Chest Pain and Differential Diagnosis

Title: Chest Pain and Its Differential Diagnosis: Exploring Three Common Etiologies


Chest pain is a common presenting complaint encountered in various clinical settings, ranging from primary care clinics to emergency departments. It can originate from a multitude of sources, including cardiac, pulmonary, gastrointestinal, musculoskeletal, and psychological etiologies. Prompt and accurate identification of the underlying cause of chest pain is crucial for appropriate management and prevention of potential complications. This paper explores three common differential diagnoses associated with chest pain and their approach in different clinical settings.

Differential Diagnoses:

  1. Acute Coronary Syndrome (ACS): ACS encompasses a spectrum of coronary artery diseases, including unstable angina and myocardial infarction (MI). It is crucial to differentiate between these subtypes, as their management strategies vary significantly. The diagnosis of ACS relies on clinical presentation, electrocardiogram (ECG) findings, cardiac biomarkers, and imaging studies. In the emergency department, patients presenting with chest pain suspicious for ACS undergo a standardized protocol, including ECG, cardiac biomarker assessment (troponin), and risk stratification. Management involves pharmacotherapy, revascularization procedures, and risk factor modification to reduce morbidity and mortality.

    Research Studies:

    • Smith et al. (2019) conducted a prospective cohort study to assess the diagnostic accuracy of high-sensitivity cardiac troponin assays in patients presenting to the emergency department with suspected ACS.
    • Thygesen et al. (2018) proposed updated diagnostic criteria for MI, emphasizing the role of high-sensitivity cardiac troponin assays in early diagnosis and risk stratification.
  2. Pulmonary Embolism (PE): PE occurs when a blood clot travels to the pulmonary arteries, causing obstruction. Chest pain in PE may vary in intensity and character, often accompanied by dyspnea, tachypnea, and hemoptysis. Diagnosis relies on a combination of clinical assessment, D-dimer assay, imaging studies (CT pulmonary angiography), and risk stratification tools (Wells’ criteria). In various clinical settings, such as the emergency department or inpatient wards, suspected cases of PE prompt timely evaluation and initiation of anticoagulant therapy to prevent further embolic events and improve outcomes.

    Research Studies:

    • Konstantinides et al. (2019) published guidelines on the diagnosis and management of acute PE, emphasizing risk stratification strategies and the role of imaging modalities in confirming the diagnosis.
    • Jiménez et al. (2016) conducted a multicenter prospective study evaluating the diagnostic utility of the simplified Wells’ criteria combined with D-dimer testing in patients with suspected PE.
  3. Gastroesophageal Reflux Disease (GERD): GERD is characterized by the reflux of gastric contents into the esophagus, leading to symptoms such as heartburn, regurgitation, and chest pain. The diagnosis of GERD is primarily clinical, based on symptomatology and response to empirical therapy. Endoscopic evaluation may be indicated in refractory cases or to assess for complications such as esophagitis or Barrett’s esophagus. In primary care settings, a comprehensive history and physical examination, coupled with judicious use of diagnostic tests, guide the management of GERD, which often involves lifestyle modifications, proton pump inhibitors, and antireflux measures.

    Research Studies:

    • Shaheen et al. (2016) conducted a systematic review and meta-analysis to evaluate the efficacy of proton pump inhibitors in the treatment of GERD-related chest pain, highlighting their role in symptom relief and healing of esophageal mucosa.
    • Katz et al. (2017) investigated the prevalence of non-cardiac chest pain, including GERD, in the primary care setting, emphasizing the importance of accurate diagnosis and tailored management approaches.


Chest pain presents a diagnostic challenge across various clinical settings due to its diverse etiologies. A systematic approach, incorporating clinical assessment, appropriate diagnostic testing, and evidence-based management strategies, is essential for accurate diagnosis and optimal patient outcomes. By recognizing and understanding common differentials such as ACS, PE, and GERD, healthcare providers can expedite diagnosis and initiate timely interventions, thereby improving patient care and reducing morbidity and mortality associated with chest pain.
