Epidemiology

Epidemiology is the process of where one is able to study a disease or disorder. The public health department job is to conduct studies that are epidemiological in nature in order to prevent contagious disease from spreading. An epidemiologist is one who understands the rate/risk ratios, rate/risk differences, and measures the impact on the public.

Each epidemiologist deals in his own science and disciplines when he is taking these factors and measuring them. The discipline requires him to be able to select and use appropriate statistical methods in the analysis of simple data sets and apply these methods by computer using either STATA or EPI-INFO. He must also be able to understand and interpret output from statistical analyses carried out by computer, in relation to research and other questions asked. Then the epidemiologist must present findings based on statistical analysis in a clear concise manner.

The epidemiologist must be able to define a research problem and formulate a study hypothesis and objectives. He must choose an appropriate and ethical study design, plan field procedures, including sample selection, and the design of questionnaires and record forms. A time schedule for the conduct of the study is vital part. The need to prepare a budget is always important for this type of research. A detailed protocol that is of sufficient standard developed into a submission statement for a funding agency.

The epidemiologist must understand the basic statistical measures and concepts underlying the analysis of epidemiological data. He must perform analyses of data arising from epidemiological studies using appropriate computer software. He must be able to identify factors that suggest a disease has an infectious cause. He also must understand the factors determining the spatial, temporal and social distributions of communicable diseases. It is vital that the epidemiologist understand how to measure transmissibility of infections, design, and carry out, analyses, interpret and report an outbreak investigation report. It is of course very vital that the evaluation of vaccine efficacy be investigated.

The study of epidemiology and the use of an epidemiologist are vital for any nation’s health. This is very important for it helps our nation prevent major breakouts of diseases. I would like to say our people do an excellent job in this field and their tasks are not always easy but always necessary. The American Heart Association feels that since heart failure is the number one killer of men and women in America today that our Public Health Department is not fulfilling their duties toward heart related diseases.

In the above description of what epidemiologist, duties are and why we have the study of epidemiology gives a better understanding the medical field problems concerning heart failure patients. The AHA has gathered as much information as possible thru magazines and articles and made a journal for the doctors to refer themselves too. That journal is piece meal at best not complete and not adequate for the care and prevention of heart related problems. That is why we need an epidemiologist from our Public health Department to look at the situation.

Enjoy the Highest Quality of Life Possible With Congestive Heart

Enjoy the Highest Quality of Life Possible With Congestive Heart Failure

There is no doubt about it, cardiac complications can impact every corner of life, forcing patients to forego activities they previously enjoyed and causing them to feel as though they have sacrificed their life to save it. There are, however, many steps patients can take to allow them to enjoy life even after having been diagnosed with heart failure.

Congestive heart failure occurs when the cells of the heart are unable to constrict properly and pump blood through the body. This results in edema throughout the body, particularly in and around the lungs and is the cause of the dyspnea that is typical of heart failure. To counteract this, patients should take any diuretics prescribed by their doctor and maintain a low sodium diet, allowing the excess fluid to leave through the renal system and making it easier for the patient to breathe. Daily exercise is important; it is not necessary that it be vigorous, patients should consult with their physician prior to embarking on an exercise regime to ensure that they will not be taxing their heart unnecessarily. It is possible that if a patient has previously enjoyed activities that put a great deal of strain on the heart they will find it necessary to restrict themselves to less stressful endeavors; however, with the proper precautions many physical activities are still permitted.

The heart pumps blood more easily when the body is at rest; therefore, it is essential that patients with heart failure schedule time daily to rest. They may sit and read or watch television, take a nap or meditate; any activity that allows the body time to recharge. Meditation is being considered as a possible method of treatment for patients suffering from heart failure; meditation causes the heart to beat slower, blood pressure to normalize, the muscles to use oxygen more efficiently and the body to produce less adrenaline. All of these factors make it easier for the heart to function.

Any patient suffering from heart failure should abstain from smoking. Inhaling nicotine causes the body’s blood pressure and heart rate to increase, less oxygen to reach the muscles and an increased clumping and stickiness in blood vessels that may impede blood flow. All of these factors cause the heart to beat harder in an attempt to compensate, placing more stress on an already weak heart.

Patients should also avoid flu and pneumonia as much as possible, avoiding crowded areas during cold and flu season and receiving both an annual influenza vaccination and at least one dose of the pneumococcal vaccine (this will provide some protection against pneumococcal bacteria, the most common cause of bacterial pneumonia). The decreased oxygen in the blood resulting from either flu or pneumonia will result in the heart pumping harder in an attempt to compensate.

Everything in their life affects a patient’s well being when they are suffering from congestive heart failure, right down to their clothing. These patients should avoid restrictive clothing and stockings as much as possible, as these items present an increased risk for clotting and a blockage of blood to the extremities. They should also avoid temperature extremes as much as possible and dress appropriately for the weather; the body must work much harder to maintain temperature when it is either extremely hot or extremely cold.

The most beneficial thing that patients suffering from heart failure can do to allow them to enjoy their life is to enjoy their life. The negative effects of stress on the heart are well documented, and patients who live a stress free existence create a much better environment for their heart than those who are unhappy or overworked. So by maintaining a positive mental state, patients are able to help themselves both emotionally and physically.

Congestive Heart

A congestive heart can be fatal without the proper treatments. That is why today the government spends a lot of time and resources researching for cures and preventatives.
When you suffer from having a congestive heart then the heart is not able to maintain adequate circulation of blood in the tissues of the body or to pump out the venous blood returned to it by venous circulation. It is very important for all patients to understand what their heart is doing so they may take action to prevent any failure by the heart.

We do realize that you cannot see inside your chest and know what is going on but there are symptoms that will clue you into the fact that you are having some problems. All of a sudden, you notice that you have a shortness of breath whenever you try to walk or go up and down steps. This is one of the major signs of heart congestion.

All of a sudden, you realize that you tire easily and feel constantly tired even after a good nights rest. Fatigue and tiring is another signal that you should call your physician with concerns about your possibility of congestive heart problems. When you find the swelling of the feet, ankles, legs and occasionally the abdomen are constant and very discomforting then you should check with your doctor. Persistent coughing, raspy breathing or wheezing is another symptom of having a congestive heart.

“If you experience any of these symptoms, contact your doctor.”

Suddenly you find that you are gaining weigh and have no way of controlling this gain. When you diet but still find that you are gaining weight, perhaps the problem is with your heart. The fact that you are still gaining weight without any cause may have cause for alarm. This is a symptom of a congestive heart. Breathing can be come rather difficult even when you are lying down. A cough or wheeze may also occur along with spitting up red sputum. These are all signals of a congestive heart and you should see your physician before it becomes congestive heart failure.

You are really into problems if you have chest pain feel palpitations of the heart and develop a fever do not hesitate go straight to the emergency room as this is a signal that your congestive heart failure is happening. You might have started out with some ankle swelling, feet swelling and leg swelling at that point I would immediately contact my physician. I am sure that at this point your physician will send you to a cardiologist. A cardiologist is a heart specialist.

A heart specialist can make suggestions that will help you maintain a healthy life style and provide you with the proper medical care. A proper diet is essential in having a healthy heart. Medicine has improved over the years and so has procedures that your cardiologist will advise you. Congestive heart problems need not become a situation of heart failure.

What New Therapies for Treatment of Congestive Heart Failure?

Heart disease is one of the deadliest killers in the world to date. Congestive heart failure, a condition found secondary to many major cardiac diseases, possesses its own high mortality rate. Fifty percent of those diagnosed with congestive heart failure will die within the five following years. Scientists and researchers are struggling to understand the exact mechanisms of the disease, and to find a cure.

Congestive heart failure results as the cells in the heart die or become non-functioning due to an event such as a myocardial infarction (a heart attack) or ischemic heart disease. Whatever the cause, the heart is subsequently unable to pump blood adequately throughout the body, resulting in the blood pooling in the organs and fluid building up in and around the lungs as sodium is unable to be properly excreted, causing the dyspnea that is the classic symptom of congestive heart failure.

Clinical research is targeted at both the treatment of the disease and the possibility of repairing the damaged cells in the heart. Current research is underway to test new medications that would assist in vasodilation, as well as a calcium inhibitor that would not result in the higher incidence of cardiac arrhythmia seen with the medications currently on the market.

In the age of natural medicine, the power of the mind has been invoked in clinical trials to use meditation and relaxation techniques to combat the stress on the heart that can be the breaking point for patients with heart failure. Stress has been shown to negatively affect the body’s blood pressure, forcing the heart to work harder and placing an undue amount of pressure on an already weakened muscle. The theory lies in the belief that by learning to maintain a low level of mental stress the heart will be less stressed and therefore less likely to fail completely, and the patient can be given a better prognosis.

Alongside the return to natural, holistic methods of treatment is an incredible advancement in clinical technology that was not available twenty or thirty years ago. Scientists claim to have identified a set of altered genes that can make an individual more disposed to suffer from congestive heart failure and are using their current knowledge of genes and the benefits of gene therapy to attempt to reverse the effect. In addition, medications to tamp down on the genes’ activities, such as beta blockers and alpha-2 agonists are already available and being used in treatment programs.

Also being explored is the possibility of using stem cells, the body’s pluripotent progenitors, to assist in reparation of the damaged heart tissue. Clinical trials showed that patients suffering from congestive heart failure responded very favorably to an injection of their own stem cells into the heart, although the exact means by which this causes improvement is as yet unknown. It is suspected that these cells either facilitate the growth of new vessels in the heart or act as beacon, attracting the body’s own healing cells to the site of the damage and stimulating repair.

The possibility of actually growing healthy tissue from embryonic stem cells to be transplanted is also being explored, although the controversial nature of the use of embryonic stem cells due to the necessary destruction of the embryo makes this questionable in the foreseeable future. Scientists have determined that adult stem cells simply cannot provide an adequate number of new cells to meet the needs of patients who have suffered heart failure.

Heart failure is incredibly dangerous because the body cannot reproduce the dead tissue cells in the heart; however, with modern advancements it is the great hope of researchers everywhere to one day find a cure.
