Heart Failure Heart failure is an ailment where the heart is not able to pump the required amount of blood to the body. Left-sided heart failure is described as when the heart cannot pump enough oxygenated blood to the body while Right-sided heart failure is when the heart cannot fill with the appropriate amount of blood.1 One or both of these may occur with heart failure. In the United States‚ 5.8 million people have heart failure and this number is continuing to grow.1 With the number of people

Effects of Raising Interest Rates If a central bank increases the base rate‚ this tends to increase all major interest rates in the economy. This means interest rates for both savers and borrowers will increase. Higher interest rates will have various economic effects: 1. Increases the cost of borrowing. Interest payments on credit cards and loans will be more expensive. Therefore this discourages people from borrowing and saving. People who already have loans will have less disposable income

Mortality rate is a measure of the number of deaths (in general‚ or due to a specific cause) in a population‚ scaled to the size of that population‚ per unit of time. Mortality rate is typically expressed in units of deaths per 1000 individuals per year; thus‚ a mortality rate of 9.5 (out of 1000) in a population of 1‚000 would mean 9.5 deaths per year in that entire population‚ or 0.95% out of the total. It is distinct from morbidity rate‚ which refers to the number of individuals in poor health

Congestive heart failure is the process in which the heart becomes in-able to maintain circulation for the requirements of the body at an effective rate‚ As the heart is one of the body’s vital organs‚ it plays an important role and has some degree of compensating mechanisms to balance the body’s needs with existing disease of the heart. Eventually when the heart is no longer able to compensate heart failure occurs; congestion will then follow‚ resulting in insufficient supply of blood to the body

Heart disease According to hrsonline.org‚ “In the United States alone there are 5 million people with a heart disease. Every year 350‚000 people die from a coronary disease.” A coronary disease (heart disease) is several conditions in which prevent the heart from completing its functions and affects the structures of the heart (heart.org 3). A few of these diseases are cardiomyopathy‚ coronary heart disease‚ hypertension‚ and tachycardia. These conditions are only a few of a hundred possibilities

Finding out you or a loved one has a heart murmur can be frightening. Anything that causes heart complications is frightening. A heart murmur is an extra or unusual sound heard during your heartbeat. Although heart murmurs are common and need to be taken seriously‚ they are often quite harmless. Heart murmurs are most common in healthy children who can possibly out grow the symptom. With normal tests‚ doctors can find out the cause of a heart murmer and help with the problem. There are many alternate

RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts
