Congestive heart failure (CHF) is a serious medical condition that affects the heart’s ability to pump blood. It is a common condition in Singapore, affecting thousands of people every year. CHF occurs when the heart muscle becomes weak or damaged, making it difficult for the heart to pump blood effectively. This can lead to a buildup of fluid in the lungs, liver, and other organs, causing symptoms such as shortness of breath, fatigue, and swelling in the legs and ankles.
Understanding CHF is crucial for effective management and prevention of complications. While the condition cannot be cured, it can be managed with proper treatment and lifestyle changes. Risk factors for CHF include high blood pressure, coronary artery disease, diabetes, and obesity. Early diagnosis and treatment are important for improving outcomes and preventing complications.
The management of CHF involves a multidisciplinary approach, including medication, lifestyle changes, and regular monitoring. In Singapore, there are several programmes and guidelines available to help healthcare professionals manage patients with CHF. With proper management, many people with CHF can lead full and active lives.

Understanding Congestive Heart Failure
Definition and Prevalence in Singapore
Congestive heart failure (CHF) is a chronic and progressive condition that occurs when the heart is unable to pump enough blood to meet the body’s demands. In Singapore, CHF is a significant health concern, with an estimated prevalence of 2.7% among adults aged 18 to 69 years, and 11.3% among those aged 70 years and above. CHF is the leading cause of hospitalisation among adults aged 60 years and above in Singapore.
Anatomy of the Heart
The heart is a vital organ that pumps blood throughout the body. It is composed of four chambers – the right atrium, right ventricle, left atrium, and left ventricle – and four valves – the tricuspid valve, pulmonary valve, mitral valve, and aortic valve. The heart is also supplied by a network of arteries that provide oxygen and nutrients to the heart muscle.
Pathophysiology
CHF can occur due to various underlying conditions that affect the heart’s ability to pump blood effectively. Some common causes of CHF include coronary artery disease, hypertension, heart valve disease, and cardiomyopathy. When the heart is unable to pump blood effectively, fluid can build up in the lungs and other parts of the body, leading to symptoms such as shortness of breath, fatigue, and swelling of the legs and ankles.
In summary, CHF is a chronic and progressive condition that affects the heart’s ability to pump blood effectively. It is a significant health concern in Singapore, particularly among older adults. Understanding the anatomy of the heart and the pathophysiology of CHF is crucial in managing this condition effectively. It is advisable to seek medical advice if one experiences any symptoms of CHF to receive appropriate treatment.

Causes and Risk Factors
Heart failure is a condition where the heart is unable to pump blood effectively, leading to a variety of symptoms. There are several causes and risk factors that can contribute to the development of heart failure.
Common Causes of Heart Failure
The most common cause of heart failure is coronary artery disease, which occurs when the arteries that supply blood to the heart become narrowed or blocked. This can lead to a heart attack, which can damage the heart muscle and reduce its ability to pump blood effectively. Other causes of heart failure include cardiomyopathy, a disease of the heart muscle, and congenital heart disease, which is a condition that is present at birth.
Lifestyle and Environmental Risk Factors
Several lifestyle and environmental factors can increase the risk of developing heart failure. These include smoking, which increases the risk of heart disease and can damage the heart muscle over time. Alcohol consumption can also contribute to the development of heart failure, as excessive drinking can lead to high blood pressure and other heart problems.
Obesity is another risk factor for heart failure, as it can lead to high blood pressure, diabetes mellitus, and other conditions that can damage the heart muscle. Diabetes mellitus itself is also a risk factor for heart failure, as it can lead to damage to the blood vessels and nerves that supply the heart.
Other risk factors for heart failure include thyroid disease, anaemia, and stress. A diet high in salt can also increase the risk of developing heart failure, as it can lead to high blood pressure and other heart problems.
It is important to note that some risk factors for heart failure cannot be controlled, such as age, gender, and family history. However, making lifestyle changes and managing conditions such as high blood pressure and diabetes mellitus can help to reduce the risk of developing heart failure.

Diagnosis and Management
Clinical Diagnosis
Diagnosing congestive heart failure (CHF) involves a comprehensive evaluation of the patient’s medical history, physical examination, echocardiography, and other diagnostic tests. The physical examination may reveal signs of fluid accumulation in the lungs, legs, and abdomen. Echocardiography is a diagnostic test that provides information about the heart’s size, shape, and function, including the ejection fraction.
Treatment Options
The treatment of CHF typically involves a combination of medications, lifestyle modifications, and, in some cases, surgery. Medications such as ACE inhibitors, beta-blockers, and diuretics may be prescribed to help manage symptoms and improve the heart’s function. Lifestyle modifications such as dietary changes and exercise are also important in the management of CHF.
Living with Heart Failure
Living with CHF can be challenging, but with proper management, patients can improve their quality of life and prolong survival. Patients with CHF should work closely with their healthcare providers to manage their symptoms and make necessary lifestyle changes. A structured outpatient programme, which may include a specialist nurse clinician and phone consultations, can help patients manage their condition and improve their quality of life.
In summary, CHF is a serious condition that requires proper diagnosis and management. The Department of Cardiology, working with a multidisciplinary team, can help patients manage their condition and improve their quality of life. It is important for patients to work closely with their healthcare providers to manage their symptoms and make necessary lifestyle changes.
Frequently Asked Questions
