AbstractBackgroundWe developed CRAX2MACE, a new tool derived from clinical and SPECT  myocardial perfusion imaging (MPI) variables, to predict 2-year probability of major adverse cardiac event (MACE) comprising death, hospitalized acute myocardial infarction or coronary revascularization.MethodsConsecutive individuals with SPECT  MPI 2001-2008 had two-year MACE determined from population-based health services data. CRAX2MACE included age, sex, diabetes, recent cardiac hospitalization, pharmacologic stress, stress total perfusion deficit (TPD), ischemic (stress-rest) TPD, left ventricular ejection fracti...

AbstractPurposeRisk stratification of patients with type 2 diabetes mellitus (T2D) remains suboptimal. We hypothesized that myocardial perfusion entropy (MPE) quantified from SPECT myocardial perfusion images may provide incremental prognostic value in T2D patients independently from myocardial ischemia.MethodsT2D patients with very high and high cardiovascular risk were prospectively included (n = 166, 65 ± 12 years). Stress perfusion defect was quantified by visual evaluation of SPECT MPI. SPECT MPI was also used for the quantification of rest and stress MPE. The primary end point ...

Authors: Hatta T, Yoda S, Hayase M, Monno K, Hori Y, Fujito H, Suzuki Y, Matsumoto N, Okumura Y Abstract Left ventricular (LV) mechanical dyssynchrony assessed with phase analysis of electrocardiogram (ECG) -gated single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is useful for predicting major cardiac events (MCEs) in patients with cardiac dysfunction. However, there is no report on its usefulness in Japanese patients with known or suspected stable coronary artery disease (CAD) with preserved LV ejection fraction (LVEF).We retrospectively investigated 3,374 consecutive patients w...

ConclusionsThe prognosis of diabetic patients for MACEs is different in men and women stratified by CAD. The worst prognosis for MACEs occurs in women with known CAD.

1448Introduction: Cardiovascular disease has found to be the leading cause of morbidity and mortality, especially in developing countries like India with a prevalence of 11%. This can be attributed to the high prevalence of risk factors like high levels of blood cholesterol and triglycerides, diabetes, hypertension, obesity etc., all of which have found to independently increase the epicardial fat volume (EFV) which is a known source of pro-inflammatory cytokines in the pericardial region augmenting the formation of atherosclerosis and eventual myocardial infarction. Myocardial perfusion imaging using SPECT.CT is commonly ...
