Cardiovascular Diseases
The heart is an essential organ in the cardiovascular system responsible for pumping oxygen and nutrition filled blood to all parts of the human body. It is composed of four chambers; two upper chambers called the right and left atrium, and two lower chambers called the right and left ventricle. A structure called the septum is what divides the heart into right and left halves. Four heart valves keep the flow of blood in one direction. At rest, the heart usually beats 60 to 80 times per minute and is the size of the person’s fist (Dowshen, 2013). When a heart becomes abnormally larger, it is known as cardiomegaly. Cardiomegaly is not considered a disease, but rather a symptom caused by numerous …show more content…
Having a high blood pressure is a common condition that requires the heart to pump harder than normal, and as a result, causes the heart to enlarge (Stöppler, n.d.). Congenital heart defects can cause the heart to pump harder by being able to change the flow of blood through the heart (Mayo Clinic Staff, 2011). Arrhythmia and prolonged anemia are also conditions that can cause the heart to pump harder and lead to cardiomegaly (Stöppler, n.d.). People with arrhythmia have an abnormal heart rate and lack a heart that pumps blood effectively. This forces the heart to pump harder in order for blood to reach all parts of the body. Anemia is a condition where the body does not have enough red blood cells. Heart valves damaged by rheumatic fever, infections, and etc. and thyroid disorders are other causes for cardiomegaly. Sometimes, the cause for cardiomegaly are simply unknown or idiopathic (Mayo Clinic Staff, …show more content…
Conditions that can cause an enlarged heart include high blood pressure, heart valve disorders, and arrhythmia. Often, people with cardiomegaly do not experience signs or symptoms. Those who do can suffer from chest pains and dizziness. Treatments for cardiomegaly are focused on curing the condition that caused it. Such treatments include diuretics and beta blockers for lowering blood pressure. Those who received cardiomegaly from a heart valve disorder can have surgery to either repair or replace the injured valve. If nothing works, a heart transplant is an

    The heart is what some determine to be the most important organ in our bodies and one of the biggest contributors. It is one of the major organs that if we did not have, it would not be possible for us to live. The heart is about the size of a fist and is broken down into four chambers, the aorta, superior vena cava, pulmonary artery, and the coronary artery. The four chambers include the right and left atrium and the right and left ventricle. The heart is responsible for supplying oxygen and blood to the entire body. Blood passes through these four chambers and then exits and pumps into the rest of the body. The heart also has three layers of walls…

    The heart is the organ that supplies blood and oxygen to all parts of the body and is connected with the circulatory system. It pumps blood throughout the blood vessel by contractions. The male’s heart weight between 9 and 11 ounces and the female’s heart weighs about 11 to 12 ounces (Bradley, 2013). A person’s blood pressure has major effects on their heart where high blood pressure is a major risk factor for a heart attack. When the heart isn’t receiving enough oxygen a person will develop chest pains, known as angina where the blood flow is blocked, and results in a heart attack (Casey, 2013).…

    The function of the heart is to pump blood throughout the body. The heart pumps blood containing oxygen from the lungs to body. It passes blood without oxygen back to the lungs for more oxygen. The heart has four chambers; the two upper chambers are called atriums, and the two lower chambers are called ventricles. The left atrium is located above the left ventricle, and they are separate by a valve called the mitral valve. The…

    Right Sided Heart Failure Essay

    Right-sided heart failure is a consequence of left ventricular failure. When the fluid pressure increases in the left ventricle, but is too weak to pump the fluid out into the aorta, the fluid regurgitates into the left atrium and subsequently backs up into the lungs. In the same manner, the right ventricle pump deoxygenated blood to the pulmonic vein but is met with great resistance due to congested lungs, thereby pushing the fluid back into the right atrium, and into the vena cava. This backing up of blood causes swelling of the abdomen, legs and ankle.…

    The heart lies in the thoratic cavity, organs associated with the heart are inferiorly, the hearts apex rested on the tendon of the diaphragm, superiorly, the great blood vessels, posteriorly the oesophagus, trachea and the left and right bronchus, laterally, the lungs and anteriorly the sternum and ribs. (Waugh& Grant 2014). The heart provides a constant blood circulation action and the blood vessels provide a network for the blood flow. The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body, ( www.le.ac.uk) the right side of the heart pumps blood to the lungs (pulmonary circulation) and the left side receives oxygenated blood and supplies it to the rest of the body (systemic circulation). There are three types of blood vessel, arteries, capilleries and veins. Blood is pumped from the heart through the arteries at high pressure which could damage the tissue so it needs to go through the capillaires which are smaller low pressure blood vessels that are responsilbe for providing oxygen to the tissues, they also absord excess carbon dioxide and then deliver the blood into the veins which then supply the blood back to the heart. The heart generates its own electrical impulses, it does not rely on any other external mechanisn to make it beat. A normal heart rate is 60-80 times per minute, factors which can decrease or…

    With right-sided congestive heart failure, the heart is damaged and unable to properly pump the blood flowing from the body back to the heart. This causes a backup of blood and an increase of pressure in the veins that carry the blood to the heart. This results in swelling, also called edema, of the lower extremities or other areas of the body.…

    Congestive Heart Failure Essay

    Congestive Heart Failure can be brought on by many conditions. These conditions include Coronary Artery Disease, Heart Attack, and lastly Cardiomyopathy. Coronary artery disease can develop in humans after years over time after years of fatty deposits in the vascular system (Arteriosclerosis). After a heart attack the heart muscles are weakened and cannot perform the way they could prior to the attack. Therefore, as the muscles lose their pumping ability the heart cannot work to its full potential causing for the heart to fail. Lastly in cardiomyopathy the heart fails because of other risk factors such as drugs, chemotherapy, and infections. Infections such as pericarditis where the pericardial sac becomes infected causes the heart to not pump effectively which leads to Congestive Heart Failure. The risks factors include hypertension, male gender, diabetes, a diet high in fats and a previous heart attack.…

    Dilated cardiomyopathy is a condition in which the heart's left ventricle becomes enlarged and weak, reducing the heart's ability to pump blood. Over time, the disorder can damage multiple organs and lead to congestive heart failure. According to the Cleveland Clinic, about one-third of patients with dilated cardiomyopathy have an inherited form called familial dilated cardiomyopathy. Familial dilated…

    Congestive Heart Failure

    There are many ways to treat this condition. ACE inhibitors may be prescribed. These drugs are vasodilators, and help to widen blood vessels to reduce the workload on the heart, decrease blood pressure and increase blood flow (Mayo Clinic Staff, 2013). Many people with this disease are also prescribed diuretics, to increase fluid loss from the body and reduce fluid buildup and swelling. However, patients often need mineral supplements in addition to taking these drugs. When drugs are not sufficient enough, surgery may also be required. A coronary bypass is a sort of transplant, where veins from an arm or leg are used to bypass a blocked coronary artery, allowing blood to flow freely through the heart. Beta blockers are drugs that block Beta 1 and 2 receptors on the heart, which constrict blood vessels. By doing this and keeping blood vessels dilated, these drugs reduce blood pressure and heart rate. However, Carvedilol is the only agent labeled by the FDA for use in patients with heart failure (Chavey, 2000).…

Another disease, like diabetes, may also cause heart failure. Heart failure sometimes is hereditary that occur as a result of defect in heart at birth. Lung disease is one of causes because when lungs does not work well, heart should work harder to deliver oxygen to body organs. There are many symptoms that show if the person has or will have heart failure or not. For example, high heart rate, shortness of breathing, and chronic coughing. Also impairment in the ability to think and accumulation of fluid (edema) could be signs of heart…

    Congestive Heart Failure

    Congestive heart failure occurs as a result of a number of diseases which cause weakening or stiffness of the heart muscle which prevents the heart from keeping up with the body’s normal demand for oxygen rich blood. When the heart cannot keep up with the demand for oxygen and nutrients to meet the needs of the body, over time, the muscle fibers of the heart stretch to hold more blood, hormones are released to increase the pumping power and causing the walls of the heart to thicken from overuse. (Murphy, 2013) Although the symptoms of heart failure vary, they can include fatigue, weakness, rapid irregular heartbeat, edema, difficulty breathing, cough, memory loss, disorientation, sudden weight gain from fluid retention and decrease in exercise. Congestive heart failure left untreated eventually effects every organ in the body.…
