A 35-year-old member asked:

is it possible for the body to reject a new heart after cardiac rehabilitation?

No: Cardiac rehab should have no impact on rejection after heart transplant.

Absolutely: The only thing that keeps the body from rejecting a new heart is your immunosuppressives (anti-rejection meds). Do not ever fail to take them as directed. There is no holistic, homeopathic, dietary, naturalistic [etc] alternative. Failure to take your drugs correctly will result in a waste of both the recipient's life as well as the donor's gift. :(.

How does HDL cholesterol affect your chance of developing heart disease?

High HDL lowers risk: You want your HDL to be as high as possible. A high HDL lowers the risk for coronary artery disease and other forms of vascular disease. The best way to raise your HDL is regular aerobic exercise, ideally 150 minutes /week, spread over 4-5 days.

Does having a slow heart beat cause dizziness?

Poor blood flow: The balance centers of the brain depend on good blood flow to the brain. If the heart is beating slowly or is not pumping enough blood into the brain, you will feel dizzy. First is to lie down so that the blood flow does not have to go uphill. Next is to lift the legs to be sure enough blood is getting into the heart. If the brain does not get enough blood flow, you can pass out and fall.

Vertigo?: The spinning sensation is called vertigo. Causes are either from ear or brain or side effect of drugs. If it occurs when lying still in bed, it is probably due to a disturbance in the brain. Pure vertigo is very rarely a seizure. More often it is due to poor blood flow to the back of the brain. Heart and blood pressure problems need to be considered. Migraine may be cause if rest is fine.

If I had a body scan today, when can I restart taking my hormone medicine?

Depends on hormones : I think that would depend on the type of hormone you are talking about and the scan you had. If you didnt get instructions then check with your doctor first. Did you have a thyroid scan? Was it a bone scan or a density scan?
