Predictors of positive response to cardiac resynchronization therapy
BACKGROUND Approximately 30% of patients treated with cardiac resynchronization therapy (CRT) do not achieve favourable response. The purpose of the present study was to identify echocardiographic and clinical predictors of a positive response to CRT. METHODS The study included 82 consecutive heart failure (HF) patients in New York Heart Association (NYHA) functional class III or IV with left...
متن کاملThe riddle of determining cardiac resynchronization therapy response a physiologic approach to dyssynchrony therapy.
ecently published studies have emphasized the technical ifficulty of assessing mechanical left ventricular (LV) synhrony in patients undergoing cardiac resynchronization herapy (CRT). The failure of a large, multicenter study to dentify benefit from CRT in dyssynchronous, narrow omplex heart failure (1), as well as the failure of synchrony arkers to predict success of CRT (2), has cast a cloud ...
متن کاملCardiac sympathetic reserve and response to cardiac resynchronization therapy.
BACKGROUND The objective of the present study was to investigate the effect of cardiac resynchronization therapy (CRT) on cardiac autonomic function. METHODS AND RESULTS This prospective study included 45 consecutive patients with heart failure who received CRT devices with defibrillator and 20 age-matched, healthy control subjects. At baseline and 3 months and 6 months after CRT, we assessed...
متن کاملClinical and electrocardiographic predictors of a positive response to cardiac resynchronization therapy in advanced heart failure.
AIMS Cardiac resynchronization therapy (CRT) is an effective treatment for refractory congestive heart failure (CHF). However, up to 30% of patients do not respond to CRT. The aim of this study was to identify clinical and electrocardiographic (ECG) predictors of a positive response to CRT. METHODS AND RESULTS This retrospective study included 139 consecutive patients successfully implanted w...
متن کاملNeutrophil-to-lymphocyte ratio predicts response to cardiac resynchronization therapy
BACKGROUND Neutrophil-to-lymphocyte (N/L) ratio has been associated with adverse outcomes in patients with acute coronary syndromes and increased risk for long-term mortality in patients with acute decompensated heart failure. We aimed to investigate the prognostic value of neutrophil-to-lymphocyte ratio on response to cardiac resynchronization therapy (CRT). MATERIAL AND METHODS Seventy cons...
