Abstract

Over the past century, multiple studies lacking the precision of today's advanced technology provided conflicting data on the effects of oxygen therapy in normoxic cardiac patients. More importantly, no randomized, blinded, controlled studies have shown a benefit of such treatment. Yet the use of supplemental oxygen is widespread in cardiac patients. In these conditions, inadvertent hyperoxia commonly occurs because of concerns to ensure sufficient oxygenation and because hyperoxia is not perceived to be detrimental. In recent years, there has been mounting evidence demonstrating the potential adverse effects of hyperoxia on the cardiovascular system. In this report, we review data examining the effects of supplemental oxygen in normoxic patients with acute presentations of coronary artery disease. It is also the aim of this report to emphasize the point that oxygen therapy might have major adverse physiologic effects that must be considered when it is employed.
