Insights
Environmental exposures before and after birth, including drugs and nutritional deficiencies, can cause pediatric and adult cardiovascular anomalies. These exposures impact heart structure, function, and long-term cardiovascular health.
Area of Science:
- Cardiovascular Science
- Developmental Biology
- Environmental Health
Background:
- Prenatal and postnatal exposures to various agents can induce cardiovascular anomalies.
- Nutritional deficiencies during the perinatal period are linked to heart defects.
- Different developmental stages present unique risks for cardiovascular health.
Purpose of the Study:
- To review the impact of environmental exposures on cardiovascular development and disease.
- To highlight critical windows of vulnerability from embryonic to adolescent periods.
- To discuss the long-term cardiovascular consequences of early-life exposures.
Main Methods:
- Literature review of studies on environmental exposures and cardiovascular anomalies.
- Analysis of risks associated with different developmental periods (embryonic, fetal, neonatal, childhood, adolescence).
- Inclusion of disease models to illustrate potential impacts where direct evidence is limited.
Main Results:
- Congenital malformations are most vulnerable during the embryonic period.
- Fetal exposures can lead to lifelong coronary heart disease risks.
- Childhood exposures (chemotherapy, radiation, drugs) increase risks for ventricular dysfunction and other cardiovascular issues.
Conclusions:
- Early-life environmental exposures significantly influence cardiovascular development and health outcomes.
- Understanding critical exposure windows is crucial for preventing cardiovascular anomalies.
- Long-term cardiovascular risks are associated with exposures throughout prenatal and postnatal development.
Abstract:
Exposures to drugs, chemical and biological agents, therapeutic radiation, and other factors before and after birth can lead to pediatric or adult cardiovascular anomalies. Furthermore, nutritional deficiencies in the perinatal period can cause cardiovascular anomalies. These anomalies may affect heart structure, the conduction system, the myocardium, blood pressure, or cholesterol metabolism. Developmental periods before and after birth are associated with different types of risks. The embryonic period is the critical window of vulnerability for congenital malformations. The fetal period seems to have lifelong effects on coronary heart disease and its precursors. During the weeks immediately after birth, susceptibility to myocardial damage seems to be high. Exposure to cancer chemotherapy or radiotherapy in childhood raises the risk of long-term progressive left ventricular dysfunction and other cardiovascular problems. In childhood and adolescence, use of recreational drugs such as cocaine and tobacco poses cardiovascular dangers as well. Where evidence about environmental exposures is limited, we have included models of disease and other exposures that are suggestive of the potential impact of environmental exposures.

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
