Recent studies suggest that there is an increase in cardiovascular disease after pneumonia; however, there is little information on incidence of a new diagnosis of congestive heart failure (CHF) after pneumonia. The aim of this study was to assess the incidence of a new diagnosis of CHF during and after hospitalization for pneumonia in a population‐based database.
We conducted a national cohort study using U.S. Department of Veterans Affairs (VA) administrative data including patients > 65 years hospitalized with a discharge ICD‐9 diagnosis of pneumonia in fiscal years 2002‐2007 who received antibiotics within 48 hours of admission, who did not have a prior diagnosis of CHF, and who had at least 1 year of VA outpatient care. We included only the first pneumonia‐related hospitalization during the period, and follow‐up was for the 90 days after the date of admission. We used a multilevel regression model, adjusting for hospital of admission, in order to examine risk factors for a new diagnosis of CHF.
We identified 50,119 patients who were hospitalized with pneumonia during the study period, and of these, 16,989 patients (33.9%) had a prior diagnosis of CHF and were excluded from further analyses. During the index hospitalization 2442 (7.4%) had a new diagnosis of CHF, and an additional 950 (2,9%) were diagnosed with CHF after discharge but within 90 days of admission. Variables significantly associated with CHF in the multilevel model included increasing age, ICU admission, prior history of chronic kidney injury, diabetes, chronic pulmonary disease, myocardial infarction, and cerebrovascular disease.
A clinically important number of patients have new CHF posthospitalization for pneumonia. Additional research is needed to determine if use of cardioprotective medications will improve outcomes for patients hospitalized with pneumonia.
