Abstract Approximately 300 million non-cardiac surgeries are performed annually worldwide and adverse cardiovascular events are the main cause of morbidity and mortality in the peri- and postoperative period. Myocardial injury after non-cardiac surgery (MINS) is a new clinical entity associated with adverse cardiovascular outcomes. MINS is defined as myocardial injury that can result in necrosis due to ischemia, marked by increase in biomarker levels. It has prognostic relevance and occurs within up to 30 days after non-cardiac surgery. The diagnostic […]

Abstract Background: Although maximal and submaximal walking are recommended for patients with peripheral artery disease (PAD), performing these exercises may induce different physiological responses. Objectives: To compare the acute effects of maximal and submaximal walking on post-exercise cardiovascular function, regulation, and associated pathophysiological processes in patients with symptomatic PAD. Methods: Thirty male patients underwent 2 sessions: maximal walking (Gardner’s protocol) and submaximal walking (15 bouts of 2 minutes of walking separated by 2 minutes of upright rest). In each session, […]

Abstract Background The novel coronavirus disease (COVID-19) may lead to severe disease that can cause death. COVID-19 is known to affect the cardiovascular system. Early detection of the progression to the severe disease stage that affects the cardiovascular system may play a critical role in the treatment of COVID-19. Objectives To explore the possible relationship between the COVID-19 pneumonia and right ventricular strain findings on electrocardiography (ECG). Methods We conducted a retrospective study of 141 hospitalized patients with COVID-19. Spearman’s […]

Abstract Background COVID-19 pandemic represents a huge burden to the health system in the world. Although pediatric COVID-19 patients have been relatively spared compared with adults, recent reports showed an increasing number of critically ill patients with multisystemic inflammatory syndrome in children (MIS-c), with marked cardiovascular impairment. Nevertheless, little is known about the relationship between cardiac abnormalities and inflammatory and coagulation biomarkers. Objectives to investigate echocardiographic abnormalities in pediatric patients with COVID-19 admitted to tertiary hospital. Methods this was a […]

Abstract Background: In patients with acute myocardial infarction (MI), cardiogenic shock (CS), and multivessel disease (MVD) questions remain unanswered when it comes to intervention on non-culprit arteries. Objective: This article aims to 1) characterize patients with MI, CS and MVD included in the Portuguese Registry on Acute Coronary Syndromes (ProACS); 2) compare different revascularization strategies in the sample; 3) identify predictors of in-hospital mortality among these patients. Methods: Observational retrospective study of patients with MI, CS and MVD included in […]

Dear Editor, We would like to share ideas on the publication “Prognostic Value of Troponin-T and B-Type Natriuretic Peptide in Patients Hospitalized for COVID-19 [1].” Almeida Jr. et al. reported using Memory box as a tool to support grief and concluded that “In the first 24h of admission, TnT, but not BNP, was an independent marker of mortality or need for invasive mechanical ventilation.” In COVID-19, cardiac complication is possible and is common in severe infection. Myocardial involvement is a […]

Abstract Background: It is suggested that serglycin has important functions in fibrin stabilization and inflammation but there is limited information on its clinical value for atherosclerotic heart disease. Objective: The purpose of this study is to find out serum serglycin levels in acute myocardial infarction patients and in the control group individuals; and to investigate the association between serglycin levels with inflammation markers and infarct size markers. Methods: The study population consisted of 75 patients with ST-segment elevation myocardial infarction […]
