Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Major adverse cardiac events (MACE) | 5 years | The composite of coronary heart disease death, nonfatal myocardial infarction, hospitalization for unstable angina, or fatal or nonfatal ischemic stroke. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Individual components of MACE | 5 years | Cumulative incidence of the individual components of MACE |
| the change in Seattle Angina Questionnaire (SAQ) summary score | 5 years | The SAQ comprises 5 components namely physical limitation, angina stability, angina frequency, treatment satisfaction, and quality of life; these are then incorporated into the summary score. The higher the score, the better the patient's quality of life and physical function. |
| the change in Seattle Angina Questionnaire (SAQ) score of indivadual scale | 5 years | The SAQ comprises 5 components namely physical limitation, angina stability, angina frequency, treatment satisfaction, and quality of life. The higher the score, the better the patient's quality of life or physical function. |
