Helicobacter pylori is an aetiological factor for ischaemic heart disease: the case against.
Helicobacter pylori is one of four organisms often investigated for ari association with ischaemic heart disease. The four, including Chlamydia pneumoniae, Cytomegalovirus and Herpes virus, cause low-grade, life-long infections that can produce a persistent inflammation, the kind that leads to heart disease. Several studies suggest an association, but others suggest none. Patients with poor access to medical care are more likely to become infected and also more likely to suffer from coronary artery disease. Although the literature data are provocative and interesting, the two things may not be related. Helicobacter pylori infection is quite prevalent among individuals without ischaemic heart disease and absent in many of those with ischaemic heart disease. Thus, more definite answers about whether there is any link between Helicobacter pylori and cardiovascular disease are needed. It would be essential to establish the specific mechanisms that possibly confer vulnerability or protection toward coronaropathy. But a definite answer could come from clinical trials designed to test whether antibiotics can prevent the disease. Until now, no randomised trial has suggested a positive effect of Helicobacter pylori eradication in reducing the incidence of cardiac events.
