Nightcall PCI Procedures Don’t Affect Cardiologists’ Daytime Outcomes

Medical Research: What is the background for this study? What are the main findings?

Dr. Aronow: Psychomotor and cognitive performance may be impaired by sleep deprivation.  Interventional cardiologists perform emergent, middle-of-the-night procedures, and may be sleep-deprived as a consequence.  Whether performance of middle-of-the-night percutaneous coronary intervention (PCI) procedures impacts outcomes associated with PCI procedures performed the following day is not known. 

Medical Research: What should clinicians and patients take away from your report?

Dr. Aronow: In a large registry study of ~ 1.5 million patients who underwent PCI in the US, we found that the incidence of bleeding or death following daytime PCI procedures, was no different in the hands of operators  who had performed similar procedures the night before than in the hands of operators who had not.  A number of other adverse procedural outcomes were also no different between groups.  These findings suggest that our current system of providing life saving middle-of-the-night cardiovascular care does not jeopardize the safety of PCI procedures performed under the light of day.

Medical Research: What recommendations do you have for future research as a result of this study?

Dr. Aronow:  Future research should focus on factors that impact outcomes associated with middle-of-the-night PCI procedures.
