Higher baseline hs-CRP levels were linearly associated with an increased risk of cardiovascular disease (p for trend=0.015) and improved risk reclassification by 7.85% over traditional factors.

Is high-sensitivity C-reactive protein associated with an increased risk of cardiovascular disease in a middle-aged Chinese population?
Baseline hs-CRP is an independent predictor of cardiovascular disease in a middle-aged Chinese population and improves risk reclassification beyond traditional risk factors.
p-value: p=0.015
BACKGROUND: This study aimed to assess the association of high sensitivity C-reactive protein (hs-CRP) with cardiovascular disease (CVD) in middle-aged Chinese population. METHODS: The baseline was collected 2009-2010, and follow-up was conducted in 2016-2017. Data of hs-CRP were from baseline examination and re-examination in 2016-2017 using transmission turbidimetry with a measurement range of 0-42 000. The primary outcome was CVD including coronary heart disease events and stroke events. RESULTS: Among 8688 participants free from CVD (at baseline, mean age, 50.1 years, 3897 were males), there were 189 CVD events, occurred during a median follow-up of 6.34 years (54 685 person-years at risk). From the Kaplan-Meier curve, we found that there was a progressive increase in CVD event rates by hs-CRP tertiles (log-rank test, p<0.001). Baseline hs-CRP was linearly associated with CVD (p for trend=0.015) even after adjusting for known CVD risk factors. Furthermore, the net reclassification improvement when hs-CRP was added to a model based on traditional factors was 7.85% for CVD (p=0.003). In addition, the correlation between change of hs-CRP and CVD was conducted in a subgroup (n=4778). However, we did not find the correlation between hs-CRP change and CVD (correlation coefficient: -0.003, p=0.846). CONCLUSIONS: In the middle-aged Chinese population, hs-CRP was associated with increased risk of developing CVD. Although there was no correlation between hs-CRP change and CVD, the level of hs-CRP was higher at follow-up than baseline even among those with CVD. More attention should be given to those with higher level of hs-CRP for CVD prevention.
Dong et al. (Fri,) conducted a cohort in Cardiovascular disease (n=8,688). High-sensitivity C-reactive protein (hs-CRP) vs. Lower hs-CRP levels was evaluated on Cardiovascular disease including coronary heart disease events and stroke events (p=0.015). Higher baseline hs-CRP levels were linearly associated with an increased risk of cardiovascular disease (p for trend=0.015) and improved risk reclassification by 7.85% over traditional factors.
