Maternal and Perinatal Outcomes of Pregnancies Complicated by Chronic Hypertension Followe

A retrospective cohort study from a referral hospital assessed 385 pregnant women with chronic hypertension over a 5-year period (2012-2017). The data, collected by Gabriela Pravatta Rezende via medical chart review, describes maternal demographics, preeclampsia prophylaxis, and birth outcomes. Key findings include a 40% rate of superimposed preeclampsia and a mean gestational age at birth of 36 weeks.

Use Cases

• Modeling risk factors for superimposed preeclampsia based on patient demographics and medical history described in the abstract.
• Analyzing associations between preeclampsia prophylaxis (aspirin/calcium) and severe maternal outcomes like HELLP syndrome.
• Studying neonatal complication rates in pregnancies complicated by chronic hypertension and prematurity.

Strengths

• Includes data from 385 patient records, providing a substantive cohort size for analysis.
• Covers a 5-year time period (2012-2017), allowing for temporal trend observation.
• Contains specific clinical outcome frequencies, such as a 40% rate of superimposed preeclampsia and a 17% rate of pre-existing organ damage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• Data may reflect geographic and institutional bias inherent to a single referral center study.
