Objective: Stress-only myocardial perfusion imaging protocol has a prognostic value similar to that of a stress-rest protocol. The aim of the study was to assess stress myocardial perfusion by gated single photon emission computed tomography (SPECT) myocardial perfusion imaging (GSMPI) in patients who had a normal stress-only study 4.9 years (mean time) before and assess the possible influence of various factors on the results.

Myocardial perfusion scintigraphy (MPS) as a non-invasive diagnostic imaging procedure and certain biomarkers associated with myocardial ischemia (ISCH), such as ischemia-modified albumin (IMA), neuropeptide Y (NPY), N-terminal pro b-type natriuretic peptide (NT-proBNP), and high-sensitivity troponin T (hsTnT) could probably aid in the detection of myocardial infarction.
Methods: Between December 2011 and June 2012, we prospectively analyzed patients who underwent a MPS study with the clinical question of myocardial ISCH.
Pilot study to evaluate the safety and feasibility of intracoronary CD133(+) and CD133(-) CD34(+) cell therapy in patients with nonviable anterior myocardial infarction.

Article Synopsis
- The study investigated the long-term effects of administering progenitor cells via intracoronary infusion in patients with chronic ischemic cardiomyopathy, showing promising results in improving heart function.
- Twenty-four patients participated, with half receiving the cell treatment and the other half continuing standard medical therapy; the treatment group showed significant improvements in heart metrics over time.
- Overall, the infusion was deemed safe, with notable enhancements in heart performance, while the control group exhibited deterioration in heart condition, highlighting the potential benefits of this therapy.
