Insights

Central systolic blood pressure (cSBP) significantly increases over time in children with congenital heart disease (CHD). This longitudinal rise in cSBP warrants further investigation and focused monitoring in specific patient groups.

Area of Science:

  • Pediatric Cardiology
  • Cardiovascular Physiology
  • Longitudinal Health Studies

Background:

  • Central systolic blood pressure (cSBP) is elevated in children with congenital heart disease (CHD).
  • The developmental trajectory of cSBP over time in pediatric CHD populations has not been previously studied.

Purpose of the Study:

  • To longitudinally assess the natural course of cSBP in children and adolescents diagnosed with CHD.
  • To identify factors influencing the progression of cSBP in this cohort.

Main Methods:

  • A prospective longitudinal study involving 306 children and adolescents with CHD.
  • Noninvasive oscillometric measurement of cSBP over a mean follow-up of 30.1 months.
  • Analysis using a linear mixed-effects model to determine cSBP trends.

Main Results:

  • cSBP demonstrated a significant annual increase of 1.22 mmHg in children with CHD.
  • This increase remained significant after adjusting for sex, BMI, medication, disease severity, and CHD type.
  • Higher cSBP increases were observed in patients with transposition of the great arteries (TGA) post-arterial switch, obese children, and boys.

Conclusions:

  • This study confirms a significant longitudinal increase in cSBP among children with CHD.
  • Further research is needed to determine if these cSBP trajectories are abnormal.
  • Monitoring vascular function, particularly in TGA patients and obese children with CHD, is recommended.

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Blood Pressure01:24

Blood Pressure

The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Development of the Heart01:27

Development of the Heart

The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...
