A 23- year- old woman with a history of dysmenorrheal associated with abdominal
cramping goes to her primary care physician because of a 1- year history of episodic
diarrhea and blood- streaked stools; symptoms have become more bothersome over
the past 4 weeks.
She reports loose stools with increasing amounts of blood and abdominal cramping
over the past 4 days. She reports no fever or chills. Her appetite has been poor for the

cigarettes daily for the past 5 years. Findings from the physical examination show a
definite and moderately tender 5-cm mass in the right lower quadrant of her abdomen.
No joint effusion or skin lesions are noted. Results from the stool studies are negative
for enteric pathogens, and the results from her blood work show mild anemia
(hemoglobin, 11.2 g/dL), with a normal metabolic panel and normal thyroidstimulating hormone levels. Radiographic findings demonstrate a 10-cm narrowing in

Department complaining of severe chest pain after climbing stairs at his
daughter’s house.
Diagnosis
A preliminary diagnosis of myocardial infarction is made.
1- Define Myocardial infarction
Myocardial infarction or “heart attack” is an irreversible injury to and eventual
death of myocardial tissue that results from ischemia and hypoxia.
2- What are the Manifestations of myocardial infarction
1. Severe chest pain and discomfort
2. Irreversible cellular injury
3. Release of myocardial enzymes such as creatine phosphokinase
(CPK) and lactate dehydrogenase (LDH) into circulation from myocardial
damaged cells.
4. Electrocardiogram changes
5. Inflammatory response from the injured myocardium — Leukocyte infiltration,
increased white blood cell counts, fever.
6. Coagulative necrosis of the area of the myocardium affected by the infarction.
7. Repair of damaged areas occurs by replacement with scar tissue and not functional
muscle tissue; therefore, some alteration in function is inevitable
2- What are the etiology of Myocardial infarction:

Most heart attacks are the direct Result of occlusion of a coronary
blood vessel by a lipid deposit.

Prolonged vasospasm might also precipitate a myocardial infarction in
certain individuals.
