4.0 Aetiology Scientists continue to research into the causes of coronary heart disease however‚ their has been limited new research into the aetiology. Therefore‚ the causes of atherosclerosis will be discussed as well as other diseases leading to coronary heart disease such as transient ischemia‚ coronary stenoses and lifestyle factors. 4.1 Atherosclerosis Coronary heart disease is commonly caused by a buildup of plaque which narrows the arteries and reduces blood flow causing platelets‚

Problem Coronary heart disease is a chronic disease in which plaque‚ fatty deposits‚ builds up inside the coronary arteries which supply blood to the heart. The build up of plaque is called atherosclerosis and can develop for many years undetected. Some common symptoms of coronary heart disease are chest pain‚ shortness of breath‚ and extreme fatigue with exertion‚ in turn increasing the risk of other health issues such as angina pectoris and eventually heart attacks. Today‚ coronary heart disease is the

Heart Dissection Practical Report. Introduction On the of July 2002‚ a sheep’s heart was examined by dissection. The heart is a muscle in all mammalian bodies that is used to pump blood and nutrients throughout the body. A sheep’s heart was used in this prac because like the human heart it has four chambers and is similar in size. Two of these chambers are receiving chambers called the left and right atrium. The other two are pumping chambers called the right and left ventricle. The reliability

Every day your heart pumps blood through a vast network of blood vessels around and around your body‚ delivering food and oxygen to cells and removing waste. The pulse (heart rate) is the number of times a person’s heart beats per minute (bpm). The pulse is a rhythmical throbbing of the arteries as blood is propelled through them‚ typically felt in the wrists or neck. Your resting heart rate occurs when you become relaxed or comfortable. These are shown when sitting or lying down. The ability to

A heart attack can happen if the heart cannot get enough oxygen or if the flow of blood is blocked. Congestive heart failure a serious condition in which the heart is unable to pump enough blood supply to the body. Arteries can harden which causes the heart and kidneys to work harder. Impaired vision high blood pressure can cause blood vessels in the eyes to burst or bleed. Vision

whether alcohol and caffeine has an effect on heart rate‚ using the freshwater crustacean‚ Daphnia magna‚ as the experimental subject. For humans‚ alcohol works as a depressant‚ slowing down the heart rate of the consumer; caffeine works as a stimulant‚ increasing the heart rate of the consumer. The heart depends on an internal pacemaker system to keep it pumping consistently and at the right speed. Alcohol disturbs this pacemaker system and causes the heart to beat irregularly. Studies show that caffeine

Heart attack symptoms in men and women What is a heart attack? Heart attack is the death of a segment of the heart due to a blockage in the coronary arteries by a blood clot. Coronary arteries are blood vessels that supply the heart with nutrients and oxygen. Heart attack takes about 8-hours to be complete. During a heart attack symptoms just last for about 30 minutes. Heart attack can be diagnosed when there’s a severe chest pain and tests such as the cardiac enzyme test‚ electrocardiograph‚

Rheumatic Fever! Rheumatic Heart Disease By Kaya Michaelis Causes: Rheumatic heart disease is damage of the heart’s valves caused by rheumatic fever‚ which is caused by streptococcal bacteria. A streptococcal infection is caused by strep throat or scarlet fever.The streptococcal infection may result in scarring of the valves‚ weakness of the heart muscle‚ or damage to the hearts pericardium. Rheumatic fever mostly affects children from the ages of 5 -15‚ and occurs approximately 14-28 days after

Coronary Heart Disease (CHD) is a disease in which waxy substance called plaque builds up inside the coronary arteries. These arteries are used to supply oxygen-rich blood to your heart‚ so if they’re continuously blocked up‚ it can be very dangerous. If the flow of this oxygen-rich blood is reduced or blocked‚ a heart attack can occur. It is the number one cause of death in the United States for both men and women and although this type of disease mainly happens at an older age‚ it can happen
