Results of a Prospective Study to Evaluate the Impact of Point-of-Care Ultrasound in the Enhancement of Gastrointestinal Bleeding Risk Scores.

Objectives: Gastrointestinal (GI) bleeding is a common illness seen in the emergency department. The prognosis varies from self-limited to potentially life threatening. Currently available GI bleeding risk scores have only a modest predictive value, limiting their wide implementation.

Inspiratory collapse of the inferior vena cava and the kissing ventricle sign: markers of poor prognosis in emergency gastrointestinal bleeding.

Objectives: Gastrointestinal bleeding, one of the main reasons for emergency department visits, is associated with significant mortality, complications, and high health care spending. Studies have shown the usefulness of hemodynamic monitoring by ultrasound of the inferior vena cava (IVC), imaging of systolic obstruction of the left ventricle (the kissing sign), changes in cardiac output, or surrogates for cardiac output such as the left ventricular velocity time integral before and after a passive leg raise. There is currently no evidence for applying this approach to evaluating hypovolemia due to gastrointestinal bleeding.

Characteristics of patients with myocardial infarction with nonobstructive coronary arteries (MINOCA) from the ARIAM-SEMICYUC registry: development of a score for predicting MINOCA.

Background: Acute myocardial infarction (AMI) with no evidence of relevant stenosis of the coronary artery, known as myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA), has a prevalence of up to 14%. The various causes of MINOCA lead to damage of the myocardium, and there are marked differences in diagnoses, prognoses, and treatments. Although the number of patients affected is considerable owing to the high prevalence of acute coronary syndrome (ACS), the causes of MINOCA have received little attention with the result that some patients may not receive appropriate treatment.

[Influence of the combination of antiplatelet agents on the occurrence of early left ventricular insufficiency in patients with acute coronary syndromes without persistent ST-segment elevation].

Background And Objective: The frequency of left ventricular failure (LVF) in the early stages of non-ST-segment elevation acute coronary syndrome (NSTE ACS) has not been described so far. The objective of this study is to describe for the first time the frequency of LVF in the early course of NSTE ACS and to assess its association with other interventions.

Patients And Method: Observational prospective cohort multicenter study in intensive and coronary care units (ICCU).
