The pericardium (pl.: pericardia), also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. [1] It has two layers, an outer layer made of strong inelastic connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium).
A pericardial effusion with enough pressure to adversely affect heart function is called cardiac tamponade. [1] Pericardial effusions can cause cardiac tamponade in acute settings with fluid as little as 150mL. In chronic settings, however, fluid can accumulate anywhere up to 2L before an effusion causes cardiac tamponade.
A pericardial cyst is an uncommon benign dilatation of the pericardial sac surrounding the heart. It can lead to symptoms by compressing nearby structures, but is usually asymptomatic. [ 1 ] Pericardial cysts can be congenital or acquired, and they are typically diagnosed with radiologic imaging.
Trying to minimize your intake of foods high in saturated fat, trans fat, or cholesterol. Taking steps to minimize your sodium intake. Consuming alcohol in moderation or not at all.
Hemopericardium has been reported to result from various afflictions including chest trauma, free wall rupture after a myocardial infarction, bleeding into the pericardial sac following a type A aortic dissection, and as a complication of invasive cardiac procedures. [6] Acute leukemia has also been reported as a cause of the condition. [7]
These categories are called epicardial (above the epicardium, or the outermost tissue of the heart) and microvascular (close to the endocardium, or the innermost tissue of the heart). [ 2 ] Reduced function of the coronary arteries can lead to decreased flow of oxygen and nutrients to the heart.
The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart. Pericardial fluid is the serous fluid secreted by the serous layer of the pericardium into the pericardial cavity. The pericardium consists of two layers, an outer fibrous layer and the ...
But for some people, a low fat diet may be more effective,” he explained. The study authors, on the other hand, proposed that protein-rich diets could benefit individuals with type 2 diabetes ...
