Hi,
Cardiomyopathy may be an outcome of heart valve problems or heart tissue damage from a previous heart attack, as well as from other causes.There are three main types of cardiomyopathy: dilated, hypertrophic and restrictive, all of which affect the heart's muscle leading to difficult of pumping blood and delivering it to the rest of the body.
The outcome of heart failure is worse than that of most diseases, however, new therapeutic interventions using stem and other cell-based therapies are succeeding in the fight against it. Old drugs, with added potency are now being used again with success. There are plenty of researches done in the last few years that makes us more prepared of the expected outcome.

Take care and regards.
Sadly to say heart disease runs in the family and if both your parents had CHF you should be keeping a close eye on your heart. Stress test, Echocardiograms especially with the heart murmur. If you are a woman, the signs of a heart attack are different than men. Signs to look for are indigestion, dizziness, nausea or vomiting, weakness, fatigue, pain between shoulder blades, chest discomfort, shortness of breath. Sometimes the only sign is shortness of breath. For CHF right side heart failure swelling in legs and abdomen. Left side heart failure fluid backs up in the lungs producing either a dry cough or a white phelm production. My mom's mom and dad both had heart failure and all of her 10 brothers and sisters all have heart failure along with a lot of cousins.
Hope this helps. Take care and talk to your doctor.
