Thekey difference收缩和舒张功能障碍之间is that systolic dysfunction is due to a weakened左心室心脏无法按照其应收缩的方式引起的心脏，而舒张功能障碍是由于心脏无法按照其应有的方式放松的左心室而引起的。

Systolic dysfunction is heart failure due to a weakened left ventricle of the heart due to its inability to contract the way it should. This is because the left ventricle has become bigger, and the heart cannot pump with enough force to push the blood throughout the body. The causes of systolic dysfunction includehigh blood pressure,冠状动脉疾病,心肌病, and heart valve problems. People with systolic dysfunction may have symptoms such as shortness of breath, tiredness, weakness, swelling in feet, ankles, legs, or abdomen, lasting cough or wheezing, fast and irregular heartbeats, dizziness, confusion, neediness to pee more at night, nausea, and lack of appetite.
Diastolic dysfunction can be diagnosed through physical examination, medical history, echocardiogram, blood tests, electrocardiogram, chest X-ray, ultrasound, exercise test, and heart catheterization. Furthermore, the treatments for diastolic dysfunction may include a healthy lifestyle (healthy weight, balanced diet that is low in salt, cardiovascular exercises), medications (water pills for edema, other medications to control high blood pressure, diabetes, other heart conditions like atrial fibrillation), implantation of left ventricular assist device (LVAD), and heart transplantation.
What are the Similarities Between Systolic and Diastolic Dysfunction?
- Systolic and diastolic dysfunction are two types of left ventricle heart failures.
- In both types of conditions, the left ventricle is unable to pump the required amount of blood throughout the body.
- They are treated through lifestyle changes, medications, and surgeries.
Systolic dysfunction is due to a weakened left ventricle of the heart caused by the inability of the heart to contract the way it should, while diastolic dysfunction is due to a stiffer left ventricle caused by the inability of the heart to relax the way it should. Thus, this is the key difference between systolic and diastolic dysfunction. Furthermore, the causes of systolic dysfunction include high blood pressure, coronary artery disease, cardiomyopathy, and heart valve problems. On the other hand, the causes of diastolic dysfunction include high blood pressure, diabetes, coronary artery disease, kidney dysfunction, cancer, genetic disorders, obesity, and inactivity.

摘要 - 收缩与舒张功能障碍
Systolic and diastolic dysfunction are two types of left ventricle heart failures. In systolic dysfunction, the left ventricle cannot contract the way it should due to a weakened left ventricle of the heart. In diastolic dysfunction, the left ventricle cannot relax the way it should due to a stiffer left ventricle. Due to both types of conditions, the left ventricle fails to pump the required amount of blood throughout the body. So, this summarizes the difference between systolic and diastolic dysfunction.
