STEMI

Question 1

Criteria for myocardial infarction?

Answer 1

Evidence elevated trop I values at least 1 value above the 99th percentile upper reference limit (URI).

Question 2

Criteria for acute myocardial Infarction?

Answer 2

Acute myocardial injury with clinical evidence of acute myocardial ischemia and with detection of a rise and/or fall of cTn values with at least one value above the 99th percentile and at least one of the following:

• Symptoms of Myocardial Ischemia
• New ischemic ECG changes
• Development of pathologic Q wave
• Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality in a pattern consistent with an ischemic etiology.
• Identification of a coronary thrombus by angiography or autopsy.

Answer 3

6 to 12 hours

Question 4

Levign Sign

Answer 4

Sign of massage or clutch their chests and frequently describe their pain with a clenched fist held against the sternum.

Question 11

One of the most important predictors of mortality following STEMI

Answer 11

Left ventricular dysfunction

Question 12

Criteria for cardiogenic shock

Answer 12

• frank or relative hypotension ( systolic BP < 80 or 90 mm Hg or a reduction in MAP of 30 mm Hg.
• inadequate cardiac index ( < 1.8 L/min/m2 without mechanical or pharmacological support or less than 2.2 L/min/m2 with support.
• elevated end diastolic pressures on the right ( > 10 to 15 mm Hg) and/or left ( > 18 mm Hg) side of the heart.
Evidence of end-organ hypoperfusion.
