Insights
Ischemic heart disease (IHD) is a leading cause of death. This review explores the potential link between IHD and Helicobacter pylori (H. pylori) infection, analyzing experimental data for biological plausibility beyond traditional risk factors.
Area of Science:
- Cardiology
- Infectious Diseases
- Epidemiology
Background:
- Ischemic heart disease (IHD) remains a primary cause of mortality and disability globally.
- Traditional cardiovascular risk factors do not account for all IHD cases, necessitating research into novel etiologic factors.
- Chronic infections, such as Helicobacter pylori (H. pylori), are being investigated for their potential role in IHD pathogenesis.
Purpose of the Study:
- To critically analyze existing experimental data regarding the association between H. pylori infection and IHD.
- To evaluate the biological plausibility of H. pylori as a contributing factor to IHD.
- To guide future clinical research by assessing the consistency of experimental findings.
Main Methods:
- Systematic review and critical analysis of experimental studies.
- Evaluation of laboratory and mechanistic data linking H. pylori to cardiovascular pathways.
- Assessment of geographical and design variations in epidemiological studies.
Main Results:
- Conflicting results from epidemiological studies highlight the need for biological plausibility assessment.
- Experimental data provides insights into potential mechanisms connecting H. pylori to cardiovascular disease.
- Consistency in biological plausibility may offer a clearer understanding than epidemiological data alone.
Conclusions:
- Experimental evidence is crucial for understanding the potential role of H. pylori in IHD.
- Further investigation into the biological mechanisms is warranted.
- Findings may inform the design of future clinical trials investigating H. pylori and IHD.
Abstract:
Despite the remarkable advances made in primary prevention and treatment, ischemic heart disease (IHD) remains the leading cause of death and a significant cause of disability in developed countries. Since traditional cardiovascular risk factors failed to predict all cases of IHD, there is an intensive research to explore other potential etiologic factors. Among these, numerous studies have considered the theoretical link between IHD and chronic infections, including Helicobacter pylori (H. pylori). Considering that epidemiologic studies have produced conflicting results, due to geographical variations of IHD and H. pylori prevalence as well as heterogeneity of study designs, an alternative way to analyze this topic is to assess if consistency for a biological plausibility exists. In this review we critically analyzed the experimental data on this topic, to assess whether their results could lead future clinical studies.

In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...

In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
