THE CAUSES OF HEART ATTACK The onset of heart attack is a result of a portion of cardiac muscle having necrosis, which is caused by an obstruction of a coronary artery through artherosclerosis, a thrombus or spasm. Heart attack often occurs when the flow of oxygen-rich blood to a section of the heart muscle becomes blocked which is mostly a result of coronary heart disease (NIH, 2012). According to National Institutes (NIH), Coronary heart disease is a condition that is as a result of a waxy…

There are several causes of high blood pressure (Hypertension) some of which we do not have any direct control over, and yet we can still modify the effects of these factors by ensuring that we pay attention to the things that we do have some control, over. I will discuss both kinds on this page so that by the end you know exactly the kind of things you can easily change to reduce the risks associated with high blood pressure, and you know the things that you cannot change so easily and yet can…

utilized to check the heart 's rhythm and electrical signals. Sensors fixed to the skin are utilized to detect the electrical signals created by the heart every time it pulsates. These signals are recorded by an ECG and are diagnosed by a cardiologist or GP to check abnormalities or presence of heart disease. The ECG is commonly used by trained technicians to analyze and screen conditions influencing the heart. It can also be used to examine side effects of a possible heart issue such as chest…

Some of the deadly consequences of malnutrition are electrolyte imbalance, muscle loss, immunity and blood flow issues, and heart problems. Once the body reaches the point of malnutrition it goes into what is known as starvation mode. When a body lacks the nutrients it needs it will take from itself. When the human body has an electrolyte imbalance caused by starvation there…

Heart Murmurs and its Effect on the Body System Unusual or abnormal sounds that are heard during a heartbeat are referred to as heart murmurs. Murmurs can range from very faint to very loud and sometimes sound like a whooshing or a swishing noise. Although heart murmurs can be present at time of birth they can also be developed later in life as well. Heart murmurs are not diseases but can indicate an underlying heart problem. Normal heart beats usually make a “lub-dub” type of sound which…

For over 55 years, humans have been flying in space. With an understanding of evolution, it has always been assumed that human bodies have adapted to the gravitational force found here on Earth. The space station and the shuttle that most NASA astronauts will stay in orbits 350 km above Earth, with a gravitational pull 90% stronger than it is on the ground (NASA Space Bones). Giancoli describes objects orbiting the Earth as feeling weightless because they are, in essence, free falling towards…

Heart disease is a broad term used to describe any cardiovascular disease or condition that affects the cardiovascular system. According to the Centers for Disease Control and Prevention (CDC), 47% of all Americans have at least one of the risk factors for heart disease and many don 't know it. Understanding heart disease is crucial to its prevention, however, so it 's important for you to know the causes and symptoms of heart disease. You should strive to prevent heart disease if you can and…

Introduction According to the American Heart Association, heart disease accounts for more than 17.3 million deaths a year and this number is expected to grow to more than 23.6 million in 2030. There are several types of heart disease, one of them being acute myocardial infarction also known as heart attack. Myocardial infarction is the damaging or death of an area of the heart muscle caused by blockage in the blood supply of that area. Myocardial infarction happens when the arteries become…

For example the bones in the skull protect the brain from damage and the rib cage protects the lungs and the heart. This is due to the thickness and strength of the bones muscle and tissue that surround the organs. Without this protection the body would be at risk of serious injury to its major…

from the pulmonary artery to the aorta. Instead, it moves into a normal circulatory pattern. Normal circulation occurs when deoxygenated blood enters the right atrium and moves on through the right side of the heart to the pulmonary system where it is oxygenated and then moves back to the heart and out of the left ventricle to supply oxygen and nutrients throughout the body (Kim, 2016). A PDA occurs when the DA fails to close completely after delivery. When the DA vessel does not constrict and…
