Abstract Background Complementary and alternative medical (CAM) therapies are becoming increasingly popular, yet little information is available about the prevalence and patterns of CAM therapy use by patients with cardiovascular disease (CVD). Methods Interviewers administered telephone questionnaires to 107 patients randomly selected from a stratified cohort of 2487 eligible patients participating in a registry of patients with CVD. Results The current use of CAM therapies was reported by 64% of the patients surveyed. Nutritional supplements (40%) and megadose vitamins (35%) were the most frequently used preparations. Most CAM therapy users (65%) cited their underlying cardiac condition as the reason for taking such therapy. The most common sources of information about CAM were a friend or relative (43%) or the respondent’s usual physician. However, although 80% of respondents claimed that they had discussed their use of CAM therapies with their physician, 58% of respondents taking a potentially toxic cardiovascular medication (digoxin, warfarin, sotalol, or amiodarone) were simultaneously taking an oral supplement. Conclusion The use of CAM therapies was high in the cohort of patients surveyed. Physicians caring for patients with CVD need to inquire about CAM therapy use. Further scientific study should be performed to evaluate the potential benefits and risks of CAM therapies in this patient population.
