Patients diagnosed with any one of these common infections were three times more likely to die than those without prior infection after developing heart disease, and almost twice as likely to die if they had a stroke.
"Our figures suggest that those who are admitted to hospital with a respiratory or urinary tract infection are 40 per cent more likely to suffer a subsequent heart attack, and 2.5 times more likely to have a stroke, than patients who have had no such infection - and are considerably less likely to survive from these conditions," Rahul Potluri, researcher at Britain's Aston University, said in a statement.
The effects of the common infections were of similar magnitude among the people suffering from diabetes, hypertension, and cholesterol, researchers said.
"It is notable that infection appears to confer as much, if not more, of a risk for future heart disease and stroke as very well established risk factors such as high blood pressure and diabetes," Potluri added.
Factors such as age, gender, ethnicity, obesity and tobacco use, as well as medical conditions including excess cholesterol, high blood pressure, diabetes and kidney disease, heart failure and atrial fibrillation were also taken into account.
