P: p value for comparing between the studied groups.p1: p value for comparing between unstable angina with each other groups.p2: p value for comparing between successful thrombolysis and failed thrombolysis.F: F test (ANOVA).Sch: Post Hoc Test (Scheffe).χ2: Chi square test.*Statistically significant at p ≤ 0.05.
