  2. *Mild Coronary Artery disease involvement assumed as Normal.
  3. **Categorization of HEART and SYNTAX scores were done based on the previous definition.
  4. aData of all patients is illustrated by Mean ± SD or Number (%).
  5. bComparison of HEART and SYNTAX scores in different groups were accomplished via One-Way ANOVA and independent T-tests, moreover Pearson correlation coefficient was applied to determine the relationship between these scores and quantitative values.
  6. All statistically significant P values (P < 0.05) are in bold.
