Diastolic heart failure, also known as heart failure with preserved ejection fraction (HFpEF), is a condition where the heart’s ability to fill with blood during the diastolic phase (when the heart relaxes between beats) is impaired. Unlike systolic heart failure, where the heart’s pumping ability is weakened, diastolic heart failure involves issues with the heart’s filling phase.
This condition can cause symptoms such as shortness of breath, fatigue, and fluid retention.
Many people with diastolic heart failure wonder about their life expectancy and how this condition will affect their overall health. The prognosis for individuals with diastolic heart failure is influenced by a variety of factors, including age, severity of the condition, the presence of other medical conditions, and the management of the disease.
In this article, we will explore the life expectancy of someone with diastolic heart failure, factors that influence it, and the steps one can take to improve quality of life and potentially extend lifespan.
Understanding Diastolic Heart Failure
Diastolic heart failure is a complex condition in which the heart muscle becomes stiff and less able to relax. This stiffness affects the ability of the left ventricle to properly fill with blood. As a result, the heart has difficulty receiving enough blood from the lungs, which leads to less oxygenated blood being pumped throughout the body. The primary symptom of diastolic heart failure is shortness of breath, especially during physical exertion or at night.
The cause of diastolic heart failure is often linked to conditions like high blood pressure (hypertension), obesity, diabetes, and aging. Over time, these conditions contribute to changes in the structure and function of the heart, particularly the left ventricle.
In contrast to systolic heart failure, which affects the heart’s pumping strength, diastolic heart failure involves the filling phase. Despite the heart’s ability to pump blood effectively (preserved ejection fraction), the reduced ability to fill with blood can lead to fluid buildup in the lungs and other areas of the body.
Life Expectancy in Diastolic Heart Failure
The life expectancy of someone with diastolic heart failure can vary significantly based on several factors. It is important to understand that life expectancy is not determined by the heart failure condition alone, but by a combination of factors including:
Age: Older individuals are more likely to develop diastolic heart failure, and age can affect overall life expectancy. Older adults may have other underlying health conditions that can influence their prognosis.
Comorbidities: The presence of other medical conditions such as diabetes, hypertension, or kidney disease can impact life expectancy. These conditions can worsen heart failure or complicate its treatment.
Severity of Heart Failure: The degree of stiffness in the heart muscle and the extent of the heart’s impaired filling can play a role in determining life expectancy. More severe heart failure typically leads to a worse prognosis.
Response to Treatment: How well an individual responds to treatment also plays a crucial role in life expectancy. Effective management of risk factors like hypertension, diabetes, and obesity can help slow the progression of diastolic heart failure and improve survival rates.
How Diastolic Heart Failure Affects the Heart and the Body
In diastolic heart failure, the left ventricle becomes stiffer and less able to relax after contracting. As a result, the heart struggles to fill with blood, leading to lower blood volume being pumped out to the body with each beat. This reduced blood flow can cause a number of symptoms:
Shortness of breath: This is one of the hallmark symptoms, particularly during physical activity or even at rest in severe cases.
Fatigue: The body doesn’t receive enough oxygenated blood, leading to feelings of tiredness and decreased energy levels.
Fluid retention: When the heart can’t pump efficiently, blood backs up into the lungs and other parts of the body, causing swelling in the legs, ankles, and abdomen.
Increased heart rate: The heart may compensate for its reduced filling capacity by beating faster, which can lead to palpitations and further stress on the heart.
Despite these symptoms, individuals with diastolic heart failure often maintain a relatively preserved ejection fraction, meaning the percentage of blood pumped out of the heart with each beat remains normal or near normal. This differentiates diastolic heart failure from systolic heart failure, where the pumping ability is compromised.
Factors Influencing Life Expectancy in Diastolic Heart Failure
Several factors can influence the life expectancy of someone with diastolic heart failure. These factors include:
1. Age and Gender
Older adults, particularly those over the age of 65, are more likely to develop diastolic heart failure due to the natural aging process, which causes changes in heart tissue. Women tend to have a higher incidence of diastolic heart failure, which is partly due to hormonal changes after menopause that affect heart health.
2. Hypertension
High blood pressure is the leading cause of diastolic heart failure. Chronic hypertension can lead to the thickening and stiffening of the heart muscle, which contributes to impaired filling during diastole. Managing blood pressure through lifestyle changes and medication is crucial for improving outcomes.
3. Obesity
Obesity is another significant risk factor for diastolic heart failure. Excess weight places additional strain on the heart and can lead to inflammation, insulin resistance, and other metabolic disturbances that exacerbate heart failure.
4. Comorbid Conditions
The presence of other conditions such as diabetes, chronic kidney disease, or coronary artery disease can worsen the prognosis of someone with diastolic heart failure. These comorbidities contribute to the strain on the heart and increase the likelihood of complications.
5. Treatment and Management
Effective treatment of diastolic heart failure can improve life expectancy. Treatment typically includes managing the underlying conditions that contribute to heart failure, such as hypertension and diabetes. Medications like ACE inhibitors, beta-blockers, and diuretics may be used to help manage symptoms and prevent fluid retention. Additionally, lifestyle modifications such as weight loss, regular exercise, and a heart-healthy diet can help improve outcomes.
6. Early Diagnosis and Monitoring
Early detection and management of diastolic heart failure are key to improving life expectancy. Regular monitoring through medical check-ups, blood tests, and imaging studies can help identify changes in heart function and allow for timely interventions.
Prognosis And Survival Rates
Studies have shown that the survival rates for individuals with diastolic heart failure are generally better than those with systolic heart failure, although they still have a higher risk of complications. One study found that individuals with heart failure and preserved ejection fraction (HFpEF) had a 5-year survival rate of about 60-70%. This rate is comparable to other chronic conditions, such as diabetes, where long-term management is essential.
It is also important to note that while diastolic heart failure may be less immediately life-threatening than systolic heart failure, it can still lead to significant declines in quality of life due to the chronic symptoms and the potential for progression to more severe heart failure. Hospitalization rates for individuals with HFpEF tend to be higher, mainly due to complications like fluid retention and difficulty managing comorbidities.
Improving Life Expectancy in Diastolic Heart Failure
While diastolic heart failure is a chronic condition that requires lifelong management, several strategies can help improve both quality of life and life expectancy:
Manage Underlying Conditions: Controlling hypertension, diabetes, and obesity can significantly reduce the burden on the heart and slow the progression of diastolic heart failure.
Adopt a Heart-Healthy Lifestyle: Regular exercise, a balanced diet, and weight management can help improve overall heart function and prevent the worsening of symptoms.
Medication: Medications to control blood pressure, reduce fluid retention, and improve heart function can help manage symptoms and improve survival rates.
Monitor Symptoms: Regular medical check-ups and monitoring of heart function are important for detecting any changes in condition and adjusting treatment as needed.
Conclusion
The life expectancy of someone with diastolic heart failure can vary based on several factors, including age, comorbid conditions, and how effectively the condition is managed. While diastolic heart failure can lead to significant symptoms and complications, with proper treatment and lifestyle changes, individuals can live longer, healthier lives. It is important for people with diastolic heart failure to work closely with their healthcare providers to develop a comprehensive plan for managing the condition and improving their prognosis.
