STEMI Flashcards
Mechanism of STEMI
If
after STEMI:
If EF <40% + HF:
ACE-In
Or
Arbs (if w Acei contraindications)
Ventricular remodeling with overall chamber enlargement is riskier when greAter dilation is located at
Anterior wall
Apical LV wall
Primary cause of IH HOSPITAL DEATH
PUMP FAILURE
Most common clinical signs of pump failure
Rales
S3 and S4 gallop sounds
Mortality rate of KILLIPS class I no signs of pulmonary or venous congestion
0-5%
Mortality rate of KILLIPS class II MODERATE HF (basal rales, S3, tachypnea or signs of RV failure : venous and hepatic congestion)
10-20%
Mortality rate of KILLIPS class III
Severe heart failure
Pulmonary Edema
35-45%
Mortality rate of KILLIPS class IV: Shock with sbp <90mmhg + SSX of peripheral vasoconstriction, cyanosis, mental confusion and oliguria
85-95%
What is the extent of infaction if with hemodynamics evidence of abnormal global LV function
20-25%
What is the extent of infaction if with cardiogenic shock ?
More than or equal to 40%
If with INCREASED LV filling pressure >22mmhg and Normal cardiac index (2.6 x 3.6 L/(min/m2))
Give DIURETICS
