(A)

Mohala o tsoetseng pele

• Botsa LAD ntle le haeba ho na le sebaka se itseng sa thahasello 2
• Sensor ea terata e tsoetseng pele 2/3 ka har'a sekepe sa 3
•  Laola GTN/NTG1
  

(T)

Nako ea ho Tsamaea nakong ea Phomolo

• Flush/purge pre-Tmn phomolo ho hlakola mali leha e le afe le phapang 3
• Mocheso oa mocheso oa kamore 3
• Matla a 3 mL x 3 liente 3
• Aterese barekisi ba kantle (± 0.25s) pele u tsoela pele 4*
  * Pheta tekanyo ea phomolo ea Tmn
  

(H)

Hyperemic Transit Nako

• Hlahisa hyperemia 5
• Netefatsa hyperemia*6
• Flush/purge pre-Tmn hyp ho hlakola mali leha e le afe le phapang 6
• Mocheso oa mocheso oa kamore 6
• Matla a 3 mL x 3 liente 6
• Aterese barekisi (± 0.15s) pele u tsoela pele ka 4**
  * Ho fokotseha ha khatello, matšoao a mokuli, ho theoha ha FFR *
  * Pheta tekanyo ea Tmn hyp

(C)

Coronary Flow Reserve (CFR)

• CFR <2.5*4
• CFR grey zone 2.0-2.4*
  * Khokahano e tsoelang pele
  

(M)

Index of Microcirculatory Resistance (IMR)

• IMR ≥252
• Sebelisa IMRcorr haeba FFR ≤0.807
  

(D)

Tlhahlobo

• Tlhahlobo ea CMD e thehiloeng ho IMR ≥25 le CFR <2.5*2,4
