Conventional biomarkers for cardiovascular risks and their correlation with the castelli risk index-indices and tg/hdl-c

Objective: to evaluate the correlation between a group of conventional biomarkers of cardiovascular risk with the Castelli-I and Castelli-II indices, and TG/HDL-C ratio in patients assigned to a program of cardiovascular risk for users of the clinical laboratory service of an institution that provides health services in the southwest of the Colombia. Materials and Methods:  retrospective, descriptive multivariate exploratory study, carried out in 2 126 patients. Some sociodemographic variables were analyzed, as well as glucose and lipid profile. The Castelli-I and Castelli-II indices, and TG/HDL-C ratio were calculated. The correlation among the variables was evaluated through a matrix of correlations, the correlation index and the Bartlett’s Test of Sphericity. The analysis ended with a study of main components, which allowed to identify how the variables studied were grouped into components that characterized the population. Results:  the average age was 56 ± 11 years; 68.7% were women; 48% hypercholesterolemic and 49% hypertriglyceridemic; 22% with alterations in glucose. Total cholesterol correlated positively with LDL-C and triglycerides negatively with HDL-C. Two components characterized the population, one related to cardiovascular risk and the other to lipid alterations. Conclusions:  conventional biomarkers reveal high prevalences in dyslipidemias, in contrast to atherogenic indices. The results highlight the importance of considering the evaluation of these indices in primary care and the need to strengthen the measurement systems of clinical laboratories for the reliability of the data on which decisions are made for the management of these patients.
