Question

Schematic diagram pathophysiology of Non St elevation MI ,Aortic dissection and pericarditis

Answer 1

Answer:- NON ST MYOCARDIAL INFARCTION

PATHOPYHSIOLOGY

Myocardial ishcemia will decrease myocardial oxygen supply and / or increased demand.

In majority of the cases , NSTEMI is due to sudden decrease in blood supply via partial occlusion of the affected vessels.

Answer :- pericarditis patho physiology

When pericardial cell injury due to any etiological factor then injured cell release some combination of fluid and cells in an inflammatory response,

Which leads to fever as well as the serofibrous exudate roughness the 2 layers creates friction between them, pericardial friction rubs occurs due this condition irritatation and inflammation of the surroundings pleura and diaphragmatic tissue which leads to pain.

Answer:- Arotic dissection patho physiology

An aortic dissection happens due to tears appear in the inner lining of the arota,

Which is the main artery leaving the heart. Blood surges into the tears, cause the aorta lining to split, or dissect .

when stroke volume increase pressure on aorta which attaches with left ventricle blood create pressure on aorta leads to rupture or dissection of aprta
