围生期心肌病发病相关因素的研究

Objective To explore the risk factors of peripartum cardiomyopathy (PPCM). Methods A total of 82 PPCM and 100 normal delivery females were randomly recruited in the current study. Echocardiographic, cTNI,high sensitive C-reaction protein(hs-CRP) ,NT-proBNP were measured. Fifty-two patients were followed up for a mean of 6 months. Results The PPCM patients (29. 5 ± 6. 4) yrs were older than the controls (25. 2 ± 5. 8) yrs (P<0.01) . Compared to the controls, the PPCM patients showed higher blood pressure (146.9/98. 8 mm Hg v. s. 130. 2/80. 1 mm Hg, P < 0. 01) , higher proportion of cesarean section (65. 9% v. s. 51. 0% , P < 0. 05) and complicated infection(75. 6% v. s. 10. 0% ,P <0. 01). The level of leucocyte(11.0 × 109/L) ,cTNI(0. 17 μg/L), hs-CRP(28. 2 mg/L)and NT-proBNP(650. 1 ng/L) were significantly higher in the PPCM patients compared with control(8. 8 × 109/L,0. 06μg/L,6. 2 mg/L and 110. 5 ng/L,P <0. 01). Hs-CRP was positively related with NT-proBNP(r = 0. 67, P < 0. 01). After average of 6 months of treatment, left ventricular ejection fraction enhanced from 32. 2% to 50. 6%. NT-proBNP significantly declined from 650. 1 ng/L to 225.6 ng/L(P <0. 01). Multiple linear regression analysis showed that diastolic pressure (P < 0. 05), LVED (P < 0. 05) and hs-CRP (P < 0. 05) were the independent predictors for declined NT-proBNP. Conclusions Inflammatory plays an important role in the development of peripartum cardiomyopathy.
