Other cardiovascular risk predictors directly related to CP with significant or almost significant values were age (p < 0.001), disease duration (p = 0.003), HTN (p = 0.053), presence of MetS (p = 0.066), serum levels of C3 (p = 0.016), and the Framingham risk score (p < 0.001). This evidence concerns the gene C3 and hypertensive disorder.
