Objective:To investigate plasma levels of fibrinopeptide A(FPA)and platelet alpha-granule membrane glycoprotein 140(GMP-140), and to analyze the changes of coagulation activity in elderly patients with primary microvascular angina(PMVA).Methods:In this prospective case-control study, a total of 45 elderly patients(aged 60-80 years, 27 males and 18 females)admitted to our hospital from Jan.2019 to Dec.2020 were diagnosed as PMVA(as microvascular angina group)by clinical symptoms, electrocardiogram, dynamic electrocardiogram and coronary angiography.Forty-three age-and sex-matched elderly subjects who took a medical check-up and had no primary microvascular angina were included as the control group.Plasma levels of FPA, GMP-140 and high-sensitivity C-reactive protein were determined.The levels of systolic blood pressure, diastolic blood pressure, platelet, fasting blood glucose, triglyceride, total cholesterol, high-density lipoprotein and low-density lipoprotein, uric acid, renal function and liver function were detected.Results:The FPA level was higher in the PMVA group than in the control group[(430.32±364.05)μg/L vs.(263.73± 118.29)μg/L, t=2.913, P<0.01]. There was no difference in GMP-140 level between the PMVA group and the control group[(5.78±3.92)μg/L vs.(6.95±1.91)μg/L, t=-1.790, P>0.05]. The high-sensitivity C-reactive protein level was higher in the PMVA group than in the control group[(3.33±5.70)mg/L vs.(0.81±0.86)mg/L, t=2.927, P<0.01]. Conclusions:Compared with the control group, the FPA level is significantly increased with elevated coagulation activity in patients with primary microvascular angina.The increased inflammatory state in the PMVA group might promote the occurrence and development of microvascular angina, but whether the inflammatory state promotes the enhancement of coagulation activity needs further study to confirm.

Objective To investigate the effect of different etiology on the serum level of carbohydrate antigen 125 (CA125) in elderly patients with chronic congestive heart failure (CHF), and to assess any correlation of CA125 with serum level of B-type natriuretic peptide (BNP). Methods The 155 aged patients with New York Heart Association (NYHA) class Ⅲ or Ⅳ were enrolled and grouped into four reasons of hypertension, coronary heart disease (CHD), cardiomyopathy and other reasons, and 25 healthy old persons as control.CA125 and BNP levels were measured by automatic chemiluminescent immunoassay and enzyme immunoradiometric assay, respectively. Results CA125 level in patients with CHF was (83.4±6.6)U/L for hypertension, (36.8±1.4)U/L for CHD, (38.1±1.6)U/L for cardiomyopathy and (38.4±1.4)U/L for other reasons, which significantly higher than for healthy controls [(14.3±1.15) U/L, P＜0.05].Especially, CA125 level in hypertension group was notable higher than in other reasons of group (P＜0.05), and was positively related to BNP level (r=0.67,P＜0.05). Conclusions Serum CA125 level is a predictor for clinical pathogen of CHF.Therefore, it may be a useful additional marker for the evaluation of clinical treatment of these patients

Objective:To investigate the diagnostic value of plaque type and nature of coronary artery angiography in patients with coronary heart disease.Methods:The clinical data of 80 patients with coronary heart disease in Hangzhou Red Cross Hospital were retrospectively analyzed.According to the CT value of plaque, 20 cases were classified into calcified plaque group (CT value ≥130 HU) and soft plaque group (CT value ≤60 HU). Mixed plaque group (CT value 60-130 HU) had 40 cases.The association between coronary stenosis and plaque type, platelet function, serum biochemical and adipocytokine indicators were compared among the three groups.Results:There was a certain correlation between the proportion of different types of plaque and the degree of stenosis.There were 12 cases of mild stenosis, 3 cases of moderate stenosis and 5 cases of severe stenosis in calcified plaque group, 11 cases of mild stenosis, 14 cases of moderate stenosis and 15 cases of severe stenosis in mixed plaque group, 2 cases of mild stenosis, 7 cases of moderate stenosis and 11 cases of severe stenosis in soft tissue plaque group, the difference was statistically significant (χ 2=13.27, P<0.05). Comparison of platelet function, the calcified plaque group, mixed plaque group and soft tissue plaque group had no statistically significant difference in platelet count (PLT) ( F=1.56, P>0.05). The PDGF-BB, TEG-MA and P-selectin levels in the soft tissue plaque group were higher than those in the mixed plaque group and the calcified plaque group, the differences were statistically significant ( F=11.57, 6.47, 18.74, all P<0.05). As to the adipose cytokines, the levels of CRP, IL-6, IL-12, leptin and SFRP5 in the soft tissue plaque group were higher than those in the mixed plaque group and the calcified plaque group, the differences were statistically significant( F=7.95, 21.31, 14.58, 9.37, 13.58, all P<0.05). Conclusion:Coronary CT angiography can evaluate the severity of coronary heart disease by evaluating the type of plaque, and provide a theoretical basis for clinical treatment.It is worthy of clinical promotion.
