Deep sedation for gastrointestinal endoscopy in elderly patients. Subgroup analysis.

Background: Gastrointestinal endoscopy is increasingly performed under sedation in older patients. Aging has implications in increasing the morbidity and the risk of complications related to sedation. The aim of this study is to assess the difference in complications between patients aged 65 to 74 years and those aged over 75 years.

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.
