RESUMEN
Objective To analyze the correlation between coronary artery lesion complexity and left ventricular funotion index of patients.Methods A total of 69 patients with coronary heart disease were selected in the study and were divided into low- risk(27 cases),medium-risk(23 cases) and high-risk (19 cases) groups according to the SYNTAX score.The difference in left ventricular function among the three groups were compared by ANOVA, and the correlation between coronary artery SYNTAX score and left ventricular function index was evaluated by Spearman rank correlation analysis.Results The differences in left ventricular end-diastolic volume(EDV),end-systolic volume(ESV),stroke volume(SV),ejection fraction(EF) and muscle mass(MM) among the groups were statistically signifcant (F=7.254,9.181, 13.004, 7.544 and 5.276,P<0.05).The coronary SYNTAX score was negatively corelated with the EF (r=-0.702,P<0.05),but positively correlated with the MM (r=0.638, P<0.05).Conclusion Coronary SYNTAX score is negatively correlated with left ventricular EF, but positively correlated with MM.
RESUMEN
Objective To explore the correlation between serum uric acid level and coronary artery SYNTAX score of coronary heart disease.Methods A total of 69 patients of coronary heart disease were enrolled according to SYNTAX score.The patients were divided into the low risk group (27 cases),medium risk group (23 cases) and high risk group (19 cases).The differences of serum uric acid concentrations among the three groups were compared by ANOVA.Spearman rank correlation analysis was used to analyze the correlation between serum uric acid concentrations and coronary artery SYNTAX scores.Results ANOVA analysis showed that the differences of serum uric acid concentrations among the groups were statistical significant (F=4.74,P＜0.05).The Spearman correlation analysis showed that serum uric acid concentrations were positively correlated with coronary SYNTAX score (r =0.58,P ＜0.05).Conclusion Serum uric acid level and severity of coronary artery disease are positively correlative.
