BACKGROUND: Circulating miRNAs are potential biomarkers of the pathogenesis of certain diseases and in monitoring therapeutic responses. We hypothesized that serum miR-29 can determine risk of acute cardiac allograft rejection. METHODS: Peripheral vein blood was collected from 50 healthy volunteers and 506 patients during post-transplant surveillance. Serum cardiac troponin I (cTnI) and miR-29 was detected by ELISA and qRT-PCR assay respectively. Rejection risk was defined as International Society of Heart and Lung Transplant score from leukocyte infiltration of an endomyocardial biopsy...

Background The aim of the study was to assess the value of post-operative cardiac troponin T-levels, measured with a new highly sensitive assay (hs-cTnT), as a suitable parameter to predict patients' outcome after cardiac surgery. With the introduction of the new hs-cTnT assay the correlation between measured levels and the post-operative patient's outcome remains to be evaluated. Methods Patients undergoing coronary artery bypass grafting (n = 213) were included. Perioperative measurements of hs-cTnT and CK-MB were correlated to parameters of clinical outcome and further explored...

BACKGROUND: The successful treatment of military combat casualties with penetrating injuries is significantly dependent on the time needed to get the patient to an adequate treatment facility. Profound hypothermia-induced suspended animation for delayed resuscitation (SADR) is a novel approach for inducing cardiac arrest and buying additional time for such injuries. However, the time used to safely administer circulatory arrest (CA) is controversial. The goal of this study was to evaluate the safety of hypothermia-induced SADR over 90 and 120 min time intervals...

BACKGROUND: Matrix metalloproteinase 9 (MMP9) has recently emerged as a risk predictor in patients with cardiovascular diseases. However, little is known about the significance of increased plasma MMP9 in patients with perioperative myocardial injury. We aimed to investigate the role of MMP9 in the occurrence of myocardial injury during off-pump coronary artery bypass grafting (OPCAB). METHODS: A total of 34 consecutive patients with coronary artery diseases (CAD) were recruited in this prospective, observational study...

PURPOSE: Pre and post-operative administration of sevoflurane in myocardial revascularization surgery provides enhanced cardioprotective effects exerted by pharmacologic pre- and post-conditioning, as compared to propofol. The identification of the enzymes involved in conditioning mechanisms is crucial to the understanding of the effects of sevoflurane in cardiac surgery patients. The impact of sevoflurane on another crucial target organ-the kidney-was also assessed. METHODS: Ninety patients undergoing off-pump myocardial revascularization surgery were allocated to receive either intra- and postoperative sevoflurane (SS), intraoperative sevoflurane and postoperative propofol (SP), or intra- and postoperative propofol (PP))...

An elevation in plasma cardiac troponins is an indicator of increased perioperative risk in orthopaedic and vascular surgery, however, data on liver transplantation (LTx) are scarce. The aim of the study was to evaluate the prevalence of cardiac troponin I (cTnI) elevation in the perioperative period of LTx, and its potential relationship with 1-year mortality. MATERIAL AND METHODS: Analysis included 79 patients with liver cirrhosis. During LTx all patients underwent hemodynamic measurements...

Aims: Remote ischaemic preconditioning (RIPC) by inducing brief ischaemia in distant tissues protects the heart against myocardial ischaemia-reperfusion injury (IRI) in children undergoing open-heart surgery, although its effectiveness in adults with comorbidities is controversial. The effectiveness and mechanism of RIPC with respect to myocardial IRI in children with tetralogy of Fallot (ToF), a severe cyanotic congenital cardiac disease, undergoing open heart surgery are unclear. We hypothesized that RIPC can confer cardioprotection in children undergoing ToF repair surgery...

BACKGROUND: Myocardial damage is an independent predictor of adverse outcome following cardiac surgery and myocardial protection is one of the key factors to achieve successful outcomes. Cardioplegia with Custodiol is currently the most used cardioplegia during minimally invasive cardiac surgery (MICS). Different randomized controlled trials compared blood and Custodiol cardioplegia in the context of traditional cardiac surgery. No data are available for MICS. AIM: The aim of this study was to compare the efficacy of cold blood versus Custodiol cardioplegia during MICS...

OBJECTIVES: Shorter reperfusion times in ST-elevation myocardial infarction (STEMI) are associated with improved survival. Prehospital strategies have been developed to minimize door-to-balloon (DTB) time, but few strategies within the catheterization laboratory itself have been evaluated. Incomplete angiography (IA) prior to percutaneous coronary intervention (PCI) is undertaken in clinical practice as a means to further reduce DTB time. We sought to determine whether or not those with STEMI who underwent IA prior to PCI had different preprocedural characteristics or post-PCI outcomes...

INTRODUCTION: Nicorandil, a vasodilatory drug used to treat angina, was reported to protect against myocardial ischemia-reperfusion injury in various animal models. However, its cardioprotective action following cardiac arrest is unknown. We examined the cardioprotective effects of nicorandil in a porcine model of cardiac arrest and resuscitation. METHODS: Ventricular fibrillation was induced electrically for 4min in anesthetized domestic swine, followed by cardiopulmonary resuscitation...

AIM: Improved prediction of early post-discharge death or rehospitalization after admission for acute heart failure is a major unmet need. We evaluated the value of biomarkers to predict either low or high risk for early post-discharge events. METHODS AND RESULTS: A total of 1653 patients enrolled in the PROTECT trial who were discharged alive and with available blood samples were included. Forty-seven biomarkers were serially evaluated in these patients. Measurement closest to discharge was used to evaluate the predictive value of biomarkers for low and high post-discharge risk...

BACKGROUND: Despite advances in perioperative care, the rate of cardiac events in vascular patients remains high. We have previously shown that infections in trauma patients are associated with higher rates of subsequent cardiac complications, likely due to the additive effect of a second hit of an infection following the trauma. The aim of this study was to investigate whether there is an association between postoperative infections and subsequent cardiac events in vascular patients...

BACKGROUND: The value of cardiac troponin as a risk assessment tool for cardiac disease in the setting of end-stage renal diseases (ESRD) is not equivalent to its value in those with normal renal function. This consideration had not been studied in settings of acute kidney injury (AKI). We aim to explore the diagnostic value of high sensitive troponin T (hsTnT) in the settings of cardiac surgery-induced AKI. METHODS: Single center observational retrospective study...

Primary graft dysfunction after heart transplantation (HTx) has a very high mortality rate, especially if the left ventricle (PGD-LV) is involved. Early diagnosis is important to select the appropriate therapy to improve prognosis. The value of high-sensitivity troponin T (HS-TNT) measurement obtained at patient arrival at the intensive care unit was analyzed in 71 HTx patients. Mild or moderate PGD-LV was defined by hemodynamic compromise with one of the following criteria: left ventricular ejection fraction <40%, hemodynamic compromise with right atrial pressure >15 mm Hg, pulmonary capillary wedge pressure >20 mm Hg, cardiac index <2...

OBJECTIVE: Coronary heart disease (CHD) is a frequent medical condition in developed countries and is one of the most serious diseases threatening patients' lives. Perioperative myocardial infarction is the major cause of perioperative cardiac death and cardiac arrest, but is difficult to be precisely identified by observing clinical symptoms or assessing cardiac enzyme levels or by ECG examination. Therefore, assessment of patient prognosis requires reliable predictors. In this regard, we tested the prognostic value of serum troponin I (TnI) concentrations...

Prior studies have suggested that elevated serum Troponin-I (TnI) levels immediately after non-cardiac surgical procedures (8-40%) represent subclinical cardiac stress which independently predicts increased 30-day mortality. Routine post-operative TnI monitoring has therefore been suggested as a standard of care. However, no prior studies have focussed on elective degenerative spine surgery, whilst few have measured pre-op TnI. Further, prolonged prone positioning could represent an additional, independent, cardiac stress...
