Brief Summary

Patients with unexplained atherosclerosis (severe atherosclerosis not explained by traditional risk factors) will receive fecal microbial transplants (FMT) from patients with a Protected phenotype (patients who have high levels of risk factors but little or no carotid atherosclerosis). The objective is to determine what changes in the intestinal microbiome are associated with a decline in plasma levels of toxic metabolites of the itnestinal microbiome such as trimethylamine N-oxide (TMAO) and p-cresylsulfate. The intention is to develop an ecosystem therapeutic of cultured bacteria to treat atherosclerosis.

Eligibility Criteria

Inclusion Criteria: * Severe atherosclerosis, with total plaque area in the top quartile (\>119 mm2), not explained by traditional risk factors in linear regression (residual score \>= 2) Exclusion Criteria: * Excluded will be patients unwilling/unable to provide informed consent, unwilling to ingest the stool capsules at baseline, patients with moderate to severe renal failure (eGFR\<50), immunosuppressed patients, and patients with cancer, unstable angina, planned carotid revascularization or other conditions that might be expected to reduce their survival to \< 1 year (including age \>80).
