Objective: Evaluate the utility of Calgary score for the diagnosis of vasovagal syncope compared with the results of the Tilt table test using sensibilized protocol with medicines. Methodology: Prospective study of diagnostic tests in patients with suspected diagnostic of vasovagal syncope who underwent tilt table test with induced vasodilation with sublingual nitroglycerin. Patients over 18 years were included and patients with documented structural heart disease were excluded. Results: 100 patients were analyzed, averaging 48.7 years of age (SD 19.7), 69% of feminine genre and 4% residents in rural area. Medium of syncope at the moment of tilt table test was 5 (IQR 2-15), with presentation of first episode at 41 years (IQR 21-57), in 52% of the patients triggers were not identified and the clinical manifestations referred in episodes previous to Tilt test were diaphoresis (58%), pallor (55%), dizziness (70%), palpitations (50%) and nausea (42%); during the test dizziness (65%), diaphoresis (19%), nausea (18%) and blurred vision (18%) were reported. A sensitivity of 77.7% was obtained (95% CI 88.8 66.7) and specificity of 40.5% (95% CI 23.3 - 57.7) for the Calgary score. Conclusions: Due to its high sensitivity and easy application, the Calgary score is a useful diagnostic approach instrument for patients with suspected vasovagal syncope and who have a structurally healthy heart, especially in those younger than 50 years.
