Summary

Pulmonary congestion signs and cardiothoracic index are key predictors of one-year mortality in chronic heart failure patients. This finding aids in better prognosis for high-risk individuals.

Area of Science:

  • Cardiology
  • Clinical Medicine
  • Prognostics

Context:

  • Investigated 125 patients with chronic heart failure (CHF) due to ischemic heart disease or dilated cardiomyopathy.
  • All patients presented with NYHA functional class II-IV symptoms.
  • Baseline echocardiography showed ejection fraction < 40% and/or cardiothoracic index > 50%.

Purpose:

  • To identify baseline clinical, laboratory, and auxiliary indicators predicting one-year mortality in CHF patients.
  • To evaluate the prognostic significance of various patient parameters.

Summary:

  • One-year mortality was 15.2% (19 deaths) in the study cohort.
  • Pulmonary congestion and cardiothoracic index were highly significant predictors (p < 0.001).
  • Other significant indicators included sodium, urea, ergometric test duration, and body weight; echocardiographic measures and NYHA class were not significant.

Impact:

  • The study highlights pulmonary congestion and cardiothoracic index as crucial prognostic markers.
  • A new four-grade classification for pulmonary congestion improves prognostic accuracy for high-risk CHF patients.
  • Findings can refine risk stratification and management strategies for chronic heart failure.
