Abstract

Only few data are available regarding the prognostic impact of myocardial perfusion scintigraphy with (99m)Tc-sestamibi (MPS) regarding emerging cardiac events in elderly patientsTo evaluate the prognostic value of MPS regarding emerging cardiac events in patients aged ?70 years with known or suspected coronary artery disease (CAD).One hundred and thirty-three patients (74.6 ? 3.7 years) who underwent exercise or pharmacological stress/rest MPS were included in this analysis. Semi-quantitative visual interpretation of MPS images was performed and Summed-Stress- (SSS), Summed-Difference- (SDS), and Summed-Rest Scores (SRS) were calculated. Multivariate logistic regression analyses were calculated for evaluation of the independent prognostic impact of MPS results and several cardiac-related patient characteristics with regard to emerging cardiac events. Kaplan-Meier survival- and log rank analyses were calculated for assessment of cardiac event-free survival.Pathological SSS (OR: 3.3), angina (OR: 2.7) and ischemic ECG (OR: 3.0) were independently associated with cardiac events. Patients with pathological SSS (p=0.005) and ischemic ECG (p=0.012) had a significantly lower incidence of cardiac event-free survival.Pathological MPS is independently associated with emerging cardiac events predicting a significantly lower incidence of cardiac event-free survival in patients aged ?70 years.
