Secondary Causes of Hypertensive Crises

Secondary causes of hypertensive crisis are protean and include left-ventricular failure; acute coronary syndromes; acute aortic dissection; thyroid disorders; and chemical toxicities (cocaine, diet drugs, and steroids, all which up-regulate cardiac β receptors). Pheochromocytomas account for a small portion of HTN crises (< 0.3%).[26,27] Despite the low incidence of pheochromocytoma (1 per 500,000), the condition should always be considered in the differential diagnosis of HTN crisis. Additional causes of HTN crisis to consider are renal artery stenosis (< 1% of cases), acute glomerulonephritis, collagen vascular conditions, eclampsia and pre-eclampsia, severe HTN following kidney transplant, and transient postoperative HTN.
