Why the study?

Does non-ionic contrast medium increase the risk of ventricular fibrillation and other serious arrhythmias compared to ionic contrast medium in patients undergoing coronary angiography?

Population

3660 patients undergoing coronary angiography

Comparison

Non-ionic contrast medium vs Ionic contrast medium

Design

Cohort

Discussion

Implication

Contrast type does not affect arrhythmia risk in coronary angiography; supports technical factors as primary driver but leaves open randomized confirmation.

Structured PICO

Does non-ionic contrast medium increase the risk of ventricular fibrillation and other serious arrhythmias compared to ionic contrast medium in patients undergoing coronary angiography?

Population

3660 patients undergoing coronary angiography

Intervention

Non-ionic contrast medium

Comparator

Ionic contrast medium

Outcome

Incidence of ventricular fibrillation and other serious arrhythmiassafety

Ventricular fibrillation during coronary angiography is rare and primarily related to technical factors rather than the choice between ionic and non-ionic contrast media.
