The risk of developing cardiovascular diseases following HDP is high. Arterial stiffness is a prognostic indicator for cardiovascular disease in the general population, and it is elevated during pregnancy in women with HDP. No systematic reviews have been conducted to determine if arterial stiffness remains elevated beyond puerperium in these women with HDP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>We will conduct a systematic literature search in the following electronic databases: Medline, PubMed, Embase, Cochrane Library, Google Scholar, Web of Science and CINAHL. The review will consider studies that investigate arterial stiffness in women who had HPD and are between 43 days and 10 years postdelivery and under 60 years of age. This systematic review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols guidelines. Estimates of mean \u00b1 SD for arterial stiffness indices (cfPWV, AIx and AIx@75) for the women in the included studies will be obtained. For studies where the estimates were reported as the median and IQR, approximate estimates of mean \u00b1 SD will be calculated by using the low and high end of the range, median and sample size. Data from the individual studies will be pooled by use of a random-effects model. The risk of bias assessment will be assessed using the Cochrane Collaboration tool and the Newcastle-Ottawa Quality Assessment Scale as appropriate. Sources of heterogeneity will be explored by sensitivity and subgroup analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>No ethics approval is required as only published data will be used in this study.
