PCW >18 mmhg; CI < 2.2
Correct Answer
D. PCW >18 mmhg; CI < 2.2Explanation
Patients wiht cardiogenic shock due to a MI have low CO due to left ventricular dysfunction, also resulting in low CI. The LV's inability to pump forward causes pooling of the blood in the pulmonary circulation, resulting in high PCW.
