Predictive value of myocardial tomoscintigraphy in asymptomatic diabetic patients after percutaneous coronary intervention

Objective: This study was designed to assess the prognostic value of myocardial tomoscintigraphy perfusion imaging after percutaneous coronary intervention (PCI) in asymptomatic diabetic patients. Methods: One hundred and fourteen diabetic patients were followed up during 27±16 (mean±SD) months afte...

Description
Summary:Objective: This study was designed to assess the prognostic value of myocardial tomoscintigraphy perfusion imaging after percutaneous coronary intervention (PCI) in asymptomatic diabetic patients. Methods: One hundred and fourteen diabetic patients were followed up during 27±16 (mean±SD) months after the myocardial tomoscintigraphy. PCI-related events were studied after myocardial tomoscintigraphy stress testing and included major cardiac events (MACE) (cardiovascular death, myocardial infarction) and revascularization (bypass surgery or new PCI). Stress myocardial tomoscintigraphy imaging was performed 5±5 months after PCI and ischemia was considered as present if at least 2 contiguous segments were showing reversible defects. Results: Persistent silent ischemia was found in 49/114 (43%) patients. No difference was observed between the two groups for MACE: four among the 65 (6%) non ischemic patients versus 2 among the 49 (4%) ischemic patients (NS). In contrast, 15 (31%) among the ischemic patients and 4 (6%) among the non ischemic patients underwent iterative revascularization ( p
