Background Although consensus guidelines for pretreatment evaluation and monitoring of propranolol therapy in patients with infantile hemangiomas (IH) have been formulated, little is known about the cardiovascular side effects. Objectives We sought to analyze cardiovascular evaluations in patients with IH at baseline and during treatment with an oral beta-blocker. Methods Data from 109 patients with IH were retrospectively analyzed. Patient and family history, pretreatment electrocardiogram (ECG), heart rate, and blood pressure were evaluated before initiation of beta-blocker therapy. Blood pressure and standardized questionnaires addressing side effects were evaluated during treatment. Results Questionnaire analyses (n = 83) identified 3 cases with a family history of cardiovascular disease in first-degree relatives. ECG findings were normal in each case and no serious complication of therapy occurred. ECG abnormalities were found in 6.5% of patients but there were no contraindications to beta-blocker therapy and no major complications. Hypotension in 9 patients did not require therapy adjustment. In all, 88 parents (81%) reported side effects during beta-blocker treatment. Limitations The relatively small patient cohort is a limitation. Conclusion Pretreatment ECG is of limited value for patients with an unremarkable cardiovascular history and a normal heart rate and blood pressure. Hypotension may occur during treatment.
