RESUMO
Objective To investigate the relationships between level of serum ferritin(SF)/blood lipid and the degree of coronary artery stenosis in elderly patients with acute coronary syndrome(ACS),and evaluate the value of SF in the diagnosis of coronary heart disease. Methods ①One hundred and twenty-five elderly patients with ACS(65 males,60 females)underwent coronary angiography examination,and the total cholesterol(TC), triglycerides(TG),high-density lipoprotein(HDL-C),low density lipoprotein(LDL-C)and SF were determined;according to the results of coronary angiography,the degree of coronary artery stenosis was obtained by using the Gensini score and the degrees of severity of stenosis were divided into three groups:light(42 cases),medium (45 cases)and severe(38 cases). The differences in levels of SF and blood lipids among the three groups were observed,and the relationships between the level of SF/blood lipids and various degrees of coronary artery stenoses were analyzed.②The elderly patients with ACS were divided into two groups,male and female,to compare the SF numerical value and Gensini score between the two groups. ③The SF numerical value and Gensini score of 65 senile male cases with ACS were compared to those of 60 middle aged male cases with the same disease. Results ①Variance analysis showed that SF,TC,LDL-C distribution had significant differences among light,medium and severe groups〔SF(μg/L):147.287±73.838,162.313±94.882,290.421±194.501;TC(mmol/L):4.423±0.900,4.998±0.740, 5.032±1.009;LDL-C(mmol/L):3.150±0.799,3.439±0.839,3.902±1.053,all P0.05);in elderly patients with ACS,SF was positively correlated with Gensini score(r=0.355,P=0.000),while there was no correlation between Gensini score and any one of the following lipids:TC,TG,LDL-C,HDL-C(r=0.090,-0.170,0.256,-0.060,P=0.532,0.092,0.089,0.537).②The comparisons of SF value and Gensini score between senile male and senile female patients with ACS showed no significant differences(all P>0.05).③The comparisons of SF value and Gensini score between senile and middle aged male patients with ACS also showed no significant differences(all P>0.05). Conclusion The occurrence of ACS has certain correlation with SF and lipids,the degree of severity in coronary artery lesion is associated with SF,and there are no differences in age and sex in relation to the value of SF in the diagnosis of ACS.
