Many people who have conduction disorders, such as first-degree AV block, may have no obvious signs or symptoms. Others may have signs and symptoms that occur in specific situations, such as when you experience physical or emotional stress or when you sleep. Conduction disorders can lead to life-threatening arrhythmias if undiagnosed or untreated.

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.

Hay muchos factores de riesgo para la enfermedad coronaria. Su riesgo de padecer la enfermedad coronaria aumenta con la cantidad de factores de riesgo que tiene y con la gravedad de estos. Algunos factores de riesgo, como la presión arterial alta y el colesterol alto en la sangre, se pueden cambiar a través de cambios en el estilo de vida para un corazón saludable. Otros factores de riesgo, como la edad avanzada, el historial familiar y genético, la raza, la etnia y el sexo, no pueden cambiarse.

Las terapias genéticas pueden utilizar métodos de transferencia de genes o edición genómica para modificar el ADN de las células de un paciente, con el objetivo de prevenir o tratar una afección.

The signs, symptoms, and complications of vasculitis vary depending on which type of vasculitis you have, the organs involved, and the severity of the condition. Some people may have few signs and symptoms. Other people may become very sick.

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.

Signs and symptoms of DIC depend on whether the condition is acute or chronic. Acute DIC is more severe and develops quickly over hours or days. Chronic DIC happens more slowly and sometimes has no signs or symptoms. Complications from DIC can occur from both the clotting that happens in the early stages of the condition and from bleeding in the later stages. Serious complications include organ damage and hemorrhage.

Los signos, síntomas y complicaciones pueden variar según el tipo de trastorno hemorrágico, su causa y si el trastorno es leve o más grave. Los signos y síntomas pueden ser obvios poco después del nacimiento de un niño o pueden no aparecer hasta la edad adulta. Las personas que tienen un trastorno hemorrágico leve pueden no tener ningún signo o síntoma hasta que se lesionen o tengan un procedimiento médico.

Su riesgo de desarrollar trastornos hemorrágicos puede aumentar por la edad, el historial familiar y genético, otras afecciones médicas y medicinas, y el sexo.

Marfan syndrome is a genetic condition caused by a mutation, or change, in one of your genes, called the fibrillin-1 (FBN1) gene. The FBN1 gene makes fibrillin-1, which is a protein that forms elastic fibers within connective tissue. Fibrillin-1 also affects levels of another protein that helps control how you grow.

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.

Desequilibrios energéticos, algunas afecciones genéticas o endocrinas y ciertos medicamentos producen sobrepeso y obesidad.

It is important to have regular blood pressure readings taken and to know your numbers, because high blood pressure usually does not cause symptoms until serious complications occur. Undiagnosed or uncontrolled high blood pressure can cause complications such as chronic kidney disease, heart attack, heart failure, stroke, and possibly vascular dementia.

Pneumonia occurs when certain bacterial, viral, and fungal infections cause inflammation in the air sacs, or alveoli, of the lungs. Some of the more common causes in the United States include Streptococcus pneumoniae or pneumococcus bacteria, the influenza or flu virus, and respiratory syncytial virus (RSV).

To diagnose hypersensitivity pneumonitis, your doctor will collect your medical history, assess exposure history to possible causative substances, perform a physical exam, and possibly order diagnostic tests and procedures such as: blood tests, bronchoalveolar lavage (BAL), computed tomography (CT), inhalation challenge tests, lung biopsies, lung function tests, precipitin tests, or chest x-rays.
