The fissure may be increased in vertical height in Graves' disease, which is manifested as Dalrymple's sign. It is seen in disorders such as cri-du-chat syndrome. In animal studies using four times the therapeutic concentration of the ophthalmic solution latanoprost, the size of the palpebral fissure can be increased. The condition is reversible.
However, heart disease specifically refers to conditions affecting the heart, while cardiovascular disease is a broader term referring to conditions that affect the heart or blood vessels. Strokes ...
The tracking of blood within the artery wall (both in the presence or absence of an intimal tear) is referred to as a "false lumen". [10] [11] [12] The restriction of blood flow in the 'true' lumen limits the availability of oxygen and nutrients to the heart muscle, or myocardium. As a result, the myocardium continues to demand oxygen but is ...
This blood clot may then restrict blood flow within the heart, leading to heart tissue damage, or a myocardial infarction, also known as a heart attack. [ 1 ] Coronary thrombosis is most commonly caused as a downstream effect of atherosclerosis , a buildup of cholesterol and fats in the artery walls.
Vascular disease is a subgroup of cardiovascular disease. Disorders in this vast network of blood and lymph vessels can cause a range of health problems that can sometimes become severe, and fatal. [3] Coronary heart disease for example, is the leading cause of death for men and women in the United States. [5]
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]
Blood pressure should be lowered a maximum of 10% over the first hour and 25% over the first two hours as rapid lowering of blood pressure can lead to decreased blood flow in the brain and cause the development of an ischemic stroke. Once blood pressure is stabilized, patients can be changed from intravenous medications to oral. [3]
Exsanguination is the loss of blood from the circulatory system of a vertebrate, usually leading to death. The word comes from the Latin 'sanguis', meaning blood, [1] and the prefix 'ex-', meaning 'out of'. Exsanguination has long been used as a method of animal slaughter.
