Takotsubo cardiomyopathy, also known as "broken heart syndrome," is a cardiac entity characterized by transient left ventricular dysfunction without obstructive atherosclerotic coronary artery disease. An episode of emotional stress is believed to act as a trigger in the development of this syndrome, which typically occurs in female patients. We report a fatal case of a previously healthy 70-year-old woman who suffered an out-of-hospital cardiac arrest and cardiac rupture during emotional distress, due to Takotsubo cardiomyopathy. Ventricular rupture with Takotsubo cardiomyopathy is rare, but our case emphasizes the importance of dealing with this serious and potentially life-threatening disease. Takotsubo cardiomyopathy should be considered as a differential diagnosis in cases of early-developing heart failure, and clinicians should subsequently use adequate diagnostic and therapeutic options.
A 60-year-old man presented to an emergency department 2 h after the ingestion of 8 g of diltiazem (about 40 slow-release capsules, 200 mg/each) in a suicide attempt. The subject was treated with a gastric lavage and activated charcoal; then, a temporary transvenous pacing was also inserted. Despite emergency pharmacological treatment, the subject died about 20 h after ingestion. Postmortem diltiazem and desacetyl-diltiazem concentrations, measured by gas chromatography-mass spectrometry, were as follows: 31.1 mg/mL diltiazem and 9.7 mg/mL desacetyl-diltiazem in blood; 33.1 mg/g diltiazem and 13.7 mg/g desacetyl-diltiazem in brain; 179.5 mg/g diltiazem and 47.5 mg/g desacetyl-diltiazem in lung; 41.8 mg/g diltiazem and 10.1 mg/g desacetyl-diltiazem in heart; 182.1 mg/g diltiazem and 47.3 mg/g desacetyl-diltiazem in liver; 49.2 mg/g diltiazem and 22.6 mg/g desacetyl-diltiazem in kidney; and 294.9 mg/mL diltiazem and 29.4 mg/mL desacetyl-diltiazem in bile. It is interesting to note that although several cases of acute diltiazem poisoning have been reported in literature, only a few were lethal. Diltiazem concentrations found in our case are notably higher than those reported in other studies, including those in which diltiazem ingestion resulted in the death of the patient. Notably, in many of these latter cases, the doses of diltiazem ingested were higher than those taken by our patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
