AbstractBackgroundEarly screening is important in individuals with spinal cord injury (SCI) as they are deemed high risk for cardiometabolic diseases. Few studies explored changes in cardiometabolic risk profile in the early phase of the injury. Thus it remains unclear how early the cardiometabolic status deteriorates after injury.ObjectiveTo determine the longitudinal changes in the cardiometabolic risk profile and examine the association between injury characteristics and cardiometabolic status in subacute SCI.SettingMulticenter Swiss Spinal Cord Injury Cohort.ParticipantsAdults with traumatic SCI without a history of cardiovascular disease or type 2 diabetes.Main Outcome MeasuresBlood pressure (BP), lipid profile, fasting glucose, waist circumference (WC), weight, body mass index (BMI), and Framingham risk score (FRS) were compared across time and according to the injury characteristics.ResultsWe analyzed the data of 258 individuals with traumatic SCI (110 tetraplegia and 148 paraplegia, 122 motor complete, and 136 incomplete). The median age was 50 years (interquartile range [IQR] 32‐60), with 76.4% (n = 197) of the population being male. The median rehabilitation duration was 5.5 months (IQR 3.2‐7.1). At admission to rehabilitation, fully adjusted linear regression models showed higher baseline weight (β 0.06, 95% confidence interval [CI] 0.005 to 0.11), systolic BP (β 0.05, 95% CI 0.008 to 0.09), diastolic BP (β 0.05, 95% CI 0.004 to 0.10), and triglycerides (β 0.27, 95% CI 0.13 to 0.42) in paraplegia than tetraplegia. Systolic BP, diastolic BP, high‐density lipoprotein cholesterol (HDL‐C) levels were higher in incomplete than complete injury. In our main analysis, we observed an increase in cholesterol and HDL‐C and lipid ratio when comparing the beginning and end of rehabilitation. Individuals with paraplegia had a higher increase in BMI than individuals with tetraplegia, whereas no differences in other cardiometabolic risk factors were detected when comparing motor incomplete and complete injury. Trajectories of each participant showed that the majority of individuals with SCI decreased FRS score at follow‐up compared to baseline and no significant changes in the prevalence of cardiometabolic syndrome were observed. At discharge, one third of study participants were classified as moderate to high risk of cardiovascular disease (CVD), 64% were overweight, and 39.4% had cardiometabolic syndrome.ConclusionWe observed a modest improvement in lipid profile and FRS during the first inpatient rehabilitation hospitalization. Injury characteristics, such as level and completeness, were not associated with changes in cardiometabolic risk factors in the subacute phase of the injury. Despite this, a significant proportion of study participants remained at risk of cardiometabolic disease at discharge, suggesting that early cardiometabolic preventive strategies may be initiated as early as during the first inpatient rehabilitation hospitalization.
