No results posted yet for this study

Summary

1. To compare the risk of atherosclerotic lesion progression and subsequent patient-oriented composite outcomes (all-cause mortality, any MI, or any Ischemia-driven repeat revascularization) between deferred lesions with or without over microvascular disease, defined as physiological classification
2. To explore independent predictors of atherosclerotic lesion progression in deferred lesions based on fractional flow reserve-guided strategy and treated by contemporary medical treatment

Conditions

  • Ischemic Heart Disease

Interventions

DEVICE

Comprehensive physiologic evaluation

Comprehensive physiologic evaluation using pressure-temperature sensor wire to measure fractional flow reserve, coronary flow reserve, index of microcirculatory resistance

DEVICE

Intravascular imaging devices

Intravascular ultrasound or optical coherence tomography
