Atheroma

Stress directly effects the body and its ability to function. An individual suffering from a high stress lifestyle is suspected to increase his or her risk not only to heart disease, but also to having a myocardial infarction (MI), more commonly known as a “heart attack”. MI describes the effects of blood blockage to part of the heart in which cardiac muscle either is damaged or dies. This particular medical condition presents an increased risk because its onset can be fatal. Physiologically,…

Chapter 4 STENT DESIGNS Stents are small meshed spring like tubular structures used in angiolplasty to treat the narrow or weak coronary arteries that carry blood. The implantation of stent prevents the arteries from blowing out for a longer duration after surgery. One of the causes for blockage of arteries is the plaque deposition in the inner parts that eventually block the blood flow and may also lead to heart attacks.…

Did you know that there is a murderer around us? The number one killer in most countries is a heart attack. It growing in recent years, and it creeps toward young people. Whereas, from several years ago we have watched a heart attack infect people in the sixties and seventies, it is now infecting people in the twenties. Also in all age groups, men are more at risk of heart attack than women, but if women reached menopause, they may be equal with men in incidence because estrogen has been the…

Heart Disease in Women and their Unique Symptoms of a Heart Attack Introduction: Heart attacks are a very serious condition of the human body that require immediate attention. Heart attacks are known in the medical community as myocardial infarctions: myo- means muscle, cardio- means heart, -al means pertaining to; infarct means death of tissue (med term book). The parts come together as: tissue death pertaining to heart muscle (med term book). Each year, around one and half million cases of…

Non-ST Segment Elevation Heart Attack A heart attack occurs when a blood vessel on the surface of the heart (coronary artery) is blocked and interrupts blood supply to the heart muscle. This causes that area of the heart muscle to permanently scar. This blockage may be caused by cholesterol buildup (atherosclerotic plaque) within a coronary artery. The plaque cracks which creates a rough surface where blood cells attach, forming a clot. Chest discomfort that happens with exertion and goes away…

SOMATOM Definition Flash Unique to the SOMATOM Definition Flash are its Dual Source technology and the revolutionary Stellar Detectors. They make it possible to scan virtually any patient, both at very low radiation and contrast dose – no matter whether the patient has an unstable heart condition, cannot hold his breath, or is obese, very tall, poly-traumatized, or a moving child. Its unmatched innovations include a 78 cm gantry bore, 307 kg capacity, 2 x 100 kW, 2 m scan range, whole-organ…

"Cholesterol Case Study" 1. Why is John’s doctor concerned about his blood work? What is the risk of having high total cholesterol? LDL? Triglycerides? John’s doctor is rightfully concerned for him. Having high total cholesterol, LDL, and triglycerides can indicate a higher likelihood of developing cardiovascular disease. From class, I’ve learned that elevated or too much cholesterol, in particular, can lead to atherosclerosis a condition that entails formerly healthy arterial walls becoming…

coronary artery is the cause of coronary artery disease. The plaques are known as atheromatous plaques (atheromas) and result in thickening of the arterial wall and narrowing of the artery. The amount of blood that is able to reach the myocardium (heart muscle) is then restricted, resulting in a decrease in the amount of oxygen and nutrients that is able to reach the heart (Mandal, 2014). An atheroma develops from damage to the endothelium of the artery. The damage in the artery allows for fats,…

Pathophysiology Myocardial infarction, or heart attack, is most commonly caused by atherosclerosis, a condition in which fibrinous plaques, called atheromas, develop within the walls of the arteries, impairing the flow of blood. High levels of low-density lipoprotein (LDL), a component of cholesterol, are a major contributor to the formation of atheromas. A myocardial infarction occurs when a plaque completely occludes a coronary artery, or when an emboli travels to the coronary artery.…

can then reduce the volume of blood that pass through them. The lack of poor blood flow can lead to myocardial ischemia, which is a lack of blood flow to the heart and it can lead to heart tissue death. Another condition associated with CAD is atheroma. Atheroma starts to develop when the endothelium part of the artery is destroyed. When the endothelium part of the artery is destroyed an accumulation of cholesterol, fats and lipoproteins start building up at the site of the injured wall. Over…
