Sudden cardiac arrest is an emergency. A person having sudden cardiac arrest needs to be treated with a defibrillator to send an electric shock to the heart right away to restore normal heart rhythm. Use of automated external defibrillators and CPR can be performed by bystanders. If you survive sudden cardiac arrest, you’ll likely be admitted to the hospital for ongoing care and treatment.

Heart-healthy lifestyle changes are the first line of treatment for metabolic syndrome. If lifestyle changes aren’t enough, your doctor may prescribe medicines.

La exposición prolongada a irritantes pulmonares (humo de cigarrillo, aire contaminado, la presencia de vapores químicos, o el polvo) que lesionan los pulmones y las vías respiratorias es la causa de la EPOC. Una rara alteración genética llamada deficiencia de alfa-1-antitripsina (AAT) puede también causar la enfermedad.

Se desconoce exactamente qué produce el asma, y las causas pueden variar de una persona a otra. A menudo, el asma es el resultado de una fuerte respuesta del sistema inmunológico a un alérgeno en el medioambiente. Por ejemplo, la exposición a un alérgeno en el medioambiente, como la ambrosía, puede hacer que sus vías aéreas reaccionen fuertemente. Es posible que otras personas expuestas al mismo alérgeno no reaccionen en absoluto, o que su respuesta sea diferente. La razón por la que una persona reacciona a una exposición, mientras que otras no lo hacen, no se entiende por completo, aunque se lo puede explicar parcialmente por medio de los genes.

Ventricular fibrillation, a type of arrhythmia, causes most sudden cardiac arrests. Other problems with the heart's electrical system, including diseases or conditions that can cause the electrical problems—such as coronary heart disease, physical stress, certain inherited disorders, and structural changes in the heart—also can lead to sudden cardiac arrest.

Hasta el momento, la EPOC no tiene cura. Sin embargo, los cambios en el estilo de vida y los tratamientos pueden lograr que usted se sienta mejor, permanezca más activo, y pueden retrasar la progresión de la enfermedad.

The body’s muscles and nervous system help control your breathing. The lungs are like sponges; they cannot move on their own. Muscles in your chest and abdomen contract, or tighten, to create space in your lungs for air to flow in. The muscles then relax, causing the space in the chest to get smaller and squeeze the air back out. Your breathing usually does not require any thought, because it is controlled by the autonomic nervous system, also called the involuntary nervous system.

Treatment for iron-deficiency anemia will depend on its cause and severity. Treatments may include iron supplements, red blood cell transfusions, changes in your eating pattern, or procedures like endoscopy to stop bleeding.

There are three main types of ischemic heart disease: obstructive coronary artery disease; nonobstructive coronary artery disease; and coronary microvascular disease.

Your doctor may recommend a stent to provide support inside an artery that has become narrowed by plaque buildup from atherosclerosis, or for lung airways that have narrowed due to other medical conditions. Your doctor will discuss the risks and benefits of the procedure with you. Sometimes, a stenting procedure is not recommended or another procedure is recommended instead. Learn more about the use of stents in the following conditions.
