Abstract:
Studies have shown that gout can increase the risk of cardiovascular disease. Three‐dimensional speckle‐tracking echocardiography (3D‐STE), a sensitive imaging technology, enables the detection of subtle myocardial dysfunctions. Our aim is to evaluate the left ventricular (LV) functions in patients with gout using 3D‐STE. Methods 80 subjects: 40 with gout and 40 as normal controls were involved. We obtained and analyzed these parameters from the dynamic images of a 3D full‐volume dataset: global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), Twist, 16‐segmental time‐to‐peak longitudinal strain (TTP) and systolic dyssynchrony index (SDI)besides other relevant parameters. Results Compared with the normal group, gout patients were more likely to have left ventricular remodeling. The patients with gout showed decreased Em, increased E/Em and larger volume index of the left atrium (LAVI) indicating reduced diastolic function. The peak GLS (−17.42 ± 2.02 vs. −22.40 ± 2.57, P 〈 0.001), GCS (−27.04 ± 3.75 vs. −34.85 ± 4.99, P 〈 0.001), GRS (38.22 ± 4.28 vs. 46.15 ± 5.17, P 〈 0.001), and Twist (15.18 ± 5.45 vs. 19.02 ± 5.29, P = 0.015) were significantly lower in patients with gout than in healthy participants. The SDI (5.57 ± 1.46 vs. 4.91 ± 1.19, P = 0.016) was significantly increased in patients with gout compared with normal controls. There was no significant between‐group difference in TTP ( P = 0.43). The systolic GLS, GRS and GCS peak values increased gradually from the base to the apex, with the lowest values in the basal segment in patients with gout. Receiver‐operating characteristic curve analysis revealed among these strains GLS has the largest area under the curve (AUC: 0.93, P 〈 0.001), the cutoff value of −18.97% with a sensitivity and specificity of 80.0% and 92.0%, respectively, for differentiating two groups. A multivariate linear regression analysis shows that the relationship between gout and strain parameters including GLS, GRS, and GCS is statistically significant ( P 〈 0.001). Conclusion Although patients with gout having a normal ejection fraction, structural remodeling of the left ventricle and subclinical LV deformation may occur. 3D‐STE can detect subtle cardiac dysfunctions in patients with gout at an early stage.
