Coronary Artery Disease
Development of Coronary Artery Disease (CAD)
Coronary artery disease represents an obstruction or constricting (stenosis) of vessels and arteries which supplies the heart with oxygenated blood. The cause for CAD is atherosclerosis (arterial hardening), or a fatty plaque buildup on inner arterial linings. The resultant obstruction impedes blood flow across coronary arteries. The complete cut- off of blood flow leads to a heart attack (or myocardial infarction, in medical terms). CAD takes place when coronary arteries are partly obstructed or hindered, thus cutting off oxygen supply to heart muscles (i.e., myocardial ischemia). When the blockage is temporary or partial, angina (chest pain or pressure) may occur. The sudden, complete cut- off of blood flow due to the blockage leads to myocardial infarction (Milto, Costello, Davidson & Lerner, 2013).
CAD is a condition that sets it from a rather young age, a fact not many are aware of. Prior to adolescence, the walls of blood vessels start showing fat streaks. With age, this fat accumulates, injuring blood vessel walls to some extent. Proteins, calcium, inflammatory cells, cellular wastes and other substances which traverse an individual’s blood stream start sticking to vessel walls. These substances (including fat) join up with each other and form another substance – plaque. With time, the arterial interior develops plaques of varying sizes, several of which tend to be soft (internally), with a tough fibrous external "cap". The...
2). The most serious complication from coronary artery disease is the possibility of a heart attack, which can occur when blood flow to an area of the heart muscle is completely blocked, preventing oxygen-rich blood from reaching that area of heart muscle. However, the effects upon other organs of the body of coronary artery disease are still being studied by scientists. Because genetics and lifestyle are both contributing factors in heart
Especially among diabetics and others who demonstrate silent ischemia in which symptoms of the condition remain suppressed, a regular doctor checkup can help reduce chances for heart attack or death. An ECG reading will help determine if the person has developed coronary artery disease. That person can then take steps to remedy the problem. Other diagnostic measures include the exercise stress test, a coronary angiography, an echocardiogram, nuclear scan,
Heart Disease (CAD: Coronary Artery Disease) Online web site HeartPoint defines Coronary Artery Disease as Coronary artery disease generally refers to the buildup of cholesterol in the inside layers of the arteries. As shown here, this will slowly narrow the flow of blood through the vessel, and the muscle it supplies will not get enough blood. The plaque weakens the wall. As shown in the lower artery, a crack may develop
Learning Objectives: In support of the Terminal Objective, several key learning objectives will drive the content and curriculum for nurses undergoing the present training course. Primary among them, the training course is designed to create a standardized set of behaviors amongst nurses that conform with existing and evolving best practices in the perioperative care of CABG patients. This means that course content and design will be geared toward achieving procedural and
Ankylosing Spondylitis is a chronic inflammatory condition that attacks young males. It may lead to the fusion of the spine (Sarker, 2016). The fusion can result in the spin being rigid thereby making the patient develop a hunched back. Subsequently, the patient may have breathing problems because of the posture. Other inflammatory signs may show up in other parts of the body such as the eyes (Sieper & Braun, 2010). Etiology
Cardio-vascular disease (CVD) is the leading cause of death and leads the statistics for emergency room (ER) cases. This literature review combines two primary causative agents in CVD: (1) Stress in the workplace, and (2) Middle Age. This review will explore one of the key reasons why the harmful ramifications of stress and middle age can be nullified or, at least, reduced -- through physical activity and exercise. Job stress is
