Abstract Background: Distal transradial access (dTRA), an improvement of the conventional proximal transradial access (pTRA), has advantages in terms of faster hemostasis and lower rates of proximal radial artery occlusion (RAO). Objectives: We aim to describe our real-world experience with dTRA as the default approach for routine coronary angiography and percutaneous coronary interventions (PCI) in a large-scale sample of all-comers patients. Methods: From February 2019 to April 2024, 6,800 consecutive patients undergoing coronary procedures via dTRA were enrolled in the […]

Abstract Background Femoral access remains a common choice in coronary angiography due to its easy accessibility and high success rate. Various techniques exist for achieving hemostasis following femoral artery catheterization. Objectives The aim of our study is to compare the methods of chitosan-containing hemostatic pad (HP) and manual compression (MC) in terms of efficacy and safety in patients undergoing percutaneous coronary intervention (PCI) with coronary angiography via femoral access. Method A total of 204 patients from 3 centers were included […]

Abstract Background: Ischemic heart disease is one of the most common causes of death worldwide. There are few data in the literature about the association of clinical profile and coronary angiography results in the Brazilian population. Objectives: To assess clinical variables and their associations with the results of coronary angiography and to evaluate the safety of coronary angiography in a public university hospital. Methods: From August 2015 to April 2018, 1 844 patients submitted to coronary angiography at the Pedro […]

Myocardial Infarction with non-Obstructive Coronary Arteries (MINOCA) is the final diagnosis in 6-10% of all acute coronary syndromes (ACS). It is mostly present in female individuals. MINOCA was defined by the European Society of Cardiology (ESC) in 2017, and the Fourth Universal Definition of Myocardial Infarction (2018) further reinforced this concept. , Dreyer et al., analyzing Medicare data in the United States, determined an incidence for MINOCA of 5.9%. Lower rates of one-year MACE (1.7% vs 27.6%), mortality (12.3% vs […]

Abstract Background Some of the patients admitted for acute myocardial infarction have non-obstructive coronary artery disease (MINOCA). Their prognosis is not always benign, making it necessary the development of tools for risk stratification of these patients. Objectives To describe the characteristics of a sample of patients admitted for suspected MINOCA and to evaluate the prognostic value of GRACE score in this population. Methods This was a retrospective, observational, single-center, cohort study involving 56 consecutive patients with MINOCA. During one-year follow-up, […]

Abstract Background Comparative data on the performance of cardiovascular risk scoring systems (CRSSs) in patients with severe coronary artery disease (CAD) are lacking. Objectives To compare different CRSSs regarding their ability to discriminate patients with severe CAD. Method A total of 414 patients (297 men; 61.3±12.3 years of age) undergoing coronary angiography were enrolled and evaluated for major risk factors. Cardiovascular risk and risk category were defined for each patient using the Framingham, Systemic Coronary Risk Evaluation (SCORE), and Pooled […]

Introduction Left main coronary artery (LMCA) disease is a high-risk clinical situation, since this artery is responsible for the irrigation of more than two-thirds of the myocardial tissue, LMCA disease is associated with increased risk of adverse cardiac events. Traditionally, the gold standard of treatment for significant LMCA disase, understood as a stenosis> 50%, is coronary artery bypass grafting (CABG) surgery. – The technological evolution of percutaneous treatment and its safe application for LMCA disease in the PRECOMBAT study made […]

Abstract Background: By observing the high prevalence of failures in the surgical treatment of myocardial revascularization (MR), with the use of the Left Internal Thoracic Artery (LITA) as a graft, evidenced by the international literature, it was sought to demonstrate the prevalence of lesions that would not allow the use of LITA as a graft in myocardial revascularization surgery, with possible alteration in the surgical management performed by the cardiac surgeon, and reduction of the morbimortality of these patients. Objectives: […]
