Predictors of myocardial contractile recovery after coronary revascularization in patients with prior myocardial infarction.
We sought to explore the prognostic power of certain patient characteristics to predict myocardial contractile recovery after coronary revascularization in patients with prior myocardial infarction. ⋯ In patients with prior myocardial infarction, the presence of Grade 2-3 collaterals to the infarct-related artery and the shorter age of infarction at the time of revascularization independently predicted myocardial contractile recovery after coronary revascularization.

Randomized Controlled TrialHyperbaric oxygen preconditioning improves myocardial function, reduces length of intensive care stay, and limits complications post coronary artery bypass graft surgery.
The objective of this study was to determine whether preconditioning coronary artery disease (CAD) patients with HBO(2) prior to first-time elective on-pump cardiopulmonary bypass (CPB) coronary artery bypass graft surgery (CABG) leads to improved myocardial left ventricular stroke work (LVSW) post CABG. The primary end point of this study was to demonstrate that preconditioning CAD patients with HBO(2) prior to on-pump CPB CABG leads to a statistically significant (P<.05) improvement in myocardial LVSW 24 h post CABG. ⋯ This study met its primary end point and demonstrated that preconditioning CAD patients with HBO(2) prior to on-pump CPB CABG was capable of improving LVSW. Additionally, this study also showed that HBO(2) preconditioning prior to CABG reduced myocardial injury, intraoperative blood loss, ICU length of stay, postoperative complications, and saved on cost, post CABG.

Case ReportsClosure of a coexisting ostium secundum atrial septal defect and patent foramen ovale using a single Amplatzer patent foramen ovale occluder device.
We report the case of a 59-year-old man with cryptogenic stroke who was found to have both an ostium secundum atrial septal defect and a patent foramen ovale (PFO) by intracardiac echocardiography. Both defects were successfully occluded using a single 35-mm Amplatzer PFO occluder device inserted through the atrial septal defect.
