简要总结
This observational feasibility study aims to assess (i) how practical and acceptable repeated KCCQ assessments are; (ii) the connection between changes over time in KCCQ scores and signs of congestion; and (iii) clinical outcomes, including worsening heart failure events or cardiovascular death (CVD), and the time between 5- and 10-point KCCQ changes and clinical events.
详细描述
The course of heart failure (HF) is characterized by episodes of worsening HF (WHF). These episodes increase the risk of hospitalization and death. Currently, reliable instruments for early identification of WHF are underdeveloped. The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a disease-specific, self-administered instrument designed to assess patient status. KCCQ allows detection of changes in clinical status in HF patients within a 14-day recall period and has the potential for early detection of WHF.
The study is an investigator-initiated, prospective, observational feasibility study aims to assess the (i) feasibility and acceptability of serial KCCQ assessment; (ii) the relationship between temporal changes in KCCQ scores and markers of congestion, as well as (iii) clinical outcome, a composite of worsening heart failure events or cardiovascular death (CVD), and the time from 5- and 10-point KCCQ changes to clinical events.
The study population will include 120 patients aged 18 years and above who meet the criteria. Eligible patients will undergo serial KCCQ assessments every 2 weeks for 12 months. Transthoracic echocardiography (TTE), lung ultrasound (LUS), 6-minute walk test (6MWT), and blood sampling will be performed at baseline, 3, 6, and 12 months. Outcomes will be collected at 6 and 12 months.
