Description

Heart Failure (HF) is a complex syndrome characterized by the heart’s inability to pump blood effectively, leading to impaired tissue perfusion and fluid retention. Traditionally, heart failure was classified into two main categories based on Left Ventricular Ejection Fraction (LVEF): Heart Failure with reduced Ejection Fraction (HFrEF) and Heart Failure with preserved Ejection Fraction (HFpEF). While HFrEF has been the focus of much study and therapeutic development over the past few decades, HFpEF is emerging as a growing concern in the field of cardiovascular medicine due to its increasing prevalence and the challenges it presents in terms of diagnosis and treatment. Heart failure with preserved ejection fraction is a form of heart failure in which the heart muscle contracts normally, but the ventricles do not relax properly during diastole, impairing the heart’s ability to fill with blood. As a result, although the Ejection Fraction (EF) is preserved typically greater than 50% the heart is unable to meet the body’s demands for blood and oxygen, leading to symptoms such as shortness of breath, fatigue and fluid retention. HFpEF is also referred to as diastolic heart failure, as the primary issue lies in the diastolic phase of the cardiac cycle, during which the heart muscle relaxes and fills with blood.

HFpEF has become an increasingly common diagnosis, especially among older adults. It is estimated that HFpEF accounts for 50%-60% of all heart failure cases and its prevalence continues to rise, mirroring the aging population and the increasing burden of chronic diseases such as hypertension, diabetes and obesity. HFpEF predominantly affects women, particularly those over the age of 60 and is often associated with a range of comorbid conditions, including obesity, hypertension, diabetes, atrial fibrillation and chronic kidney disease. In fact, hypertension is considered one of the most important risk factors for the development of HFpEF, as it leads to Left Ventricular Hypertrophy (LVH) and increased ventricular stiffness, both of which contribute to impaired diastolic function.

The clinical presentation of HFpEF is often subtle and can overlap with other conditions, making diagnosis challenging. Patients typically present with symptoms of heart failure, such as dyspnea on exertion, fatigue and peripheral edema, but without the reduced ejection fraction seen in HFrEF. These symptoms are due to the impaired filling of the left ventricle, which leads to elevated pressures in the left atrium and pulmonary vasculature, causing pulmonary congestion and systemic fluid retention. Patients with HFpEF may also experience other symptoms such as exercise intolerance and decreased ability to perform daily activities. Because the ejection fraction is preserved, patients with HFpEF often have a relatively normal Electrocardiogram (ECG) and echocardiogram, making it difficult to distinguish from other types of heart failure or respiratory conditions. The presence of comorbidities such as atrial fibrillation, chronic kidney disease and diabetes further complicates the clinical picture and management of these patients. The diagnosis of HFpEF requires a combination of clinical assessment, imaging studies and laboratory tests. A thorough history and physical examination are crucial to identify symptoms consistent with heart failure and to rule out other potential causes of symptoms. Although the ejection fraction is preserved in HFpEF, echocardiography is still an important diagnostic tool. Doppler studies may reveal elevated left atrial pressures and abnormal diastolic filling patterns, which are characteristic of HFpEF.

Conclusion

Heart failure with preserved ejection fraction represents a growing and increasingly important aspect of cardiovascular medicine. With its complex pathophysiology, challenging diagnosis and lack of diseasemodifying treatments, HFpEF poses significant difficulties for clinicians and studiers alike. However, as the prevalence of HFpEF continues to rise, there is a growing need for better diagnostic tools and more effective therapies. Through improved management of comorbidities, symptom control and ongoing study into novel treatments, it is hoped that the prognosis for patients with HFpEF will continue to improve, ultimately enhancing their quality of life and reducing the burden of heart failure worldwide.
