Age, DCM etiology, congestive heart failure, and LV echocardiographic Z scores are risk factors for death in children [8]. Prenatal screening and genetic counseling are able to help to provide a pre-symptomatic diagnosis for neonatal DCM. At present, there are studies on bone marrow transplantation and enzyme replacement therapy for IEM. Accurate classification of DCM for newborns is conducive to early treatment and changes the prevalence and natural course of DCM [69]. Acute or chronic right heart failure leads to elevation of liver enzymes most likely due to liver congestion, whereas cirrhosis due to cardiac disease is infrequent.
However, modulatory influences related to drinking patterns, genetic susceptibility, nutritional factors, ethnicity, and gender also many play a role (Piano and Phillips 2014) (figure 4). For classic ARVC mutations, a US and Dutch study elaborates on genotype-phenotypic associations in 577 patients. Eighty percent of patients carry a single mutation of PKP2, 4% of patients carry a complex mutation, and patients with a single mutation have a better prognosis.

In all three ethanol groups, compared to control groups there was a significant increase in heart weight-to-body weight ratios. In terms of cardiac function and structure, significant decreases in fractional shortening and ejection fraction were found in all ethanol groups, but no other changes were found in other echocardiography-derived parameters between the alcohol and control https://ecosoberhouse.com/ groups. Intra-myocardial lipid accumulation, which was direct contact with the mitochondria, was found in all ethanol-fed groups and was significantly correlated with increased myocardial triglyceride content. LCFA uptake was evaluated in isolated cardiomyocytes obtained from ethanol-fed rats and was increased in a dose-dependent manner (i.e., greatest in 18% ethanol group) (33).
Renaud and de Lorgeril [93] suggested that the inhibition of platelet reactivity by wine may be one explanation for protection from CAD in France. More than 1.8 million individuals in Germany with a total population of 81 million inhabitants are alcohol dependant. In a world-wide setting, alcoholic cardiomyopathy 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].
Cutting-Edge Structural Interventions Hypertrophic Septum: Ablation, Transcatheter Myotomy or Medical Therapy?
To treat the alcohol problem, a combined approach comprising pharmacologic and psychosocial therapy involving self-help groups or Alcoholics Anonymous is essential. Biomarkers of heart failure such as NT-proBNP and of myocardial necrosis such as the troponins and CKMB indicate heart failure or myocytolysis. In his 1972 review article, Bridgen was the first to introduce the term alcoholic cardiomyopathy [27]. Furthermore, there are conflicting data among studies regarding the prognosis of the condition, with some showing overall mortality near 60% and others showing a mortality rate of only 19% (Table (Table11). Additionally, the accepted ACM definition does not take into account a patient’s sex or body mass index (BMI). As women typically have a lower BMI than men, a similar amount of alcohol would reach a woman’s heart after consuming smaller quantities of alcohol.
The term alcoholic cardiomyopathy (ACM) has been widely used to describe a specific heart muscle disease found in individuals with a history of long-term heavy alcohol (ethanol) consumption. Data from human and animal studies have revealed that within the myocardium, a number of adverse histological, cellular, and structural changes occur in response to and over the course of long-term heavy alcohol consumption. The most important unresolved question, however, relates to the primary injury/mechanism by which ethanol stimulates or initiates this array of adverse changes within the myocardium. Several inter-related mechanisms may include oxidative stress, apoptotic cell death, impaired mitochondrial bioenergetics/stress, derangements in fatty acid metabolism and transport, and accelerated protein catabolism. In this review, we discuss these mechanisms, as well as the potential importance of drinking patterns, genetic susceptibility, nutritional factors, ethnicity, and sex in the development of ACM. Prognosis in individuals with low or moderate consumption up to one or two drinks per day in men and one drink in women is not different from people who do not drink at all.
Biomarkers for the diagnosis and management of heart failure
In 2008, the European Society of Cardiology (ESC) also proposed a new classification of cardiomyopathy [2]. Compared with the AHA classification, the ESC classification believes that gene detection is not a priority factor for clinical diagnosis and treatment of cardiomyopathy, and classification based on structure and dysfunction is more consistent with practice. In addition, the differentiation of primary and secondary diseases by affected organs may sometimes be inconsistent with the location of major pathological changes or manifestations of cardiomyopathy. Therefore, ESC classification discards the concept of primary and secondary cardiomyopathy, but classifies them based on different morphological and functional phenotypes, and further divides each classification into familial/genetic and non-familial/genetic subgroups.
- To solve this problem, in 2013, World Heart Federation (WHF) proposed a diversified MOGE (S) classification scheme based on AHA and ESC [13].
- Although beyond the scope of this review, it is possible that certain dietary components and/or deficiencies may increase either the susceptibly or progression of ethanol-induced myocardial changes.
- Myocarditis is the acquired cause of more than 46% of non-idiopathic DCM [68].
- One common risk factor for CV disease is the composition of the lipids found in the blood, and the effects of alcohol consumption on lipid profiles have been extensively studied.
