Al comienzo, es posible que la EPOC no cause síntomas o que estos sean leves. A medida que la enfermedad empeora, síntomas comunes incluyen tos (con o sin mucosidad), sensación de falta de aire, sibilancias o un silbido o chillido que se producen al respirar y presión en el pecho.

The TAH replaces the lower chambers of the heart, called ventricles. Tubes connect the TAH to a power source that is outside the body. The TAH then pumps blood through the heart’s major artery to the lungs and the rest of the body.

Many factors play a role in preparing your body to fall asleep and wake up. Your body has several internal clocks, called circadian clocks. These typically follow a 24-hour repeating rhythm, called the circadian rhythm. This rhythm affects every cell, tissue, and organ in your body and how they work.

You may or may not notice atrial fibrillation. It often occurs with no signs or symptoms. If you do have symptoms, you may notice something that occurs only occasionally. Or, your symptoms may be frequent or serious.

Arrhythmia is caused by changes to heart tissue. It can also occur suddenly as a result of exertion or stress, imbalances in the blood, medicines, or problems with electrical signals in the heart. Typically, an arrhythmia is set off by a trigger, and the irregular heartbeat can continue if there is a problem in the heart. Sometimes the cause of an arrhythmia is unknown.

Your doctor may recommend cardiac catheterization to find out what is causing signs or symptoms of a heart problem or to treat or repair a heart problem.

If you have known risk factors for developing an aortic aneurysm, your doctor may recommend screening. To screen for an aortic aneurysm, your doctor may recommend an imaging study to look at and measure the aorta. An aneurysm can develop and grow without any symptoms until it ruptures or dissects—events that are both life-threatening. If the aneurysm is found early, treatment or surgery may slow its growth and prevent rupture or dissection.

Angina happens when your heart muscle does not get enough oxygen-rich blood. Medical conditions, particularly ischemic heart disease, or lifestyle habits can cause angina. To understand the causes of angina, it helps to understand how the heart works.

Typically doctors screen for atrial fibrillation only when you have symptoms. However, your doctor may check for signs of atrial fibrillation as part of your regular medical care. Screening tests include checking your pulse or recording your heart’s electrical activity.

After the procedure to place a coronary stent, carotid stent, or airway stent, you will recover in the hospital for a few hours or overnight. For stent grafts, you may be in the hospital for a longer time. Although not common, you may also experience complications from the stenting procedure.

There are two types of aortic aneurysms: thoracic aortic aneurysms and abdominal aortic aneurysms.

Las causas de la anemia por deficiencia de hierro incluyen la pérdida de sangre, consumir muy poco hierro, problemas para absorber el hierro y ciertas afecciones.

Causes of cardiogenic shock include heart attack and other heart problems, problems outside of the heart, and medicines or procedures. A heart attack is the most common cause because it can damage the heart’s structure in different ways. Less often, a problem elsewhere in the body blocks blood flow coming into or out of the heart and leads to cardiogenic shock.

Your doctor may use diagnostic tests or procedures before CABG to determine how serious your ischemic heart disease is and where the coronary arteries are narrowed. If you need CABG, talk to your doctor about how to prepare for the procedure.

Your risk for a specific type of vasculitis may be higher because of your age, your family history and genetics, infections you have, your lifestyle habits, medicines you take, other medical conditions you have, your race or ethnicity, and your sex.
