Cardiovascular functional and structural changes in children with primary hypertension.

Area of Science:

• Pediatric Cardiology
• Vascular Biology
• Hypertension Research

Background:

• Primary hypertension in children can lead to significant end-organ damage.
• Early detection of cardiovascular effects is crucial and relies on assessing vascular structure and function.
• Investigating early cardiovascular involvement in pediatric hypertension is essential for timely intervention.

Purpose of the Study:

• To determine the presence of early cardiovascular involvement in children diagnosed with primary hypertension.
• To investigate functional and morphological changes within the vascular system of these children.

Main Methods:

• A study involving 75 children with primary hypertension and 35 healthy controls, matched for age and gender.
• Assessment of carotid intima-media thickness (cIMT), carotid-femoral pulse wave velocity (PWVcf), Pulse Wave Augmentation Index (AIx), and Left Ventricular Mass Index (LVMi).
• Patients were categorized based on their blood pressure stages.

Main Results:

• Children with primary hypertension exhibited significantly higher PWVcf and AIx compared to healthy controls.
• Carotid intima-media thickness (cIMT) was significantly elevated in the hypertensive group.
• Left Ventricular Mass Index (LVMi) was also found to be significantly higher in children with primary hypertension.

Conclusions:

• Vascular findings, including cIMT and PWVcf, demonstrated greater sensitivity in detecting target organ changes compared to LVMi in children with pre-hypertension.
• Early identification of vascular alterations is critical for managing pediatric hypertension and preventing long-term complications.
