Congestive heart failure[source]

The eds.congestive_heart_failure pipeline component extracts mentions of congestive heart failure. It will notably match:

Mentions of various diseases (see below)
Heart transplantation
AF (Atrial Fibrillation)
Pacemaker

Usage

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,
            bars=True,
            biology=True,
            doctors=True,
            web=True,
            coding=True,
            footer=True,
        ),
    ),
)
nlp.add_pipe(eds.congestive_heart_failure())

Below are a few examples:

12345

text = "Présence d'un oedème pulmonaire"
doc = nlp(text)
spans = doc.spans["congestive_heart_failure"]

spans
# Out: [oedème pulmonaire]

text = "Le patient est équipé d'un pace-maker"
doc = nlp(text)
spans = doc.spans["congestive_heart_failure"]

spans
# Out: [pace-maker]

text = "Un cardiopathie non décompensée"
doc = nlp(text)
spans = doc.spans["congestive_heart_failure"]

spans
# Out: []

text = "Insuffisance cardiaque"
doc = nlp(text)
spans = doc.spans["congestive_heart_failure"]

spans
# Out: [Insuffisance cardiaque]

text = "Insuffisance cardiaque minime"
doc = nlp(text)
spans = doc.spans["congestive_heart_failure"]

spans
# Out: []
