The protective effects of hydrogen sulfide on the myocardial ischemia via regulating Bmal1.

To investigate the effect of hydrogen peroxide (HS) on myocardial clock gene Bmal1 in ischemic cardiomyocytes.

The cystathionine γ-lyase/hydrogen sulfide pathway mediates the trimetazidine-induced protection of H9c2 cells against hypoxia/reoxygenation-induced apoptosis and oxidative stress.

Trimetazidine is a piperazine-derived metabolic agent. It exerts cardioprotective effects against myocardial ischemia/reperfusion (I/R) injury. In addition, studies confirm that the cystathionine γ-lyase (CSE)/hydrogen sulfide (H2S) pathway serves a beneficent role in attenuating myocardial I/R injury. However, the underlying role of the CSE/H2S pathway in the trimetazidine-induced protection against myocardial I/R injury remains elusive. Therefore, this study investigated whether trimetazidine ameliorates...

Comparison of QT interval variability of coronary patients without myocardial infarction with that of patients with old myocardial infarction.

The significant association of myocardial ischemia with elevated QT interval variability (QTV) has been reported in myocardial infarction (MI) patients. However, the influence of the time course of MI on QTV has not been investigated systematically.

Prognostic value of ST2 in myocardial infarction.

Soluble Suppression of Tumorigenicity 2 (ST2) is a biomarker of myocardial fibrosis increasingly recognized as a predictor of morbidity and mortality in heart failure. Its role in the prognosis after a myocardial infarction has not been validated to date.

Application of High-Sensitivity Troponin in Suspected Myocardial Infarction.

Data regarding high-sensitivity troponin concentrations in patients presenting to the emergency department with symptoms suggestive of myocardial infarction may be useful in determining the probability of myocardial infarction and subsequent 30-day outcomes.

A case of repetitive myocardial infarction with unobstructed coronaries due to Churg-Strauss syndrome.

Myocardial infarction is most commonly caused by thrombosis occurring on a background of coronary atherosclerosis, resulting in reduced coronary flow. Less often, myocardial infarction can occur in the absence of coronary disease. The pathomechanism of myocardial infarction in such patients is heterogeneous and more challenging to diagnose and treat. European Society of Cardiology published a position paper on myocardial infarction in patients with non-obstructive coronary disease, with definitions and reco...

Elevated troponin without a myocardial infarction.

The interpretation of troponin elevation whitout a typical myocardial infarction symptomatology is a daily challenge in the acute care setting. Using current investigative techniques, doctors navigate between the five types of myocardial infarction established by the Fourth Universal Definition. However, due to the development of ultrasensitive troponin assays, the myocardial injury without ischemia, acute or chronic, is became a more common entity. The purpose of this article is to describe the situations ...

Sulfate assimilation regulates hydrogen sulfide production independent of lifespan and reactive oxygen species under methionine restriction condition in yeast.

Endogenously produced hydrogen sulfide was proposed to be an underlying mechanism of lifespan extension via methionine restriction. However, hydrogen sulfide regulation and its beneficial effects via methionine restriction remain elusive. Here, we identified the genes required to increase hydrogen sulfide production under methionine restriction condition using genome-wide high-throughput screening in yeast strains with single-gene deletions. Sulfate assimilation-related genes, such as , , , and , were found...

Acyl Selenyl Sulfides as the Precursors for Reactive Sulfur Species (Hydrogen Sulfide, Polysulfide, and Selenyl Sulfide).

Persulfides are receiving increased attention due to their links to hydrogen sulfide (HS) and hydrogen polysulfide (HS ). Their close analogues selenyl sulfides (RSeSHs), however, have limited literature precedent, and their reactivity and possible role in biology are largely unknown. Here, we devised an acyl selenyl sulfide template to study RSeSH chemistry. Their stability and reactivity toward amines/thiols were studied. These compounds can produce HS or HS under different conditions, suggesting that RSe...

MiR-101a attenuates myocardial cell apoptosis in rats with acute myocardial infarction via targeting TGF-β/JNK signaling pathway.

To investigate the effect of micro ribonucleic acid (miR)-101a on myocardial cell apoptosis in the rat model of acute myocardial infarction (AMI) and its regulatory mechanism.

Characterization of Dialkyldithiophosphates as Slow Hydrogen Sulfide Releasing Chemicals and Their Effect on the Growth of Maize.

Hydrogen sulfide is a key gasotransmitter for plants and has been shown to greatly increase their growth and survival to environmental stressors. Current methods to use chemicals, such as GYY-4137, that slowly release hydrogen sulfide result in the release of chemicals not found in the environment and may lack chemical structures that can be readily tuned to affect their release of hydrogen sulfide. In this article we describe the synthesis and slow release of hydrogen sulfide from dialkyldithiophosphates w...

Risk Factors and Outcomes of Very Young Adults Who Experience Myocardial Infarction: The Partners YOUNG-MI Registry.

Despite significant progress in primary prevention, the rate of myocardial infarction has not declined in young adults. We sought to compare the risk factor profiles and outcomes between individuals who experienced a first myocardial infarction at a very young (age ≤40) and young (40< age ≤50) age.

Obesity is associated with worse long-term outcomes in hypertrophic cardiomyopathy patients with acute myocardial infarction.

Hypertrophic cardiomyopathy is associated with poor prognosis. In our previous study, it has been reported that patients with acute myocardial infarction and hypertrophic cardiomyopathy exhibited worse long-term outcomes than those with acute myocardial infarction without hypertrophic cardiomyopathy and those with hypertrophic cardiomyopathy without acute myocardial infarction. In this article, we aimed to assess the impact of body mass index on the long-term outcomes of hypertrophic cardiomyopathy patients...

The effect of education and telephone follow-up intervention based on the Roy Adaptation Model after myocardial infarction: randomised controlled trial.

Patients' lifestyle changes after myocardial infarction reduce the risk of infarction. Nursing interventions are important for the initiation and maintenance of lifestyle adaptation.

Targeting Protein Tyrosine Phosphatase PTP-PEST for Therapeutic Intervention in Acute Myocardial Infarction.

The myocardial ischemia/reperfusion (I/R) injury is almost inevitable since reperfusion is the only established treatment for acute myocardial infarction (AMI). To date there is no effective strategy available for reducing the I/R injury. Our aim was to elucidate the mechanisms underlying myocardial I/R injury and to develop a new strategy for attenuating the damage it causes.

Diagnosis of myocardial infarction at autopsy: AECVP reappraisal in the light of the current clinical classification.

Ischemic heart disease is one of the leading causes of morbidity and death worldwide. Consequently, myocardial infarctions are often encountered in clinical and forensic autopsies, and diagnosis can be challenging, especially in the absence of an acute coronary occlusion. Precise histopathological identification and timing of myocardial infarction in humans often remains uncertain while it can be of crucial importance, especially in a forensic setting when third person involvement or medical responsibilitie...

Circadian onset and prognosis of myocardial infarction with non-obstructive coronary arteries (MINOCA).

Many acute cardiovascular events such as myocardial infarction (MI) follow circadian rhythms. Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a newly noticed entity with limited data on onset pattern and its impact on prognosis.

Pneumococcal Pneumonia Resembling Acute Myocardial Infarction in an Adolescent Male.

Myocarditis is commonly associated with viruses. However, we present a novel case of a teenager with pneumococcal pneumonia and bacteremia complicated by myocarditis and rhabdomyolysis, presenting with features of acute ST-elevation myocardial infarction and cardiogenic shock. Physicians should be aware that Streptococcus pneumoniae infection, like Group A Streptococcus, can mimic acute myocardial infarction in young males without cardiovascular risk factors.

High serum CRP influences myocardial miRNA profiles in ischemia-reperfusion injury of rat heart.

Prognosis of myocardial infarction tends to be worse when serum C-reactive protein (CRP) level is high. miRNAs are also known to be involved in different pathogeneses of heart diseases such as myocardial infarction. However, how CRP is involved in myocardial infarction has not been fully elucidated. We hypothesized that serum CRP changes the miRNA profile during ischemia-reperfusion injury (IRI) of the myocardium. To confirm this hypothesis, we performed global miRNA expression profiling of myocardium using...
