1. Blood supply of the heart

2. Histology

   • Elastic Arteries
   • Muscular Arteries
   • Arterioles
   • Capillaries
   • Venules
   • Veins
   • From heart to tissues

3. He had

   • Retrosternal chest pain
     • Causes include: Gastrointestinal problems, Respiratory problems, Cardiac problems, & Tumors
     • Radiating

4. Angina

   • chest pain <20 min caused by reduced blood flow to the heart

5. Investigations

   • Blood test
     • For cardiac enzymes, ESR, WBC, glucose
   • ECG
   • Lipid profile

6. Myocardial infarction

   • is the irreversible death (necrosis) of heart muscle secondary to prolonged ischemia
   • Signs & symptoms
     • Typical intense chest pain for >20 min
   • classification
     • Subendocardial
       • NSTEMI
     • Transmural
       • STEMI
   • Complications
     • Arrhythmia
     • Heart failure
     • Cardiogenic shock
       • Is a condition in which a suddenly weakened heart isn't able to pump enough blood to meet the body's needs.
       • Signs & symptoms
         • • Hypotension • Absence of hypovolemia • Tachycardia • Clinical signs of poor perfusion
   • pathogenesis
   • Surgical management
     • Angioplasty
       • Percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive procedure to open up blocked coronary arteries, allowing blood to circulate unobstructed to the myocardium.

7. Pharmacological management

   • -nitrate -beta blocker or CCBs -aspirin -Oxygen -(ACE) inhibitors -Revascularization
