Procedure to ventilate the lungs and artificially circulate the blood if the patient has stopped breathing and the heart has stopped beating. Mouth-to-mouth resuscitation involves forcing air into the victim's lungs; chest compressions pump blood through the heart.
Test to measure inflammation in the body. Inflammation from sites other than the cardiovascular system (such as inflammation of the gums or from a chronic urinary tract infection) can produce inflammation of the walls of the blood vessels. This can lead to blood clot formation and a myocardial infarction. The high sensitivity CRP test can detect lower blood levels of CRP and is used to predict a healthy person's risk of developing cardiovascular disease.
Pertaining to the heart and blood vessels
Combines two x-ray images, one taken without radiopaque contrast dye has been injected to outline the blood vessel. A computer compares the two images and digitally "subtracts" or removes the soft tissues, bones, and muscles, leaving just the image of the arteries.
(Digital Subtraction Angiography)
Procedure that records the electrical activity of the heart. Electrodes (metal pieces in adhesive patches) are placed on the limbs (both arms and one leg) to send the electrical impulses of the heart to the ECG machine. These are the three limb leads (leads 1-3). Electrodes placed on the chest are known as the pecordial leads(V1-V6). A 12-lead ECG records 12 different leads that show the electrical activity between different combinations of electrodes to give an electricle picture of the heart from 12 different angles.
Carries cholesterol to the liver where it is excreted in the bile. HDL is known by laypersons as "good cholesterol," and an increased level of HDL is beneficial.
Elevated blood pressure. Blood pressures above 140/90 mm Hg are categorized as hypertension, and the patient is said to be hypertensive. Several blood pressure readings are needed to make a diagnosis. (Hypertension)
Dilated jugular veins in the neck. This is caused by blood being backed up in the superior vena cava.
(Jugular Venous Distention)
The chamber on the upper left side of the heart.
The electrical impulses are unable to travel down the left bundle of His.
(Left Bundle Branch Block)
Cardiac enzyme found in many different cells, including the heart. The LDH level beginsto rise 12 hours after a myocardial infarction.
Carries cholesterol but deposits it on the walls of the ateries. It is known as "bad cholesterol".
Lower left chamber of the heart.
Battery- or pneumatic-powered pump placed in the abdomen and connected by tubes to the left ventricle and the aorta.
(Left Ventricular Assist Device)
Enlargement of the left ventricle
(Left Ventricular Hypertrophy)
Death of myocardial cells due to severe ischemia. The flow of oxygenated blood in a coronary artery is blocked by a blood clot or atherosclerosis. The patient may experience severe angina pectoris, may have mild symptoms similar to indigestion, or may have no symptoms at all(silent MI).
millimeters of mercury
Blood flows back into the left atrium with each contraction.
Nuclear medicine procedure that uses the radioactive tracer technetium-99m. First, pyrophosphate is injected intravenously to allow red blood cells to bind with technetium-99m. Then technetium-99m is injected. A gamma camera records gamma rays emitted by the technetium-99m bound to red blood cells. The camera is coordinated(gated) with the patient's ECG so that images of the heart chambers are taken at various times. A MUGA scan also calculates the ejection fraction . The ejection fraction is the most accurate indicator of overall heart function. This procedure is also known as RNV or gated blood pool scan. (Multiple-gated Acquisition)
Structural abnormality in which the leaflets of the mitral valve do not close tightly. This can be a congenital condition or can occure if the valve is damaged by infection. There is regurgitation as blood flows back into the left atrium with each contraction. A slight prolapse is a common condition and does not require treatment.
