Comparative StudyRisk factors and outcome of new-onset cardiac arrhythmias in vascular surgery patients.
The pathophysiology of new-onset cardiac arrhythmias is complex and may bring about severe cardiovascular complications. The relevance of perioperative arrhythmias during vascular surgery has not been investigated. The aim of this study was to assess risk factors and prognosis of new-onset arrhythmias during vascular surgery. ⋯ New-onset perioperative arrhythmias are common after vascular surgery. The elderly and patients with reduced LVF show arrhythmias. Perioperative continuous ECG monitoring helps to identify this high-risk group at increased risk of cardiovascular events and death.

Comparative StudyEarly ST-segment recovery after primary percutaneous coronary intervention accurately predicts long-term prognosis after acute myocardial infarction.
Several ancillary studies reported on the prognostic value of ST-segment recovery (STR) with measurement at 30 to 240 minutes after primary percutaneous coronary intervention (PCI). We determined the long-term prognostic value of early STR, assessed at the end of primary PCI, in unselected patients after ST-segment elevation myocardial infarction (STEMI). ⋯ Early STR assessment has strong, long-term prognostic properties in all-comer STEMI patients. Moreover, the prognostic power of early STR is not restricted to the early recovery phase after STEMI, but identifies high-risk subgroups among 1-year survivors.

Comparative StudyIatrogenic left main coronary artery dissection: incidence, classification, management, and long-term follow-up.
Although rare, iatrogenic left main coronary artery (LM) dissection is a feared complication of coronary catheterization. Its incidence, optimal therapeutic management, and prognosis remain largely unknown. The aim of the present study was to estimate the incidence, characterize the population at risk, depict the initial management, and evaluate the long-term prognosis of iatrogenic LM dissection. ⋯ Iatrogenic LM dissection is a rare complication of cardiac catheterization procedures with favorable early and long-term outcome when recognized timely and managed properly.
