Summary
Pulmonary embolism (PE) can mimic heart disease, presenting with severe chest pain and ECG changes. Early diagnosis is crucial for this life-threatening condition, even when symptoms are nonspecific.
Area of Science:
- Cardiology
- Pulmonology
- Emergency Medicine
Background:
- Pulmonary embolism (PE) is a critical condition requiring prompt diagnosis and management.
- Recognizing PE is vital, especially when initial symptoms overlap with other serious diseases like ischaemic heart disease.
Observation:
- Three patients (two men, 60 and 61; one woman, 76) presented with severe chest pain and electrocardiographic (ECG) changes suggestive of ischaemic heart disease.
- These patients exhibited dyspnoea and haemodynamic instability, with a lack of response to initial treatments.
- Clinical suspicion for PE arose due to the severity and persistence of symptoms, leading to diagnosis.
Findings:
- Electrocardiographic changes in PE often indicate right-sided heart overload and potential arterial hypoxaemia.
- While ECG abnormalities are common in PE, they are frequently nonspecific, primarily involving ST-T segment changes.
- The presented cases highlight how atypical presentations of PE can initially be misdiagnosed.
Implications:
- This case series underscores the importance of considering pulmonary embolism in patients with unexplained chest pain and ECG abnormalities, even when cardiac causes are suspected.
- Clinicians should maintain a high index of suspicion for PE in patients with haemodynamic instability and respiratory distress, alongside cardiac-like symptoms.
- Further research into specific ECG markers for early PE detection in complex cases may improve patient outcomes.
