It can become weak and pump blood less efficiently, causing the lungs to become congested instead of It's weak and holds fluids, causing it to beat irregularly and making the lungs get congested. Sometimes you can help prevent this by taking care of your heart -- eat healthy, exercise, and watch your weight. Otherwise, drugs and devices like pacemakers can help treat the condition.

    Answer 1/12

    When was the first successful human heart transplant?

    • You answered:
    • Correct Answer:

    On Dec. 3, 1967, South African cardiac surgeon Christiaan Barnard transplanted a heart from a 25-year-old who died in an accident into a 53-year-old man. The man died 18 days later of pneumonia, but Barnard considered the transplant a success. It was followed days later by the first American transplant at Stanford University in California. Now, thousands of heart transplants are done worldwide each year, with roughly 75% of patients surviving for more than 5 years.

    • You answered:

    Answer 1/12

    A heart can sometimes fix itself.

    • You answered:
    • Correct Answer:

    Scientists used to believe that once an organ is grown it doesn't make any more cells. But research has found that the heart and other organs keep making new cells, at least in limited amounts. They could replace damaged ones caused by, for example, a heart attack.

  • Question 1/12

    Be careful of airport security machines if you have a pacemaker.

  • slide image
    Answer 1/12

    Be careful of airport security machines if you have a pacemaker.

    • You answered:
    • Correct Answer:

    Metal detectors likely won't cause problems for people with pacemakers. But the Transportation Security Administration asks that people with a pacemaker, defibrillator, or other internal medical device not go through the metal detector. Instead, ask for a pat down or to go through the imaging-technology scan.

     

    The American Heart Association suggests avoiding machines with powerful magnets, like MRIs. Some MP3-player headphones shouldn't be kept near a pacemaker either.
