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). We compared baseline, procedural, diagnostic, and prognostic features in patients aged

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. This study addressed this important issue in a large number of patients undergoing serial MPI in relation to type of intervening therapy.

Objective The aim of this study is to evaluate the long-Term risk of cardiac death and sudden cardiac death (SCD) and/or sustained ventricular arrhythmias (SVAs) in patients with coronary chronic total occlusions (CTO) revascularised versus those with CTO not revascularised by percutaneous coronary intervention (PCI). Methods From a cohort of 1357 CTO-PCI patients, 1162 patients who underwent CTO PCI attempt were included in this long-Term analysis: 837 patients were revascularised by PCI (CTO-R group) and 325 were not revascularised (CTO-NR group).

Large multicenter studies and meta-analysis have documented the diagnostic accuracy and the prognostic implications of stress echocardiography, cardiac magnetic resonance and, mainly, nuclear stress tests. However, none of them provides a comprehensive anatomical and functional evaluation within the same study as stress CT perfusion.

Introduction: Several studies have been performed to assess the efficacy of postmortem computed tomography angiography (PMCTA) in solving cases of sudden cardiac death, even in comparison with the traditional autopsy. However, the results were often inconsistent and inconclusive. Therefore, a global discussion on the subject through a systematic review of the literature and a meta-analysis is necessary. Methods: A systematic search of PubMed was performed up to April 23, 2018.

Background: The impact of seasonal changes on the incidence of acute myocardial infarction has been incompletely appraised, especially in the modern era of primary percutaneous coronary intervention (PPCI). We aimed to appraise the overall and season-specific impact of climate changes on the daily rate of PCCI. Methods: Details on PPCI and climate changes were retrospectively collected in three high-volume Italian institutions with different geographical features.

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 subsequently found to have LM disease.

The concomitant presence of myocardial necrosis with myocardial ischemia, stunning and hibernation may complicate appraisal of left ventricular (LV) function and patient management. Several imaging modalities have been proposed for the accurate assessment of myocardial necrosis, viability, stunning and hibernation, with mixed results. We aimed to review the evidence base on myocardial necrosis, stunning and hibernation by conducting an umbrella review (i.e. overview of systematic reviews).

Aims: Incidence, associated risk factors and impact on mortality of infections after bypass surgery (CABG) and stenting (PCI) for multivessel coronary disease (MVD) have never been reported in a large randomised trial. The aim of the present study was to evaluate, in patients with MVD, the prevalence of major infections after PCI and CABG and to assess their impact on mortality. Methods and results: The SYNTAX trial randomised 1,800 MVD patients to either CABG or PCI. Patients were followed up to five years.
