Abstract

Iohexol 350 mg I/ml (Omnipaque) was compared with the routine contrast medium meglumine, Na-Ca-metrizoate 370 mg I/ml (Isopaque Coronar) in coronary angiography in 30 patients. A randomized, double blind, cross-over design was employed. Angiographic image quality, ECG, heart rate, aortic blood pressure and adverse reactions were recorded. Excellent image quality was obtained with both media. Except for one single event of hypotension, only few and minor changes in the parameters measured were recorded. No distinct difference between the two media was found. Iohexol seems to be suitable for selective coronary angiography.

Abstract

The first investigation of iohexol in human cardioangiography is presented. Slight subjective reactions as well as moderate and transient influence on hemodynamics and ECG parameters were recorded. Analysis of serum enzymes indicated no myocardial injury. Good or excellent films of the left ventricle, aortic root and coronary arteries were obtained.

Abstract

Beat-by-beat heart rate (HR) changes during exercise were studied in two young and fit heart-transplanted humans at different time intervals following transplantation. Upon the start of the exercise, a slow gradual increase in HR was seen during the early experiments after the transplantation, whereas an immediate rapid increase in HR was observed during the later experiments. From standard ECGs obtained 32 months after transplantation, two P waves at somewhat different rates could be identified in both subjects, probably arising from donor and recipient sinoatrial nodes, respectively. The two P wave rate changes during and following exercise were very similar. We conclude that these changes in the HR pattern and ECG must be due to reinnervation of the donor hearts, most likely by parasympathetic cardiac fibers.

Abstract

The first investigation of iohexol in human cardioangiography is presented. Slight subjective reactions as well as moderate and transient influence on hemodynamics and ECG parameters were recorded. Analysis of serum enzymes indicated no myocardial injury. Good or excellent films of the left ventricle, aortic root and coronary arteries were obtained.
