DOZORETZ, Daniel et al. Severe poisoning by Nicotiana glauca (Palán Palán) with stunned myocardium. Acta toxicol. argent. [online]. 2021, vol.29, n.3, pp.121-126. ISSN 1851-3743.

Nicotiana glauca is a shrub with bluish green leaves and a pendulous tubular yellow flower. It has pyridine alkaloids, such as nicotine, nornicotine, anatabine and anabastine (structural analog of Nicotine). We present the case of a 50 years old pa- tient with acute generalized muscle weakness that evolves to respiratory arrest, after accidentally ingesting an unknown quantity of Nicotiana glauca leaves, grown in a home vegetable garden, using a hydroponic technique and confused by her cohabiting with spinach. She presented increased lactate and Ultra Sensitive Troponin and Left Ventricular Global Hypokinesia in the echo- cardiogram, compatible with Myocardial Stunned, that it evolved favorably. There are few reports, animal and human deaths have been reported following accidental ingestion of Nicotiana glauca. The onset of the symptoms is early, with a biphasic pattern, with vomiting and sympathetic stimulation, followed by ganglionic and neuromuscular blockage and may present respiratory arrest, shock, seizures and coma. Myocardial Stunned is a prolonged myocardial dysfunction with gradual return of contractile activity after a brief episode of severe ischemia, it can be asymptomatic, and it can present alterations in the electrocardiogram, cardiac enzymes or echocardiogram. Generally presents a benign prognosis, being able to present heart failure with concurrent patholo- gies or increased requirements.
