Overview

Evaluation of exercise stress HFQRS accuracy for coronary microvascular dysfunction, indicating its diagnostic potential.

Key Points

  • Exercise HFQRS shows a moderate correlation with coronary microvascular dysfunction metrics.
  • The area under the ROC curve for predicting microvascular dysfunction reached 0.81, signifying good accuracy.
  • Sensitivity and specificity of HFQRS were found to be 0.686 and 0.971, respectively.
  • Multifactorial analysis identified positive HFQRS leads as an independent predictor of coronary microvascular resistance.
