The paper reports results of endovascular treatment of 66 patients with post-infarction cardiosclerosis. It was shown that normalization of coronary circulation in patients with viable hibernating myocardium in the zone of the affected artery not only eliminates the signs of chronic ischemia and slows down post-infarction heart remodeling but also restores the lost functions of hibernating myocardium which has beneficial influence on prognosis of the disease. Functioning of hibernating myocardium depends on the timely restoration of coronary circulation.

The Relationship Between the Type of ST-Segment Elevation in Acute Anterior Wall Myocardial Infarction and Left Ventricular Ejection Function.

Internal Medicine Department, Shalamar Hospital, Lahore, PAK.
Introduction: Acute anterior wall myocardial infarction (AWMI), when presenting with ST-segment elevation on an electrocardiogram (ECG), represents a form of ST-elevation myocardial infarction (STEMI) caused by a significant reduction in coronary blood flow to the heart muscle. The shape of the ST-segment elevation, whether it is concave, convex, or straight, has been associated with different levels of left ventricular ejection fraction (LVEF), which is an important indicator of cardiac function and prognosis.
Objective: To investigate the relationship between the type of ST-segment elevation on ECG and LVEF measured 48 hours after the onset of myocardial infarction in patients with AWMI.

The influence of computed tomography attenuation correction (CTAC) on the accuracy of diagnosing viable myocardium using Tc-99m-MIBI dedicated cardiac cadmium-zinc-telluride (CZT) single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) combined with F-18-FDG Positron Emission Tomography/Computed Tomography (PET/CT) metabolic imaging, compared with conventional SPECT MPI, remains to be fully elucidated. To evaluate the impact of CTAC on the accuracy of diagnosing viable myocardium using Tc-99m-MIBI dedicated cardiac CZT SPECT MPI combined with F-18-FDG PET/CT, compared to conventional SPECT MPI. 193 patients underwent CZT SPECT and F-18-FDG PET/CT imaging, while 39 patients underwent conventional SPECT and F-18-FDG PET/CT imaging, with both groups utilizing CT for attenuation correction.

Background To assess the feasibility of a machine learning (ML) approach using radiomics features of perfusion defects on rest myocardial perfusion imaging (MPI) to detect the presence of hibernating myocardium. Methodology Data of patients who underwent 99mTc-sestamibi MPI and 18F-FDG PET/CT for myocardial viability assessment were retrieved. Rest MPI data were processed on ECToolbox, and polar maps were saved using the NFile PMap tool.

Objective: Chronic ischemia-related cavernous dysfunction is considered irreversible. However, in certain patients, cavernous function appears to recover with penile revascularization. In this study, we investigated a potential cavernous dysfunction reversibility from a clinical perspective.
