A pressure measurement can be described as either static or dynamic. The pressure in cases with no motion is static pressure. Examples of static pressure include the pressure of the air inside a balloon or water inside a basin. Often, the motion of a fluid changes the force applied to its surroundings. For example, say the pressure of water in a hose with the nozzle closed is 40 pounds per square inch (force per unit area).
If the valves are damaged there is a growing risk of heart failure. Arrhythmia is another complication, because the heart's rhythms may be affected by endocarditis. As endocarditis is an infection, the infection itself can spread within the heart and to other parts of the body, such as the kidneys, lungs and the brain.
Risk factors for infective endocarditis are. 1  Birth defects of the heart, heart valves, or major blood vessels. 2  Heart valve damage due to rheumatic fever. 3  Degeneration of the heart valves that occurs with aging. 4  Intravenous injection of drugs using dirty needles. 5  A replacement heart valve.
