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

Right atrium pressure (& what is considered high)?
✓✓~ No definition
anything over 8 mmHg
Right ventricle systolic pressure (& what is considered high)?
✓✓~ Pressure at the peak of systole
anything over 28 mmHg
Right ventricle end diastolic pressure (& what is considered high)?
✓✓~ Pressure at the end of diastolic, right before systole
anything over 9 mmHg
Left atrium pressure (& what is considered high)?
✓✓~ No definition
anything over 12 mmHg
Left ventricle systolic pressure (& what is considered high)?
✓✓~ Pressure at the peak of systole
anything over 140 mmHg
,Left ventricle end diastolic pressure (& what is considered high)?
✓✓~ Pressure at the end of diastole, right before systole
anything over 12 mmHg
Endocardium
✓✓~ Innnermost layer of the heart which comes in contact with the blood
Made of simple squamous epithelium and underlying connective tissue
Myocardium
✓✓~ This is the middle layer of the heart
Contains myocytes-which are responsible for heart contraction
Pericardium
✓✓~ The outermost layer of the heart
Made up of two layers
Fibrous Pericardium
✓✓~ Made of connective tissue and provides the heart with stability by connecting to the sternum
anteriorly and the diaphragm inferiorly
Serous pericardium
, ✓✓~ This has two layers that consist of the epicardium and the parietal layer
Epicardium
✓✓~ this is the visceral layer of the heart and it lays directly over the heart and contains the
coronary arteries
Parietal layer
✓✓~ Layer of the heart above the epicardium and underneath the fibrous pericardium
Left ventricle
✓✓~ -This ventricle is the larger of the two because its workload is greater
-This ventricle pumps blood to the entire body and has a much higher afterload to
push against
-This makes the pressure in this side of the heart greater than the other side
Right ventricle
✓✓~ -This ventricle only pumps blood into the lungs
-The pressure in this side of the heart is lower than the other side
Umbilical vein
✓✓~ This receives oxygenated blood from the placenta
It connects to the hepatic circulation but also connects to the inferior vena cava by
the ductus venosus
