High-Yield Cross-System Disease Bridges
Multi-system pathophysiology heavily tested on COMLEX Level 1 & USMLE Step 1.
Acute or chronic heart failure causes renal venous hypertension and arterial underfilling → RAAS hyperactivation → worsening fluid retention and progressive renal failure.
Cirrhosis with severe portal HTN triggers massive splanchnic nitric oxide release → extreme systemic vasodilation → compensatory renal vasoconstriction and oliguric AKI without intrinsic renal lesions.
Primary pulmonary parenchymal or vascular pathology (COPD, IPF, recurrent PE) induces hypoxic vasoconstriction → chronic pulmonary HTN → right ventricular hypertrophy and right heart failure.
Resistant HTN workup: Primary hyperaldosteronism (Conn syndrome: high aldo, low renin, hypokalemia), Pheochromocytoma (episodic paroxysms, metanephrines), and Cushing syndrome.
