0199: Acute coronary syndrome with ST elevation in patients younger than 35 years-aetiologies, baseline characteristics and in-hospital clinical outcome

PurposeCoronary atherosclerosis begins early in life, but acute coronary syndromes in adults aged <35 years are rare. We aimed to investigate the rate of occurrence, clinical and angiographic characteristics, and in-hospital clinical outcome of STEMI in young patients who were referred to our cardiology departement.MethodsFrom 2003 to 2013, data of all patients with STEMI aged <35 years were retrospectively retrieved from our database. Baseline, procedural characteristics, and clinical outcome were analyzed. In 2013 we prospectly analyzed the causal lesion with a systematic coronary angiogram and a comparison between patients in whom an underlying atypical aetiology was found (non-ATS group; ATS: atherosclerosis) and patients in whom no such aetiology was detected (ATS group).ResultsA total of 98 young patients with STEMI aged
