BNKN602 EXAM SCRIPT 2025/2026 QUESTIONS AND
SOLUTIONS GRADED A+ TIP
✔✔Progression of MI - ✔✔Ischaemia present @ onset (cause)
Injury present 20-40min after onset
10% infarction present 30mins after onset
100% infarction present 24hrs after onset
✔✔ACS/MI diagnosis - ✔✔Hx chest pain & related symptoms
12 lead ECG - ST elevation height & area of 💙
Blood tests; troponin T & I, cardiac enzymes: CK-MB
✔✔Blood tests for MI/ACS diagnosis - ✔✔-Troponin T&I - cardiac specific enzymes
-Cardiac enzymes: creatinine kinase (CK-MB)
-Electrolytes; k+ NA+ important for electrical conduction & kidney
-Full blood count
-Lipid profile (fasting)
-Brain Naturide Peptide
-Creatinine clearance time (renal impairment - dosing)
-CRP ; inflammation
✔✔ACS/MI diagnostic investigations - ✔✔Coronary Angiogram +/- angioplasty
Electrophysiological studies
Echocardiography
Exercise tolerance test
✔✔Priority goals in management of ACS/MI - ✔✔Open the artery and keep it open
✔✔STEMI - ✔✔ST elevation myocardial infarction
✔✔NSTEMI - ✔✔Non-ST segment evaluation myocardial infarction
✔✔Define STEMI - ✔✔Complete obstruction of a major coronary artery
Full thickness damage of ❤️ muscle
✔✔Define NSTEMI - ✔✔Complete obstruction of a minor coronary artery, or a partial
occlusion of a major CA
Causes partial thickness damage of ❤️ muscle
✔✔Define ❤️ failure - ✔✔Hearts inability to consistently pump enough blood to organs
and tissues
Cardiac output > metabolic demands of body : accommodate venous return
✔✔Systole - ✔✔Right ventricle
