There were significant differences between type 2 CRS (group A) and non- type 2 CRS (group B) groups in patient age (p = 0.023), ischemic heart disease (p = 0.036), baseline eGFR (p < 0.001), systolic and diastolic blood pressure (both p < 0.001), the use of angiotensin converting enzyme inhibitor (ACEI), and angiotensin II receptor blockers (ARB) (p = 0.0491). Here, ACE is linked to coronary artery disorder.
