Preprints with The Lancet is part of SSRN´s First Look, a place where journals and other research experts identify content of interest prior to publication. These preprint papers are not peer-reviewed and are posted here as part of a 12-month trial. Authors have either opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet, or submitted directly via SSRN. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. These papers should not be used for clinical decision making or reporting of research to a lay audience without indicating that this is preliminary research that has not been peer-reviewed.

Abstract

Background: Impaired glucose tolerance (IGT) promotes cardiovascular events in myocardial infarction (MI) patients. However, our randomized trial (the ABC study) showed that alpha-glucosidase inhibitors do not prevent cardiovascular events in patients with MI and IGT. The aim of the present study is to identify potential clinical factors for cardiovascular and coronary events in patients with a MI and IGT.

Methods: Using the limitless-arity multiple testing procedure, an artificial intelligence (AI)-based data mining method, we analyzed 385,391 combinations of fewer than four clinical parameters.

Findings: We identified 380 combinations predicting the occurrence of (1) all-cause hospitalisation, (2) hospitalisation due to worsening of heart failure (HF), (3) hospitalisation due to non-fatal MI, and (4) hospitalisation due to percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for stable angina among 385,391 combinations in 853 patients. Among these, either plasma BNP levels >200 pg/dl or diuretic use exclusively predicted (1) all-cause hospitalisation, (2) hospitalisation due to worsening of HF, and (3) hospitalisation due to a non-fatal MI, with plasma BNP levels >200 pg/dl being the sole predictor of hospitalisation due to PCI and CABG. Importantly, each finding was verified by independently drawn Kaplan-Meier curves, revealing the unexpected role of plasma BNP levels in the progression of coronary stenosis determined as the necessity of PCI and CABG for stable angina.

Interpretation: In patients with MI and IGT, plasma BNP levels >200 pg/dl predicted the occurrence of coronary stenosis, recurrent MI and worsening of HF, whereas diuretic use did not predict the progression of coronary stenosis but non-fatal MI and worsening of HF We also demonstrated the use of AI in cardiovascular medicine.

Funding: Grants-in-Aid from the Ministry of Health, Labour and Welfare of Japan; and Grants-in-Aid from the Japan Agency for Medical Research and Development.
