Overview
Sensitivity and Specificity
When compared to reversible defects on myocardial perfusion imaging, a coronary flow reserve less than two has:
- Sensitivity of 86 to 92% and a specificity of 89 to 100%. The predictive accuracy is 89 to 96%, the positive and negative predictive values are 84 to 100% and 77%5 to 95%.
Complications
The risk of intracoronary Doppler velocity wire measurements are as follows (n=906):
- Bradycardia: 1.7%
- Coronary spasm: 2%
- Ventricular fibrillation: 0.2%
