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.
