心 & 血管
心绞痛
心绞痛 is chest pain caused by reduced blood flow to your heart muscle. It is a symptom of coronary artery disease (计算机辅助设计), 当向心脏供血的动脉阻塞或变窄时，会发生什么.
主动脉瘤和主动脉夹层
主动脉瘤是一种气球状的凸起, caused by weakness or degeneration in the wall of the aorta, the body’s primary and largest artery that runs from the heart, 穿过胸部，进入腹部.
主动脉瓣疾病
主动脉瓣控制从左心室泵出心脏进入主动脉的血液流量, 通往身体其他部位的主动脉. 主动脉瓣疾病是指主动脉瓣受损，导致主动脉瓣不能正常工作.
心律失常
An arrhythmia is a problem with the speed or rhythm of your heartbeat, caused by abnormal electrical activity in the heart. 心律不齐会使你的心跳过快、过慢或有不规则的节律.
心房纤颤
心房颤动(AF)是一种源自心脏上两腔(心房)的异常心律。. 在心房纤颤, the atria beat out of sync with the lower two chambers of the heart (心室). AF is the most common type of arrhythmia, or irregular heart rhythm.
Brugada综合症
Brugada综合征是一种遗传性疾病，会导致潜在的危及生命的心律紊乱. Occurring in the lower chambers (ventricles) of your heart, 这些干扰会导致混乱的电活动，导致心脏颤抖，不能有效地将血液泵到身体的其他部位. The result may be fainting and, eventually, cardiac arrest.
癌症相关的心脏疾病
一些癌症治疗方法会导致心脏病, 心肌衰弱(心肌病), 或心脏肿瘤. Another condition, cardiac amyloidosis, is sometimes linked to multiple myeloma. 虽然手术可以治疗一些心脏肿瘤, 不能通过手术切除的原发性或继发性肿瘤通常是致命的.
心脏结节病
结节病是一种知之甚少的疾病，它是一种异常免疫细胞团块(肉芽肿)形成的疾病, 最典型的是肺部, 但有时在心里. Cardiac granulomas cause inflammation that can result in the scarring of heart tissue. Genetics are thought to be a significant factor in the development of sarcoidosis.
颈动脉疾病
颈动脉疾病(或颈动脉狭窄)发生时，主要动脉在你的颈部, 将富含氧气的血液输送到你的大脑, become narrowed and potentially blocked by the buildup of plaque (atherosclerosis). 颈动脉, 在你脖子的两边, run from your aorta (in your chest) to your brain. Carotid artery disease is a form of peripheral artery disease.
冠状动脉疾病
冠状动脉是为心脏肌肉提供富氧血液的大血管. Coronary artery disease (计算机辅助设计) occurs when these 动脉 become blocked. 计算机辅助设计, 通常是几十年累积起来的, 是最常见的心脏病形式吗?是全球范围内心脏病相关死亡的主要原因吗.
深静脉血栓形成
Deep vein thrombosis (DVT) is a blood clot that forms, 通常是腿部的静脉, 当你的血流量变得非常缓慢时.
糖尿病性心脏病
心 disease is the most common long-term complication of diabetes. 糖尿病 is now regarded as one of the strongest risk factors for heart disease. The risk worsens when combined with other common risk factors for heart disease.
心脏病
当冠状动脉因斑块破裂和血栓形成而完全阻塞时，就会发生心脏病。, 阻止血液流向心脏肌肉. 如果血流不能很快恢复, the section of heart muscle becomes damaged from lack of oxygen and begins to die.
心脏病
“心脏病”指的是可以影响心脏不同部位的许多疾病, 或者你的心脏运作的方式.
心脏衰竭
虽然听起来很吓人, 心力衰竭通常是一种慢性疾病, 这意味着它可以被治疗和管理. 有时，心力衰竭是可以治愈的.
高血压(高血压)
血压是测量血液在血管中流动的强度. 当你的血压持续过高时，就会发生高血压.
高胆固醇(高脂血症)
Having hyperlipidemia means there are too many lipids (fats) in your blood. Cholesterol and triglycerides are the two main types of fats in your blood; the more there is of each, the higher the risks to your heart and vascular health.
长QT综合征
长QT综合征(LQTS)是一种罕见的心电节律紊乱，可发生在其他健康的人. It can potentially cause fast, chaotic heartbeats that can lead to fainting. In some cases, your heart's rhythm may be so erratic that it can lead to sudden death. 但总的来说，QT间期延长综合症是可以治疗的.
二尖瓣疾病
二尖瓣控制心脏左侧上(心房)和下(心室)腔间的血液流动. 二尖瓣疾病是指二尖瓣受损，导致其功能不正常.
心包疾病(心包炎)
Pericarditis is an inflammation of the pericardium, 薄, 双层, fluid-filled sac that covers the outer surface of your heart. The pericardium is designed to shield your heart from infection, as well as to keep the heart from expanding too much when blood volume rises.
外周动脉瘤
外周动脉瘤是指影响动脉而不是主动脉或大脑的动脉瘤. 周围动脉瘤最常见的并发症是血栓的形成，这可能会阻碍血液通过动脉流动.
外周动脉疾病
Peripheral artery disease (垫) affects an estimated eight to 12 million Americans. 垫, a circulation problem in which narrowed 动脉 reduce blood flow to your limbs, can increase the risk of stroke and heart attack. 垫 may cause pain and sores, and potentially lead to loss of limb(s).
肺栓塞
A pulmonary embolism is the sudden blockage of a major artery in your lung, 当你身体的另一部分形成的血块破裂并进入肺部时就会发生. 肺栓塞是最常见的心血管疾病，仅次于心脏病和中风.
蜘蛛静脉
蜘蛛静脉是一组薄薄的毛细血管(小血管)，位于你的皮肤表面. Spider veins mostly show up on your legs and face; on your legs, they often surround varicose veins. 虽然不是一个严重的医学问题，但对许多人来说，蜘蛛静脉是一个美容问题.
中风
中风是美国第四大死亡原因，但也是致残的主要原因. 中风 is a brain injury that affects the brain’s blood supply.
心脏骤停
心脏骤停(也称为心脏猝死)是由于心脏功能突然丧失而导致的死亡. Unless treatment with a defibrillator is given within minutes, 症状出现后不久就会死亡.
室上性心动过速
患有室上性心动过速(SVT)的人通常在他们的心脏中有一个额外的电路，可能偶尔会经历与运动无关的非常快的心跳(心律失常), 热或压力. When SVT occurs, the heart rate can reach up to 200 beats per minute or more.
胸廓出口综合征
胸廓出口综合征 (TOS) involves compression of the nerves, 动脉, 而下颈部和上胸部区域的静脉会引起手臂的各种症状, 肩膀, and neck depending on anatomic structure most compressed. Symptoms include pain, swelling, tingling or numbness among others.
静脉曲张
As many as 40 million Americans suffer from varicose veins, swollen veins that can be seen just under your skin's surface. 最常见于腿部或骨盆区, 静脉曲张是不正常的, 扩张的血管通常呈蓝色, 膨胀和扭曲. Sometimes varicose veins are surrounded by thin red capillaries called spider veins.
血管炎
“血管炎”这个术语用于与血管炎症有关的几种疾病. 血管炎 is classified as an autoimmune disease, 因为当你的免疫系统攻击和损害你的动脉和静脉时，血管会发炎.
静脉溃疡
Venous ulcers are open sores or wounds that recur or will not heal, 腿上的静脉被破坏并渗透到皮肤深处后就会出现. Venous ulcers are usually found on the inner part of your leg, just above your ankles. 静脉溃疡通常发生在静脉曲张附近的皮肤上，可影响一条或两条腿.
室性心动过速
室性心动过速(v - tachi)是一种异常的心跳(心律失常)，开始于心脏的下部腔, 心室. 心动过速, 心跳加快, usually occurs when the electrical signals in your heart are sent too quickly. This keeps your heart from pumping enough blood and oxygen through your body. 大多数室性心动过速患者的心率至少为每分钟170次.
Wolff-Parkinson-White综合症
沃尔夫-帕金森-怀特综合征(WPW)是一种心律失常的类型，其特征是心脏有一个额外的电通路(电路). As a result, the electrical signal may arrive at 心室 too soon. 这种情况会导致间歇性的心率过快(心动过速或室上性心动过速)。. 沃尔夫-帕金森-怀特综合征是婴幼儿心率失调最常见的原因之一, and is believed to be a congenital heart defect.
