Dear marilyn, Thank you for your question. Although we cannot comment on specific medical treatment I can give you some general information on cardiomyopathy. It is usually diagnosed by history and an echocardiogram. Occasionally a heart muscle biopsy is performed. Symptoms are shortness of breath, swelling in the legs, chest discomfort and palpitations and increased fatigue.
Treatment is usually medical and in severe cases heart transplant.
About a third of patients get worse with some going on to transplant. Another third stay the same and are managed well with medical therapy and the rest get better. This will vary from doctor to doctor but generally every 6 months to a year. Someone with a decreased EF may feel more fatigued. Some people may die within months to years and others go on to have normal lifespans.
