ABSTRACT

BACKGROUND: Internet has become a significant resource for dissemination of medical information. We sought to investigate prevalence and usage patterns of Internet access among consecutive patients with cardiovascular diseases. METHODS: A cross-sectional study was performed using a questionnaire as study tool. Among patients with Internet access, the type of health information sought and the impact of these on daily life were assessed. RESULTS: Of 1063 patients invited to the study, 1000 patients [68% male gender, mean age 66 ± 11 years (range 27-83 years)] agreed to complete the questionnaire. 216/1000 (21.6%) used Internet to obtain information related to their disease. The patient education was graded as: low (15%), medium (66%) and high (19%). Reasons for Internet use were as follows: 24-h availability 142/216 (65.7%); free of charge 58/216 (26.9%); and anonymity 50/216 (23.2%). Younger (≤ 66 years) age (35.2% vs. 15.3%; p = 0.0001), male gender (24.6% vs. 15.4%; p = 0.001) and higher education level (49.4% vs. 16.1%; p = 0.001) were significantly associated with Internet use. 30.6% (66/216) of Internet users changed their individual health behaviour attributable to information found on the Internet. However, this was not related to age, gender or level of education (p = 0.5, p = 0.6 and p = 0.4, respectively). Patients without Internet use obtain health information mainly from the pharmacist (62%) or from their treating physician (58%). CONCLUSIONS: A relevant number of patients with cardiovascular disease access the Internet for health information. The impact of such information on health-related behaviour in daily life was low.

ABSTRACT

BACKGROUND: Interpretation of prehospital 12-lead electrocardiograms (ECG) in acute ST-elevation myocardial infarction (STEMI) remains a diagnostic challenge in many cases. The aim of this study was to determine whether board-certified emergency physicians (BCEP) are able to distinguish STEMI from non-STEMI in a large proportion of cases, thus assuring more precise prehospital triage and treatment. METHODS: Electrocardiograms of eight patients with acute non-traumatic chest pain (with 6 ECGs demonstrating STEMI, one with pericarditis, and one with pulmonary embolism) were assessed in a blinded fashion by 73 BCEP (19 female, mean age 37 +/- 5.3 years). Decisions had to be made by them regarding the diagnosis (STEMI or not) and treatment (immediate reperfusion or transfer to the nearest hospital without facilities for percutaneous coronary intervention). RESULTS: In the ECGs with STEMI 83% of BCEPs made the correct diagnosis without significant differences between the subgroups. But in cases of non-STEMI-ECG only 30% of BECP made the correct diagnosis. The results in interpreting non-STEMI were better in older (> 50 years) BCEPs and in those with a background in internal medicine (p = 0.045, and p = 0.01, respectively). In case of STEMI 75% of BCEPs initiated the correct therapy, without significant differences between the subgroups. In case of non-STEMI ECG only 33% of BECPs made the correct diagnosis. Also, the therapeutic decisions in case of non-STEMI were better in older (> 50 years) BCEPs and in those with a background in internal medicine (p = 0.04, and p = 0.02 respectively). CONCLUSION: In cases of acute non-traumatic chest pain the interpretation of the electrocardiogram by prehospital emergency doctors give to unsatisfactory results. The present study suggests, that additional training in ECG interpretation may be a critical component of the education of physicians who care for patients presenting with acute coronary syndrome.

ABSTRACT

BACKGROUND: Sustained, stable wide QRS-complex tachycardia (WCT) remains a diagnostic challenge, because the treatment of supra-ventricular tachycardia (SVT) with aberrant conduction differs considerably from that of a ventricular tachycardia (VT). A usual recommendation for treating a case of a stable WCT is to manage it as if it were VT, in accordance with the consideration of "first do no harm". The aim of this study was to determine whether Board-certified emergency-physicians are able to differentiate VT from SVT with aberrant conduction in a high percentage of cases (> 90%), thus to assure more precise prehospital treatment." METHODS: Eight electrocardiograms with WCT (four with electrophysiologically proven VT or SVT, respectively) were evaluated in a blinded fashion by 64 Board-certified emergency-physicians (23 female, 41 male, mean age: 37,8 + 5,1 years). Initially, the diagnosis had to be made without any further information. Afterwards the same electrocardiograms were presented again, providing important additional information. RESULTS: 55% of the study population were able to establish the correct diagnosis merely by evaluating the electrocardiogram. Providing the above mentioned additional information, the number of correct diagnoses increased to 61%. These results were roughly similar in all subgroups, only the subgroup of cardiologists showed a trend to better results with correct diagnoses in 68% without and 73 % with additional information. None of the subgroups reached the pre-specified cut-off of > or = 90% correct diagnoses. Specialist status as well as experience in emergency medicine had no significant influence on the results, only the subgroup of emergency physicians with an experience of more than five years showed a trend towards a higher rate of correct diagnosis, compared with the subgroup with less than one year experience in emergency medicine. CONCLUSION: In cases of stable WCT the evaluation of the electrocardiogram without further information in prehospital emergency-medicine leads to unsatisfactory results. The correct diagnosis in WCT can be improved by using additional data but the diagnostic accuracy is still low. Therefore, the differential diagnosis of stable WCT in preclinical emergency-medicine cannot be recommended. Until proven otherwise, any stable WCT should be managed as if it were VT.

ABSTRACT

Tetralogy of Fallot is the most common cyanotic cardiac malformation in late childhood and adult, occurring in approximately 0.25 of 1000 live births. Most patients undergo early surgical correction. Therefore, the natural history of this disease has been evaluated in only a few cases. We report a complex case of a tetralogy of Fallot, who reached the age of 74 years without surgical or medical treatment and who was transferred to our clinic after syncope due to ventricular tachycardia.
