Preconditioning with levosimendan reduces postoperative low cardiac output in moderate-severe systolic dysfunction patients who will undergo elective coronary artery bypass graft surgery: a cost-effective strategy.

Abstract
Background Patients with moderate-severe systolic dysfunction undergoing coronary artery bypass graft have a higher incidence of postoperative low cardiac output. Preconditioning with levosimendan may be a useful strategy to prevent this complication. In this context, design cost-effective strategies like preconditioning with levosimendan may become necessary. Methods In a sequential assignment of patients with Left Ventricle Ejection Fraction less than 40%, two strategies were compared in terms of cost-effectiveness: standard care (n = 41) versus preconditioning with Levosimendan (n = 13). The adverse effects studied included: postoperative new-onset atrial fibrillation, low cardiac output, renal failure and prolonged mechanical ventilation. The costs were evaluated using deterministic and probabilistic sensitivity analysis, and Monte Carlo simulations were performed. Results Preconditioning with levosimendan in moderate to severe systolic dysfunction (Left Ventricle Ejection Fraction < 40%), was associated with a lower incidence of postoperative low cardiac output in elective coronary artery bypass graft surgery 2(15.4%) vs 25(61%) (P < 0.01) and lesser intensive care unit length of stay 2(1–4) vs 4(3–6) days (P = 0.03). Average cost on levosimendan group was 14,792€ while the average cost per patient without levosimendan was 17,007€. Patients with no complications represented 53.8% of the total in the levosimendan arm, as compared to 31.7% in the non-levosimendan arm. In all Montecarlo simulations for sensitivity analysis, use of levosimendan was less expensive and more effective. Conclusions Preconditioning with levosimendan, is a cost-effective strategy preventing postoperative low cardiac output in patients with moderate-severe left ventricular systolic dysfunction undergoing elective coronary artery bypass graft surgery.

Abstract
Perioperative myocardial ischemia and dysfunction re main prevalent after cardiac surgery despite the use of conventional measures to provide myocardial protec tion. Myocardial preconditioning is a powerful, endog enously regulated means of myocardial protection that may also have some clinical usage for patients undergo ing cardiac surgical procedures. The paradoxical con cept of using ischemia as a stimulus for myocardial protection has been studied extensively in animals and humans. The specific characteristics and constituents of preconditioning have been well identified. The mecha nism remains to be completely elucidated due to differ ences among species and experimental models. Some pharmacologic agents are capable of mimicking the classic mechanism of ischemic preconditioning. Pharma cologic and ischemic preconditioning may have signifi cant clinical use and therapeutic efficacy as a means of providing myocardial protection during cardiac surgery, especially in procedures that do not use cardioplegia and cardiopulmonary bypass, such as minimally inva sive coronary artery bypass grafting. This article re views the characteristics, mechanisms, potential clini cal applications, and therapeutic efficacy of myocardial preconditioning.

Abstract
Because of improved social and medical standards in the western world, the average age of the population continues to increase. This altering demographic profile has its impact on the surgical population, resulting in a dramatic increase in the number of patients with exten sive cardiovascular disease, presenting for either car diac or noncardiac surgery. As a result, the incidence of perioperative acute congestive heart failure (CHF) is a major clinical problem at the present time. For the pharmacologic management of acute CHF, the β-adreno ceptor agonists continue to be the mainstay of therapy, due to their short duration of action and hemodynamic controlability by continuous intravenous infusion. Mono therapy with the phosphodiesterase type III (PDE) inhibi tors appears to be the treatment of choice in selected patients with high systemic vascular resistance or re sidual β-adrenoceptor blockade. Combination therapy especially deserves attention, because this approach allows the enhancement of contractile force, possibly without the side effects associated with the administra tion of high concentrations of one agent alone. New developments including ultrashort-acting PDE inhibi tors, calcium-dependent calcium sensitizers, and cal cium promotors are anxiously awaited.

Abstract
OBJECTIVE Ischemic heart disease (IHD) is a leading cause of mortality with insufficient results of current therapies, most probably due to maintained endothelial dysfunction conditions. Alternatively, we propose a new treatment that promotes endothelial shear stress (ESS) enhancement using an intrapulmonary pulsatile catheter. METHODS Twelve piglets, divided in equal groups of 6: pulsatile (P) and non-pulsatile (NP), underwent permanent left anterior descending coronary artery ligation through sternotomy. After 1 h of ischemia and heparin injection (150 IU/kg): in P group, a pulsatile catheter was introduced into the pulmonary trunk and pulsated intermittently over 1 h, and irrespective of heart rate (110 bpm). In NP group, nitrates were given (7 ± 2 mg/kg/min) for 1 h. RESULTS In P group all 6 animals survived ischemia for 120 min, but in NP group only 2 animals survived. The 4 animals that died during the experiment in NP group survived for 93 ± 14 min. Hemodynamics and cardiac output (CO) were significantly improved in P group compared with NP group: CO was 0.92 ± 0.15 vs. 0.52 ± 0.08 in NP group (L/min; p < 0.05), respectively. Vascular resistances (dynes.s.cm(-5)/kg) were significantly (p < 0.05) lower in P group versus NP group: pulmonary resistance was 119 ± 13 vs. 400 ± 42 and systemic resistance was 319 ± 43 vs. 1857 ± 326, respectively. Myocardial apoptosis was significantly (p < 0.01) lower in P group (0.66 ± 0.07) vs. (4.18 ± 0.27) in NP group. Myocardial endothelial NO synthase mRNA expression was significantly (p < 0.01) greater in P group (0.90 ± 0.09) vs. (0.25 ± 0.04) in NP group. CONCLUSIONS Intrapulmonary pulsatile catheter could improve hemodynamics and myocardial contractility in acute myocardial ischemia. This represents a cost-effective method, suitable for emergency setting as a first priority, regardless of classical coronary reperfusion.

Potentially neuroprotective gene modulation in an in vitro model of mild traumatic brain injury. Mol Cell Biochem 2012; 375:185-98.

Abstract
In this study, we investigated the hypothesis that mild traumatic brain injury (mTBI) triggers a controlled gene program as an adaptive response finalized to neuroprotection, similar to that found in hibernators and in ischemic preconditioning. A stretch injury device was used to produce an equi-biaxial strain field in rat organotypic hippocampal slice cultures at a specified Lagrangian strain of 10 % and a constant strain rate of 20 s(-1). After 24 h from injury, propidium iodide staining, HPLC analysis of metabolites and microarray analysis of cDNA were performed to evaluate cell viability, cell energy state and gene expression, respectively. Compared to control cultures, 10 % stretch injured cultures showed no change in viability, but demonstrated a hypometabolic state (decreased ATP, ATP/ADP, and nicotinic coenzymes) and a peculiar pattern of gene modulation. The latter was characterized by downregulation of genes encoding for proteins of complexes I, III, and IV of the mitochondrial electron transport chain and of ATP synthase; downregulation of transcriptional and translational genes; downregulation and upregulation of genes controlling the synthesis of glutamate and GABA receptors, upregulation of calmodulin and calmodulin-binding proteins; proper modulation of genes encoding for proapoptotic and antiapoptotic proteins. These results support the hypothesis that, following mTBI, a hibernation-type response is activated in non-hibernating species. Unlike in hibernators and ischemic preconditioning, this adaptive gene programme, aimed at achieving maximal neuroprotection, is not triggered by decrease in oxygen availability. It seems rather activated to avoid increase in oxidative/nitrosative stress and apoptosis during a transient period of mitochondrial malfunctioning.

Abstract
INTRODUCTION Morbidity and mortality in elective valve surgery is still significant. The main cause of death in these patients is cardiogenic shock, of which the most frequent etiology is acute myocardial infarction (AMI) with Q wave in the ECG. However, there are patients with cardiogenic shock without Q wave in the ECG and with rises in CK-MB enzyme that makes us suspect non-Q wave AMI. OBJECTIVE To analyze the use of the determination of cardiac troponin-I, a more specific marker of AMI than CK-MB after cardiac surgery, to detect perioperative non-Q wave AMI, and to establish its clinical significance. METHODS A total of 147 patients without coronary artery disease scheduled for elective valve surgery were included. We used, based in anterior publications, ECG (presence or not of new Q wave) and cardiac troponin I to define perioperative AMI. Levels of cardiac troponin-I were analysed before surgery and 14 hours after. Non-Q wave AMI was diagnosed when troponin I was superior to 38.85 ng/ml and there was not a phatologic Q wave in ECG. RESULTS One hundred twenty-three (83.67%) of patients did not have AMI, 9 (6.12%) suffered perioperative AMI with Q wave, and 15 (10.27%) carried out criteria of non-Q wave perioperative AMI. Morbidity and mortality in this last group was similar to that in the group with Q wave AMI. Morbidity and mortality were minimum in patients without AMI. CONCLUSIONS This study suggest the possibility of in vivo identification of non-Q wave perioperative AMI, an entity with important morbidity and mortality in our series, with a simple determination of cardiac troponin I 14 hours after surgery.

Abstract
This article describes clinical situations in which stunning occurs and updates previous reviews on the topic. Stunning following angioplasty, angina and exercise-induced ischemia, infarction, and after cardiac surgery are described. In addition, newer concepts regarding stunning, including neurogenic stunned myocardium, are discussed. Left atrial stunning following cardioversion is a recently recognized phenomenon with important clinical implications, but differs from the original concept of post-ischemic stunning.

Abstract
OBJECTIVES A reversible contractile dysfunction without necrosis after transient myocardial ischemia has been termed stunning. The molecular mechanisms underlying this phenomenon are only now beginning to be unraveled. It is conceivable that the expression of early-response genes may play a crucial role in stunning. METHODS The expression of HSP-70, c-jun, and GRP-94 was investigated in a chronically instrumented dog model (n = 9). The left anterior descending coronary artery was occluded temporarily for 10 minutes after the animals had fully recovered from instrumentation. The wall thickening fraction was measured in the left anterior descending coronary artery and the nonischemic ramus circumflex of the left coronary artery-perfused region. When the wall thickening fraction of the left anterior descending coronary artery had recovered to 50% of preocclusion values, tissue samples were obtained from the areas perfused by the left anterior descending coronary artery and the nonischemic ramus circumflex of the left coronary artery. RESULTS The messenger RNA of HSP-70 was increased to 214% +/- 26% in the area perfused by the left anterior descending artery compared with that perfused by the nonischemic ramus circumflex of the left coronary artery. There was no difference in the messenger RNA of GRP-94. The HSP-70 content was elevated to 130% +/- 14% in the left anterior descending artery compared with the area perfused by the ramus circumflex of the left coronary artery, and the c-jun protein content was 70% +/- 25% higher in the ischemic area compared with the control area. CONCLUSIONS The induction of early-response genes observed here may indicate that they play an adaptive role in myocardial stunning, even in conscious mammals.

Abstract
The prognosis of patients with end-stage heart failure presenting with acute clinical deterioration is poor. Extracorporeal membrane oxygenation (ECMO), however, can provide univentricular and biventricular cardiac support which has led to the extended application of ECMO to infants and children. With improving results, indications and modalities of mechanical support have changed, and mechanical bridge to cardiac transplantation will offer extended survival for selected patients. The purpose of this article is to provide comprehensive data of pediatric cardiac support and to discuss the central role of echocardiography in the estimation of cardiac performance during mechanical support. As a conclusion, one can predict that the encouraging results of today will lead to further technological developments, which will create individual technical solutions of different clinical applications.

Abstract
OBJECTIVE A beneficial effect of thoracic epidural anesthesia (TEA) on recovery from myocardial stunning was previously shown in awake dogs. The aim of this study was to investigate the effects of TEA on recovery from myocardial stunning in sevoflurane-anesthetized dogs. DESIGN Randomized animal study. SETTING Animal laboratory of a university hospital. PARTICIPANTS Chronically instrumented mongrel dogs. INTERVENTIONS Six dogs were chronically instrumented for measurement of hemodynamics and myocardial wall thickening fraction (WTF). The following experiments were performed on separate days in a crossover fashion: (1) 10 minutes of ischemia of the left anterior descending (LAD) coronary artery during sevoflurane anesthesia without TEA and (2) 10 minutes of ischemia during sevoflurane anesthesia with TEA. MEASUREMENTS AND MAIN RESULTS WTF was measured awake (baseline) and at predetermined time points until complete recovery of myocardial function occurred. Induction of anesthesia led to a decrease of WTF compared with baseline. Induction of ischemia led to a further decrease of WTF to negative values, which returned to positive values within the first minute of reperfusion. There were no differences between the two experimental conditions at any of the time points measured. In awake dogs, TEA improved the recovery from myocardial stunning compared with the control experiment. There was no difference between conscious dogs with TEA or sevoflurane-anesthetized dogs with or without TEA. CONCLUSION TEA has no additional protective effect on the recovery of WTF during sevoflurane anesthesia.
