AstraMedica: An AI-Powered Multi-Modal Healthcare System for Clinical Decision Support and Lifestyle Intervention

—Modern healthcare infrastructure faces severe pres sure from rising chronic disease prevalence, unequal distribu tion of specialist physicians, and fragmented diagnostic ser vices. To resolve these systemic bottlenecks, this paper presents AstraMedica—an integrated, multi-modal artificial intelligence healthcare assistance platform engineered for end-to-end clin ical decision support. AstraMedica unifies five specialized mi croservices: (1) automated electrocardiogram (ECG) arrhyth mia classification via deep residual networks; (2) blood report parameter parsing using clinical natural language processing (NLP) and optical character recognition (OCR); (3) bone frac ture localization using YOLOv8 coupled with spatial-attention ResNet152V2; (4) multi-pathology lung radiological screening using DenseNet-121 and 3D CNNs; and (5) a clinically grounded food recommendation engine integrated with an automated medication adherence notification subsystem. Built on a modular microservices architecture utilizing React.js, a Node.js security API gateway, Python Flask model inference servers, and dual-tier MongoDB/MySQLstorage, AstraMedica achieves high diagnostic throughput while maintaining clinical data privacy. Experimental evaluation demonstrates robust clinical utility: 97.4% accuracy (AUC 0.982) for ECG analysis, 94.2% accuracy for blood parsing, 92.2% accuracy on bone fracture localization, 93.8% accuracy (AUC 0.945) for pulmonary screening, with sub-4.2s end-to-end system latency.
