[0023] To better understand the above technical solutions, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.
[0024] In the detailed description below, numerous specific details are illustrated with examples to provide a comprehensive understanding of the relevant guidance. However, it will be apparent to those skilled in the art that this application can be practiced without these details. In other instances, well-known methods, procedures, systems, components, and / or circuits have been described at a relatively high level without detail to avoid unnecessarily obscuring aspects of this application.

[0026] Before providing a further detailed description of the embodiments of the present invention, the nouns and terms involved in the embodiments of the present invention will be explained, and the nouns and terms involved in the embodiments of the present invention shall be interpreted as follows.
[0027] (1) In response to, used to indicate the conditions or states on which the operation is performed depends. When the conditions or states on which the operation is performed are met, one or more operations may be performed in real time or with a set delay. Unless otherwise specified, there is no restriction on the order in which the multiple operations are performed.
[0028] (2) Based on, used to indicate the conditions or states on which the operation is performed depends. When the conditions or states on which it depends are met, one or more operations can be performed in real time or with a set delay. Unless otherwise specified, there is no restriction on the order of execution of the multiple operations.
[0029] This application provides a method for predicting the risk of cardiovascular diseases, particularly for the risk identification and prediction of coronary heart disease (CHD). With the accelerating aging of the global population and continuous changes in lifestyle, the incidence of coronary atherosclerotic heart disease (CHD) caused by atherosclerotic plaques is increasing year by year. When plaques rupture and thrombus formation occurs, it can easily induce myocardial infarction, heart failure, or even sudden death, becoming one of the leading causes of death among middle-aged and elderly people. Therefore, early and accurate diagnosis of CHD is of great clinical significance for improving patient prognosis and reducing mortality.
[0030] Currently, coronary angiography is considered the "gold standard" for diagnosing coronary heart disease (CHD) in clinical practice. However, this method is invasive and involves radiation exposure, limiting its widespread application in certain populations. Besides coronary angiography, electrocardiography (ECG), cardiac magnetic resonance imaging (MRI), and computed tomography (CT) are also commonly used auxiliary diagnostic tools in clinical practice. However, these techniques all have certain limitations. While ECG is simple to perform and inexpensive, its diagnostic specificity is relatively poor, especially in identifying early lesions. Cardiac MRI and CT offer high spatial resolution and image quality, but they are expensive, complex, and require a high degree of patient cooperation, making them difficult to popularize in primary healthcare settings. Therefore, developing a simple, non-invasive, economical, and widely applicable method for early assessment of CHD has significant clinical value.
[0031] Therefore, in order to solve the above-mentioned technical problems, this application provides a method for predicting the incidence risk of cardiovascular diseases. This method combines clinical indicators with image group feature data from CT images to achieve the identification of cardiovascular diseases, especially cardiovascular diseases. For more information on this method, please refer to [link to relevant documentation]. Figure 1 This includes the following steps:
[0032] Step S11. Obtain the clinical data of the patient to be diagnosed and the image group feature data of the target region of the patient to be diagnosed.
[0033] In this embodiment, the method uses a joint prediction approach to assess the risk of coronary heart disease. The logic of the joint prediction approach is to obtain the score corresponding to each indicator based on the nomogram through the prediction model, and then obtain the total score. The total score is used to determine the risk level of cardiovascular disease, especially the risk level of coronary heart disease.
[0034] In this embodiment, the target area is the location of the right clavicular artery. The imaging feature data includes ultrasound image feature data, and the clinical data includes basic medical data and biophysical and chemical data. The basic medical data is the rate of change of blood pressure per unit time, and the biophysical and chemical data includes body mass index, triglyceride content, triglyceride-glucose index, and lipoprotein a content.
[0035] To acquire radiomics features, ultrasound images of the patient's right clavicular artery were first obtained. Then, regions of interest were manually delineated along plaque boundaries, and radiomics features were extracted. Based on the acquired radiomics features, statistical analysis was performed using SPSS 26.0 software. Count data were expressed as n (%), and the chi-square test was used to assess differences between groups. Normally distributed continuous data were expressed as mean ± standard deviation, and the independent samples t-test was used to assess differences between groups. Non-normally distributed continuous data were expressed as median, and the Mann-Whitney U test (rank-sum test) was used to assess differences between groups. Variables statistically significant in the univariate logistic regression analysis were further analyzed using multivariate logistic regression for feature selection. A binary logistic regression model was established. Receiver operating characteristic (ROC) curves for different models were plotted using MedCalc (Version 20.2) statistical software, and the area under the curve, sensitivity, specificity, and accuracy were calculated to evaluate the diagnostic efficacy of the models. The DeLong test was used to verify whether the differences in the AUC of the ROC curves of different models were statistically significant. Decision curve analysis was performed using R software, and charts were optimized using Adobe Photoshop 2022. A p-value < 0.05 indicates statistical significance. A total of 1125 radiomics features were extracted from the ultrasound images of the plaques. Using the aforementioned screening method, the top 10% of features most important for classification were selected, resulting in 113 features. Then, using the "Select by Model - Logistic Regression" component with L2 regularization and 5-fold cross-validation, redundant features with accuracy below the threshold were removed, ultimately retaining 14 features. The selected features include multiple first-order features, multiple gray-level co-occurrence matrix features, neighborhood gray-level difference matrix features, gray-level size region matrix features, multiple gray-level correlation matrix features, 2D shape features, and multiple gray-level run-length matrix features.
[0036] The first-order features include first-order feature skewness and first-order feature minimum; the multiple gray-level co-occurrence matrix features include the information metric correlation 1 of the gray-level co-occurrence matrix, the maximum correlation coefficient of the gray-level co-occurrence matrix, and the correlation of the gray-level co-occurrence matrix; the neighborhood gray-level difference matrix features include the busyness of the neighborhood gray-level difference matrix; the gray-level size region matrix features include the region size non-uniformity of the gray-level size region matrix; the 2D shape feature is the perimeter; the gray-level correlation matrix features include the busyness of the gray-level correlation matrix, the low gray-level emphasis of the small dependency of the gray-level correlation matrix, and the high gray-level emphasis of the large dependency of the gray-level correlation matrix; the gray-level run length matrix features include the run variance of the gray-level run length matrix, the normalized run length non-uniformity of the gray-level run length matrix, and the run entropy of the gray-level run length matrix.
[0037] Step S12. Input the clinical data and the imaging group feature data into the risk prediction model to calculate the risk value.
[0038] In this embodiment, the risk prediction model is a nomogram model. The nomogram model obtains the total score by mapping the scores corresponding to the multiple biophysical and chemical data and image group feature data obtained in step S11, and based on the score corresponding to each indicator and image group feature data. This total score is the risk value in this embodiment, which is used to characterize the risk level corresponding to coronary heart disease.
[0039] Specifically, based on the nomogram, the first score, second score, third score, fourth score, fifth score, and sixth score corresponding to the blood pressure change rate per unit time, the body mass index, the triglyceride content, the triglyceride-glucose index, the lipoprotein a content, and the image group feature data, as well as the corresponding total score, are obtained.
[0040] For the calculation results of this nomogram model, please refer to [link / reference]. Figure 2, where radsocre is the overall calculated score of the image group feature data, i.e., the sixth score value. The Radscore is calculated based on the following formula: Radscore = +0.094 × First-order feature skewness - 0.083 × Busyness of the neighborhood gray-level difference matrix + 0.081 × Small dependence and low gray-level emphasis of the gray-level correlation matrix - 0.081 × Minimum value of the first-order feature + 0.076 × Large dependence and high gray-level emphasis of the gray-level correlation matrix + 0.070 × Run variance of the gray-level run length matrix 0.070 × Perimeter + 0.064 × Information metric correlation of the gray-level co-occurrence matrix - 0.062 × Maximum correlation coefficient of the gray-level co-occurrence matrix - 0.060 × Normalized run length non-uniformity of the gray-level run length matrix + 0.053 × Region size non-uniformity of the gray-level size region matrix - 0.052 × Run entropy of the gray-level run length matrix + 0.050 × Correlation of the gray-level co-occurrence matrix + 0.044 × Dependence variance of the gray-level dependency matrix + 0.031.
[0041] For the specific calculation process of the nodal graph in this embodiment, please refer directly to [the relevant documentation / reference]. Figure 2 As shown, the calculation logic of the nodal chart can be used to achieve this, and will not be elaborated further in this embodiment.
[0042] In summary, by combining the above-mentioned multiple sets of clinical indicators and multiple sets of imaging feature data in this embodiment, the risk of cardiovascular diseases can be effectively assessed and predicted. This scoring data can more intuitively determine the severity of coronary heart disease, thereby achieving the identification of the risk of cardiovascular diseases.
