Cardiomegaly Informative Speech

In Falcon’s report “Heart Disease” he anatomically describes the heart as “a fist sized organ located in the lower left quarter of the chest…[consisting] of four chambers: the right and left atria on top and the right and left ventricles at the bottom” (Falcon). While the heart is one of the smaller organs in the body, it has an enormous and important job to do; deliver nutrient carrying blood to the tissues in the human body. In people with heart disease, the heart is impeded and cannot efficiently deliver nutrients and oxygen to structures such as our muscles or our brain. This is one of the reasons that heart disease is so deadly; when our body structures are deprived of necessary nutrients, they begin to breakdown. The term “heart disease” encompasses a wide variety of

Apical hypertrophic cardiomyopathy is a disease that mainly affects the apex of the heart and does not cause any obstruction. [1] These abnormalities in the heart muscle can cause a wide variety of symptoms. As the heart becomes stiff it increases the pressure in the left ventricle which can push blood back into the lungs, causing shortness of breath in exercise. Chest pain can occur as there is not enough oxygen available to the cardiac muscle due to insufficient blood supply. Palpitations and lightheadedness, along with other conditions can occur as a result of HCM. In addition to these discomforting symptoms, the patient may develop an arrhythmias that often goes unnoticed. An arrhythmia takes place as the electrical conduction of the heart is disturbed by the abnormal scattering of myocytes. The two most common arrhythmias are atrial fibrillation causing palpitations, and ventricular tachycardia that can be life threatening causing sudden death. Both conditions can be controlled with medication. [4]

The heart is one of the most important organs in the body. The heart is responsible for pumping blood throughout the human body supplying the tissue with oxygen and nutrients and removing carbon dioxide and waste. If the heart does not supply blood and oxygen to the organs and tissues, they will die.

Heart Failure is a progressive heart disease when the muscle of the heart is weakened so that it cannot pump blood as it should; the blood backs up into the blood vessels around the lungs and the other parts of the body (NHS Choice, 2015). In heart failure, the heart is not able to maintain a normal range cardiac output to meet the metabolic needs of the body (Kemp and Conte, 2012). Heart failure is a major worldwide public health problem, it is the end stage of heart disease and it could lead to high mortality. At present, heart failure is usually associated with old age, given the dramatic increase in the population of older people (ACCF/AHA, 2013). In the USA, there are about 5.7 million adults who have heart failure, about half of the people die within 5 years of diagnosis, and it costs the nation an estimated $30.7 billion each year (ACCF/AHA, 2013).

Hey, have you heard of an axolotl? They are amphibians that come in various colors. That’s what the article about plus their cool features and why I would become the animal Axolotl if I could become any animal.

B. With the use of Steroids for men, the effects can be quite scary. WebMD.com states “Men who take anabolic steroids may: Develop breasts, Get painful erections, Have their testicles shrink, and have decreased sperm count.

“Obesity is a disease that affects more than one-third of the U.S adult population (approximately 78.6 million Americans). The number of Americans with obesity had steadily increase since 1960, a trend that has slowed down in recent years but show no sign of reversing”.

Cardiac muscle-The cardiac muscle is the heart, it is responsible for pumping blood around the body. It is made up of cardiac muscle and is the only location in the body where such muscle is found, Unlike other muscles, cardiac muscle is almost completely reliant on oxygen to function, Cardiac muscle is an involuntary muscle that is present in the heart and helps to synchronize the beating of the organ.the cardaic muscle is very strong and it resiatnt fatigue, The cardiac muscle is found in the walls of the heart and is responsible for keeping the heart pumping.

The heart is an organ that pumps oxygenated blood to the body and deoxygenated blood to the lungs. Heart failure is when the heart can’t pump blood very well. If the heart fails to work properly, a major system called the circulatory system won’t work properly and therefore the whole human body will fail to work properly because the cells won’t be able get oxygenated blood and use the oxygen to undergo cellular respiration and make energy.

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

In cardiomyopathy the heart muscle becomes enlarged, thick or rigid, and in rare cases the muscle tissue can be replaced with scar tissue. As this disease worsens, the heart becomes weaker and unable to pump blood normally through the body and maintain a normal electrical rhythm. This can lead to heart failure or irregular heartbeats. The weakening of the heart also can lead to other problems such as heart valve problems. Cardiomyopathy can be acquired or inherited. It can affect people of all ages. There are various types of cardiomyopathy includes, hypertrophic, dilated, restrictive cardiomyopathy, Arrhythmogenic right ventricular dysplasia and unclassified cardiomyopathy. Some people with cardiomyopathy will never have any signs and symptoms. But in some people the signs and symptoms will develop in the early stages of the disease. As cardiomyopathy worsens and the heart weakens, signs and symptoms of heart failure usually occur. The signs and symptoms of cardiomyopathy includes, shortness of breath or trouble breathing, especially with physical exertion, fatigue, swelling in the ankles, feet, legs, abdomen, and veins in the neck. Other signs and symptoms may include dizziness, light-headedness, fainting during physical activity, irregular heartbeats, chest pain, especially after physical exertion or heavy meals, and heart murmurs. The treatment of cardiomyopathy include lifestyle changes, medicines, surgery, implanted devices to correct arrhythmias (National Heart, Lung, and Blood Institute,

If you’ve done your research, you know lap band surgery is expensive. On the other hand, not all insurance plans offer the coverage you need to reduce some of the costs. For those in serious need of weight loss surgery, needing medical help but not being able to afford it can be dangerous and frustrating.

Heart failure is a condition in which the heart muscle becomes too weak to maintain an adequate cardiac output to meet the body’s

could you imagine a world where you aren’t able to hear a sound? Well, for hundreds of thousands of people this is unfortunately their reality. However, with advances in technology people are now able to hear for the first time and let me tell you, that’s certainly music to my ears. A new piece of medical technology known as the cochlear implant is a life changer that helps the deaf to live a normal life.

The hearts role is to pump oxygenated blood to every cell in the body by having a continuous beat. Throughout time the heart has created mystery, however current technology has solved most of the mystery, there still remains an enchantment and eagerness to learn more.
