[PH score--a new scoring system for pulmonary hypertension with chronic lung disease]
1Kanagawa Children's Medical Center.
Insights
This study introduces a new echocardiography scoring system to evaluate pulmonary hypertension in infants with chronic lung disease. This method aids in managing pediatric patients requiring home oxygen therapy.
Area of Science:
- Pediatric Cardiology
- Neonatology
- Pulmonary Medicine
Background:
- Pulmonary hypertension (PH) is a severe complication in infants with chronic lung disease.
- Current outpatient evaluation methods for PH in this population are lacking.
- Accurate assessment is crucial for effective management and improving outcomes.
Purpose of the Study:
- To develop and validate a non-invasive echocardiography-based scoring system for diagnosing and grading PH in infants.
- To provide a reliable tool for outpatient management of pediatric PH.
- To correlate the scoring system with estimated pulmonary arterial pressure.
Main Methods:
- A scoring system was developed using seven echocardiographic parameters: RSTI, AT/ET, LV (S/L), RVaw (d), RVaw (s), P/A, and T/M.
- The total PH score was correlated with pulmonary arterial pressure estimated via the maximum velocity of tricuspid regurgitation.
- Infants were categorized into no PH (<2 points), mild PH (2-4 points), moderate PH (5-8 points), and severe PH (>8 points).
Main Results:
- The developed scoring system demonstrated a correlation with estimated pulmonary arterial pressure.
- The system effectively categorized infants into different severity levels of PH.
- The scoring system proved useful for managing infants on home oxygen therapy.
Conclusions:
- The novel echocardiography scoring system offers a valuable tool for assessing pulmonary hypertension in infants with chronic lung disease.
- This non-invasive method facilitates outpatient management and monitoring of pediatric PH.
- The system aids in stratifying disease severity and guiding therapeutic decisions for infants requiring home oxygen therapy.
Abstract:
Pulmonary hypertension is the most serious complication with the infants of chronic lung disease and pulmonary hypertension. There were no evaluating methods available for outpatients. We've made the scoring system from seven parameters of echocardiography which consist of RSTI, AT/ET, LV (S/L), RVaw (d), RVaw (s), P/A, T/M. The points of total PH score are correlated with estimated pulmonary arterial pressure from the maximum velocity of tricuspid regurgitation. The infants of points less than 2 are considered no PH, points 2 to 4 are mild PH, points 5 to 8 are moderate PH, points more than 8 are severe hypertension. The system has revealed useful for management of patients with home oxygen therapy.
