In this abstract can defined the sustained end-range rotation as a pre-manipulative screening test tool that utilise to examine insufficiency of brain blood supply on crainocervical arteries as vertebrobasilar arteries and internal carotid arteries through three different neck positions.

are all problems that can proceed in the cardiovascular system. Arteriosclerosis is a circulatory disease that is caused by fat buildup‚ cholesterol‚ and or other substances in the artery wall. These things make the veins stiffen up and become narrow. Hypertension is an issue when a force of blood pushes against the artery walls over time. This can be caused by a high intake of salt‚ smoking‚ kidney disease‚ and/or other medical issues. This problem can lead to a stroke‚ heart failure or visual problems

supply to the brain is reduced‚ this deprives human tissue of oxygen. As a result the cells in the deprived brain tissue die. There are three main types of stroke: 1) ischemic stroke [due to a blocked artery‚ this account for 85% of all strokes]‚ 2) hemorrhagic stroke [leaking/bursting of an artery] and 3) Transient ischemic attack [temporary disturbance of blood flow to the brain]. The common risk factors for a stroke are obesity‚ inactivity‚ high blood pressure‚ smoking‚ diet‚ use of narcotics

MYOCARDIAL INFARCTION This term refers to the death of a certain segment of the heart muscle (myocardium)‚ usually the result of a focal complete blockage in one of the main coronary arteries or a branch thereof. The main cause of myocardial infarction is atherosclerosis in the coronary arteries. Refer to figure 70 for the pathogenesis of myocardial infarction. This event results in impaired contractility of the heart muscle within seconds‚ and is initially restricted to the affected segment.

your heart is blocked for a long enough time that part of the heart muscle is damaged or dies‚ this is called a myocardial infarction (MayoClinic‚ 2011). A heart attack occurs when one or more coronary arteries become blocked. This blockage is usually caused by build up of cholesterol in the artery (MayoClinic‚ 2011). The symptoms include pressure in your chest that last longer than a minute‚ pain that extends from your chest to your arm‚ increasing episodes of chest pain‚ prolonged pain in the

Cardiovascular disease is a common chronic illness in our society and it causes over half the deaths in the US each year. It affects all aspects of the heart. It affects the arteries that supply blood to the heart‚ the valves which pumps the blood and the heart muscles‚ itself. People who don’t take care of themselves can develop cardiovascular disease‚ which can cause heart attacks‚ congestive heart failure or strokes. A patient’s
