People who develop pneumonia that is severe enough to result in hospitalization face greater risk of stroke.
The researchers examined data from two studies, one of which followed nearly 6,000 adults over 65, while the other followed nearly 16,000 adults aged 45 to 64.
They found that patients hospitalized for pneumonia were more likely to have a stroke, while the odds of having a heart attack and heart failure experience were also higher.
highest risk in the group of 65 and was in the first year after infection. During the first 30 days, which was four times greater than that of people of similar ages who had not been hospitalized with pneumonia. The risk remained high for a decade.
The risk also increased in the younger cohort, though not as high as among the older age group and seemed to stabilize after two years.
The lead author, Dr. Vicente Corrales-Medina Ottawa Hospital, said the study confirms observations made by doctors in recent years.
He told the Canadian newspaper The Globe and Mail that no research has previously been conducted to determine whether the relationship between pneumonia and these conditions is a coincidence or a genuine connection.
There is no way to know whether people with pneumonia that is not severe enough to require hospitalization are also at higher risk of having a cardiovascular event, he added.
Experts recommend that patients and doctors make every effort to reduce the risk of pneumonia, such as vaccination.
Steps can also be taken to control the other factors that lead to cardiovascular disease, such as pressure and cholesterol levels in the blood.
Currently the reason is unknown pneumonia is linked to an increased risk of developing cardiovascular disease, although it is believed that other infections have a similar effect.
