You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Disease", "Chemical"].

Please return the output as a JSON object of the format: {"Chemical" : ["Naloxone", ...], "Disease" : ["Hypotensive", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Case report: Dexatrim (Phenylpropanolamine) as a cause of myocardial infarction. Phenylpropanolamine (PPA) is a sympathetic amine used in over-the-counter cold remedies and weight-control preparations worldwide. Its use has been associated with hypertensive episodes and hemorrhagic strokes in younger women. Several reports have linked the abuse of PPA with myocardial injury, especially when overdose is involved. We report here the first case of Dexatrim (PPA)-induced myocardial injury in a young woman who was using it at recommended doses for weight control. In addition, we review the 7 other cases of PPA related myocardial injury that have been reported so far. Physicians and patients should be alert to the potential cardiac risk associated with the use of PPA, even at doses generally considered to be safe.
