Pathology: Myocardial Infarction
Name
University

Objectives
1. Discuss myocardial infarction and its pathogenesis.
2. Describe the sequence of changes involved in myocardial infarction.
3. List the major physiologic and morphologic complications of myocardial infarction.
4. Describe management of myocardial infarction.
5. Discuss patient teaching of myocardial infarction.
Definition
Myocardial infarction (MI), commonly known as a heart attack, is an irreversible necrosis of the heart muscle secondary to prolonged ischemia. This usually results from an imbalance in oxygen supply and demand, which is most often caused by plaque rupture with thrombus formation in a coronary vessel, resulting in an acute reduction of blood supply to a portion of the myocardium. (Zafari, 2011)
Etiology
The etiology of MI is predominantly from atherosclerosis i.e. coronary artery narrowing due to plaque formation. Non-modifiable risk factors for atherosclerosis includes: age, sex, family history of premature coronary heart disease, etc. Modifiable risk factors for atherosclerosis includes: smoking or other tobacco use, diabetes mellitus, hypertension, hypercholesterolemia, hypertriglyceridemia, obesity, sedentary lifestyle and/or lack of exercise, psychosocial stress, poor oral hygiene, etc. Non-atherosclerotic causes of MI include the following:
• Coronary occlusion secondary to vasculitis
• Ventricular hypertrophy (e.g., left ventricular hypertrophy, idiopathic hypertrophic sub-aortic stenosis [IHSS], underlying valve disease)
• Coronary artery emboli, secondary to cholesterol, air, or the products of sepsis
• Congenital coronary anomalies
• Coronary trauma
• Primary coronary vasospasm (variant angina)
• Drug use (e.g., cocaine, amphetamines, ephedrine)
• Arteritis
• Coronary anomalies, including aneurysms of coronary arteries
• Factors that

They perform autopsies, write out autopsy reports, look over victim's medical records, and interview the victim's next of kin. They also have to be trained in the legal system and to be able to testify in court cases involving death or injury (“Forensic Pathology,” 2009). Most forensic pathologist start as a resident, then after residency they awarded the title medical examiner. They can continue working to deputy chief medical examiner and the top position chief medical examiner. It takes between 13 to 15 years of education to become a forensic pathologist.

A Career In Forensic Pathology

...Forensic pathology is a special area of pathology. After death occurs, a forensic pathologist would provide valuable information about the manner of death after an autopsy is completed. The autopsy reveals more than just the manner of death, but also the cause, where, when, and how aspects of the death occur. According to Igor Tsimberg, a Forensic Pathologist, that’s employed at the Hospital of the University of Pennsylvania, there are four different manners of death, with an exception for the unclassified manner, homicide, suicide, accidental, and natural deaths. But sometimes there are suspicious deaths, sudden deaths and unexpected deaths that occur with people. Many people do not realize that about half of the deaths examined by the forensic pathologist are natural death occurring without injury. Tsimberg mentions, that a Forensic pathologist can also be used...

Forensic Pathology and Miscarriages of Justice: a Journal Article Analysis

...Forensic Pathology and Miscarriages of Justice: a Journal Article Analysis Merlyn Arostegui Prof. Sigal CRJU 443 | Forensic Pathology and Miscarriages of Justice: a Journal Article Analysis The article chosen for analysis is titled “Forensic Pathology and the Miscarriage of Justice” written by Michael S. Pollanen of the Centre of Forensic Science and Medicine, University of Toronto in Toronto, Canada. The article was published in Forensic, Science, Medicine, and Pathology in 2012. The main purpose of the article was to present the fact that in order for the criminal justice system to operate in a safe and fair manner, any evidence presented in the duration of a prosecution must be accurate and objective—especially medical evidence. If either the accuracy or objectivity of evidence presented is compromised, there lies the possibility of unsafe prosecution which can lead to wrongful convictions or other forms of miscarriages of justice. Main Purpose There has been an increased awareness in the number of cases that have experienced a miscarriage of justice due to compromised medical evidence being presented during trial. Although there are legal tools available to regulate the types of evidence admissible in court as well as the “experts” allowed to present said evidence [such as Daubert hearings], these tools are only partially effective because forensic pathology is a discipline that grows and develops over time. The accepted view in pathology [or any field of science...

...on body fluids. For instance, together with clinical lab technologists, pathologists work to ensure that blood and blood products are safe. In microbiology, pathologists identify microorganisms that can cause infections – bacteria, viruses, fungi, and parasites – so that the most effective treatment can be selected for each particular case. An anatomic pathologist assists surgeons during operations by providing immediate diagnoses on biopsies (specially treated tissues removed in surgery and rushed to the lab). A forensic pathologist uses lab science to answer questions about evidence collected for criminal and civil cases.  Other pathologists conduct research in pathology, developing new tests and new instruments to better diagnose diseases. Some pathologists devote their careers to research in pathology, developing new tests and new instruments to better diagnose diseases. Pathologists often teach their specialty to medical students and those preparing for other laboratory professions, including clinical lab technology and cytotechnology, among others.

Forensic Autopsy

...Forensic Autopsy Name Institution Course Date Deaths resulting from blunt force trauma are the most common cases in forensic autopsy. However, it is imperative to note that some factors contribute to the actual death of the victim, leading to a contradiction of whether the cause of death was sharp force or blunt trauma related. For instance, a patient hospitalised after having had a car accident and died three weeks after hospitalization, having caught pneumonia would likely give the results that the patient died out of pneumonia. However, such is not the case. In the forensic autopsy, the cause of death should be categorised as blunt force trauma, categorically belonging to the cause “accident” (Prahlow, 2010). Therefore, because of the contradictions that occur in such autopsies, it is paramount to take note of the differences exhibited by blunt force trauma wounds and sharp force trauma injuries. Injuries caused by blunt force have the following characteristics. Firstly, blunt force inflicted wounds have abrasions on the skin epithelium. This arises as the result of the sliding force between the surface and the blunt objects, pressure or compression (Prahlow, 2010). Secondly, such injuries might show patterned abrasions, the phenomenon in which the wounds pattern is transferred to the intermediary between the skin and the blunt object, such as clothes. These forms of wounds can be used to identify weapons as the sources of blunt trauma injuries...

Autopsy

...The Conventional Autopsy still has an Important Role in Modern Medicine RACHNA BAJAJ INTRODUCTION Human dissection has historically been carried out in search for humours, worms, miasmas and divine spells to explain what caused illness and death. However, as ‘scientific’ thinking advanced, there was a desire to understand disease based on the empirical evidence obtained from post-mortem examinations.1 This gave birth to one of the most important gold standards of diagnosis, a great tool for medical audit and probably the best teaching method of medicine – the autopsy. The words ‘autopsy’, ‘necropsy’ and ‘post-mortem examination’ are synonymous with each other and refer to the investigation of the human body involving an external examination followed by the dissections of the head, thorax and the abdomen. The word autopsy literally means ‘to see for oneself’. Autopsy rates in the United Kingdom (UK) currently stand at 21.9%, out of which only 0.4% are not requested by a coroner and the most common request for an autopsy occurs in cases of unexpected deaths where the cause is not apparent. Autopsies are also carried out for determination of manner of death, evaluation of ante-mortem and post-mortem diagnosis, epidemiological purposes, survey outbreaks, medical audit, research, teaching, forensic purposes and to enlighten/reassure families or inform then of hereditary diseases. Despite the well-recognised importance of autopsies in twenty-first century medicine...

Pancreatic Cancer

...Just like any other disease, pancreatic cancer must be diagnosed by a physician by doing certain tests and procedures to make sure they are diagnosed correctly. Most patients initially go to the doctor with common symptoms that may turn out to be any number of diseases that a physician has come to educate themselves about. An initial physical exam is usually followed up with things such as blood tests, x-rays or an ultrasound. If the physician were to determine that things did not look normal in one or all of these tests, a CT or computed tomography scan will be ordered. Abnormalties on a CT scan will be followed up with a biopsy to make sure a proper diagnosis is made. There is a certain blood test that can be done to help diagnose a patient with pancreatic cancer. It is called the “tumor marker” test and is also often referred to as CA 19-9. This marker is usually found in the blood of those patients with pancreatic cancer, but can also be found in patients without pancreatic cancer and those with benign conditions. This is not always a definitive way to diagnose pancreatic cancer, as the blood levels in some patients can be normal when they do in fact have pancreatic cancer. A biopsy consists of tissue that is taken from the body so that a pathologist can look at it closely. Abnormal tissues in the body may be referred to as lesions, tumors or masses. To obtain a biopsy of abnormal cells that may be on or around the pancreas, an invasive procedure would have to be done...

I have been pursuing this dream since my freshmen year. I found so many interesting, shocking, and yet some upsetting things. I realized that not everything is positive when it comes to choosing your career. When actually seeing, physically what Forensic Pathology really is, you’ll be shocked about it. Since reading about it and actually doing the job, it’s so different it never crossed my mind that it would be so much work. There are many steps to becoming a Forensic Pathologist. The education for it takes many years, but yet it is possible. A forensic pathologist (which is known to most people as a medical examiner), is heavily involved in the criminal justice system and medical system. The medical examiner's main job is to conduct an autopsy on the victim of any unnatural form of death. Their primary task in potential criminal cases is to find the cause of death and confirm if it was homicidal, suicidal, or an accident. They perform autopsies, write out autopsy reports, look over victim's medical records, and interview the victim's next of kin. They also have to be trained in the legal system and to be able to testify in court cases involving death or injury (“Forensic Pathology,” 2009).

...Diagnosis means the primary dysfunction toward which the physical therapist directs treatment. The dysfunction is recognized by the physical therapist based on information obtained from the history, signs, symptoms, examination, and tests the therapist performs or requests. Clinicians implement strategies that predominantly involve the use of exercise and physical agents to change or prevent circumstance that affect patient’s life style. Choosing the most useful and least harmful strategy for a given patient is one of the clinical decisions made by the clinician daily. Establishing a physical therapy diagnosis allows the clinician to name and classify clusters of symptoms, signs, and demographic data of similar patients who have responded successfully to a specific treatment. Using the systematic process of classifying clinical data, developing categories based on the classification process, and naming categories of successfully treated patients increases the probability that the clinician will replicate or surpass the best
results obtained in previous situations. Physical therapists thus must establish diagnostic categories that direct their treatment prescriptions and that provide a means of communication both within the profession and with other practitioners and consumers about the conditions that require their particular expertise for effective treatment and prognostication. Additionally, for professional credibility, physical therapists must refrain from using diagnostic...

...What Is Cultural Anthropology? When a person thinks about cultural anthropology, they should not limit themselves by thinking of one particular thing. Their mind should be racing with countless subjects. ‘Cultural anthropology’ is a pretty broad title for a discipline that covers such a wide range of topics. Anthropology studies all that is human and all that makes us human (Malloy, 2011). To narrow it down a bit, anthropology studies culture. One can define culture as “those relationships whereby, one and one’s community establish identity; knowledge of self and others, knowledge of the world and how we are to be in the world, and what various versions of those worlds mean to ‘us’ and ‘them’” (Malloy, 2011). Every individual person represents a culture of their own within the society they live in. Jack Weatherford estimates that “the globe stands divided into roughly two hundred independent countries or states, but these contain somewhere around five thousand different nations or ethnic groups” (1994, p.226). With so many different cultures out there, people of a particular society cling to their culture and hold to it with extreme importance. Even through times of modernity that pushed for a world culture, the number of different cultures did not homogenize and mesh together. On the contrary “ethnic and cultural identities grew stronger…and accentuated differences to become more varied than ever” (Weatherford, 1994, p.8). Cultural anthropology studies that behavior and the...

...What is it? This article provides an overview of how small hospitals can maximize resources. Why is it important? Small hospitals must compete vigorously to attract and retain physicians. How do I use it? Read this and look for new articles through CAP TODAY. It’s a Small World: Making the Most of Modest Means By Karen Southwick When a laboratory instrument breaks down at Marian Medical Center, on the central coast of California, staff members roll up their sleeves to fix it because the nearest repair facility is three to four hours away, which means at least a day’s turnaround. "We have to be very good at repairing instruments ourselves and doing on-site and preventive maintenance," says Nancy Felton, laboratory manager at Marian, a 167bed hospital in Santa Maria, Calif., about equidistant from San Francisco and Los Angeles. Consequently, reliability and user-friendly maintenance and repair are key criteria in the hospital’s purchase of new or replacement instruments. "We want to be able to deal with most problems ourselves," Felton says. Marian Medical Center and other small hospitals (under 200 beds) share similar labmanagement problems: When considering new tests, these labs must justify not only the cost of the equipment, but also the space and training resources they will consume. Turnaround time and volume are also important factors. 1 Practice Management Toolkit © 2011 College of American Pathologists. All rights reserved. At the same time, small hospitals...
