Abstract:
Objective Chronic heart failure ( CHF) is a disease with high morbidity, and mortality.The study was designed to explore the prognostic value of rest gated SPECT myocardial perfusion ( GSMPI) in patients with chronic heart failure. Methods This study was a prospective study, in which 142 CHF patients was included from January 1, 2011 to December 31, 2012.All patients underwent GSMPI, further, summed rest score ( SRS) , left ventricular ejection fraction ( LVEF) , end-diastolic volume ( EDV) , end-systolic volume ( ESV) and phase standard deviation ( PSD) were recorded.All the patients were followed up.Primary endpoint was the major adverse cardiac events ( MACE) .Additionally, we analyzed the independent predictive factor of MACE occurrence by using the Cox proportional hazard model. Results during the follow-up, MACE occurred in 65 cases.The median time to MACE occur-rence was 28(5-48) months.The 3-year MACE free survival rate was 64.3%.Multivariate Cox proportional hazards regression analysis showed that cardiac function grade[HR(95%CI):1.761(1.087~4.824), P=0.005], NT-proBNP[HR(95%CI):1.153(1.125~5.997), P =0.009], LVEF[HR(95%CI): 1.945(1.138 ~
6.131), P=0.019], SRS[HR(95%CI):1.517(1.108~4.278), P=0.027] and PSD[HR(95%CI):1.442(1.156~5.339), P=0.032] were all independent predictors of MACE. Conclusion GSMPI may be a prognostic factor for the patients with chronic heart failure.
