Q903. A 57-year-old man presents with predictable retrosternal chest pressure during brisk walking, relieved by rest. He has hypertension and dyslipidaemia. Cardiovascular examination reveals normal heart sounds, no murmurs, normal peripheral pulses, and no signs of heart failure. His resting ECG is also normal.

Q906. A 67-year-old woman previously experienced predictable exertional chest discomfort that resolved with rest. Over the previous 48 hours, the episodes have become more frequent and prolonged, including chest pressure while sitting. There is no fever or pleuritic pain.

Q913. A 72-year-old man with diabetes mellitus and chronic kidney disease undergoes coronary angiography using iodinated contrast medium. During subsequent monitoring, his serum creatinine rises significantly. Other major causes of acute kidney injury are excluded.

Q914. A 62-year-old man presents to the emergency department with severe central chest pressure radiating to his left arm. The pain began 30 minutes ago and is associated with diaphoresis and nausea. His blood pressure is 128/78 mmHg, pulse is 96/min, and oxygen saturation is 97% on room air.

Q923. A 70-year-old man has disabling exertional angina despite optimised medical treatment. Coronary angiography demonstrates 80% stenosis of the left main coronary artery, 60% stenosis of the proximal left anterior descending artery and 70% stenosis of a major obtuse marginal branch. His left ventricular ejection fraction is 45%. He is considered suitable for cardiac surgery, and the coronary anatomy is amenable to complete surgical revascularisation.

Q1109. A 22-year-old man presents with severe chest pain and tachycardia following cocaine exposure. ECG shows sinus tachycardia without persistent ST elevation. His initial troponin is normal, but the symptoms began only 30 minutes ago. Which statement is most appropriate?

A. A negative initial troponin definitively excludes acute myocardial infarction.

B. Routine fibrinolysis is indicated solely because cocaine was used.

C. Immediate discharge is appropriate whenever the first ECG is nondiagnostic.

D. A normal initial ECG proves there is no myocardial ischaemia.

E. Acute coronary syndrome remains possible and requires appropriate monitored evaluation and serial testing.

“Beta-thalassemia watching you prescribe iron because all you saw was microcytic anemia and you ignored the normal ferritin.”

A 68-year-old woman with type 2 diabetes mellitus and hypertension presents with intermittent central chest heaviness at rest over the preceding four hours, with the longest episode lasting 30 minutes. She is now pain-free. Her pulse is 84 beats/min, blood pressure is 146/86 mmHg, and oxygen saturation is 96% on room air. There are no clinical signs of heart failure. ECG demonstrates 2 mm horizontal ST-segment depression in leads V4–V6 and T-wave inversion in leads I and aVL. High-sensitivity troponin T is 86 ng/L on arrival and rises to 310 ng/L three hours later (upper reference limit 14 ng/L). Her creatinine is 82 µmol/L, and she has received aspirin 300 mg.
