The remarkable advances in cardiac surgery over the last 50 years have led to the concept of "routine" open heart surgery. The introduction of novel surgical technologies, methods of anesthesiology and intensive care allowing for a reduction morbidity and mortality at perioperative period. The development of intraoperative myocardial protection has been impressive too. A tremendous body of literature has documented the physiologic basis of current cardioprotective methods and debate over the optimal technique. We tried to review current trends and future perspectives of myocardial protection in this article.

Background: Patients with a left ventricular ejection fraction ≤ 35% are at increased risk of sudden cardiac death (SCD) within the first months after a myocardial infarction (MI). The wearable cardioverter defibrillator (WCD) is an established, safe and effective solution which can protect patients from SCD during the first months after an MI, when the risk of SCD is at its peak. This study aimed to evaluate the cost-effectiveness of WCD combined with guideline-directed medical therapy (GDMT) compared to GDMT alone, after MI in the English National Health Service (NHS).

Mitochondrial dysfunction and ferroptosis play crucial roles in myocardial ischemia/reperfusion (I/R) following heart transplantation. Microsomal glutathione s transferase 1 (MGST1) is widely distributed in mitochondria and has a protective effect against ferroptosis, and its involvement in myocardial I/R injury has not yet been elucidated. In this study, donor hearts from C57BL/6 male mice were subjected to 12 h of ex-vivo cold ischemia treatment and transplanted into the abdomen of recipient mice for 24 h of reperfusion.

Purpose: Targeting mitochondrial ferroptosis presents a promising strategy for mitigating myocardial ischemia-reperfusion (I/R) injury. This study aims to evaluate the efficacy of the mitochondrial-targeted ferroptosis inhibitor SS-31@Fer-1 (elamipretide@ferrostatin1) in reducing myocardial I/R injury.
Methods: SS-31@Fer-1 was synthesized and applied to H9C2 cells subjected to hypoxia/reoxygenation (H/R) to assess its protective effects.

Background: Mitochondrial dysfunction plays a crucial role in the development of a variety of diseases, notably neurodegenerative disorders, cardiovascular diseases, metabolic syndrome, and cancer. Natural saponins, which are intricate glycosides characterized by steroidal or triterpenoid structures, have attracted interest due to their diverse pharmacological benefits, including anti-inflammatory, antiviral, and anti-aging effects.
Purpose: This review synthesizes recent advancements in understanding mitochondrial dysfunction and explores how saponins can modulate mitochondrial function.

Background: Exosomes sourced from mesenchymal stem cells (MSC-EXOs) have become a promising therapeutic tool for sepsis-induced myocardial dysfunction (SMD). Our previous study demonstrated that Apelin pretreatment enhanced the therapeutic benefit of MSCs in myocardial infarction by improving their paracrine effects. This study aimed to determine whether EXOs sourced from Apelin-pretreated MSCs (Apelin-MSC-EXOs) would have potent cardioprotective effects against SMD and elucidate the underlying mechanisms.
