AB  - Electrocardiogram (ECG) plays a major role in the study of chest pain. To measure the impact of making an ECG in patients with Chest Pain (CP) in primary care. We conducted a retrospective cohort study of patients with CP that made an ECG in a primary care setting by comparison with those who made the ECG as a routine test in order to measure the change of cardiovascular clinical guidance up to 6 months after ECG. Cases were categorized in atypical or typical CP. Secondary a clinical practice analysis was performed, counting the number of medical visits 12 months before and after ECG. We studied 480 patients, consecutively selected during 4 years, 333 in CP group (286 with atypical CP) and 147 controls. Patients with typical CP presented higher changing in clinical guidance (RR = 4.299; 95% CI: 2.378-7.772, p<0.001) than patients with atypical CP (RR = 1.116; 95% CI: 1.008-1.235, p = 0.047) when compared with controls. In the routine group, there wasn’t any variation of visits counting as in the typical CP group but a reduction of 0.59 visits (95% CI: -0.90-0.29; p<0.001) occurred in the atypical CP patients 1 year after the ECG. Anxiety was significantly associated to atypical CP orientation.
