Cardiovascular Disease (CVD) remains the leading cause of death worldwide, primarily caused by blockages in coronary arteries due to plaques or fatty deposits. Early identification and precise diagnosis are crucial for timely treatment, reducing disease severity, improving patient quality of life, and preventing complications. Objective: To develop an advanced, interpretable, and accurate CVD detection framework that addresses limitations in conventional methods related to feature representation and capturing complex relationships within the data. The model initiates with data cleaning to eliminate errors and inconsistencies, followed by Dynamic Gaussian Piecewise Normalization (DGPN) to handle heterogeneous and complex datasets, thereby improving feature representation. Multiobjective Weighted Restricted Boltzmann Machines (RBM) extract salient features, with weights optimized via a Revised Fitness-Oriented Bobcat Optimization Algorithm (RFO-BOA) employing multi-objective functions. An Adaptive Residual Capsule Network enhanced with Coordinate Attention (ARCCA) is employed to identify complex spatial and hierarchical patterns, increasing detection accuracy. The parameters of ARCCA are finely tuned through RFO-BOA to further elevate performance. Extensive experiments conducted on two benchmark cardiovascular datasets demonstrate the robustness and efficacy of the proposed model. The RFO-BOA–ARCCA approach achieved significant accuracy improvements of approximately 15.94%, 2.56%, 8.12%, and 3.89% over traditional models, including ANN, LSTM, SVM, and CapsNet, respectively. The integrated framework combining advanced data preprocessing, multi-objective feature extraction, and an optimized capsule network effectively facilitates early and accurate CVD detection. This framework holds promise for real-time clinical applications, enabling improved patient outcomes.
