Introduction: High-sensitivity cardiac troponin assays have provided a significant contribution for the early diagnosis of cardiovascular events due to their ability to detect lower concentrations of troponin levels more rapidly. There is significant evidence about the association between the absolute value of elevated cardiac troponin levels with the prognosis of patients with chest pain (3). However, it is well-known that elevated cardiac troponin levels may occur in situations other than…

Ms. Barth presents in a hyper-adrenergic state that causes acute pulmonary hypertension. Consequently, this causes pulmonary edema due to an increased hyperstatic pressure. Globally, she has systemic hypertension a result of vascular spasms and increased heart rate. Symptomatically she feels hot, sweaty, and anxious due to vasoconstriction (increasing heat retention) stimulation of sweat glands, and increased norepinephrine. The cardiovascular system is dynamic and always changing to regulate…

percutaneously is the“most exciting advancement in the treatment of valve disease” (Kenny & Hijazi, 2013, p795).The pulmonary valve and aortic valve are two valves that can be treated or replaced in thecatheterization lab through a percutaneous TVR. Patients will present with pulmonary stenosisor aortic stenosis. Pulmonary stenosis is defined as “the narrowing of the opening between thepulmonary artery and the right ventricle”…

Question 1. a) “What serosal cavities have been penetrated by the 1st arrow?” The pleural cavity and pericardial cavity have been penetrated by the 1st arrow as they tend to appear in the thoracic cavity on the left side of the chest. b) “Explain the location, the microscopic characteristics of the serous membrane, and the purpose of the serous membrane.” The serous membrane, the peritoneum is located within cavities of the abdomen and the pelvis. Pleura are found in the thoracic cavity…

caused when the heart slows and the blood begins to back up into the lungs. When the heart fails, the arteries that supply the heart muscle are narrowed known as coronary artery disease. The edema or swelling, is a sign of the heart failing to pump effectively. Many signs and symptoms include tachycardia…

increases resistance on the pulmonary arteries. This confirms that Henry has pulmonary hypertension.…

The spleen can be found in the left upper quadrant of the abdomen, lying posteriorly to the stomach and underneath the diaphragm. The spleen can be found enclosed in a capsule of dense irregular connective tissue (Krause, 2008). Prone to infections and other conditions, the spleen can easily become enlarged because it is highly vascularized. Malignancies, parasites, liver diseases and other conditions passed in the blood and immune system can cause the spleen to be infected. In addition to the…

organs; maintaining homeostasis; and transport gases, waste, and hormones. The different types of blood vessels are: arteries, capillaries, and veins. The vessels that carry blood towards the heart are veins and the vessels that carry blood away from the heart are arteries. Gas exchange occurs in the capillaries. 2. Describe the layers of blood vessels. Describe the differences between arteries and veins. The layers of blood vessels are: a hollow interior (lumen), contains an outer…

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…

Arterial system of frog Blood vessels, which carry oxygenated blood away from heart to different part of the body, are called arteries. They constitute a system called arterial system. Truncus arterious gives two branches right aortic trunk and left aortic trunk. Each aortic trunk again divides into three branches- a) Carotid arch: it divides into – Lingual artery – it supplies blood to tongue and hyoid. Common carotid – it supplies blood to buccal cavity and brain. it consists swelling at the…
