Cardiac ischemia-reperfusion stimulates the renin-angiotensin system (RAS) associated with elevated levels of circulating angiotensin II. Numerous studies demonstrate that the antagonist for the angiotensin II type 1 receptor, losartan improves cardiac function in animal models of ischemia-reperfusion. Molecular mechanisms of the cardioprotective effects of RAS inhibitors on cardiac ischemia-reperfusion remain poorly understood, and are not associated with the anti-hypertensive action of these drugs. This Commentary focuses on the study published in the Journal of Pharmacy and Pharmaceutical Sciences, 2015, 18:112-123, that elucidates the role of SIRT3 in the cardioprotective action of losartan against ischemic-reperfusion injury. We provide comprehensive discussion of the role of mitochondria in the cardioprotective effects of losartan through SIRT3. This article is open to POST-PUBLICATION REVIEW.

This study investigates the role of Fundc1 in cardiac protection under high-altitude hypoxic conditions and elucidates its underlying molecular mechanisms. Using cardiomyocyte-specific knockout ( ) mice, we demonstrated that deficiency exacerbates cardiac dysfunction under simulated high-altitude hypoxia, manifesting as impaired systolic and diastolic function. Mechanistically, we identified that Fundc1 regulates cardiac function through the mitochondrial unfolded protein response (mito-UPR) pathway.

The long-term cost-effectiveness of empagliflozin for the treatment of heart failure (HF) in the Philippines remains unclear. This study aims to determine the economic benefit of adding empagliflozin to the standard of care (SoC) vs the SoC alone for HF in the Philippines.

Ischaemic heart disease is a consequence of coronary atherosclerosis, and atherosclerosis is a systemic inflammatory disease. The spleen releases various immune cells in temporally distinct patterns. Neutrophils, monocytes, macrophages, B cells and T cells execute innate and adaptive immune processes in the coronary atherosclerotic plaque and in the ischaemic myocardium.

Background: ST-segment elevation myocardial infarction (STEMI) is treated with immediate primary percutaneous coronary intervention (pPCI) to restore coronary blood flow in the acutely ischaemic territory, but is associated with reperfusion injury limiting the benefit of the therapy. No treatment has proven effective in reducing reperfusion injury. Transcoronary hypothermia has been tested in clinical studies and is well tolerated, but is generally established after crossing the occlusion with a guidewire therefore after initial reperfusion, which might have contributed to the neutral outcomes.

Coronary artery disease (CAD)-cardiovascular condition occuring due to atherosclerotic plaque accumulation in the epicardial arteries-is responsible for disabilities of millions of people worldwide and remains the most common single cause of death. Inflammation is the primary pathological mechanism underlying CAD, since is involved in atherosclerotic plaque formation. Glucagon-like peptide-1 (GLP-1) is a peptide hormone which role extends beyond well-known carbohydrates metabolism.
