiovascular Diseases-Healthcoco

The cardiovascular system (or circulatory system) is like a transport system for our body. It provides a system where oxygenated blood from the heart and lungs is transferred to the rest of the body through arteries, and deoxygenated blood is taken back through veins. Cardiovascular diseases (CVD) are a group of diseases that affect the heart or blood vessels. They are generally caused due to deposits of fat and plaque around arteries. This hardens or narrows the arteries, leading to less blood flow. Healthcoco offers lab tests for the same at very reasonable prices.

There are four main types of CVD:

  • Coronary heart diseases

  • Strokes

  • Peripheral arterial diseases

  • Aortic diseases

Coronary heart diseases

Like all the other organs, the heart requires a continuous supply of oxygen to survive and function. Coronary arteries do transportation of oxygenated blood to the heart muscle. When the supply of this oxygen-rich blood is either blocked or reduced, coronary heart diseases are caused. The blockage or reduction in supply is due to a build-up of fatty substances (atheroma) in the coronary arteries. The build-up of atheroma makes coronary arteries narrow and hence makes it difficult to supply oxygenated blood. Any disorder or disease of the coronary arteries can have a major impact on health and may lead to angina, a heart attack, and even death.


Stroke is considered a heart disease because it is related to blood flow. However, a stroke is caused due to reduction or stoppage of blood flow to the brain rather than to the heart. If not treated fast, parts of the brain can die or suffer damage due to lack of oxygenated blood.  A stroke is a medical emergency and quick treatment is crucial. 

Peripheral arterial diseases

Peripheral artery disease (PAD) is also known as peripheral arterial disease. Like stroke, they are also caused by a buildup of fatty deposits in the arteries. The difference is that they are located in the blood vessels outside the heart and brain. PAD affects the blood flow to the tissue by making them narrow, restricting the blood flow to the arms, kidneys, stomach, and most commonly, the legs. The most common symptom is pain, which becomes worse as the circulation becomes more limited. Stopping the consumption of Tobacco, exercising, and having a healthy diet are often successful treatments. Medication or surgery can help if these treatments don’t solve the problem. 

Aortic diseases

Aorta is the largest artery in the body. It gives access to the oxygen-rich blood to our body.  The aorta can split (dissection) or dilate (aneurysm) when affected by the disease. In both the cases, the rupture may have baneful results.  In an aortic dissection, the inner layer of the aorta tears. It is a medical emergency. 

In an aortic aneurysm, the walls of the aorta weaken and have a balloon-like bulge. This can cause rupture and lead to internal bleeding. 

The aortic disease includes:

  • Aortic Valve Disease 

  • Ascending Thoracic Aortic Aneurysms

  • Aortic Arch Aneurysms

  • Descending Thoracic Aortic Aneurysms

  • Abdominal Aortic Aneurysms

  • Aortic Dissection

  • Atherosclerotic Aortic Disease

Cardiovascular diseases are a major reason for deaths worldwide. Still, lifestyle changes like regular exercising (brisk walking) and a healthy diet (DASH diet, less salt consumption) can help to a large extent. These measures will not only prevent development but also reduce the further progression of cardiovascular diseases.
