2.2 Data source

We use the acute coronary syndrome dataset named as Korea Acute Myocardial Infarction Registry (KAMIR-NIH) [11], which is registered in 52 hospitals of Korea and containing all patients’ data from November 2011 to December 2019. We use the two-year dataset in our research work, containing 551 different attributes and 13,104 patients’ medical records with two-year follow-up after hospital discharge. However, there is restriction to share this data because the data is sensitive and not available publicly. Details information about the registry is located at the KAMIR website (http://www.kamir.or.kr). In our data sample, we have all basic medical information of patients such as age, blood pressure, heart rate, height, weight, other diseases record, and previous medical record of patients’ either suffering from any other disease, or have already heart failure, or what is the severity of patient. We have also the complete medication records for heart patients with two- year follow-up. This paper defines major adverse cardiovascular events (MACE) as cardiac death (CD), non-cardiac death (NCD), myocardial infarction (MI), re-percutaneous coronary intervention (re-PCI), and coronary artery bypass grafting (CABG).
