Correlation Analysis Between The Coronary Slow Flow And Heart Rate Variability

Objective: To investigate the relationship between coronary slow flow and heart rate variability.Methods: Selection in February 2010- February 2014, the second hospital affiliated to fujian medical university cardiovascular internal medicine diagnosis of coronary slow flow of 180 cases of patients, in addition to select 120 cases of patients with normal coronary flow as the control group, collecting clinical baseline conditions、heart rate variability and the result of coronary angiography, and carries on the correlation analysis.Results:(1) by comparing the two groups of patients with conventional index changes, the results show that two groups of uric acid, TC/HDL and LDL/HDL levels have significant difference(P < 0.05), while other indicators have no significant difference(P < 0.05);(2) compare the observation group and control group with HRV level, the results show that HRV each index in observation group were significantly lower than the control group, the differences were statistically significant(P < 0.05);(3) by comparing the observation group and control group, coronary angiography results found that group of each vessels of coronary arteries TIMI flow frames(TFC), rectify the LAD, and three vascular blood flow to the average frames(TFC) were higher than control group(P < 0. 05), the difference was statistically significant.Conclusion: Slow coronary blood flow and blood uric acid in patients with normal, HCY, TC/HDL and LDL/HDL levels have obvious difference, the indicators HRV coronary slow flow group were obvious decline and the incidence of cardiovascular events is higher than the control group, HRV may as risk prediction in patients with coronary slow flow of one of the main indicators.
