المصادر مختلفة. ملفات الدفعة فيها إجابتين، وما نرجّح وحدة على الثانية. سبب كل وحدة في الشرح تحت:
- إجابة: A. Rule out obstructive coronary artery disease
- إجابة ثانية: C. Rule out amyloidosis
With EF 30% (systolic HF), the sources name ischaemic heart disease as the most common cause, and advise coronary angiography to exclude CAD as the underlying cause of CHF, so ruling out obstructive CAD is the best supported next step. Why disputed: the stem's mention of inflammatory bowel disease may be a deliberate hint, since the sources link IBD to AA amyloidosis. Against that, the sources list amyloidosis under restrictive/diastolic dysfunction with preserved EF, which does not fit EF 30%. The recalled stem is garbled, and the bank itself recorded this question as uncertain.
ليش كل خيار صح أو غلط
-
A
ليش صح
Supported by the Step-Up HF chapter: cardiac catheterisation can clarify the cause of CHF, and coronary angiography is considered to exclude CAD as an underlying cause.

C
ليش صح
Supported by the HF notes: infiltrative disease such as amyloidosis is a listed cause of systolic HF. The same notes also list amyloid under restrictive (diastolic) causes.

D
ليش غلط
Myocarditis is a listed cause of systolic HF, but the HF notes name ischemic heart disease as the most common cause.
