BACKGROUND: @entity11924 includes a heterogenous group of @entity1 with @entity951 but normal epicardial coronaries in angiography. OBJECTIVE: Our objective was to study the clinical characteristics of @entity1 with @entity11924 . METHODS: Data of @entity1 who underwent coronary angiography over a period of one year was retrospectively analyzed. Those with normal or non-obstructive coronaries in angiography with @entity662 were included in this study. RESULTS: 1203 @entity1 underwent coronary angiography during the study period. 105 (8.7%) @entity1 fulfilled the inclusion criteria. There were 52 (49.5%) males and 53 (50.5%) females including 31 (29.5%) postmenopausal @entity1 . Many @entity1 had @entity731 risk factors. Typical @entity951 and atypical @entity662 were reported by 63 (60%) and 42 (40%) @entity1 , respectively. ECG was normal in 46 (43.8%) and abnormal in 59 (56.2%) @entity1 . The most common abnormal finding in ECG was @entity1619 changes seen in 49 (46.7%) @entity1 . Regional wall motion abnormality with mild @entity1002 was seen in 4 (3.8%) @entity1 while 101 (96.2%) @entity1 had normal ventricular function in echocardiography. TMT was positive for inducible @entity63 in 35 (33.3%) @entity1 and inconclusive in 10 (9.5%) @entity1 . Angiography showed normal epicardial coronaries in 85 (80.9%) @entity1 . CONCLUSIONS: @entity11924 constitutes a significant subset of @entity1 undergoing coronary angiography. It is essential to identify and treat them specifically for @entity11924 . Many of them have @entity731 risk factors but their presentation is different from those with obstructive coronaries.
