Secondary adherence to beta-blockers after ST-elevation myocardial infarction without ventricular dysfunction.

2020

Introduction and objectives: Adequate medication intake affects treatment effectiveness. The aim of this study was to establish the impact of prescription and secondary adherence to beta-blockers on medium-and long-term and long-term cardiovascular outcomes, after a first type 1 ST-elevation myocardial infarction (STEMI) episode without heart failure or left ventricular ejection fraction >= 40%. Methods: A retrospective observational study was conducted in a cohort of patients admitted from 2008 to 2013 to the University Clinical Hospital in Valencia. Competing risk analysis assessed the relationship between cardiovascular mortality or new vascular event with beta-blocker prescription and s…

Safety and efficacy of biodegradable polymer-coated thin strut sirolimus-eluting stent vs. durable polymer-coated everolimus-eluting stent in patient…

2018

Introduction The biodegradable polymer drug-eluting stents were developed to improve vascular healing. However, further data are needed to confirm the safety and efficacy of these stents in patients with acute myocardial infarction (AMI). Aim We sought to determine the 1-year clinical follow-up in patients with AMI treated with a thin strut biodegradable polymer-coated sirolimus-eluting stent (BP-SES) versus a durable coating everolimus-eluting stent (DP-EES). Material and methods We analyzed patients with AMI (STEMI and NSTEMI) treated with either a BP-SES (ALEX, Balton, Poland, n = 886) or DP-EES (XIENCE, Abbott, USA, n = 1054) with available 1-year clinical follow-up using propensity sco…

Non Invasive Imaging of Myocardial Infarction with Computed Tomography and Magnetic Resonance

2012

Myocardial infarction is a major cause of death and disability worldwide. Myocardial infarction may represent a major catastrophic event leading to severe hemodynamic failure or sudden death or it may occur repeatedly in patients with established heart disease. In this context, the role of imaging techniques may become useful for the understanding of the determinants in a preclinical setting before acute coronary events, and for an accurate and correct diagnosis of myocardial infarction. Three-dimensional noninvasive imaging techniques, such as Cardiac CT (CCT) and Cardiac MR imaging (CMR) were widely developed in the last two decades. These imaging techniques may provide new insights into …

Magnetic Resonance Assessment of Left Ventricular Ejection Fraction at Any Time Post-Infarction for Prediction of Subsequent Events in a Large Multic…

2021

Background Magnetic resonance imaging (MRI) is the most accurate imaging technique for left ventricular ejection fraction (LVEF) quantification, but as yet the prognostic value of LVEF assessment at any time after ST-segment elevation myocardial infarction (STEMI) for subsequent major adverse cardiac event (MACE) prediction is uncertain. Purpose To explore the prognostic impact of MRI-derived LVEF at any time post-STEMI to predict subsequent MACE (cardiovascular death or re-admission for acute heart failure). Study Type Prospective. Population One thousand thirteen STEMI patients were included in a multicenter registry. Field Strength/Sequence 1.5-T. Balanced steady-state free precession (c…

Gender-related disparities in the treatment and outcomes in patients with non-ST-segment elevation myocardial infarction: results from the Polish Reg…

2017

Introduction: Gender-related differences in the treatment of patients with non-ST elevation myocardial infarction (NSTEMI) have been reported in many previous studies despite the fact that an equal approach is recommended in all current guidelines. The aim of the study was to investigate whether gender-related discrepancies in the management of NSTEMI patients have changed. Material and methods: Between 2012 and 2014 a total of 66,667 patients (38.3% of whom were women) with the final diagnosis of NSTEMI were included into the retrospective analysis of the Polish Registry of Acute Coronary Syndromes (PL-ACS). Differences in clinical profile, treatment, and outcomes were analysed. Results: W…

Cardiovascular risk and events in polycystic ovary syndrome

2009

Young women with polycystic ovary syndrome (PCOS) present a high risk for cardiovascular disease because of the presence of abdominal obesity, insulin resistance and androgen excess. In addition, they present with endothelial dysfunction and early signs of atherosclerosis (increased carotid intima-media thickness and increased coronary calcium). However, the evidence of increased cardiovascular events during the postmenopausal age is relatively small, although some recent studies have indicated a slight increase in the severity of cardiovascular disease in women who had PCOS during their fertile age. The discrepancy between cardiovascular risk in young age and postmenopausal cardiovascular …

Cardiac computed tomography assessment of the near term impact of percutaneous ventricular restoration therapy (parachute®) on mitral valve geometry

2015

Objectives The aim of current study is to assess the near term impact of percutaneous ventricular restoration therapy (PVR), Parachute® on mitral valve (MV) geometry by cardiac computed tomography (CCT). Background Recent data demonstrates the feasibility of PVR for treatment of post anterior myocardial infarction (MI) heart failure. Little is known, however, about the interaction of the device and left ventricular structures, particularly the MV apparatus. Methods This is a retrospective Core Laboratory analysis of Parachute Trials’ CCT data. Patients with paired (before and after Parachute implant) CCT acquisitions were included into analysis. MV geometric parameters were measured. Result…

Evaluating the quality of implantation of percutaneous ventricular restoration device (Parachute®) by cardiac computed tomography

2016

Background The Parachute is a novel percutaneously implanted ventricular partitioning device (VPD) that has emerged as a safe and feasible treatment option for patients with heart failure following anterior wall myocardial infarction. VPD efficacy is likely dependent on optimal device placement, but to date there are no published data examining the effect of device positioning on patient outcomes. Methods and results We retrospectively identified 32 patients successfully implanted with the Parachute device, all of whom underwent cardiac computed tomography (CCT) at baseline and after 6 months of follow-up. Patients were divided into two groups based on self-reported improvement in New York …
