Patients who have been hospitalized for pneumonia are at significantly higher risk for heart disease, an Ottawa-led research team has discovered.
Pneumonia patients 65 and older are four times more likely to develop heart disease in the 30 days following infection, according to a paper published in the Journal of the American Medical Association on Tuesday.
Even after 10 years, patients who were hospitalized for pneumonia were still more likely to develop heart disease.
Lead author Dr. Vicente Corrales-Medina, an infectious diseases physician and researcher at The Ottawa Hospital, said pneumonia hospitalization is similar or even higher in magnitude as a risk for heart disease than traditional factors such as smoking, diabetes and hypertension.
The study examined the records of 3,813 patients split into two age groups — 65 and older and 45 to 64 — over a 10-year period. Corrales-Medina said previous studies have only looked at the correlation between pneumonia hospitalization and heart disease from 30 to 90 days after infection.
“This is the first time that we looked at the long-term association between pneumonia and cardiovascular disease,” Corrales-Medina said.
Corrales-Medina said the risk for heart disease 10 years after infection for a 72-year-old woman who smokes and has hypertension increases to 90 per cent from 31 per cent if she has been hospitalized for pneumonia.
The risk of heart disease for people between the age of 45 and 64 was more than twice as likely for pneumonia patients in the first two years after infection, the study found.
Other studies have found connections between pneumonia hospitalization and heart disease, but Corrales-Medina says his study was the first to look at the link in patients with no history of heart disease. The study also took into account other heart disease risk factors.
Corrales-Medina said that while the study he conducted with a team from the University of Pittsburgh confirmed the link between pneumonia hospitalization and heart disease even 10 years after infection, the reason for that has not been established.
Corrales-Medina said he now is conducting research to find out why pneumonia hospitalization may lead to heart disease.
To prevent the higher risk of cardiovascular disease, Corrales-Medina stressed the importance of preventing pneumonia through vaccination and basic hand hygiene.
