Insights
Iso-osmolar contrast media (IOCM) may reduce major adverse renal and cardiovascular events (MARCE) in patients undergoing angioplasty compared to low-osmolar contrast media (LOCM). This finding suggests IOCM could improve patient outcomes in interventional cardiology.
Area of Science:
- Interventional Cardiology
- Nephrology
- Cardiovascular Medicine
Background:
- Contrast media (CM) are essential for angioplasty procedures.
- Assessing the safety of different CM types is crucial for patient outcomes.
- Major adverse renal and cardiovascular events (MARCE) are significant complications.
Purpose of the Study:
- To evaluate the association between iso-osmolar contrast media (IOCM) and low-osmolar contrast media (LOCM) and MARCE.
- To determine if CM type influences adverse event rates in angioplasty patients.
Main Methods:
- Retrospective analysis of 333,533 angioplasty visits across 357 hospitals.
- Stratification of visits into IOCM and LOCM cohorts.
- Multivariable regression analysis with hospital fixed effects to assess MARCE risk.
Main Results:
- The overall incidence of MARCE was 7.41%.
- Administration of IOCM, compared to LOCM, was associated with a 0.69% absolute risk reduction in MARCE.
- A 9.32% relative risk reduction in MARCE was observed with IOCM use.
Conclusions:
- IOCM may be associated with a reduction in MARCE compared to LOCM in patients undergoing coronary or peripheral angioplasty.
- Findings suggest IOCM could be a safer contrast media choice for reducing adverse events in this patient population.
Aim:
To assess the relationship between type of contrast media (CM), iso-osmolar contrast media (IOCM) or low-osmolar contrast media (LOCM), and major adverse renal and cardiovascular events (MARCE).
Materials & Methods:
Coronary or peripheral angioplasty visits were stratified into CM cohorts: IOCM or LOCM. Multivariable regression analysis used hospital fixed effects to assess the relationship between MARCE events and type of CM.
Results:
Among 333,533 visits (357 hospitals), the incidence of MARCE was 7.41%. After controlling for observable and unobservable time invariant within-hospital characteristics, administration of IOCM versus LOCM was associated with a 0.69% absolute and 9.32% relative risk reduction in MARCE rate.
Conclusion:
Our study indicates that as compared with LOCM, IOCM may be associated with reduction of MARCE events in coronary or peripheral angioplasty patients.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
