- Investigations
1. A septic patient with three-vessel disease has chest pain, ST changes and raised troponin, and an 80-year-old diabetic has nausea, vomiting and bradycardia without chest pain. Which statements are correct?
- AThe first is a type 1 MI, and the second is gastroenteritis
- BThe first is type 3, and the second is pericarditis
- CThe first is myocardial injury, and the second is anxiety
- DThe first is a type 2 MI from supply-demand mismatch, and the second may be a painless inferior MI
Show answer
D. The first is a type 2 MI from supply-demand mismatch, and the second may be a painless inferior MI Type 2 MI needs clinical evidence of ischaemia with CAD and major non-cardiac stress; painless MI is common in older and diabetic patients and vomiting and bradycardia are common in inferior MI.
2. A patient has a low-pitched mid-diastolic rumble at the apex and axilla best heard with the bell, and another has a soft decrescendo early diastolic murmur at the left sternal edge heard with the diaphragm sitting forward in expiration. Which lesions fit?
- AMitral stenosis, and aortic or pulmonary regurgitation
- BAortic stenosis, and mitral regurgitation
- CTricuspid regurgitation, and pulmonary stenosis
- DMitral regurgitation, and aortic stenosis
Show answer
A. Mitral stenosis, and aortic or pulmonary regurgitation Mid-diastolic murmurs come from mitral or tricuspid stenosis or increased flow; early diastolic murmurs come from aortic or pulmonary regurgitation.
3. A patient has rest pain for 3 weeks with ankle pressure of 45 mmHg, and another has a cold pale paralysed leg for 2 hours from an embolus. Which statements are correct?
- AThe first is acute, and the second needs amputation
- BThe first is critical limb ischaemia with multilevel disease, and the second needs urgent vascular surgical discussion and heparin because embolism causes necrosis within 6 hours
- CThe first is claudication, and the second can be observed
- DThe first is subcritical, and the second needs statins
Show answer
B. The first is critical limb ischaemia with multilevel disease, and the second needs urgent vascular surgical discussion and heparin because embolism causes necrosis within 6 hours Rest pain with ankle pressure below 50 mmHg is CLI; embolic acute limb ischaemia needs revascularisation within about 6 hours and heparin unless contraindicated.
