The abuse of this drug has led to significant health problems worldwide. Like other amphetamine-type stimulants, chronic consumption of methamphetamine leads to direct toxic effects on the central nervous system, causing cognitive impairment, depressive behavior, and other severe neurological or psychiatric symptoms. Besides its neurotoxicity, the drug exhibits numerous deleterious effects on the cardiovascular system, including hypertension, accelerated atherosclerosis, vasospasm-induced acute coronary syndromes, sudden cardiac death, and dilated cardiomyopathy with congestive heart failure and left ventricular dysfunction. The excessive release of catecholamines upon methamphetamine exposure causes vasoconstriction and vasospasm, which ultimately lead to hypertension, tachycardia, endothelial dysfunction, and cardiotoxicity. While numerous studies have focused on transcription factors expressed in the brain that cause the neurotoxic effects of the drug, much less is known about transcription factors involved in the development of methamphetamine-induced heart failure. In this article, we provide an overview of the Janus kinase-signal transducer and activator of transcription 3 (JAK-STAT3) pathway involved in ischemia/reperfusion injury in the myocardium, which may be activated by the vasospasm-inducing action of the drug.

Furthermore, it is used as a disinfectant for medicinal purposes and as a cultural asset it is also part of religious rituals. However, it is also an intoxicant and an addictive substance. The deleterious side of alcohol is reflected in the fact that around 3 million people worldwide die every year as a direct or indirect result of alcohol consumption. For several decades, epidemiological studies suggested that drinking alcohol in moderate quantities was beneficial. This was referred to as the \"French paradox,\" which described differences in mortality between France and Finland mainly, but also other countries, that were found in epidemiological studies. The difference in the levels of alcohol consumption was found to explain the differences in mortality in view of the otherwise similar risk factors. When alcoholic drinks per day were plotted against all-cause mortality this led to a J-shaped curve. This finding represented a window of benefit for moderate alcohol consumption. However, the recent publication by Zhao et al. in 2023 revisited the relationship between the quantity of alcohol consumed and mortality risk and led to a paradigm change, which has influenced not only the recommendations of Canada's Guidance on Alcohol and Health but also the recommendations and guidelines of major health organizations: \"No alcohol is better than a little.\" The J‑shaped curve as an explanation of the French paradox became a linear relationship between the amount of alcohol consumption and the increasing mortality from tumors and cardiovascular diseases. The renewed review of several control groups in previous epidemiological studies revealed a recruitment error due to the inclusion of abstinent ex-drinkers. Taking this bias into account, the alcohol-friendly view of small amounts of alcohol being cardioprotective had to be revised. The combined misuse of alcohol and other risk factors for carcinogenesis and heart diseases still needs further attention. The misuse of both alcohol and cocaine led to the conclusion that when the two risky substances are consumed together, it is even more detrimental than the mere sum of the two.</p>","PeriodicalId":12863,"journal":{"name":"Herz","volume":" ","pages":"409-419"},"PeriodicalIF":1.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11602851/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142567754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is often misdiagnosed as other types of cardiac or digestive disorders, leading to unnecessary treatments and reduced quality of life. Here, we provide a thorough review of RS, covering its pathogenesis, etiology, diagnosis, treatment, and outcome. We found that a number of conditions, including gallstones, hiatal hernia, excessive gas, and gastroesophageal reflux syndrome, can cause RS. The symptoms of RS can include chest pain, palpitations, shortness of breath, nausea, vomiting, bloating, and abdominal pain. Clinical history, physical examination, electrocardiograms, and improvement in symptoms following gastrointestinal therapy can all be used to identify RS. We also propose a set of criteria, the IKMAIR criteria, to improve the diagnostic approach for this condition. Dietary changes, lifestyle adjustments, pharmaceutical therapies, and surgical procedures can all be used to control RS. Depending on the underlying etiology and the outcome of treatment, RS has a varying prognosis. We conclude that RS is a complicated and understudied disorder that needs more attention from researchers and patients as well as from medical professionals.
