rome_iv_functional_chest_pain: Rome IV Diagnostic Criteria for Functional Chest Pain

Description

Evaluates the Rome IV criteria for diagnosing Functional Chest Pain of presumed esophageal origin. Diagnosis requires recurrent retrosternal chest pain (not heartburn) that is not explained by organic esophageal disease (e.g., structural, motility, or reflux disease). Symptoms must be chronic (onset >= 6 months, active >= 3 months).

Usage

rome_iv_functional_chest_pain(retrosternal_pain, other_esophageal_symptoms,
                              normal_egd, normal_esophageal_motility,
                              esophageal_reflux_excluded, symptom_onset_ge_6_months,
                              symptoms_active_last_3_months)

Value

A list containing:

Diagnosis

"Criteria Met for Functional Chest Pain" or "Criteria Not Met".

Arguments

retrosternal_pain

Numeric (0 or 1). Presence of retrosternal pain or discomfort. (1 = Yes).

other_esophageal_symptoms

Numeric (0 or 1). Presence of associated esophageal symptoms (e.g., heartburn, dysphagia). (1 = Yes). Note: The diagnosis requires the *absence* of these secondary symptoms.

normal_egd

Numeric (0 or 1). Normal Esophagogastroduodenoscopy (EGD) (ruling out structural/mucosal lesions like esophagitis, ulcers). (1 = Yes).

normal_esophageal_motility

Numeric (0 or 1). Normal esophageal motility (ruling out major motor disorders like achalasia, spasm). (1 = Yes).

esophageal_reflux_excluded

Numeric (0 or 1). Absence of evidence that gastroesophageal reflux (GERD) is the cause of the symptom (e.g., negative pH monitoring or symptom relief with PPIs). (1 = Yes).

symptom_onset_ge_6_months

Numeric (0 or 1). Did symptom onset occur at least 6 months prior to diagnosis? (1 = Yes).

symptoms_active_last_3_months
