Table 1 Definition of study groups
Group | Target Time for Surgery | Anginal Symptoms, Coronary Anatomy, and Left Ventricular Function |
|---|---|---|
Semi-urgent | Within 6 weeks | Patients with either persistent unstable angina or stable angina and extensive CAD* (left-main stenosis more than 50 percent, triple-vessel disease, or double-vessel disease with significant proximal left anterior descending stenosis and impaired left ventricular function) |
Non-urgent | Within 12 weeks | Stable symptomatic patients with limited CAD (double-vessel disease with no lesion in the proximal left anterior descending artery and normal left ventricular function or single-vessel disease with significant stenosis of the proximal left anterior descending artery) |
