This eventually limits the heart’s ability to pump oxygen-rich blood around the body. Although the most common cause of heart failure is coronary artery disease, ischemic cardiomyopathy is unlikely in the absence of a clear history of prior ischemic events or angina and in the absence of Q waves on the ECG strip. In most patients, exercise or pharmacologic stress testing with echocardiographic or nuclear imaging is an appropriate alcoholic cardiomyopathy is especially dangerous because screening test for heart failure due to coronary artery disease. In patients with dilated cardiomyopathy, if additional questions remain after a history is obtained and noninvasive testing is performed, cardiac catheterization may be used to help exclude other etiologies of heart failure. As pointed out before, the current accepted definition of ACM probably underestimates the number of women affected by the disease.

• Individuals living with alcoholic cardiomyopathy face an unpredictable long-term outlook.
• The per capita alcohol consumption of 9.7 l pure ethanol and the early onset of regular or episodic intensive drinking among young people in Germany consequently leads to high alcohol-related morbidity and mortality [5].
• Studies have shown an increase in reactive oxygen species (ROS) level in myocytes following alcohol consumption and thus causes oxidation of lipids, proteins, and DNA leading to cardiac dysfunction.
• When compared to other types of cardiovascular disorders, alcoholic cardiomyopathy is not common.
• The source was identified to be the filter of choice for wine and beer, i.e., diatomaceous earth [36].

It is therefore possible that most of these studies may have also consistently omitted most alcohol abusers in whom alcohol had already caused significant ventricular dysfunction. More than 1.8 million individuals in Germany with a total population of 81 million inhabitants are alcohol dependant. In a world-wide setting, alcohol use disorders show similarities in developed countries, where alcohol is cheap and readily available [8]. The many complications of alcohol use and abuse are both mental and physical—in particular, gastrointestinal [9], neurological [10, 11], and cardiological [12, 13]. The relationship of alcohol with heart disease or dementia is complicated by the fact that moderate alcohol consumption was shown not only to be detrimental but to a certain degree also protective against cardiovascular disease [14] or to cognitive function in predementia.

Alcoholic cardiomyopathy: Cytotoxicity of alcohol on heart muscle

This refers to the finding in the last century that moderate alcohol consumption could be the reason for the relatively low cardiovascular disease incidence in wine-drinking regions [92]. Renaud and de Lorgeril [93] suggested that the inhibition of platelet reactivity by wine may be one explanation for protection from CAD in France. Ethanol, the main component of alcoholic beverages, has toxic effects on cardiac cells. Chronic alcohol consumption damages these cells in the heart muscle, interfering with its structure and function. “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. The pathologic and histologic findings of alcoholic cardiomyopathy (AC) are essentially indistinguishable from those of other forms of dilated cardiomyopathy (DC).

Alterations in protein physiology/content can also be due to accelerated protein degradation. In skeletal muscle, ubiquitin E3 ligases, such as atrogin-1 and muscle RING Finger 1 (MuRF1), accelerate protein breakdown and lead to muscle atrophy (67,68). Recently, Lang and Korzick (65) reported that 20 weeks of alcohol consumption in female Fischer 344 rats increased myocardial atrogin-1 and MuRF1 expression (e.g., messenger ribonucleic acid levels). In this same study, investigators found increased markers of autophagy, such as LC3B and autophagy-related gene 7 proteins and tumor necrosis factor α, along with a reduction in mTOR activity. Autophagy is a catabolic mechanism carried out by lysosomes and is important for the degradation of unnecessary or damaged intracellular proteins, therefore keeping the cell healthy. This mechanism is also important for cell and organism survival during stress and nutrient deprivation.

Alcoholic cardiomyopathy: Pathophysiologic insights

Commonly seen cellular structural alterations include changes in the mitochondrial reticulum, cluster formation of mitochondria and disappearance of inter-mitochondrial junctions. Though they aren’t causes of alcohol-induced cardiomyopathy, other lifestyle choices can make it worse. These include using recreational drugs (especially those that affect your heart, such as cocaine) and tobacco (which has major negative effects on your heart, lungs and circulatory system).

Markers for chronic alcohol consumption rely on liver enzymes such as gamma-glutamyltransferase (GGT) [119], glutamic oxalacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT). Elevations of the transaminases (GOT, GPT), especially a ratio of GOT/GPT higher than 2 might be indicative of alcoholic liver disease instead of liver disease from other etiologies [120, 121]. An excellent marker is carbohydrate deficient transferrin (CDT), which best detects chronic alcohol consumption alone [122, 123] or in combination with the other markers such as GGT [8, 124]. Markers such as ethyl sulphate, phosphatidyl ethanol, and fatty acid ethyl esters are not routinely done. For a comprehensive overview see Table 2 with combined data from [6, 8, 24, 28]. In 1819 the Irish physician Dr. Samuel Black, who had a special interest in angina pectoris described what is probably the first commentary pertinent to the ”French Paradox“ [91].

Mental & Emotional Effects

ACM represents one of the leading causes of non-ischemic dilated cardiomyopathy. The major risk factor for developing ACM is chronic alcohol use; however, there is no cutoff value for the amount of alcohol consumption that would lead to the development of ACM. This activity describes the pathophysiology of ACM, its causes, presentation and the role of the interprofessional https://ecosoberhouse.com/ team in its management.ACM is characterized by increased left ventricular mass, dilatation of the left ventricle, and heart failure (both systolic and diastolic). This activity examines when this condition should be considered on differential diagnosis. This activity highlights the role of the interprofessional team in caring for patients with this condition.

People who consume large quantities of alcohol regularly over an extended period are at significant risk for ACM. Chronic heavy drinking is typically defined as consuming more than 15 drinks per week for men and more than 8 drinks per week for women. Inadequate nutrition can contribute to heart muscle damage and worsen the progression of alcoholic cardiomyopathy. The primary treatment for ACM involves complete abstinence from alcohol or other drugs.
