Treatment With Adenosine Diphosphate (ADP) Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome

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.

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.

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.

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.

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.

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.

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.
