Helicobacter pylori infection and mortality from ischaemic heart disease : negative result from a large, prospective study.
To determine whether there is an independent association between Helicobacter pylori infection of the stomach and ischaemic heart disease.
Design-Prospective study with measurement of IgG antibody titres specific to H pylori on stored serum samples from 648 men who died from ischaemic heart disease and 1296 age matched controls who did not (nested case-control design).
Subjects-21 520 professional men aged 35-64 who attended the British United Provident Association (BUPA) medical centre in London between 1975 and 1982 for routine medical examination.
Main outcome measure-Death from ischaemic heart disease.
The odds of death from ischaemic heart disease in men with H pylori infection relative to that in men without infection was 1.06 (95% confidence interval 0.86 to 1.31).
In a separate group of 206 people attending the centre, plasma fibrinogen was virtually the same in those who were positive for H pylori (2.62 g/l) and those who were negative (2.64 g/l).
Conclusions-A study that by its size and design minimised both random error and socioeconomic bias found no relation between H pylori infection and ischaemic heart disease.
The validity of the study was shown by its confirmation of the recognised association between H pylori infection and stomach cancer (odds ratio 4.0 (1.9 to 8.2) ; P<0.001). (...)
