This suggests a direct or indirect role for ethanol-mediated oxidative stress in the heart (Jiang et al. 2012; Tan et al. 2012). Although results related to levels of alcohol consumption and stroke events are less clear, some conclusions can be drawn. Approximately 1 to 2 drinks per day may have no effect on or lead to a slight reduction in stroke events; however, greater daily alcohol levels increase the risk for all stroke events and incident stroke types.

When the heart doesn’t pump enough blood, this is known as congestive heart failure. Pack-a-day smokers have double the risk of a heart attack compared to nonsmokers, and the changes to your body start almost immediately after you quit, says Nicholas Ruthmann, MD, a cardiologist with the Cleveland Clinic. Eight hours after your last cigarette, your blood oxygen levels are already increasing, and within a few weeks, lung function improves by as much as 30 percent. Alcohol abuse has a toxic effect on many of your organs, including the heart.

Maintaining A Healthy Heart

Alcohol can increase heart rate temporarily, and repeated episodes of excessively high heart rate can lead to more serious cardiac conditions like heart failure and irregular heartbeat. American Heart Association News covers heart disease, stroke and related health issues. Not all views expressed in American Heart Association News stories reflect the official position of the American Heart Association. Researchers have found evidence of mitochondrial dysfunction or impaired bioenergetics related to alcohol consumption. This is not surprising, because mitochondria are a major target for free-radical injury. Dysfunctional mitochondria are less efficient, can become a source of ROS, and are more likely to initiate apoptosis (Marzetti et al. 2013).

Not only can alcohol cause damage to blood vessels in the body, but those who drink alcohol in excess are also more likely to develop conditions that can lead to complications. The American Heart Association added sleep to its most recent health checklist, and Dr. Farah says that it’s “imperative for cardiac health” to get eight hours so your body can reset and recover. “You’re allowing your body to rest and heal, and there’s alcohol enlarged heart a direct link with inflammation and plaque formation and lack of sleep,” says Dr. Farah. Sleep calms down the episodic inflammation process to minimize heart disease risk factors, she adds. “Alcoholic cardiomyopathy is a disease of the heart muscle, caused by the toxic effects of excessive alcohol consumption,” explains Professor Nik Patel, cardiologist and chairman of the academic board, Royal Society of Medicine.

Recovering from an alcohol-related heart attack

While the potential benefits of alcohol consumption remain unproven, there’s substantial evidence that it can harm health in a number of ways. Hypertrophic cardiomyopathy is a condition where the heart muscle walls are thickened. “Alcoholic cardiomyopathy is a very serious disease with significant implications,” says Patel. “Patients usually require medication to help the heart muscle recover.”

These factors combine to result in a lower rate of cardiovascular disease in people who drink moderate amounts of alcohol than in people who do not drink alcohol at all. In addition to the heart benefits, moderate alcohol intake can slightly lower your risk of type 2 diabetes, stroke and Alzheimer’s disease. Alcohol can have several positive effects on the body’s heart and blood vessels — the cardiovascular system. First, studies have found that drinking alcohol in moderation increases your high-density lipoprotein (HDL) or “good” cholesterol, which helps carry away and break down extra cholesterol in blood that could otherwise block your arteries. Alcohol thins your blood, too, making it less likely that your arteries will form a blood clot. Moderate alcohol intake can lower inflammation throughout your body, as well, and that can also have a positive effect on your cardiovascular system.

For many people with hypertrophic cardiomyopathy, medicines are enough to treat their condition. However, some people with significant symptoms don’t respond well to medicine. This procedure is usually very effective at reducing symptoms in these people. Some women might need alcohol septal ablation before becoming pregnant, even if their symptoms aren’t severe. On physical examination, patients present with non-specific signs of congestive heart failure such as anorexia, generalized cachexia, muscular atrophy, weakness, peripheral edema, third spacing, hepatomegaly, and jugular venous distention. ACM can also cause tachyarrhythmia (most common is atrial fibrillation).

• During busy, social times, it’s easy for our good habits to take a back seat.
• All told, drinking alcohol in excess is the third-leading cause of preventable death in the United States.
• The finding suggests that enlargement of the left atrium may be the factor linking alcohol to atrial fibrillation.
• Septal myectomy is another option for many people considering alcohol septal ablation.
• Those who develop AFib have a greater risk of developing other issues such as blood clots and strokes.
