Does a machine learning model predict new cardiovascular events in patients with diabetes?
Machine learning algorithms using 12 routine clinical parameters can identify patients with diabetes at high risk for new cardiovascular events with moderate accuracy.
Effect estimate: AUC 0.72 (95% CI 0.66-0.77)
p-value: p=<0.01
We aimed to develop a machine learning (ML) model for predicting cardiovascular (CV) events in patients with diabetes (DM). This was a prospective, observational study where clinical data of patients with diabetes hospitalized in the diabetology center in Poland (years 2015-2020) were analyzed using ML. The occurrence of new CV events following discharge was collected in the follow-up time for up to 5 years and 9 months. An end-to-end ML technique which exploits the neighborhood component analysis for elaborating discriminative predictors, followed by a hybrid sampling/boosting classification algorithm, multiple logistic regression (MLR), or unsupervised hierarchical clustering was proposed. In 1735 patients with diabetes (53% female), there were 150 (8.65%) ones with a new CV event in the follow-up. Twelve most discriminative patients' parameters included coronary artery disease, heart failure, peripheral artery disease, stroke, diabetic foot disease, chronic kidney disease, eosinophil count, serum potassium level, and being treated with clopidogrel, heparin, proton pump inhibitor, and loop diuretic. Utilizing those variables resulted in the area under the receiver operating characteristic curve (AUC) ranging from 0.62 (95% Confidence Interval CI 0.56-0.68, P < 0.01) to 0.72 (95% CI 0.66-0.77, P < 0.01) across 5 nonoverlapping test folds, whereas MLR correctly determined 111/150 (74.00%) high-risk patients, and 989/1585 (62.40%) low-risk patients, resulting in 1100/1735 (63.40%) correctly classified patients (AUC: 0.72, 95% CI 0.66-0.77). ML algorithms can identify patients with diabetes at a high risk of new CV events based on a small number of interpretable and easy-to-obtain patients' parameters.
Nabrdalik et al. (Mon,) conducted a observational in Diabetes (Type 1 or Type 2) (n=1,735). Machine learning model (12 clinical parameters) was evaluated on Prediction of new cardiovascular events (AUC 0.72, 95% CI 0.66-0.77, p=<0.01). A machine learning model utilizing 12 discriminative clinical parameters predicted new cardiovascular events in patients with diabetes with an area under the curve of 0.72.
