Abstract | BACKGROUND: METHODS AND RESULTS: Of 132 unselected patients with IC entering the study 78 (59%) were excluded due to: current ACE inhibitor use (38%), renal impairment (serum creatinine above normal range) (15%), known severe RAS (1%) or unwillingness to participate (5%). The remaining 54 patients were titrated to 10 mg ramipril and renal function was monitored at 1, 5, and 12 weeks. Treatment was discontinued during titration in 5 patients due to symptoms (3) or lack of compliance (2). In the remainder, median [IQR] serum creatinine increased (94 [85.8-103.3] to 98 [88.0-106.5] micromol/L, p < or = 0.001) and median [IQR] GFR decreased (71.5 [64.6-82.3] to 68.7 [59.8-74.7] mL/min per 1.73 m2, p < or = 0.001) between baseline and 5 weeks. These changes were not considered clinically significant. By 12 weeks these values had returned almost to baseline (Cr 95.5 [88.0-103.25] micromol/L, GFR 71.8 [65.3-77.4] mL/min). No patient had a serum creatinine rise > 30%. CONCLUSION: Most of patients with IC and a normal serum creatinine can be safely commenced on ramipril provided they are screened, titrated and monitored as described above. Studies in patients with borderline renal impairment (serum creatinine up to 30% above baseline) are on-going.
