ELIZABETH COHEN , CNN CORRESPONDENT: Keeping heart healthy is many times like alphabet soup so what do all the letters mean? Know your numbers or BP, LDL and HDL. BP is blood pressure, HDL and LDL are cholesterol.</s>DR. WARREN LEVY, PRESIDENT, VIRGINIA HEART: HDL which is your good cholesterol, that stands for high density lipo proteins and for men that should be above 40, for women above 50 and you should know your LDL, which is your low density lipo proteins, and those are the bad ones. They need to be under 100 for the general population.</s>COHEN: What does BMI stand for?</s>LEVY: IBMI stands for body mass index and it's a very simple way of calculating of the percentage of someone's body that is made up of fat and we have ranges we know are healthy and unhealthy. BMI less than 25 is healthy, above 25 you're overweight and you need to do something about it.</s>COHEN: And an EKG or ECG?</s>LEVY: EKG is actually the German abbreviation for electrocardiogram. In English we say ECG but it's an electrical measurement of the heart's activity.</s>COHEN: If you suffered from a TIA, should you be worried?</s>LEVY: A TIA is a transient ischemic attack. That's a stroke that almost happened. A TIA can be a warning sign you're at risk of having a stroke and that should never be ignored.</s>COHEN: All important things to know when it comes to your health. Elizabeth Cohen, CNN.
