Cardiac causes account for nearly half of all deaths in patients with end-stage renal disease (ESRD). Coronary artery disease (CAD) is present in 38% - 40% of patients starting dialysis. Both traditional and chronic kidney disease-related cardiovascular risk factors contribute to this high prevalence rate. In patients with ESRD, CAD--particularly acute myocardial infarction--is underdiagnosed. Dobutamine stress echocardiography and, to a lesser extent, stress myocardial perfusion imaging have proved useful in screening for CAD in such patients. Coronary artery calcium scoring is less useful. Acute myocardial infarction is associated with high short- and long-term mortality in dialysis patients. Cardiac troponin I appears to be more specific than cardiac troponin T or CK-MB in the diagnosis of acute myocardial infarction.

Myocardial infarction (MI), a leading cause of global mortality, often leads to heart failure and impaired quality of life. This randomized controlled trial evaluated Salvia miltiorrhiza (SM), a traditional Chinese herb containing bioactive compounds like tanshinone IIA and salvianolic acid A, as an adjunct therapy for acute MI. SM is known for anti-inflammatory, antioxidant, anticoagulant and microcirculatory benefits.

Life-threatening sepsis with high mortality and morbidity is an important cause of acute kidney injury and myocardial dysfunction. In this study, we investigated the protective effect of Micromeria congesta (MC) against kidney and heart damage caused by lipopolysaccharide (LPS) used as a sepsis model. Control, LPS, LPS + 25 mg/kg MC and LPS + 50 mg/kg MC groups were established from rats for the study.

Background: Chronic low-grade inflammation is a well-known risk factor for coronary heart disease (CHD) and future cardiovascular events. Anti-inflammatory therapy can reduce the risk of ischemic cardiovascular disease (CVD) events following myocardial infarction (MI). However, it remains unknown to what extent inflammation at the time of an acute event predicts long-term outcomes.

Sodium-glucose co-transporter 2 (SGLT2) inhibitors have demonstrated potential neuroprotective and cardioprotective effects in preliminary studies. This study evaluates the efficacy of empagliflozin (EMPA) in reducing ischemia/reperfusion damage in both the brain and heart using rat models. Ischemic stroke and myocardial infarction (MI) were induced in male Sprague-Dawley rats, which were randomized into three groups: (1) Control (no EMPA), (2) Acute treatment (EMPA, 10 mg/kg IV, administered 10 min before ischemia and 1 min before reperfusion), and (3) Chronic treatment (EMPA, 20 mg/kg in food for 7 days before ischemia).

Objective: During acute myocardial infarction (AMI), ferroptosis occurs in cardiomyocytes, leading to ventricular remodeling. To investigate the influence of exosomes (Exo) derived from adipose mesenchymal stem cells (AD-MSCs) on cardiomyocytes, a therapeutic approach to resolve AMI may be discovered.
Methods: The Exo of AD-MSCs was isolated and identified, and internalized into cardiomyocytes.
