Background: The management of patients with unprotected left main (LM) coronary artery disease remains challenging, with recent data casting a shadow of doubt on the safety of percutaneous coronary intervention. We aimed at describing the features of patients undergoing myocardial perfusion imaging (MPI) subsequently found to have LM disease.

Methods: We queried our institutional database for subjects without prior revascularization or myocardial infarction (MI), who had undergone MPI followed by invasive coronary angiography within 6 months, comparing those with evidence of angiographically significant LM disease (i.

Background: Whether estimates of myocardial perfusion reserve (MPR) stemming from new-generation cadmium-zinc-telluride (CZT) cameras are accurate remains unclear.

Methods: We queried our institutional database for patients undergoing MPR with CZT cameras. The primary goal was appraising the incremental diagnostic yield of MPR on top or at odds of maximal ischemia score (MIS).

Aims: Prior studies using stress myocardial perfusion imaging (MPI), which examined the association between obstructive epicardial coronary disease and presence of myocardial ischemia did not provide a detailed assessment on a regional level. We examined this relationship in a large population of patients in whom the coronary anatomy was defined by invasive coronary angiography.

Methods: We retrospectively extracted details on individuals undergoing MPI with single photon emission computed tomography (SPECT) who had coronary angiography within 12 months.

Background: Myocardial perfusion imaging (MPI) has an established role in the work-up of coronary artery disease (CAD), but its comparative accuracy is debated in elderly patients. We examined a large administrative database to appraise the performance of MPI in octogenarians.

Methods: Our institutional database was queried for patients undergoing MPI without recent coronary revascularization or myocardial infarction (MI).

The definition, presentation, and management of myocardial infarction (MI) have changed substantially in the last decade. Whether these changes have impacted on the presence, severity, and localization of necrosis at myocardial perfusion imaging (MPI) has not been appraised to date. Subjects undergoing MPI and reporting a history of clinical MI were shortlisted.

Aims: The impact of coronary revascularization on outcomes and ischemic burden among patients with objective proof of ischemia is not yet established. We appraised the impact of revascularization on outcomes and residual ischemia in patients with objective evidence of ischemia at myocardial perfusion scintigraphy (MPS).

Methods: We queried our database for stable patients with myocardial ischemia at MPS, excluding those with prior myocardial infarction, systolic dysfunction, or cardiomyopathy.

Background: Myocardial necrosis after myocardial infarction (MI) is common; extent and severity are however variable. The pattern is recognized by myocardial perfusion imaging (MPI) as fixed perfusion defects (FPD). The fate of such FPD is not well appraised.

Background: Randomized trials have challenged the role of revascularization in stable coronary artery disease. We aimed to appraise the impact of revascularization on ischemia in patients undergoing serial myocardial perfusion scintigraphy (MPS).

Methods: We queried our institutional database for stable subjects undergoing serial MPS and appraised the impact of revascularization on changes in ischemia.

Background: Hypoglycemic agents differ in mechanism, efficacy, and profile. However, there is uncertainty on their impact on myocardial perfusion. We thus aimed to investigate whether individuals with type 2 diabetes mellitus treated with different drug classes exhibit different perfusion patterns at myocardial perfusion scintigraphy (MPS).

Background: Myocardial perfusion scintigraphy (MPS) has an established diagnostic and prognostic role in patients with or at risk for coronary artery disease, with ischemia severity and extent having already been identified as key predictors. Whether this is affected by the location of myocardial ischemia is uncertain. We aimed at comparing the prognostic outlook of patients undergoing MPS according to the site of ischemia.

Background: The burden of cardiovascular disease is increasing, yet it remains difficult to focus preventive strategies on populations at highest absolute and relative risks. We compared absolute and relative cardiovascular event counts, plus time to first event, among patients undergoing myocardial perfusion scintigraphy (MPS).

Methods And Results: Our database was queried to identify subjects without myocardial necrosis or recent revascularization, focusing on cardiac death (CD) or myocardial infarction (MI).

Background: Myocardial perfusion scintigraphy (MPS) represents a key prognostic tool, but its predictive yield is far from perfect. We developed a novel clinically relevant segmentation method and a corresponding maximal ischemia score (MIS) in order to risk-stratify patients undergoing MPS.

Methods: Patients referred for MPS were identified, excluding those with evidence of myocardial necrosis or prior revascularization.
