Abstract

Background— Information is limited regarding the rates of progression to congestive heart failure (CHF) and death in individuals with asymptomatic left ventricular systolic dysfunction (ALVD). We sought to characterize the natural history of ALVD, by studying unselected individuals with this condition in the community. Methods and Results— We studied 4257 participants (1860 men) from the Framingham Study who underwent routine echocardiography. The prevalence of ALVD (visually estimated ejection fraction [EF]≤50% without a history of CHF) was 6.0% in men and 0.8% in women. During up to 12 years of follow-up, rates of CHF among subjects with normal left ventricular systolic function (EF >50%, n=4128) and ALVD (n=129) were 0.7 and 5.8 per 100 person-years, respectively. After adjustment for cardiovascular disease risk factors, ALVD was associated with a hazards ratio (HR) for CHF of 4.7 (95% CI 2.7 to 8.1), compared with individuals without ALVD. An elevated risk of CHF after ALVD was observed even in individuals without prior myocardial infarction or valvular disease, with an adjusted HR of 6.5 (CI 3.1 to 13.5). Mild ALVD (EF 40% to 50%, n=78) and moderate-to-severe ALVD (EF <40%, n=51) were associated with adjusted HRs for CHF of 3.3 (CI 1.7 to 6.6) and 7.8 (CI 3.9 to 15.6), respectively. ALVD was also associated with an increased mortality risk (adjusted HR 1.6, CI 1.1 to 2.4). The median survival of ALVD subjects was 7.1 years. Conclusion— Individuals with ALVD in the community are at high risk of CHF and death, even when only mild impairment of EF is present. Additional studies are needed to define optimal therapy for mild ALVD.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • There are no strategies to identify individuals at risk of developing structural heart diseases, despite evidence-based interventions that can alter the course of patients.

    “Moreover, there are no strategies to identify individuals at risk of developing SHDs, despite the presence of evidence-based interventions that can alter the course of patients.6-8”
  • Recent guidelines emphasize detection of asymptomatic ventricular dysfunction (stage B heart failure) to understand and prevent overt heart failure.

    “Recent guidelines have a notable emphasis on the detection of asymptomatic ventricular dysfunction (“stage B heart failure”) as part of efforts to understand and prevent overt heart failure.61”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
