Clinical treatment strategies for patients with myocardial ischemia typically include coronary artery recanalization to restore myocardial blood supply. However, myocardial reperfusion insult often induces oxidative stress and inflammation, which further leads to apoptosis and necrosis of myocardial cells. Increasing evidence suggests that microRNAs (miRNAs) participate in the pathological and physiological processes associated with myocardial ischemia reperfusion.
Qishen Granule (QSG) is a prevailing traditional Chinese medicine formula that displays impressive cardiovascular protection in clinical. However, underlying mechanisms by which QSG alleviates endoplasmic reticulum (ER) stress-induced apoptosis in myocardial ischemia still remain unknown.
Authors present is comprehensive clinical and instrumental evaluation of patients with HCM with myocardial ischemia. 104 patients (38.4% of men) with HCM were examined, mean age 58.2±14.7. The examination included risk factors assessment for CAD, ECG, Echo, stress ECG test, 24-hour ECG monitoring. In the presence of myocardial ischemia, CAG (n=66) and MSCT of the coronary arteries (CA) (n=4) were performed. All patients were split up on 2 groups: I - 70 HCM patients with myocardial ischemia, 67.3%, and II ...
Functional assessment to rule out myocardial ischemia using coronary computed tomography angiography (CCTA) is extremely important and data on the Brazilian population are still limited.
This study assessed changes in myocardial native T and T values after supine exercise stress in healthy subjects and in patients with suspected ischemia as potential imaging markers of ischemia.
Coronary heart disease (CHD) is a common heart disease and the leading cause of cardiovascular death. Apoptosis and autophagy are two forms of programmed cell deaths which participate in the pathogenesis, development and prognosis of CHD. They are activated by several different pathways respectively and can interact with each other through the Beclin 1-Bcl-2/Bcl-xL complex, mTOR, TRAIL, TNF-α, ER stress and nucleus p53 pathways. Excessive apoptosis can promote myocardial ischemia, ischemia/reperfusion (I/R...
The effects of acute mental stress on the mechanisms regulating cerebral blood flow remain unclear. The major novel findings of this study were that: 1) high mental stress and hypercapnia had an interactive effect on mean middle cerebral artery blood velocity; 2) high mental stress altered the regulation of cerebral blood flow; 3) the increased cerebrovascular hypercapnic reactivity was not driven by changes in mean arterial pressure alone; and 4) this increased perfusion with mental stress appeared not to ...
Traditionally, elevated troponin concentrations were synonymous with myocardial infarction. But with improvements in troponin assays, elevated concentrations without overt myocardial ischemia are now more common; this is referred to as myocardial injury. Physicians may be falsely reassured by the absence of myocardial ischemia; however, recent evidence suggests that myocardial injury is associated with even more detrimental outcomes. Accordingly, this article reviews the definition, epidemiology, differenti...
Cardiovascular disorders are known as one of the main health problems which are associated with mortality worldwide. Myocardial ischemia (MI) is improper blood supply to myocardium which leads from serious complications to life-threatening problems like AMI, atherosclerosis, hypertension, cardiac-hypertrophy as well as diabetic associated complications as diabetic atherosclerosis/cardiomyopathy/hypertension. Despite several efforts, the current therapeutic platforms are not related with significant results....
The endoplasmic reticulum (ER) is the site of production and folding of secreted, membrane bound and some organelle targeted proteins. Accumulation of misfolded or unfolded proteins in the ER makes cells undergo a stress response known as the unfolded protein response (UPR). UPR is initially protective. However, prolonged and severe ER stress can lead to the induction of apoptosis in stressed cells. Cardiac hypertrophy and myocardial ischemia accounts for substantial morbidity and mortality worldwide. Accum...
Ergometrine is recommended for use in the medical treatment of postpartum hemorrhage. Ergometrine can occasionally precipitate myocardial ischemia in the setting of significant anemia in women without preexisting cardiac risk factors, and it is important to recognize and treat myocardial ischemia in affected patients to prevent severe complications.
Pregnancy is a sensitive period of life where mental health is of utmost importance to the mother's and child's well-being peripartum and beyond. To better prevent and treat common mental health conditions such as depressive symptoms and perceived stress (defined in this study to encompass psychological and physiological (heart rate variability (HRV)) dimensions), it is crucial to examine and report differences in mental health outcomes among demographically diverse pregnant women. Therefore, the purpose of...
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.
Myocardial ischemia is one of the most common cardiovascular pathologies and can indicate many severe and life threatening diseases. Despite these risks, current electrocardiographic detection techniques for ischemia are mediocre at best, with reported sensitivity and specificity ranging from 50--70\% and 70--90\%, respectively. To improve this performance, we set out to develop an experimental preparation to induce, detect, and analyze bioelectric sources of myocardial ischemia and determine how these sour...
Myocardial ischemia/reperfusion (MI/R) injury has a great influence on the prognosis of patients with acute coronary occlusion. The underlying mechanisms of MI/R injury are complex. While the incidence of MI/R injury is increasing every year, the existing therapies are not satisfactory. Recently, small ubiquitin-related modifier (SUMO), which is a post-translational modification and involved in many cell processes, was found to play remarkable roles in MI/R injury. Several proteins that can be SUMOylated we...
Myocardial ischemic disease affects the prognosis in perioperative patients. Diabetes can aggravate myocardial injury. The purpose of this research is to investigate the effect of ferroptosis in the process of diabetes mellitus (DM) myocardial ischemia/reperfusion (I/R) injury (IRI). Endoplasmic reticulum stress (ERS) is investigated whether aggravates cardiomyocytes injury. Rat DM+I/R (DIR), cell high glucose (HG), hypoxia reoxygenation (H/R), and high-glucose H/R (HH/R) models were established. Ferroptosi...
High density lipoprotein (HDL) protects against myocardial infarction via mechanisms that remain unclear. STAT3 (signal transducer and activator of transcription 3) plays a key role in HDL-induced cardioprotection. In the heart, microRNAs (miRNAs) are involved in ischemia reperfusion injury. We therefore investigated whether the cardioprotective effect of HDL modulates miRNAs as a downstream target of STAT3 activation.
To investigate the effect and mechanism of long non-coding ribonucleic acid (lncRNA) PFL on myocardial ischemia/reperfusion (I/R) injury in rats, and to provide a reference for the prevention and treatment of myocardial infarction (MI) in clinic.
The burden of coronary artery disease has been assessed by various semi-quantitative angiographic scores, which are frequently different each other. A non-invasive and quantitative modality may substitute angiographic sores for prognostic implication and decision of revascularization strategy. We compared fractional myocardial mass (FMM) with angiographic scores for predicting myocardial ischemia.
To study the myocardial benefit effect and mechanism of paeoniflorin on myocardial ischemia reperfusion injury (MIRI) in rats.
In the prehospital triage of patients presenting with symptoms suggestive of acute myocardial ischemia, reliable myocardial ischemia detection in the electrocardiogram (ECG) is pivotal. Due to large interindividual variability and overlap between ischemic and nonischemic ECG-patterns, incorporation of a previous elective (reference) ECG may improve accuracy. The aim of the current study was to explore the potential value of serial ECG analysis using subtraction electrocardiography.
Emotional stress leads to the development of peripheral disorders and is recognized as a modifiable risk factor for psychiatric disorders, particularly depression and anxiety. However, not all individuals develop the negative consequences of emotional stress due to different stress coping strategies and resilience to stressful stimuli. In this review, we discuss individual differences in coping styles and the potential mechanisms that contribute to individual vulnerability to stress, such as parameters of t...
Hypercholesterolemia is a major risk factor for ischemic heart disease including acute myocardial infarction. However, long-term effects of hypercholesterolemia in a rodent myocardial ischemia-reperfusion injury model are unknown. Therefore, the effects of diet-induced hypercholesterolemia on cardiac function and remodeling were investigated up to eight weeks after myocardial ischemia-reperfusion (MI-R) injury which was induced in either normocholesterolemic (NC-MI) or hypercholesterolemic (HC-MI) APOE*3-Le...
Dexmedetomidine (DEX) is a selective α2-adrenoceptor agonist that has anti-inflammatory and cardioprotective effects in myocardial ischemia/reperfusion (I/R) injury. The present study aimed to investigate the underlying mechanism by which DEX protects against myocardial I/R.
