Prevalence of heart failure and systolic ventricular dysfunction in older Australians: the Canberra Heart Study.

摘要: Objective: To estimate the prevalence of heart failure (HF) and left ventricular (LV) systolic dysfunction in a population-based sample older Australians. Design, setting participants: A cross-sectional survey 2000 randomly selected residents Canberra, aged 60-86 years, conducted between February 2002 June 2003. Participants were assessed by history, physical examination cardiologist, echocardiography. Main outcome measures: Age- sex-specific rates clinical HF LV (defined as ejection fraction <= 50%). Results: Of 1846 people eligible for our study, 1388 (75%) agreed to participate 1275 completed all investigations (mean age, 69.4 years; 50% men). In study sample, 72 subjects (5.6%; 95% Cl, 4.4%-7.1%) had that been previously diagnosed was confirmed assessment. further 0.6% (95% 0.3%-1.2%) undiagnosed (ie, evidence structural disease symptoms/ signs cardiac insufficiency without previous diagnosis HF). Thus, overall 6.3% 5.0%-7.7%). Clinical increased with advancing age (a 4.4-fold increase from 60-64-years group 80-86-years group; P < 0.0001). 75 (5.9%; 4.7%-7.3%) dysfunction, 44 (59%) preclinical stage disease. Conclusion: Diagnosed cases represent '' tip iceberg national burden Clinically identifiable can remain undiagnosed, majority are
