Myocardial Infarction Case study Essay (Critical Writing).
Coronary artery disease. Coronary Artery Disease. Coronary Artery Disease, or CAD, is the single leading cause of death in the United States, accounting for over 900,000 deaths annually. More estimates show that over 3 million Americans suffer from occasional chest pains due to coronary artery blockages.
It is estimated that 15. 4 million Americans possess coronary heart disease, thus, making them seven moments more likely to have got a myocardial infarction than the general population(1). The annual chance of myocardial infarction can be estimated to become 715, 500, with around 29% of the being ST-segment elevation MI (STEMI)(1).
According to Kumar and Cannon (2009), ST-segment elevation myocardial infarction (STEMI) can be diagnosed if the ischemia causes myocardial damage. According to SAAS (2013) guidelines, chest pain that radiates to the jaw should be considered cardiac ischemia unless an alternative cause is obvious.
Acute coronary syndrome. Acute coronary syndrome compromises myocardium, a common cause of death in US and Europe. Myocardial infarction (heart attack) and unstable angina are its constituents resulting from sudden reduction in blood (oxygen) supply to the cardiac muscles.
Pathophysiology of Myocardial Infarction. The pathophysiology entails the entire process of what causes a myocardial infarction and how it eventually happens. As mentioned earlier, the most common etiological factor is the presence of an atherosclerotic plaque in the region of the coronary arteries.
Eventually a blocked coronary artery stops oxygen transfer to the heart and causes myocardial infarction.. Between the years of 1999 and 2000, the death rate from coronary heart disease declined 25%, and it is still slowly but steadily decreasing.
Coronary Heart Disease Coronary heart disease occurs when the coronary arteries become partially blocked from, cholesterol and fat, circulating in the blood. This causes a build up inside the walls of the arteries. This only occurs if the levels of fat and cholesterol are extremely high in the blood.
