Brief Summary:

The TReatment with ADP receptor iNhibitorS: Longitudinal Assessment of Treatment Patterns and Events after Acute Coronary Syndrome (TRANSLATE-ACS) study is a prospective, observational longitudinal study to evaluate the real world effectiveness and use of prasugrel and other ADP receptor inhibitor therapies among myocardial infarction (MI) participants treated with percutaneous coronary intervention (PCI) during the index hospitalization. Participant management and treatment decisions are at the discretion of the care team per routine clinical practice. Approximately 17,000 participants will be enrolled at approximately 350 sites in the United States. Follow-up will be conducted through 15 months in approximately 15,650 participants.

TRANSLATE-ACS will complement the results of both randomized controlled clinical trials and current registries in addressing the real world treatment patterns and clinical outcomes for MI participants managed with PCI and initiated on ADP receptor inhibitor therapy. In addition to determining the effectiveness of prasugrel in comparison to other ADP receptor inhibitors, the study will also determine factors associated with initial ADP receptor inhibitor selection and longitudinal patterns of use, evaluate the safety, and describe and compare resource use and medical costs associated with ADP receptor inhibitors. Additionally, this study will generate a continuum of information from the inpatient to outpatient settings to provide a comprehensive picture of participant treatment and outcomes not currently available for novel ADP receptor inhibitors.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of Participants With Major Adverse Cardiovascular Events (MACE) [ Time Frame: Baseline through 12 months ]
    MACE is defined as a composite of all-cause death, myocardial infarction (MI), stroke, or unplanned coronary revascularization. Events that occurred more than 7 days after medication was switched or discontinued were excluded from the analysis. Observed (unadjusted) percentages of participants with MACE, as well as the statistical analyses adjusted for baseline cohort differences, are presented. Percentage of participants = (number of participants with events in 12 months/ number of participants treated) * 100.

  2. Factors Associated With Initial Adenosine Diphosphate (ADP) Receptor Inhibitor Selection at Enrollment [ Time Frame: Day 0 (study enrollment) ]
    Factors are drug-eluting stent (DES) vs. bare metal stent (BMS) placement, other (no stent) vs. BMS, STEMI, other race, cardiogenic shock occurred within 24 hours, male, European Quality of Life Questionnaire-5 Dimension Health State Score (EQ-5D) - United States (US) Index =1 vs. <1, married, diabetes, and other vs. BMS placement. The EQ-5D US index is a participant-rated, health-related, quality-of-life instrument based on US population. Scores range from -0.11 to 1.0 with 1.0 = perfect health.

  3. Factors Associated With Initial ADP Receptor Inhibitor Selection at Enrollment: Pre-Procedure Hemoglobin [ Time Frame: Day 0 (study enrollment) ]
  4. Factors Associated With Initial ADP Receptor Inhibitor Selection at Enrollment: Duke Coronary Artery Disease (CAD) Index [ Time Frame: Day 0 (study enrollment) ]
    The Duke CAD Index is a validated composite measure of angiographic burden, which assigns prognostic weights 1 through 100. Higher scores indicate greater angiographic burden and are associated with poorer prognosis.


Secondary Outcome Measures :
  1. Percentage of Participants With Cumulative Severe or Moderate Bleeding Events [ Time Frame: Baseline, 1, 6, 12 and 15 months ]
    Bleeding events were collected utilizing the Global Utilization of Streptokinase and Tissue Plasminogen Activator for Occluded Coronary Arteries (GUSTO) definition of bleeding. Non-coronary artery bypass grafting (CABG)-related GUSTO severe or life-threatening bleeding is any intracranial hemorrhage (ICH) OR any bleeding event resulting in substantial hemodynamic compromise requiring treatment. Non-CABG-related GUSTO moderate bleeding is any bleeding event resulting in the need for transfusion that is not considered a GUSTO severe or life-threatening bleed. Additional bleeding events are fatal bleeding or ICH, or any non -fatal surgical-related bleeding events leading to ≥4 units of red cell transfusion. Observed (unadjusted) percentages of participants with bleeding events, as well as the statistical analyses adjusted for baseline cohort differences, are presented. Percentage of participants = (number of participants with events / number of participants treated) * 100.

  2. Percentage of Participants With MACE and Who Had No Prior History of Transient Ischemic Attack (TIA)/Stroke, Weigh ≥60 Kilograms (kg), and Are Age <75 Years [ Time Frame: Baseline through 12 months ]
    MACE is defined as a composite of all-cause death, MI, stroke, or unplanned coronary revascularization. Events that occurred more than 7 days after medication was switched or discontinued were excluded from the analysis. Observed (unadjusted) percentages of participants with MACE, as well as the statistical analyses adjusted for baseline cohort differences, are presented. Percentage of participant = (number of participants with events / number of participants treated) * 100.

  3. Percentage of Participants With MACE Over 1, 6 and 15 Months [ Time Frame: Baseline through 1, 6 and 15 months ]
    MACE is defined as a composite of all-cause death, MI, stroke, or unplanned coronary revascularization. Events that occurred more than 7 days after medication was switched or discontinued were excluded from the analysis. Observed (unadjusted) percentages of participants with MACE are presented. Kaplan-Meier analysis was used to estimate the percentage of participants with a MACE event.

  4. Percentage of Participants With Definite or Probable Stent Thrombosis (ST) Events [ Time Frame: Baseline through 15 months ]
    Academic Research Consortium (ARC) criteria were used to define ST. Definite ST is angiographic or pathologic confirmation of partial or total thrombotic occlusion within the peri-stent region, and at least 1 of the following additional criteria: acute ischemic symptoms; ischemic electrocardiogram changes; elevated cardiac biomarkers. Probable ST is any unexplained death within 30 days of stent implantation; any MI, which is related to documented acute ischemia in the territory of the implanted stent without angiographic confirmation of ST and in the absence of any other obvious cause. Events that occurred more than 7 days after medication was switched or discontinued were excluded from the analysis. Observed (unadjusted) percentages of participants with ST events are presented. Kaplan-Meier analysis was used to estimate the percentage of participants with a definite or probable ST event.

  5. Resource Use Patterns, Cumulative Total Medical Costs, and Cost Effectiveness [ Time Frame: 15 months ]
