Vitamin E and N-acetylcysteine for Preventing Contrast-Induced Acute Kidney Injury After Coronary Artery Catheterization

Phase 3
Conditions
Contrast-induced Nephropathy
Coronary Artery Angiography
Stable Angina
Coronary Catheterization
Coronary Artery Disease
Acute Coronary Syndrome
Interventions
Drug: Placebo oral capsule
Drug: Placebos
Drug: Normal Saline Flush, 0.9% Injectable Solution
Registration Number
NCT03755700
Lead Sponsor

Brief Summary

In a double-blinded randomized clinical trial, all patients undergoing coronary artery catheterization who will met our criteria, will be enrolled into three groups to receive either, vitamin e, n-acetylcysteine, or placebo. The aim of study will be to compare the superiority of vitamin e over n-acetylcysteine for the prevention of contrast-induced acute kidney injury (CIAKI).

Detailed Description

Patients aged ≥18 years with chronic kidney disease who undergo coronary catheterization will be enrolled into the study if they meet the inclusion criteria. Patients will be randomly assigned into three groups in a 1:1:1 ratio (Computer-generated random number will be used to assign a patient in either group): we will use simple randomization for assigning each patient in a group. The participants, physicians and outcome assessors will be blinded throughout the trial until the opening of the randomization cold.

All patients will be entered into three group and they will be given normal saline 0.9%, vitamin E, NAC, and the placebos of both regimens. The vitamin E will be given as a soft gel capsule and its placebo will have the same shape and taste. The NAC will be given as an effervescent tablet with a glass of water for consumption and its placebo will also have the same shape and taste. These drugs will be given in addition to the routine hydration therapy which will be given to all patients.

Primary outcome will be the development of CIAKI. Secondary outcomes will be the development of major adverse cardiovascular events and any events till evaluating the CIAKI within 48-72 hours after intervention.

Inclusion Criteria

Patients aged ≥18 years with baseline estimated glomerular filtration rate (eGFR) <60 mL/min per 1.73 m2 (based on the Modification of Diet in Renal Disease study group formula) who undergo coronary catheterization (i.e. coronary angiography and percutaneous coronary intervention [PCI]) will be invited to the study if they meet the inclusion criteria: stable angina with ischemia and indication for coronary angiography, non-ST-segment elevation (NSTE) acute coronary syndrome (ACS) requiring an early invasive strategy, and patients undergoing elective PCI .

Exclusion Criteria

acute ST-segment elevation myocardial infarction, high-risk NSTE-ACS warranting emergency coronary angiography (<2 hours), cardiogenic shock, pulmonary edema, overt heart failure and/or ejection fraction <30%, ACS undergoing coronary angiography or angioplasty during the previous 5 days, sensitivity to contrast medium, recent administration of contrast medium for any reason, AKI, history of dialysis, pregnancy, newly prescribed angiotensin converting enzyme inhibitors or angiotensin receptor blockers, bleeding and/or coagulopathy diseases, and consumption of nephrotoxic drugs, vitamin E, vitamin C, or N-acetylcysteine (NAC) at least 48 hours before intervention.
