Physiologic effects of stress dose corticosteroids in in-hospital cardiac arrest (CORTICA): A randomized clinical trial.

Aim: Postresuscitation hemodynamics are associated with hospital mortality/functional outcome. We sought to determine whether low-dose steroids started during and continued after cardiopulmonary resuscitation (CPR) affect postresuscitation hemodynamics and other physiological variables in vasopressor-requiring, in-hospital cardiac arrest.

Methods: We conducted a two-center, randomized, double-blind trial of patients with adrenaline (epinephrine)-requiring cardiac arrest.

Dimethylarginines in acute myocardial infarction: Association with lifestyle, sociodemographic, and somatometric factors.

Background: Recent findings associate asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) with the prognosis of acute myocardial infarction (AMI). The purpose of the current study was to associate patients' lifestyle, sociodemographic, and somatometric characteristics with the time course of ADMA and SDMA concentrations in the serum of AMI patients.

Patients And Methods: In the serum of 66 AMI patients, ADMA, SDMA, troponin T, and C-reactive protein (CRP) were measured upon hospital admission (<24 h) and on the 3 day following.

Impact of β-thalassemia trait carrier state on inflammatory status in patients with newly diagnosed hypertension.

Background: B-thalassemia carrier state or thalassemia minor confers cardiovascular protection through favorable lipidemic and blood pressure profile. However, its impact on inflammatory status-a common denominator of the above conditions-has not been addressed.

Methods: We investigated a wide range of inflammatory markers [white blood cell (WBC) count, homocysteine, C-reactive protein (CRP), serum amyloid A (SAA), fibrinogen, plasminogen, fibronectin, plasminogen activator inhibitor-1 (PAI-1), and uric acid] in a large cohort of 15 805 newly diagnosed hypertensive patients (8299 men, 7506 women); 626 of them (4.

Pre-loading therapy with statins in patients with angina and acute coronary syndromes undergoing PCI.

Statins constitute the most powerful class of drugs for cardiovascular risk reduction associated to atherosclerosis. Their important pharmacological properties include reduction of serum lipid concentrations and non-lipid related, pleotropic effects such as anti-inflammatory action. Previous largescale randomized studies have demonstrated the beneficial effects of statin loading prior to elective percutaneous coronary intervention (PCI) for the reduction of periprocedural myocardial infarction and prevention of major adverse cardiac events at 30 days.

Celiac Artery Avulsion Secondary to Blunt Trauma: A Case Report.

Celiac artery (CA) injuries are very rare and are often associated with high mortality. These injuries are associated more often with penetrating trauma rather than blunt trauma injury. Our case highlights a blunt trauma injury of CA in a hemodynamically stable patient without any symptoms that was treated conservatively.

Association between anxiety and depression in patients with acute coronary syndromes due to financial crisis.

Background: The effect of anxiety and depression on patients with acute coronary syndromes (ACS) warrants investigation, especially during periods of economic crisis.

Aim: To investigate the relation between anxiety and depression in patients presenting with ACS due to financial crisis and to investigate whether these two entities could predict long-term cardiovascular mortality.

Methods And Results: Anxiety and depression symptoms were assessed in 350 patients (210 men) presenting with ACS, with 70 (20%) patients showing elevated scores (Hellenic Heart Failure Protocol).

Diagnosis and Treatment of Left-Sided Prosthetic Paravalvular Regurgitation.

Paravalvular leak (PVL) is a complication related to the surgical implantation of left-sided prosthetic valves. The prevalence of paravalvular regurgitation ranges between 5 and 20%. Left-sided prosthetic paravalvular regurgitation presents with a wide constellation of signs and symptoms ranging from asymptomatic murmur to heart failure, hemolysis and cardiac cachexia.

Transforming growth factor-β inhibition and endothelin receptor blockade in rats with monocrotaline-induced pulmonary hypertension.

Transforming growth factor-β (TGF-β) inhibition is an investigational therapy for pulmonary arterial hypertension with promising results in experimental studies. The present work compared this approach with endothelin-receptor blockade and evaluated the effects of combined administration. Pulmonary arterial hypertension was induced by single monocrotaline injection (60 mg/kg) in 75 Wistar rats and 15 rats served as controls.

Transforming growth factor-β inhibition attenuates pulmonary arterial hypertension in rats.

The role of transforming growth factor-β in the pathogenesis of pulmonary arterial hypertension is unclear. We examined the effects of T9429, an antibody against transforming growth factor-β receptors, on hemodynamic, histological and functional parameters in the rat model of monocrotaline-induced pulmonary hypertension. One week after monocrotaline injection (60 mg/kg) in 28 Wistar rats, T9429 (0.

Endothelin-B receptors and ventricular arrhythmogenesis in the rat model of acute myocardial infarction.

The arrhythmogenic effects of endothelin-1 (ET-1) are mediated via ETA-receptors, but the role of ETB-receptors is unclear. We examined the pathophysiologic role of ETB-receptors on ventricular tachyarrhythmias (VT/VF) during myocardial infarction (MI). MI was induced by coronary ligation in two animal groups, namely in wild-type (n = 63) and in ETB-receptor-deficient (n = 61) rats.
