HealthDay News — People who experience an in-hospital cardiac arrest (IHCA) in the cardiac catheterization lab (CCL) are more likely to survive to discharge than those who experience an IHCA in the intensive care unit (ICU), according to a study presented at the American Heart Association Resuscitation Science Symposium 2021, to be held virtually from Nov. 12 to 14 as part of the annual meeting of the American Heart Association.
Ahmed Elkaryoni, M.D., from Loyola University Medical Center in Maywood, Il., and colleagues compared characteristics and outcomes of patients aged 18 years or older with an IHCA in the CCL, operating room (OR), or ICU (6,866; 5,181; and 181,832 patients, respectively)
The researchers found that compared with those in the OR and ICU, patients with IHCAs in the CCL were more likely to have a shockable cardiac arrest rhythm. Overall, 38.1 percent with IHCA in the CCL survived to discharge compared with 16.9 and 40.5 percent from the ICU and OR, respectively. Patients with IHCA in CCL were more likely to survive to discharge compared with those from the ICU after adjustment for 27 patient and cardiac arrest factors (odds ratio, 1.37). However, they were less likely to survive to discharge than those with ICHA in the OR (odds ratio, 0.81).
“In-hospital cardiac arrest in the cardiac catheterization lab is not uncommon and has a slightly lower survival rate when compared with in-hospital cardiac arrest in the OR,” Elkaryoni said in a statement. “The reasons for this difference, however, deserve further study given that cardiac arrest in both settings is witnessed and response time should be similar.”
