Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. The prevalence of spirometry-verified COPD versus medical-record based COPD in subjects with ACS 2. The adjusted hazard ratio of spirometry-verified COPD for death, reinfarction and stroke in subjects with ACS. Adjustment for age, gender, renal function, C-reactive protein, Killip class, previous myocardial infarction (MI), atrial fibrillation, coronary intervention, secondary preventive medication, diabetes, and smoking history. | — |
Secondary
| Measure | Time frame |
|---|---|
| In subjects with ACS, spirometry-verified COPD is an independent predictor of hospital admissions (due to coronary angiography, percutaneous coronary intervention, coronary artery bypass surgery, angina, heart failure) and length of hospital stay. | — |
