Regadenoson for Patients with Coronary Artery Disease and Family History of Myocardial Infarction
Indications and Risk Assessment
- Family history of premature cardiovascular disease, defined as cardiovascular disease occurring in a first-degree male relative <55 years of age or a first-degree female relative <65 years of age, increases baseline cardiovascular disease risk by 1.5-2.0 fold 1
- The strength of risk increases with younger age of onset, increasing number of affected relatives, and closer genealogical proximity 1
- Almost 75% of individuals with premature coronary heart disease have a positive family history, highlighting opportunities for prevention 1
- Family history of myocardial infarction is an important risk factor that should be considered in the overall cardiovascular risk assessment 3
Patient Management
- For patients with coronary artery disease and stents, functional imaging tests like regadenoson stress MPI are preferred over anatomical assessment 2
- The American College of Cardiology recommends ensuring optimal medical therapy and risk factor modification as part of the comprehensive management approach for patients with established coronary artery disease 4
- The patient's family history of myocardial infarction should inform aggressive secondary prevention strategies but does not contraindicate the use of regadenoson for stress testing 1, 2
