Cardiovascular disease is the most common disease in the world and the first among the causes of human death. Its morbidity and mortality increase annually, but no effective treatment is available. Therefore, new drugs should be developed to treat cardiovascular disease. (Michx.) Hulten () is an important Mongolian medicine in China and elicits protective effects on cardiovascular health. In this study, liquid chromatography-mass spectrometry (LC-MS) combined with network pharmacology was used to screen the main active ingredients and confirm that bellidifolin was one of the main components for the treatment of ischemic heart disease. Then, rat myocardial (H9c2) cells injury model induced by hydrogen peroxide (HO) was established to verify the effect of bellidifolin on oxidative stress stimulation, including determination of antioxidant enzyme activity and apoptosis. Transcriptome sequencing, qRT-PCR, and western blot were performed to further verify the antioxidant stress mechanism of bellidifolin. Results showed that bellidifolin pretreatment decreased the rate of apoptosis and the levels of lactate dehydrogenase (LDH), creatine kinase (CK), and alanine aminotransferase (ALT). Conversely, it increased the contents of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in a dose-dependent manner, indicating that bellidifolin caused a protective effect on cardiomyocyte injury. Bellidifolin minimized the HO-induced cell injury by activating the PI3K-Akt signal pathway and downregulating glycogen synthase kinase-3β (GSK-3β) and p-Akt1/Akt1. Therefore, this work revealed that has a good development prospect as an edible medicinal plant in cardiovascular disease. Its bellidifolin component is a potential therapeutic agent for cardiovascular disease induced by oxidative stress damage.

Heart failure (HF), a chronic and progressive disease, is increasing in prevalence worldwide and is associated with increased hospitalizations and death. Despite notable improvements in medical therapy for HF, patients are still at risk of future negative outcomes. Current guidelines recommend four classes of medication for treating patients with HF, deemed guideline-directed medical therapy (GDMT).

These two conditions share common risk factors and often coexist, leading to a complex interplay that alters the clinical course of each other. The pathophysiology of HFpEF is multifaceted and intricately linked, with atrial disease serving as a common pathophysiological pathway.

Background: Heart failure (HF) significantly impacts the cardiovascular health of children and adolescents. This study aims to assess epidemiologic trends in HF across sex, age, region, and time period.
Methods: The number and age-standardized rate (ASR) of prevalence and years lived with disability (YLDs) were derived from the Global Burden of Disease Study 2019.

Purpose Of Review: The present review describes the available literature on the physiologic mechanisms that modulate hunger, appetite, satiation, and satiety with a particular focus on well-established and emerging factors involved in the classic satiety cascade model.
Recent Finding: Obesity is a significant risk factor for numerous chronic conditions like cancer, cardiovascular diseases, and diabetes. As excess energy intake is considered by some to be the primary driver of weight gain, tremendous collective effort should be directed toward reducing excessive feeding at the individual and population levels.
