ST Elevation Myocardial Infarction (STEMI) ~ Myocardial infarction which results from a thrombus permanently lodging in the vessel which results in the progression of the myocardial infarction to include the entire thickness of the ventricular wall Cardiac Troponins ~ Very reliable way to diagnose MI -Can be detected in 2-4 hours after onset of pain and should be monitored -They peak at 24 hours and disappear within 7-10 days Myocardial ischemia ~ This is marked by T wave inversion ...

PCCN questions with 100% correct answers Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) - Correct Answer ️️ -A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open ar...

Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) - A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known as coronar...
