Coenzyme Q10 (CoQ10) has a potential role in the prevention and treatment of heart failure through improved cellular bioenergetics. In addition, it has antioxidant, free radical scavenging, and vasodilatory effects that may be beneficial. Although critical illness in intensive care unit is associated with decreased circulating CoQ10 levels, the clinical significance of CoQ10 levels during acute phase in the patients of cardiovascular disease remains unclear. We enrolled 257 consecutive cardiovascular patients admitted to the coronary care unit (CCU). Serum CoQ10 levels were measured after an overnight fast within 24 h of admission. We examined the comparison of serum CoQ10 levels between survivors and in-hospital mortalities in patients with cardiovascular disease. Serum CoQ10 levels during the acute phase in patients admitted to the CCU had similar independent of the diagnosis. CoQ10 levels were significantly lower in patients with in-hospital mortalities than in survivors (0.43 ± 0.19 vs. 0.55 ± 0.35 mg/L, P = 0.04). In patients admitted to the CCU, CoQ10 levels were negatively associated with age and C-reactive protein levels, and positively associated with body mass index, total cholesterol, and high-density lipoprotein cholesterol levels. Low CoQ10 levels correlated with low diastolic blood pressure. Multivariate logistic regression analysis demonstrated that low CoQ10 levels were an independent predictor of in-hospital mortality. Low serum CoQ10 levels during acute phase are significantly associated with cardiovascular risk and in-hospital mortality in patients admitted to the CCU.
