Congestive cardiac failure (CCF) is an important topic in Clinical Medicine, Nursing, Pharmacy and other healthcare training programmes. Understanding its causes, pathophysiology, clinical features, investigations and management helps students develop the clinical reasoning skills required for examinations and clinical practice.

This comprehensive guide covers the essential principles of heart failure, with examples relevant to healthcare practice in Kenya.

Learning Objectives

By the end of this article, you should be able to:

Define congestive cardiac failure.
Explain the causes and classification of heart failure.
Describe the pathophysiology of CCF.
Identify its major symptoms and clinical signs.
Select appropriate diagnostic investigations.
Explain the principles of acute and chronic management.
Recognise complications and emergency features.
Answer examination questions on CCF.

1. Definition of Congestive Cardiac Failure

Congestive cardiac failure is a clinical syndrome in which structural or functional abnormalities of the heart result in impaired ventricular filling, impaired pumping, or both. This may lead to inadequate tissue perfusion and increased pressures within the heart, causing fluid congestion in the lungs or other parts of the body.

The modern term heart failure is widely used because congestion may not be present in every patient.

Heart failure is not the same as cardiac arrest. In heart failure, the heart continues to function but cannot meet the body's needs adequately without compensatory changes. Cardiac arrest occurs when effective circulation suddenly stops.

2. Anatomy and Physiology of the Heart

The heart is a muscular organ that pumps blood through the pulmonary and systemic circulations.

It consists of four chambers:

Right atrium: receives deoxygenated blood from the body.
Right ventricle: pumps blood to the lungs.
Left atrium: receives oxygenated blood from the lungs.
Left ventricle: pumps oxygenated blood to the systemic circulation.

The four major valves are the tricuspid, pulmonary, mitral and aortic valves. They help maintain one-way blood flow.

Cardiac output

Cardiac output is the volume of blood pumped by the heart per minute.

Cardiac output = Stroke volume × Heart rate

Stroke volume is the amount of blood ejected by a ventricle during one heartbeat, while heart rate is the number of heartbeats per minute.

Three important factors influence cardiac performance:

Preload: the degree of ventricular filling and myocardial stretch before contraction.
Afterload: the resistance against which the ventricle pumps.
Contractility: the ability of the heart muscle to contract.

When the heart muscle is damaged or the ventricles cannot relax and fill properly, cardiac function may deteriorate. Pressure can rise behind the affected ventricle, causing congestion.

3. Classification of CCF

A. Classification according to the affected side

Type	Main mechanism	Typical clinical features
Left-sided heart failure	Raised left-sided filling pressures and/or reduced systemic output	Breathlessness, orthopnoea, lung crackles
Right-sided heart failure	Raised systemic venous pressure	Leg oedema, raised JVP, hepatomegaly, ascites
Biventricular heart failure	Both ventricles are affected	Pulmonary and systemic congestion

JVP means jugular venous pressure.

Left-sided heart failure may eventually contribute to right-sided failure because persistent pulmonary venous hypertension can increase pressure in the pulmonary circulation.

B. Classification according to onset

Acute heart failure: New or rapidly worsening heart failure that may require emergency assessment and hospital treatment.

Chronic heart failure: A persistent condition requiring long-term treatment, monitoring and lifestyle support.

Acute decompensated heart failure: Sudden or progressive deterioration in a person with established or previously unrecognised heart failure.

C. Classification according to left ventricular ejection fraction

Ejection fraction (EF) is the percentage of blood in the left ventricle that is ejected during each contraction.

Category	Left ventricular ejection fraction
Heart failure with reduced EF (HFrEF)	40% or less
Heart failure with mildly reduced EF (HFmrEF)	41–49%
Heart failure with preserved EF (HFpEF)	50% or more

Heart failure with preserved EF can occur despite a relatively normal ejection fraction because the ventricle may be stiff and unable to relax or fill normally. Diagnosis requires the appropriate clinical findings and supporting evidence, not EF alone.

D. New York Heart Association (NYHA) functional classification

Class I: Ordinary physical activity does not cause undue symptoms.
Class II: Slight limitation of physical activity; ordinary activity causes symptoms.
Class III: Marked limitation; less-than-ordinary activity causes symptoms.
Class IV: Symptoms occur at rest or with any physical activity.

This classification helps describe functional limitation and monitor changes over time.

4. Causes and Risk Factors of CCF

Heart failure may result from conditions that damage the heart muscle, increase the workload of the heart, or interfere with normal filling.

Common causes

1. Hypertension

Long-standing high blood pressure increases the workload of the left ventricle. The ventricular muscle may thicken and later become stiff or weakened.

2. Ischaemic heart disease

Reduced blood supply to the myocardium can impair cardiac function. A myocardial infarction may permanently damage part of the heart muscle.

3. Valvular heart disease

Diseases affecting the mitral, aortic or other valves may cause stenosis or regurgitation, increasing pressure or volume overload.

4. Cardiomyopathies

These diseases affect the structure or function of the heart muscle. Examples include dilated and hypertrophic cardiomyopathy.

5. Rheumatic heart disease

Rheumatic damage to the heart valves can cause progressive cardiac dysfunction.

6. Arrhythmias

Persistent tachyarrhythmias or severe bradyarrhythmias can reduce cardiac output. Some prolonged arrhythmias can also cause cardiomyopathy.

7. Other causes

Congenital heart disease.
Severe or chronic anaemia.
Diabetes mellitus.
Chronic kidney disease.
Thyroid disorders.
Pulmonary hypertension.
Chronic lung disease.
Myocarditis and other myocardial infections or inflammatory conditions.
Peripartum cardiomyopathy.

Precipitating factors

A patient with established heart failure may suddenly deteriorate because of:

Pneumonia or another infection.
Uncontrolled hypertension.
Acute coronary syndrome.
New or worsening arrhythmia.
Missed medication or interruption of treatment.
Excessive sodium intake.
Worsening renal function.
Pulmonary embolism.
Anaemia or other acute illness.

Examination point: The underlying cause explains why heart failure developed, while the precipitating factor explains why the patient's condition worsened at a particular time.

5. Pathophysiology of CCF

The pathophysiology of heart failure involves abnormalities in cardiac pumping or filling, neurohormonal responses, fluid retention and progressive changes in cardiac structure.

Step-by-step explanation

Initial cardiac problem: Hypertension, myocardial infarction, valve disease or another condition impairs cardiac function.
Reduced pumping or impaired filling: The ventricles may fail to eject blood adequately or may not relax and fill normally.
Reduced effective output and/or raised filling pressures: Tissue perfusion may decline, while pressure builds up behind the affected ventricle.
Sympathetic nervous system activation: Heart rate and vascular tone increase to maintain circulation.
RAAS activation: The renin–angiotensin–aldosterone system promotes vasoconstriction and sodium and water retention.
Fluid accumulation: Retained fluid and increased venous pressures contribute to pulmonary or peripheral congestion.
Cardiac remodelling: Persistent stress can cause ventricular dilation, hypertrophy and fibrosis.
Progressive deterioration: These compensatory mechanisms eventually increase the workload of the heart and may worsen heart failure.

Why does pulmonary congestion occur?

When left ventricular filling pressure rises, pressure is transmitted backwards to the left atrium and pulmonary veins. Fluid may move into the lung interstitium and, in severe cases, into the alveoli. This interferes with gas exchange and causes breathlessness.

Why does peripheral oedema occur?

Raised systemic venous pressure increases fluid movement from blood vessels into surrounding tissues. Sodium and water retention further contribute to swelling, particularly in dependent areas such as the ankles and legs.

6. Clinical Features of CCF

The clinical presentation depends on the severity of disease, the affected ventricle, the underlying cause and whether the patient is stable or acutely decompensated.

Symptoms

Dyspnoea: Breathlessness during activity or, in severe cases, at rest.

Orthopnoea: Breathlessness when lying flat, often relieved by sitting upright or using extra pillows.

Paroxysmal nocturnal dyspnoea: Episodes of breathlessness that awaken a patient from sleep.

Fatigue: Reduced exercise capacity resulting from impaired circulation, muscle changes and other contributing conditions.

Peripheral swelling: Swelling of the feet and ankles due to fluid accumulation.

Other symptoms: Nocturnal cough, abdominal distension, reduced appetite, early satiety and occasionally reduced urine output in severe illness.

Physical signs

Tachycardia.
Tachypnoea.
Elevated jugular venous pressure.
Bilateral pitting oedema.
Basal lung crackles.
Third heart sound (S3), particularly in some patients with reduced EF.
Tender or enlarged liver.
Ascites.
Displaced apex beat in some patients with ventricular enlargement.
Cool extremities, confusion or hypotension in severe low-output states.

Left-sided versus right-sided heart failure

Feature	Left-sided	Right-sided
Breathlessness	Common	May occur, especially with coexisting left-sided failure
Orthopnoea	Common	Less characteristic
Pulmonary crackles	May occur	Not a defining feature of isolated right-sided failure
Raised JVP	May occur	Common
Leg oedema	Possible	Common
Hepatomegaly and ascites	May occur in advanced disease	Common in significant systemic congestion

Clinical findings are not always textbook-perfect. No single symptom or physical sign confirms heart failure, and alternative diagnoses must be considered.

7. Investigations for CCF

Investigations help confirm the diagnosis, determine severity, identify the cause and guide treatment.

Investigation	Purpose
History and physical examination	Identify symptoms, signs, risk factors and precipitating causes
ECG	Detect arrhythmias, conduction abnormalities and evidence suggesting ischaemia or previous infarction
Chest X-ray	Assess pulmonary congestion, pleural effusions and cardiac enlargement
Echocardiography	Assess ventricular function, ejection fraction, chamber size, valves and other structural abnormalities
BNP or NT-proBNP	Support diagnosis, particularly when heart failure is suspected but uncertain
Full blood count	Identify anaemia and possible infection
Urea, creatinine and electrolytes	Assess renal function and identify abnormalities affecting treatment
Liver function tests	Assess possible hepatic congestion or other liver disease
Glucose and HbA1c	Identify diabetes or assess glycaemic control
Thyroid function tests	Investigate suspected thyroid-related contributors
Troponin	Assess possible myocardial injury when clinically indicated

Other tests, such as iron studies, investigations for pulmonary embolism or coronary assessment, may be indicated according to the clinical presentation.

Important examination points

Echocardiography is central to evaluating cardiac structure and function.

BNP and NT-proBNP are useful biomarkers, but interpretation depends on the clinical context. Levels may be influenced by age, renal function, obesity and other conditions.

Chest X-ray can support the diagnosis but may be normal in some patients with heart failure.

Differential diagnoses

Consider:

Pneumonia.
Chronic obstructive pulmonary disease.
Pulmonary embolism.
Chronic kidney disease with fluid overload.
Severe anaemia.
Liver disease with ascites.
Venous insufficiency.

8. Management of Congestive Cardiac Failure

Management aims to stabilise the patient, relieve congestion, treat the underlying cause, prevent hospital admissions and improve survival and quality of life.

Treatment must be individualised according to the patient's blood pressure, oxygenation, volume status, renal function, electrolyte levels, ejection fraction and other medical conditions.

A. Acute decompensated heart failure

Acute severe breathlessness or pulmonary oedema is a medical emergency.

Initial management includes:

Assess airway, breathing and circulation.
Check vital signs, oxygen saturation, mental status and signs of shock.
Position the patient upright if breathing is difficult and this is tolerated.
Provide oxygen if the patient is hypoxaemic; oxygen is not routinely necessary when oxygen saturation is normal.
Establish appropriate monitoring and arrange urgent transfer or admission when indicated.
Give intravenous loop diuretics for significant congestion under appropriate clinical supervision.
Consider non-invasive ventilation for selected patients with severe respiratory distress.
Investigate and treat precipitating causes, including infection, arrhythmia, uncontrolled hypertension or acute coronary syndrome.
Monitor urine output, renal function, electrolytes and response to treatment.

Vasodilators may be considered in selected patients with adequate blood pressure. Inotropes or vasopressors are reserved for selected patients with severe low-output states or shock and require close monitoring.

Do not delay emergency referral while waiting for every investigation to become available.

B. Chronic heart failure

Long-term management depends on the type of heart failure and the patient's clinical condition.

Four foundational medication classes for eligible patients with HFrEF

1. ARNI, ACE inhibitors or ARBs

These medicines reduce harmful effects of the renin–angiotensin system and help reduce disease progression. An angiotensin receptor–neprilysin inhibitor (ARNI) is preferred for many eligible patients when available and appropriate. An ACE inhibitor or ARB may be used according to the clinical circumstances.

Monitor blood pressure, renal function and potassium. ACE inhibitors and ARNIs must not be used together.

2. Evidence-based beta-blockers

Selected beta-blockers improve outcomes in HFrEF by reducing harmful sympathetic stimulation. They are generally started or increased when the patient is clinically stable, rather than during uncontrolled acute decompensation.

3. Mineralocorticoid receptor antagonists

Examples include spironolactone and eplerenone. They can improve outcomes in eligible patients but may increase potassium and affect renal function. Appropriate laboratory monitoring is essential.

4. SGLT2 inhibitors

Examples include dapagliflozin and empagliflozin. These drugs improve outcomes in eligible patients with HFrEF, including many who do not have diabetes. Suitability, contraindications, renal function and access must be considered.

These four classes are foundational therapies for HFrEF, but not every patient can take every class. Drug selection, initiation and dose adjustment require individual assessment. Recommendations for HFmrEF and HFpEF differ and depend on the patient's specific presentation. See the professional guidelines listed below.

Diuretics

Loop diuretics, such as furosemide, help relieve fluid congestion and improve symptoms. They are particularly useful when a patient has pulmonary or peripheral fluid overload.

They require appropriate monitoring of blood pressure, kidney function, urine output and electrolytes.

Important distinction: Diuretics relieve congestion, while the foundational HFrEF therapies target disease progression and clinical outcomes.

C. Non-pharmacological management

Explain the importance of taking prescribed medication consistently.
Encourage appropriate sodium intake according to clinical advice.
Individualise fluid restriction rather than applying the same limit to every patient.
Encourage daily weight monitoring when practical.
Advise patients to seek review for increasing swelling, worsening breathlessness or rapid unexplained weight gain.
Encourage appropriate physical activity and rehabilitation when clinically stable.
Support smoking cessation and avoidance of harmful alcohol use.
Address hypertension, diabetes, coronary disease and other contributing conditions.
Arrange regular follow-up and laboratory monitoring.
Refer selected patients for specialist assessment when advanced therapies or devices may be appropriate.

Patients should not stop prescribed medication or change doses without appropriate clinical advice.

D. Special considerations in Kenyan practice

In facilities with limited resources, early recognition, reliable clinical assessment, access to essential investigations, medication availability and timely referral are particularly important.

Use the Kenya National Guidelines for the Management of Cardiovascular Diseases and relevant Ministry of Health protocols to guide practice. Consider the patient's ability to obtain medicines, attend follow-up and complete laboratory monitoring.

9. Complications of CCF

Important complications include:

Acute pulmonary oedema.
Cardiogenic shock.
Cardiac arrhythmias.
Thromboembolic events.
Renal dysfunction.
Hepatic congestion.
Electrolyte disturbances.
Recurrent hospital admissions.
Reduced exercise capacity and quality of life.
Increased risk of death.

Early diagnosis, appropriate treatment and regular follow-up can reduce avoidable complications.

10. Clinical Officer and Nursing Responsibilities

Healthcare professionals play an important role in monitoring, patient education and recognising deterioration.

Assessment

Obtain a focused history of breathlessness, orthopnoea, swelling and exercise tolerance.
Ask about hypertension, diabetes, previous cardiac disease and current medicines.
Assess blood pressure, pulse, respiratory rate, oxygen saturation and temperature as indicated.
Examine for raised JVP, crackles, oedema and signs of poor perfusion.

Monitoring

Record vital signs and clinical changes accurately.
Monitor fluid intake and output when indicated.
Assess weight trends and oedema.
Monitor renal function and electrolytes during relevant treatment.
Watch for hypotension, worsening respiratory distress, confusion and reduced urine output.

Patient education

Explain the diagnosis in language the patient understands. Discuss medication adherence, appropriate dietary advice, warning signs, follow-up appointments and the importance of addressing the underlying cause.

Documentation

Record the patient's symptoms, examination findings, investigations, working diagnosis, treatment, response and referral plan.

11. Clinical Case Study

A 58-year-old man with a 12-year history of hypertension presents with progressive breathlessness over three weeks. He now sleeps using three pillows and has noticed bilateral ankle swelling. Examination reveals tachycardia, elevated JVP, bilateral basal crackles and pitting oedema. His blood pressure is 164/96 mmHg.

Questions

What is the most likely diagnosis?
Give five findings supporting your diagnosis.
List five appropriate investigations.
Explain the pathophysiology responsible for his symptoms.
Outline the immediate management priorities.
Describe the principles of long-term management.
List four possible complications.

Model answers

1. Most likely diagnosis: Heart failure with pulmonary and systemic congestion, possibly precipitated or worsened by uncontrolled hypertension. Echocardiography and further assessment are required to establish the phenotype and investigate the cause.

2. Supporting findings:

Progressive breathlessness.
Orthopnoea.
Bilateral ankle oedema.
Raised JVP.
Basal lung crackles.

3. Investigations:

ECG.
Echocardiography.
Chest X-ray.
BNP or NT-proBNP where available.
Full blood count, renal function and electrolytes.

Additional tests, including glucose, liver function and troponin when indicated, may be appropriate.

4. Pathophysiology: Hypertension increases ventricular workload and can lead to hypertrophy and impaired filling or contraction. Raised cardiac filling pressures contribute to pulmonary congestion, while systemic venous pressure and fluid retention contribute to peripheral oedema.

5. Immediate management: Assess respiratory status and circulation, monitor vital signs and oxygen saturation, evaluate the degree of congestion, provide oxygen if hypoxaemic, arrange urgent assessment or admission as appropriate, and treat congestion and the underlying precipitating factors under clinical supervision.

6. Long-term management: Confirm the diagnosis and ejection fraction, control hypertension, initiate suitable evidence-based treatment, monitor renal function and electrolytes, address cardiovascular risk factors, provide patient education and arrange follow-up.

7. Complications: Acute pulmonary oedema, arrhythmias, renal dysfunction and cardiogenic shock.
