Cardiovascular Disease And Its Pathophysiology Essay
Cardiovascular disease accounts for the major health care problem and leading cause of death in the US. Based on the recent statistics from the CDC (2016), almost 610,000 Americans die of heart-related ailments. The prevalence of this disease is such that it dramatically increase the health care costs approximately $ 207 billion in a year (CDC, 2016).
In normal conditions, the heart pumps blood through the arteries and veins and follow a smooth pathway. This flow is in turn control by the sympathetic and parasympathetic nervous system (Huether, & McCance, 2012). Based on the body’s needs, heart pumps the desired amount of blood to maintain the tissue function. When this normal physiology is altered due to any heart diseases, an imbalance in supply and demand occurs in the heart. According to Huether and McCance (2012), the major pathophysiological events are due to the occlusion of major coronary arteries and resultant tissue damage (NIH, 2012). If the myocardium cannot withstand with the poor oxygen supply, a significant death of the heart muscles can occur within no time. In the acute myocardial injury, heart muscles may be deprived of oxygen for less than 3- 5 days. If this condition cannot be reversed, permanent infarct and heart failure occur and this can be fatal to the body (AHA, 2012).
Acute myocardial infarction according to Laureate Education (2012) is the cardiac event…
