Insights
Peripartum cardiomyopathy (PPCM) risk factors include hypertension, respiratory infection, and elevated high-sensitive C-reactive protein (hs-CRP). Identifying these can aid in PPCM prevention and treatment strategies.
Area of Science:
- Cardiology
- Obstetrics
- Public Health
Background:
- Peripartum cardiomyopathy (PPCM) is a severe form of heart failure with potential mortality.
- Understanding PPCM risk factors is crucial for effective prevention and management strategies.
Purpose of the Study:
- To investigate the clinical characteristics of patients diagnosed with PPCM.
- To identify significant risk factors associated with the development of PPCM.
Main Methods:
- Echocardiography was employed to assess left ventricular ejection fraction (LVEF).
- Blood biomarkers including troponin I (cTNI), high-sensitive C-reactive protein (hs-CRP), and NT-proBNP were quantified.
- Patient data were collected within weeks following delivery.
Main Results:
- PPCM patients were older, had higher blood pressure, and a greater incidence of respiratory infections compared to controls.
- Elevated levels of leucocytes, hs-CRP, cTNI, and NT-proBNP were observed in PPCM patients.
- Independent risk factors identified were elevated hs-CRP (OR=1.86), respiratory infection (OR=2.87), and hypertension (OR=1.68).
Conclusions:
- Hypertension, respiratory infection, and elevated hs-CRP are associated with PPCM development.
- These findings highlight key factors for PPCM pathogenesis in the studied population.
Background:
Peripartum cardiomyopathy (PPCM) is a potentially fatal form of heart failure and the recognition of its risk factors is important for prevention and treatment.
Objective:
To explore the clinical characteristics and the risk factors for PPCM.
Methods:
Echocardiographic was used to examine the left ventricular ejection fraction (LVEF). Blood level of troponin I (cTNI), high sensitive C-reaction protein (hs-CRP), NT-proBNP was measured. All PPCM occurred within weeks following delivery.
Results:
Fifty-two PPCM patients and 52 normal delivery subjects (control group) were included in this study. Compared with the control group, PPCM patients were older, with a higher level of blood pressure, and a higher rate of suspected respiratory infection. The level of leucocytes, hs-CRP, cTNI and NT-proBNP in PPCM patients were higher than in the control. Multivariate logistic regression analysis showed that elevated plasma hs-CRP (OR =1.86, p<0.05), respiratory infection (OR = 2.87, p<0.01), and hypertension (OR =1.68, p < 0.05) were independent risk factors for PPCM. During the follow up of 21.6±5.4 d, one patient (1.9%) died probably of heart failure but other patients remained well.
Conclusion:
Hypertension, respiratory infection, and elevated plasma hs-CRP seem to be associated with the pathogenesis of peripartum cardiomyopathy in this patient population.
