Dr. Mariell Jessup is a spokeswoman for the American Heart Association. She pointed out that new medicines have made it easier for people to control their blood pressure and cholesterol, treatment advances like angioplasty and heart bypass surgery saves the lives of many heart patients, and more people have quit smoking and started eating healthier diets.
“One could argue that we’re doing a better job of keeping people with heart disease alive,” said Jessup, who is a professor at the Hospital of the University of Pennsylvania in Philadelphia. “It’s not that people aren’t experiencing heart disease, but they’re not dying from it.”
Another expert agreed, with a twist on the thinking.
Essentially, modern medicine has gotten so good at dealing with heart disease that people are living much longer, making them more apt to eventually develop cancer, said Dr. Richard Schilsky. He is chief medical officer for the American Society of Clinical Oncology.
“We have to keep in mind that everyone’s going to die eventually from something. Any time we reduce the risk of death for any particular cause, we increase the risk you’re going to die from another cause,” Schilsky explained.
“Cancer is a disease that is fundamentally associated with aging. If you outlive all the competing causes of mortality, there’s a greater and greater likelihood that you’re going to get cancer,” Schilsky added.
That view is reflected in the states where cancer has overtaken heart disease, said Rebecca Siegel, strategic director of Surveillance Information Services for the American Cancer Society.
In those states, people seem to be healthier overall than in states where heart disease reigns supreme. Death rates for both heart disease and cancer were lower in the states where cancer was the leading cause of death, Siegel said.
“It’s not that cancer rates are high in those states at all,” Siegel said. “We all have to die from something, right?”
She added that heart disease treatment and prevention has benefited from rapid progress because it’s a more narrow field of medicine.
“Heart disease is basically one disease, whereas with cancer we’re looking at more than 100 different diseases,” she said. “You have very effective ways to prevent and treat heart disease, and we’ve had them for quite some time, whereas knowledge about the biology of cancer and how to prevent it and treat it is still in its infancy.”
In recent years — between 2011 and 2014 — heart disease and cancer deaths have both increased in roughly parallel fashion, the report noted.
Heart disease deaths increased by 3 percent between 2011 and 2014, from 596,577 to 614,348, while cancer deaths increased by 2.6 percent during the same period, from 576,691 to 591,699, the findings showed.
These increases could be related to the obesity epidemic, Siegel suggested.
“The obesity epidemic is catching up with us,” she said. “It’s overcoming our ability to prevent and treat heart disease, and there are a lot of cancers that are also associated with obesity.”
The report was published online Aug. 24 in the CDC’s NCHS Data Brief.
