Summary
Case Study: Myocardial Infarction Pathophysiology Myocardial infarction occurs as a result of imbalance between the demand and supply of oxygen to the muscles of the heart that is critical enough to result in necrosis of the myocardium. This occurs due to rupture of a plague in coronary artery leading to sudden reduction of blood supply to the portion of myocardium supplied by the coronary artery…

Download file to see previous pages When a portion of myocardium is affected thus, the function of the whole heart is affected resulting in blood supply to other parts of the body like brain and vital organs (Fenton, 2008). This leads to multiorgan dysfunction. Arteries that supply the muscles of the heart are known as coronary arteries. These arise from the aorta and lie on the surface of the heart. There are 2 main coronary arteries, namely the right and left coronary arteries. The right coronary artery supplies the right ventricle and the left one supplies the lower parts of the heart. Most of the left ventricle is supplied by left anterior descending coronary artery. The circumflex artery supplies the back portion of the left ventricle (Zevit, 2006). Atherosclerosis, which results in coronary artery plagues is the most common cause of myocardial infarction. Other causes of myocardial infarction are respiratory failure, profound anemia, cocaine abuse, carbon monoxide poisoning, anamolous coronary artery and coronary artery vasospasm (Fenton, 2008). Risk factors for myocardial infarction are advanced age, smoking, sedentary lifestyle, male gender, abnormal lipid profile, hypertension, diabetes mellitus, family history of ischemic heart disease and hypertension. Compensatory mechanisms Physiological response to myocardial infarction include increased heart rate, increased mean arterial pressure, increased respiratory rate and raised serum cortisol levels (Cherrington et al, 2002). Medical treatment The goals of treatment in a patient with myocardial infarction are to restore oxygen supply to the heart, to prevent worsening of ischemia, cause relief of pain and finally to prevent and also manage various complications related to myocardial damage. Treatment of patient diagnosed to have myocardial infarction includes oxygen administration, aspirin, sublingual nitrate, betablockers and pain relief using morphine. Administration of aspirin in the prehospital phase or even after immediate arrival to the hospital has shown to decrease mortality and chances of reinfarction. Those allergic to aspirin must be administered clopidogrel. Sublingual nitrate decreases preload and also decreases paon. However, this drug must not be administered in right ventricular infarction and hypotension. Betablcokers decrease the heart rate and hence decrease the oxygen demand of the myocardium. Morphine decrease pain and thus demand of oxygen. Further treatment depends on the type of infarction (Fenton, 2008). In STEMI, immediate reperfusion therapy must be initiated and this includes either percutaneous coronary interventions or thrombolytic therapy. NSTEMI patients must receive antiischemic treatment along with percutaneous coronary interventions. Reperfusion therapy must be started immediately in STEMI patients. Percutaneous coronary interventions are better than thrombolytic therapy (Fenton, 2008). These are done after angiogram. Adjunctive intravenous heparin therapy is given for maintenance of patency of the arteries (Fenton, 2008). The patient under discussion was given aspirin, heparin, Vitamin E,B and D and protonix. Protonix is proton pump inhibitor and it is give in conjunction with aspirin therapy because of risk of gastrointestinal complications following aspirin therapy.

Myocardial Infarction

...Myocardial Infarction Introduction. Myocardial infarctions or acute myocardial infarction (MI) is commonly called heart attack and is a serious disease of coronary which occurs due hardening or narrowing of arteries when cholesterol plaque builds up. Blockage of arteries leads to a major reduction of blood supply, consequently causing necrosis (death or damage) of heart muscles (myocardium) or myocardium ischemia as the heart muscles are not served with oxygenated blood for quite some time (Life nurses forum:Nursing care plans for Myocardial infarction (MI)) (Imagins website:The women health resource,Overview of myocardial infarction.). The infarction site depends on which vessels are involved. For example, if blockage occurs... in...

Myocardial Infarction

...Myocardial Infarction Heart is the most vital organ in the body. It is the muscular pump that supplies blood to every organ and tissue to sustain life. Its own blood supply is however critical to life. The adequate function of heart depends upon the balance between its own metabolic demand and the supply of blood. An imbalance in this predisposes the heart muscle to ischemia, which means reduced blood flow. The tissue death as a result of ischemia occurs because of two reasons, reduced oxygen supply and the decreased delivery of nutrients, both of which are brought in by the flow of blood though the heart muscle. The area deprived of blood supply is said to have suffered ischemic injury. The ischemic...

...? Myocardial Infarction Article one Myocardial infarction accelerates atherosclerosis Summary This article gives a report on the effect of myocardial infarction on atherosclerosis. The results are based on research information obtained from the use of mice in the investigation. As atherosclerosis progresses toward the acute stage, it triggers myeloid cells destabilization in the artery walls which makes them rupture. This cause stroke and infarction. This research shows that the response to ischemic damage makes acute atherosclerosis to get worse. The mice used in this experiment were reported to have larger and more...

Obstructive Uropathy and Myocardial Infarction

...Obstructive Uropathy and Myocardial Infarction in the Clinical Case: Pathophysiology Related to Clinical Case and How these Two Diagnoses Affect Each Other Introduction: Obstruction to the flow of urine, with attendant stasis and elevation in urinary tract pressure, impairs renal and urinary conduit functions and is a common cause of acute and chronic renal failure. With early relief of obstruction, the defects in function usually disappear completely. However, chronic obstruction may produce permanent loss of renal mass. and excretory capability, as well as enhanced susceptibility to local infection and stone formation. Early diagnosis and prompt therapy are therefore essential to minimize...
