What are the symptoms of heart failure? You need to know the four stages.
Model: Congenital Heart Disease Intervention Training Model (XXS003)
Heart failure, abbreviated as HF, is a complex clinical syndrome caused by structural or functional abnormalities of the heart. It primarily affects the elderly population and has high incidence and mortality rates. Understanding the symptoms related to heart failure and taking early preventive measures can effectively reduce the occurrence of heart failure.
How does heart failure occur?
Heart failure occurs when the heart is pathologically damaged. Cardiac damage can be categorized as acute or chronic. Chronic damage includes conditions such as hypertension, coronary artery disease, and sequelae of myocarditis, which lead to a decline in cardiac function. Acute damage includes conditions like extensive acute myocardial infarction and acute severe myocarditis, which rapidly injure a significant amount of myocardium and result in heart failure.
How is heart failure classified into stages?
Heart failure can be classified into stages based on the degree of left ventricular or right ventricular dysfunction and the extent of damage. Currently, the international academic community has standardized the methods and criteria for staging heart failure. There are two main categories: one for acute heart failure and another for chronic heart failure. Acute heart failure has two staging methods: one is the Killip classification for acute cardiac dysfunction caused by myocardial infarction, and the other is the Stevenson classification for heart failure not caused by acute myocardial infarction. These two methods are used to assess the severity of acute heart failure. Chronic heart failure is evaluated using the New York Heart Association (NYHA) classification.
Criteria for different stages of heart failure
Taking chronic heart failure as an example, the NYHA functional classification is based on the extent of heart failure's impact on the patient's physical activity. If heart failure symptoms are evident even at rest, the patient is classified as having class IV chronic heart failure. If the patient's activity is unrestricted and the disease's impact is not severe, it is classified as class I chronic heart failure. If heart failure symptoms occur with activity but not at rest, the patient falls into class II or class III heart failure. If symptoms appear after walking more than 100 meters during daily physical activity, it is classified as class II heart failure. If symptoms occur before reaching 100 meters of activity, it is classified as class III heart failure. The classification is based on the degree of impact on exercise tolerance.
Heart Failure Symptoms
Heart failure is a disease with many stages. The onset may be rapid, or it may progress more gradually. But once heart failure starts; it usually becomes a lifelong disease that patients have to learn to live with. Living with heart failure can be easier once you understand the symptoms and can communicate with your health care providers to make sure you are receiving the right care.
The following list of symptoms can be a place to start discussions with your caregiver(s):
Shortness of breath (dyspnea) when you exert yourself or when you lie down
Fatigue and weakness
Swelling (edema) in your lower extremities (feet, ankles, legs)
Rapid or irregular heartbeat
Reduced ability to exercise
Persistent cough or wheezing
Swelling of your abdomen (ascites)
Very rapid weight gain from fluid retention
Lack of appetite
Difficulty concentrating
The Congenital Heart Disease Intervention Training Model is a cutting-edge simulation tool designed to enhance the study and treatment of heart failure, specifically focusing on atrial septal defects (ASD) and other common lesions such as patent foramen ovale (PFO), ventricular septal defects (VSD), and patent ductus arteriosus (PDA). This model provides a detailed representation of the femoral vein, iliac vein, inferior vena cava (IVC), left atrium, and right atrium, with a specific focus on the atrial septum containing an ASD lesion. What sets this model apart is its customization options, allowing researchers and medical professionals to tailor the location and dimensions of the ASD according to their specific requirements. Additionally, common lesions can be added to the model, creating a versatile and comprehensive training platform.
By utilizing the Congenital Heart Disease Intervention Training Model, researchers and healthcare practitioners can gain valuable insights into the mechanisms and treatment options for heart failure associated with congenital heart defects. The realistic simulation of the heart's anatomy and the presence of ASD and other lesions allows for hands-on training and practice of interventional procedures, specifically those involving the occlusion of atrial septal defects. This model offers a unique opportunity to study the pathophysiology of heart failure caused by congenital heart defects and further explore the efficacy of various treatment approaches. By customizing the model based on patient-specific data files, such as CT scans or CAD files, medical professionals can simulate real-life scenarios, improving their diagnostic and interventional skills and ultimately enhancing patient care and outcomes. The Congenital Heart Disease Intervention Training Model represents a significant advancement in medical education and research, providing a valuable tool for studying heart failure and developing innovative treatment strategies.
