Table 5. Kaplan-Meier estimates, unadjusted & PS-stratified hazard ratios, stratified by clopidogrel or ticagrelor prescribed at discharge.
Outcome | Ticagrelor (n=1,717) | Clopidogrel (n=8,648) | Unadjusted hazard ratio (95% CI) | p-value | PS-stratified hazard ratio* | p-value |
---|---|---|---|---|---|---|
Death or MI | 47 (3.1%) | 223 (3.1%) | 1.03 (0.75-1.41) | 0.849 | 0.96 (0.68-1.38) | 0.844 |
Death | 16 (1.1%) | 108 (1.5%) | 0.72 (0.43-1.22) | 0.221 | 0.60 (0.31-1.17) | 0.132 |
Myocardial infarction | 27 (1.8%) | 104 (1.4%) | 1.27 (0.83-1.94) | 0.267 | 1.25 (0.78 - 1.98) | 0.354 |
* Propensity score was generated using the following variables: age2, age, gender, BMI (kg/m2), current smoking status, hypertension, hyperlipidaemia, cerebrovascular disease, prior MI, prior CABG, LVEF, acute coronary syndrome, calcification-moderate/severe, chronic total occlusion, and complex PCI. MI: myocardial infarction; PS: propensity score |
