Cardiovascular disease is the leading cause of death. In addition to the well-known risk factors associated with cardiovascular disease, such as age, diabetes mellitus, smoking, hypertension, and obesity, there has been a growing concern regarding cardiac complications stemming from the Gram-negative bacteria Helicobacter pylori. While H. pylori is most commonly associated with chronic gastritis, peptic ulcer disease, gastric adenocarcinoma, and gastric lymphoma, it has also been implicated in extra gastric manifestations, encompassing cardiac, neurologic, ocular, and dermatologic issues. Key virulent factors for coronary artery disease include the vacuolating cytotoxin gene A and the cytotoxin-associated gene A. The most likely pathogenic mechanism of the relationship between H. pylori and coronary artery disease is initiating a chronic inflammatory process associated with infection and the modifications of classic risk factors. These alterations lead to the creation of prothrombotic and procoagulant environments. Here, we review the cardiac manifestations of H. pylori and the underlying pathophysiological mechanisms.
