Study reports that delaying surgery post-COVID-19 reduces the risk of postoperative cardiovascular issues

By Neha MathurDec 16 2022Reviewed by Aimee Molineux In a recent article published in JAMA Network Open, researchers assessed the temporal relationship between COVID-19 diagnosis and surgery time with the risk of occurrence of cardiovascular morbidity events within 30 days of surgery.

More importantly, COVID-19 increases the risk of heart-related disorders and acute kidney injury owing to its effects, such as regional hyperinflammation and excessive cytokine release. There is a need to investigate how the time from COVID-19 diagnosis to surgery is associated with the risk of postoperative cardiovascular morbidity.

Study findings The study population comprised 3997 patients, Blacks, White, and other races, with a median age of 51.3 years. The average time between COVID-19 diagnosis and surgery was 98 days. The researchers noted adverse postoperative cardiovascular events in 485, i.e., 12.1% of the patients. Further, they found that increasing the time between COVID-19 diagnosis and surgery decreased the rate of the combined adverse postoperative outcomes, with an adjusted odds ratio of 0.99.
