Breathing involves two phases: breathing in and breathing out. Your lungs deliver oxygen and remove carbon dioxide from your blood in a process called gas exchange. Gas exchange happens in the capillaries surrounding the alveoli, where the oxygen that is breathed in enters the circulatory system and carbon dioxide in the blood is released to the lungs and then breathed out. If you have problems breathing, gas exchange may be impaired, increasing the risk of serious health problems.

Damage to the lung’s air sacs—called alveoli—causes ARDS. Fluid from tiny blood vessels leaks through the damaged walls of the air sacs and collects, limiting the lungs’ normal exchange of oxygen and carbon dioxide. The damage also causes inflammation that leads to the breakdown of surfactant—a liquid that helps keep your air sacs open.

Si su médico recomienda la rehabilitación pulmonar, recibirá la atención de un equipo de proveedores de atención médica, que diseñará un plan que se ajuste a sus necesidades basados en la salud de sus pulmones, su edad y otros factores de salud. Una vez que finalice el programa, el equipo evaluará nuevamente la función pulmonar para ver si la respiración ha mejorado.

Dos de los principales factores de riesgo de enfermedad cardíaca son la presión arterial alta y el colesterol alto en sangre. Si cualquiera de estos números es alto, trabaje con su médico para que alcance un rango saludable.

If you have a known family history of Marfan syndrome or physical features of the condition, your doctor may recommend screening to find the condition early. Relatives of people who have Marfan syndrome may also want to have genetic screening. There is no way to prevent Marfan syndrome.

Your doctor will diagnose peripheral artery disease based on your medical and family histories, a physical exam, and results from one or more tests: ankle-brachial index, Doppler ultrasound, treadmill test, magnetic resonance angiogram (MRA), arteriogram, and blood tests.

Treatments for carotid artery disease may include heart-healthy lifestyle changes, medicines, and medical procedures such as carotid endarterectomy and carotid artery angioplasty and stenting.

Heart valve disease occurs if one or more of your heart valves don't work well. The heart has four valves—the tricuspid, pulmonary, mitral, and aortic valves—that make sure blood flows in the right direction through your heart’s four chambers and to the rest of your body.

Todas las personas mayores de 3 años deben visitar un profesional de la salud para medirse la presión arterial al menos una vez al año. El médico le tomara la presión arterial para ver si las lecturas de la presión arterial son constantemente altas. El médico le hablará sobre cambios en el estilo de vida para un corazón saludable para ayudarle a controlar la presión arterial o evitar la presión arterial alta.

Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body.
