• Iva nechokwadi chokuti hapana damping1
  

(A)

Advance Wire

• Bvunzurudza LAD kunze kwekunge paine nharaunda yekufarira 2
• Advance waya sensor 2/3 kureba mumudziyo 3
•  Tonga GTN/NTG1
  

(T)

Nguva Yekufambisa Pakuzorora

• Flush/purge pre-Tmn zorora kujekesa chero ropa uye musiyano 3
• Tembiricha yekamuri saline 3
• Brisk 3 mL x 3 jekiseni 3
• Kero kunze (± 0.25s) usati waenderera 4*
  * Dzokorora kuyerwa kweTmn kuzorora
  

(H)

Hyperemic Transit Nguva

• Kukonzera hyperemia 5
• Simbisa hyperemia*6
• Flush / purge pre-Tmn hyp yekubvisa chero ropa uye musiyano 6
• Tembiricha yekamuri saline 6
• Brisk 3 mL x 3 jekiseni 6
• Kero kunze (± 0.15s) usati waenderera 4 **
  * Kudzikira mukumanikidzwa, zviratidzo zvevarwere, FFR inodonha *
  *Dzokorora kuyerwa kweTmn hyp

(C)

Coronary Flow Reserve (CFR)

• CFR <2.5*4
• CFR grey zone 2.0-2.4*
  * Kuchinja kubvumirana
  

(M)

Index yeMicrocirculatory Resistance (IMR)

• IMR ≥252
• Shandisa IMRcorr kana FFR ≤0.807
  

(D)

Kuongororwa

• Kuongororwa kweCMD kunobva paIMR ≥25 uye CFR <2.5*2,4
• CFR grey zone 2.0-2.4*
• Tarisa kune nhungamiro uye gwaro rekubvumirana2,4, 8-9
  * Kuchinja kubvumirana
