Abstract

Objectives: To examine whether carbon monoxide (carboxyhaemoglobin) levels of patients admitted for myocardial ischaemia were higher than that of patients admitted for other illnesses

Methods: Patients coming in, at the Royal Adelaide Hospital, Australia, for admission were tested for their blood carboxyhaemoglobin level. Ethics approval was obtained from the University of Adelaide Ethics Committee. Blood was taken from those admitted for myocardial iscahemia and patients admitted at the same time for other illnesses, at the same time, to avoid any influence from environmental variation in CO levels. Blood was not taken, especially for the purpose, but the blood taken for other measures at the time of admission was made use of. Consent to use the blood for the purpose was obtained.

Results: Blood carboxyhaemoglobin levels of the two groups of patients were not significantly different.

Conclusion: Contrast to few other similar studies, the results were not as expected. This could be due to the fact that the patients were not exposed to sources of CO (e.g. smoking or environmental exposures), immediately prior to the myocardial ischemic episode. Also the sample size (485 both groups) may not have been sufficient to show a positive result. This does not disprove the fact that CO has a contributory effect on myocardial iscahemia.
