hypertension‚ and what you can do to lower your blood pressure. Hypertension is a chronic medical condition where the pressure of blood in the arteries is elevated. Blood pressure is a measure of the force that blood pumps against the walls of the arteries‚ and will have two readings: the systolic pressure or the measure of the blood within the artery when the heart muscle is contracting‚ and the diastolic pressure or the pressure of the blood when the heart muscle is relaxing. It is read as systolic

surgery‚in which your chest gets crack open‚ to be able to treat block arteries. However‚ an open heart valve surgery will be done without opening the chest which minimizes invasion. This surgery replaces the valve is a new artificial or prosthetic valve. The incision is near the breastbone or right chest muscle. The quintuple bypass surgery corrects the condition known as coronary arteries disease‚ in which the coronary arteries are severely blocked‚ making it difficult for blood to get to the heart

layers of the wall of the carotid artery in your neck. Although this is not the same as examining your coronary artery‚ studies of thousands of patients worldwide have shown that the thickening of the carotid artery or the actual presence of plaque can indicate the risk of atherosclerosis‚ heart attack‚ and stroke. Coronary Calcium Scoring In a coronary calcium scoring test‚ CT scans are taken of the heart to detect the amount of plaque on your coronary artery walls‚ which can block blood flow

Title of research project: Smoking can be a contributory factor to cardiovascular and respiratory diseases. Aims and objectives of the research project: The aim of this research project is to prove the case that cigarette smoking has a detrimental effect on the health of the human body and can be a contributory factor to respiratory and cardiovascular diseases. Objectives: 1. Outline the compounds that make up cigarettes. 2. Explain how these compounds react in the human body

of a sphygmomanometer should be placed on the upper left arm. Using a hand held Doppler‚ the probe should be placed below the lower edge of the cuff‚ over the bifurcation of the brachial artery. 3. The cuff should be inflated beyond the expected systolic pressure in order that the pulse disappears as the artery is closed by the pressure and the blood flow stops. Listening carefully to the Doppler‚ the cuff should be deflated slowly. The systolic pressure occurs as the heart is at the height of its

high blood pressure. Blood pressure is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. Blood pressure is usually read 120/80. The top number is called the systolic blood pressure‚ which is the force of blood in the arteries as the heart beats‚ and the bottom number is called the diastolic blood pressure which is the force of blood in the arteries as the heart

deprived of oxygen rich blood. Angina isn’t a disease‚ it is a symptom of an under lying heart problem. People usually get angina when they are diagnosed with coronary heart disease. This is when plaque builds up on the walls of the coronary artery. You need these arteries open to supply the heart with oxygen rich blood. There are three types of angina. There is stable‚ unstable‚ variant‚ and microvascular angina. Stable angina is the most common type‚ it occurs when a heart is working harder than usual
