• Required Specifics:

  • Vessels involved (single, double, triple)

  • Whether native arteries or grafts are affected

  • Timing and pattern of anginal pain

  • Any precipitating factors

• Supporting Elements:

  • Relevant diagnostic tests (stress test, cardiac cath)

Scribing.io Automation

The AI scribe automatically:

• Identifies language describing coronary disease ("atherosclerosis," "CAD," "coronary disease")

• Tags anginal symptoms descriptions

• Flags when specific angina type is missing

• Prompts for additional specificity when documentation is insufficient

• Cross-references with cardiac medications and diagnostic studies
