Atrial myxoma was first documented as a simple vascular growth in the heart by TW King in 1845. Now, over a hundred seventy years later, it can be describe as a benign tumor of connective tissue typically in the atrium. Although it possesses characteristic of cancerous cells and is generally included in cardiac cancer because of their similarities, it is often not considered cancer because it is benign. Heart tumors and cancers are very rare, accounting for only 0.2% of tumors found in the body, due to the fact that heart cells divide mostly while we are still fetuses. Once the heart is developed they divide less frequently leaving fewer opportunity for failure in the cell cycle. Because they are rare, there are still numerous unknown …show more content…
Overall though, atrial myxoma has a one in two thousand ratio of incidence and females of sex are more liking to be diagnosed by 75%. It is estimated that one in every ten occurrences are familial myxoma (hereditary) but this tends to be evenly distributed between sexes. These nicknamed “family myxomas” can even occur in multiple places of the heart at once but the patient tends to show symptoms at a younger age. In normal circumstances, generic symptoms are reported. Things like orthopnea, chest pains and tightness, dizziness, palpitations, and rapid weight loss are reported. For severer cases clubbing of fingers, bluish tents, fainting, and dyspnea are expected. Different symptoms can be associated with different locations of the myxoma. For example, in the left atria, more patients experience head pain and pulmonary edema with the myxoma, while in the right atria, they have greater symptoms of right heart failure. It has also been expressed that changes in body position and fast movements can bring on symptoms. Symptoms can be experienced in a few different ways. Some people report having them continually everyday whiles others come and
Cardiomyopathy, by definition, means the weakening of the heart muscle. The heart is operated by a striated muscle that relies on the autonomic nervous system to function. Cardiomyopathy is diagnosed in four different ways based on what caused the illness and exactly what part of the heart is weakened. The four main types of cardiomyopathy are dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, and arrhythmogenic right ventricular dysplasia. One other category of cardiomyopathy that is diagnosed is “unclassified cardiomyopathy.” Unclassified cardiomyopathy is the weakening of the heart that does not fit into the main four categories.
Genetic disorders can be caused by many of the 46 chromosomes in human cells. This specific disorder is linked to a mutation in the long arm of the X, or 23rd chromosome. The mutation is recessive, meaning a normal X chromosome can hide it. Females have two X chromosomes allowing them to hide the mutated recessive one, making them a carrier of the gene, while males only have one X chromosome, meaning that they are unable to hide the mutation and they become effected by the disease. Therefore if a male carries the gene, he is affected because he has no way of dominating the recessive gene, but if a female carries it, she is only a carrier and has a 50/50 chance of passing it on to her baby. This may seem like a high probability however, only one in every fifty thousand male births will have this immunodeficiency disease.
When the throat muscles are affected, this causes problems with speech, swallowing , and chewing. Patients may choke easily and their speech is often nasal due to the weakness of the velar muscles. The arm and leg muscles may weaken affecting activities like lifting or walking, with some patients appearing to wobble. There may be a loss of balance and an uncoordinated walk. It would be difficult to hold or grab on to objects with weakened arm muscles. Approximately 15% of MG patients have a thymoma. In most cases the tumour is not harmful and can be treated. Breath...

Spinal Muscular Atrophy affects about 8 out of every 100,000 live births and also causes death among more babies than any other genetic disease out there. About one in every forty people has this gene in them but may not have SMA so they are a genetic carrier. But in order for a child to have SMA, both parents have to carry the mutated gene and passed it to the child. Therefore this causes the child to have double copies of the abnormal gene. About 1 in 40 men and 1 in 80 women are carriers of the gene.

The most common symptoms of mesothelioma are difficulty in breathing, chest pain, or both. Occasionally, a patient may not have mesothelioma symptoms at diagnosis. Other less common symptoms include weight loss, fever, night sweats, cough, and a general feeling of not being well. Mesothelioma symptoms of peritoneal mesothelioma may include swelling, pain due to accumulation of fluid in the abdomen cavity, weight loss, and a mass in the abdomen. Other mesothelioma symptoms of peritoneal mesothelioma may include bowel obstruction, blood clotting abnormalities, lowered red blood cell count, and fever.
There are numerous risk factors for breast cancer. Genetics or family history of breast cancer in a one first-degree relative with breast cancer doubles a woman’s risk. Having two first degree relatives rises a woman’s risk by three times. A person’s personal history who have had one breast with cancer is three to four times as likely of developing a new cancer. White women are slightly more likely to develop breast cancer than are African-American women, but African-American women are more likely to die from this cancer. However in women under 45 years of age, breast cancer is more common in African-American women.
Coronary heart disease or coronary artery disease affects 16.8 million people in the United States and causes more than 607,000 deaths annually (Lemone, chap.30). It is caused by atherosclerosis which is the accumulation of fatty deposits in the arteries causing impaired blood flow to the myocardium. CAD or coronary artery syndrome is usually without symptoms but may induce heart attack, angina and acute coronary syndrome if not properly treated. There are many risk factors associated with CAD like obesity, high cholesterol diet, hereditary, physical inactivity, just to name a few. Patients with CAD may be unable to identify and manage their risks factors. It is imperative for nurses to educate the patient about CAD and measures to enhance their health.
Cardiac dysrhythmias come in different degrees of severity. There are heart conditions that you are able to live with and manage on a daily basis and those that require immediate attention. Atrial Fibrillation is one of the more frequently seen types of dysrhythmias (NIH, 2011). The best way to diagnosis a heart condition is by reading a cardiac strip (Ignatavicius &Workman, 2013). Cardiac strips play an chief part in the nursing world allowing the nurse and other trained medical professionals to interpret what the heart is doing. In a normal strip, one can clearly identify a P wave before every QRS complex, which is then followed by a T wave; in Atrial Fibrillation, the Sinoatrial node fires irregularly causing there to be no clear P wave and an irregular QRS complex (Ignatavicius & Workman, 2013). Basically, it means that the atria, the upper chambers of the heart, are contracting too quickly and no clear P wave is identified because of this ‘fibrillation’ (Ignatavicius & Workman, 2013).
Oxygen was first admitted to the client with chest pain over 100 years ago (Metcalfe, 2011). Chest pain is a large bracket that can contain many different conditions, but for the purpose of this analysis it is focused manly upon a myocardial infarction. A myocardial infarction is mainly referred to as a heart attack, and occurs when one or more coronary arteries leading to the heart reduce or completely stop blood flow (Tuipulotu, 2013 ). Administering high concentrations of oxygen to patients with chest pain is now embedded in guidelines, protocols and care pathways, even with a lack of clear supporting evidence (Nicholson, 2004 ). High concentration of oxygen means that up to 60% is administered (Knott, 2012). More recent research has suggested that the use of oxygen in this scenario is unnecessary and can lead to unwanted side effects, especially in normoxic cardiac patients (Moradkham & Sinoway, 2010 ). The aim of this comparative analysis is to dismantle and understand both the benefits and risks of the commonly known practice of administration of oxygen to the client with chest pain. Through completing this analysis using recent and appropriate evidence a more improved practice can be given and understood.
Symptoms that occur when a person contracts Myasthenia Gravis often begin with the drooping of the eyelids. Clinical Reference Systems (2010) state that as the disease progresses, blurred vision and difficulty in maintaining a steady gaze begin to happen due to further weakness in eye muscles. Face paralysis is common, as well as slurred speech and difficulty of breathing, chewing, or swallowing due to weakness in the face and throat. This often leads to gagging, drooling, or...
Different characteristics of tumours may point to malignancy in some organs but in other locations may indicate a benign growth. For example, Thieme indicates that “an echopenic halo suggests metastasis in the liver but suggests a...
The process of a drop of blood to go from the heart, to the body, and back to the heart is called the Cardiac Cycle. When the heart pumps blood throughout the body, there are a lot of factors that help it happen and influence how well it happens. It is a very quick cycle, occurring every .8 seconds, which means it happened about 70 times per minute. Systoles, diastoles, and blood pressure all are the main components of what make a cardiac cycle occur.
