Hydrochlorothiazide-induced pulmonary edema with severe acute myocardial dysfunction

A 73-year-old woman presented with acute pulmonary edema and hypotension less than 1 h after taking hydrochlorothiazide 50 mg, a reaction which has been reported as a rare but classic adverse drug response. Though prior cases have supported a noncardiogenic pulmonary edema syndrome, hemodynamic monitoring in this patient demonstrated a refractory low cardiac output state for more than 24 h. In the absence of other etiologies, this represents a new finding.
