Descriptive Information
Brief TitleIdentification of Underlying Conditions in Men Prescribed a PDE5 Inhibitor
Official TitlePrevalence and Incidence of Underlying Disease Diagnosed in Men With Erectile Dysfunction When Prescribed a PDE5i for the First Time
Brief SummaryErectile dysfunction (ED) has been identified as an independent risk factor for existing cardiovascular disease, preceding a major cardiovascular event by an average of about 5 years. Are men prescribed a PDE5 inhibitor for ED more likely to have a new diagnosis of underlying medical conditions compared to men of a similar age not receiving PDE5 inhibitor treatment?
