Acute pericarditis

Acute pericarditis

The heart is covered by two thin membranes (i.e., the pericardium), the visceral and parietal layers. Acute pericarditis is an acute inflammation of these layers and can coexist with myocarditis and endocarditis, either alone or simultaneously. In cases of coexisting conditions, it is often part of a systemic disease or caused by the spread of lesions from adjacent organs or tissues. The typical clinical manifestations are the three major features: chest pain, pericardial friction rub, and characteristic ST-T changes on the electrocardiogram.

Acute heart failure

Acute heart failure

Acute heart failure refers to the acute onset or worsening of cardiac dysfunction, leading to decreased myocardial contractility, increased cardiac load, and a series of changes such as an acute drop in cardiac output, ultimately causing pulmonary congestion and acute pulmonary edema. Acute heart failure is often life-threatening and requires emergency resuscitation.
