CVS: Acute Coronary Syndrome/ Myocardial Infarction (MI)

982 S & Sx of acute MI.

983 The common mechanism to all ACS (STEMI, NSTEMI, unstable angina) is r..... or erosion of the fibrous c..... of a coronary artery p..... This leads to platelet aggregation and adhesion, localized t....., vasoconstriction and distal thrombus embolization. Thrombus formation and the v..... produced by platelet release of serotonin and thromboxane A2, results in myocardial i..... due to reduction of coronary b..... f.....

986 What are two key questions in determining Rx/Mx of ACS?

986 Describe the immediate Mx of a pt with STEMI.
