Abstract
AIM: Some previous studies suggest a long term association between clarithromycin use and cardiovascular events. This study investigates this association for clarithromycin given as part of Helicobacter pylori treatment (HPT). METHODS: Our source population was the Clinical Practice Research Datalink (CPRD), a UK primary care database. We conducted a self-controlled case series (SCCS), a case-time-control study (CTC) and a propensity score adjusted cohort study comparing the rate of cardiovascular events in the 3 years after exposure to HPT containing clarithromycin with exposure to clarithromycin free HPT. Outcomes were first incident myocardial infarction, arrhythmia and stroke. For the cohort analysis we included secondary outcomes all-cause and cardiovascular mortality. RESULTS: 28,552 patients were included in the cohort. The incidence rate ratio of first MI within a year of exposure to HPT containing clarithromycin was 1.07 (95% CI: 0.85-1.34, p = 0.58) and within 90 days was 1.43 (95% CI: 0.99-2.09 p = 0.057) in the SCCS analysis. CTC and cohort results were consistent with these findings. CONCLUSIONS: There was some evidence for a short term association for first MI but none for a long term association for any outcome.
