[Impact of gestational age and birthweight on long-term cardiovascular health]

Area of Science:

• Perinatal Medicine
• Cardiovascular Physiology
• Developmental Biology

Context:

• Preterm birth and intrauterine growth restriction (IUGR) are associated with long-term alterations in organ development, including the cardiovascular and renal systems.
• Impaired arterial wall structure and properties in infants born with low birth weight, due to preterm birth and IUGR, may contribute to elevated blood pressure and arterial stiffness later in life.
• The precise mechanisms linking adverse perinatal conditions to adult cardiovascular disease remain incompletely understood despite their high prevalence.

Purpose:

• To explore the long-term consequences of intra-uterine growth restriction and preterm birth on cardiovascular health in adulthood.
• To investigate the potential mechanisms by which adverse perinatal conditions affect arterial and renal development.
• To highlight the importance of understanding these associations due to the frequency of preterm birth and IUGR.

Summary:

• Adverse perinatal conditions, including preterm birth and intrauterine growth restriction (IUGR), can induce lasting changes in the arterial system and kidney function.
• These developmental changes, particularly in low birth weight infants, may result in elevated arterial pressure and arterial stiffness in adulthood.
• The underlying mechanisms require further elucidation due to the significant public health implications.

Impact:

• Identifying clinical and paraclinical markers can aid in early detection of cardiovascular risks in individuals with a history of adverse perinatal conditions.
• A better understanding of the link between adverse perinatal factors and adult cardiovascular diseases can inform targeted preventive interventions.
• Improving preventive strategies for cardiovascular diseases in adulthood is essential for this high-risk population.
