Heart failure with preserved ejection fraction (HFpEF) is a type of heart failure where the heart muscle contracts normally, but the heart does not relax as it should, leading to problems with filling the heart with blood. Unlike the more common type of heart failure (heart failure with reduced ejection fraction, HFrEF), HFpEF is harder to detect and often more challenging to manage. It is also becoming increasingly clear that women are more likely to develop HFpEF, and they tend to suffer from it more severely. In this article, we will explore why this is the case, discuss the contributing factors, and offer insights on how this condition can be managed effectively.

Gender Differences in Heart Failure and Why Women Are More Affected

Studies have shown that women are disproportionately affected by HFpEF compared to men. This gender difference is attributed to several factors, including hormonal influences, underlying cardiovascular conditions, and differences in how the heart and circulatory system function in men and women.

One significant factor is estrogen, a hormone that plays a crucial role in maintaining cardiovascular health. After menopause, the levels of estrogen drop significantly in women, which can lead to changes in the heart’s structure and function. This decline in estrogen is believed to contribute to the increased prevalence of HFpEF in postmenopausal women. Additionally, women tend to have smaller heart chambers and thicker heart walls, which may exacerbate the effects of HFpEF.

Another contributing factor is that women are more likely to have conditions like obesity, diabetes, and high blood pressure, all of which increase the risk of developing HFpEF. These conditions can also complicate the management and treatment of the condition, making it more challenging to address effectively.

Key Risk Factors for Women with HFpEF

Several risk factors contribute to the higher incidence of HFpEF in women. These include both lifestyle and medical factors, some of which are more prevalent in women than men:

• Obesity: Obesity is a major risk factor for HFpEF. Women are more likely than men to develop obesity-related cardiovascular issues, including heart failure. The accumulation of fat tissue, particularly around the abdomen, can lead to increased pressure on the heart, impairing its ability to function properly.
• Hypertension: High blood pressure is a leading cause of heart failure, and women are more likely to develop hypertension as they age. Chronic hypertension increases the risk of developing HFpEF by causing the heart muscle to thicken and stiffen, limiting its ability to relax and fill with blood.
• Diabetes: Diabetes, especially type 2 diabetes, is another risk factor that is more common in women. High blood sugar levels can damage blood vessels, including those that supply the heart, leading to an increased risk of HFpEF.
• Age and Menopause: The risk of developing HFpEF increases with age, particularly in women who have gone through menopause. The hormonal changes during menopause contribute to the development of this condition.

Symptoms and Diagnosis of HFpEF in Women

The symptoms of HFpEF can be subtle and may be mistaken for other health issues, making diagnosis challenging. Women with HFpEF often experience the following symptoms:

• Shortness of Breath: One of the most common symptoms, especially during physical exertion or when lying flat.
• Fatigue: Women with HFpEF may feel constantly tired, even after getting enough rest.
• Swelling (Edema): Swelling in the legs, ankles, or abdomen is another sign, as the heart struggles to pump blood effectively.
• Chest Discomfort: Some women report chest discomfort, which can be misinterpreted as anxiety or other non-cardiac issues.

To diagnose HFpEF, doctors typically rely on a combination of physical exams, medical history, blood tests, and imaging studies like echocardiograms. One of the most important diagnostic markers for HFpEF is preserved ejection fraction, meaning the heart pumps blood normally but has difficulty filling properly.

Treatment and Management of HFpEF in Women

While there is no cure for HFpEF, there are several ways to manage and treat the condition to improve quality of life. Treatment for HFpEF focuses on controlling symptoms and preventing the condition from worsening. Common treatment strategies include:

• Medications: Medications to control blood pressure, reduce fluid retention, and address underlying conditions like diabetes are essential. Commonly prescribed drugs include ACE inhibitors, beta-blockers, and diuretics. However, it’s important to note that while medications help manage symptoms, they do not reverse the underlying condition.
• Lifestyle Changes: Lifestyle modifications such as regular exercise, a balanced diet, weight management, and quitting smoking can significantly improve symptoms and reduce the risk of complications.
• Managing Underlying Conditions: Effectively managing risk factors such as hypertension, diabetes, and obesity is key to preventing the progression of HFpEF. Women with these conditions should work closely with their healthcare providers to keep them under control.
• Regular Monitoring: Regular follow-ups with healthcare providers are necessary to monitor heart function and adjust treatment as needed. Routine tests such as echocardiograms and blood pressure monitoring are vital for managing HFpEF.

While HFpEF can be challenging to manage, with the right treatment and lifestyle changes, women can live full, active lives. For further guidance on managing heart failure and related conditions, visit HeartCare Hub, where you'll find expert advice, products, and services tailored to your needs.
