Background: Effective myocardial reperfusion in ST-Elevation Myocardial Infarction (STEMI) remains challenging despite advancements in primary percutaneous coronary intervention (PCI). This study evaluates the impact of thrombus aspiration (TA) and saline autotransfusion (SAT) compared to standard PCI (NOTA) on coronary flow dynamics and myocardial perfusion.
Research Design And Method: This prospective cohort study enrolled 157 STEMI patients who underwent primary PCI. Participants were divided into two groups: TA+SAT ( = 80) and NOTA ( = 77). Clinical parameters such as blood pressure, ejection fraction, ST-segment resolution, thrombolysis in myocardial infarction (TIMI) flow grades, corrected TIMI frame count (CTFC), and myocardial infarction (MI) location were assessed.
Results: Patients in the TA+SAT group exhibited significantly better short-term myocardial reperfusion, as indicated by superior ST-segment resolution ( = 0.010) and lower CTFC values ( < 0.001). Blood pressure was significantly lower in the TA+SAT group ( = 0.042). However, ejection fraction improvement at one month was not statistically significant. TIMI and TMPG flow grades were comparable between groups.
Conclusion: The TA+SAT approach demonstrated improved coronary flow dynamics and better short-term myocardial reperfusion in STEMI patients without additional pharmacological interventions. These findings suggest that TA+SAT may serve as a valuable adjunct to PCI, warranting further investigation into its long-term clinical benefits.

Clinical Outcomes of Immediate Versus Staged Revascularization of Nonculprit Arteries in Patients With Acute Coronary Syndrome: A Systematic Review and Meta-Analysis.

Background: Recent guidelines for acute coronary syndrome (ACS) with multivessel coronary artery disease (MVD) recommend revascularization of non-culprit lesions following primary percutaneous coronary intervention (PCI). However, the optimal timing for this procedure-whether immediate or staged-remains uncertain.
Methods: A comprehensive search using PubMed (MEDLINE), Cochrane Central, and Google Scholar was conducted to identify studies comparing clinical outcomes between immediate and staged revascularization approaches in patients with MVD undergoing PCI.
Automated fibrosis segmentation from wideband post-contrast mapping in an animal model of ischemic heart disease with implantable cardioverter-defibrillators.

Purpose: Post-contrast mapping has proven promising for automated scar segmentation in subjects without ICDs, but this has not been implemented in patients with ICDs. We introduce an automated cluster-based thresholding method for maps with an ICD present and compare it to manually tuned thresholding of synthetic LGE images with an ICD present and standard LGE without an ICD present.
Methods: Seven swine received an ischemia-reperfusion myocardial infarction and were imaged at 3 T 4-5 weeks post-infarct with and without an ICD.

This article reviews the role of different types of T lymphocyte subpopulations in pathological cardiac fibrosis remodeling. T helper 17 (Th17) cells are implicated in promoting the development of pathological cardiac fibrosis remodeling, while regulatory T (Treg) cells exert an immunosuppressive functions as negative regulators, attributing to their interleukin-10 (IL-10) secretion and functional phenotype. Th1 and Th2 cells are involved in different stages of the inflammatory response in pathological cardiac fibrosis remodeling, and their influence varies according to the pathological mechanisms of different cardiac diseases.

Due to their high specificity and exclusive cardiac myocyte sensitivity, cardiac troponins T and I (cTnT, cTnI) are currently regarded as ideal biomarkers to identify cardiomyocyte damage, myocardial injury, myocardial infarction, and chronic heart failure. In fact, cTnI is considered the most reliable biomarker for diagnosing heart-related issues. This study aimed to investigate the effects of age, gender, and exercise training on serum cTnI levels and various parameters related to the cardiovascular capacity of Caspian horses.
