Pneumonia linked to short-term CVD risk in elderly
Analysis of data from two cohorts showed that the risk declined over the first year, but over 10 years of follow-up, patients maintained a 1.5-fold higher risk of CVD.
While the link between infection and CVD has been shown in several studies previously, the short-term association was controversial, the North American researchers said.
The analysis included data from two community-based groups, 5888 patients aged 65 years or older from the Cardiovascular Health Study and 15,792 patients aged 45–64 from the Atherosclerosis Risk in Communities study.
Each hospitalised patient was matched to two controls.
The study found that the magnitude of risk for CVD associated with pneumonia “was similar or higher compared with the risk of cardiovascular disease associated with traditional risk factors, such as smoking, diabetes, and hypertension”.
“Thus, our results suggest that pneumonia is an important risk
