A chang chuan hla vak lo i kal lai pawhin thawk harsa i ti em? A nih loh leh i ke a hring a, i chau mai mai em ni? Hetiang symptoms i neih chuan i doctor chuan thisen test BNP tih a rawt thei ang. Mi tam tak chuan he hming an hriat hian an hlauthawng deuh thin a, a chhan chu eng nge a nih chiah an hriat loh vang a ni. Mahse, eng nge ni tak tak? Eng nge a detect? Heng zawng zawng hi awlsam takin, i hriatthiam theih angin i sawi ang u.
BNP hi eng nge ni tak tak?
A awlsam zawngin BNP hi i thinlung atanga protein siam a ni. BNP hi B-type Natriuretic Peptide tihna a ni. Mahse mi thenkhat chuan "Brain" Natriuretic Peptide an ti bawk. Chu chu scientist ten he protein hi thluak tissue ah an hmuhchhuah hmasak vang a ni. Mahse a hnuah chuan kan thinlung atanga siam a ni ber tih hriatchhuah a ni a, a bik takin left ventricle atanga siam a ni.
Hetiang hian han ngaihtuah teh. I thinlung chu pump ang mai a ni a, a thawk chhunzawm zel a ni. A chang chuan he pump hian hna a thawh nasa zawk a ngai thin. Chumi awmzia chu heart muscle chu a inzawm tan tihna a ni. Hetiang hunah hian thinlung hian he protein BNP an tih hi thisenah a chhuah tir thin.
Heng BNP te hian thil mak tak tak an ti thei a ni:
- Kidney te chu signal an pe a, "Taksaah hian chi leh tui tlem a tam lutuk a, chuvangin zun hmangin paih bo rawh," an ti.
- Thisen kalna kawngte chu "tlem inhawng (dilate) turin a hrilh bawk a, thisen chu awlsam zawkin a luang chhuak thei a ni."
Heng thil pahnihte hian thisen sang a tihhniam bakah thinlungin thisen a pump tur zat a tihhniam bawk. Hei hian thinlunga hna thawh tur a ti tlem a, chu chu a thawhrim a ngai tihna a ni. Chuvangin BNP hi thinlung puitu thian ang mai a ni.
Mahse, i thisena BNP level chu a tlangpui aia sang zawk a nih chuan i doctor hnenah signal pawimawh tak a pe a ni. Chu chu, "I thinlung chu a buai lutuk a ni" tihna a ni. Hetiang dinhmun hi heart failure-ah hmuh tur a awm fo.
Lab thenkhatah chuan hetiang test hi NT-proBNP tih hi an ti thin. An pahnih hian information inang an pe a, mahse normal range erawh a danglam thung.
Engvangin nge doctor chuan he BNP test hi a rawt ang?
I doctor-in he test hi a rawt chhan hrang hrang a awm thei.
- Lung chak lohna chhinchhiahna i neih chuan: Thâwk harsa, hah reng, ke leh ke ruh hring hring ang chi i neih chuan he test hi a chhan chu thinlung lam harsatna nge lung lam harsatna a nih leh nih loh hriat chian a pawimawh hle.
- Lung natna i neih tawh chuan: Lung natna i nei tih hmuhchhuah tawh i nih chuan he test hian a nasat dan tehna atan a pui a ni.
- Enkawlna a hlawhtling em tih en rawh:He BNP level hi i damdawi pek hian i thinlung a pressure a tihziaawm em tih leh treatment plan a thawk tha em tih enfiah thin a ni bawk.
- I hlauhawm a nih chuan: Lung natna vei theihna i nei sang a nih chuan (entir nan, zunthlum emaw thisen sang emaw ang chi natna nei) i thinlung hriselna hriat theihna turin he test hi tih theih a ni bawk.
He thisen test hi engtin nge an tih? Hlauh tur thil a ni em?
Hei hi a awlsam hle. Hlauh chhan tur i nei lo. Hei hi thisen lak dan pangngai ang bawkin tih a ni.
Nurse emaw doctor emaw chuan i kut a vein pakhat a tifai ang a, needle te tak te a dah ang a, thisen tlem a la ang. Needle i dah hian stinging sensation tlem i nei thei a, mahse second tlemte chauh a daih ang.
Thisen an lak zawh chuan plaster emaw bandage te tak te chu a hmunah an hnawih thin. A hmun chu a hring deuh a, a sen deuhin a lang thei a, mahse hei hi ni khat emaw ni hnih emaw chhungin a bo vek ang. Chumi hnuah i thisen sample chu laboratory-ah thawnin i BNP emaw NT-proBNP level emaw a teh ang.
Hei hi test awlsam tak, rang tak leh him tak a nih avangin hlau suh.
Results hmuh theih nan eng chen nge hun a duh?
Hei hi he test thatna lian ber pakhat a ni. A result chu a rang thei hle.
Emergency avanga Emergency Department (ETU)-a admit i nih chuan, thawk harsatna ang chi, he result hi minute 15 chhung chauhvin i hmu thei tlangpui . Hei hi doctor-te tan emergency-a thutlukna siam thuai theihna tura puihna tha tak a ni.
Mahse, thinlung natna i neih tawh a, he test hi i tih fo a nih chuan, i enkawlna kal zel dan enfiah nan ni khat emaw ni hnih emaw a la ngai thei a, result a lo lang leh thei a ni.
BNP result hi engtin nge kan hrilhfiah ang? ‘Normal’ level chu eng nge ni?
Hei hi mi tam takin zawhna an neih a ni. Hetiang table-ah hian heng test pahnih average value hi han en ila.
| Test neihna tur hming | Kum hrang hrang | Normal level a ni |
|---|---|---|
| BNP | Mi zawng zawng hnenah | 100 pg/mL aia tlem lo |
| NT-proBNP a ni | Kum 75 hnuai lam | 125 pg/mL aia tlem lo |
| Kum 75 chunglam a ni | 450 pg/mL aia tlem lo |
Mahse hei hi hre reng ang che. Heng hlutnate hi kaihhruaina tlangpui chauh a ni. Heng ‘normal’ value te hi i kum, damdawi lam dinhmun dang, leh a chang chuan taksa rih zawng (obesity) a zirin a danglam deuh thei bawk. Chuvangin, i doctor chauhvin i result dik takin a hrilhfiah thei ang. Mahni thutlukna siam turin internet-ah innghat suh.
BNP level chu ‘Normal’ aiin a sang zawk a nih chuan eng nge a awmzia?
BNP level sang hian thinlungah harsatna engemaw zat a awm tih a tilang fo thin. BNP value 100 pg/mL aia tam a nih chuan heart failure chhinchhiahna a ni thei.
A tlangpuiin BNP hlutna a san poh leh thinlung hnathawh a harsa zual thin.
Mahse, BNP level sang chhan chu heart failure a ni ngai lo. He level hi hriselna lama harsatna dang vangin a sang thei bawk. Chuvangin he test ringawt atang hian thutlukna lian tak tak siam suh.
BNP level sang zawk thlen thei chhan dangte chu:
- Chronic Kidney Disease: Kal hnathawh that loh chuan thisenah BNP level a sang thei a, a chhan chu taksain tha taka a paih chhuah theih loh vang a ni.
- Lung natna dang: Lung natna bakah hian thinlung natna dang dangah pawh BNP a sang thei bawk.
- Lung lama harsatna: BNP level pawh hi lung chhunga thisen zam (pulmonary embolism) emaw, lung chhunga thisen sang (pulmonary hypertension) emaw ang chi dinhmun avang hian a sang thei bawk.
A result chu ‘Abnormal’ a nih chuan eng nge thleng leh ang?
I BNP level a sang chuan i doctor chuan puzzle pakhat chauh a ngai ang. A thlalak kimchang a hmuh theih nan test tam zawk a tih a ngai dawn a ni.
Entirnan, i doctor chuan hetiang test hi a rawt thei ang:
- Electrocardiogram (EKG): Thinlung electric hnathawh dan a enfiah thin.
- Echocardiogram: Thinlung scan a ni. Hei hian thil tam tak a check thei a, chu chu thinlung pump theihna leh a valve dinhmun te hi a ni.
- Chest X-ray: A rilru a buai em em a, a rilru a hah em em bawk a.
I doctor chuan heng test result zawng zawng te, i symptoms te, leh i medical history te hi a ngaihtuah vek ang a, thutlukna hnuhnung ber siam turin. Chumi hnuah chuan i tana ṭha ber tur enkawlna ruahmanna a siam ang.
Results chungchanga zawhna i neih chuan doctor zawh hreh suh. "Doctor, ka BNP level a sang tih min hrilh a, chu chu eng nge a awmzia tak?" tih hi i zawh theihna tur a ni.
Take-Home Thuchah a ni
- BNP test hi thisen test awlsam tak a ni a, i thinlung hriselna chungchang, a bik takin heart failure chungchang hriat tur pawimawh tak tak a pe a ni.
- Hetiang tih hi hlauh tur a awm lo. Thisen test pangngai ang mai a ni.
- BNP level sang chuan heart failure a kawk ngai lo. A chhan dang, kal natna ang chi te pawh a inrawlh thei bawk.
- I test result atanga thutlukna siamah zuang lut suh. Chumi chungchang chu i doctor nen inbia fo ang che.
- He test hi i doctor tan chuan dik taka a hriat theih nan leh enkawlna tha ber a pek theih nan a pui hle a ni.
