Outcomes and complications of peripartum cardiomyopathy: protocol for a systematic review and meta-analysis
Abstract
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…
