About Lipids / Cholesterol

 

What is a risk factor ?

A risk factor is a condition that increases your chance of getting heart disease or having a heart attack.

 

How does raised cholesterol levels cause heart attack ?

bullet

When there is too much cholesterol (a fat like substance) in your blood, it builds up in the walls of your arteries.

bullet

Over a time, this build up causes "hardening of the arteries' so that arteries become narrowed and blood flow to the heart is slowed down or blocked.

bullet

The blood carries oxygen to the heart, and if enough blood and oxygen cannot reach your heart, you may suffer chest pain.

bullet

If the blood supply to a portion of the heart is completely cut off by a blockage, the result is a heart attack.

bullet

Your blood cholesterol level has a lot to do with your chances of getting a heart disease.

bullet

 High blood cholesterol is one of the major risk factor for heart disease.

 

Why should blood cholesterol level be checked without any symptoms ?

bullet

High blood cholesterol itself does not cause symptoms, so many people are unaware that their cholesterol level is too high.

bullet

It is important to find out what your cholesterol numbers are because lowering cholesterol levels that are too high lessens the risk for developing heart disease and reduces the chance of a heart attack or dying of heart disease, even if you already have it.

bullet

Cholesterol lowering is important for everyone-younger, middle age and older adults, women and men; and people with or without heart disease.
 

What do your cholesterol numbers mean?

bullet

Every one age 20 and older should have their cholesterol measured at least once every 5 years.

bullet

It is best to have a blood test called a "lipoprotein profile " to find out your cholesterol numbers. This blood test is done after a 9-12 hour fast and gives information about your:

  1. Total Cholesterol

  2. LDL (Bad cholesterol) The main source of cholesterol buildup and blockage in arteries.

  3. HDL (Good cholesterol) helps keep bad cholesterol from building up in the arteries.

  4. Triglycerides-Another form of bad fat in your blood.

bullet

If it is not possible to get a lipoprotein profile done, knowing your total cholesterol and HDL cholesterol can give you a general idea about your cholesterol levels.

bullet

If your total cholesterol is 200 mg/dL or more, or if your HDL cholesterol is less than 40 mg/dL, you will need to have a lipoprotein profile done.

bullet

HDL (Good) cholesterol protects against heart disease, so for HDL, higher the numbers are better. A level less than 40 mg/dL is considered a major risk factor because, it increases your risk for developing heart disease.

bullet

HDL levels of 60 mg/dL or more help to lower your risk for heart disease.

bullet

Triglycerides can also raise heart disease risk. Levels that are borderline high (150-159 mg/dL) Or high (200 mg/dL or more) may need treatment.

 

What is your risk of developing heart disease or having a heart attack?

bullet

In general, the higher your LDL level and more the risk factors you have (other than LDL), the greater your chances of developing heart disease or having a heart attack.

bullet

 Some people are at high risk for developing heart disease because they have diabetes (which is a strong risk factor) or a combination of risk factors for heart disease.
