Glutathione Infusion Before and 3 Days After Primary Angioplasty Blunts Ongoing NOX2-Mediated Inflammatory Response.

Background Glutathione is a water-soluble tripeptide with a potent oxidant scavenging activity. We hypothesized that glutathione administration immediately before and after primary angioplasty (primary percutaneous coronary intervention) could be effective in modulating immune cell activation, thereby preventing infarct expansion. Methods and Results One hundred consecutive patients with ST-segment-elevation myocardial infarction, scheduled to undergo primary percutaneous coronary intervention were randomly assigned before the intervention to receive an infusion of glutathione (2500 mg/25 mL over 10 minutes), followed by drug administration at the same doses at 24, 48, and 72 hours elapsing time or placebo.

Acute atrial ischemia associates with early but not late new-onset atrial fibrillation in STEMI patients treated with primary PCI: relationship with in-hospital outcomes.

Background: New-onset atrial fibrillation (NOAF), both early (EAF) or late (LAF), may complicate ST-segment elevation myocardial infarction (STEMI). The mechanisms underlying EAF or LAF are poorly described. We investigated atrial branch occlusion and EAF or LAF onset in STEMI patients undergoing primary percutaneous coronary intervention.

Hypothermia during Surgical Treatment of Type A Aortic Dissection: A 16 Years' Experience.

Acute aortic dissection (AAD) is among the most challenging cases for surgical treatment and requires procedural expertise for its safe conduct. Aortic surgery has undergone several changes over the last years, especially concerning cerebral protection. The brilliant results obtained with the aid of selective anterograde cerebral perfusion led to a progressive increase of circulatory arrest temperature, with the rise of safe time along with a reduction of the extracorporeal circulation time and hypothermia-related side effects.

Two cases of acute chest discomfort and the Central Italy earthquake.

We present the cases of two postmenopausal women presenting to our emergency department with acute chest discomfort soon after the Central Italy earthquake. Different diagnoses were made in the two patients. The role of the earthquake as a stressful event triggering diverse chest pain syndromes is discussed.

Ivabradine in Patients with ST-Elevation Myocardial Infarction Complicated by Cardiogenic Shock: A Preliminary Randomized Prospective Study.

Background And Objective: An elevated heart rate (HR) is an independent risk factor for mortality and morbidity in patients with acute heart failure (HF). The purpose of this study was to evaluate the impact of ivabradine, a selective HR-lowering agent, in patients with cardiogenic shock (CS) complicating ST-elevation acute myocardial infarction (AMI).

Methods: Patients with post-AMI CS were randomized to standard treatment (SDT, 28 patients) or to standard treatment plus ivabradine (I + SDT, 30 patients).

Percutaneous assist devices in acute myocardial infarction with cardiogenic shock: Review, meta-analysis.

Aim: To assess the impact of percutaneous cardiac support in cardiogenic shock (CS) complicating acute myocardial infarction (AMI), treated with percutaneous coronary intervention.

Methods: We selected all of the studies published from January 1(st), 1997 to May 15(st), 2015 that compared the following percutaneous mechanical support in patients with CS due to AMI undergoing myocardial revascularization: (1) intra-aortic balloon pump (IABP) vs Medical therapy; (2) percutaneous left ventricular assist devices (PLVADs) vs IABP; (3) complete extracorporeal life support with extracorporeal membrane oxygenation (ECMO) plus IABP vs IABP alone; and (4) ECMO plus IABP vs ECMO alone, in patients with AMI and CS undergoing myocardial revascularization. We evaluated the impact of the support devices on primary and secondary endpoints.

The outcome of intra-aortic balloon pump support in acute myocardial infarction complicated by cardiogenic shock according to the type of revascularization: a comprehensive meta-analysis.

Aims: Despite the recommendations of the current guidelines, scientific evidence continue to challenge the effectiveness of intra-aortic balloon pump (IABP) in acute myocardial infarction (AMI) complicated by cardiogenic shock. Moreover, 2 recent meta-analyses showed contrasting results. The aim of this study is to test the effect of IABP according to the type of therapeutic treatment of AMI: percutaneous coronary intervention (PCI), thrombolytic therapy (TT), or medical therapy without reperfusion.

Lack of intra-aortic balloon pump effectiveness in high-risk percutaneous coronary interventions without cardiogenic shock: a comprehensive meta-analysis of randomised trials and observational studies.

Background: Although controversial, using prophylactic intra-aortic balloon pump (IABP) in patients undergoing high-risk percutaneous coronary intervention (PCI) has been reported to be effective by numerous registry studies. However, conflicting findings were observed in observational studies (Obs.) and randomised controlled trials (RCTs).

Clopidogrel plus indobufen in acute coronary syndrome patients with hypersensitivity to aspirin undergoing percutaneous coronary intervention.

The prescription of aspirin (acetylsalicylic acid (ASA)) to patients with a history of hypersensitivity to this drug could prove harmful. The aim of the study was to assess the antiplatelet activity and safety of a combined antiplatelet treatment with indobufen and clopidogrel in acute coronary syndrome (ACS) patients with hypersensitivity to aspirin, undergoing coronary stenting. Forty-two consecutive ACS patients treated with stent implantation were randomly assigned to receive clopidogrel 75 mg daily (loading dose 300 mg) plus indobufen 100 mg twice a day (group A), or clopidogrel 75 mg daily, after 300 mg of loading dose (group B).

Ambulatory blood pressure monitoring in prehypertensive subjects.

Background: Although treatment of prehypertensives is feasible and effective, it is unclear how to define those who may benefit. We hypothesized that ambulatory blood pressure monitoring (ABPM) might be a tool for selecting prehypertensive subjects, classified according to the JNC 7, who later develop drug-treated hypertension.

Methods: Prehypertensives (n=107; 62 M, 45 F; age 50 ± 14 years) with or without cardiovascular risk factors were assessed for drug-treated hypertension development.

Contrast ultrasound imaging: the best method to detect type II endoleak during endovascular aneurysm repair follow-up.

Objectives: Type II endoleak is the most common complication after endovascular aneurysm repair and require close surveillance. Hence, the need to validate new techniques as alternative to helical CT-scan, the reference standard. The aim of this study is to evaluate the efficacy of Cadence Contrast Pulse Sequencing ultrasound technique with second generation contrast agents in detecting endoleaks, and to compare the results with data obtained from CTA.

Clinical results of two year dual antiplatelet therapy after primary percutaneous coronary intervention with paclitaxel-eluting stents: a single centre study.

Aims: The long-term outcome of extended dual antiplatelet therapy after percutaneous coronary intervention (PCI) is unexplored. The purpose of the study was to evaluate the 2 year safety and efficacy of continuous dual antiplatelet treatment in patients undergoing primary PCI with paclitaxel-eluting stent (PES) for acute ST segment elevation myocardial infarction (STEMI).

Methods And Results: A series of 145 consecutive patients with STEMI underwent primary PCI with PES.

Comparative application of multivariate models developed in Italy and Europe to predict early (28 days) and late (1 year) postoperative death after on- or off-pump coronary artery bypass grafting.

Objectives: The aim of this study was to compare the risk of death predictive performances of the OP-RISK, EuroSCORE, and Italian coronary artery bypass grafting (CABG) Outcome studies' functions when applied to a southern Italian cardiac surgery center (Sant'Anna hospital in Catanzaro [SAHCZ]), which contributed data to the Italian CABG Outcome study, and to see if this predictive index may be applied to on- and off-pump interventions.

Methods: The OP-RISK study data set was used to derive Weibull and logistic functions to predict early (28 days) and late (1 year) death rates following CABG based on ejection fraction, heart rate, age, and aortic cross-clamping time. Then the data of 385 CABG patients who underwent operations in 2003 in SAHCZ were collected with 1-year follow-up data, which also included data used to obtain EuroSCORE and Italian CABG Outcome study risk indices.

Myocarditis in hypertrophic cardiomyopathy patients presenting acute clinical deterioration.

Aim: We sought to determine whether myocarditis can be a major cause of acute electrical instability or clinical deterioration in HCM patients.

Methods And Results: A total of 119 HCM patients (69 M/50F, mean age 41 +/- 8), 42 with acute clinical deterioration and 77 clinically stable, underwent cardiac catheterization with left ventricular endomyocardial biopsy and gene analysis of major sarcomeric proteins. Endomyocardial tissue was processed for histology, immunohistochemistry, and polymerase chain reaction for the most common cardiotropic viruses.

Age-related variations of varicose veins anatomy.

Background: Primary varicose veins are commonly considered a progressive disease starting from the saphenous junctions and extending to tributaries in a retrograde fashion along the saphenous trunks. This theory has been criticized by studies indicating different patterns of development and progression of varicose veins. To contribute to the understanding of the pathogenesis of the disease, the anatomy of the venous bed was comparatively evaluated by duplex sonography in patients with varicose veins with a marked difference in age.

Slow coronary flow and stress myocardial perfusion imaging. Different patterns in acute patients.

Objective: We investigated myocardial perfusion in acute patients with slow coronary flow (SCF) at angiography. Whether impaired myocardial perfusion occurs in acute patients with SCF is unknown.

Methods: We enrolled 28 consecutive patients with SCF in the epicardial coronary arteries with no evidence of significant stenosis.

Enoximone very low-dose dobutamine stress echocardiography: a new test for detecting viability in severe myocardial dysfunction after acute myocardial infarction.

Relying on the synergistic action on contractility of enoximone and dobutamine when concomitantly infused, 25 patients with their first acute Q-wave anterior myocardial infarctions underwent conventional low-dose dobutamine echocardiography (LDE) and enoximone very-LDE to assess myocardial viability in severely dysfunctioning areas. Images were recorded at peak of pharmacodynamic effect of drugs and 4 months after revascularization. At peak-dose stage of LDE and enoximone very-LDE the regional infarct zone wall-motion score significantly decreased from the basal value of 25.
