Popis: Purpose The threat of myocardial ischemia (MI) to human health is recognized worldwide. Most of the technologies currently used for disease screening have various disadvantages and it is difficult for them to play a role in clinical physical examination. Infrared thermography (IRT) has been a successful technology in a lot of clinical research. This study tried to establish a screening method for male MI with a high detection rate by IRT technology. Method A method for measuring symmetry based on low temperature sensitivity was proposed to extract the symmetry features of the IRT of the three groups of research subjects (93 persons in total) and a statistical test was performed to this method. If there was statistical significance, a mathematical model for classification would be constructed. In order to explore the value of IRT for MI screening, a double-blind comparison was made between the most common clinical method, ECG stress test (EST) and the method proposed in this study. The sensitivity, specificity and screening detection rate of the two methods to MI were calculated. Result After one-way analysis of variance (ANOVA), it could be drawn that the measurement features of the symmetry extracted in the sample had significant statistical differences among the three groups (P Conclusion MI can be screened by IRT non-invasively and non-radiatively. The measurement method and fuzzy classification model proposed can screen MI quickly. This study has played a certain role in the promotion of IRT in the field of MI screening. In subsequent research, more accurate inspection techniques will be integrated to further promote cardiac function measurement technology, contributing to human health.
