Knowing Coronary Artery Disease - Symptoms and Causes
Coronary Artery Disease - Symptoms and Causes
Coronary artery disease is the disease in which the major blood vessels (coronary arteries) that supply blood, nutrients and oxygen to your heart get damaged or disease stricken. It is mostly caused due to the coronary artery getting plagued or inflamed. The consequent reduction in blood flow to the heart causes the various symptoms of coronary artery disease like angina (chest pain), short breath etc.
Symptoms:
Here is a list of a few symptoms that help in identification of the coronary artery disease.
1. Angina - Pressure or tightness may be felt in or near the area of the chest that results in pain. It is mostly felt in the middle or left side of the chest.
2. Shortness of breath - Another symptom of coronary artery disease is short breath, fatigue and a feeling of exertion.
3. Heart attack - Complete blockage of the coronary artery results in a heart attack that is a prominent symptom of coronary artery disease. A person may feel heavy pressure in the chest, pain in the shoulder or arm, sweating etc. prior to getting a heart attack.
Causes:
Coronary artery disease occurs when damage or injury is done to the inner layer of the coronary artery. This damage causes plaque, which are deposits made of fat, cholesterol and other cellular waste materials to accumulate near the damaged area of the artery. This process is known as atherosclerosis.
The various causes that result in coronary artery damage are listed below.
- Smoking
- High blood pressure
- Diabetes
- High cholesterol
- Obesity
- High stress
- Physical inactivity
