Uric Acid is Neither the Risk Factor nor Prognostic Factor for 3-year Clinical Events in Vasospastic Angina Patients Regardless of Gender
- Abstract
- Background: It has been reported that a major cause of vasospastic angina is endothelial dysfunction of the coronary artery. However, it is controversial whether the uric acid level is associated with vasospastic angina, and can be a prognostic factor for vasospastic angina. Methods: A total 3828 patients (pts) underwent coronary angiography with acetylcholine (Ach) provocation test from Mar 2004 to Sep 2012 were enrolled. The definition of positive coronary artery spasm (CAS) was defined as transient luminal narrowing more than 70%. The uric acid level was categorized into 4 quartile groups; less than 3.8, 3.9~4.7, 4.8~5.7, and more than 5.8 mg/dL. Major adverse cardiovascular events (MACEs) defined as the composite of recurrent chest pain, cardiac death, myocardial infarction, and cerebrovascular accident were valuated up to 3 years. Results: The follow-up rate was the 61.1% (2340/3828). There was no difference in uric acid level between negative and positive CAS groups in female gender but in male gender, uric acid level was higher in negative CAS group (Table 1). However, when adjusted by age, the difference was disappeared (OR, 0.965; 95% CI, 0.898-1.037; P-value, 0.335). The incidence of MACE was 11.1% in male gender and 8.6% in female gender. In male gender, the serum uric acid level between the groups with and without MACE was similar but in female gender, the uric acid level was higher in the group with MACE. However, when adjusted by age, uric acid was not associated with MACE (Table 2). Conclusions: In our study, uric acid was neither the risk factor nor prognostic factor for 3-year clinical events in CAS patients regardless of gender.
