Abnormal release of cardiac biomarkers in the presence of myocardial oedema evaluated by cardiac magnetic resonance after uncomplicated revascularization procedures.

Aims: To analyse the association of myocardial oedema (ME), observed as high T2 signal intensity (HT2) in cardiac magnetic resonance imaging, with the release of cardiac biomarkers, ventricular ejection, and clinical outcomes after revascularization.

Methods And Results: Patients with stable coronary artery disease with the indication for revascularization were included. Biomarker levels [troponin I (cTnI) and creatine kinase MB (CK-MB)] and T2-weighted and late gadolinium enhancement (LGE) images were obtained before and after the percutaneous or surgical revascularization procedures.

The safety of SGLT-2 inhibitors in diabetic patients submitted to elective percutaneous coronary intervention regarding kidney function: SAFE-PCI pilot study.

Background: Percutaneous coronary intervention (PCI) is one of the most performed well-succeeded therapeutic procedures worldwide, reducing symptoms and improving quality of life. Neutrophil Gelatinase-associated Lipocalin (NGAL) is a biomarker of acute kidney injury (AKI) produced early after an ischemic renal insult. Osmotic diuresis and the vasoconstriction of the afferent arteriole promoted by Sodium-glucose Cotransporter-2 Inhibitors (SGLT2i) generate a concern regarding the possibility of dehydration and consequent AKI.

Myocardial tissue microstructure with and without stress-induced ischemia assessed by T1 mapping in patients with stable coronary artery disease.

Background: Stress-induced myocardial ischemia seems not to be associated with cardiovascular events. However, its effects on myocardial tissue characteristics remain under debate. Thus, we sought to assess whether documented stress-induced ischemia is associated with changes in myocardial microstructure evaluated by magnetic resonance native T1 map and extracellular volume fraction (ECV).

Long-term analysis of ventricular function in patients with symptomatic coronary disease who underwent on-pump or off-pump coronary artery bypass grafting.

Background: Systemic deleterious effects of cardiopulmonary bypass have been observed in the postprocedural period. Long-term assessment, including ventricular function (VF), is unclear. The objective of this study was to compare the change of left ventricular ejection fractions (LVEFs) during a long-term follow-up of coronary artery disease (CAD) patients who underwent off-pump (OPCAB) or on-pump coronary artery bypass grafting (ONCAB).

Evaluation of cardiovascular risk biomarkers after moderate consumption of red wine and cachaça in a randomized crossover trial: The Wine and Cachaça Study (WICAS).

Introduction: Moderate daily consumption of alcohol (MDCA) is associated with cardiovascular risk (CVR) reduction in observational studies. Some researches have suggested that this benefit may be associated not only with red wine consumption but also with other beverages. However, there are no clinical trials evaluating the possible CVR benefit of Brazilian spirit (cachaça) in humans.

Cardiovascular events in patients with coronary artery disease with and without myocardial ischemia: Long-term follow-up.

Background: After the results of the ISCHEMIA Trial, the role of myocardial ischemia in the prognosis of coronary artery disease (CAD) was under debate. We sought to comparatively evaluate the long-term prognosis of patients with multivessel CAD with or without documented myocardial ischemia.

Methods: This is a single-center, retrospective, observational cohort study that included patients with CAD obtained from the research protocols database of "The Medicine, Angioplasty or Surgery Study," the MASS Study Group.

Quality improvement program in Latin America decreases mortality after cardiac surgery: a before-after intervention study.

Background: The current challenge of cardiac surgery (CS) is to improve outcomes in adverse scenarios. The aim of this study was to assess the impact of a quality improvement program (QIP) on hospital mortality in the largest CS center in Latin America.

Methods: Patients were divided into two groups: before (Jan 2013-Dec 2015, n = 3534) and after establishment of the QIP (Jan 2017-Dec 2019, n = 3544).

Predictors of outcome in the ISCHEMIA-CKD trial: Anatomy versus ischemia.

Background: The ISCHEMIA-CKD (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches-Chronic Kidney Disease) trial found no advantage to an invasive strategy compared to conservative management in reducing all-cause death or myocardial infarction (D/MI). However, the prognostic influence of angiographic coronary artery disease (CAD) burden and ischemia severity remains unknown in this population. We compared the relative impact of CAD extent and severity of myocardial ischemia on D/MI in patients with advanced chronic kidney disease (CKD).

Most deaths in low-risk cardiac surgery could be avoidable.

It is observed that death rates in cardiac surgery has decreased, however, root causes that behave like triggers of potentially avoidable deaths (AD), especially in low-risk patients (less bias) are often unknown and underexplored, Phase of Care Mortality Analysis (POCMA) can be a valuable tool to identify seminal events (SE), providing valuable information where it is possible to make improvements in the quality and safety of future procedures. Our results show that in São Paul State, only one third of AD in low-risk cardiac surgery was related to specific surgical problems. After a revisited analysis, 75% of deaths could have been avoided, which in the pre-operative phase, the SE was related judgment, patient evaluation and preparation.

COVID-19-associated euglycemic diabetic ketoacidosis in a patient with type 2 diabetes on SGLT2 inhibitor: a case report.

Type 2 diabetes mellitus (DM) patients are at high risk for the development of severe COVID-19. Euglycemic diabetic ketoacidosis (eu-DKA) is a rare life-threatening complication associated with the use of SGLT2 inhibitor that may be unnoticed, particularly in a pandemic setting, due to the absence of significant hyperglycemia, delaying its treatment. In this report, we describe a case of a 56-year-old patient who presented an elevated anion gap metabolic acidosis during a SARS-CoV-2 infection and was diagnosed with SGLT2-associated euglycemic diabetic ketoacidosis.

Pharmacological therapy and cardiovascular risk reduction for type 2 diabetes.

The pharmacological therapy for type 2 diabetes mellitus has presented important advances in recent years, which has impacted the treatment of patients with established cardiovascular disease or with high cardiovascular risk. In this scenario, two drug classes have emerged and demonstrated clear clinical benefits: SGLT-2 inhibitors and GLP-1 agonists. The present review discusses the pharmacology, adverse effects, and clinical trials that have demonstrated the benefits of these medications in reducing cardiovascular risk.

Hypotheses, rationale, design, and methods for prognostic evaluation of a randomized comparison between patients with coronary artery disease associated with ischemic cardiomyopathy who undergo medical or surgical treatment: MASS-VI (HF).

Background: Ischemic cardiomyopathy and severe left ventricular dysfunction are well established to represent the main determinants of poor survival and premature death compared with preserved ventricular function. However, the role of myocardial revascularization as a therapeutic alternative is not known to improve the long-term prognosis in this group of patients. This study will investigate whether myocardial revascularization contributes to a better prognosis for patients compared with those treated with drugs alone and followed over the long term.
