INTRODUCTION
Atherosclerosis, a disease that hardens and thickens arterial walls, consists of multiple components such as the following: fat components, cholesterol, and cellular waste products. These components produce a build up in the lining of the arteries.1 Smoking and medical conditions such as elevated triglycerides, elevated cholesterol, and high blood pressure can cause atherosclerosis.1 As a result of the collection of these components, arteries accumulate plaque, which consists of fatty deposits inside the smooth muscle of the arteries.1 Medication can improve high-density lipoprotein (HDL) levels, which benefits arteries, and medication can decrease low-density lipoprotein (LDL) levels, triglyceride (TG) levels, and total cholesterol (TC) levels, which also benefits arteries. Medications that can benefit arteries consist of the following: rosuvastatin (Crestor), atorvastatin (Lipitor), simvastatin (Zocor), pravastatin (Pravachol), and fluvastatin (Lescol). The medications, composed of statins that reduce LDL levels, TG levels, and TC levels, also increase HDL levels. Statins, composed of 3-hydroxy-3-methylglutaryl co-enzyme A (HMG-CoA) reductase inhibitors, convert to mevalonic acid and become the rate limiting step in the hepatic synthesis of cholesterol.2,3 To decrease LDL and TG levels from the blood, the hepatic synthesis increases the number of LDL receptors located in the liver.2Although each medication has been proven effective when increasing HDL levels and reducing LDL, TG, and TC levels in the body, studies have demonstrated that simvastatin, fluvastatin, and pravastatin do not possess high enough efficacy rates when treating these contributors.4-11 Barrios et al,4 Tavridou et al,5 van Tits et al,6 and Jaco...

...ve stress [8] and can help combat many cardiovascular disorders, thus confirming the protective capabilities of nitric oxide. Another one of nitric oxide’s protective capabilities stems from its role as a potent vasodilator, and these vasodilation properties are primarily achieved through the activity of eNOS. eNOS is a membrane bound protein that is classified as a calcium-calmodulin dependent enzyme [13]. At resting concentrations of calcium, eNOS generates low amounts of nitric oxide, however, as intracellular calcium concentration increases, there is a potent enhancement of nitric oxide production by eNOS [13], which then goes on to cause vasodilation to prevent blockage of blood flow. Due to its generally low output, eNOS is largely associated with basal cardiac function, while iNOS is a much higher output enzyme, generating much more nitric oxide than eNOS [5].

An artery is an elastic blood vessel that transports blood away from the heart. There are two main types of arteries: pulmonary arteries and systemic arteries.
The CoQ10 stays in the mitochondria. This is the energy-generating component of the body cells. This coenzyme produces the ATP or adenosine-5-triphosphate. The ATP boosts protein synthesis and muscle contraction processes.
Atherosclerosis is a disease that occurs when arteries become blocked, inflamed, or hardened. As a result of this, blood cannot easily pass through the artery, and blood pressure increases. Many people suffer from atherosclerosis as they age, but young people can be affected by atherosclerosis also. There are many preventative steps that can be taken to decrease the risk of atherosclerosis; however, if atherosclerosis does develop in the arteries, medications can be given to help the individual receive adequate blood flow to important tissues. Atherosclerosis is a very serious condition that requires medical attention and a change in life style because it is a precursor to many dangerous and potentially fatal diseases.
Hypercholesterolemia is the presence of high levels of cholesterol in the blood. Cholesterol is a waxy fat-like substance and is a major class of lipid, so it gets into the blood by lipoproteins [1]. A high level of lipoproteins is unhealthy. A high level can result in an elevated risk of atherosclerosis and coronary heart disease [2]. The high levels of lipoproteins are often influenced by a combination of genetic and environmental factors such as obesity or dieting habits [2]. High cholesterol can be caused by mutations in the following genes: APOB, LDLR, LDLRAP1, and PCSK9 [3]. Mutations in the LDLR gene are responsible for causing familial hypercholesterolemia, which is the most commonly seen form of inherited high cholesterol [3]. The LDLR gene contains instructions for making LDL receptors or low-density lipoprotein receptors. LDL receptors play critical roles in regulating levels of cholesterol in the blood by removing low-density lipoproteins from the bloodstream. Mutations in the LDLR gene can make the amount of LDL receptors produced less than normal or affect their job of removing the low-density lipoproteins in the blood [4]. People who have these mutations will have higher levels of cholesterol. There are many ways that the environment can affect the levels of cholesterol in the blood. Reducing the amount of dietary fat you consume lowers the total amount of cholesterol in the blood [5]. Sucrose and fructose can raise the amount of LDL in the blood. Reducing fatty foods will however lower the amount of LDL [5]. Having a healthy body and maintaining physical exercise plays a key role in keeping your cholesterol at a healthy level. If you are overweight or obese you can lower your cholesterol levels by simply losing ...

It is the slowest working metabolic pathway for the production of energy in the body. This cycle, unlike the energy consumption in sprinting, allows the body to maintain its energy level during endurance activities. The citric acid cycle, or the Krebs cycle, allows humans to sustain long-term energy (long running) because it produces more energy than the other pathways. The Krebs cycle uses lots of enzymes, which reduce the amount of energy required for a chemical reaction. These enzymes help the body use less and create more energy. By using enzymes in the absence of more energy, the Krebs cycle is different from other metabolic pathways. Through the catabolism of fats, sugars, and proteins, an acetate is created and used in the citric acid cycle. The Krebs cycle converts NAD+ into NADH. These are then used by another system called the oxidative phosphorylation pathway to generate
CAD is a leading cause of morbidity and mortality throughout the worldwide. The prevalence of biological and metabolic risk factors were also found to be high in development of coronary artery disease. Patients with hypercholesterolemia are at increased risk to experience cardiovascular events and to die from vascular disease [2]. .Statins, among the most commonly prescribed drugs worldwide, are cholesterol let downing agents used to manage cardiovascular and coronary heart diseases and to treat hypercholesterolemia. Statin’s therapy ...
Atherosclerosis is the most common cause of CAD. Atherosclerosis is a progressive disease characterized by fat deposits in the arteries causing them to block the normal passage of blood. No one is quite sure how atherosclerosis develops. The plaque consists mostly of cholesterol, phospholipids and smooth muscle cells. They also reduce the size of the lumen of the affected artery which impairs the blood flow of this artery and later on could form a thrombus that will completely occlude the vessel. “Unfortunately, signs and symptoms of atherosclerosis usually don’t develop until at least 70% of an artery’s lumen has become obstructed. Angina is almost always the first symptom to appear.”(Journal: The killer behind CAD,2010). Modifiable factors that could prevent the occurrence of CAD include cigarette smoking, obesity, physical inactivity, atherogenic diet like diet high in cholesterol, use of contraceptive and hormone therapy replacement. “Women continue to ...
In order to understand what effects could result of creatine use, we must first explore what exactly creatine does in our body. Creatine is an amino acid which acts as a building block in the construction of proteins in the body. Muscle cells take the creatine and store it as energy for future use in the body. During intense exercise, phosphocreatine is broken down to creatine and phosphate, which is used to regenerate ATP. The remaining creatine in storage in the muscle cells may also increase the regeneration rate of energy after intense exercise. This serves as an extra boost of energy for young athletes. Currently, scientific studies indicate that creatine will boost an athletes maximum performance level by 5-8%. There is also evidence that leads sports nutritionists to believe that creatine can boost total energy output by 5-15%. At this point, it seems...

The tendency to build up high cholesterol may run in families, but extremely high levels are usually the result of a poor diet high in saturated fats and calories, along with little or no exercise. In some cases, high levels of cholesterol may be associated with undiagnosed medical symptoms such as diabetes or low thyroid function. According to the American Heart Association, there would eventually be a 50 percent lower rate of heart disease if Americans would lower their blood cholesterol levels by 25 percent. These statements find confirmation in a 1984 report done by the National Heart, Lung and Blood Institution on the results of a 10 year study. It showed that for every 1 percent of lowered cholesterol, the chances of a heart attack are lowered by 2 percent.

Creatine has been known to provide additional energy for your muscles. Our body has a compound called ATP (adenosine tri-phosphate), which is an energy-containing compound. The ATP reaction releases energy in the body very quickly. This is a good thing, especially during an intense work out, when your body needs the most energy. Carbohydrates can give you energy, but it comes at a slower pace. When the muscles are using ATP for energy, a chemical process occurs where the ATP is broken down into two simpler chemicals, ADP (adenosine did-phosphate) and inorganic phosphate. This process of ATP turning into ADP releases the energy, which ...
