Bochum“, Bochum, GERMANY4, St. Josef-Hospital, Ruhr University Bochum, Bochum, GERMANY5 Background: A common phenomenon of public stroke awareness campaigns is that such events usually attract elder participants who are often well informed about their vascular risk profile. To address a target group who is probably not aware of their existing risk factors, we performed a stroke awareness campaign during a football game of the German Bundesliga. To evaluate the usefulness of such an approach, we randomly assessed the stroke risk profile of some of the football fans. Methods: Before the match, information materials about stroke risk factors and symptoms and questionnaires to assess the stroke risk profile were distributed in the fan section of the Bundesliga Club “VfL Bo-chum”. Blood pressure was measured randomly in some of the football fans before the match as well as in the half-time break. They were classified hypertensive according to the criteria of the Ger-man Hypertension League. Results: Fourty-five football fans (mean age=38+/-12y; 4 female) could be evaluated. The blood pressure readings ranged from 100/70mmHg to 190/100mmHg (mean=131/87mmHg). Before the match, 71% of the football fans revealed elevated blood pressure values. After the reassuring 1-0 lead for “VfL Bochum” only 47% of the supporters remained hypertensive. Conclusion: Hypertension as a major risk factor for stroke was detected in more than half of our football fans. The majority of these predominantly young to middle-aged people were unaware of the existence of this risk factor. Thus, such awareness campaigns could provide a new and good primary preventive approach. A relationship between a victory of “VfL Bochum” and a reduction in stroke risk to ist supporters remains speculative. 436 © 2013 S.

As a complement to clinical decision in AF patients cardioembolic risk scores have been developed. Recently a new score was proposed (CHA2DS2-VASc) and de-spite being validated for wide heterogeneous cohort of patient with AF its’ specific validity in the setting of secondary stroke prevention is not completely ascertained. Transesophageal echocardiog-raphy (TEE), due to its high sensitivity assumes a particular importance in identifying a cardioem-bolic source. We aim to study the differential contribution of cardioembolic risk scores (CHADS2 and CHA2DS2VASc) as predictors of cardioembolic source documented by TEE in secondary stroke prevention. Methods: CHADS2 and CHA2DS2VASc were applied to all patients that performed TEE within the first 5 days of ischemic stroke due to AF during 8 months. We defined active cardioembolic source (ACS) as the observation in TEE of spontaneous autocontrast in left auricle/auricular appendix or thrombi in the left cardiac chambers. Receiver Operating Characteristic (ROC) curves were per-formed to determine the cut-off point of each score for ACS, their sensitivity and specificity. Results 95 patients were analysed, 65.3% male, mean age 63.7 years (SD: 14.5). 20 patients (21.1%) had ACS. ROC curve identified CHADS2 of at least 4; area under curve (AUC): 0.73, sensibili-ty: 75.0%, sensitivity: 76.0%, p=0.014 and CHA2DS2VASc of at least 5; AUC: 0.75, sensitivity: 83.3%, specificity: 58.0%, p=0.009 as predictors of ACS. Conclusion: Both scales show good sensibility as predictors of cardioembolic risk in secondary stroke prevention. CHA2DS2VASc has a superior sensibility than CHADS2, being however less specific.
