ABSTRACT
Objective To explore the effect of inflammation and autoimmunity in peripartum cardiomyopathy(PPCM). MethodsA total of82 PPCM patients and 100 normal delivery patients were randomly selected and conducted epidemiological survey.High-sensitivity Creaction protein(hs-CRP),troponin I,human antimyocardial antibody IgG(AMA-IgG),Coxsackie B virus IgG(CBV-IgG)and adenovirus antibody IgG(ADV-IgG)were detected with ELISA. ResultsCompared with control group,PPCM patients had older age,higher pressure,higher proportion of cesarean section and infection.The levels of serum hs-CRP,cTNI,and leucocyte were markedly higher in PPCM patients compared with control.The positive proportion of AMA-IgG and CBV-IgG was significantly increased(P<0.01)in PPCM patients compared with the control.Logistic regression showed that infection(OR=2.87,95%CI 1.15-5.24),increased hs-CRP(OR=1.86,95%CI 1.08-4.02)and positive AMA-IgG(OR=2.68,95%CI 1.19-4.85)were independent risk factors for PPCM. ConclusionsInflammation and autoimmunity play an important role in peripartum cardiomyopathy.
ABSTRACT
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.
ABSTRACT
Objective To explore the effect of spironolactone on vascular remodeling of injuried rabbit artery. Methods 20 male New Zealand rabbits were randomly divided into two groups. The rabbit models of iliac artery angioplasty were set up by BC. After injury, control group was fed with standard forage, and experimental group was fed with standard forage and spironolactone(20mg?kg~ -1?d~ -1). The rabbits were killed four weeks after injury. The injuried segments of iliac artery were removed, and processed for histological and morphological analysis by imumohistochemistry and TD 2000 analysis system of pathology image. Results AUIEM and AUEEM in the experimental group significantly increased as compared with the control group(P0.05). Conclusion Spironolactone could improve vascular remodeling after angioploasty of iliac artery in rabbits.
