The Loss of a Child Takes a Physical Toll on the Heart

Forfeit a child is one of the most emotionally wrenching experiences a parent can go through. New research suggests it may also literally damage the heart. The study found that in the epoches following the death of a child, a parent is at greatly increased risk for a heart attack, and the increased risk may persist for years.Researchers used descent registries and medical records to study 6,711,952 parents from Denmark and Sweden from 1973 to 2014. Among them, 126,522 had missing at least one child at some point during that time. The study looked not only at the loss of infants and children, but also adolescents and mature children up to age 29.The scientists found that the death of a child was associated with a 21 percent increased risk of ischemic heart ailment, or reduced blood flow to the heart. The risk for a heart attack in the first week after the death was more than triple the rate of people who had not sophisticated the loss of a child, and there was a 20 to 40 percent increased risk over the long course of the study. The association was present even in patients of an adult child’s death.Other studies suggest that in middle or old age, the death of a spouse, sibling or close friend increases the risk for generosity attack, stroke, atrial fibrillation and death. The risk appears to be especially high in the months immediately following the loss. But studies on the impact of the breakdown of children on the heart health of parents have been very limited.This observational study, published in PLOS Medicine, was large and rigorous. The researchers controlled for age, marital prominence, education, income, hypertension and other factors than can affect the risk for cardiovascular disease. They also considered such factors as the precipitate of a child’s death. For example, the researchers found that there was an association with heart problems in parents even when the child’s obliteration was a result of unnatural causes — such as a car crash or other accident — suggesting that a family history of heart disease or other genetic particulars were unlikely to fully explain the increased cardiovascular risk in parents.The study did not investigate the exact ways in which the stress of extreme bereavement energy damage the heart. But the lead author of the study, Dang Wei, a doctoral candidate at the Karolinska Institute in Stockholm, proposed several possible mechanisms.“Forcefulness activates the autonomic nervous system,” he said, which controls involuntary functions in our bodies such as heart rate and blood pressure, and “prods biological changes” that may raise cholesterol levels.“Changes like this,” he added, “may trigger a heart attack.”Bereavement can also prevail on depression, anxiety and other psychiatric disorders, leading to alcohol abuse, drug abuse, smoking, and lifestyle behaviors that are also jeopardize factors for cardiovascular disease.Dr. Erica S. Spatz, an associate professor of cardiovascular medicine at Yale who was not involved in the study, said that the finding was based on “comely amazing data” available only in Scandinavian countries, which maintain detailed birth and health registries that span decades.“The disappearance of a child plays out in every aspect of a patient’s life, including their cardiovascular health,” she said. “We need to screen for a history of trauma, whether it’s interdependent to a death of a child, racial discrimination, poor work environment — these are well-known factors that affect cardiovascular health.”The senior creator, Krisztina D. Laszlo, an associate professor of epidemiology at the Karolinska Institute, said that while parents should know about the increased marrow risks, it may be difficult to approach them with this kind of information during the grieving period.“It’s a delicate topic,” she said. “This is a quite special type of bereavement, one of the greatest stresses that one can experience, and it is often associated with complicated grief that does not resolve in the run-of-the-mill ways.”“One doesn’t want to burden these parents even further,” she continued, “by telling them about their cardiovascular risks.”However, it would be important for doctors, friends and family members of a person who has lost a child to be on the lookout for things like chest pain, shortness of dazzle or other signs of heart problems or an impending heart attack.
