Insights
Cardiac and gastrointestinal disorders frequently coexist, sharing risk factors and symptoms. This review explores the mechanisms linking these conditions to clarify their relationship and improve clinical diagnosis.
Area of Science:
- Cardiology
- Gastroenterology
- Internal Medicine
Background:
- Cardiovascular diseases (CVDs) are a leading global cause of mortality, with coronary artery disease and arrhythmias being most prevalent.
- Gastrointestinal (GI) disorders, including gastroesophageal reflux and inflammatory bowel diseases, also exhibit high incidence.
- A documented link exists between cardiac and GI conditions due to shared risk factors, symptoms, and potential co-occurrence in patients.
Purpose of the Study:
- To elucidate the underlying mechanisms connecting cardiac and gastrointestinal diseases.
- To investigate the causal or casual nature of the relationship between these two systems.
- To enhance understanding for improved clinical diagnosis and patient management.
Main Methods:
- Literature review synthesizing existing evidence on the cardiac-gastrointestinal link.
- Analysis of shared risk factors and symptom presentation.
- Exploration of pathophysiological mechanisms connecting the two conditions.
Main Results:
- GI disorders can present with chest pain, mimicking cardiac conditions like angina pectoris.
- Cardiac ischemia, such as angina-linked ischemia, can be unmasked or exacerbated by GI issues.
- The interplay between cardiac and GI systems presents diagnostic challenges.
Conclusions:
- The relationship between cardiac and GI diseases is complex, involving shared pathways and bidirectional influences.
- Understanding these mechanisms is crucial for accurate diagnosis and effective treatment strategies.
- Further research is warranted to fully delineate the causal links and optimize patient care.
Abstract:
Cardiovascular diseases are the leading cause of death worldwide: among them, coronary artery disease and arrhythmias represent the most frequent pathological conditions. Similarly, the gastrointestinal disorders, that is, gastroesophageal reflux and inflammatory bowel diseases, have a high incidence in the general population. Several pieces of evidence have documented a link between cardiac and gastrointestinal disorders as they often share similar risk factors and symptoms. Furthermore, both can simultaneously occur in the same patient, thus creating problems in the correct clinical diagnosis. It is well known that gastrointestinal disorders may present with chest pain and mimic angina pectoris. In contrast, they can also unmask heart disease, such as in the case of the angina-linked ischemia. The aim of this review was to elucidate the mechanisms underlying the relationship between cardiac and gastrointestinal diseases to better understand the causal or casual character of such a linkage.
