Aims: We aimed to identify a novel biomarker involved in the early events leading to an acute coronary syndrome (ACS) and evaluate its role in diagnosis and risk stratification. Methods and results: Biomarker identification was based on gene expression profiling. In coronary thrombi of ACS patients, cysteine-rich angiogenic inducer 61 (Cyr61, CCN1) gene transcripts were highly up-regulated compared with peripheral mononuclear cells. In a murine ischaemia-reperfusion model (I/R), myocardial Cyr61 expression was markedly increased compared with the controls...

BACKGROUND: Early outcomes of patients in the PRAGUE-18 study did not find any significant differences between two potent P2Y12 inhibitors. OBJECTIVE: The one-year follow-up of the PRAGUE-18 study focused on (1) a comparison of efficacy and safety between prasugrel and ticagrelor, and (2) on the risk of major ischemic events related to an economically motivated post-discharge switch to clopidogrel. METHODS: A total of 1,230 patients with acute myocardial infarction (MI) treated with primary PCI were randomized to prasugrel or ticagrelor with an intended treatment duration of 12 months...

Cardiac contractile function is adenosine-5'-triphosphate (ATP)-intensive, and the myocardium's high demand for oxygen and energy substrates leaves it acutely vulnerable to interruptions in its blood supply. The myriad cardioprotective properties of the natural intermediary metabolite pyruvate make it a potentially powerful intervention against the complex injury cascade ignited by myocardial ischemia-reperfusion. A readily oxidized metabolic substrate, pyruvate augments myocardial free energy of ATP hydrolysis to a greater extent than the physiological fuels glucose, lactate and fatty acids, particularly when it is provided at supra-physiological plasma concentrations...

Necrotizing eosinophilic myocarditis is a rare but potentially fatal condition that requires prompt recognition and treatment. We describe a case of a young athlete presenting with chest pain and breathlessness, with evidence of rapidly deteriorating cardiac function. The condition was successfully treated with corticosteroids, with no evidence of residual myocardial damage. This is the first reported case to demonstrate the utility of cardiac magnetic resonance imaging for diagnosis and monitoring response to treatment...

AIMS: While abnormal resting LV GLS has been described in patients with chronic heart failure with preserved ejection fraction (HFpEF), its prognostic significance when measured during an acute heart failure hospitalization remains unclear. We assessed the association between left ventricular global longitudinal strain (LV GLS) and outcomes in patients hospitalized with acute HFpEF. METHODS AND RESULTS: We studied patients discharged alive for acute HFpEF from Duke University Medical Center between 2007 and 2010...

The practice of transferring patients between acute care hospitals is variable and largely nonstandardized. Although often-cited reasons for transfer include providing patients access to specialty services only available at the receiving institution, little is known about whether and when patients receive such specialty care during the transfer continuum. We performed a retrospective analysis using 2013 100% Master Beneficiary Summary and Inpatient claims files from Centers for Medicare and Medicaid Services...

REVIEW
Cian P McCarthy, James L Januzzi
Suppression of tumorigenicity 2 (ST2) is a member of the interleukin (IL)-1 receptor family, whose role was originally established in the context of inflammatory and autoimmune diseases. More recently, testing for ST2 has been used in the setting of cardiovascular disease. The soluble form of ST2 is a decoy receptor that inhibits beneficial cardioprotective effects of IL-33; such inhibition results in cardiac hypertrophy, myocardial fibrosis, and ventricular dysfunction. Measurement of soluble ST2 has utility for assessing heart failure severity and prognosis...

INTRODUCTION: The coexistence of diabetes among people with acute myocardial infarction (AMI) or acute ischemic stroke (AIS) is common. However, little is known about the extent of excess medical expenditures associated with having diabetes among AMI and AIS patients. METHODS: Data on 3,307 AMI patients and 2,460 AIS patients aged ≥18 years from the 2008 to 2014 Medical Expenditure Panel Survey were analyzed. Per capita annual medical expenditures associated with diabetes were separately estimated by healthcare components with generalized linear models and two-part models...

Kawasaki disease (KD) is an acute, self-limited vasculitis affecting young children. It can result in coronary artery abnormalities in a significant proportion of patients, especially if the diagnosis is missed or treatment gets delayed. Echocardiography is the imaging modality of choice for detection of coronary artery abnormalities and assessment of myocardial function. It is also useful for characterization and risk stratification of patients with KD. Echocardiography should be performed at the time of diagnosis and then again at 1-2 weeks and 4-6 weeks after treatment, for uncomplicated cases who do not have significant coronary artery involvement...

Acute traumatic spinal cord injury (tSCI) results in a lifetime of paralysis associated with a host of medical complications. The developing secondary complications of tSCI may result in further chronic neurodegenerative diseases. Sevoflurane preconditioning (SF-PreCon) has shown guaranteed protective effects in myocardial or cerebral ischemic/reperfusion injury. However, the role of SF-PreCon in tSCI still remains to be elucidated. Here, we found that SF-PreCon ameliorated the developing secondary complications through reducing the apoptosis rate and the secretion of inflammatory cytokines in injured spinal cord tissues, and therefore enhancing the recovery after tSCI...

AIMS: Acute coronary syndrome (ACS) guidelines have been changed, favouring more potent antiplatelet drugs. We aimed to evaluate the safety and efficacy of a ticagrelor- instead of a clopidogrel-based primary dual antiplatelet (DAPT) regimen in ACS patients treated with newer-generation drug-eluting stents (DES). METHODS AND RESULTS: CHANGE DAPT (clinicaltrials.gov: NCT03197298) assessed 2,062 consecutive real-world ACS patients, treated by percutaneous coronary intervention (PCI), the primary composite endpoint being net adverse clinical and cerebral events (NACCE: all-cause death, any myocardial infarction, stroke or major bleeding)...

Cardiac arrest (CA) is the most serious clinical emergency situation and cardiopulmonary-cerebral resuscitation (CPCR) performed on site with high quality is the optional therapy for its management. It has been reported that prolonging the resuscitation time after 30-minute failed conventional cardiopulmonary resuscitation (CPR) could improve the in-hospital survival rate of CA patients, and how to improve the out-hospital survival rate and survival quality of these patients is a research hot focus at present...
