Pulmonary Hypertension

What Is Pulmonary Hypertension?

肺动脉高压指的是肺动脉中的高血压. 肺动脉是将缺氧血液从心脏输送到肺部的血管.

Pulmonary Hypertension vs. Hypertension

肺动脉高压是高血压的一种，但它与高血压有很大的不同 hypertension in the rest of your blood vessels. 全身的高血压被称为全身性高血压.

全身性高血压是指血液在血管中流动的压力过高. 肺动脉高压是指血液流经肺部血管的压力过大. The difference is where the problem occurs in the body.

Types of Pulmonary Hypertension

肺动脉高压是一个广义的术语，因为这种情况可能有许多不同的原因. 世界卫生组织将肺动脉高压分为五种类型, based on the underlying cause:

Group 1—This is also known as pulmonary arterial hypertension (PAH). This type of pulmonary hypertension is rare. You may have inherited pulmonary hypertension. 也可能是由于自身免疫性疾病、感染或毒素暴露引起的. 甲基苯丙胺是导致肺动脉高压最常见的毒素之一. 有甲基苯丙胺使用史会增加患肺动脉高压的风险, even if you no longer use the substance. 有些人也会因为大发娱乐不了解的原因而出现肺动脉高压（特发性肺动脉高压）。.

Group 2—影响心脏左侧的心脏病，比如二尖瓣疾病， aortic valve disease, or heart failure causes this type. This is a more common cause of pulmonary hypertension.

Group 3—这些类型的肺动脉高压是由肺部疾病引起的，如 chronic obstructive pulmonary disease (COPD) or interstitial lung disease. This type may also be caused by sleep apnea.

Group 4—你会因为肺部的慢性血栓而患上肺动脉高压.

Group 5—这一组包括由各种各样的疾病引起的肺动脉高压，这些疾病之间的联系还没有得到很好的理解. 这包括血液紊乱、代谢紊乱、 sarcoidosis, and vasculitis.

Pulmonary Hypertension Symptoms

You may notice that usual activities, such as climbing stairs or taking a walk, are suddenly difficult. Shortness of breath 是大多数人肺动脉高压的第一个症状，其他症状包括：

Chest pain
Fainting
Fatigue
Heart palpitations
Leg swelling
Abdominal distension
Feeling full too quickly when eating

不幸的是，当你出现症状时，肺动脉高压已经处于晚期. 一旦你注意到任何微小的变化，立即去看你的医疗保健大发娱乐提供者进行评估.

Does Pulmonary Hypertension Cause High Blood Pressure?

Pulmonary hypertension is a kind of high blood pressure affecting only your pulmonary arteries. 但肺动脉高压不会引起全身高血压.

What Are the Stages of Pulmonary Hypertension?

医生根据你的运动能力来判断你的肺动脉高压阶段.

Stage 1: You can complete all your usual activities without symptoms.
Stage 2: 在参加日常活动时，你有轻微的限制.
Stage 3: 你注意到自己在日常活动中的能力发生了重大变化.
Stage 4: 你几乎不能做任何身体活动而没有症状，休息时也可能有症状.

How Is Pulmonary Hypertension Diagnosed?

大发娱乐将使用几种测试来诊断肺动脉高压，并找出更多的根本原因：

An electrocardiogram (EKG) 检查心律，寻找右心室增大的迹象.
An echocardiogram 心脏的超声检查是观察心脏腔室的功能和大小以及瓣膜的功能吗. 这种扫描也可以用来估计肺动脉的压力.
Pulmonary function tests 看看你的肺活量和你的肺交换氧气的能力.
A ventilation/perfusion (V/Q) scan 测量氧气和血液在肺部的流动情况，并检测慢性血栓的迹象.
A right heart catheterization measures the pressure in your pulmonary arteries. 这是诊断肺动脉高压的金标准.

Pulmonary Hypertension Treatment

肺动脉高压的治疗取决于病情的根本原因：

持续气道正压通气（CPAP）纠正睡眠呼吸暂停
Medications to help your pulmonary arteries open
B血液稀释剂和手术或导管为基础的程序，以清除血凝块

In advanced stages, you may need a lung transplant to treat pulmonary hypertension. 只有当你用尽所有其他治疗方法都没有成功时，大发娱乐才会大发娱乐提供肺移植手术.
