Abstract Background Several studies have shown that women are usually undertreated and have worse outcomes after ST-segment elevation myocardial infarction (STEMI), hence the need to investigate questions related to sex in Brazil to better deal with the problem. Objective To determine whether female sex is still associated with adverse events in a contemporary cohort of patients with STEMI undergoing primary percutaneous coronary intervention (pPCI). Methods This was a prospective cohort study of STEMI patients submitted to pPCI in a tertiary […]

Abstract Background: There is limited data on the prognostic value of stress cardiac magnetic resonance (CMR) in older adults. Objective: To determine the prognostic value of adenosine stress CMR in older individuals with known or suspected coronary artery disease (CAD). Methods: Between 2010 and 2015, consecutive patients aged 65 years or older referred for adenosine stress CMR were followed for the occurrence of severe cardiac events (cardiac death and nonfatal myocardial infarction) and major adverse cardiovascular events (MACE) that also […]

Abstract Background Aortic stiffness is established as a marker of cardiovascular disease. Cardiovascular magnetic resonance (CMR) provides a comprehensive assessment of aortic stiffness and myocardial ischemia in a single examination. However, prognostic data concerning aortic stiffness in elderly patients remain limited. Objective To determine the prognostic value of aortic stiffness using CMR-based pulse wave velocity (PWV) in elderly patients with known or suspected coronary artery disease (CAD). Methods This study enrolled consecutive patients aged >70 referred for adenosine stress perfusion […]

Abstract Background According to traditional diagnosis thinking, very elderly individuals are more predisposed to develop atypical symptoms in acute coronary syndromes. Objective To test the hypothesis that very elderly individuals are more predisposed to atypical chest pain manifestations due to obstructive coronary artery disease (CAD). Methods The Registry of Thoracic Pain includes patients admitted with acute chest pain. Firstly, the typicality index of this clinical manifestation was constructed: the sum of 12 symptom characteristics (8 typical and 4 atypical symptoms). […]
