Coronary artery disease

Joanne’s body responds to hypovolemic shock by triggering the cardiovascular, renal, hematologic and neuroendocrine system for support. The Hematologic system responds to major blood loss by activating coagulation cascades and constricting the vessels that are currently bleeding by release of thromboxane A2 and platelets. What this does is form a colt on the bleeding site. Collagen is exposed by damaged vessels which cause fibrin production and stabilize the clots that have been formed. Usually…

Blood is pumped to the brain from the heart through four main arteries. These arteries deliver nutrients such as oxygen and glucose needed for neural tissue to survive and thrive. A stroke reduces or halts the blood being supplied to distal brain tissue thus depriving it of its basic needs for survival and as a result neural…

1. Blood pressure is the force of blood pushing through the body into the arteries. Hypertension is high blood pressure. This is because there is an overwhelming pressure of blood that flows through the artery wall. 2. There are various things that can affect the resting blood pressure due to the fact blood pressure is constantly changing minute by minute in response to mood, activity, body position, etc. Factors that can change or affect your resting blood pressure reading include caffeine…

Blood pressure is measure of blood flow forcing against the walls of the arteries. Hypertension is a medical condition when the systolic blood pressure measures more than 140mmHg and diastolic measures more than 90mmHg. The World Health Organisation considers hypertension as a serious epidemic. According to the last estimate by WHO, 40% of the adults aged 25 and above had been diagnosed with hypertension. In 1980, 600 million people around the world had Hypertension, by 2008, there were 1…

An invasive approach including percutaneous coronary intervention (PCI) improves clinical outcomes in clients with ST-segment elevation myocardial infarction (STEMI) and in clients with non-ST-segment elevation acute coronary syndromes (NSTEACS) (Mehta et al., 2012). Periprocedural major bleeding is a strong autonomous predictor of early and late major adverse cardiovascular events and mortality (Bertrand, Larose, & Rodes-Labau, 2009; Verneugt, Steinhubl, & Hamon, 2011; as cited in Bernat et al.…

5. What are the potential contraindications that can prevent someone from having a cardiac catheterization? What is the contraindication that must be considered in Robert Wilson’s case? Why is this of concern? There are potential contraindications to getting a cardiac catheterization, though the only contraindication is the inability to provide an informed consent. There have been unstable patients how have tolerated this procedure but with high risk patients, the nurse has be cautious of…

Introduction: The heart rate of an animal can be used as an indicator to identify when a stimulus evokes a reaction from the animal. Specifically in the case of humans’, there tends to be the cognitive ability to physically withhold a reaction from a stimulus and mask the involuntary reaction. However, the heart rate reacts immediately after a stimulus, and is not reigned in or controlled cognitively, so could the heart potentially be a true indicator of an individuals reaction to a stimulus?…

Abstract The purpose of this exercise laboratory experiment was to, analyse and observe the role that exercise plays in affecting the blood pressure and heart rate of a patient, with and without the consumption of caffeine. In this experiment, a cycle ergometer (Monark 824E, Monark Exercise, Sweden) was used in an incremental style type exercise that measured the fourteen healthy participants blood pressure and heart rate at various interval stages. The blood pressure and heart rate were…

Saturated fats are the bad type of fat. Saturated fat raises the levels of blood cholesterol and can clots arteries. It is found in animal products such as beef, pork, chicken, milk, ice crème, and cheese. Trans fats are also artery clogging fats, and are just as bad as saturated fats. They are created through hydrogenation, a process that turns liquid fat into solids like margarine or shortening. Unsaturated fats are…
