What is Cholesterol?Cholesterol is a sterol (a combination steroid and alcohol). Cholesterol is a lipid found in the cell membranes of all tissues, and it is transported in the blood plasma of all animals. Because cholesterol is synthesized by all eukaryotes, trace amounts of cholesterol are also found in membranes of plants and fungi.The name originates from the Greek chole- (bile) and stereos (solid), and the chemical suffix -ol for an alcohol, as researchers first identified cholesterol in solid form in gallstones by Francois Poulletier de la Salle in 1769. However, it is only in 1815 that chemist Eugene Chevreul named the compound "cholesterine".[2]Most of the cholesterol is synthesized by the body and some has dietary origin. Cholesterol is more abundant in tissues which either synthesize more or have more abundant densely-packed membranes, for example, the liver, spinal cord and brain. It plays a central role in many biochemical processes, such as the composition of cell membranes and the synthesis of steroid hormones. Cholesterol is insoluble in blood, but is transported in the circulatory system bound to one of the varieties of lipoprotein, spherical particles which have an exterior composed mainly of water-soluble proteins. The main types, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) carry cholesterol from and to the liver.According to the lipid hypothesis, abnormally high cholesterol levels (hypercholesterolemia) and abnormal proportions of LDL and HDL are associated with cardiovascular disease by promoting atheroma development in arteries (atherosclerosis). This disease process leads to myocardial infarction (heart attack), stroke and peripheral vascular disease. As high LDL contributes to this process, it is termed "bad cholesterol", while high levels of HDL ("good cholesterol") offer a degree of protection. The balance can be redressed with exercise, a healthy diet, and sometimes medication. |

Stroke (Hemorrhagic): Online Reference For Health Concerns Treatment for hemorrhagic stroke depends on the underlying cause. For ICH resulting from hypertension, the initial treatment is blood pressure control.

Excessive and rapid blood loss can cause a severe drop in the mother's blood pressure and may lead to shock and Updated guidelines advise new treatments for brain hemorrhage The first scientifically proven treatments for intracerebral hemorrhage, or ?bleeding,? Reducing high blood pressure is still the best way to avoid ICH, MedlinePlus Medical Encyclopedia: Hemorrhagic stroke The blood pressure may be too high or too low in patients with brain hemorrhage. These problems need to be addressed immediately by doctors. Intracerebral Hemorrhage | Internet Stroke Center The most common cause of intracerebral hemorrhage is high blood pressure (hypertension). Since high blood pressure by itself often causes no symptoms, Hypertensive intracerebral hemorrhage Hypertensive intracerebral hemorrhage is caused by long-term high blood pressure (hypertension). When blood pressure has remained high for a significant IngentaConnect Blood Pressure Surge Precedes Intracerebral Hemorrhage Introduction: Most patients with acute intracerebral hemorrhage (ICH) have very high blood pressure (BP) on presentation, but it is unclear whether such Physiologic Aspects of Porcine Hemorrhage. III. Heart Rate and Immediately after 30% hemorrhage, arterial mean, systolic, and diastolic blood pressure were 79, 104, and 59 mm Hg, respectively. During th 5-hour recovery Bleeding - Wikipedia, the free encyclopedia Hemorrhage generally becomes dangerous, or even fatal, when it causes hypovolemia (low blood volume) or hypotension (low blood pressure). Cerebral hemorrhage - Wikipedia, the free encyclopedia Intracerebral hemorrhage, or ICH, accounts for 10 to 15 percent of all strokes (Weibers 2001). It most frequently results from high blood pressure as found Comparison of Blood Pressure-Associated Risk of Intracerebral However, little information is available on the difference between intracerebral and subarachnoid hemorrhages in relation to blood pressure. Blood pressure: information about, high blood pressure, symptoms Abnormally low blood pressure (hypotension) is observed in infectious and wasting diseases, hemorrhage, and persons who have collapsed. Statins Can Up Brain Hemorrhage Risk After Stroke - Heart Disease In fact, people with severe high blood pressure had more than six times the risk of hemorrhagic stroke compared with people with normal blood pressure. |
