Abstract

Objectives: The purpose of this study was to evaluate the predictive value of perfusion/function parameters measured by gated myocardial perfusion single-photon emission computed tomography (SPECT) in combination with clinical variables in patients with known or suspected coronary artery disease to predict refractory heart failure (HF). Background: The increasing number of HF patients requires the establishment of a prophylactic strategy that can identify patients at high risk of HF due to coronary artery disease. Methods: We analyzed clinical and stress/rest-gated SPECT data from the multicenter, prospective, and observational J-ACCESS (Japanese Assessment of Cardiac Events and Survival Study by Quantitative Gated SPECT) database of 3,835 known or suspected coronary artery disease patients in which new-onset congestive HF symptoms requiring aggressive medical treatment were observed in 71 patients for 3 years. Results: The multivariable Cox hazard model revealed that chronic renal dysfunction (hazard ratio (HR): 6.227 [95% confidence interval (CI): 2.920 to 13.279]), the end-systolic volume index (ESVI) (HR: 1.019 [95% CI: 1.011 to 1.029]), and moderate to high stress summed score (SSS) (HR: 3.012 [95% CI: 1.757 to 5.181]) independently (p <0.0001) predicted HF. In addition to the close (p <0.0001) correlation of ESVI and SSS with HF incidence, the combined tertiles of SSS and ESVI revealed high-risk patients with a maximally 17.3 times greater risk (5.2%/3 years) compared with the minimal risk (0.3%/3 years) at a normal to low SSS and lower ESVI. Chronic renal dysfunction combined with ESVI and SSS categories had the greatest (p <0.005 to 0.001) incremental prognostic value with a global chi-square value (125.0) over single or other combined risks. Conclusions: Chronic renal dysfunction, greater stress-induced perfusion abnormality, and higher ESVI provide independent and additive information for predicting the risk of refractory HF in known or suspected coronary patients, indicating the efficacy of perfusion/function parameters measured by stress-gated perfusion SPECT for identifying patients at greater risk of future refractory HF.
