[Immediate and long-term effects of posthypoxic myocardial ischemia in newborns]
Insights
Infant heart adaptation to hypoxia can lead to cardiovascular issues, with 37% developing posthypoxic cardiomyopathy. Severe cases may progress to dilated cardiomyopathy, impacting long-term health.
Area of Science:
- Cardiology
- Neonatology
- Pediatrics
Context:
- Hypoxia during the perinatal period affects neonatal cardiovascular adaptation.
- Early neonatal period is critical for heart development and recovery.
- 294 infants with perinatal hypoxia history were studied.
Purpose:
- To investigate heart adaptation to hypoxia in neonates.
- To analyze the developmental trajectory of infants experiencing perinatal hypoxia.
- To establish the strain index as a prognostic criterion for cardiovascular disorders.
Summary:
- Cardiovascular disorders in neonates post-hypoxia correlate with hypoxia duration and severity.
- Strain index effectively characterizes myocardial activity and predicts outcomes.
- 37% of infants developed posthypoxic cardiomyopathy, with 16.7% progressing to dilated cardiomyopathy.
Impact:
- Identifies risk factors and outcomes of neonatal hypoxia-induced heart conditions.
- Highlights the potential for long-term consequences like dilated cardiomyopathy and heart failure.
- Emphasizes the importance of assessing hypoxic myocardial injury and timely adjuvant therapy for improved prognosis.
Abstract:
The aim of the research was to study heart adaptation to hypoxia in infants in the early neonatal period and the dynamics of their development catamnesis of 294 infants who underwent hypoxia in the perinatal period was examined. Strain index is used as a prognostic criterion of cardiovascular disorders, which characterizes the activity index of independent contour and coefficient of myoglobin. Intensity of cardiovascular disorders in infants in the early neonatal period depended on the length and severity of hypoxia. Follow-up data revealed various outcomes posthypoxic myocardial ischemia. In most cases, there is a benign outcome in recovery, but in 37% of cases developed posthypoxic cardiomyopathy. Long-term consequences of posthypoxic myocardial more pronounced in severe cardiomyopathy in 16.7% posthypoxic cardiomyopathy transformed into dilated cardiomyopathy, accompanied by life-threatening arrhythmias and heart failure.The immediate forecast and remote consequence of posthypoxic myocardial ischemia depends on the degree of hypoxic myocardial injury, timely adjuvant therapy.
