Abstract

    

Introduction

Heart failure with preserved ejection fraction  is an increasingly recognized and important condition that poses a significant challenge to the cardiovascular community. Unlike Heart Failure with Reduced Ejection Fraction (HFrEF), where the heart’s pumping ability is compromised, is characterized by a normal or near-normal ejection fraction, yet patients still experience symptoms of heart failure. This article will explore the key aspects of , including its pathophysiology, risk factors, diagnostic challenges, and potential treatment strategies. , also known as diastolic heart failure, occurs when the heart's left ventricle becomes stiff and cannot relax properly between beats. This impairment in relaxation leads to increased pressure within the heart, which in turn causes fluid to back up into the lungs and other parts of the body, resulting in the typical symptoms of heart failure, such as shortness of breath, fatigue, and fluid retention. Despite these symptoms, the heart's ability to pump blood its ejection fraction remains relatively normal. Unlike, where the heart's muscle is weakened and its pumping ability is reduced, is primarily a disorder of the heart's filling and relaxation, leading to diastolic dysfunction. This makes more challenging to diagnose and treat is becoming more prevalent, especially as the population ages. It is estimated that approximately half of all heart failure cases [1,2].

The condition is more commonly seen in older adults, with a higher incidence in women, particularly those with obesity, hypertension, and diabetes.  is also associated with increased morbidity and mortality, making it an urgent public health concern. The aging population, along with rising rates of metabolic and cardiovascular diseases, contributes to the growing burden. It is expected that the prevalence of will continue to rise in the coming decades, adding to the challenge faced by healthcare systems worldwide.  is associated with a range of risk factors, many of which overlap with those for other cardiovascular diseases. Chronic high blood pressure is a major cause of Left Ventricular Hypertrophy (LVH), which increases the stiffness of the heart muscle and impairs its ability to relax. Excess body weight leads to increased cardiac workload and inflammatory changes that affect the heart's structure and function. The metabolic abnormalities associated with diabetes contribute to myocardial fibrosis and impaired ventricular relaxation. The natural aging process leads to stiffening of the heart muscle, making it more prone to developing diastolic dysfunction. Kidney dysfunction is often seen in conjunction with heart failure and contributes to the pathophysiology of. The underlying mechanisms of are complex and multifactorial. [3,4].

Increased fibrosis and thickening of the heart muscle lead to reduced compliance, impairing the heart's ability to fill properly during diastole. Abnormal blood vessel function can increase vascular stiffness and contribute to poor perfusion of the heart. Chronic inflammation and oxidative damage in the myocardium contribute to the progression of diastolic dysfunction. Impaired regulation of the autonomic nervous system can exacerbate heart failure symptoms and worsen cardiac performance. The diagnosis of is often difficult due to the absence of specific biomarkers and the fact that ejection fraction is normal. A comprehensive diagnostic approach is necessary to rule out other causes of symptoms and confirm the diagnosis of. Physicians evaluate the patient’s medical history, including risk factors such as hypertension, diabetes, and obesity, as well as symptoms like breathlessness and fatigue. This imaging technique is essential in assessing heart structure and function. While ejection fraction is preserved, echocardiography can reveal signs of diastolic dysfunction, such as impaired relaxation and increased left ventricular filling pressures. Elevated levels of natriuretic peptides, such as BNP or NT-proBNP, can indicate heart failure, but they are not specific to and may be normal in early stages. This technique provides detailed images of heart tissue and can detect myocardial fibrosis, which is a hallmark of. This invasive procedure may be necessary to measure diastolic pressures and confirm the diagnosis. The diagnostic challenge is compounded by the fact that can mimic other conditions such as Chronic Obstructive Pulmonary Disease (COPD) and obesity-related dyspnoea. Therefore, accurate diagnosis often requires a thorough and multifaceted approach. [5,6].

Currently, there are no specific treatments approved for and management primarily focuses on alleviating symptoms and improving quality of life. Controlling hypertension, diabetes, and obesity is critical in preventing the progression of Blood pressure management with agents such as ACE inhibitors, Angiotensin Receptor Blockers (ARBs), and mineralocorticoid receptor antagonists is essential.  These medications are used to manage fluid retention and relieve symptoms of congestion, such as swelling and shortness of breath. Regular physical activity can improve exercise tolerance and quality of life in patients with. Weight loss and dietary changes are also beneficial. Although no drug is specifically approved for recent studies have investigated the potential role of drugs that target inflammation, fibrosis, and myocardial relaxation. Drugs such as sodium-glucose cotransporter 2 (SGLT2) inhibitors have shown promise in improving outcomes in patients by reducing hospitalizations and improving heart function [7,8].

In selected patients, device-based therapies such as Cardiac Resynchronization Therapy (CRT) may be considered, though their benefits in are less clear compared. Despite these treatment options, the prognosis for remains poor, particularly as it progresses. The lack of effective therapies targeting the underlying mechanisms of the disease underscores the urgent need for continued research. Ongoing research is focused on better understanding the pathophysiology of developing more targeted treatments, and improving diagnostic techniques. Advances in molecular biology, genomics, and imaging may lead to the identification of specific biomarkers and novel therapeutic targets for additionally, large-scale clinical trials are needed to determine the efficacy of various pharmacologic agents and lifestyle interventions in improving outcomes for patients. As the burden of continues to grow, it is crucial for healthcare providers to remain vigilant in recognizing the condition and addressing its complex management needs. With continued research and innovation, there is hope that more effective treatments will emerge, improving the quality of life and prognosis for patients with this challenging condition. [9,10].

Conclusion

Heart failure with preserved ejection fraction is a growing concern in cardiovascular medicine, particularly as the global population ages and the prevalence of risk factors like hypertension and obesity increases. While significant strides have been made in understanding the disease, it remains difficult to diagnose and treat effectively. A comprehensive, multidisciplinary approach to managing focused on symptom relief, risk factor management, and ongoing research holds the key to improving outcomes for patients affected by this condition
