Medical Definition of subacute 1 : falling between acute and chronic in character especially when closer to acute subacute endocarditis. 2 : less marked in severity or duration than a corresponding acute state subacute pain.
Chronic conditions can often be managed (like diabetes or high blood pressure). A newly diagnosed illness can also be labeled chronic if there is no expectation of a cure; arthritis is one such example.
In medicine, describing a disease as acute denotes that it is of short duration and, as a corollary of that, of recent onset.

acute respiratory distress syndrome (ARDS) a group of symptoms accompanying fulminant pulmonary edema and resulting in acute respiratory failure; called also shock lung, wet lung, and many other names descriptive of etiology or clinical manifestations. Many etiologic factors have been associated with ARDS, including shock, fat embolism, fluid overload, oxygen toxicity, fluid aspiration, narcotic overdose, disseminated intravascular coagulation, multiple transfusions, inhalation of toxic gases, diffuse pulmonary infection, and systemic reactions to sepsis, pancreatitis, and massive trauma or burns.

acute stress disorderan anxiety disordercharacterized by development of anxiety, dissociation, and other symptoms within one month following exposure to an extremely traumatic event, the symptoms including reexperiencing the event, avoidance of trauma-related stimuli, anxiety or increased arousal, and some or all of the following: a subjective sense of diminished emotional responsiveness, numbing, or detachment, derealization, depersonalization, and amnesia for aspects of the event. If persistent, it may become posttraumatic stress disorder.
ARDS is characterized clinically by dyspnea, tachypnea, tachycardia, cyanosis, and hypoxemia. PaO2/FIO2remains low (below 2 cc) even with oxygen therapy at high oxygen concentrations. The lung compliance is decreased so that the lung is stiffer and more difficult to ventilate. Chest radiographs show signs of bilateral interstitial and alveolar edema. Cardiac filling pressures are normal, and the pulmonary capillary wedge pressure is below 18 torr.
Some authorities refer to a fourth phase or stage of ARDS, the period after the resolution or recovery stage. Some patients continue to experience health problems caused by the acute illness, such as coughing, limited exercise tolerance, and fatigue. Anxiety, depression, and flashback memories of the critical illness may also occur and be similar to posttraumatic stress disorder.
A chronic condition characterized by the body's inability to process glucose (sugar) in the bloodstream. The pancreas secretes insulin, a hormone that causes glucose to be moved from the bloodstream into the cells, where it is used for energy. In a person with diabetes, either the pancreas fails to make enough insulin, or the body's cells are unable to respond to insulin. Either situation causes glucose levels in the bloodstream to increase.
