Women with breast cancer have an increased risk of atrial fibrillation

Women with breast cancer may have a higher incidence of atrial fibrillation (AF) within three years after the diagnosis of cancer compared with other women of the same age, according to a retrospective study conducted in Denmark and published in the journal HeartRhythm.

According to the World Cancer Research Foundation, breast cancer is most common among women all over the world and the second most common. In fact, worldwide in 2018, more than two million new cases were reported. Researchers suggest that patients with breast cancer may develop AF because it causes inflammation, a known risk factor. for atrial fibrillation.

Current treatments allow approximately 80 percent of breast cancer patients to survive for a long time. However, long-term complications from both cancer and treatment can threaten healthy survival. In particular, the survivors experienced an increase in the frequency of cardiovascular diseases, especially heart failure and ischemic heart disease.

Using national registries in Denmark, researchers analyzed the long-term incidence of atrial fibrillation among these patients compared to the general population. They identified women diagnosed with breast cancer between 1998 and 2015, and then compared 74 155 patients with breast cancer, depending on age and gender, with 222,465 random people.

Researchers have found that patients with breast cancer have an increased risk of AF, and this risk depends on the age and time since the diagnosis was made. People under the age of sixty had a double risk in the first six months after diagnosis, and 80 percent higher risk from six months to three years after diagnosis. Those over sixty had a risk similar to that of the population during the first six months, but they had an increase in risk from 14 percent from six months to three years later.
