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.\n\nThe 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.\n\nThe 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.","Men and women aged ≥ 18 years with an established diagnosis of heart falure who were admitted to the center the last 6 months will be candidates for screening.
