What are the symptoms of alcoholic cardiomyopathy?

Sometimes symptoms of cardiomyopathy do not show up until the condition is causing heart failure. You should call 911 or go to the emergency room if you experience extreme and lasting chest pain or cannot breathe. Less severe symptoms of cardiomyopathy include feeling weak and tired, loss of breath and energy, swelling in your midsection or legs, losing the desire to eat, and feeling irregularities in your heartbeats.
