Left main and/or three-vessel disease in patients with non-ST-segment elevation myocardial infarction and low-risk GRACE score: Prevalence, clinical outcomes and predictors.

Introduction: A low-risk GRACE score identifies patients with a lower incidence of major cardiac events, however it can erroneously classify patients with severe coronary artery disease as low-risk. We assessed the prevalence, clinical outcomes and predictors of left main and/or three-vessel disease (LM/3VD) in non-ST-elevation acute myocardial infarction (NSTEMI) patients with a GRACE score of ≤108 at admission.

Methods: Using data from the Portuguese Registry on Acute Coronary Syndromes, 1196 patients with NSTEMI and a GRACE score of ≤108 who underwent coronary angiography were studied.

Acute kidney injury in acute coronary syndromes - An important multifactorial consequence.

Introduction: Acute kidney injury (AKI) is a pathological phenomenon with a negative impact on outcomes in different clinical scenarios. Its mechanism in acute coronary syndrome (ACS) is not completely understood, and measures to prevent it are not uniform. We set out to study the incidence, clinical relevance, predictors and possible implications for patient management of AKI in ACS.

Fulminant myocarditis caused by Legionella pneumophila: case report.

Myocarditis is defined as inflammation of the myocardium. The clinical manifestations of myocarditis vary from flu-like symptoms to fatal fulminant forms. We report the case of a 39-year-old woman with a diagnosis of cardiogenic shock caused by fulminant myocarditis.
