Comparison of Hexabrix 320 and Conray 420 for left ventriculography in patients with coronary artery disease
Insights
Hexabrix 320 caused less discomfort than Conray 420 during left ventriculography. However, Conray 420 provided better angiographic quality, making it more suitable for routine use.
Area of Science:
- Cardiology
- Radiology
- Medical Imaging
Background:
- Left ventriculography is a key diagnostic procedure in cardiology.
- Contrast media used in angiography can cause patient discomfort and affect hemodynamic parameters.
- Comparing different contrast agents is crucial for optimizing patient safety and diagnostic accuracy.
Purpose of the Study:
- To compare the safety and efficacy of Hexabrix 320 versus Conray 420 in left ventriculography.
- To evaluate patient tolerance, hemodynamic effects, and image quality between the two contrast agents.
Main Methods:
- Prospective, randomized, double-blind study involving 100 patients with suspected coronary disease.
- Patients received either Hexabrix 320 or Conray 420 for left ventriculography.
- Data collected included patient-reported discomfort, hemodynamic changes, and angiographic quality.
Main Results:
- Hexabrix 320 was associated with significantly less patient-reported warmth and discomfort compared to Conray 420 (p<0.01 and p<0.02).
- Angiographic quality was superior with Conray 420 (p<0.05).
- Hemodynamic changes, including heart rate and systolic pressure, were similar, though Conray 420 showed greater systolic pressure variation (p<0.025) and a larger increase in end-diastolic pressure (p<0.05).
Conclusions:
- While Hexabrix 320 offers improved patient comfort, Conray 420 provides better image quality for left ventriculography.
- The benefits of Hexabrix 320 may be relevant for specific patient groups, but Conray 420 is preferred for routine diagnostic angiography.
Abstract:
We compared Hexabrix 320 (580 mOsm kg-1) with Conray 420 (2500 mOsm kg-1) for left ventriculography using a prospective randomised double-blind protocol. One hundred consecutive patients with suspected coronary disease were assigned to Hexabrix (52) or Conray (48) for left ventriculography (dose 10 ml m-2 BSA; flow rate 12 ml s-1). Thirteen patients found Hexabrix unpleasant compared with 24 receiving Conray; overall the feelings of warmth and discomfort were less with Hexabrix than Conray (p less than 0.01 and p less than 0.02 respectively). The incidence of nausea, vomiting, and hypersensitivity was similar. Angiographic quality was better with Conray than with Hexabrix (p less than 0.05). Average changes in heart rate and systolic pressure were similar, though there was greater variation in systolic pressure change after Conray (p less than 0.025). End diastolic pressure increased more after Conray than after Hexabrix (p less than 0.05). These slight advantages of Hexabrix over Conray may be valuable in patients requiring multiple angiograms or in those with impaired cardiac function, but do not justify its use for routine angiography.
