To understand high blood cholesterol (ko-LES-ter-ol), it helps to learn about cholesterol. Cholesterol is a waxy, fat-like substance that’s found in all cells of the body. Your body needs some cholesterol to make hormones, vitamin D, and substances that help you digest foods. Your body makes all the cholesterol it needs. However, cholesterol also is found in some of the foods you eat. Cholesterol travels through your bloodstream in small packages called lipoproteins (lip-o-PRO-teens). These packages are made of fat (lipid) on the inside and proteins on the outside. Two kinds of lipoproteins carry cholesterol throughout your body: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). Having healthy levels of both types of lipoproteins is important. LDL cholesterol sometimes is called “bad” cholesterol. A high LDL level leads to a buildup of cholesterol in your arteries. (Arteries are blood vessels that carry blood from your heart to your body.) HDL cholesterol sometimes is called “good” cholesterol. This is because it carries cholesterol from other parts of your body back to your liver. Your liver removes the cholesterol from your body. What Is High Blood Cholesterol? High blood cholesterol is a condition in which you have too much cholesterol in your blood. By itself, the condition usually has no signs or symptoms. Thus, many people don’t know that their cholesterol levels are too high. People who have high blood cholesterol have a greater chance of getting coronary heart disease, also called coronary artery disease. (In this article, the term “heart disease” refers to coronary heart disease.) The higher the level of LDL cholesterol in your blood, the GREATER your chance is of getting heart disease. The higher the level of HDL cholesterol in your blood, the LOWER your chance is of getting heart disease. Coronary heart disease is a condition in which plaque (plak) builds up inside the coronary (heart) arteries. Plaque is made up of cholesterol, fat, calcium, and other substances found in the blood. When plaque builds up in the arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). Atherosclerosis Over time, plaque hardens and narrows your coronary arteries. This limits the flow of oxygen-rich blood to the heart. Eventually, an area of plaque can rupture (break open). This causes a blood clot to form on the surface of the plaque. If the clot becomes large enough, it can mostly or completely block blood flow through a coronary artery. If the flow of oxygen-rich blood to your heart muscle is reduced or blocked, angina (an-JI-nuh or AN-juh-nuh) or a heart attack may occur. Angina is chest pain or discomfort. It may feel like pressure or squeezing in your chest. The pain also may occur in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion. A heart attack occurs if the flow of oxygen-rich blood to a section of heart muscle is cut off. If blood flow isn’t restored quickly, the section of heart muscle begins to die. Without quick treatment, a heart attack can lead to serious problems or death. Plaque also can build up in other arteries in your body, such as the arteries that bring oxygen-rich blood to your brain and limbs. This can lead to problems such as carotid artery disease, stroke, and peripheral arterial disease (P.A.D.). Outlook Lowering your cholesterol may slow, reduce, or even stop the buildup of plaque in your arteries. It also may reduce the risk of plaque rupturing and causing dangerous blood clots.

Featured Video The NHLBI "Grand Opportunity" Exome Sequencing Project05/16/2012 This video—presented by the National Heart, Lung, and Blood Institute, part of the National Institutes of Health—discusses the NHLBI's Exome Sequencing Project. Made possible by the American Recovery and Reinvestment Act of 2009, this project provided six awards at five academic institutions to identify genetic connections to heart, lung, and blood diseases. Individual studies will address critical health issues, such as heart attack, stroke, COPD (chronic obstructive pulmonary disease), high blood cholesterol, high blood pressure, overweight and obesity, and others.

Neke činjenice o Kolesterol Sa svim vijestima i upozorenja o kolesterola, točnije o opasnostima visokog kolesterola, mnogi ljudi vidjeli kolesterol kao "lošeg" tvari koje treba eliminirati u potpunosti iz naših života. U istini, kolesterola služi neke važne funkcije u tijelu. Da bi razumjeli kako kolesterola utječe na tijelo, prvo moramo shvatiti što je kolesterol. Kolesterol je voštana supstanca koja je pričvršćena na masti u krvotok, te je prisutan u svim stanicama tijela. Kolesterol dolazi iz hrane koju jedemo, kao i da je proizvedena izravno u jetri. Kolesterol je važan regulator u krvotok, kao što pomaže regulirati formiranje mnogih stanica kao što su hormoni. Međutim, da ima previsok ili prenizak od grofa kolesterola u krvi može biti vrlo opasno čimbenik, često dovodi do srčanog ili moždanog udara. Iako je kolesterol je rasprostranjen u krvotok, ne može raspršiti u krvi. Kolesterolske manevri u cijelom tijelu u prilogu lipida (masti). Postoje dvije glavne vrste kolesterola. Prvi tip se zove LDL kolesterola, a drugi je HDL kolesterola. LDL kolesterol, inače poznat kao lipoproteina niske gustoće, smatra "opasnim" kolesterola. LDL kolesterol može izgraditi na stijenkama arterija. Tijekom vremena ova ploča graditi-gore blokira protok krvi, smanjuje cirkulaciju i uzrokuje stres i oštećenja na srcu. To podiže krvni tlak, i na kraju dovodi do bolesti srca ili srčanog udara. Pojedinci koji imaju višu razinu LDL pokrenuti mnogo veći rizik od bolesti srca. Iako LDL utječe genetika, postoji nekoliko mjera opreza koje pojedinci mogu poduzeti prema održavanju sigurne razine LDL. Drugi oblik kolesterola HDL, ili visoke gustoće lipoproteina. HDL smatra "dobar" kolesterol. HDL kolesterol je važan za tijelo imati ovaj tip kolesterola pomaže filtrirati LDL kolesterol od stijenkama arterija, kao i prijevoz masnoća u krvi (trigliceridi) u jetri, tako da se mogu izlučiti iz tijela. Smatra se da su i imaju visoke razine HDL je siguran, kao što može pomoći u zaštiti svoje srce od srčanog ili moždanog udara. Niske broji HDL potencijalno može dovesti do srčanog i moždanog udara, no to je rijetkost za osobe jedući zapadnjačkog stila prehrane, koja je obično visoka u oba oblika kolesterola. Većina kolesterola u našem tijelu dolazi iz hrane koju jedemo. Hrane visoke u masti, osobito zasićene i trans masti, doprinose visoke razine LDL kolesterola. Meso i mliječni proizvodi su glavni izvori LDL kolesterola, dok je lisnato povrće, voće, i orašasti plodovi su više hranjiv alternative koje imaju višu razinu HDL kolesterola. Dok genetika ne igra ulogu u razini kolesterola, a change in diet is the most effective way to lower dangerous cholesterol levels, and reduce your risk of heart disease and associated health problems. Certain natural substances found in Vasacor, including plant sterols, fish oils, and policosanol have been shown in numerous clinical studies to be highly effective in promoting healthy cholesterol levels, particularly when combined with a healthy diet and exercise. If you are concerned about your cholesterol levels, now is the time to make a change, and Vasacor can help.
