5 papers analyzed
These studies suggest that left arm pain can be a symptom of heart attack, specifically related to conditions like angina pectoris and ischaemic heart disease, but it can also be caused by other conditions such as seizures or extracephlic cluster headaches.

Left Arm Pain and Heart Attack: Understanding the Connection
Introduction to Myocardial Infarction Symptoms
Myocardial infarction (MI), commonly known as a heart attack, is a critical medical condition caused by the blockage of blood flow to the heart muscle, leading to tissue damage due to lack of oxygen. One of the hallmark symptoms of a heart attack is pain or discomfort that radiates to the left arm, among other areas. This symptom is often accompanied by chest pain, shortness of breath, sweating, and other distressing signs.
Left Arm Pain as a Symptom of Heart Attack
Common Presentation and Diagnostic Challenges
Left arm pain is a well-documented symptom of heart attacks and other cardiac events. It is often described as a constricting, squeezing, or cramp-like sensation that can extend from the chest to the arm, sometimes reaching the fingers . This pain can be misleading, as it may be mistaken for musculoskeletal issues or other non-cardiac conditions, especially when it occurs without concurrent chest pain.
Historical and Clinical Observations
Historical medical literature, such as Heberden's description of angina pectoris and Herrick's early work on coronary occlusion, highlights the significance of arm pain in diagnosing heart conditions. Patients often describe the pain as a tightness or pressure rather than sharp pain, and it can radiate to other areas such as the jaw, neck, or back. This referred pain can sometimes be more troubling than the chest pain itself, leading to misdiagnosis or delayed treatment.
Case Studies and Clinical Reports
Differential Diagnosis in Emergency Settings
A case study involving a 67-year-old male presenting with left arm numbness and syncopal episodes underscores the complexity of diagnosing heart-related issues. Despite his history of cardiac problems, an EEG revealed seizures as the underlying cause, highlighting the importance of thorough diagnostic procedures in emergency settings.
Cluster Headaches Mimicking Cardiac Symptoms
Another case involved a 67-year-old woman who experienced left-sided chest tightness and arm pain with paresthesia, which were initially suggestive of a cardiac event. However, her symptoms were part of a pattern of cluster headaches, which can mimic heart attack symptoms and complicate diagnosis. This case emphasizes the need for careful evaluation to distinguish between cardiac and non-cardiac causes of left arm pain.
Conclusion
Left arm pain is a significant symptom of myocardial infarction and other cardiac conditions, often presenting alongside chest pain and other distressing symptoms. However, it can also be a symptom of other medical issues, making accurate diagnosis crucial. Understanding the nuances of how left arm pain manifests in heart attacks and differentiating it from other conditions is essential for timely and effective treatment.
