The relative benefit of staged percutaneous coronary intervention (PCI) versus culprit-only PCI in patients with ST-segment elevation myocardial infarction and multivessel coronary disease remains disputable. Therefore, we conducted this study to compare the long-term outcomes of staged complete revascularization and culprit-only PCI in this population. A total of 1,205 patients were treated with staged PCI (n = 576) or culprit-only PCI (n = 629) from January 2006 to December 2015 in our center. ⋯ However, there was no difference in the risks of MACCE, MI and unplanned revascularization between the 2 approaches for diabetic patients. In conclusion, among patients with ST-segment elevation myocardial infarction and multivessel disease who underwent primary PCI, an approach of staged complete revascularization is superior to culprit-only PCI at 5-year follow-up. Nevertheless, the advantage of staged PCI is attenuated in diabetic patients.

Readmissions Following Isolated Coronary Artery Bypass Graft Surgery in the United States (from the Nationwide Readmissions Database 2010 to 2014).
Readmission following cardiac surgery is associated with poor outcomes and increased healthcare expenditure. However, a nationwide understanding of the incidence, cost, causes, and predictors of 30-day readmission following coronary artery bypass grafting is limited. The Nationwide Readmissions Database was used to identify all adult patients who underwent isolated coronary artery bypass grafting (CABG) with no other concomitant surgery between 2010 and 2014. ⋯ CABG performed at a high CABG volume hospital was protective of readmission (OR 0.95; 95% CI 0.91 to 0.99). In conclusion, we characterized using a national sample the incidence, causes, costs, and predictors of 30-day readmission following CABG. Targeting modifiable risk factors for readmission should be a priority to reduce rates of readmission and decrease healthcare expenditure.

Relation of Isolated Systolic Hypertension and Pulse Pressure to High-Sensitivity Cardiac Troponin-T and N-Terminal pro-B-Type Natriuretic Peptide in Older Adults (from the Atherosclerosis Risk in Communities Study).
Isolated systolic hypertension (ISH) and elevated pulse pressure (PP) are common blood pressure (BP) abnormalities in older adults, reflect poor vascular compliance, and can signify risk for cardiovascular outcomes. We sought to characterize the associations of ISH and widened PP with high-sensitivity Troponin-T (hs-cTnT; a marker of myocardial damage) and N-terminal pro-B-type natriuretic peptide (NT-proBNP; a marker of hemodynamic stress) levels in older adults. We performed a cross-sectional analysis of 5,251 Atherosclerosis Risk in Communities (ARIC) study participants without heart failure who attended visit 5 (2011 to 2013). ⋯ Increasing quartiles of PP were also significantly associated with both elevated hs-cTnT (p-for-trend <0.0001) and NT-proBNP (p-for-trend <0.0001). These associations were not modified by BP treatment status. In conclusion, ISH and wide PP are relatively common in older adults despite contemporary BP treatment and are associated with abnormalities in hs-cTnT and NT-pro BNP, findings that could guide personalized treatment of older patients with these BP aberrations.

Wild-type transthyretin amyloidosis (ATTRwt) results in an infiltrative cardiomyopathy often culminating in symptomatic heart failure. The use of cardiopulmonary exercise testing (CPET) in determining outcomes in ATTRwt cardiac amyloidosis is unknown. Given the emergence of novel therapies to treat transthyretin amyloidosis, we sought to investigate the utility of CPET on outcomes in patients with ATTRwt cardiomyopathy. ⋯ Receiver-operating characteristic curve showed that the combination of VE/VCO2, CRP, sodium, and creatinine (Area under the ROC Curve [AUC], 0.89) predicted 1-year mortality in ATTRwt cardiac amyloidosis. In conclusion, increased VE/VCO2, in combination with CRP, sodium, and creatinine, may identify patients at increased risk of death in ATTRwt cardiomyopathy. VE/VCO2 might have a role in objectively assessing therapeutic response in ATTRwt cardiac amyloidosis.

Propensity Matched Analysis Comparing Conscious Sedation Versus General Anesthesia in Transcatheter Aortic Valve Implantation.
Conscious sedation (CS) has been increasingly utilized in transcatheter aortic valve implantation (TAVI). We aim to compare safety, efficacy, efficiency, and direct cost outcomes of patients who underwent TAVI with general anesthesia (GA) to those with CS. Records for all adult patients undergoing transfemoral TAVI at our institution between February 2012 and September 2018 were retrospectively screened. ⋯ Total direct costs for CS were decreased in almost every departmental category, with a mean 10.4% reduction in overall direct costs (p < 0.001). In conclusion, TAVI with CS is associated with less bleeding and vascular events, lower procedural radiation exposure, reduced length of hospitalization and ICU stay, and lower direct costs in comparison with TAVI with GA. These outcomes occur without sacrificing procedural efficacy or safety.
