Polymorphonuclear leukocyte membrane fluidity and cytosolic Ca2+ content in young adults with acute myocardial infarction. Evaluation at the initial …

2004

Our aim was to examine two aspects of polymorphonuclear leukocyte (PMN) rheology (membrane fluidity and cytosolic Ca2+ content), at baseline and after in vitro activation, in a group of young adults with acute myocardial infarction (AMI) at the initial stage and after 12 months. We enrolled 21 AMI subjects aged < or = 45 years (mean age 41.1 +/- 3.5 years) and evaluated PMN membrane fluidity, labelling intact PMN cells with the fluorescent probe 1,4-(trimethylamino)-phenyl-4-phenylhexatriene and the PMN cytosolic Ca2+ content marking PMN cells with the fluorescent probe Fura 2-AM, at baseline and after in vitro activation with 4-phorbol 12-myristate 13-acetate (PMA) and N-formyl-methionyl-l…

Randomised comparison of zofenopril and ramipril plus acetylsalicylic acid in postmyocardial infarction patients with left ventricular systolic dysfu…

2015

Objective Conflicting evidence exists on the benefits of treating patients with coronary artery disease and preserved left ventricular ejection fraction (LVEF) with an ACE inhibitor. This retrospective analysis of the SMILE-4 Study sought to compare the efficacy of zofenopril 60 mg plus acetylsalicylic acid (ASA) versus ramipril 10 mg plus ASA 100 mg in patients with acute myocardial infarction (AMI) and heart failure, according to an impaired or preserved LVEF. Methods The primary study end point was 1-year combined occurrence of death or hospitalisation for cardiovascular causes. A preserved LVEF was defined by a baseline LVEF >40% and an impaired one by an LVEF ≤40%. Results 448 patients…

Electrocardiographic, angiographic and clinical picture of acute myocardial infarction with ST-segment elevation caused by simultaneous occlusion of …

2018

Acute myocardial infraction with ST-segment elevation (STEMI) is most often caused by the occlusion of only one large epicardial artery. Simultaneous thrombosis of two or more coronary arteries is a rare cause of STEMI. In this article, the authors present a case of a 56-year-old man with STEMI who was diagnosed with simultaneous occlusion of the right coronary artery and the left anterior descending branch of the left coronary artery

Real-Life Outcomes of Coronary Bifurcation Stenting in Acute Myocardial Infarction (Zabrze–Opole Registry)

2021

Percutaneous coronary intervention (PCI) of bifurcation lesions is a technical challenge associated with high risk of adverse events, especially in primary PCI. The aim of the study is to analyze long-term outcomes after PCI for coronary bifurcation in acute myocardial infarction (AMI). The outcome was defined as the rate of major adverse cardiac event related to target lesion failure (MACE-TLF) (death-TLF, nonfatal myocardial infarction-TLF and target lesion revascularization (TLR)) and the rate of stent thrombosis (ST). From 306 patients enrolled to the registry, 113 were diagnosed with AMI. In the long term, AMI was not a risk factor for MACE-TLF. The risk of MACE-TLF was dependent on th…

Risk Burden of Coronary Perforation in Chronic Total Occlusion Recanalization: Latin American CTO Registry Analysis

2022

Background Coronary perforation is a life‐threatening complication of acute percutaneous coronary intervention (PCI) for chronic total occlusions (CTO), but data on midterm outcomes are limited. Methods and Results Data from LATAM (Latin American)‐CTO Registry (57 centers; 9 countries) were analyzed. We assessed the risk of 30‐day, 1‐year major adverse cardiac events of coronary perforation using time‐to‐event and weighted composite end point analysis having CTO PCI without perforation as comparators. Additionally, we studied the independent predictors of perforation in these patients. Of 2054 patients who underwent CTO PCI between 2015 and 2018, the median Multicenter CTO Registry in Japa…

Iron metabolism markers and l-arginine derivatives in coronary artery disease : highlighting, assessment and role of oxidative stress in acute myocar…

2015

Myocardial infarction (MI) is mostly caused by complications of atherosclerosis, whose the development would be initiated by a dysfunction of the vascular endothelium, characterized by an inflammatory condition and oxidative stress.In this pathogenesis, iron interacts at different levels and also has a major role in the development of endothelial dysfunction. Hepcidin and erythroferrone (discovered earlier as the myonectin/CTRP 15) participate in a major way in regulating certain stages of iron metabolism.Asymmetric dimethylarginine (ADMA), a marker of endothelial dysfunction is associated with most cardiovascular risk factors. Symmetrical dimethyl-arginine (SDMA), its stereoisomer, has an …

Post-traumatic Stress Disorder and Risk Factors in Patients With Acute Myocardial Infarction After Emergency Percutaneous Coronary Intervention: A Lo…

2021

This study aimed to investigate the status and risk factors of post-traumatic stress disorder (PTSD) in patients with acute myocardial infarction (AMI) after emergency percutaneous coronary intervention (PCI) in acute and convalescence phases. A longitudinal study design was used. Two questionnaire surveys were conducted in the acute stage of hospitalization, and 3 months after onset in patients. Logistic regression was used to analyze the risk factors for PTSD in AMI patients. The incidence of PTSD was 33.1 and 20.4% in acute and convalescent patients, respectively. The risk factors related to PTSD were door-to-balloon time (DTB) (≥92.6 min), left ventricular ejection fraction (LVEF) (&amp…

Causal and Non-Causal Frequency Domain Assessment of Spontaneous Baroreflex Sensitivity after Myocardial Infarction

2020

Acute myocardial infarction (AMI) is thought to alter the baroreflex control of arterial pressure. We tested this hypothesis investigating the changes of the cardiovascular response after AMI in comparison with young and old healthy controls studied at rest and during head-up tilt, using causal and non-causal frequency domain measures of the baroreflex sensitivity. Our results indicate: (i) the importance of using a causal approach that takes into account not only feedback but also feedforward effects in the study of interactions between the heart period and the arterial pressure; (ii) the compromised capacity of baroreceptors to control SAP fluctuations in post-AMI patients, both at rest a…
