Myocardial infarction

The eds.myocardial_infarction pipeline component extracts mentions of myocardial infarction. It will notably match:

Mentions of various diseases (see below)
Mentions of stents with a heart localization

Extensions

On each span span that match, the following attributes are available:

span._.detailed_status: set to "PRESENT"
span._.assigned: dictionary with the following keys, if relevant:
- heart_localized: localization of the stent or bypass

Examples

import edsnlp, edsnlp.pipes as eds

nlp = edsnlp.blank("eds")
nlp.add_pipe(eds.sentences())
nlp.add_pipe(
    eds.normalizer(
        accents=True,
        lowercase=True,
        quotes=True,
        spaces=True,
        pollution=dict(
            information=True,

            doctors=True,
            web=True,
            coding=True,
            footer=True,
        ),
    ),
)
nlp.add_pipe(eds.myocardial_infarction())

Below are a few examples:

text = "Une cardiopathie ischémique"
doc = nlp(text)
spans = doc.spans["myocardial_infarction"]

spans
# Out: [cardiopathie ischémique]

text = "Une cardiopathie non-ischémique"
doc = nlp(text)
spans = doc.spans["myocardial_infarction"]

spans
# Out: []

text = "Présence d'un stent sur la marginale"
doc = nlp(text)
spans = doc.spans["myocardial_infarction"]

spans
# Out: [stent sur la marginale]

span = spans[0]

span._.assigned
# Out: {'heart_localized': [marginale]}

text = "Présence d'un stent périphérique"
doc = nlp(text)
spans = doc.spans["myocardial_infarction"]

spans
# Out: []

text = "infarctus du myocarde"
doc = nlp(text)
spans = doc.spans["myocardial_infarction"]

spans
# Out: [infarctus du myocarde]

Authors and citation

The eds.myocardial_infarction component was developed by AP-HP's Data Science team with a team of medical experts. A paper describing in details the development of those components is being drafted and will soon be available.
