Do Cardiovascular Risk Factors and Coronary SYNTAX Score Predict Contrast Volume Use During Cardiac Catheterization?

Area of Science:

• Cardiology
• Interventional Cardiology
• Nephrology

Background:

• The relationship between cardiovascular risk factors, coronary artery disease (CAD) complexity, and contrast volume (CV) used during cardiac catheterization (CC) is not well understood.
• Predicting CV use is crucial for managing potential risks like contrast-induced nephropathy (CIN).

Purpose of the Study:

• To identify predictive factors associated with contrast volume (CV) utilization during elective and emergent cardiac catheterization (CC).
• To explore the association between cardiovascular risk factors, CAD severity, and CV in patients undergoing CC.

Main Methods:

• Retrospective review of electronic medical records from 2010 to 2013.
• Inclusion of 708 patients undergoing cardiac catheterization.
• Multivariable regression analysis to assess predictive factors of CV use.

Main Results:

• Obstructed coronary arteries were associated with lower CV (P = .01).
• Lesions >70% stenosis (P = .019) and ST-elevation myocardial infarction (P = .001) were linked to increased CV use.
• Elevated B-type natriuretic peptide (P = .036) and higher SYNTAX scores (P = .024) were associated with decreased CV use, though these associations were attenuated after adjusting for percutaneous coronary intervention (PCI).

Conclusions:

• Specific cardiovascular risk factors and CAD severity influence contrast volume during cardiac catheterization.
• Identifying patients at risk for higher CV use can aid in preventing contrast-induced nephropathy.
• Further research is needed to fully elucidate the interplay between PCI and CV in predicting CIN risk.
