Clinical characteristics of chronic total occlusion in elderly patients of different genders / 中国综合临床

ABSTRACT

Objective To investigate the metabolic characteristics of chronic total occlusion (CTO) in different sex elderly patients. Methods A retrospective analysis was performed on three hundred and sixty-two cases from Beijing Anzhen Hospital with CTO,including 226 cases in the male group and 136 cases in the female group. The characteristics of metabolic risk factors were compared and analyzed between the two groups. Results (1)The level of the systolic blood pressure (SBP)((135. 62±19. 67)mmHg vs. (129. 08±14. 13)mmHg), total cholesterol (TC)((4. 39±0. 95) mmol/ L vs. (3. 91±0. 93) mmol/ L)、low density lipoprotein cholesterol (LDL-C)((2. 56±0. 80) mmol/ L vs. (2. 23±0. 70) mmol/ L) in the female group were significantly higher than those of the male group,the differences were statistically significant (t = -2. 594,P = 0. 010;t = -3. 341,P= 0. 001;t= -2. 893,P = 0. 004) . (2) The level of urea acid (UA) ((368. 95±75. 96) μmol/ L vs. (326. 20 ±83. 27)μmol/ L) and ratio of smoking ( 61. 95% ( 140/ 226) vs. 5. 88% ( 8/ 136)) in the male group were significantly higher than those in the female group(t= 3. 440,P= 0. 001;χ2 = 55. 211,P= 0. 000). Conclusion The higher levels of systolic pressure,total cholesterol and low density lipoprotein cholesterol are the metabolic clinical characteristics of elderly female CTO patients,and the elevated uric acid and smoking are metabolic clinical characteristics of elderly male CTO patients.
