Concerns regarding the use of selected bone marrow stem cells (BMSCs) in the field of cardiac repair after acute ischemic events have been raised. The current meta-analysis aimed to assess the efficacy and safety of selected BMSC transplantation in patients with acute myocardial infarction (AMI) based on published randomized controlled trials (RCTs). ⋯ Transplantation of selected BMSCs for patients with AMI is safe and induces a significant increase in LVEF with a limited impact on left ventricular remodeling.

This study aimed to compare the accuracy of ECG interpretation for diagnosis of STEMI by different groups of healthcare professionals involved in the STEMI program at our institution. ⋯ Our study showed that healthcare profession and number of ECGs reviewed per week are predictive of the accuracy of ECG interpretation of STEMI. Cardiologists are the most accurate diagnosticians, and are the least likely to falsely activate the CCL. Weekly exposure of ≥ 20 ECGs may improve diagnostic accuracy regardless of underlying experience.

To assess the prognostic relevance of cardiac troponin T (cTnT) values and their serial changes as measured with a high-sensitivity assay in acute ischaemic stroke. ⋯ Our study adds novel findings relevant for interpretation of highly sensitive cTnT assays in acute ischaemic stroke: a) Myocardial injury is detectable in more than half of patients; b) even moderately elevated cTnT is associated with unfavourable outcome (optimal cut-off 16 ng/l); and c) dynamic changes in cTnT indicate an increased risk of in-hospital death.
