When people do not have cardiac tamponade, doctors do not usually use pericardiocentesis to diagnose fluid around heart spaces unless the medical team is concerned about bacterial infection. Researchers report that although the procedure is risky, it can be a potentially lifesaving technique for people with cardiac tamponade. The consistency of the fluid, which could be either watery or high in protein, helps doctors determine what is causing the fluid buildup and how best to treat it. Sometimes, it is necessary to leave a drain in the pericardial space to remove all the fluid from the sac. This procedure involves using a needle to remove a sample of the fluid around the heart for analysis. Pericardiocentesis is another important tool that doctors use to determine what causes pericardial effusion. This test can also show doctors the amount and location of the fluid. When a doctor suspects that a person has this condition, researchers recommend that they use an echocardiogram as their first diagnostic tool. Medical imaging is an effective way to determine whether someone has fluid around the heart. analyzing fluid samples from the pericardium.If the individual has multiple symptoms and a lot of fluid, doctors are more likely to use drainage techniques.Īccurately diagnosing the cause of a fluid buildup around an individual’s heart involves the following steps: As it is potentially life threatening, it is important to take these symptoms very seriously:ĭoctors tend to opt for conservative treatment of pericardial effusion when the affected individual does not have any symptoms and the amount of fluid is small. This condition is called cardiac tamponade. When fluid builds up rapidly in the pericardium, it puts so much pressure on the heart that this organ cannot do its job properly. chest pain that gets worse when people lie flat.However, when fluid does build up, it puts pressure on nearby organs and parts of the body, including the lungs, stomach, nerves, and heart. Whether or not a person presents with symptoms often depends on how rapidly the fluid accumulates, rather than on the amount of fluid.įluid around heart spaces does not always cause symptoms, especially in the early stages, because the pericardium can stretch. Improved understanding of this multifaceted pathophysiology has driven the development of improved treatment modalities, such as beta-blockers and angiotensin converting enzyme inhibitors which are now mainstays of heart failure therapy.įurther investigation into the neurohumoral mechanisms activated in the heart failure patient is a promising avenue for advances in diagnosis, prognosis, and treatment of this prevalent and devastating disease.The pericardial sac typically contains 10–50 milliliters of fluid, but when pericardial effusion develops, the fluid quantity can increase and cause a variety of reactions throughout the body. However, prolonged activation of these systems contributes to sodium and fluid retention, increased preload and afterload, and further damage to the myocardium. The activation of several neurohumoral mechanisms including the sympathetic nervous system, renin-angiotensin-aldosterone axis, nonosmotic arginine vasopressin release, and natriuretic peptide release initially compensates for depressed myocardial function. We performed a review of clinical texts as well as a Medline investigation for the pathophysiology of fluid and sodium retention in heart failure.Ī breakdown in the integrity of the arterial circulation, seen in both high and low output heart failure, triggers a complex cascade of maladaptive events in an effort to maintain cardiorenal homeostasis. Fluid retention in the face of an expanding extracellular fluid volume is a key contributing factor in the development and progression of heart failure. ![]()
