Rationale and design of the multicentric randomized EVAOLD trial: Evaluation of a strategy guided by imaging versus routine invasive strategy in elderly patients with ischemia.

Background: The management of myocardial infarction without ST segment elevation (NSTEMI) in elderly patients remains challenging, in particular the benefit/risk balance of routine revascularization remains uncertain.

Study Design: EVAOLD is s a multicenter, prospective, open-label trial with 2 parallel arms in NSTEMI patients ≥80 years of age. The aim of the trial is to test whether a strategy of selective invasive management guided by ischemia stress imaging (IMG group) will be noninferior in preventing Major Adverse Cardiac and Cerebrovascular Events (MACCE, ie all-cause death, nonfatal myocardial infarction, nonfatal stroke) rates at 1 year compared with a routine invasive strategy (INV Group).

Regional CZT myocardial perfusion reserve for the detection of territories with simultaneously impaired CFR and IMR in patients without obstructive coronary artery disease: a pilot study.

Objectives: To assess the diagnostic performances of CZT myocardial perfusion reserve (MPR) for the detection of territories with simultaneous impaired coronary flow reserve (CFR) and index of microcirculatory resistance (IMR) in patients without obstructive coronary artery disease.

Methods: Patients were prospectively included before being referred for coronary angiography. All patients underwent CZT MPR before invasive coronary angiography (ICA) and coronary physiology assessment.

Prognostic significance of severe coronary microvascular dysfunction post-PCI in patients with STEMI: A systematic review and meta-analysis.

Coronary microvascular dysfunction (CMVD) is common and associated with poorer outcomes in patients with ST Segment Elevation Myocardial Infarction (STEMI). The index of microcirculatory resistance (IMR) and the index of hyperemic microvascular resistance (HMR) are both invasive indexes of microvascular resistance proposed for the diagnosis of severe CMVD after primary percutaneous coronary intervention (pPCI). However, these indexes are not routinely assessed in STEMI patients.

Prognosis of Coronary Atherosclerotic Burden in Non-Ischemic Dilated Cardiomyopathies.

Background: Atherosclerosis is associated with a worse prognosis in many diseases such as ischemic cardiomyopathy, but its impact in non-ischemic dilated cardiomyopathy (dCMP) is lesser known. Our aim was to study the prognostic impact of coronary atherosclerotic burden (CAB) in patients with dCMP.

Methods: Consecutive patients with dCMP and left ventricular (LV) dysfunction diagnosed by concomitant analysis of invasive coronary angiography (ICA) and CMR imaging were identified from registry-database.

Comparison of Cadmium Zinc Telluride ECG-gated SPECT equilibrium radionuclide angiocardiography to magnetic resonance imaging to measure right ventricular volumes and ejection fraction in patients with cardiomyopathy.

Aims: The objective of this study was to determine the accuracy of right ventricular function (RVF) assessed by Cadmium Zinc Telluride ECG-gated SPECT equilibrium radionuclide angiocardiography (CZT-ERNA).

Methods And Results: Twenty-one consecutive patients with cardiomyopathy (aged 54 ± 19 years; 62% male) were included. RV ejection fraction (EF) and volumes were analyzed by CZT-ERNA and compared with values obtained by cardiac magnetic resonance imaging (CMR).
