Research Paper On Heart Disease

Heart disease According to hrsonline.org, “In the United States alone there are 5 million people with a heart disease. Every year 350,000 people die from a coronary disease.” A coronary disease (heart disease) is several conditions in which prevent the heart from completing its functions and affects the structures of the heart (heart.org 3). A few of these diseases are cardiomyopathy, coronary heart disease, hypertension, and tachycardia. These conditions are only a few of a hundred possibilities that can go wrong with the heart. The differences in the diseases is how they affect the heart and what part of the heart is targeted to malfunction. Other differences may include how they change
Heart disease can be treated and reversed, bringing a person back to normal health. Yet, all of these diseases can result in death as well.
Normal Heart: Just as hrsonline.org stated, “A normal healthy heart is a fist sized muscle that pumps blood 24 hours a day, 365 days a year, without rest. The heart is a part of the circulatory system which contains the heart, lungs and the blood vessels (Cohen 3).
The cardiovascular system contributes to the homeostasis of other body systems by the transporting and distributing blood throughout the body to deliver materials (such as oxygen, nutrients, and hormones) and carry away waste. The structures involved in these important task are blood vessels, which form a closed system of tubes that carries blood away from the heart, transports it to the tissues of the body, and then treturns to the heart. The five main types of blood vessels are arteries, arterioles, capillaries, venules, and
This disease is when the blood pressure is 140/90 or higher. Hypertension is also a circulatory disease. Hypertension causes the heart to become larger and thicker, weakening the heart. This makes the heart unable to pump the blood and oxygen to the body (Medical News Today.com 4). According to Medical News Today, “having high blood pressure for a short amount of time is a normal to many situations. However a systolic reading of 180 mm Hg or higher or a diastolic reading of 110 mm Hg or higher could be a sign of hypertensive crisis”. When the blood pressure is high it causes the blood to push against the walls of blood vessels. This could cause significant damage. With age blood pressure steadily increases. And the arteries become stiff and narrow. Throughout the day, blood pressure will vary, lowering while you sleep and rises when you awake. It also rises due to excitement, anxiety, and physical activity. There are two types of hypertension, primary hypertension and secondary hypertension. Primary does not have a specific cause. Yet multiple factors are the result of this. Secondary hypertension does have specific causes. They are secondary to another problem. Hypertension has affected nearly 75 million people in the U.S. (Medial News Today.com 7). Tachycardia: Lastly, tachycardia, this is when the heart rate is greater than a 100 beats per minute. Tachycardia can occur in either the atriums or ventricles of the heart. The three types of tachycardia
