How It Works:

  • Follow fasting, coffee avoidance, and nuclear stress test prep recommendations.
  • A radioactive tracer aids in blood flow visualization.
  • Lexiscan Injection: The medication stimulates cardiac activity like that of exercise.
  • Imaging: Before and after stress, a specific camera records cardiac pictures.
