Chronic Diastolic (Congestive) Heart Failure: Understanding the Causes and Symptoms

Chronic diastolic heart failure, also known as congestive heart failure, is a condition that affects the heart's ability to pump blood efficiently. Unlike systolic heart failure, which occurs when the heart's pumping ability weakens, diastolic heart failure is characterized by a stiffening or thickening of the heart muscle, making it difficult for the heart to relax and fill with enough blood.

Causes:

1. Hypertension: High blood pressure is a leading cause of diastolic heart failure. Prolonged high blood pressure can cause the heart muscle to become stiff and less compliant, impairing its ability to relax during the diastolic phase.
2. Age: As we age, our heart muscle naturally loses some flexibility, increasing the risk of diastolic heart failure.
3. Obesity: Excessive weight gain causes increased strain on the heart, leading to changes in its structure and function over time.
4. Coronary Artery Disease: The buildup of plaque in the arteries can reduce blood flow to the heart, leading to diastolic dysfunction.
5. Valvular Heart Disease: Conditions such as aortic stenosis or mitral valve regurgitation can impair the heart's ability to relax and fill properly.

Symptoms:

• Shortness of breath, especially during physical activity or when lying down
• Fatigue and weakness
• Swelling in the legs, ankles, and feet
• Difficulty sleeping due to coughing or wheezing
• Reduced ability to exercise

Diagnosing chronic diastolic heart failure involves a comprehensive evaluation of symptoms, medical history, physical examination, and diagnostic tests such as echocardiography, electrocardiogram (ECG), or stress testing.

Managing chronic diastolic heart failure focuses on addressing underlying causes and relieving symptoms. Lifestyle modifications such as maintaining a healthy weight, adopting a heart-healthy diet, and regular exercise can help improve heart function. Medications may be prescribed to control blood pressure, reduce fluid retention, or manage other underlying conditions. In severe cases, medical procedures or surgery may be necessary to treat specific complications.

In conclusion, chronic diastolic heart failure is a condition characterized by the heart's inability to relax and fill properly. It is caused by various factors such as hypertension, aging, obesity, coronary artery disease, and valvular heart disease. Recognizing the symptoms and seeking
