Objective: To investigate the correlation between EFV and severity of coronary artery stenosis using cardiac-CT in CAD subjects at Hasan Sadikin Hospital Bandung. Methods: It is an analytical observational study with a crosssectional design using retrospective data with ANOVA and Chi-square statistical testing. The EFV and severity of coronary artery stenosis were quantified from diagnosed CAD subjects and underwent cardiac-CT in Hasan Sadikin Hospital Bandung from January2018-August 2018. Results: In 33 subjects there were 16 male (48.5%), 17 female (51.5%), there were 9 mild (27.3%), 9 moderate (27.3%), and 15 severe (45.5%) stenosis. Abnormal EFV (>125 ml) were 14 subjects (42.4%) found most in severe stenosis (30.3%). Chi-Square analysis showed that EFV had a significantly positive correlation with coronary artery stenosis (p=0.006), respectively. Conclusion: EFV demonstrated a positive correlation with the severity of coronary artery stenosis in CAD subjects using cardiac-CT at Hasan Sadikin Hospital, Bandung.
