Heart Disease Approximately 610,000 American dies from heart disease each year (CDC, 2015). It is the leading cause of death in men and women; as well as for people of most ethnic/racial groups in the United States (CDC, 2015). African American are twice as likely to die early from heart disease, and men have the highest risk of early death with heart disease (CDC, 2015). The term heart disease refers to numerous cardiovascular diseases. Cardiovascular diseases are diseases of the heart and…

The dilated cardiomyopathy is a progressive and chronic disease of the heart muscles, the most common type of cardiomyopathies, occurring mostly in adults 20 to 60, more common in men, usually starting in the heart's main pumping chamber (left ventricle), the muscles of the heart starts to stretch and to become thinner leading consequently to enlargement inside the chamber of the heart and can spreads to the right ventricle and then to the atria (Bhf.org.uk, 2017). When the heart chambers dilate…

Wave Forms The P wave represents atrial depolarization. When the sinus node is in control, there should be a P wave for each and every QRS complex. Typically, sinus P waves do not plot through an ectopic from atrial tissue, since the premature atrial depolarization will reset the sinus cadence called a premature atrial complex (Blesi/Jones/Lewis pg136). The P waves is when the valves between the atria and ventricles open 70% of the blood in the atria and the atrial contraction is only…

Coronary artery disease (CAD) results when our body’s coronary arteries become damaged. Our coronary arteries are important because “they supply our heart with blood, oxygen, and nutrients” (Coronary artery disease, 2014). Our arteries typically get damaged because of plaque and inflammation developing inside them. “The buildup of plaque causes our arteries to become narrower and that decreases our blood flow to our heart” (Coronary artery disease, 2014). This decreased blood flow can cause…

commonly known as heart attack occur when blood supply is interrupted, causing damage or death of the heart cells. What causes the heart muscle to lose its blood supply? Usually, the loss of the heart's blood supply is caused by the total blockage of a coronary artery by a blood clot on a cholesterol plaque in the artery. Cholesterol is a fatty chemical which is a part of the outer lining of cells in the body. Cholesterol plaque is the formation of a hard substance within the walls of the artery…

recognize signs and symptoms when they occur. In order to improve the quality of life by decreasing the risk factors and increasing the prevention measures in the different patients that have a history of cardiac problems. Studies have shown that coronary heart disease (CHD) and stroke are the first and third most common cause of death in the United States. Both are the most common cause of disability in the United…

The Importance of Medical Knowledge Having basic medical knowledge is essential for survival and taking care of one’s self. Without this knowledge, people can infect each other mindlessly and cause themselves and others to be at risk. For instance, in the book The Ghost Map by Stephen Johnson, the majority of people living in that era were uninformed about the disease, cholera. People were in mass hysteria because they thought that the disease was caused by an odorless miasma. This caused…

Farm raised fish are good to eat, good for the environment and good for your health. If we eliminated farm raised fish from the menus, kitchen and homes around the world, the harm that would be done is almost incalculable. There is much misinformation, pop science and web sourced rumors to the contrary, but the real facts are quite clear. In the first place, fish is very healthy food for people. It is a nutritious, plentiful and relatively inexpensive food available across the globe. There are…

disease. There are many different types of heart diseases, and each type of heart problem requires different treatment but can have similar symptoms. If one has a shortness of breath, palpitations, faster heartbeat, nausea, he or she can be suffering a coronary artery disease. If one has discomfort or pressure in the chest, extreme weakness, or discomfort radiating to different parts of the body, he or she can possibly have a heart attack. With these symptoms occurring in one’s body, one’s body…

There are numerous treatments available for those diagnosed with atherosclerosis and coronary artery disease. Most widely known is the daily aspirin; it is recommended that all patients with documented CAD be treated with a daily aspirin (Boudi, 2015). Treatment of angina and prevention of acute cardiac symptoms includes various medications such as: nitrates, beta-blockers, statins, calcium channel blockers, and ranolazine, which inhibits the sodium current of the cardiac action potential…
