Background: Providing a noninvasive, rapid, and cost‑effective approach to diagnose of myocardial
infarction (MI) is essential in the early stages of electrocardiogram (ECG) signaling. In this article,
we proposed the new optimization method for support vector machine (SVM) classifier to MI
classification. Methods: After preprocessing ECG signal and noise removal, three features such as
Q‑wave integral, T‑wave integral, and QRS‑complex integral have been extracted in this study. After
that, different statistical tests have evaluated the matrix of these features. To more accurately detect
and classify the MI disease, optimizing the SVM classification parameters using the grasshopper
optimization algorithm (GOA) was first used in this study (that called SVM‑GOA). Results: After
applying the GOA on the SVM classifier for all three kernels, the final results of MI detection for
sensitivity, specificity, and accuracy were ۱۰۰% ± ۰%, ۱۰۰% ± ۰%, and ۱۰۰% ± ۰%, respectively.
The final results of different MI types’ classification after applying the GOA on SVM for polynomial
kernel were obtained ۱۰۰% ± ۰%, ۹۷.۳۷% ± ۰%, and ۹۴.۲% ± ۰.۲% for sensitivity and specificity
and accuracy, respectively. However, the results of both linear and RBF kernels that were used for
the SVM classifier method have also shown a significant increase after using GOA. Conclusion:
This article’s results show the highly desirable effect of applying a GOA to optimize different kernel
parameters used in the SVM classifier for accurate detection and classification of MI. The proposed
algorithm’s final results show that the proposed system has a relatively higher performance than
other previous studies.
