Abbott Coronary Microvascular Dysfunction Algorithm

Kugwirizana kwa Catheter

(c)

• Sambani bwino 1
• Kugwirizana kwa Coaxial Guide 1
• Onetsetsani kuti palibe dampife 1
  

(A)

Advance Waya

• Funsani LAD pokhapokha ngati pali gawo linalake lofuna chidwi 2
• Mawaya anzeru sensa 2/3 disally mu chotengera 3
•  Yang'anirani GTN/NTG1
  

(T)

Nthawi Yopita Kupuma

• Flush/purge pre-Tmn rest kuti muchotse magazi aliwonse komanso kusiyanitsa 3
• Kutentha kwa chipinda 3
• Jakisoni wachangu 3 mL x 3 3
• Adilesi ogulitsa (± 0.25s) musanapitirire 4*
  * Bwerezani kuyeza kwa kupuma kwa Tmn
  

(H)

Hyperemic Transit Time

• Kuchepetsa hyperemia 5
• Tsimikizirani hyperemia*6
• Flush/purge pre-Tmn hyp kuchotsa magazi aliwonse komanso kusiyanitsa 6
• Kutentha kwa chipinda 6
• Jakisoni wachangu 3 mL x 3 6
• Otsatsa malonda (± 0.15s) musanapitirire 4 **
  * Kuchepetsa kupanikizika, zizindikiro za odwala, FFR kutsika *
  *Bwerezani kuyeza kwa Tmn hyp

(C)

Malo osungira a Coronary Flow (CFR)

• CFR <2.5*4
• CFR imvi zone 2.0-2.4*
  * Kukhazikika kogwirizana
  

(M)

Index of Microcirculatory Resistance (IMR)

• IMR ≥252
• Gwiritsani ntchito IMRcorr ngati FFR ≤0.807
  

(D)

Matenda

• Kuzindikira kwa CMD kutengera IMR ≥25 ndi CFR <2.5*2,4
• CFR imvi zone 2.0-2.4*
• Onani malangizo ndi chikalata chogwirizana2,4, 8-9
  * Kukhazikika kogwirizana
