Heart Failure Clinic

The Heart Failure Clinic at Bangkok Heart Hospital focuses on the diagnosis, management, and treatment of heart failure. Heart failure is a syndrome that occurs when the heart is unable to pump enough blood to meet the body's needs. It can be categorized into systolic heart failure (weakened pumping chamber) and diastolic heart failure (abnormal relaxation of the heart muscle), or a combination of both.

Proper management of heart failure, including medications and lifestyle changes, can improve the signs and symptoms of the condition and help patients live longer. Lifestyle changes such as exercise, reducing salt intake, managing stress, maintaining a healthy weight, and not smoking can improve the quality of life for heart failure patients. The support of family and friends who understand the condition is also important.

The pathophysiology of heart failure involves abnormalities in the systolic and diastolic functions of the heart, leading to changes in the circulatory and neurohormonal systems. This results in symptoms and signs of heart failure, including fluid retention and increased ventricular pressures.

The ejection fraction (EF) is a measurement of the efficiency of the heart's pumping chamber (left ventricle). Systolic heart failure is characterized by an EF less than 40% (Heart Failure with reduced Ejection Fraction - HFrEF), while diastolic heart failure has an EF greater than 40% (Heart Failure with preserved Ejection Fraction - HFpEF). Ejection fraction can be measured through various imaging techniques such as echocardiogram, radioisotope study, angiogram, CT scan, or MRI scan.

Heart failure can be classified into different types, including left heart failure, right heart failure, acute heart failure (requiring admission), and chronic heart failure. Various underlying heart conditions or diseases can lead to heart failure, such as coronary artery disease, hypertension, cardiomyopathy, heart valve disease, arrhythmias, infections, immunologic processes, and certain substances like heavy alcohol consumption or certain drugs.

The diagnosis of heart failure involves a thorough medical history, physical examination, laboratory tests, and imaging studies such as electrocardiogram (ECG or EKG), chest x-ray, and echocardiogram. Treatment for heart failure includes lifestyle changes, medication compliance, and various medications such as neurohormonal antagonists (ACE inhibitors, ARBs, beta-blockers, aldosterone antagonists), diuretics, inotropes, and other medications for associated conditions. Devices treatment such as cardiac resynchronization therapy (CRT), internal cardioverter defibrillator (ICD), or left ventricular assist devices (LVADs) may be utilized, and surgery such as coronary artery bypass graft (CABG), valve replacement, or cardiac transplantation may be considered in specific cases.

The Heart Failure Clinic at Bangkok Heart Hospital provides consultation and extensive education for heart failure patients and their families. The clinic promotes evidence-based and uniform practice, offers transtelephonic follow-up, has an advanced in-patient to out-patient transition program, and employs a multidisciplinary management approach. Data collection and future clinical research are also conducted at the clinic.

The Heart Failure Program at Bangkok Heart Hospital has been certified by Joint Commission International (JCI) since 2008, indicating the high international standard of care provided. The program has achieved excellent performance measures, including high utilization of guideline-directed medications, extensive patient education, smoking cessation counseling, appropriate prescription of anticoagulation in atrial fibrillation, appropriate discussion of device therapy, and a low 30-day readmission rate.

Overall, the Heart Failure Clinic at Bangkok Heart Hospital is dedicated to providing comprehensive care for heart failure patients, improving outcomes, and enhancing their quality of life.
