ClinConnect Summary

The NITRATE-CIN trial is a single-centre, randomised double-blinded placebo-controlled trial, which plans to recruit, over a period of 2 years, 640 patients presenting with acute coronary syndromes (ACS) who are at risk of CIN.

Patients will be randomised to either dietary inorganic nitrate therapy or placebo.

The primary endpoint will be the development of CIN (KDIGO criteria). A key secondary endpoint will be whether nitrate therapy impacts upon persistent renal impairment over a 3-month follow-up period. Additional secondary endpoints include the measurement of serum renal biomarkers (...
