The Use of Pressure Recording Analytical Method in Patients Undergoing Endovascular Repair for Abdominal Aortic Aneurysm: The Impact on Clinical Decisions for the Appropriate Postoperative Setting and Cost-effective Analysis.

Objective: To analyze the use of the Pressure Recording Analytical Method (PRAM), an hemodynamic monitoring system, in evaluating intraoperative and postoperative hemodynamic instability in patients undergoing endovascular repair for abdominal aortic aneurysm, and to evaluate if the decision to refer patients to a ordinary ward or to a Cardiac Step-Down Unit (CSDU) after the intervention on the basis of intraoperative hemodynamic monitoring could be more cost-effective.

Materials And Methods: After preoperative clinical evaluation, 44 patients were divided in this non-randomised study into two groups according to their postoperative destination: Group 1-ward (N=22) and Group 2-CSDU (N=22). All patients underwent monitoring with PRAM during the intervention and in the 24 postoperative hours, measuring several indices of myocardial contractility and other hemodynamic variables.

Transient stress-related hyperviscosity and endothelial dysfunction in Takotsubo syndrome: a time course study.

Takotsubo syndrome (TTS) is an acute and usually reversible heart failure syndrome, frequently associated with emotional or physical stress. Its pathophysiology remains largely unclear, although several mechanisms related to catecholaminergic storm have been proposed. In this study we analyzed during the acute phase of TTS and at follow-up both hemorheological parameters and biomarkers of endothelial damage, whose time course has never been fully explored.

Multivessel Disease Patients' Outcome and Second Generation Stent: Is Syntax Still a Valid Score? A Real-World Study from a Tertiary Center.

Objective: The SYNTAX trial was designed to evaluate whether multivessel disease patients could benefit from percutaneous or surgical revascularization using a paclitaxel eluting stents, but after the introduction of second generation stents, this score needs to be reevaluated. The aim of our study was to analyze the association between SYNTAX score and the prognosis of multivessel patients submitted to percutaneous coronary intervention (PCI) and second generation everolimus eluting stents (EES) implantation.

Materials And Methods: Data on 289 patients with multivessel coronary artery disease submitted to PCI with EES were stored in a dedicated database and retrospectively analyzed.

Six-month prognostic impact of hemodynamic profiling by short minimally invasive monitoring after cardiac surgery.

Studies have shown that a hemodynamic-guided therapy improves the post operative outcomes of high-risk patients.This study, evaluated if a short period through minimally invasive hemodynamic monitoring, pressure recording analytical method (PRAM), on admission to a post-cardiac surgery step-down unit (SDU), may identify patients at higher risk of 6-month adverse events after cardiac surgery. From December 2016-May 2017,173 patients were admitted in SDU within 24-48 hours of major cardiac surgery procedure, and submitted to clinical, laboratoristic and echocardiographic evaluation and a 1-hour PRAM recording to obtain a "biohumoral snapshot" of individual patient's.

Deep sedation vs femoral block anesthesia: beat-by-beat hemodynamic impact on TAVI procedure.

Background: In spite of the increased use of Trans-catheter Aortic Valve Implantation (TAVI) due to the better patient selection, well-trained operators and improved technology, the choice of the best anesthesia regimen remains an open question. In particular, it remains to be clarified whether deep sedation (DS) in spontaneous breathing or femoral local anesthesia (LA) is best.

Objective: This study compared the hemodynamic variations determined by deep sedation (DS) with spontaneous breathing and local femoral anesthesia (LA) in 2 groups of patients submitted to TAVI with two different kinds of anesthesia, using a beat-by-beat pulse contour method (MostCare).

Vulnerable struts with CRE8, Biomatrix and Xience stents assessed with OCT and their correlation with clinical variables at 6-month follow-up: the CREBX-OCT study.

First-generation drug eluting stents (DES) reduced the incidence of restenosis and need for repeated target lesion revascularization but, in autoptic studies, frequently resulted in incomplete endothelial coverage, which is an important predictor of late adverse events and increased mortality after stent implantation. More recently, not only uncovered, but also malapposed or protruding struts have been considered vulnerable structures, as they are deemed to perturb blood flow, whereas only struts well embedded into the vessel wall are considered stable. We compared the number of uncovered and of other vulnerable (protruding or malapposed) struts among three different second-generation drug-eluting stents (DES) (Cre8, Biomatrix, Xience), using optical coherence tomography (OCT) 6 months after implantation.

Prediction of functional recovery after primary PCI using the estimate of myocardial salvage in gated SPECT early after acute myocardial infarction.

Purpose: Primary percutaneous coronary intervention (PCI) in acute myocardial infarction (AMI) aims to achieve myocardial salvage (MS). Because the reference method for measuring MS requires myocardial perfusion imaging (MPI) after tracer injection before PCI, alternative approaches have been proposed, but none has gained wide acceptance. Gated SPECT MPI can assess infarct size (IS), but can also show myocardial stunning.

APpropriateness Assessment in Antiplatelet THerapY (APATHY) registry: Insight from current clinical practice.

Background: In clinical practice there is a gap between guidelines recommendation and antiplatelet strategies used for acute coronary syndrome (ACS). We sought to evaluate appropriateness of antiplatelet strategies employed in a tertiary center.

Methods And Results: From January to June 2014, 430 ACS were treated with percutaneous coronary intervention by 3 groups of interventional cardiologists.

Cystatin C, but not urinary or serum NGAL, may be associated with contrast induced nephropathy after percutaneous coronary invasive procedures: A single center experience on a limited number of patients.

Objective: This study aimed to test the association of both the baseline values and post-procedural variations of urinary and serum Neutrophil Gelatinase-Associated Lipocalin (NGAL) and Cystatin C (CysC) with contrast induced nephropathy (CIN) occurrence in patients undergoing percutaneous coronary invasive procedures (PCIP), and compare them to serum creatinine and the estimated glomerular filtration rate (eGFR).

Methods: In 43 patients admitted to our Cardiac Step-Down Unit and submitted to PCIP, we measured serum creatinine and eGFR as the standard markers for CIN diagnosis, and compared them to both serum and urinary NGAL as well as serum CysC, assessed before and 4 hours after PCIP.

Results: Patients who developed CIN (16%) were older, with significantly higher discharge creatinine values, lower eGFR values at creatinine peak, and higher baseline and post-PCIP CysC values.

Increased homocysteine and lipoprotein(a) levels highlight systemic atherosclerotic burden in patients with a history of acute coronary syndromes.

Background: Strong evidence supports an association between high levels of homocysteine (Hcy) and lipoprotein(a) [Lp(a)] and an increased rate of ischemic vascular events.

Methods: The study population comprised 162 patients (50 women [30.9%]; age, 66.

Prevalence of thrombophilic disorders in takotsubo patients: the (ThROmbophylia in TAkotsubo cardiomyopathy) TROTA study.

Takotsubo cardiomyopathy (TTC) pathophysiology is still unclear. A transient intracoronary thrombosis dissolved at the time of angiography has been hypothesized. We aimed to evaluate the prevalence of thrombophilic disorders in TTC patients.

Severe hypocalcemia and life-threatening ventricular arrhytmias: case report and proposal of a diagnostic and therapeutic algorithm.

Hypocalcemia is frequent in the setting of endocrine disorders, bone diseases and renal failure. When hypocalcemia is severe it can predispose to life-threatening ventricular arrhythmias; in such cases a rapid admission to hospital and a prompt correction of electrolyte imbalance are needed. We report the case of an old patient suffering from renal failure that was admitted to our cardiac step-down unit because of severe hypocalcemia associated with ventricular arrhythmias.

Aims: To compare the effects of two thrombus aspiration devices, the manual catheter Export® and the more complex and expensive mechanical Angiojet®, on several indices of reperfusion in acute ST-elevation myocardial infarction (STEMI).

Methods And Results: Clinical, hemodynamic and procedural characteristics of 185 STEMI patients, randomized to treatment with Export (n=95) or Angiojet (n=90) during primary percutaneous coronary intervention (PPCI) were analyzed. The primary endpoint was ST-segment elevation reduction 90 min after culprit vessel re-opening.

A time course study of high on treatment platelet reactivity in acute coronary syndrome male patients on dual antiplatelet therapy.

Introduction: Limited data are available on the natural history of high on treatment platelet reactivity (HPR) by arachidonic acid and ADP - markers of unfavorable prognosis in acute coronary syndrome patients -.

Material And Methods: In a cohort of acute coronary syndrome male patients (n=101), we evaluated the time-course of HPR by ADP (platelet aggregation by 10μM ADP≥70%) and arachidonic acid (platelet aggregation by 1mmol arachidonic acid≥20%) measuring platelet function in the acute phase (T0), at 6months (T1) and 1year (T2).

Results: We identified persistent (HPR at T0,T1 and T2), acute non persistent (HPR only at T0), and late (HPR only at T1 or T2).

Dual antiplatelet therapy tailored on platelet function test after coronary stent implantation: a real-world experience.

Patients' response to dual antiplatelet therapy (DAPT) is subject to variations and its monitoring allows to individualize this therapy. In this study, we evaluated if a strategy of tailored DAPT after platelet function testing could reduce high on-treatment platelet reactivity (HPR) and improve outcome of patients treated with stent implantation. In 257 patients undergoing percutaneous angioplasty, platelet function was measured by light transmittance aggregometry (LTA) using 10 µM/L adenosine-diphosphate (ADP) and 1 mM arachidonic acid (AA) as agonists.

Thrombus aspiration in ST-elevation myocardial infarction: Does it actually impact long-term outcome?

Background: The effect of thrombus aspiration on mortality is still controversial, with results which are often inconsistent in different randomized trials, real world registries and different follow-up duration. The aim of this analysis was to assess the effect on 30-day and 1-year mortality of thrombus aspiration during primary percutaneous coronary intervention (pPCI) for ST-elevation myocardial infarction (STEMI) compared with conventional PCI.

Methods: We used data from all the consecutive STEMI patients treated either with conventional PCI or thrombus aspiration between January 1, 2004 and January 1, 2012.

Comparison between drug-eluting and bare metal stent on ST-elevation myocardial infarction outcome: should second-generation drug-eluting stent be preferred?

Background And Purpose: Although several studies reported that drug-eluting stents (DES) are able to reduce restenosis incidence without increasing mortality, concerns still exist about their safety in ST-segment elevation myocardial infarction (STEMI) patients mainly for a possible higher rate of in-stent thrombosis. Recent evidence suggests a better safety profile of second-generation DES, but data on their outcome in STEMI are still poor. In this study we evaluated the impact on mortality and target lesion revascularization (TLR) of DES or bare metal stent (BMS) implantation in STEMI patients submitted to primary angioplasty.

Impact of hypertension history on short and long-term prognosis in patients with acute myocardial infarction treated with percutaneous angioplasty: comparison between STEMI and NSTEMI.

Previous studies analyzing the impact of hypertension (HTN) on myocardial infarction (MI) outcome reached conflicting results and scarce data are available in patients treated with percutaneous coronary intervention (PCI). In this study the prognostic impact of HTN history in ST-elevation MI (STEMI) and Non-STEMI (NSTEMI) patients treated with PCI was analyzed. We compared characteristics of 1,031 STEMI and 437 NSTEMI patients, in relation to the presence of HTN.

Congestive heart failure and decongestion ability of two different treatments: continuous renal replacement and diuretic therapy: experience of a cardiac step down unit.

Introduction: The rehospitalization rate for decompensated heart failure (HF) is high and can be ascribed also to a suboptimal decongestion before discharge. Congestion can be treated with diuretics or continuous renal replacement therapy (CRRT). Aim of this study was to evaluate if diuretics and CRRT, used in agreement to international guidelines, may have a dissimilar decongestion ability in patients with decompensated HF with different baseline characteristics.

Safety and effectiveness of combined percutaneous coronary angioplasty and aortic valvuloplasty in an elderly patient with cardiogenic shock: effect on concomitant severe mitral regurgitation.

An 80-year-old diabetic man with severe aortic stenosis was admitted to our hospital for cardiogenic shock complicating non-ST-elevation myocardial infarction. Echocardiographic evaluation showed also a severe degree of both left ventricular dysfunction and mitral regurgitation. The patient was initially stabilized with inotropes and mechanical ventilation was necessary because of concurrent pulmonary edema.

Prognostic impact of atrial fibrillation occurrence in patients with non-ST-elevation acute coronary syndromes: is dysrhythmia duration a parameter to focus on?

Several studies have evaluated the prognostic impact of atrial fibrillation (AF) in ST-elevation myocardial infarction (STEMI) patients, but scarce data are available on the role of AF in non-ST-elevation acute coronary syndromes (NSTE-ACS). The aim of this study was to investigate long-term outcome of NSTE-ACS patients experiencing an episode of AF during in-hospital course. Of 1,147 NSTE-ACS patients, 54.
