Key result
Age, sex, Euroscore, and lipids link to vascular or valvular calcification in a new CART tree.
Why the study?
Topography of vascular and valvular calcification may predict postoperative complications, but data on these calcifications remain scarce.
Observational (n=557)
A new CART-based classification using age, sex, Euroscore, and lipid profile may help categorize the topographic distribution of cardiovascular calcifications.

CT-derived calcification mapping may refine perioperative risk models; leaves open whether topography improves outcome prediction in prospective studies.
Aim: The topography of vascular and valvular calcification could help accurately predict cardiovascular post-operative complications. The data on these calcifications remains scarce. Purpose: Identify the topographic distribution of the ascending aortic, left heart valves and coronary calcifications. Materials & methods: We extracted 26 variables from 557 patients, hospitalized between 2017 and 2020. The topography of calcification was evaluated by thoracic CT scans. Both multivariate logistic regression and classification and regression tree (CART) were used for statistical analysis. Results: Several comorbidities were associated with vascular or valvular calcification. This study proposes a CART tree for patients according to their age, sex, Euroscore and lipid profile. Conclusion: The proposed classification could represent an important clinical tool. More studies are warranted to better prune the current CART algorithm.

Samaha et al. (2022) conducted an observational in Vascular and valvular calcification (n=557). Comorbidities and clinical factors (age, sex, Euroscore, lipid profile) was evaluated on Topographic distribution of ascending aortic, left heart valves and coronary calcifications. Clinical factors including age, sex, Euroscore, and lipid profile were associated with vascular or valvular calcification in 557 patients, forming the basis of a new CART classification tree.
