Acute Myocardial Infarction - Essay Example The etiology of the disease is many-sided. Patients at higher risk for AMI include: Obese or morbidly-obese patients Patients with a previous history of one or more AMI's Diabetic patients Patients with depression Patients with a low exercise level Patients with a high total cholesterol, or a high LDL/HDL ratio There are a number of potential causes for AMI. The most prevalent include the following: Vulnerable plaque, which is estimated to occur in 35% of patients. This may have its origin in a general higher level of inflammation in a patient. Some patients encounter vulnerable plaque due to Chlamydia or other infectious causes (Madjid, 2007). Thrombus formation: this may occur due to injury, smoking or excessive drinking, which can tend to create scars in the medial and epithelial layers of the major cardiac arteries. Thrombus formation in other parts of the body, including DVT (deep vein thrombosis) may result in migration to the heart, causing an AMI. Plaque formation: This may occur (as demonstrated above) due to high circulating cholesterol, particularly LDL. Depression: There is some debate whether depression accompanies AMI, or vice versa. Pathophysiology of AMI This list is far from all-inclusive. As an example, patients with diabetes are much more likely to have one or more AMI's (Sulfi, 2007). The etiology is complex, however. Those with diabetes tend to have higher levels of renal insufficiency, thrombus formation and plaque formation. In addition, the general narrowing of arteries in insulin-dependent diabetes mellitus patients tends to make them more vulnerable to thrombus-induced AMI. A similar argument can be made for cigarette... There is clear evidence, which will be covered in this paper, of the positive impact of nursing and patient care interventions post-AMI, and the effect of lowering morbidity and mortality.Vulnerable plaque, which is estimated to occur in 35% of patients. This may have its origin in a general higher level of inflammation in a patient. Some patients encounter vulnerable plaque due to Chlamydia or other infectious causes (Madjid, 2007).Thrombus formation: this may occur due to injury, smoking or excessive drinking, which can tend to create scars in the medial and epithelial layers of the major cardiac arteries.

As an example, patients with diabetes are much more likely to have one or more AMI's (Sulfi, 2007). The etiology is complex, however. Those with diabetes tend to have higher levels of renal insufficiency, thr ombus formation and plaque formation. In addition, the general narrowing of arteries in insulin-dependent diabetes mellitus patients tends to make them more vulnerable to thrombus-induced AMI.A similar argument can be made for cigarette smokers. Their increased rate of thrombus formation is due to vessel injury, but other effects are co-related. Plaque formation is also elevated amongst smokers, which may result in greater susceptibility to thrombus-induced AMI.

Critically analyse and evaluate current research and literature Essay

Critically analyse and evaluate current research and literature relating to the significance of the presence and absence of ano-genital injuries in posr puberta - Essay Example Male have testosterone while female have estrogen and progesterone. The reproductive stage continues until old age both in male and in female and eventually these are the secondary sex characteristics and events of puberty. It is essential to remember that however, that it is the puberty that represents the beginning period of the reproductive system activity. (Marieb, 2002) The ano-genital area of the human body, sometimes referred to as â€Å"genito-anal† includes the anus and the genitals of both sexes. The genito-anal plays a vital role in pre-pubertal and post pubertal stages. Earlier, the certain part of the body is not taken into consideration unlike nowadays where certain diseases can de diagnosed through the examination of the anus and the genitals. The observations can also serve as indicators of the sexual abuse especially in women. Many of the characteristics of the ano-genital areas are further studied to show its significance in many other reproductive processes and development. The ano-genital areas of both male and female can be differentiated if these were abused or not. In pre-pubertal ano-genital area is most likely have the characteristic of none presence of warts, hematomas, and lacerations mostly in children. These are just some of the sign if the certain individual have been sexually abused. In post-pubertal stages, the ano-genital appears to be the opposite of that of the pre-pubertal. In female victims, bleeding and discharge in both genital and anal region are more visible. (Hobbs and Wynne, 1999) The ano-gential index (AGI) or the value of the distance between the anus and the genitals divided the body weight, is primarily the comparative tool between individuals (Barett, 2006). The ano-genital index is commonly used in boys who had been exposed in chemicals. Scientists believed that exposure to chemicals such as
