چکیده

Prevalence and prognostic value of diastolic and systolic dyssynchrony in patients with coronary artery disease (cad) + heart failure (hf) or cad alone are not well understood. we included patients with gated single-photon emission computed tomography (gspect) myocardial perfusion imaging (mpi) between 2003 and 2009. patients had at least one major epicardial obstruction ≥ 50%. we assessed the association between dyssynchrony and outcomes, including all-cause and cardiovascular death. of the 1294 patients, hf was present in 25%. median follow-up was 6.7 years (iqr 4.9-9.3) years with 537 recorded deaths. patients with cad + hf had a higher incidence of dyssynchrony than patients with cad alone (diastolic bw 28.8% for the hf + cad vs 14.7% for the cad alone). patients with cad + hf had a lower survival than cad alone at 10 years (33%; 95% ci 27-40 vs 59; 95% ci 55-62, p < 0.0001). with one exception, hf was found to have no statistically significant interaction with dyssynchrony measures in unadjusted and adjusted survival models. patients with cad + hf have a high prevalence of mechanical dyssynchrony as measured by gspect mpi, and a higher mortality than cad alone. however, clinical outcomes associated with mechanical dyssynchrony did not differ in patients with and without hf.
