Brief Summary:

A growing body of evidence links Chlamydia pneumoniae to the progression of coronary heart disease. The purpose of this study is to determine the positive and negative effect of 14 days treatment with clarithromycin 500 mg daily in patients already suffering from stable coronary heart disease. The participants will be followed for at least two years after the treatment.

Abbott Laboratories supplied Clarithromycin and placebo tablets.


Condition or disease Intervention/treatment Phase
Heart Disease Cardiovascular Disease Drug: clarithromycin Phase 3

Detailed Description:

Basic science suggests a fundamental role for inflammation in mediating all stages of coronary heart disease (CHD), and a large number of clinical studies have reported an association between markers of inflammation and CHD. Consequently, infectious agents have been proposed as promoters of atherosclerosis and/or acute coronary syndrome (ACS). Many studies have suggested a relation between Chlamydia pneumoniae (C. pneumoniae) infection and CHD, and C. pneumoniae has been demonstrated in atherosclerotic tissue.

Macrolide antibiotics are effective in eradication of C. pneumoniae from atherosclerotic plaques. Two small trials showed significant beneficial effects of macrolides on cardiovascular morbidity in patients with ACS. To corroborate and extend these findings, we undertook a randomised, placebo-controlled trial with clarithromycin in patients with stable CHD in order to test the hypothesis that intervention with a macrolide would reduce cardiovascular risk with regard to mortality and morbidity.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Clarithromycin
Clarithromycin is a lipophilic semi-synthetic macrolide antibiotic. The lipophilic nature of the drug allows it to easily penetrate into body fluids and tissues and accumulate intracellularly. Side effects are few, apart from trivial gastrointestinal complaints, and severe side effects are rarely observed during standard treatment.
 Drug: clarithromycin
Placebo Comparator: Placebo
Placebo comparator
 Drug: clarithromycin
