Beer And Heart Murmurs: What You Need To Know

Alcohol has been linked to a reduced risk of heart attacks, but only when consumed in moderation. For men, this means one to two drinks a day, and for women, it's best to stick to one. However, heavy drinking can lead to heart failure and other severe problems. Alcohol-induced cardiomyopathy is a condition where the heart changes shape due to long-term heavy alcohol use, and it can lead to heart failure and even death. This condition is rare and usually only affects long-term alcoholics.

Alcoholic cardiomyopathy: A condition where the heart changes shape due to long-term heavy alcohol use

Drinking alcohol is linked to a number of poor health outcomes, including heart conditions. Alcoholic cardiomyopathy (ACM) is a condition where the heart changes shape due to long-term heavy alcohol use. This condition is characterised by ventricular dilation and impaired cardiac function, with the left ventricle being particularly affected. The condition can lead to heart failure and severe problems.

ACM is caused by chronic alcohol consumption, which is defined as drinking more than the recommended amount. The specific threshold for developing ACM is unknown, but drinking more than 80 grams of alcohol per day for at least five years significantly increases the risk. The condition is more common in men, especially those aged 30-55, and occurs in 1-2% of all heavy alcohol users.

The exact mechanisms by which alcohol causes ACM are not fully understood, but it is thought to involve oxidative stress, mitochondrial dysfunction, apoptosis, and altered fatty acid metabolism and transport. These processes lead to damage and dysfunction of the heart muscle cells, resulting in impaired contraction and dilation of the ventricles.

The clinical features of ACM include symptoms such as chest pain, fatigue, lightheadedness, heart palpitations, and swelling in the legs and ankles. The condition is diagnosed based on a person's medical history, physical examination, and the results of diagnostic tests such as echocardiograms and electrocardiograms.

The treatment for ACM involves complete abstinence from alcohol, along with supportive care and medications to manage heart failure and related complications. In some cases, surgery or a heart transplant may be necessary. Improving care coordination among healthcare professionals is important for optimising outcomes for patients with ACM.

In summary, alcoholic cardiomyopathy is a serious condition that can occur due to long-term heavy alcohol use. It is characterised by ventricular dilation and impaired cardiac function, leading to heart failure and other severe problems. Treatment involves alcohol abstinence and medical management.

Heart murmurs: Sounds made by turbulent blood flow through the heart, which can be harmless or a sign of a serious condition

Heart murmurs are sounds made by turbulent blood flow through the heart. They can range from harmless to a sign of a serious heart condition.

Heart murmurs are sounds—such as whooshing or swishing—made by rapid, choppy (turbulent) blood flow through the heart. They can be heard with a stethoscope. A typical heartbeat makes two sounds like "lubb-dupp" when the heart valves are closing.

Types of heart murmurs

Heart murmurs can be present at birth (congenital) or develop later in life (acquired). Some heart murmurs are harmless (innocent), meaning they are not a sign of heart disease and don't need treatment. Other heart murmurs may be a sign of a serious heart condition.

Causes of heart murmurs

Harmless (innocent) heart murmurs

A person with an innocent murmur usually has a typical heart. Innocent heart murmurs are common in newborns and children. Things that might change blood flow and cause an innocent heart murmur include:

• Lack of healthy red blood cells that carry oxygen to body tissues (anaemia)
• Overactive thyroid (hyperthyroidism)
• Phases of rapid growth, such as adolescence
• Physical activity or exercise

Innocent heart murmurs may go away over time, or they may continue for life without causing serious health problems.

Worrisome heart murmurs

In children, worrisome murmurs are usually due to a problem with the heart's structure that's present at birth (congenital heart defect). Congenital causes of worrisome heart murmurs include:

• Holes in the heart, such as atrial septal defect and ventricular septal defect
• Cardiac shunts, which are heart structure problems that cause irregular blood flow between the heart chambers or blood vessels

In adults, worrisome heart murmurs are usually due to heart valve problems that develop later in life (acquired heart valve disease). Things that can damage the heart valves include:

• Calcium deposits, which can cause heart valves to become stiff, narrow, or not close completely
• Infection of the inner heart lining and valves (endocarditis)
• Rheumatic fever, a serious complication of strep throat that can affect the heart valves

Risk factors for heart murmurs

Some factors that can increase the risk of heart murmurs include:

• A family history of heart problems linked to murmurs
• Uncontrolled diabetes in the mother during pregnancy
• German measles (rubella) in the mother during pregnancy
• Use of certain medications, alcohol, or illegal drugs by the mother during pregnancy
• Certain medical conditions, such as carcinoid syndrome, cardiomyopathy, endocarditis, hypereosinophilic syndrome, lupus, rheumatoid arthritis, pulmonary hypertension, a history of rheumatic fever, and hyperthyroidism

Prevention and treatment of heart murmurs

There is no known prevention for heart murmurs, but healthy lifestyle changes can improve heart health and prevent some conditions linked to murmurs in adults. Many childhood heart murmurs go away on their own as children grow. Treatment for heart murmurs depends on the cause and can include medication or surgery.

High blood pressure and hypertension: Alcohol consumption is linked to high blood pressure, which can increase the risk of heart attack and stroke

Alcohol consumption is linked to high blood pressure, which can increase the risk of heart attack and stroke. Excessive alcohol intake can lead to high blood pressure, heart failure, or stroke. The magnitude and direction of the effects of alcohol on blood pressure depend on the time after alcohol consumption. High-dose alcohol has a biphasic effect on blood pressure; it decreases blood pressure up to 12 hours after consumption and increases blood pressure after 13 hours. High-dose alcohol increases heart rate at all times up to 24 hours.

High blood cholesterol: Heavy drinking increases LDL (bad) cholesterol and decreases HDL (good) cholesterol, leading to a higher risk of heart disease

It is not advisable to drink beer if you have a heart murmur as it can worsen the condition. Heart murmurs are usually caused by problems with the heart's structure, and alcohol can further damage the heart.

Heavy drinking increases LDL (bad) cholesterol and decreases HDL (good) cholesterol, leading to a higher risk of heart disease. Alcohol intake affects cholesterol levels differently, depending on the level and frequency of consumption. Light to moderate alcohol intake can raise HDL levels, but heavy drinking increases total cholesterol, LDL, and triglycerides, which raises the chance of developing cardiovascular disease.

LDL cholesterol contributes to cholesterol buildup in the arteries, causing them to narrow. This buildup can lead to high blood pressure, heart failure, stroke, or heart disease. Additionally, heavy drinking can lead to heart muscle disease (cardiomyopathy), irregular heartbeat (arrhythmia), and congestive heart failure.

To maintain healthy cholesterol levels, it is recommended to keep total cholesterol below 200 mg/dL, LDL cholesterol below 130 mg/dL, and HDL cholesterol above 40 mg/dL for males and 50 mg/dL for females.

While light to moderate drinking may not negatively impact cholesterol levels, heavy drinking impairs heart health and increases the risk of heart disease and related death. Therefore, it is crucial to drink in moderation or abstain from alcohol to maintain optimal heart health.

Irregular heart rhythm/arrhythmia: Alcohol can disrupt the heart's natural pacemaker, leading to breathlessness and chest pains

Drinking alcohol can have adverse effects on individuals with heart murmurs. Heart murmurs are unusual sounds in the heartbeat, often indicating a problem. Alcohol can cause heart murmurs and lead to severe complications.

Alcohol and Irregular Heart Rhythm/Arrhythmia:

Alcohol can significantly impact the heart's natural rhythm, leading to a condition called arrhythmia. Arrhythmia is characterised by an irregular heartbeat, where the heart beats too slowly, too quickly, or with an uneven rhythm. This disruption can occur because alcohol can interfere with the heart's natural pacemaker, leading to electrical abnormalities in the heart.

Breathlessness and Chest Pains:

Breathlessness and chest pains are common symptoms associated with arrhythmia. When the heart's rhythm is disrupted, it can lead to a reduced pumping efficiency, affecting the body's oxygen supply. This reduction in oxygenated blood can result in breathlessness, as the body struggles to get enough oxygen. Additionally, the strain on the heart can cause chest pains, especially during physical activity.

Other Symptoms and Complications:

In addition to breathlessness and chest pains, arrhythmia caused by alcohol consumption can lead to a range of other symptoms, including:

• Heart palpitations
• Fatigue or weakness
• Lightheadedness or fainting
• Bulging neck veins
• Fluid buildup and swelling, especially in the lower extremities
• Loss of appetite and muscle mass
• Liver swelling or hardening

Alcohol-Induced Cardiomyopathy:

Prolonged and excessive alcohol consumption can lead to a condition called alcohol-induced cardiomyopathy, where the heart changes shape due to stretching and enlargement. This condition weakens the heart muscle, further disrupting the heart's rhythm and causing arrhythmia. Cardiomyopathy can lead to severe complications, including heart failure, stroke, and heart attack.

Holiday Heart Syndrome:

Even a single episode of binge drinking can lead to a condition called "holiday heart syndrome," where an irregular heartbeat, or atrial fibrillation, develops. This can increase the risk of stroke, heart attack, and heart failure.

Prevention and Management:

The best way to prevent alcohol-related heart issues is to abstain from alcohol or drink in moderation. Moderation typically means no more than one drink per day for women and one to two drinks per day for men. Additionally, seeking medical advice and support is crucial for managing alcohol consumption and related heart issues.
