`Coronary Flow Reserve (CFR)` tih hi eng nge ni? A awlsam zawngin...

I thinlung hi car engine angin ngaihtuah rawh. A kal dan pangngaia a kal chuan engine hian fuel engemaw zat a mamawh a ni. Mahse, tlang i chhoh dawn emaw, chak taka i kal dawn emaw chuan engine hian fuel a mamawh tam zawk a ni lawm ni? Chutiang chuan kan thinlung chu a ni.
