Cardiac magnetic resonance imaging: insights into developmental programming and its consequences for aging.

Area of Science:

• Cardiology
• Developmental Biology
• Medical Imaging

Background:

• Cardiovascular diseases (CVD) are significant outcomes of adverse perinatal conditions, including fetal hypoxia and maternal malnutrition.
• Cardiac magnetic resonance imaging (CMR) provides extensive physiological data crucial for understanding heart development.
• Understanding these early-life influences is key to preventing adult cardiovascular issues.

Purpose of the Study:

• To review current Cardiac magnetic resonance imaging (CMR) technologies and their applications in studying the cardiovascular system.
• To identify and describe physiological biomarkers measurable by CMR that indicate cardiac dysfunction.
• To explore how CMR aids in understanding developmental pathways leading to impaired cardiac function.

Main Methods:

• Review of existing literature on CMR technologies and their application in cardiovascular research.
• Description of physiological biomarkers assessed by CMR, such as ventricular/atrial function, remodeling, steatosis, and fibrosis.
• Examination of CMR studies in both animal models (e.g., intrauterine growth restriction in baboons) and human subjects.

Main Results:

• CMR can measure key phenotypes related to developmental programming of the heart, including impaired ventricular and atrial function.
• Maladaptive ventricular remodeling, myocardial steatosis, and fibrosis are identifiable using CMR.
• Studies in animal models and humans demonstrate CMR's utility in linking perinatal conditions to cardiac dysfunction.

Conclusions:

• Cardiac magnetic resonance imaging (CMR) is a powerful tool for investigating the developmental origins of cardiovascular diseases.
• CMR facilitates the understanding of dysfunctional adaptations in the cardiovascular system stemming from early life.
• This technology holds significant potential for early detection and intervention strategies for CVD.
