Previous studies have shown that both hawthorn and honey-processed hawthorn (HH) can prevent heart injury in acute myocardial ischemia (AMI). Hawthorn pectin (HP) and stir-fried hawthorn pectin (FHP) have been identified as protective agents against AMI, with the effects closely related to their structural characteristics. This study aims to investigate the effects of pectin of HH (HHP) in preventing AMI. Results showed that the esterification degree, the content of galacturonic acid, and the viscosity-average molecular weight of HHP were lower than those of HP. Rats pretreated with HHP exhibited improvements when suffering from AMI in maintaining the levels of myocardial enzyme as well as indicators related to oxidative stress. In terms of gut microbiota and short-chain fatty acids, HHP enriched Monoglobus and increased the content of propionic acid, while HP enriched Lachnospira and increased the content of acetic acid in the intestine. The different effects of HHP from HP on regulating gut microbiota and short-chain fatty acids might be attributed to structural alterations of the HHP after processing of hawthorn. These results contributed to the established connection between pectin consumption and its protective effect from AMI.

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Angina V: Nursing Management

Angina, a symptom of myocardial ischemia, requires a structured nursing management approach to ensure effective care and prevent complications like myocardial infarction. Comprehensive nursing care involves assessing, diagnosing, planning, implementing interventions, and evaluating outcomes, all tailored to the individual patient's needs.Patient AssessmentNursing assessment begins with a detailed subjective evaluation of symptoms, which typically include chest pain or pressure radiating to the...

Introduction Cardiac Emergencies

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...
