The study, published Monday in the Canadian Medical Association Journal, was conducted by a team of eight doctors and other researchers across the province. “One of the things we began to realize in the early months of the pandemic was that the number of people with acute strokes seemed to be declining,” said lead author Dr. Aravind Ganesh, a neurologist at the University of Calgary, in an interview. Several countries, he said, were beginning to see a trend of fewer people seeking emergency medical care for various medical issues during the pandemic. “The question people started asking was whether the public health restrictions we had implemented as a result of the pandemic could have some unintended consequences by preventing people from going to the hospital for emergencies such as stroke and heart disease,” Ganesh said.

“Along with that, we also found that the use of stroke treatments decreased by about the same amount.” The researchers also found that the number of patients with symptoms of stroke did not return to pre-pandemic levels after the first wave in the spring of 2020. “Especially during the second and third waves of our study, when COVID-19 cases increased, we expected to see an increase in stroke presentation instead of a decrease,” the study said. Ganesh said he and other researchers were able to look at what happened to these patients by studying how many people died from strokes. “We found that these out-of-hospital deaths resulted in an increase of four of the five pandemic periods,” he said. “We ended up finding some of those strokes that were missing this way.” The story goes on under the ad Similar results were found in hospitals. “During the second wave of the pandemic and the third wave of the pandemic, more people died in hospital with strokes,” he said.

Ganesh said researchers did not know for sure, but believed that people were trying to avoid hospitals. “We suspect that it was an avoidance of hospitals due to the outpatient deaths we found.” He said the results of the investigation were not all bad. “We actually ended up closing the gap later in the pandemic,” Ganesh said. He said public health officials and doctors also worked to remind people to go to the hospital for emergencies. “What we understand is that we really need to think critically about the kind of public health messages we send during a pandemic.” © 2022 The Canadian Press
