Cardiac CT angiography (CTA) is an ideal tool to investigate cardiac and noncardiac causes of acute chest pain. In this case, careful planning of the CTA acquisition and reconstruction limits permitted not only the exclusion of aortic dissection and provided high resolution images of coronary anatomy but also showed a concordant abnormality in myocardial perfusion and ventricular function in the setting of an acute coronary syndrome. Detailed planning of every CTA acquisition reconstruction protocol is essential to obtain the information necessary for clinical decision-making strategies and interventions in the patient with chest pain.

Effect of del Nido cardioplegia in patients with reduced left ventricular ejection fraction: A meta-analysis.

Department of Cardiothoracic Surgery, Lankenau Heart Institute, Wynnewood, PA, USA.
Purpose: Research on the safety and efficacy of del Nido cardioplegia in adult patients with reduced left ventricular ejection fraction (LVEF) is limited. We evaluated the effect of del Nido cardioplegia on early outcomes of cardiac surgery in this cohort.
Methods: PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were searched through August 2024 to conduct a meta-analysis comparing del Nido to other cardioplegia in adult patients with reduced LVEF (≤50%).

Ischemic heart disease is the leading cause of death worldwide. Reduced oxygen supply and myocardial hypoxia lead to tissue damage and impairment of the heart function. To the best of our knowledge, the primary functional effects of hypoxia in the multicellular model of living myocardial slices (LMSs) have not been investigated so far.

Physical activity improves myocardial structure, function and resilience via complex, incompletely defined mechanisms. We explored effects of 1-2 wks swim training on cardiac and systemic phenotype in young male C57Bl/6 mice. Two wks forced swimming (90 min twice daily) resulted in cardiac hypertrophy (22% increase in heart:body weight, P<0.

Cardiogenic shock represents a critical condition in which the heart is unable to maintain adequate circulation leading to insufficient tissue perfusion and end-organ failure. Temporary mechanical circulatory support offers the potential to stabilize patients, provide a bridge-to-recovery, provide a bridge-to-decision, or facilitate definitive heart replacement therapies. Although randomized controlled trials have been performed in infarct-related cardiogenic shock and refractory cardiac arrest, the optimal timing, appropriate patient selection, and optimal implementation of these devices remain complex and predominantly based on observational data and expert consensus, especially in non-ischaemic shock.

Adenosine is extensively utilized in myocardial stress perfusion imaging for the detection and risk stratification of coronary artery disease. It has a well-established safety profile. The majority of the undesirable effects experienced during adenosine infusion are transient (owing to its brief half-life of ~10 s) and arise from the stimulation of receptors in the atrio-ventricular (AV) node (AV block) and bronchial smooth muscles (bronchospasm).
