Describe what is happening when a Person Suffers a Heart Attack Essay:
A heart attack is a condition that results from coronary occlusion and can have fatal consequences on the inflicted persons (Cortez, 2007, pg. 5). The fatal consequence of a heart attack results from arrhythmia or myocardial infarction. The fundamental cause of health deterioration in heart attacks is the inability of the heart muscles to meet the blood circulation requirements for the vital body organs like the brain, kidney, liver and lungs.
The onset of the heart attacks is chiefly associated with coronary atherosclerosis. Coronary atherosclerosis is a pathological condition that causes structural abnormalities of the coronary artery leading to the cardiac muscles’ abnormalities. The onset of a heart attack can also be linked to blood clots. When the blood clot flows into the coronary blood vessels, it blocks the blood flow to the surrounding heart tissue.
Restriction of blood supply to the cardiac tissue by the blood clots and coronary atherosclerosis causes the heart to lose its blood supply. This point is the first stage of the heart injury. First, the heart muscles lose the supply of the basic nutrients. Additionally, the metabolic wastes of the cardiac cells accumulate because of the lack of perfusion. Moreover, the oxygen supply to the cardiac tissue is cut (Cortez, 2007 pg. 11-17). These events promote the loss of the metabolic activity of the cardiac muscle involved. In fact, the events promote the death of the muscle segment that is involved. The presence of the blocking agent in the coronary artery results in the death of the affected muscle. Such muscle injury results in myocardial infarction. The size of the affected muscle depends on the size of the blocked blood vessel; hence a large clot causes a large myocardial infarction.
Medicinenet.com says that, during this stage of heart attack, the affected individual experiences intense chest pain that lasts long and increases with damage of the tissue. The level of myocardial injury also depends on the length of time between the onset of the disease and the treatment. In the extensive injuries, the affected person may lose his or her life, especially if treatment is not provided.
Delayed treatment of the heart attack leads to the development of serious complications. One of the major serious complications associated with heart attacks is a stroke because of the reduced blood supply to the brain. Persistent cardiac arrhythmias also follow serious heart attack cases. Also, a heart attack victim can develop heart failure as a complication (Cortez, 2007 pg. 11-17). Other complications of heart attacks include blood clots formation and aneurysm.
Most people survive the myocardial infarction. After surviving the heart attack, the heart tissue may develop a scar or remain as a dead part of the heart. These aspects determine the victim’s quality of life and their longevity after the disease. This is because the heart may suffer from interrupted electrical activity leading to irregular cardiac rhythms. The survivors may also experience consequential shortness of breath.
In conclusion, when a person suffers from a heart attack the cardiac muscle fails to get blood supply because of a blocked coronary artery. Coronary artery blockage results from blood clots or coronary atherosclerosis. The consequence of coronary artery blockage is the injury of the cardiac muscle leading to reduced blood supply to the brain, lungs and the death of the myocardial tissue. If a person survives the infarction, their heart develops scars that influence the kind of life the lead after recovery (Heart attack , 2014).
