Children who undergo treatment for cancer may be at greater risk of developing heart disease later in childhood, as well as in adulthood, according to a new study presented to the American Heart Association. Researchers recommended that pediatricians monitor heart health carefully in their patients who have undergone cancer treatments. More from The New York Times:
Scientists have known for some time that survivors of childhood cancer are several times more likely to develop cardiovascular disease as adults, a result of the toll that lifesaving radiation and chemotherapy treatments can have on the heart. But the new study, presented at an American Heart Association conference over the weekend, is among the first to show that the risk is elevated while the survivors are still children.
The research looked at 319 boys and girls under the age of 18 who underwent chemotherapy treatments for leukemia or cancerous tumors. At the time of the study, the participants were a minimum of five years past the time of their diagnosis.
When the children were compared with 208 siblings of similar ages, the researchers found a nearly 10 percent decrease in arterial health and other signs of premature heart disease.

A growing number of children are being hospitalized for hypertension and high blood pressure, a new study published in the American Heart Association’s journal, Hypertension, has found. The study showed a sharp increase from 12,661 hospitalizations in 1997 to 24,602 in 2006. CNN.com reports that the increase in childhood obesity is a likely cause of the trend:
The researchers reviewed hospital discharge data for the study. They included all children aged 2 to 18 who were treated for hypertension during hospitalizations, regardless of their primary diagnosis or the main reason why they were hospitalized.
Those most likely to have high blood pressure were older than 9, male and African-American, according to the study. Some had end-stage renal (kidney) disease.
The study found children with hypertension had an average length of stay of eight days- double that of non-hypertensive kids.
Childhood obesity may play a role in the sharp increase in hospitalizations.
American Heart Association spokesman Dr. Ernesto Schiffrin from the Department of Medicine at McGill University, Montreal, Quebec said obesity seems to be an even stronger risk factor for high blood pressure in children than it is in adults.
“Increasingly, these are children with essential hypertension- this is consequence of the epidemic of obesity and diabetes that is found increasingly in teenagers and younger children,” he said.
“If we are going to prevent adult hypertension, we have to start at this early age by avoiding obesity, cutting back on salt and exercising- otherwise this will increase further the prevalence of adult hypertension and the huge costs that will occur accordingly.”
