Oral anticoagulation and antiplatelets in atrial fibrillation patients after myocardial infarction and coronary intervention.
The purpose of this study was to investigate the risk of thrombosis and bleeding according to multiple antithrombotic treatment regimens in atrial fibrillation (AF) patients after myocardial infarction (MI) or percutaneous coronary intervention (PCI). ⋯ In real-life AF patients with indication for multiple antithrombotic drugs after MI/PCI, OAC and clopidogrel was equal or better on both benefit and safety outcomes compared to triple therapy.

Right, but not left, bundle branch block is associated with large anteroseptal scar.
This study sought to test the hypothesis that right bundle branch block (RBBB) patients have larger scar size than left bundle branch block (LBBB) patients do. ⋯ In patients with LV ejection fraction ≤35%, RBBB is associated with significantly larger scar size than LBBB is, and occlusion of a proximal LAD septal perforator causes RBBB. In contrast, LBBB is most commonly caused by nonischemic pathologies.
