Historical cohort study to assess the adherence rate of patients randomized clinical trials (RCT) of the pharmaceutical industry in the cardiology appointment and follow-up medical treatment. A study conducted at the cardiology research in a public hospital and university in Porto Alegre, Rio Grande do Sul, Brazil. High adherence was regarded as a ≥ 80%. Revised seven- RCT (120 medical records). It was found that 117 (97%) of patients had adherence to follow-up visits to ≥ 80%, 83.3% of patients had rates of ≥ 80% adherence to medication in the study; the median number of tablets ingested, among patients with good adherence was 175 (72-500) and among patients with lower adherence was 500 (500-962). These results indicate that patients in studies with longer follow up and greater number of oral medications present loss in adhesion.
