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.

Clinical TrialRisk assessment and comparative effectiveness of left ventricular assist device and medical management in ambulatory heart failure patients: design and rationale of the ROADMAP clinical trial.
Mechanical circulatory support is now a proven therapy for the treatment of patients with advanced heart failure and cardiogenic shock. The role for this therapy in patients with less severe heart failure is unknown. ⋯ This trial will be the first prospective clinical evaluation comparing outcomes of patients with advanced ambulatory heart failure treated with either ongoing medical therapy or a left ventricular assist device. It is anticipated to provide novel insights regarding relative outcomes with each treatment and an understanding of patient and provider acceptance of the ventricular assist device therapy. This trial will also provide information regarding the risk of events in "stable" patients with advanced heart failure and guidance for the optimal timing of left ventricular assist device therapy.
