In coronary heart disease, the coronary arteries narrow due to the buildup of atheroma or fatty deposits on the vessel walls. The atheroma causes the blood flow of the arteries to be restricted. [6] By restricting the blood flow, the tissue is still receiving some oxygen, but not enough to sustain the tissue over time. [5]
Postoperative wounds are those wounds acquired during surgical procedures. Postoperative wound healing occurs after surgery and normally follows distinct bodily reactions: the inflammatory response, the proliferation of cells and tissues that initiate healing, and the final remodeling.
Traumatic cardiac arrest (TCA) is a condition in which the heart has ceased to beat due to blunt or penetrating trauma, such as a stab wound to the thoracic area. [1] It is a medical emergency which will always result in death without prompt advanced medical care.
A chronic wound is a wound that does not progress through the normal stages of wound healing—haemostasis, inflammation, proliferation, and remodeling—in a predictable and timely manner. Typically, wounds that do not heal within three months are classified as chronic. [ 1 ]
The myofibroblasts are absent in the first trimester in the embryonic stage where damage heals scar-free; [19] in small incisional or excision wounds less than 2 mm that also heal without scarring; [19] and in adult unwounded tissues where the fibroblast in itself is arrested; however, the myofibroblast is found in massive numbers in adult ...
However, if surgery is performed in time, it can offer a chance of survival. [4] Though there is a concern that a small, stable tear in the aorta could enlarge and cause complete rupture of the aorta and heavy bleeding, this may be less common than previously believed as long as the blood pressure does not get too high. [2]
The most common cause of myocardial rupture is a recent myocardial infarction, with the rupture typically occurring three to five days after infarction. [3] Other causes of rupture include cardiac trauma, endocarditis (infection of the heart), [4] [5] cardiac tumors, infiltrative diseases of the heart, [4] and aortic dissection. [citation needed]
The extent of the injury and the age of the injured person may contribute to the likelihood of complications. Infection of wounds is a common complication in traumatic injury, resulting in diagnoses such as pneumonia or sepsis. [63] Wound infection prevents the healing process from taking place and can cause further damage to the body.
