Effects of cholesterol levels on outcomes of out-of-hospital cardiac arrest: a cross-sectional study

OBJECTIVEHigh cholesterol level is a risk factor for coronary artery disease, and coronary artery disease is a major risk factor for out-of-hospital cardiac arrest (OHCA). However, the effect of cholesterol level on outcomes of OHCA has been poorly studied. This study aimed to determine the effect of cholesterol level on outcomes of OHCA. METHODSThis cross-sectional study used the CAPTURES (Cardiac Arrest Pursuit Trial with Unique Registration and Epidemiologic Surveillance) project database in Korea. Multivariable conditional logistic regression analysis was performed to estimate the effect of cholesterol level on outcomes in OHCA. RESULTSIn all, 584 cases of OHCA were analyzed; those with cholesterol levels
