How Doctors are Using Their Skills to Combat Congestive Heart

How Doctors are Using Their Skills to Combat Congestive Heart Failure

Congestive heart failure is an insidious opponent, possessing a slow onset that results in a patient often not even noticing they are having symptoms. Over time the patient will suffer from worsening dyspnea and edema that will eventually drive them to seek treatment, where they will discover that for whatever reason their heart is no longer able to function properly.

Heart failure occurs when the cells of the heart tissue are either destroyed or made non-functional due to another cardiac event, often secondary to ischemic heart disease or coronary artery disease. As a result, the heart is no longer able to pump the blood throughout the body properly; instead the blood pools, resulting in fluids being retained rather than excreted properly and oxygen starved organs being unable to function. The death of these cells is critical because, like brain cells, once the cells of the heart die the body is unable to reproduce them and restore full function to the heart. Congestive heart failure carries with it a high mortality rate, with over fifty percent of its victims dying within five years of being diagnosed. Doctors and researchers are able to use modern advancements in medicine to make the patient more comfortable and, in many cases, to provide them with a more favorable prognosis.

Many patients do not even discover that they have suffered heart failure until they are brought into the Emergency Department of their local hospital complaining of chest pain and difficulty breathing. Doctors will stabilize them there, giving them supplemental oxygen and beginning a course of medicinal treatment that will carry them out of the hospital.

Modern science has provided physicians with a wide array of methods with which to combat the damage done by congestive heart failure. Once oxygen is returned to an acceptable level a physician will usually administer a diuretic to stimulate the renal system to pull fluid out of circulation, relieving the edema and taking a great of stress off of the lungs, heart and other organs. This will also usually be accompanied by supplemental potassium, as the renal system will remove potassium along with the excess fluid and hypokalemia carries with it its own hazards.

A great deal of attention in the field of medicine has been focused on the body’s production of angiotensin II as it aggravates congestive heart failure. Angiotensin II is a substance produced by the body which raises blood pressure and causes the blood vessels to constrict, thereby forcing the heart to work much harder to pump blood throughout the body. An ACE inhibitor will often be administered to prevent the body from making angiotensin II, and an angiotensin receptor blocker is available to those who do not respond as desired to the ACE inhibitor. Many patients with heart problems are given nitroglycerin for this reason.

Along with medicine, research into the field of congestive heart failure is ongoing. The speculated use of stem cells, particularly embryonic stem cells, has opened a whole field of debate for possible treatment of heart failure in the science community. Patients with congestive heart failure were given some of their own stem cells in the heart via injection, and all reacted favorably. Scientists are unsure as to whether this is because the stem cells aid the body in growing new vessels or simply act as a lighthouse for the body’s natural healing mechanisms, drawing other cells to the site of the damage. Whichever the case may be, stem cells present a fascinating opportunity to finally find a means by which to restore heart function to patients who have suffered heart failure.

Modern science is providing a whole new world of treatment options to patients with congestive heart failure, and researchers are making new discoveries all the time. It is the hope of all of those in the medical field that one day heart failure will be another disease medicine has the answer to.

Psychiatric Evidence of Bipolar Disorder

Bipolar disorder, or manic depression, is a serious mental illness that has eluded doctors for decades. For many years, bipolar disorder patients were diagnosed as psychotic or Schitsophrinia. However, about twenty years ago, manic depression became a more common diagnosis. Psychiatric specialists still, however, did not really understand the illness.

Over time, more psychiatric evidence has come to light that proves that bipolar disorder, as it is now called, is actually caused by chemical imbalances in the brain. Other factors, both medical and situational, can be involved as well. In the last few years, psychiatric specialists and researchers have determined that bipolar disorder actually has varying degrees of severity, as well as types of symptoms.

Studies of bipolar patients conducted by psychiatric professionals and researchers has long suggested that bipolar disorder runs in families, or, in other words, is hereditary. Through careful study and research of the functions of the brain, it has now been determined how this illness is indeed hereditary and biological in nature.

According to research posted in the American Journal of Psychiatry in 2000, patients with bipolar disorder actually have thirty percent more brain cells of a certain class that have to do with sending signals within the brain. These additional brain cells cause patients’ brains to actually behave differently, making them predisposed to have periods of mania or depression.

According to researchers, this type of brain cell regulates moods, how someone responds to stress, and cognitive functions. When the extra brain cells are present, a congestion of cells regulated one type of mood or cognitive function is overloaded, and therefore causes a bout of mania or depression. It is not yet known by psychiatric researchers, however, why patients with bipolar disorder have these additional brain cells. To discover this, more genetic research will be required.

In addition to brain cells and brain chemistry, it has also been speculated by psychiatric researchers that various genes in the genetic makeup of bipolar patients can also contribute to the cause of and hereditary nature of bipolar disorder. Studies have been ongoing experimenting with removal of the gene in mice. The evidence suggests that circadian genes, which regulate mood, hormones, blood pressure, and heart activity may be linked to bipolar disorder. Specifically, the absence or abnormality of the gene actually seems to bring about mania episodes.

All in all, more research needs to be done. Medical and psychiatric researchers and doctors have a lot more to learn about the brain and how it functions. While current treatments seem to work for bipolar disorder, they also have severe side effects. Often, medications prescribed for bipolar disorder have to be monitored, dosages modified, or medications switched entirely for patients to maintain balance. The more we learn about the brain and it’s functions, the more we can learn about the physical, biological causes of bipolar disorder. The more we learn about the causes of bipolar disorder, the more likely it will become that effective treatments can be found that offer little side effects and more permanent treatment options for bipolar patients.

How do Physicians Treat Congestive Heart Failure?

Congestive heart failure is precisely what it sounds like; it is a failure of the heart to properly function, and its effects on the body can be devastating. Physicians do their best to treat the symptoms and give the patient the best prognosis possible; however, no true cure for congestive heart failure currently exists.

Heart failure occurs when the heart is unable to properly pump blood throughout the body; as a result, rather than distributing nutrients and oxygen to the tissues and then excreting the excess fluid into the urine the blood pools. This results in either a systemic or localized edema as fluid builds up in the veins and organs, causing swelling of the extremities as well as the organs themselves (this fluid accumulation is responsible for an excessive amount of stress on the heart as fluid accumulates in the pleural cavity as well as the dyspnea, or difficulty breathing, often symptomatic of heart failure). The swelling and lack of oxygen and nutrients will result in permanent damage to the organs if left untreated, providing a very poor prognosis for the patient.

The first stage of treatment generally consists of the administration of extra oxygen to attempt to return the oxygen levels in the tissues to normal. Once oxygen has been administered and a pulse oximeter reveals blood oxygen levels to be acceptable the focus will shift to attempting to treat the fluid build-up in the body. Diuretics will be administered to assist the excess fluid on its path out of the body via the urinary tract, and nitrates are administered to cause the vessels to dilate, allowing blood to flow more freely without the heart having to work quite as hard. Treatment with diuretics is often accompanied by supplemental potassium, as the body will excrete potassium in the urine and long term hypokalemia may result in muscle weakness or paralysis, as well as an increased risk of fatal cardiac arrhythmia.

Patients will often be sent home from the hospital with diuretics, as well as a medication known as an ACE inhibitor (an angiotensin-converting enzyme inhibitor) which prevents the body from creating angiotensin, a substance which raises blood pressure and causes the blood vessels to constrict. An angiotensin II receptor blocker may also be administered if the patient continues to produce angiotensin. Patients may also be treated with vasodilators other than ACE inhibitors, particularly if they have responded poorly to treatments with ACE inhibitors in the past. Nitroglycerin is a common example of this type of medication.

Digitalis, or Digoxin, may be prescribed to strengthen the force of the heart’s contractions, aiding it to push blood throughout the body. Treatment with a beta blocker is also beneficial in cases of heart failure, preventing the heart from beating more rapidly in an attempt to compensate for the poor movement of the blood in the body and placing more stress on the weakened muscle.

Blood thinners are used to prevent the formation of clots in the body that may be caused by the decreased movement of the blood in the vessels. Coumadin and heparin are the most commonly prescribed blood thinners in use today; however, due to an increased risk of bleeding patients taking these medications should undergo coagulation testing regularly.

Lifestyle changes are just as important as medications in the long term treatment of heart failure. Patients should consult with their doctor to establish an appropriate (low sodium) diet and exercise program, and should do at least some moderate exercise daily. Equally important is taking sufficient time to rest every day. The heart pumps more easily when the body is at rest, which is vital to an already overstressed muscle. The nicotine from cigarettes causes an increase in heart rate, blood pressure, and the tendency for clumping in the blood vessels; patients with heart failure should abstain from smoking. Flu or pneumonia can be very difficult for hearts that are failing as they attempt to compensate for the lack of oxygen in the bloodstream being carried to the organs. It is very important that patients receive an annual influenza vaccine, as well as a dose of the pneumococcal vaccine, which will protect them from the pneumococcal bacteria that cause over eighty percent of cases of bacterial pneumonia. Wearing non-constrictive clothing will assist in preventing blood clots and facilitating blood flow to the extremeties, and in cases of extremely warm or extremely cold temperatures it is important that the patient take all precautions necessary to keep the body at an appropriate temperature..

Researchers are still seeking to find a cure for congestive heart failure; however, until that day comes it is extremely important that patients suffering from heart failure follow the treatment plan outlined by their physician. With careful attention to maintaining their condition, the prognosis associated with heart failure increases dramatically.

Abscessed Teeth

An abscess in the tooth refers to an infection that was caused by a pocket of pus residing in the tissue around the tooth. Abscesses are very serious conditions, and can lead to serious matters if they arent treated immediately. When the pulp of a tooth dies due to damage or decay, bacteria will begin to grow from the dead tissue that is left. This bacteria will eventually spread from the root of the dead tooth into the tissue that is below and create a pocket of pus – the abscess.

Gum disease is also a cause for a tooth becoming abscessed. Gum diseases causes the gums to pull back and away from teeth, leaving pockets behind. When one of the pockets becomes blocked, the bacteria can grow and spread, or get backed up. When this happens, an abscess will start to form under the surface of the gums and become apparent will swelling as it gets bigger and spreads.

Once the infection has started to spread, your jawbone may start to dissolve as it makes room for the swelling in the area that has been infected. Once the bone starts to dissolve, the pressure will be greatly reduced, although the infection will still be there. Even though you will get relief, the infection will get worse – and the pain will always come back. Once more of the bone has been dissolved, there will be nothing left to support the tooth, meaning that it will become loose and end up needing to be extracted.

The symptoms of an abscessed tooth are easy to see, as they include severe pain in the affected area, red or swollen gums, a bad taste in your mouth, swelling around the area or the jaw, and possibly a high fever. Pain is excruciating with an abscess, normally affecting the area in a bad way. No matter what you do, the pain seems to intensify.

Abscesses mostly occur with back teeth, although they can happen in the front as well. Once your tooth has become abscessed, your dentist wont immediately pull it. If a tooth that has abscessed is extracted once the infection is still present, it can quickly spread. Your dentist will instead prescribe you some antibiotics that can help to destroy the bacteria.

The dentist can also perform a root canal, in an attempt to remove dead or decayed tissue. Last but not least, he can also drill a hole in the tooth to give the infection a chance to drain and try to remove any dead pulp. The most common treatment with an abscess is to use antibiotics to kill the infection, then get the tooth removed. You should never let it get that bad – as an abscess is something that can destroy your jawbone.
