Erythrocyte Indices in Patients With Takotsubo Syndrome.

Background: Although the prognosis of patients with Takotsubo syndrome (TTS) is relatively favorable, serious complications may occur. This study aimed to investigate the relationship between blood parameters and the occurrence of in-hospital complications.

Methods: Clinical charts of 51 patients with TTS were retrospectively evaluated, and data regarding blood parameters assessed during the first 24 hours of hospitalization were studied.

A 'parachute effect' mockingly sealing a spontaneous coronary artery dissection: what we have learnt from intravascular imaging.

Spontaneous coronary artery dissection is often underdiagnosed. It accounts for a certain amount of acute coronary syndromes. Intravascular imaging, either intravascular ultrasound or optical coherence tomography, represents a relevant ally for interventional cardiologist.

Association between Tpeak-Tend/QT and major adverse cardiovascular events in patients with Takotsubo syndrome.

Background: Conflicting results have been described in the scientific literature regarding the relationship between electrocardiographic parameters and complications in patients with Takotsubo syndrome (TTS). Aim of the present study was to investigate whether there is an association between markers of ventricular repolarization and major adverse cardiovascular events (MACE) during hospitalisation.

Methods: A retrospective chart review was conducted on a sample of patients with diagnosis of TTS, based on the fulfilment of the revised Mayo Clinic criteria.

Optimal duration of dual antiplatelet therapy after second-generation drug-eluting stent implantation in patients with diabetes: The SECURITY (Second-Generation Drug-Eluting Stent Implantation Followed By Six- Versus Twelve-Month Dual Antiplatelet Therapy)-diabetes substudy.

Background/objectives: The randomized SECURITY (Second-Generation Drug-Eluting Stent Implantation Followed by Six- Versus Twelve-Month Dual Antiplatelet Therapy) trial showed the non-inferiority of 6 vs. 12-month DAPT after percutaneous coronary intervention (PCI) with second-generation DES in a low-risk population. Nevertheless, diabetes mellitus (DM) remained a major predictor of adverse cardiovascular events.

Second-generation drug-eluting stent implantation followed by 6- versus 12-month dual antiplatelet therapy: the SECURITY randomized clinical trial.

Background: The optimal duration of dual antiplatelet therapy (DAPT) following second-generation drug-eluting stent (DES) implantation is still debated.

Objectives: The aim of this study was to test the noninferiority of 6 versus 12 months of DAPT in patients undergoing percutaneous coronary intervention with second-generation DES.

Methods: The SECURITY (Second Generation Drug-Eluting Stent Implantation Followed by Six- Versus Twelve-Month Dual Antiplatelet Therapy) trial was a 1:1 randomized, multicenter, international, investigator-driven, noninferiority study conducted from July 2009 to June 2014.

Small, dense low-density lipoproteins (LDL) are predictors of cardio- and cerebro-vascular events in subjects with the metabolic syndrome.

Objective: Small, dense low-density lipoproteins (LDL) are a feature of the metabolic syndrome (MS) but their predictive role still remains to be established. We performed a 2-year follow-up study in 124 subjects with MS (63 +/- 6 years), as defined by the American Heart Association/National Heart, Lung and Blood Institute guidelines, to assess clinical and biochemical predictors of cerebro- and cardio-vascular events.

Methods And Results: Beyond traditional cardiovascular risk factors, we measured LDL size and subclasses by gradient gel electrophoresis.

LDL size and subclasses in patients with abdominal aortic aneurysm.

Since the type of dyslipidemia in patients with abdominal aortic aneurysm (AAA) is still insufficiently defined, we measured plasma lipids and analyzed LDL size and subclasses by gradient gel electrophoresis in 30 male patients (69+/-6 years, BMI: 27+/-3) with newly diagnosed AAA and in 26 age- and BMI-matched male healthy controls. Patients with AAA had lower HDL-cholesterol (p<.0001), increased triglycerides (p=.

Atherogenic lipoprotein phenotype and LDL size and subclasses in patients with peripheral arterial disease.

The type of dyslipidemia in patients with peripheral arterial disease (PAD) is still ill defined. PAD patients often show elevated triglycerides and reduced HDL-cholesterol, two lipid abnormalities usually accompanied by decreased LDL size in the "atherogenic lipoprotein phenotype" (ALP). We investigated (1) whether PAD patients have lower LDL size, (2) altered LDL subclass distribution and (3) the prevalence of ALP.

Accumulation of apoE-enriched triglyceride-rich lipoproteins in patients with coronary artery disease.

Triglycerides (TGs) are vehicled by multiple particles with different abilities to promote atherosclerosis. Among plasma TG-rich lipoproteins (TRLs), subspecies may or may not contain apolipoprotein E (apoE) molecules: in this study, we evaluated the relative contribution of apoE-rich and apoE-poor TRLs to coronary atherosclerosis. We selected a group of males with premature coronary artery disease (CAD) without any of the classical nonlipid risk factors and/or high plasma lipid levels and evaluated the plasma concentration of TRL subspecies in comparison with healthy controls.

Family history, diabetes and extension of coronary atherosclerosis are strong predictors of adverse events after PTCA: A one-year follow-up study.

Background And Aim: In this study we addressed some open questions in patients with coronary artery disease (CAD). First, we analysed which of the traditional risk factors was associated with the spreading of coronary stenosis and second, we aimed to identify if any variable was predictive of post-percutaneous transluminal coronary angioplasty (PTCA) clinical events.

Methods And Results: We collected a consecutive series of patients with CAD (n=301) and in the subgroup of patients undergoing PTCA (n=135) we performed a prospective one-year follow-up study recording cardiovascular morbidity and total mortality.

[Potential impact of drug-eluting stents in Sicily: results from a multicenter survey and cost-benefit analysis of drug-eluting stents versus bare metal stents].

Background: The recent introduction of drug-eluting stents (DES) has shown, in randomized controlled trials, to reduce the incidence of restenosis as compared to bare metal stents (BMS). Since their cost is considerably higher than that of BMS, the study assessed the economic impact of the adoption of this new therapy in the Sicilian clinical practice.

Methods: An economic evaluation was carried out by means of a linear decision model developed in Excel that simulated and compared costs and clinical pathway, within 1 year of the intervention, of hypothetical groups of patients with de novo lesions undergoing angioplasty with DES or BMS.

Cutting balloon versus conventional balloon angioplasty for the treatment of in-stent restenosis: results of the restenosis cutting balloon evaluation trial (RESCUT).

Objectives: The aim of this trial was to compare cutting balloon angioplasty (CBA) with conventional balloon angioplasty (i.e., percutaneous transluminal coronary angioplasty [PTCA]) for the treatment of patients with coronary in-stent restenosis (ISR).

A randomized comparison of direct stenting versus stenting with predilatation in native coronary artery disease: results from the multicentric Crosscut study.

Stenting without predilatation has become possible due to the availability of a new generation of flexible, low-profile, securely crimped, balloon-expandable stents. This study compared the feasibility, efficacy and cost-effectiveness of direct stenting (DS) to the standard predilatation technique (PS) using the premounted Crossflex LC stent (Cordis Corporation, Miami Lakes, Florida). The study is a randomized prospective multicenter evaluation including 271 patients (140 patients in the DS group and 131 patients in the PS group) with 1 or 2 de novo or restenotic lesions located in native coronary arteries.

Elective stenting in small coronary arteries: results of the Italian prospective multicenter registry MICROSCOPE.

Background: The role of stent implantation in small coronary arteries is still controversial. The MICROSCOPE study (Ministenting in small coronary arteries, a prospective evaluation) is a multicenter registry addressed to prospectively evaluate the immediate and mid-term clinical and angiographic results of elective stenting of lesions located in coronary arteries with an angiographic reference diameter < or = 2.75 mm.
