When alcohol consumption is continued, a condition known as cardiomyopathy, which affects the heart’s muscles and causes them to grow abnormally, might occur.

Alcohol use has more negative effects than positive ones, and long-term heavy drinking puts your heart in danger and may raise your risk of developing alcoholic cardiomyopathy. Dr. Pradeep Kumar D, Senior Consultant in Interventional Cardiology at Aster CMI Hospital in Bangalore, offers his insights on alcoholic cardiomyopathy and everything associated with it

A vast majority of people consider binge drinking to be harmless and most even believe that it is key to having a good time. Some people also don’t take alcohol as a drug and even believe that binge drinking is good for our heart too. However, alcohol consumption causes more harm than good and long-term excessive drinking poses a greater risk to the heart and may increase your chances of alcoholic cardiomyopathy.

What is alcoholic cardiomyopathy?

Excessive intake of alcohol often causes hypertension (high blood pressure) that weakens the heart muscles and makes it difficult for the heart to properly pump blood. This causes the heart to expand and become thin to hold more blood which affects the functioning of the blood and heart muscles. If hypertension is left untreated for too long, then it can result in heart failure.

In cases of prolonged intake of alcohol, Cardiomyopathy, a heart muscle disease develops in the heart causing the muscles of the heart to enlarge abnormally. If the cardiomyopathy is left unattended for too long, then the condition can turn potentially fatal and may raise the risk of irregular heartbeats which may trigger congestive heart failure. This condition is usually diagnosed among people of the age group 35 to 50 and men are found to be more prone to it than women.

People who have been heavily consuming alcohol for a period of 5 to 15 years or more are at a high risk of alcoholic cardiomyopathy. Men who consume over 14 drinks per week or 4 drinks per day and women who consume more than three drinks per day or seven drinks per week usually fall under the heavy drinking category and are likely to be more prone to alcoholic cardiomyopathy.

  3. Electrocardiogram (ECG) to detect any blockages in the heart and abnormalities in heartbeats.
  4. Treadmill stress test is performed to check if exercise is aggravating abnormal heart rhythms.
  5. Cardiac Catheterization is performed to check if the heart is forcefully pumping the blood in the body.
  6. CT scans are performed to assess the size and functioning of the heart and its valves.
  7. Blood tests are performed to assess the iron levels in the body and to check the thyroid, kidney, and liver function.
  8. To check if the disease is congenital, the doctors also perform a genetic test to check if the condition is hereditary in parents and siblings.

What are the treatment options for cardiomyopathy?
