Overview

The classic symptoms of heart failure include dyspnea, fatigue, and fluid retention. Patients with heart failure present in different ways. Some patients present with exercise intolerance but show little evidence of congestion or edema. Other patients present with mild symptoms of edema and pulmonary congestion. The ejection fraction is usually below 35% in patients who are symptomatic with systolic heart failure.

Symptoms

• Table bellow shows Symptoms and signs of heart failure:

Typical symptoms	More specific signs
Breathlessness Orthopnoea Paroxysmal nocturnal dyspnoea Reduced exercise tolerance Fatigue Tiredness Increased time to recover after exercise Ankle swelling	Elevated jugular venous pressure Hepatojugular reflux Third heart sound (gallop rhythm) Laterally displaced apical impulse
Less typical symptoms	Less specific signs
Nocturnal cough Wheezing Bloated feeling Loss of appetite Confusion (especially in the elderly) Depression Palpitation Dizziness Syncope Bendopnea	Weight gain (>2 kg/week) Weight loss (in advanced HF) Tissue wasting (cachexia) Cardiac murmur Peripheral oedema (ankle, sacral, scrotal) Pulmonary crepitations Pleural effusion Tachycardia Irregular pulse Tachypnoea Cheyne-Stokes respiration Hepatomegaly Ascites Cold extremities Oliguria Narrow pulse pressure

The above table adopted from 2021 ESC Guideline

Symptoms of Left Sided Congestive Heart Failure

The left side pumps blood into the systemic circulation, while the right side pumps blood into the pulmonary circulation. Although left-sided heart failure will reduce forward cardiac output to the systemic circulation, the initial symptoms are often due to pulmonary congestion. In systolic dysfunction, the ejection fraction is decreased, leaving an abnormally elevated volume of blood in the left ventricle. In diastolic dysfunction, left ventricular end-diastolic pressure will be high. This increase in volume or pressure backs up to the left atrium and then into the pulmonary veins. Increased volume or pressure in the pulmonary veins impairs the normal drainage of the alveoli and favors the flow of fluid from the capillaries to the lung parenchyma, causing pulmonary edema. This impairs gas exchange and results in hypoxemia. Thus, left-sided heart failure often presents with respiratory symptoms including:

• Dyspnea
• Frothy sputum
• Nocturnal cough
• Orthopnea
• Paroxysmal nocturnal dyspnea
• Shortness of breath
• Wheezing

New York Heart Association Criteria (NYHA)

The following criteria are often used to gauge the severity of heart failure:

• NYHA I: No symptoms with ordinary activity.

• NYHA II: Slight limitation of physical activity. Comfortable at rest, but ordinary physical activity results in fatigue, palpitation, dyspnea, or angina.

• NYHA III: Marked limitation of physical activity. Comfortable at rest, but less than ordinary physical activity results in fatigue, palpitation, dyspnea, or anginal pain.

• NYHA IV: Unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency present at rest.
