收缩和舒张功能障碍有什么区别

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。

Heart failure当心脏无法将所需的血液泵入身体以保持健康时发生。它可以发生在心脏的左侧或右侧或两侧。因此，它可以分为两个主要部分：左心室心力衰竭和右心室心力衰竭。在左心室心力衰竭中，心脏无法将足够的血液抽到身体。左心室心力衰竭有两种类型：收缩和舒张功能障碍。

什么是收缩功能障碍？

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.

可以通过身体检查，心电图，胸部X射线，超声心动图，运动测试和心脏导管插入术来诊断收缩功能障碍。此外，收缩功能障碍的治疗方法可能包括改变生活方式（跟踪健康饮食，定期运动，锻炼健康的饮食和戒烟），药物（利尿剂，ACE抑制剂，β受体阻滞剂，β受体阻滞剂，矿物皮质激素受体拮抗剂，硝酸盐和氢化氮氨酸，硝酸盐剂，硝酸盐剂，硝酸，地高辛，SGLT2抑制剂）以及手术和装置（左心室辅助装置（LVAD），心脏移植）。

什么是舒张功能障碍？

舒张功能障碍是由于左心室硬化而导致的心力衰竭。在这种情况下，心脏无法像应有的方式放松。发生这种情况时，左心室无法像往常一样充满血液。因此，左心室中的血液较少，将血液泵出来的血液较少。舒张期功能障碍可能是由于高血压，糖尿病，冠状动脉疾病，肾功能障碍，癌症，遗传疾病，肥胖和不活动而引起的。舒张功能障碍的常见症状是呼吸急促，疲倦，无力，脚，脚踝，腿部或腹部肿胀（水肿），持久的咳嗽，喘息，喘息，恶心，缺乏食欲，头晕，混乱，撒尿，以及撒尿。

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.
• 他们可能会显示类似的协会toms.
• They are treated through lifestyle changes, medications, and surgeries.

收缩和舒张功能障碍有什么区别？

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.
