I thinlung thisen kalna kawngkhar (blockage) hi engtiang chiahin nge a nasat? (Fractional Flow Reserve - FFR) Test hmangin i hre chhuak ang u!

Lung natna i neih i ringhlel em? A nih loh leh i doctor chuan i coronary arteries blockage a sawi tawh em? He test hi Fractional Flow Reserve, a tawi zawngin FFR tih hi i hre tawh mai thei. Hming buaithlak tak angin ri mah se, fiahna pawimawh tak a ni. Chuvangin, vawiin hian Sinhala tawng awlsam leh hriatthiam theih tak hmangin i sawi dawn nia.

Fractional Flow Reserve (FFR) hi eng nge ni?

A awlsam zawngin, (FFR) hi stenosis nasat dan dik tak tehna hmanrua a ni a, chu chu thisen kal dan a tikhawtlai em tih tehna hmanrua a ni a, chu chu i thinlunga thisen petu coronary arteries hmun dangah blockage a awm a nih chuan a ni. Tui pipe a inkhar chuan tui tlan chakna leh a pressure a tlahniam tih han ngaihtuah teh, a dik em? Chutiang bawkin coronary artery a block chuan a chhunga thisen luang chhuak pressure a tlahniam a ni. He (FFR) test hian a tih chu chu pressure difference chu a teh a, blockage chu engzat nge a nih tih chiang takin a zawng chhuak thin.

Doctor-te chuan he (FFR) test hi cardiac catheterization emaw coronary angiogram emaw an tih laiin an ti tlangpui. He test result hian eng ang enkawlna nge i dawn tur tih hriat theih nan a pui a ni (entir nan, damdawi chauh emaw, angioplasty leh stent emaw i hman tur nge). Hei hi fiahna pawimawh tak a ni a, thutlukna pawimawh tak siam turin a pui thei che a ni.

Engtikah nge FFR test hi a ngai?

Mi zawng zawng hian he test hi an neih a ngai dawn lo. Doctor chuan he (FFR) test hi special case tlemteah tih a rel ang.

• I coronary arteries imaging-ah chuan artery diameter 50% leh 70% inkar a block (stenosis) a nih chuan, he (FFR) test hian chu blockage chuan thisen kal dan a tikhawlo tak tak tih chiang takin a hre thei a ni.
• A châng chuan, thisen kalna kawng 90% vêlah blockage nasa tak awm mah se, a nasatzia dik taka tehna atan he test hi tih a ni.

Mahse, i artery blockage chu 30% aia tlem emaw, 70% aia tam emaw a nih chuan he (FFR) test hi a ngai lo tlangpui. A chhan chu blockage a tlem hle (30% aia tlem) a nih chuan enkawlna (angioplasty ang chi) a ngai lo mai thei. Blockage a lian hle (70% aia tam) a nih chuan enkawl a ngai tak zet a ni. (FFR) hian a tih chu chutiang in-between situation-ah chuan thutlukna dik siam tura puih a ni.

Pawimawh: Tun hmaa angioplasty leh i artery-a stent dah i neih tawh chuan he (FFR) test hian nakin lawkah heart attack lian tak i neih theih dan tur a hrilhfiah thei bawk.

He (FFR) test hian chhiatna a nei em?

Medical test apiang ang bawkin thil tenawm tak tak ngaihtuah tur a awm.

• A châng chuan, false normal result a awm thei bawk. Hei hian harsatna a awm tak tak tihna a ni a, mahse test hian a hmuchhuak lo mai thei. Chutianga a lo awm theih chhan pakhat chu i thisen kalna kawng te tak te (coronary arterioles) te hian i thisen kalna kawng zau zawka i test laiin damdawi i pek chu an chhang tha lo a nih chuan a ni.
• Tin, vein chhunga narrowed area sei zawng hian FFR value a nghawng bawk.

I doctor hian heng zawng zawng hi a hriat chian em avangin heng zawng zawng hi a ngaihtuah hnuah thutlukna a siam ang.

(iFR) leh (FFR) hi eng nge ni? An pahnih inthlauhna chu eng nge ni?

(iFR) tih hi i hre tawh mai thei. (iFR) tih hi (instant wave-free ratio) tihna a ni. (FFR) leh (iFR) te hi thinlung thisen kalna kawng (arteries)-a blockage nasat dan tehna test an ni. Mahse a danglamna tlem a awm.

• (FFR) test neih chhung hian: Thisen kalna kawng tizau tur leh thisen kal chakna tur damdawi bik, adenosine (Adenocard® emaw Adenoscan®) pek thin a ni.
• (iFR) test-ah: Chutiang damdawi hman loh chuan thinlung cycle chhunga hun bik takah pressure chu teh a ni.

An pahnih tum chu inang mah se, an tih danah hian danglamna tlem a awm. I doctor chuan eng nge i tan a tha ber tih a rel ang.
