The prognostic value of autoantibodies against β1-adrenoceptor and cardiac troponin-I for clinical outcomes in STEMI

AimsThe prevalence and potential role of autoantibodies against the β1-adrenoceptor autoantibody (β1-aab) and cardiac troponin-I (anti-cTnI) in patients with ST-elevation myocardial infarction (STEMI) are unknown. The aim of this study is to test whether β1-aab and anti-cTnI are prevalent in STEMI p
