Multicenter Study Comparative StudyImproving the process of informed consent for percutaneous coronary intervention: patient outcomes from the Patient Risk Information Services Manager (ePRISM) study.
While the process of informed consent is designed to transfer knowledge of the risks and benefits of treatment and to engage patients in shared medical decision-making, this is poorly done in routine clinical care. We assessed the impact of a novel informed consent form for percutaneous coronary intervention (PCI) that is more simply written, includes images of the procedure, and embeds individualized estimates of outcomes on multiple domains of successful informed consent and shared decision-making. ⋯ A personalized consent document improved the process of informed consent and shared decision-making. Marked heterogeneity across hospitals highlights that consent documents are but one aspect of engaging patients in understanding and participating in treatment.

Randomized Controlled Trial Multicenter StudyCardiac troponin I for prediction of clinical outcomes and cardiac function through 3-month follow-up after primary percutaneous coronary intervention for ST-segment elevation myocardial infarction.
Circulating levels of cardiac troponin I (cTnI) after ST-segment elevation myocardial infarction (STEMI) are associated with infarct size and chronic left ventricular dysfunction, but the relation to clinical end points and biochemical measures of global cardiac function remains less well defined. ⋯ Cardiac troponin I measured after primary PCI for STEMI is independently associated with clinical outcomes and cardiac function through 3-month follow-up. These results suggest that cTnI levels are a useful risk stratification tool in STEMI patients.

Randomized Controlled TrialPredictors and impact of target vessel revascularization after stent implantation for acute ST-segment elevation myocardial infarction: lessons from HORIZONS-AMI.
Target vessel revascularization (TVR) may compromise the benefits of primary percutaneous coronary intervention in ST-segment elevation myocardial infarction (STEMI) We set out to identify the predictors and examine the impact of TVR after STEMI in patients receiving a coronary stent. ⋯ In HORIZONS-AMI, TVR within 3 years after stent implantation was performed in ~1 of every 7 patients and was associated with more extensive coronary disease, more complex procedures, and bare metal stents. Target vessel revascularization was often due to stent thrombosis and disease progression as well as restenosis and was strongly associated with adverse outcomes but not mortality.

Randomized Controlled Trial Comparative StudyTargeted versus standard feedback: results from a randomized quality improvement trial.
Quality improvement is central to improving the care of patients with cardiovascular disease; however, the optimum type of data feedback to support such efforts is unknown. ⋯ We were unable to demonstrate that targeted performance feedback reports lead to more rapid care improvements than standard reports. Future directions should explore the relationship between hospital self-selection of targeted metrics and the identification and promulgation of less common metrics--particularly those that reflect processes of care.

Impact of drug-eluting stents on the comparative effectiveness of coronary artery bypass surgery and percutaneous coronary intervention.
Drug-eluting stents (DES) have largely replaced bare-metal stents (BMS) for percutaneous coronary intervention (PCI). It is uncertain, however, whether introduction of DES had a significant impact on the comparative effectiveness of PCI versus coronary artery bypass graft surgery (CABG) for death and myocardial infarction (MI). ⋯ The introduction of DES did not alter the comparative effectiveness of CABG and PCI with respect to hard cardiac outcomes.
