    Background:
    Recently it was shown that 15% of stage III NSCLC patients, treated with thoracic radiotherapy in dose-escalated trials, suffer from late cardiac events.[1] However, the prevalence of pre-existent cardiac co-morbidity in daily clinical practice in these patients and the development of cardiac events during follow-up is still unclear. As these patients are treated with curative intent and have a five survival rate 25%, there is need for a study to investigate the development of cardiac events and the relation with pre-existent cardiac co-morbidity.
    
    Methods:
    In this retrospective cohort study a thorough patient file search was carried out in 153 patients diagnosed with stage III NSCLC, treated with (chemo-)radiotherapy between 2006 and 2011 in our center. Primary endpoint was the incidence of pre-existing cardiac comorbidity and relation with the development of serious cardiac events, defined as CTCAE 4.0 grade >2, within five years after a curative treatment with (chemo)radiotherapy. Cardiovascular risk prediction was calculated for each patient according to WHO/ISH, which indicates the 10-year risk of a serious cardiovascular event.
    
    Results:
    Pre-existing cardiac comorbidity was seen in 46 patients (31.1%) with most frequently myocardial infarct/ coronary artery disease (9.8%) and arrhythmia (7.8%). WHO/ISH cardiovascular risk prediction was > 10% in 60.1% of the patients. Serious cardiac events appeared in 26% of the patients in the second year after treatment (20.3%). Most frequent cardiac events were arrhythmia (9.2%), myocardial infarction (6.5%), congestive heart failure (4.6%) and pericardial effusion (4.6%).Table:Serious cardiac events within subgroups of the study population

    Conclusions:
    In daily clinical practice 1/3th of patients with stage III NSCLC, treated with (chemo-)radiotherapy, have pre-existing cardiac comorbidity. In addition, 26% develop a serious cardiac event during follow-up, even in patients without cardiac history. Therefor it is important to identify patients at risk in order to prevent these cardiac events.
