Prognostic comparison between creatinine-based glomerular filtration rate formulas for the prediction of 10-year outcome in patients with non-ST elevation acute coronary syndrome treated by percutaneous coronary intervention.

Background:: Estimated glomerular filtration rate (eGFR) is a predictor of outcome among patients with non-ST-elevation acute coronary syndrome (NSTE-ACS), but which estimation formula provides the best long-term risk stratification in this setting is still unclear. We compared the prognostic performance of four creatinine-based formulas for the prediction of 10-year outcome in a NSTE-ACS population treated by percutaneous coronary intervention.

Methods:: In 222 NSTE-ACS patients submitted to percutaneous coronary intervention, eGFR was calculated using four formulas: Cockcroft-Gault, re-expressed modification of diet in renal disease (MDRD), chronic kidney disease epidemiology collaboration (CKD-Epi), and Mayo-quadratic.

Diabetic Foot Infection: Preliminary Results of a Fast-Track Program with Early Endovascular Revascularization and Local Surgical Treatment.

Background: To demonstrate that a fast-track program consisting in early endovascular revascularization and local surgical treatment saves tissue in patients with diabetic foot infection (DFI).

Methods: Between January and December 2014, 48 patients with DFI underwent early endovascular revascularization and local surgical treatment at our Diabetic Foot Center. In all cases, endovascular revascularization and local surgical treatment were performed within 1 week from the diagnosis of infection and during the same hospital stay.

Nightmare-induced atypical midventricular tako-tsubo cardiomyopathy.

Tako-Tsubo cardiomyopathy (TTC) is a reversible cardiomyopathy characterized by acute left ventricular segmental dysfunction, whose clinical presentation resembles that of acute myocardial infarction. The syndrome often follows a psychophysical stressful event and is characterized by echocardiographic evidence of akinesia of the left ventricular mid-apical segments. Atypical echocardiographic patterns of TTC have recently been described, often triggered by emotional stressors, rather than physical.

Coronary thrombus in patients undergoing primary PCI for STEMI: Prognostic significance and management.

Acute ST-elevation myocardial infarction (STEMI) usually results from coronary atherosclerotic plaque disruption with superimposed thrombus formation. Detection of coronary thrombi is a poor prognostic indicator, which is mostly proportional to their size and composition. Particularly, intracoronary thrombi impair both epicardial blood flow and myocardial perfusion, by occluding major coronary arteries and causing distal embolization, respectively.

Paclitaxel-eluting versus bare metal stents in primary PCI: a pooled patient-level meta-analysis of randomized trials.

Concerns have emerged regarding a higher risk of stent thrombosis after drug-eluting stent (DES) implantation, especially in the setting of ST-segment elevation myocardial infarction (STEMI). Therefore, we performed a meta-analysis based on individual patient data to evaluate long-term safety and effectiveness of paclitaxel-eluting stent (PES) as compared to bare metal stents (BMS) in patients undergoing primary percutaneous coronary intervention (PCI) for STEMI. We examined all completed randomized trials on PES for STEMI.

Impact of hypertension on clinical outcome in STEMI patients undergoing primary angioplasty with BMS or DES: insights from the DESERT cooperation.

Background: Hypertension is a well known risk factor for atherosclerosis. However, data on the prognostic impact of hypertension in patients with ST elevation myocardial infarction (STEMI) are inconsistent and mainly related to studies performed in the thrombolytic era, with very few data in patients undergoing primary angioplasty. Therefore, the aim of the current study was to evaluate the impact hypertension on clinical outcome in STEMI patients undergoing primary PCI with BMS or DES.

Drug-eluting stents in patients with anterior STEMI undergoing primary angioplasty: a substudy of the DESERT cooperation.

Background: Several concerns have emerged on the higher risk of in-stent thrombosis after drug-eluting stent (DES) implantation, especially in the setting of STEMI patients. Few data have even been reported in high-risk patients, such as those with anterior MI. Therefore this represents the aim of the current study.

Gender-related differences in outcome after BMS or DES implantation in patients with ST-segment elevation myocardial infarction treated by primary angioplasty: insights from the DESERT cooperation.

Background: Several studies have found that among patients with ST-segment elevation myocardial infarction (STEMI) treated by thrombolysis, female sex is associated with a worse outcome. However, still controversial is the prognostic impact of gender in primary angioplasty, especially in the era of drug-eluting stents (DES). Therefore, the aim of this study was to investigate sex-related differences in clinical outcome in patients with STEMI treated with primary angioplasty with Bare-Metal Stent (BMS) or DES.

Time course, predictors and clinical implications of stent thrombosis following primary angioplasty. Insights from the DESERT cooperation.

Primary percutaneous coronary intervention (pPCI) has improved survival as compared to thrombolysis. Concerns still remain regarding the risk of stent thrombosis in the setting of STEMI, especially after drug-eluting stent (DES) implantation. Therefore, the aim of this study was to report on the timing of stent thrombosis (ST) with both DES and bare metal stents (BMS) and its prognostic significance in patients undergoing pPCI.

Impact of age on long-term outcome after primary angioplasty with bare-metal or drug-eluting stent (from the DESERT cooperation).

Despite mechanical reperfusion, elderly patients with ST-segment elevation myocardial infarction (STEMI) still experience unsatisfactory outcomes. Drug-eluting stents (DES) have significantly reduced target-vessel revascularization (TVR), but concerns have emerged about the higher risk of late stent thrombosis, which may be more pronounced in elderly patients. Therefore, the aim of this study was to evaluate the impact of age on outcome in patients with STEMI who underwent primary angioplasty with bare-metal stents (BMS) or DES.

Meta-analysis comparing efficacy and safety of first generation drug-eluting stents to bare-metal stents in patients with diabetes mellitus undergoing primary percutaneous coronary intervention.

Several concerns have emerged regarding the higher risk for stent thrombosis (ST) after drug-eluting stent (DES) implantation, especially in the setting of ST-segment elevation myocardial infarction (STEMI). Few data have been reported so far in patients with diabetes mellitus, which is associated with high rates of target vessel revascularization after bare-metal stent (BMS) implantation but also higher rates of ST after DES implantation. Therefore, the aim of this study was to perform a meta-analysis of individual patients' data to evaluate the long-term safety and effectiveness of DES compared with BMS in patients with diabetes who undergo primary percutaneous coronary intervention for STEMI.

Impact of diabetes on long-term outcome after primary angioplasty: insights from the DESERT cooperation.

Objective: Diabetes has been shown to be associated with worse survival and repeat target vessel revascularization (TVR) after primary angioplasty. The aim of the current study was to evaluate the impact of diabetes on long-term outcome in patients undergoing primary angioplasty treated with bare metal stents (BMS) and drug-eluting stents (DES).

Research Design And Methods: Our population is represented by 6,298 ST-segment elevation myocardial infarction (STEMI) patients undergoing primary angioplasty included in the DESERT database from 11 randomized trials comparing DES with BMS.

Subclavian steal syndrome presenting as recurrent pulmonary oedema associated with acute left ventricular diastolic dysfunction.

Subclavian steal syndrome typically presents as angina in patients with internal mammary artery grafts. Atypical clinical presentations have been rarely described. We report an unusual case of subclavian steal syndrome presenting as pulmonary oedema with acute left ventricular diastolic dysfunction and preserved ejection fraction in a patient with internal mammary artery graft and severe stenosis of the proximal left subclavian artery.

Drug-eluting vs bare-metal stents in primary angioplasty: a pooled patient-level meta-analysis of randomized trials.

Background: Concerns have emerged regarding a higher risk of stent thrombosis after drug-eluting stent (DES) implantation, especially in the setting of ST-segment elevation myocardial infarction (STEMI).

Mechanisms of late stent malapposition after primary stenting in ST-elevation myocardial infarction: a subanalysis of the selection trial.

Background: One of the major predictors of late stent malapposition (LSM) is primary stenting in acute myocardial infarction. However, mechanisms of LSM are still under debate.

Methods: Patients with ST-elevation myocardial infarction (STEMI) and enrolled in the SELECTION trial (38 patients in the paclitaxel-eluting stent, PES, and 35 in the bare metal stent, BMS, cohort) were retrospectively analyzed to evaluate LSM, by means of intravascular ultrasound (IVUS) data recorded at the index and 7-month follow-up procedures.

Rheolytic thrombectomy in patients with massive and submassive acute pulmonary embolism.

Objectives: To appraise the impact of AngioJet rheolytic thrombectomy (RT) on angiographic and clinical endpoints in patients with acute pulmonary embolism (PE).

Background: The management of patients with acute PE and hemodynamic compromise, based mainly on anticoagulant and thrombolytic therapies, is challenging and still suboptimal in many patients. In such a setting, mechanical removal of thrombus from pulmonary circulation holds the promise of significant clinical benefits, albeit remains under debate.

[Percutaneous rheolytic thrombectomy with AngioJet for pulmonary embolism: methods and results in the experience of a high-volume center].

Background: Pulmonary embolism is a common disease with significant mortality. Anticoagulant and thrombolytic therapies are a mainstay in the management of acute pulmonary embolism, especially with hemodynamic compromise. However, systemic drugs cannot achieve timely and effective treatment of acute pulmonary embolism in all patients.

ST-segment elevation myocardial infarction due to early and late stent thrombosis a new group of high-risk patients.

Objectives: The aim of this retrospective study was to compare clinical and angiographic outcomes between patients presenting with ST-segment elevation myocardial infarction (STEMI) due to stent thrombosis (ST) and de novo coronary thrombosis.

Background: There are limited data for procedural and mid-term outcomes of patients with ST presenting with STEMI.

Methods: From January 2004 to March 2007, 115 definite ST patients were observed: 92 (80%) of them presented as STEMI and were compared with a consecutive group of 98 patients with de novo STEMI.

Severe diffuse coronary artery spasm in the early phase of cardiogenic shock.

Coronary artery vasospasm rarely appears as a diffuse phenomenon that involves all the coronary tree. We present a clinical case of acute myocardial infarction complicated by ventricular fibrillation and cardiogenic shock. Urgent coronary angiography showed occlusion of proximal Circumflex coronary artery and a TIMI I flow in the left anterior descending artery due to severe, diffuse coronary vasospasm.

Early and long-term clinical results of AngioJet rheolytic thrombectomy in patients with acute pulmonary embolism.

Anticoagulant and thrombolytic therapies are a mainstay in the management of acute pulmonary embolism (PE), especially when hemodynamic compromise is present. However, systemic drugs cannot achieve timely and effective treatment of acute PE in all patients. In such a setting, mechanical removal of thrombus from the pulmonary circulation holds the promise of significant clinical benefits, although it remains untested.
