Abstract:
The degree of Ca2+ leakage from the sarcoplasmic reticulum (SR) in cardiomyocytes can lead to dysfunction in both contraction and relaxation, potentially triggering arrhythmias. Therefore, it is crucial to develop simple and effective methods for quantitatively detectinga Ca2+ leakage. In this study, we employed an asymmetric Gaussian function to accurately fit the signals in confocal scanning Ca2+ signal images, facilitating the separation of noise from the calcium signals. We introduced two new feature parameters, Rca2+leak and Pca2+leak, for the quantitative assessment of calcium leakage. Given the subtle differences in calcium signal characteristics, visually distinguishing the states of cardiomyocytes can be challenging. To address this, we applied machine learning techniques in conjunction with the newly developed parameters to classify the states of cardiomyocytes, thereby inferring their pathological conditions. Our approach utilizes a straightforward and efficient methodology to propose two new parameters that effectively quantify the degree of calcium leakage. By integrating these new parameters, we achieved a classification accuracy for pathological states of cardiomyocytes that is 2% to 6% higher than that obtained with traditional feature classification methods. © 2024 Copyright held by the owner/author(s).
