Observational Study
Preoperative Use of Intra-Aortic Balloon Pump Support Reduced 30-Day Mortality in a Population with LVEF >35% and High Surgical Risk after Coronary Artery Bypass Graft Surgery.
The intra-aortic balloon pump (IABP) is used to prevent complications after coronary artery bypass grafting (CABG) surgery, although some results are controversial and basal ventricular function may play a role. This study assessed the benefit of preoperative use of IABP, as stratified by the ventricular function, in a population submitted to high-surgical-risk CABG. ⋯ The preoperative use of IABP was associated with an independent reduction of 30-day mortality risk in cases with LVEF >35% in a population submitted to high-surgical-risk CABG. Likewise, the use of IABP was associated with a lower risk of postoperative renal complications.

Statins are recommended for secondary prevention. Our aims were to describe the proportion of very elderly patients receiving statins after non-ST segment elevation acute coronary syndrome (NST-ACS) and to determine the prognostic implications of statins use. ⋯ Although most octogenarians presenting a NST-ACS are already on statins before the episode, their LDL cholesterol is frequently >2.6 mmol/L. Octogenarians who do not receive statins have a high-risk profile, with significant frailty and comorbidity.

Non-ST elevation myocardial infarction (NSTEMI) is one of the most common manifestations of acute coronary syndromes (ACS). We evaluated the prognostic role of cardiac troponin I (cTnI) at presentation and peak cardiac troponin I in patients with NSTEMI. ⋯ These findings documented the different prognostic significance of cTnI at presentation and peak cTnI in patients presenting with NSTEMI, and highlighted the importance of monitoring the levels of cTnI in this high-risk population.
