A chang chuan i rilru a na tlem a, a nih loh leh i thawhrimna tlem hnuah i rilru a hah a, "Ka coronary artery pakhatah blockage a awm em?" Chutiang rinhlelhna i neih chuan doctor chuan coronary angiogram tihsak turin a ti thei che a, chu chu cardiac catheterization hmanga test a ni. Heart-a thisen petu coronary arteries-a blockage emaw stenosis emaw a awm leh awm loh a enfiah thei a ni. Mahse a chang chuan he blockage hi hmuh hnuah pawh stent mamawh khawpa na a nih leh nih loh leh damdawi chauh hmanga control theih a nih leh nih loh chiang taka hriat a harsa thin. Hei hi he test bik Fractional Flow Reserve emaw FFR emaw tih hi a tangkai hle.
A awlsam zawngin, he FFR hi eng nge ni?
Tui pipe a awm a, chu pipe lai takah chuan bawlhhlawh tê tak tê a inkhung ang tih han ngaihtuah teh. Tunah chuan pipe atanga tui luang chhuak pressure hi a block hma leh a block hnuah a danglam deuh deuh a ni lawm ni? FFR test pawh hian chutiang bawk chu a ti ve tho.
A awlsam zawngin sawi ila, FFR hi i coronary artery pakhata blockage avanga heart muscle-a thisen kal zat a tihkhawtlai dan tehna hmanrua a ni. Hetah hian blockage sir lehlamah thisen sang teh a ni. Pressure value pahnih tehkhin hian doctor chuan blockage hian heart muscle a tichhe tak tak em tih a hre thei a ni.
He test hi minimally invasive procedure a ni a, cardiac catheterization laiin tih thin a ni.
Engtikah nge FFR test hi a ngai?
Mi zawng zawng hian he test hi an mamawh vek lo. Doctor chuan a hnuaia thil awm danah hian FFR test tih a rel tlangpui ang:
- Intermediate Blockages: Angiogram-ah hian vein 50% leh 70% inkar blockage a awm a nih chuan stent hman a ngai em tih chiang taka sawi a harsa hle. Chutiang hunah chuan FFR hian blockage hian thisen kal dan a tikhawlo tih chiang takin a teh thin.
- Blockage tam tak a awm chuan: A châng chuan mi pakhatin a thisen kalnaah blockage tenau tam tak a nei thei bawk. FFR hian eng blockage nge thisen kal dan tibuaitu tak tak tih a hriat theih nan a pui thei a, stent pakhat zel ah stent dah ngai lovin.
- Stent dah hnuah: A chang chuan stent dah hnuah FFR test neih a ni thei a, chu chu a thawk tha em tih leh thisen kal dan pangngai a lo kir leh tawh em tih hriat chian a ni.
Mahse, vein pakhata blockage chu 30% aia tlem (blockage lian tham a awm lo tihna) emaw 90% aia tam (blockage na tak a awm tihna a ni a, enkawl ngai ngei tur a nih chuan) FFR test hi a ngai lo tlangpui. A chhan chu chutih lai chuan enkawlna chungchangah thutlukna siam theih a ni a, chu chu angiogram atang ngeiin a ni.
FFR leh iFR hi eng nge an danglamna?
iFR (instant wave-free ratio) tih pawh i hre tawh mai thei. Heng pahnih hian vein pakhata blockage nasat dan an teh a ni.
