A novel nutritional index and adverse outcomes in ischemic stroke: Results from the third China National Stroke Registry.

Abstract

BACKGROUND AND AIMS:

Few studies have applied the triglyceride, cholesterol, body weight index (TCBI) in acute ischemic stroke (AIS). We investigated the association between the TCBI and adverse clinical outcomes in patients with AIS.

METHODS AND RESULTS:

Based on the Third China National Stroke Registry (CNSR-III) data from August 2015 to March 2018, we evaluated the nutritional status of patients with AIS using the TCBI. Patients were categorized according to quartile levels of the TCBI. The main outcomes were poor functional outcomes and recurrent stroke at 1-year and secondary outcomes were adverse outcomes at 3 and 6 months after stroke onset. Poor functional outcomes consisted of all-cause mortality and major disabilities. Multivariate analyses with logistic or Cox regression analysis and restricted cubic splines determined the association between the TCBI and adverse outcomes. We included 9708 patients. At the 1-year follow-up, 1323 patients (13.6%) had died or experienced major disability. The adjusted odds ratios/hazard ratios and 95% confidence intervals of the lowest quartile at 1-year were 1.47 (1.22-1.78) for poor functional outcomes, 1.46 (1.18-1.81) for major disability, and 1.34 (0.94-1.86) for all-cause mortality. Kaplan-Meier analysis demonstrated an inverse relationship between all-cause mortality and the TCBI (log-rank p < 0.05). An approximately L-shaped relationship between TCBI levels and poor functional outcomes and major disability was observed at 1-year.

CONCLUSION:

The novel TCBI was associated with short- and long-term adverse outcomes in AIS. Thus, it may be useful for predicting adverse outcomes in patients with AIS.
