Alcoholic cardiomyopathy is an alcohol-related heart disorder caused by excessive and habitual consumption of alcohol. Large quantities of alcohol have a toxic effect on heart muscle cells. Even a small amount of alcohol causes a measurable change in cell function.
In excess and over a period of time, alcohol can result in weakened heart muscle. The heart muscle becomes unable to pump blood efficiently. This condition can eventually lead to heart failure. Decreased heart function also affects the lung, liver and other body systems.
of alcoholic cardiomyopathy include:
- sensation of feeling the heart beat (palpitations)
- irregular or rapid pulse
- loss of appetite
- swelling in the legs and ankles
- shortness of breath
Complications with alcoholic cardiomyopathy can include congestive heart failure and cardiac arrythmias (irregularities).
Your healthcare provider will make a diagnosis based on your medical history, including your use of alcohol. He/she will probably conduct various tests as well, including checking for an enlarged liver. If the tests indicate heart failure and alcoholic cardiomyopathy is diagnosed, treatment will be planned accordingly.
One or more of the following treatments may be employed:
- digitalis or other medications to improve heart function
- diuretics to remove excessive fluid
- a low-salt diet
- complete abstinence from alcohol
The prognosis is mixed. Some patients follow a progressive downhill course. Occasionally, the heart muscle function may return to normal. If excessive alcohol consumption contributed to a weakened heart muscle, some patients have shown a marked improvement after they stopped drinking.
