Sɔntɛnde yu kin gɛt smɔl pen na yu chɛst, ɔ yu kin fil fɔdɔm afta yu dɔn tray smɔl, ɛn wɔnda se, "Blɔk de na wan pan mi korona at?" We yu gɛt dɛn kayn dawt de, dɔktɔ kin aks yu fɔ mek dɛn du korona angiogram, we na tɛst we dɛn kin yuz fɔ put kateshɔn pan yu at. I kin chɛk fɔ ɛni blɔk ɔ stenɔsis na di korona at we de gi blɔd to di at. Bɔt sɔntɛnde, ivin afta yu dɔn si dis blɔk, i nɔ kin izi fɔ no if i siriɔs fɔ mek yu nid stent ɔ if yu kin kɔntrol am wit mɛrɛsin nɔmɔ. Dis na di say we dis spɛshal tɛst we dɛn kɔl Fractional Flow Reserve ɔ FFR de kam fayn.
Simply put, wetin na dis FFR?
Imajin se wata paip de, ɛn wan smɔl dɔti de stɔp na di midul pan di paip. Naw, di prɛshɔn we di wata we de flɔ tru di paip gɛt difrɛn smɔl bifo ɛn afta di paip blok, nɔto so? Di FFR tɛst de du sɔntin we fiba dis.
Fɔ tɔk am simpul wan, FFR na we fɔ no aw bɔku blɔd de flɔ to di at mɔsul we de ambɔg bikɔs wan pan yu korona at dɛn dɔn blok. Insay dis, dɛn kin mɛzhɔ blɔd prɛshɔn na ɔl tu di say dɛn we di blɔk de blo. We di dɔktɔ kɔmpia di tu prɛshɔn valyu dɛn, i go no if di blɔk rili ambɔg di at mɔsul ɔ nɔ ambɔg am.
dis tεst na wan minimally invasive prosidכs we dεn de du we dεn de du kadyak kateshכn.
Ustɛm dɛn nid fɔ du FFR tɛst?
Nɔto ɔlman nid dis tɛst. Bɔku tɛm, dɔktɔ go disayd fɔ du FFR tɛst pan dɛn tin ya:
- Intamεdiεt Blɔk dεm: If angiogram sho se blכk bitwin 50% εn 70% pan wan vein, i at fכ se fכ sכri if dεn nid stent. Insay dɛn kayn tin ya, di FFR kin mɛzhɔ ɛksaktɔli aw di blɔk de ambɔg di blɔd flɔ.
- We bɔku bɔku tin dɛn kin blok: Sɔntɛnde, pɔsin kin gɛt bɔku smɔl smɔl tin dɛn we kin blok na in veins. FFR kin ɛp fɔ no us blɔk de rili afɛkt di blɔd flɔ mɔ, we nɔ nid fɔ put stent insay ɛni wan pan dɛn.
- Afta dɛn dɔn put stent: Sɔntɛnde afta dɛn dɔn put stent, dɛn kin du FFR tɛst fɔ mek shɔ se i de wok fayn ɛn di blɔd dɔn kam bak to nɔmal.
Bɔt if di blɔk na wan vein nɔ rich 30% (we min se nɔ big blɔk nɔ de) ɔ pas 90% (we min se siriɔs blɔk de we rili nid tritmɛnt), bɔku tɛm dɛn nɔ nid fɔ du FFR tɛst. Bikɔs da tɛm de, dɛn kin disayd bɔt tritmɛnt frɔm di angiogram insɛf.
Wetin na di difrɛns bitwin FFR ɛn iFR?
Yu kin dɔn yɛri bak bɔt iFR (instant wave-free ratio). Dɛn tu tin ya de sho aw di vein blok bad bad wan. di men difrεns na dat, insay di FFR tεst, dεn kin gi wan spεshal mכg, lεk adenosine, fכ mek di bכdi fכ fכlכ pasmak na di at. Insay di iFR tɛst, instead fɔ gi dis kayn drɔg, dɛn kin mɛzhɔ di prɛshɔn na wan patikyula tɛm na di at bit. Yu dɔktɔ go disayd uswan pan dɛn tu we ya go fayn fɔ yu.
Aw yu fɔ pripia bifo di tɛst?
Yu dɔktɔ go gi yu sɔm spɛshal instrɔkshɔn dɛn bifo dis tɛst, ɛn i rili impɔtant fɔ fala dɛn.
- Infɔmeshɔn bɔt mɛrɛsin: Dɛn kin aks yu fɔ stɔp fɔ tek sɔm mɛrɛsin dɛn, mɔ di wan dɛn we de mek yu blɔd tan , sɔm dez bifo di tɛst. Mek shɔ se yu tɛl yu dɔktɔ bɔt ɔl di mɛrɛsin dɛn we yu de tek.
- Fɔ it ɛn drink: Dɛn go advays yu fɔ nɔ it ɔ drink ɛnitin afta midnayt di nɛt bifo di tɛst.
- Asisten: Bikɔs dɛn go anestez yu we dɛn de du di tɛst, i impɔtant fɔ mek yu gɛt pɔsin fɔ kɛr yu go na os afta di tɛst.
Wetin kin apin we dɛn de du di tɛst?
If yu jɔs du di FFR tɛst, i nɔ go tek 60 minit. Bɔt if yu disayd fɔ put stent wantɛm wantɛm bay di rizɔlt, i go tek smɔl tɛm. Di ɔl di prɔses de go lɛk dis:
1. Numbness: Fɔs, dɛn kin gi smɔl injɛkshɔn fɔ numbing mɛrɛsin na wan vein na yu an, groin, ɔ nɛk usay dɛn go put di kateshɔn.
.
3. Fɔ muv to di at: Dɛn kin tek tɛm gayd dis kateshɔn to di korona at na di at bay we dɛn de yuz ɛkstrem rayt (fluoroscopy) tɛknɔlɔji.
4. Day injεkshכn: nεks, dεn injεkt wan spεshal day (kכntrast mεdia) insay di vein dεm tru dis tכb. Dɔn yu kin si di insay pat pan di vein dɛn klia wan pan di ɛkstrem rayt.
5. Prɛshɔn Waya: Na dis say di rial wok kin bigin. wan waya we rili tכn wit sεns dεm de pas tru di kateshכn εn put am insay di vein we blכk.
6. Prɛshɔn mɛzhɔmɛnt: Dɛn kin yuz dis prɛshɔn waya fɔ mɛzhɔ blɔd prɛshɔn bifo ɛn afta di vein dɔn blok.
7. Fɔ gi mɛrɛsin:Fɔ mek yu rid di rayt we, yu nid fɔ mek di blɔd go na yu at mɔ. Fɔ dis, dɛn go gi yu wan mɛrɛsin we dɛn kɔl adenosine. We dɛn gi yu dis mɛrɛsin, yu kin gɛt smɔl pen na yu chɛst ɛn i kin at fɔ blo fɔ lɛk wan minit so. Dis na nɔmal tin, nɔ wɔri. Dis min se di mɛrɛsin de wok ɛn naw na di rayt tɛm fɔ tek di ridin.
8. Disishɔn fɔ di tritmɛnt: Afta yu dɔn gɛt di FFR valyu, di dɔktɔ go disayd if yu nid fɔ put stent ɔ nɔ nid fɔ put yu stent. If nid de, dɛn kin put di stent wantɛm wantɛm afta dɛn dɔn du angioplasty.
9. Ɛnd: We dɛn dɔn fɔ du di wok, dɛn kin pul di kateshɔn, dɛn kin put prɛshɔn na di say we dɛn put am, ɛn put plasta.
Aw fɔ ɔndastand di tin dɛn we kin apin?
Di rizulyt fɔ di FFR tɛst de kam insay wan nɔmba. Dis nɔmba rili izi fɔ ɔndastand.
| FFR Rizult | Wetin i min? |
|---|---|
| 0.94 to 1.0 (nɔmal) . | Rili! Di blɔd we de flɔ na yu at rili fayn. di blɔk we wi kin si na di at nɔ de mek ɛni big prɔblɛm pan di blɔd flɔ. Bɔku tɛm, dɛn nɔ kin nid fɔ put stent, ɛn dɛn kin ebul fɔ kɔntrol dis sik wit mɛrɛsin. |
| If i smɔl pas 0.80 | insay dis kes, di bכdi we de fכlכ to di at mכsul dεn dכn rεdכks bכku bכku wan bikɔs di at de sכmtεm sכmtεm. Di dɔktɔ kin disayd fɔ du tritmɛnt lɛk fɔ put stent (angioplasty). |

Wetin fɔ ɛkspɛkt afta di tɛst?
Big big kɔmplikeshɔn dɛn nɔ kin apin afta dɛn dɔn du FFR tɛst.
- We yu de go na os:If dɛn nɔ put stent, yu go ebul fɔ go na os afta yu dɔn wach am fɔ sɔm awa. If dɛn put stent, yu go nid fɔ de na ɔspitul da nɛt de.
- Rɛst: I bɛtɛ fɔ rɛst fɔ wan ɔ tu dez afta yu dɔn go na os. Sɔm brus ɛn sɔri kin de usay dɛn put di kateshɔn.
- Di sayd ɛfɛkt dɛm: Tin dɛm lɛk chɛst pen we di adenosine mɛrɛsin kin kam wit go dɔn kpatakpata insay sɔm minit.
If yu gɛt dɛn sik ya, kɔl yu dɔktɔ wantɛm wantɛm.
If yu gɛt ɛni wan pan dɛn sik ya afta yu dɔn go na os frɔm di tɛst, tɛl yu dɔktɔ wantɛm wantɛm. If nid de, go na di Imejɛnsi Dipatmɛnt (ETU) na di ɔspitul we de nia yu.
- Bɔrku pen na yu chɛst
- I nɔ kin izi fɔ yu fɔ blo
- Fiva
- Blɔd, swel, ɔ bad bad pen na di say we dɛn put kateshɔn
- Diziz we pɔsin kin gɛt
- Abnɔmal chenj dɛn na di at rit (palpitations) .
FFR na wan rili impɔtant tɛst fɔ trit at sik. I kin ɛp dɔktɔ dɛn fɔ no aw di vein blok bad bad wan, nɔ put stent we nɔ nid fɔ put am, ɛn pik di bɛst tritmɛnt fɔ yu, pas fɔ abop pan wetin dɛn kin si pan angiogram nɔmɔ. So, if yu dɔktɔ tɛl yu fɔ du dis tɛst, nɔ fred fɔ aks ɛni kwɛstyɔn we yu go gɛt.
Mɛsej we dɛn kin kɛr go na os
- FFR (Fractional Flow Reserve) na spɛshal tɛst we de sho aw di at at at blɔk kin tranga .
- dis rili imכtant fכ no if stent nid fכ intamεdiεt lεvεl (50%-70%) blכk we dεn si pan angiogram.
- dis tεst de du we dεn de du kadyak kateshכn.
- If di rizɔlt nɔ rich 0.80, i de sho se di blɔk de mek di blɔd nɔ de flɔ bɔku ɛn i kin nid fɔ gɛt tritmɛnt.
- Dis tɛst de mek dɔktɔ dɛn nɔ ebul fɔ put stent we nɔ nid fɔ put am ɛn gi di tritmɛnt we fit di pɔsin.
