Hurmm...ary ni satu ag toturial yg bkaitan ngn Coronary Artery Disease. Iaitu pykit Myocardial Infarction (MI). actually ni sume utk ulgkji nur aje spya jd misi yg cmrlang satu ary nty. hehe...

Oke.. Let's start!

1. Berikan definisi MI?
 Necrosis dissuatu bhgian otot jntung yg dsbabkn oleh tptusny bklan drah akbat dr arteri koronari yang tsumbat dn mghlang bklan O2 dn nutrien ke myocardium.

2. Terangkan ciri-ciri kskitan MI.
a) Lokasi: sakit dada di substernal/ retrosternal.
b)ciri-ciri sakit

b)Nausea and vomitting
-Kskitan teruk mrgsg reflek mntah.
c)Demam
-suhu tinggi.dsbbkan:: necrosis tisu2 myocardium, pertambahan intracellular enzime, pngktan sel leukosit dlm proses inflamasi.
d) Oliguria
-Kurg urine output krn Acute Pulmonary Edema yg teruk, cardiogenic shock krn sudden renal shutdown.
e)Tanda vital
-Tachycardia- Gangguan fgsi contractility cardiac dn kprluan jntung mrgsg sistem saraf simpatetik utk tgktkan dyutan jntung
-pngktan BP-akbt prses inflammatory tisu myocardium yg necrosi.
-kmdian BP mnurub-akbt kurg cardiac output dr myocardium yg lmah dlm fgsi kuncupan.
-pngktan kdar pnfsan akbat sakit dn bmbang.
f) keadaan am pskit
-anxious, restless
-shortness of breath (sob)
-cyanosis-kurg bkln 02 sbb gngguan fgsi contractility cardiac.
-Letih, lmah sbb kurg bkln O2 dn nutrien ke tisu2
-Keliru,pucat,cemas- gngguan sis. simpatetik-mgurgkan cerebral perfusion.
