Why do people with cardiac tamponade get very short of breath?

Compresses heart. The fluid around the heart compresses the heart so that it cannot fill properly. Therefore, the output of blood decreases so that less blood is pumped to the lungs and less to the resto fo the body. Thre is just not enough space ofr the heart to function normally and that will make you short of breath. Also, whatever caused the effusion may also affect the lungs, such as lung cancer.
Decreased blood flow. Tamponade is by definition a constriction of the heart. The heart can not pump normally. Since bloodflow is decreased, so is the amount amount of oxygen delievered. Additonally, blood pressure in the lungs accumulates, since it is upstream from the problem, causing the lungs to engorge with fluid, leading to increased lung stiffness, and difficulty beathing.

Need eval. Given the nonspecific symptoms, differential diagnosis is wide. It appears you're concerned enough that tamponade is crossing your mind! As 8 months have passed, I suspect less acute conditions unless there has been recent progression or change. I strongly recommend physical exam and initial work up might be needed.

Hi doctors, was just wondering what is cardiac tamponade cholesistisis?

Two diagnoses. Two different diagnoses. Cardiac tamponade occurs when fluid build up around the heart causes problems with the heart filling, which can be a life threatening condition. Cholecystitis is inflammation of the gallbladder.

What is cardiac tamponade?

Tamponade. Cardiac tamponade relates to impaired diastolic filling as a consequence of pericardial-ventricular pressure interactions wherein increasing pericardial pressures due to pericardial effusion exert a negative effect on ventricular filling resulting a drop in cardiac output and bp. Discordant effects between the right and left ventricular diastolic filling during inspiration (pulsus paradoxus).
Compression. Of a chamber of heart by extrinsic compression such as from fluid or clot in the pericardium compressing on a ventricle or atrium.

What is and what causes cardiac tamponade?

Fluid under pressure. The heart is surrounded by an envelope called the pericardial sac. When fluid develops in the sac, it can build up pressure resulting in what's called a cardiac tamponade. The heart being a pump cannot effectively perform its function against this pressure unless the fluid is removed.
Fluid around heart. The pericardium is a "skin" surrounding the heart. It is usually empty, though can fill with fluid -from heart failure, autoimmune dz, cancer or infection- or blood from trauma. When the fluid builds up enough pressure to prevent the heart from expanding to fill with blood, tamponade results. This is life-threatening and requires immediate drainage to prevent cardiovascular collapse.

In what way is cardiac tamponade cholesistisis spread?

Cardiac tamponade. Cardiac tamponade and cholecystitis are two diffrent kinds of problems effect two different organs. There is no such thing like spread for these diseases. Your question is not clear.
Confused. Cardiac tamponade is a condition in which the non-elastic pericardial sac surrounding the heart fills with fluid which interferes with cardiac filling. Cholecystitis is acute inflammation of the gall bladder. The 2 conditions are unrelated and neither one "spreads". I'm sorry, I'm not sure what you're asking.

What are the presenting symptoms of cardiac tamponade?

Tamponade Symptoms. Cardiac tamponade is caused by fluid or blood collecting aroung the heart constricting the heart and not allowing it to fill correctly resulting in low blood pressure. Symptoms usually include shortness of breath, weakness, coming close to passing out, or passing out. Chest pain is not uncommon due to irritation of the lining of the heart. It gets better sitting up and worse lying down.
