Heart Failure Classification and Its Stages
Understanding the Heart Failure Classification System
According to the latest clinical guidelines, heart failure is categorized into four distinct stages. These classifications help doctors assess the severity of a patient's condition and determine the most appropriate treatment plan.
Class I: Mild Heart Failure
Stage I is characterized by the absence of symptoms during regular daily activities. Patients may only experience signs of heart failure during intense physical exertion. At this stage, individuals typically face no restrictions in their everyday routines or exercise capacity.
Class II: Mild to Moderate Heart Failure
In Stage II, patients begin to notice mild symptoms such as fatigue or shortness of breath during routine activities like walking or climbing stairs. Although daily life is only slightly affected, some limitations in physical activity may become apparent and should be taken into consideration.
Class III: Moderate to Severe Heart Failure
Stage III indicates a more advanced form of heart failure, where symptoms appear even during minimal physical effort. This level significantly impacts a person's ability to carry out normal daily tasks, and physical activity is noticeably restricted as a result.
Class IV: End-Stage Heart Failure
Stage IV represents the most severe form of heart failure. At this point, individuals are often unable to perform any physical activity without experiencing discomfort. Symptoms like breathlessness can occur even at rest, and patients may require bed rest. Additionally, lying flat at night can worsen breathing difficulties, making sleep challenging without elevation of the upper body.
