Canada Acute Coronary Syndrome Score: A Preprocedural Risk Score for Contrast-Induced Nephropathy After Primary...

Area of Science:

• Cardiology
• Nephrology
• Clinical Risk Prediction

Background:

• Contrast-induced nephropathy (CIN) is a significant complication post-primary percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) patients, leading to adverse outcomes.
• Predictive tools for CIN are crucial for risk stratification and management in this vulnerable population.

Purpose of the Study:

• To evaluate the predictive capability of the Canada Acute Coronary Syndrome (C-ACS) score for CIN.
• To assess the association between C-ACS score and major adverse clinical events (MACEs) and mortality in STEMI patients undergoing primary PCI.

Main Methods:

• A cohort of 394 STEMI patients undergoing primary PCI were analyzed.
• Patients were stratified into three groups based on C-ACS scores (0, 1, and ≥2).
• Outcomes assessed included CIN, in-hospital death, and long-term MACEs.

Main Results:

• 8.4% of patients developed CIN.
• Higher C-ACS scores were significantly associated with increased risk of CIN, in-hospital death, and MACEs (P < .001).
• The C-ACS score independently predicted CIN (OR = 2.87; 95% CI = 1.78-4.63; P < .001) and was a risk factor for long-term MACEs.

Conclusions:

• The C-ACS score demonstrates good predictive value for CIN and clinical outcomes in STEMI patients.
• Utilizing the C-ACS score can aid in identifying high-risk patients who may benefit from preventative strategies against CIN and adverse events.
