Background And Objective: This was a cross-sectional study in which the values of sensitivity and specificity of myocardial perfusion study with (99)mTc-Tetrofosmina protocol in a day after stimulation with dipyridamole were determined in a population of women. We also assessed the relationship with coronary vascular territories, based on coronary angiography.
Patients And Method: We studied retrospective medical records of 202 women with suspected ischemic heart disease tested on myocardial perfusion who also underwent coronary angiography.
Results: The values of sensitivity and specificity for the population were 87.16% and 81.48% respectively. For the coronary artery territory, the values of sensitivity and specificity for the DA artery were 68.75% and 77.78% respectively, while these were 60.0% and 81.51% for the Cx. Finally, the values for the CD were 69.88 and 72.27%, respectively.
Conclusions: The myocardial perfusion test stimulation/rest has a high diagnostic validity for the disease in women with suspected ischemic heart disease.

Diagnostic Feasibility and Accuracy of Cardiac Positron Emission Tomography (PET) in the Evaluation of Ischemic Heart Disease.

Cardiac Positron Emission Tomography (PET) can be used for the assessment of myocardial perfusion. Compared to other cardiac imaging techniques, notably Single Photon Emission Computer Tomography (SPECT), cardiac PET offers superior image resolution, higher accuracy, quantitative measures of myocardial perfusion, lower radiation exposure, and shorter image acquisition time. However, PET tends to be costlier and less widely available than SPECT due to the specialized equipment needed for generating the necessary radiotracers.

Ischaemia-reperfusion time differences in ST-elevation myocardial infarction in very young patients: a cohort study.

Introduction: ST-elevation myocardial infarction (STEMI) is one of the most prevalent presentations in young patients. It is essential to emphasise that each minute of delay in providing medical care is negatively correlated to the patient's prognosis. The present study was carried out to evaluate the ischaemia-reperfusion times in patients ≤40 years of age versus individuals >40 years of age and their association with mortality and major adverse cardiac event (MACE) over the long term.

Ventricular arrhythmias induced by ischemia/reperfusion injury limits the therapeutic effect of early reperfusion therapy for acute myocardial infarction. This study investigated the protective effects of the β2-adrenergic receptor (β2-AR) agonist clenbuterol against ischemia/reperfusion-induced arrhythmias and the underlying mechanism. Anesthetized rats were subjected to 10-min left coronary artery occlusion and 10-min reperfusion in vivo.

Background: The fluorescent dye indocyanine green (ICG) has been used to identify anatomical structures intraoperatively in coronary artery bypass grafting (CABG). This study aimed to evaluate the feasibility of using ICG to assess graft patency and territorial distribution of myocardial reperfusion during CABG.
Methods: Porcine arrested hearts (n = 18) were used to evaluate territorial distribution of native coronary arteries and of a coronary bypass constructed with porcine saphenous vein graft (SVG) using ICG.
