Cardiovascular Care Q & A

What is the cardiovascular system?

The cardiovascular system refers to your heart and circulatory system. These make up the network that provides blood to all the tissue and organs in your body. Each heartbeat pumps blood throughout the body, delivering oxygen and nutrient to all your cells.

The cardiovascular system is composed of the heart and blood vessels, including veins, arteries, and capillaries, which are branch-like blood vessels.

What are common cardiovascular conditions?

The most common cardiovascular conditions include:

Coronary artery disease

Coronary artery disease, or CAD, refers to the hardening and narrowing of the coronary arteries in your heart. This causes blockages in the vessels that carry blood to and from the heart and can lead to heart attacks, strokes, and peripheral vascular disease.

Heart attacks

Heart attacks occur if the blood flow to your heart is severely reduced or cut off. This generally happens when fat, cholesterol, or plaque have blocked the coronary arteries and caused a blood clot to form.


Arrhythmia occurs when your heart beats either too fast or too slowly. As a result, it may not pump blood adequately to your lungs, brain, and other organs.

Heart failure

Heart failure happens when your heart’s ability to pump blood is weaker than required. Consequently, the blood moves through your body too slowly and pressure on your heart increases.


Cardiomyopathy is a progressive condition that causes your heart to grow, thicken, and stiffen. Your heart lacks the power to pump blood effectively to the rest of your body. This can lead to arrhythmia or heart failure.

Peripheral artery disease

Peripheral artery disease, or PAD, occurs when plaque builds up in your peripheral arteries outside the heart. The plaque narrows the artery wall and limits the amount of the blood flow to the rest of your body.

What are common symptoms of cardiovascular diseases?

Some of the common overarching symptoms of cardiovascular diseases include:

  • Chest pain or pressure
  • Discomfort or pain in your arms, left shoulder, elbows, jaw, or back
  • Shortness of breath
  • Nausea
  • Fatigue
  • Lightheadedness
  • Cold sweats

The symptoms of cardiovascular disease are multifold and vary according to the condition you’ve been diagnosed with.
