About

The purpose of this study is to investigate whether exposure to hypertensive disorders of pregnancy and/or a preterm birth results in alterations in the cardiovascular system during infancy.

Full description

While the incidence of cardiovascular disease has reduced dramatically, coinciding with favourable changes in risk factors, cardiovascular disease remains the single largest cause of mortality and premature mortality in the United Kingdom. Identification of novel biological pathways that underlie disease susceptibility raises the potential for new early primary prevention strategies to complement classical management. There is particular interest in the role of early environment in 'programming' risk of cardiovascular disease in later life and growing evidence that various early life exposures impact cardiovascular health in the longer term. The investigators have therefore designed the EPOCH study to investigate whether those individuals born to hypertensive pregnancies and/or to a preterm birth demonstrate differences in the cardiovascular phenotype at birth, or whether they develop any differences over the first three months of life and whether this varies with other perinatal factors. This study also allows investigation of the short term impact of perinatal interventions used in this cohort. Comprehensive multi-modality non-invasive imaging measures of cardiovascular structure and function allow precise quantification of cardiovascular phenotype in this population.

Inclusion criteria

  • Available for assessment within the neonatal period,
  • Parent is willing and able to give informed consent for participation in the study,
  • Physical condition is suitable to allow non-invasive vascular testing,
  • Mother meets criteria for inclusion in the study and is willing to participate in the study. (Aged >/= 16 years and Is able and willing to give informed consent for participation in the study, and is able and willing to give informed consent for her infants participation in the study. )
  • Cases: Diagnosed during pregnancy with preeclampsia or gestational hypertension and/or delivered preterm (<37 weeks gestation)

Exclusion criteria

  • Parent is unwilling to give consent,
  • Unavailable for assessment of cardiovascular system,
