Objective This study aims to explore the value of myocardial markers in predicting the risk of cardiac events in patients with asymptomatic heart disease. Methods A prospective cohort study design was adopted. A total of 500 patients diagnosed with asymptomatic heart disease in our hospital from September 2021 to March 2023 were included. They were divided into a high-level group and a low-level group according to the levels of myocardial markers and were followed up for 24 months to observe the relationship between the levels of myocardial markers and the occurrence of cardiac events (such as myocardial infarction, heart failure, etc.). Results The average content of myocardial specific markers in the high-concentration group was significantly higher than that in the low-concentration group. Meanwhile, the rate of heart attacks in the high-concentration group was also much higher than that in the ultra-low concentration group (34% compared with 18%). The analysis results of multivariate Cox regression indicated that the values of cardiac troponin T, cardiac troponin I and brain natriuretic peptide could independently predict the occurrence of cardiac events. Conclusion Cardiac function indicators, especially troponin T, troponin I and brain natriuretic peptide, play an important indicative role in predicting the risk of cardiac problems for those patients with heart disease who do not show obvious symptoms on the surface. These research results highlight the necessity of evaluating myocardial function indicators for such patient groups in medical practice. This not only helps to assess and respond to risks in advance, but also benefits in reducing the overall burden of cardiac health for patients.
