RESUMO
RATIONALE: Though it is rare, isolated interrupted aortic arch (IAA) could lead to hypertension. Surgical repair is the only effective curative method to treat IAA conditions and patients with IAA can hardly survive to adulthood with medication alone. We report an IAA case that of a 45-year-old male patient who survived for 45 years without surgical treatment. PATIENT CONCERNS: A 45-year-old man was referred to the hospital presenting with abnormal blood pressure level. Both computed tomography angiogram (CTA) and angiography revealed IAA. DIAGNOSES: The patient was diagnosed as IAA based on computed tomography angiogram (CTA) and angiography. INTERVENTIONS: The patient's blood pressure was severely high and refractory. He refused surgical treatment and accepted antihypertensive medication for 10 days. OUTCOMES: The patient's office blood pressure level was abnormal, fluctuating between 140/90 and 160/100 mm Hg, but 24-hour ambulatory blood pressure monitoring showed normal level. LESSONS: Hypertension due to IAA could be controlled with medications, even surgery is not performed. The discrepancy between ambulatory and office blood pressure levels may be due to the white coat effect.

OBJECTIVE: The Veterans Specific Activity Questionnaire (VSAQ) has been used to assess exercise tolerance. Nevertheless, there is no validated Chinese version. The aim of this study is to determine whether a questionnaire-based method using the Chinese version of VSAQ (the modified VSAQ) is a practical tool to assess exercise tolerance of Chinese elderly with coronary heart disease. METHODS: One hundred thirty consecutive elderly patients who were diagnosed with coronary heart disease (CHD) (mean age 68.9 ± 6.0 years) referred for treadmill exercise testing (TET) for clinical reasons were included in the study. They were asked to complete a questionnaire for clinical characteristics information on age, sex, history, exercise habits, medications, the original VSAQ and the modified VSAQ. We investigated the relationship between exercise tolerance in metabolic equivalents (METs) estimated by VSAQ and that obtained by TET. RESULTS: The METs by the original VSAQ and the modified VSAQ did not difference significantly (P = 0.528). The modified VSAQ scores were significantly correlated with the METs obtained by TET (r = 0.819, 95% CI: 0.753-0.873, P < 0.01), and the scores of original VSAQ also correlated with the METs by TET (r = 0.804, 95% CI: 0.745-0.854, P < 0.01). The Bland-Altman graph analysis showed few values outside the limits of agreement, suggesting good precision between the METs estimated by questionnaire and the METs obtained by TET. CONCLUSIONS: The Chinese version of the VSAQ confirmed its validity and equivalence to the original version, especially when evaluating individuals with coronary heart disease and older adults. The results showed that the VSAQ is a valuable tool to assess the exercise tolerance.
