RESUMO

OBJECTIVE: To assess the validity of the short version of the WHO/Rose angina questionnaire in Portuguese, applied to adults aged 40-74 years, living at Butantã, reference area of the Hospital Universitário - Universidade de São Paulo, in Brazil using exercise treadmill test and pharmacological stress echocardiography as gold standard. To analyze if the association of the American Thoracic Society (ATS) dyspnea questionnaire to the WHO/Rose angina questionnaire modifies de sensitivity, specificity, accuracy, positive (PPV) and negative (NPV) predictive values, positive (PLR) and negative (NLR) likelihood ratios. METHODS: The short version of the angina questionnaire adapted and translated into Portuguese has three first questions to characterize exertional chest pain. It was applied to 116 individuals classified into low- and high-risks groups according to the Framingham score, using the exercise treadmill test as the gold standard. Pharmacological stress echocardiography was used as the gold standard in a group of 74 participants. Sensibility, specificity, accuracy, PPV, NPV, PLR and NLR were calculated. The PRIME-MD was used to diagnose anxiety and depression. The translated version of the dyspnea questionnaire of the American Thoracic Society (ATS) was also employed. RESULTS: The frequency of angina was 8.7%, similar to that found in other studies, and of 4.8% for ischemia, which is similar to the general population of the city of Sao Paulo. Among 126 participants, 116 individuals had a conclusive exercise treadmill test; 44 subjects in the high-risk group had a mean Framingham score of 9.3 (2.5) and mean age of 53.6 (7.0) years these figures are higher as compared to 72 individuals of the low-risk group, with a score of 3.3 (3.0) (p=0.000) and mean age of 49.2 (7.3) years (p=0.002). Most cases of ischemia were in the low-risk group. Out of 126 participants, 88 were submitted to the stress echocardiography and it was conclusive in 74, 29 subjects in the high-risk group had a mean Framingham score of 9.4 (2.7) and 45 of the low-risk group had a score of 3.4 (3.4) (p=0.000). The angina questionnaire was compared to the exercise treadmill test and presented sensibility of 25.0%, specificity of 92.0%, accuracy of 89.7%, PPV of 10.0%, NPV of 97.2%, PLR of 3.1 and NLR of 0.82. There was no case of ischemia on stress echocardiography associated to a positive angina questionnaire. The frequency of anxiety was 18.3% and of depression was 13.5%, there was association among presence of the depression and anxiety as questionnaire defined with angina presence the assessed by the OMS/Rose angina questionnaire (p=0.076). No participant with dyspnea presented signs of ischemia on exams. CONCLUSION: The short version of the angina questionnaire translated into Portuguese has quality parameters of test that are similar to those of other studies with larger samples, that is, low sensibility and high specificity and its utilization depends on the study objectives. The mental disorders assessed were associated with positive angina questionnaire. Dyspnea was not a myocardial ischemia equivalent symptom in studied sample
