The prognostic significance of patients with heart failure complicated with pleural effusions determined by means of echocardiography is lacking. Thus we sought to determine the prognostic significance of transthoracic echocardiographic parameters at heart failure patients with pleural effusion which was evaluated incidentally during echocardiographic evaluation.
Between Jan 2002 and Dec 2012, total 151 patients with heart failure suffered from pleural effusion analysed. All patients mortality data are derived from registry center of Social Insurance Institution which officially responsible for recording all mortality data in Turkey. The diagnosis of patients’ pleural effusion status were made during echocardiographic evaluation. Kaplan-Meir survival rates were determined and subgroups were compared with log-rank test and Chi-square test.
Total 151 eligible patients were analysed. Mean age was 60±16 with 97 men (64.2%) and 54 women (35.8%). Mean duration of follow-up was 71.5±45.6 months. Fifty-one patients (33.8%) died during this follow-up period. There was not a significant difference regarding age and sex between survivors and those had died during follow-up. There were no prognostic significance of left ventricular end diastolic diameter, ejection fraction, mitral insufficiency, tricuspid insufficiency, and estimated pulmonary artery pressure (p>0.05). However dilated left atrium diameter was found to be associated with a poor prognosis (p=0.04).
Dilatation of the left atrium has a worse prognostic significance in patient with heart failure complicated with pleural effusion determined by means of echocardiography. it is no seems to have prognostic significance of other echocardiographic parameters incluiding left ventricular end diastolic diameter, ejection fraction, mitral insufficiency, tricuspid insufficiency, and estimated pulmonary artery pressure.
