Heart failure stages (Class I-IV) track symptom severity, from no limitation (Class I) to symptoms even at rest (Class IV), with common signs including shortness of breath, fatigue, leg swelling (edema), rapid heartbeat, and coughing, worsening as the heart pumps less effectively, causing fluid buildup and reduced oxygen supply.
Stages of heart failure
class 1 – you don't have any symptoms during normal physical activity. class 2 – you're comfortable at rest, but normal physical activity triggers symptoms. class 3 – you're comfortable at rest, but minor physical activity triggers symptoms.
Another study showed that the survival rates of people with chronic heart failure were: 80% to 90% for one year. 50% to 60% for year five. 30% for 10 years.
Stage 3 congestive heart failure
“In the third stage, you may be comfortable at rest, but notice significant limitations during physical activity. Even light exercise can bring on symptoms such as heart palpitations, fatigue and shortness of breath.
End-stage Congestive Heart Failure (CHF) involves severe, relentless symptoms like extreme breathlessness (dyspnea) even at rest, profound fatigue, significant swelling (edema) in legs, abdomen, and neck, a persistent, hacking cough (sometimes pink/frothy), and potential cognitive issues, all stemming from the heart's inability to pump effectively, leading to fluid buildup (congestion) and poor circulation (hypoperfusion). Patients often experience rapid or irregular heartbeats, loss of appetite, weight changes, and general weakness, indicating the need for palliative care focusing on comfort.
Shortness of breath with activity or when lying down. Fatigue and weakness. Swelling in the legs, ankles and feet. Rapid or irregular heartbeat.
Cardiac arrest is the mode of demise in 30–50% of patients with heart failure and a reduced ejection fraction (HFrEF), and conversely, systolic dysfunction is a major risk factor for sudden cardiac death in the community.
End-stage heart failure symptoms
When that happens, you experience symptoms related to the poor circulation of blood: Shortness of breath or difficulty breathing. Edema (fluid buildup and swelling) in the legs, feet and torso.
It may be advisable to avoid travelling to high altitudes or hot, humid places because this may put extra strain on your heart. Flying won't usually cause problems, but if your heart failure is severe, your legs and ankles may swell and breathing may become more difficult.
Signs of Worsening Heart Failure
Chronic heart failure patients also showed significantly lower gait speed, stride length, gait cycle and step length (p<0.05).
Many people first realize their heart failure is getting worse when they notice gaining more than two or three pounds in a day or more than five pounds in a week. This gain may be due to retaining fluids since the heart is not working properly.
Frequently observed signs or symptoms, which can occur in isolation or in combination and can thus be used as “red flags” or warning signs include: Shortness of breath (dyspnea) or noticeably reduced exercise capacity. Chest pain (angina pectoris)
Worsening heart failure – a specific phase in the continuum of HF. WHF is defined by escalating signs and symptoms of HF in patients with chronic HF despite optimal therapy, also implying the need for urgent therapy escalation [29–31].

ACE inhibitors
Angiotensin-converting enzyme (ACE) inhibitors work by relaxing and opening up your blood vessels, which makes it easier for your heart to pump blood around the body. Examples of ACE inhibitors include ramipril, captopril, enalapril, lisinopril and perindopril.
Your chest may feel heavy or like someone is squeezing your chest or heart. You may also feel a sharp, burning pain in your chest. You may feel the pain under your breastbone (sternum, so the pain is called substernal) or in your neck, arms, stomach, jaw, or upper back.
A person with end-stage heart failure who is beginning to experience the stages of dying will have symptoms such as: Decreased responsiveness. Increased restlessness. Difficulty speaking or moving.
Heart failure (HF), also known as congestive heart failure (CHF), is a complex clinical syndrome characterized by the heart's inability to pump blood effectively due to structural or functional impairments.
Worsening heart failure symptoms often involve increased shortness of breath (especially when lying down or sleeping), rapid weight gain from fluid buildup (like in legs, ankles, or abdomen), significant fatigue, a persistent cough with white/pink phlegm, increased swelling, heart palpitations, and mental confusion, signaling a need for prompt medical attention to prevent serious complications.
When your heart failure is not very bad, your health care provider may not place you on a fluid restriction. As your heart failure becomes worse, your health care provider may limit your fluids to 6-9 cups (1.5-2 liters) a day. Having other conditions like kidney disease may factor into their decision, too.
The blood gas exchange disorder and decreased cardiac output caused by pulmonary congestion and edema in chronic heart failure inevitably lead to a decrease in oxygen partial pressure and oxygen saturation.
