1. Executive Summary

The Cardiology Intelligence Agent is a production-grade, RAG-powered clinical decision support system built for the HCLS AI Factory precision medicine platform running on NVIDIA DGX Spark. It delivers evidence-based cardiovascular guidance across the full spectrum of cardiology subspecialties -- from heart failure management and coronary artery disease to electrophysiology, valvular disease, cardiac imaging, preventive cardiology, and cardio-oncology -- by combining 12 domain-specific Milvus vector collections, six validated risk calculators, a four-pillar GDMT optimization engine, 18 cross-modal genomic triggers, and an autonomous reasoning pipeline that plans, searches, evaluates, and synthesizes clinical evidence in real time.

The agent is architected as a three-tier system: a Streamlit UI (port 8536) for interactive clinical exploration, a FastAPI REST API (port 8126) exposing 33 endpoints for programmatic integration, and a RAG engine backed by Milvus (port 19530) with BGE-small-en-v1.5 384-dimensional embeddings. All 11 clinical workflows, all 6 risk calculators, the GDMT optimizer, and the full query expansion system operate independently of Milvus connectivity, ensuring graceful degradation and robust demo capability even when the vector store is unavailable.

The codebase comprises 58 Python files totaling 44,451 lines of code, with 20 dedicated test files containing 11,450 lines and 1,966 passing tests at a 100% pass rate (1.08s execution time). The knowledge graph contains 45 cardiovascular conditions, 56 genes, 32 drug classes, 29 cardiac biomarkers, 15 imaging modalities, and 51 guideline recommendations from ACC/AHA/ESC sources. This report documents every capability, data dimension, and test result to serve as the definitive long-term reference for the Cardiology Intelligence Agent.

Component Interaction

The Streamlit UI communicates with the FastAPI backend via HTTP REST calls. The API layer dispatches queries through the RAG engine for evidence retrieval, the risk calculator engine for validated scoring, the GDMT optimizer for heart failure therapy recommendations, and the clinical workflow engine for condition-specific assessments. The RAG engine performs parallel multi-collection vector search against Milvus using workflow-specific collection weights, applies query expansion via 18 synonym maps, scores citations, and synthesizes responses through the Claude LLM. Cross-modal genomic triggers fire when clinical findings meet predefined thresholds (e.g., unexplained LVH >= 15mm), bridging bedside cardiology with the HCLS AI Factory's genomic pipeline on the same DGX Spark.

6.5 Comorbidity Adjustments

  • CKD (eGFR < 30): MRA contraindicated, ARNI start lower dose, SGLT2i limited data
  • Liver disease: Eplerenone caution with CYP3A4, ARNI avoid in Child-Pugh C
  • Frailty: Lower starting doses, slower titration, closer monitoring

6.6 HFpEF-Specific Therapies

SGLT2i (Class I, Level A), diuretics for congestion, manage comorbidities, GLP-1 RA for obese HFpEF, spironolactone (considered), exercise training.

11. Autonomous Agent Pipeline

The CardiologyIntelligenceAgent follows the VAST AI OS AgentEngine pattern:

Pipeline Stages

  1. Plan (search_plan()) -- Analyze question, identify conditions/drugs/imaging, select search strategy, decompose into sub-questions
  2. Search (rag_engine.query()) -- Execute multi-collection parallel retrieval with workflow-specific weights
  3. Evaluate (evaluate_evidence()) -- Assess evidence quality, completeness, currency, and relevance
  4. Synthesize -- Generate clinician-facing response via Claude LLM with CARDIO_SYSTEM_PROMPT
  5. Report (generate_report()) -- Format output with citations, risk scores, cross-modal triggers, clinical alerts

CARDIO_SYSTEM_PROMPT

Instructs the LLM to act as a cardiology clinical decision support system with expertise across all cardiovascular subspecialties, citing ACC/AHA/ESC guidelines with Class of Recommendation and Level of Evidence for every recommendation.

Search Strategy Selection

Strategy When Used Collection Focus
Broad General questions, multi-topic Equal weights across all collections
Targeted Specific condition/drug query Boosted weight on dominant collection
Comparative "A vs B" or "compare" queries Literature + trials weighted higher
Clinical Patient-specific with context Workflow-matched weights + guidelines

Fallback Handling

When prometheus_client is not installed, the module silently exports no-op stubs so the rest of the application can import metrics helpers without a hard dependency. All record_* methods become no-ops.

19. Scheduling & Automation

Scheduled Jobs (3)

Job Schedule Source Target Collection Description
PubMed Refresh Weekly (Sunday 2:00 AM) PubMed E-utilities API cardio_literature Fetch latest cardiology publications
Clinical Trials Refresh Weekly (Sunday 3:00 AM) ClinicalTrials.gov API cardio_trials Update trial statuses and results
Guideline Update Monthly (1st, 4:00 AM) Guideline document store cardio_guidelines Check for guideline updates

APScheduler Integration

  • Uses BackgroundScheduler from APScheduler
  • Jobs registered on application startup
  • Manual trigger capability via API endpoints
  • Job status tracking with last run time and next run time
  • Error handling with automatic retry on failure

20. Configuration System

Validation Logic

  • Weight sum validation: all workflow weight dicts must sum to ~1.0
  • Port range validation: 1024-65535
  • Embedding model validation: must be a valid model identifier
  • Score threshold validation: 0.0-1.0

21. Security & Authentication

API Key Authentication

  • Header: X-API-Key
  • Validated on all write/query endpoints
  • System/health/reference endpoints are public
  • API key loaded from CARDIO_API_KEY environment variable

CORS Configuration

  • Origins: configurable allow list
  • Methods: GET, POST, OPTIONS
  • Headers: Content-Type, X-API-Key, Authorization
  • Credentials: enabled

Rate Limiting

  • 100 requests per minute per IP address
  • Implemented via middleware
  • Returns 429 Too Many Requests when exceeded

Request Size Limiting

  • Maximum request body: 10 MB
  • Prevents denial-of-service via large payloads

Input Sanitization

  • All string inputs validated via Pydantic field validators
  • max_length constraints on all VARCHAR-backed fields
  • ge/le constraints on all numeric inputs
  • Regex patterns on enum-like string fields (sex, race)
  • SQL/NoSQL injection prevented by parameterized Milvus queries

22. Infrastructure & Deployment

Docker (Integrated) -- docker-compose.dgx-spark.yml

Full stack deployment with all HCLS AI Factory services:

  • Milvus standalone + etcd + MinIO
  • 5 intelligence agents (including Cardiology)

Known Limitations

  1. Vector search requires running Milvus instance; agent degrades to LLM-only mode without it
  2. GDMT optimizer provides guidance only, not prescriptive orders
  3. Risk calculators use published coefficients; individual patient variation exists
  4. Cross-modal genomic triggers reference gene panels but do not execute genomic analysis
  5. Family screening protocols are informational; implementation requires institutional workflow
  6. FHIR R4 export covers core resources; full FHIR implementation would require additional profiling
  7. PDF generation requires wkhtmltopdf or equivalent system dependency
  8. Real-time event streaming requires persistent connection (SSE)
  9. PubMed/ClinicalTrials.gov ingest requires external API access
  10. Embedding model (BGE-small-en-v1.5) must be downloaded on first run (~130MB)
  11. EuroSCORE II uses simplified logistic regression; institutional calibration may improve accuracy
  12. MAGGIC score lookup tables are discretized to integer scores 0-50

Issues Found and Fixed

Issue Resolution Status
RiskScoreInput sex validator accepted uppercase Added .lower() normalization Fixed
ASCVD calculator missing age validation for < 40 or > 79 Added ge=40, le=79 on ASCVDRequest Fixed
