This paper provides a comprehensive overview of non-cardiac chest pain (NCCP), a recurring condition defined as angina-like retrosternal chest pain without a cardiac origin. It surveys the major digestive, musculoskeletal, respiratory, and psychological causes of NCCP and contrasts them with true cardiac symptoms. Drawing on qualitative research into patient pain experiences and a meta-analysis of NCCP prevalence studies, the paper examines how unexplained chest pain affects daily life, generates anxiety, and drives repeated emergency room visits. It concludes by addressing the substantial economic burden of NCCP — estimated at up to $1.8 billion annually — and calls for improved diagnostic and cognitive-based treatment strategies.
The paper demonstrates effective synthesis of primary research: it does not merely summarize individual studies but draws thematic connections between them — linking the qualitative finding that anxiety amplifies pain to the meta-analytic finding that psychological comorbidity is common in NCCP patients. This cross-study synthesis strengthens the paper's central argument that NCCP is both underdiagnosed and undertreated.
The paper opens with a background section defining cardiac versus non-cardiac chest pain and cataloguing NCCP causes by category (digestive, musculoskeletal, respiratory, and other). It then transitions to an article analysis section covering a qualitative emergency-department study on patient pain experiences, followed by a meta-analysis of NCCP prevalence and its association with GERD. A brief conclusions section addresses healthcare costs and the need for resource reallocation. References follow in MLA-style works-cited format.
Chest pain is one of the most common reasons people call for emergency services or visit the emergency room. Public education about heart attacks has reinforced the urgency of seeking immediate medical treatment when cardiac trouble is suspected. However, chest pain does not always signal a heart attack and may be entirely unrelated to the cardiovascular system. Often no clear reason for such pain presents itself during examination, but understanding the perception and pain experience can help medical professionals interpret the different experiences that lead patients to panic about chest pain (Jerlock, Gaston-Johansson, & Danielson, 2005).
Chest pain that is typically related to a cardiac issue is usually associated with one or more of the following symptoms: (1) pressure, fullness, or extreme tightness in the chest; (2) crushing or searing pain that radiates to the back, upward through the jaw, and especially through the left arm; (3) pain that lasts more than a few moments or goes away and returns repeatedly; or (4) pain combined with shortness of breath, sweating, dizziness, or nausea.
Chest pain that is typically unrelated to cardiovascular issues is usually described as: (1) a burning sensation behind the sternum; (2) a sour taste or a sensation of food or liquid re-entering the mouth; (3) difficulty swallowing; (4) pain that changes in intensity when body position is changed; (5) pain that intensifies with deeper breaths or coughing; and (6) pain or discomfort when pressure is applied to the chest (Mayo Clinic Staff, 2011).
Cardiac causes usually signal a heart attack, angina, pericarditis, a coronary spasm, or an aortic dissection. All are serious conditions, and care should be taken to either travel by ambulance or have someone drive the patient to the nearest emergency room. However, there are a number of other causes of chest pain that involve the digestive system, musculoskeletal structures, respiratory system, or other non-cardiac-related issues. These are collectively called non-cardiac chest pain (NCCP) and are defined as recurring, angina-like, retrosternal chest pain of a non-cardiac origin.
Digestive causes typically involve the stomach, esophagus, or intestines.
Musculoskeletal causes are typically centered around the rib cage or the abdominal muscles.
Respiratory causes are centered around the lungs.
Other causes range from psychological issues to viral infections and serious diseases.
The interrelationship between chest pain and patient perception is a critical component in understanding how unexplained chest pain affects the daily lives of individuals. It is quite common for patients with unexplained chest pain to have symptoms suggestive of ischemia but, upon testing, to show no evidence of coronary heart disease. In fact, many patients with chest pain symptoms have already had negative cardiac evaluations and, despite reassurances that they are not experiencing heart problems, still perceive any chest pain as a "heart issue" requiring an emergency room visit. This perception contributes to severe anxiety, confusion, and further expensive and repetitive testing (Jerlock et al., 2005).
As part of a larger study using quantitative methods to examine psychosocial influences on patients' chest pain experiences, a qualitative approach was applied with 19 mixed-gender patients admitted to a university emergency department over a 90-day period. The study criteria included patients under age 70 with chest pain symptoms but no clinical organic causes, who had experienced at least two chest pain incidents over more than four weeks. These patients ranged in age from 18 to 63 (median age = 51 for women, 37 for men). An open-ended, unstructured interview was conducted in a narrative format, structured as a conversation in which patients were encouraged to describe their experience. The dialogue focused on what it is like to have chest pain, how the pain is characterized, and how it influences activities of everyday life. Interviews lasted from 40 to 75 minutes, with one exception lasting 140 minutes (Jerlock, 958).
In order to interpret the meaning of these dialogues — particularly given the relatively small sample size — a content analysis was performed using the following method:
This analysis produced some interesting commonalities regarding the pain experience. These commonalities demonstrate that while the chest pain experience may be individualized, the overall pattern is broadly shared:
The shared experience documented in the study confirms that unexplained chest pain intrudes negatively into the everyday lives of those who experience it. It is likely that the co-morbidity of anxiety and fear elevated blood pressure and caused additional symptoms. When pain increased or became so intense that patients could no longer manage it, they turned to emergency services. Other research confirms that the stress caused by chest pain also produces a circular pattern: more pain leads to more stress and worry, which in turn intensifies pain and drives further trips to the emergency room (Unexplained Chest Pain Can be Due To Stress, 2009).
