Insights
This systematic review protocol outlines a plan to analyze peripartum cardiomyopathy (PPCM) complications and outcomes. It aims to provide a comprehensive summary of maternal morbidity and mortality associated with PPCM.
Area of Science:
- Cardiology
- Obstetrics
- Public Health
Background:
- Peripartum cardiomyopathy (PPCM) is a significant cause of maternal morbidity and mortality globally.
- PPCM is associated with severe complications, particularly in the early disease stages, including heart failure, arrhythmias, and thromboembolism.
Purpose of the Study:
- To conduct a systematic review and meta-analysis to summarize available data on complications and outcomes in women with PPCM.
- To report the burden of complications around diagnosis and 6- or 12-month outcomes for PPCM patients.
Main Methods:
- A comprehensive literature search will be conducted across major databases (PubMed/MEDLINE, Web of Science, Scopus, EBSCO Host) for studies published from 2000 to June 2021.
- Inclusion criteria encompass cohort studies, cross-sectional studies, and control arms of RCTs reporting PPCM complications and outcomes.
- Risk of bias assessment and statistical heterogeneity testing (I², χ²) will be employed to ensure data quality and reliability.
Main Results:
- This section will present pooled analyses of complications and outcomes from multiple centers, regions, and continents.
- The study will quantify the incidence of various complications and their impact on maternal health.
- Six-month and 12-month outcomes for women diagnosed with PPCM will be detailed.
Conclusions:
- This systematic review and meta-analysis will enhance understanding of PPCM-related complications and outcomes.
- The findings will inform clinical practice and guide management strategies for PPCM.
- A global perspective on PPCM burden will be provided, aiding in improved maternal healthcare worldwide.
Introduction:
Peripartum cardiomyopathy (PPCM) remains a major contributor to maternal morbidity and mortality worldwide. The disease is associated with various complications, which occur predominantly during the early stages of the disease. Adverse outcomes include decompensated heart failure, thromboembolic complications, arrhythmias and death. We present a protocol for a systematic review and meta-analysis to summarise the available data on the complications and outcomes of women with PPCM.
Methods And Analysis:
A comprehensive search of all articles published between 2000 (the year in which the first universal definition of PPCM was used) and 1 June 2021 will be performed on PubMed/MEDLINE, Web of Science, Scopus and EBSCO Host, including Academic Search Premier, Africa-Wide Information, Cumulative Index to Nursing and Allied Health Literature. All cohort and cross-sectional studies, as well as control arms of randomised control trials (RCTs) reporting on the complications and outcomes of PPCM will be included in the review. Methodological quality assessment of included studies will be done by assessing the risk of bias. Heterogeneity of the data will be tested by visual inspection of the forest plot and I2 and χ2 tests. This study will report the burden of complications occurring around the time of diagnosis as well as the 6-month or 12-month outcomes of women with PPCM. A summarised description in form of a pooled analysis of across multiple centres, regions and continents would help us to better understand the estimates of complications and outcomes of women with PPCM.
Ethics And Dissemination:
As this research is a systematic review of published literature, ethical approval is not required. The results will be reported according to the latest guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement, and will be submitted to a peer-reviewed journal.
