Risk factors leading to Heart Disease
Coronary Heart Disease or Coronary Artery Disease or Ischaemic Heart Disease is one of the leading cause of morbidity and mortality throughout the world. It is on a constant rise now in India too. The main cause of this disease is the deposit of cholesterol and fat in the inner smooth lining of the blood vessels (coronary arteries, which supply blood to the heart), resulting in blockages and obstruction in blood flow.
Certain condition and lifestyle habits are now recognised and documented as being responsible for the deposit of cholesterol and fat in blood vessels as well as the increase in the rate at which they are being deposited. These are referred to as risk factors.
The risk factors are the reasons which lead to aggravating the deposit of cholesterol of fat in the coronary arteries. All the factors which are important in the development of coronary heart disease have been classified into two categories :
1. Modifiable risk factors :
In this group come to those risk factors which can be altered and prevented so that the further progress of heart disease can be arrested.
The modifiable risk factors are:
2. High levels of blood cholesterol
3. High blood triglyceride level
4. A low blood HDL level
5. Lack of antioxidants in the diet
6. High blood pressure
7. Diabetes mellitus
8. Obesity or overweight
9. Sedentary lifestyle or lack of physical activity
10. Smoking or tobacco consumption
2. Non-Modifiable factors :
There are three risk factors which cannot be altered such as age, gender and heredity.
