Performance of ChatGPT in the Portuguese National Residency Access Examination

ChatGPT, a language model developed by OpenAI, has been tested in several medical board examinations. This study aims to evaluate the performance of ChatGPT on the Portuguese National Residency Access Examination, a mandatory test for medical residency in Portugal. The study specifically compares the capabilities of ChatGPT versions 3.5 and 4o across five examination editions from 2019 to 2023. A total of 750 m...

Aortic Root Honeycomb: A Rare Cardiac Surgery Complication

Cardiovascular Risk Assessment after COVID-19 Infection before Resuming Sports ...

Background: The risk of sports-related sudden cardiac arrest after COVID-19 infection can be a serious problem. There is an urgent need for evidence-based criteria to ensure patient safety before resuming exercise. Objective: To estimate the pooled prevalence of acute myocardial injury caused by COVID-19 and to provide an easy-to-use cardiovascular risk assessment toolkit prior to resuming sports activities aft...

Left atrial functional assessment and mortality in patients with severe aortic ...

Aortic valve stenosis (AS) is the most common primary valvular heart disease leading to surgical or percutaneous aortic valve replacement (AVR) in Europe and its prevalence keeps growing. While other risk factors in severe AS are well documented, little is known about the prognostic value of left atrial (LA) function in AS. Our aim is to clarify the relationship between LA function measured at severe AS diagnos...

Global longitudinal strain in chronic asymptomatic aortic regurgitation: system...

Chronic aortic regurgitation (AR) patients typically remain asymptomatic for a long time. Left ventricular mechanics, namely global longitudinal strain (GLS), has been associated with outcomes in AR patients. The authors conducted a systematic review to summarize and appraise GLS impact on mortality, the need for aortic valve replacement (AVR) and disease progression in AR patients. A literature search was perf...

Glycoprotein IIb/IIIa inhibitors for cardiogenic shock complicating acute myoca...

Background: Cardiogenic shock complicates 5–10% of myocardial infarction (MI) cases. Data about the benefit of glycoprotein IIb/IIIa inhibitors (GPI) in these patients is sparse and conflicting. Methods: We performed a systematic review, meta-analysis, and meta-regression of studies assessing the impact of GPI use in the setting of MI complicated cardiogenic shock on mortality, angiographic success, and bleedin...

COVID-19 and cardiovascular comorbidities: An update

Going beyond classic echo in aortic stenosis: left atrial mechanics, a new mark...

Background: There is limited information regarding left atrial (LA) mechanics in aortic valve stenosis (AS). We assessed LA mechanics in AS through speckle-tracking echocardiography (STE) according to severity and prognosis. Methods: We included 102 patients diagnosed with severe AS (sAS) and 80 patients with moderate AS (mAS), all with preserved ejection fraction and no coronary artery disease. LA mechanics an...

Three-dimensional speckle tracking echocardiography: The future is now

Remodelagem cardíaca induzida pelo exercício físico em atletas de nível competi...

Introdução: A remodelagem cardíaca induzida pelo exercício físico é frequente em atletas. Esta adaptac¸ão manifesta-se a nível estrutural com o aumento das dimensões e massa cardíacas. Os militares também são sujeitos a exercício físico intenso, com especificidades distintas. Objetivo: Comparar a remodelagem cardíaca induzida pelo exercício físico em atletas de competic¸ão e pelo treino militar em militares a f...
