Maternal hypercholesterolaemia during pregnancy affects severity of myocardial infarction in young adults

Eur J Prev Cardiol. 2022 May 5;29(5):758-765. doi: 10.1093/eurjpc/zwab152.


Aims: Elevated maternal cholesterol during pregnancy (MCP) enhances atherogenesis in childhood, but its possible impact on acute myocardial infarction (AMI) in adults is unknown.

Methods and results: We retrospectively evaluated 310 patients who were admitted to hospital and whose MCP data were retrievable. Eighty-nine AMI patients with typical chest pain, transmural infarction Q-waves, elevated creatinine kinase, and 221 controls hospitalized for other reasons were identified. The AMI cohort was classified by MI severity (severe = involving three arteries, left ventricle ejection fraction ≤35, CK-peak >1200 mg/dL, or CK-MB >200 mg/dL). The association of MCP with AMI severity was tested by linear and multiple regression analysis that included conventional cardiovascular risk factors, gender, age, and treatment. Associations of MCP with body mass index (BMI) in patients were assessed by linear correlation. In the AMI cohort, MCP correlated with four measures of AMI severity: number of vessels (β = 0.382, P = 0.001), ejection fraction (β = -0.315, P = 0.003), CK (β = 0.260, P = 0.014), and CK-MB (β = 0.334, P = 0.001), as well as survival time (β = -0.252, P = 0.031). In multivariate analysis of patients stratified by AMI severity, MCP predicted AMI severity independently of age, gender, BMI, and CHD risk factors (odds ratio = 1.382, 95% confidence interval 1.046-1.825; P = 0.023). Survival was affected mainly by AMI severity.

Conclusions: Maternal cholesterol during pregnancy is associated with adult BMI, atherosclerosis-related risk, and severity of AMI.
