BACKGROUND AND AIMS: Therapeutic angiogenesis is a pivotal strategy for ischemic heart disease. The aim of the present study was to determine the effect and molecular mechanism of Shexiang Baoxin pills, a widely-used traditional Chinese medicine for ischemic heart disease, on angiogenesis in a rat model of myocardial infarction (MI). METHODS: We used the occlusion of left anterior descending coronary artery of Sprague-Dawley rats as a model of MI. The MI rats were treated with distilled water, Shexiang Baoxin pills, or Shexiang Baoxin pills + HET0016 (a selective blocker of the biosynthesis of 20-hydroxyeicosatetraenoic acid (20-HETE) at 10 mg/kg/day), respectively...

PURPOSE OF REVIEW: This review will highlight the recent advancements in acute ischemic stroke diagnosis and treatment, with special attention to new features and recommendations of stroke care in the neurocritical care unit. RECENT FINDINGS: New studies suggest that pre-hospital treatment of stroke with mobile stroke units and telestroke technology may lead to earlier stroke therapy with intravenous tissue plasminogen activator (tPA), and recent studies show tPA can be given in previously contraindicated situations...

BACKGROUND: Feeding jejunostomy has increasingly become a standard adjunctive procedure during major esophago-gastric resections. They provide nutritional support during the post-operative period as required. However, significant early complications have been reported, most notably small bowel necrosis. Literature reports have been restricted to case reports or series. This study aims to determine the frequency of this complication in a cohort of patients undergoing esophago-gastric resection, and identify any difference in the risk of this complication between patients undergoing esophagectomy and gastrectomy...

BACKGROUND: A substantial body of evidence demonstrates that myocardial revascularisation using bilateral internal mammary arteries (BIMA) improves long-term survival compared with single/left internal mammary artery (LIMA) grafting. To date, limited analyses have been made regarding other short-term and long-term outcomes in BIMA strategy. OBJECTIVES: The primary aim of the present review is to update the difference in long-term survival between BIMA and LIMA grafting and to thoroughly investigate other secondary short-term and long-term clinical outcomes between these two grafting procedures...

BACKGROUND: China has gaps in the quality of care provided to patients with ST-elevation myocardial infarction, but little is known about how quality varies between hospitals. METHODS AND RESULTS: Using nationally representative data from the China PEACE-Retrospective AMI Study, we characterized the quality of care for ST-elevation myocardial infarction at the hospital level and examined variation between hospitals. Two summary measures were used to describe the overall quality of care at each hospital and to characterize variations in quality between hospitals in 2001, 2006, and 2011...

A 39-year-old man with a history of sickle cell disease (SCD) presented with left leg weakness. He had a normal CT head and CT angiogram, but MRI head showed multiple acute bilateral cortical infarcts including in the right precentral gyrus. The MRI findings were more in keeping with an embolic source rather than stroke related to SCD, although it could not be ruled out. He also had an echocardiogram which revealed a patent foramen ovale. He was treated with antiplatelet therapy and also had red blood cell exchange transfusion...

Females show a varying degree of ischemic sensitivity throughout their lifespan, which is not fully explained by hormonal or genetic factors. Epidemiological data suggest that sex-specific life experiences such as pregnancy increase stroke risk. This work evaluated the role of parity on stroke outcome. Age-matched virgin (i.e., nulliparous) and multiparous mice were subjected to 60 min of reversible middle cerebral artery occlusion and evaluated for infarct volume, behavioral recovery, and inflammation. Using an established mating paradigm, fetal microchimeric cells present in maternal mice were also tracked after parturition and stroke...

Myocardial infarction is the global leading cause of mortality (Go AS et al. 2014). Coronary artery occlusion is its main etiology and it is commonly treated by Coronary Artery Bypass Graft (CABG) surgery (Wilson CT 2007). The long-term outcome remains unsatisfactory (Benedetto U 2016). The vein faces the phenomenon of restenosis during the post-surgery, which consists of re-occlusion of the lumen and usually requires secondary intervention even within one year after the initial surgery (Harskamp RE 2013). We propose an extensive study of the restenosis phenomenon by implementing two mathematical models previously developed: a heuristic Dynamical System (DS) (Garbey M and Berceli SA 2013), and a stochastic Agent Based Model (ABM) (Garbey M et al...

BACKGROUND: Although there are sex differences in management and outcome of acute coronary syndromes (ACS), sex is not a component of Global Registry of Acute Coronary Events (GRACE) risk score (RS) for in-hospital mortality prediction. We sought to determine the prognostic utility of GRACE RS in men and women, and whether its predictive accuracy would be augmented through sex-based modification of its components. METHODS: Canadian men and women enrolled in GRACE and Canadian Registry of Acute Coronary Events were stratified as ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation ACS (NSTE-ACS)...

Stroke-like migraine attacks after radiation therapy (SMART) syndrome manifests as prolonged episodes of cortical dysfunction, years after cranial irradiation. We present two cases demonstrating reversible hemispheric hypoperfusion. Case 1 presented with left hemispheric symptoms following previous similar episodes. CT perfusion (CTP) demonstrated reversible hemispheric hypoperfusion; subsequent investigations were consistent with SMART syndrome. Case 2 presented following the third episode of a hemispheric syndrome with near-identical CTP abnormalities...

Low androgen levels are associated with an increased risk of coronary artery disease (CAD), thrombosis and myocardial infarction (MI), suggesting that androgen has a protective role. However, little is known about the underlying molecular mechanism. Our genome-wide association study identified the ADTRP gene encoding the androgen-dependent TFPI regulating protein as a susceptibility gene for CAD and MI. The expression level of ADTRP was regulated by androgen, but the molecular mechanism is unknown. In this study, we identified the molecular mechanism by which androgen regulates ADTRP expression and tested the hypothesis that androgen plays a protective role in cardiovascular disease by activating ADTRP expression...

Melatonin, an endogenously produced hormone, might potentially limit the ischemia reperfusion injury and improve the efficacy of mechanical reperfusion with primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI). This study was aimed to evaluate whether the treatment effect of melatonin therapy in patients with STEMI is influenced by the time to administration. We performed a post hoc analysis of the Melatonin Adjunct in the Acute Myocardial Infarction Treated With Angioplasty trial (NCT00640094), which randomized STEMI patients to melatonin (intravenous and intracoronary bolus) or placebo during pPCI...

The mechanisms behind the increased mortality in patients with acute myocardial infarction and co-existing severe mental illness (SMI) compared with non-SMI patients remain unclear. We studied 12,102 patients with ST-elevation myocardial infarction treated with primary percutaneous coronary intervention, of whom 457 had SMI. The primary outcome was major adverse cardiac events (death, myocardial infarction, target vessel revascularization) at 30 days, 1 year, 2 years, and maximum follow-up. Patients with SMI were younger, more often women, had higher prevalence of active smoking and diabetes, and had a longer duration of symptoms than patients without SMI...

Transcatheter edge-to-edge mitral valve repair (TMVr) with MitraClip has proved to be safe and effective for high-risk surgical patients with severe symptomatic degenerative mitral regurgitation. There is paucity of data regarding its use in functional mitral regurgitation (FMR). The objective of this study was to evaluate the use of MitraClip in patients with symptomatic moderate or severe FMR and a high surgical risk. Medical libraries were systematically searched for studies assessing the use of MitraClip for patients with symptomatic moderate or severe FMR and a high surgical risk...
