In space and astronaut's heart may become weaker and also his/her bones from lack of use as there is little to no gravity acting on them as there would be on earth. To stop this happening astronauts are told to exercise and take special hormones.... but what else could they do?

firstly astronauts have nearly the same amount of gravity on them as on earth the difference is that there in free fall (gravity doesn't make people feel weight, the force pushing up on you from the ground is what makes you feel weight)
however to answer your question they cound go on a rigorous exercise schedual specially designed to maintain there heart and muscle strength

look up the tether system which is a theoretical way to provide space travellers with artificial graviity. Basically, the spacecraft is attached by a long cord to another and they spin around each other in a giant circle. If you are in one of the craft, you will be pushed against the outer edge, giving you gravity and making your muscles work normally.

One thing that has been talked about on long distance travel is to have two pods on a boom or a wire, then spinning the two around an common axis, thereby creating 'artificial gravity'.

Spend some time in a spinning tube that simulates gravity for the heart to pump against.
