Background: The impact of performing a primary percutaneous coronary intervention (pPCI) off-hours on clinical outcomes is not well established.
Objective: Compare characteristics and major adverse cardiovascular events (MACE) of pPCI off-hours versus on-hours in a high-volume cardiology center.
Methods: Prospective cohort of patients who underwent pPCI for ST elevation myocardial infarction (STEMI) from 2009 to 2019.
Overview of Percutaneous Coronary Interventions for Chronic Total Occlusions Treated at Brazilian Centers Participating in the LATAM CTO Registry.
Arq Bras Cardiol
May 2023
Background: Major advances have been seen in techniques and devices for performing percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs), but there are limited real-world practice data from developing countries.
Objectives: To report clinical and angiographic characteristics, procedural aspects, and clinical outcomes of CTO PCI performed at dedicated centers in Brazil.
Methods: Included patients underwent CTO PCI at centers participating in the LATAM CTO Registry, a Latin American multicenter registry dedicated to prospective collection of these data.
Objective: This study's aim was to verify whether a psychoeducational intervention, with a brief expressive posttraumatic growth (PTG) component, could reduce heart failure (HF) patients' hospital readmissions and promote their quality of life (QoL) and PTG.
Methods: It adopted a parallel randomized clinical trial design, and its participants comprised HF patients from a hospital in Southern Brazil. All the participants completed the World Health Organization Quality of Life Assessment and Posttraumatic Growth Inventory questionnaires at the pre (T1: baseline) and post (T2) assessments of the intervention.
Background And Aims: The dynamics and implications of intracoronary thrombus constituency in patients with ST-segment elevation myocardial infarction (STEMI) are not fully understood. We evaluated the expression of CD34, CD61and factor VIII surface markers in thrombi of patients with STEMI and its association with clinical and angiographic characteristics and major adverse cardiovascular events (MACE).
Methods: Patients presenting with STEMI undergoing aspiration thrombectomy during primary percutaneous coronary intervention (pPCI) were included.
Outcomes of chronic total occlusion percutaneous coronary intervention in patients with prior coronary artery bypass graft surgery: Insights from the LATAM CTO registry.
Catheter Cardiovasc Interv
February 2022
Article Synopsis
- The study aimed to assess the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in patients with and without prior coronary artery bypass graft (CABG) surgery.
- Data was collected from a Latin American registry involving 1,662 patients between 2008 and 2020, comparing those with prior CABG (15.1%) to those without (84.9%).
- Findings indicated that prior-CABG patients were older, had more health issues, and faced more challenges during procedures, though the overall risk of serious complications during hospitalization was similar between both groups.
The Influence of Cognitive Behavioral Intervention for Anger Management on Endothelial Function in Patients With Recent Myocardial Infarction: A Randomized Clinical Trial.
Psychosom Med
March 2022
Objective: Anger may cause adverse cardiovascular responses, but the effects of anger management on clinical cardiovascular outcomes are insufficiently understood. We sought to assess the influence of anger management through a cognitive behavioral intervention on endothelial function in patients with a recent myocardial infarction (MI).
Methods: Patients with ST-elevation MI and a low anger control score were enrolled during hospitalization in a randomized, parallel, controlled clinical trial.
Background: Women seem to be more susceptible to psychosocial stress than men, and stress is associated with worse outcomes after acute myocardial infarction (AMI).
Objectives: To investigate whether the female gender is an independent predictor of risk for stress and to compare stress levels between women and men after AMI.
Methods: Cross-sectional study of a case series.
Background: Multicenter registries representing the real world can be a significant source of information, but few studies exist describing the methodology to implement these tools.
Objective: To describe the process of implementing a database of ST-segment elevation acute myocardial infarction (STEMI) at a reference hospital, and the application of this process to other centers by means of an online platform.
Methods: In 2009, our institution implemented an Registry of Acute Myocardial Infarction (RIAM), with the prospective and consecutive inclusion of every patient admitted to the institution who received a diagnosis of STEMI.
Background: In patients with acute ST-segment elevation myocardial infarction (STEMI), the time elapsed from symptom onset to receiving medical care is one of the main mortality predictors.
Objective: To identify independent predictors of late presentation in patients STEMI representative of daily clinical practice.
Methods: All patients admitted with a diagnosis of STEMI in a reference center between December 2009 and November 2014 were evaluated and prospectively followed during hospitalization and for 30 days after discharge.
Background: Anger control was significantly lower in patients with coronary artery disease (CAD), regardless of traditionally known risk factors, occurrence of prior events or other anger aspects in a previous study of our research group.
Objective: To assess the association between anger and CAD, its clinical course and predictors of low anger control in women submitted to coronary angiography.
Methods: This is a cohort prospective study.
Background: Contemporary studies assessing the frequency, characteristics, and outcomes of serious infections (SIs) in patients presenting a ST-elevation myocardial infarction are scarce.
Methods: Prospective cohort of consecutive patients undergoing primary percutaneous coronary intervention (pPCI). Serious infection was defined as the presence of infection that prolonged hospitalization.
In patients with ST-elevation myocardial infarction, recurrent cardiovascular events still remain the main cause of morbidity and mortality, despite significant improvements in antithrombotic therapy. We sought to review data regarding coronary thrombus analysis provided by studies using manual aspiration thrombectomy (AT), and to discuss how insights from this line of investigation could further improve management of acute coronary disease. Several studies investigated the fresh specimens retrieved by AT using techniques such as traditional morphological evaluation, optical microscopy, scanning electron microscopy, magnetic resonance imaging, and immunohistochemistry.

Am Heart J
February 2016
Background: Although diabetes mellitus (DM) is a predictor of poor outcomes in patients with ST-segment elevation myocardial infarction (STEMI), few studies have analyzed the impact of DM on the constituency of coronary thrombi.
Objectives: Comparing morphologic and histopathologic aspects of coronary thrombi in STEMI patients with and without DM who underwent primary percutaneous coronary intervention.
Methods: All consecutive patients with STEMI admitted to our institution between April 2010 and December 2012 (n = 1,548) were considered for inclusion.
