Coronary circulation

Ms. Sunshine is a fifty four year old African American woman that has a history of coronary artery disease. The ethnicity and culture of a patient has a vital role in any disease, especially coronary artery disease. A person’s socioeconomic status is associated with the health status of the person (National Heart, Lung, and Blood Institute (NHLBI), 2016). A low economic status is associated with a poor health status. According to NHLBI (2016), African Americans have the highest rates of heart…

tissues. (1) 2 Pericardium – the membrane that surrounds and protects the heart. It consists of outer fibrous layer and inner pericardium. 3 Right atrium – receives blood from three veins such as the superior vena cava, inferior vena cava, and coronary sinus. 4 Right ventricles – form most of the anterior surface of the heart. 5. Left atrium – form most of the base of the heart and it receives blood from the lungs through four pulmonary veins. Blood passes from the left atrium into left…

Two sides of the heart pump blood through two different circulations. Pulmonary circulation involves movement of blood from the right ventricles to the lungs. Systemic circulation involves movement from the left ventricle, throughout the body. When the heart beats the atria contract first in atrial systole. When the ventricles fill with blood, they too contract together…

Muscular system: Major functions The muscular system function is that it allows movement of body parts, and works with skeletal system to help us move. Major muscles types : There are many muscles in the muscular system. Some are skeletal, smooth, and cardiac muscle. The skeletal muscle, smooth muscle, and cardiac muscle can stretch and contract, but they complete different functions. The skeletal muscle is attached to your skeleton by strong, springy tendons or is directly connected to rough…

Several years ago, author and motivational speaker, Allen Klein visited a hospice in San Francisco. He came across an elderly woman diagnosed with a terminal disease that expressed her desire that once she dies, she wants her husbands room repainted, with her ashes mixed in with the paint. Klein was confused at this odd request and asked why she would want such a thing. The old woman replied, “So I can look down at my husband and see if there’s any hanky-panky going on” (Horovitz, 2017, para.…

mechanical assist device that that will benefit patients with a life-threating illness such as cardiogenic shock, cardiac defects, and unstable angina (Darovic, 2002). The IABP will reduce the resistance to the left ventricular ejection and improve coronary perfusion as well as systemic blood flow (Darovic, 2002). During diastole, the balloon inflates to increase diastolic pressure higher than systole pressure while displacing blood volume equivalent to its inflation volume (Darovic, 2002). IABP…

oxygen results from atherosclerotic plaques in coronary arteries. Hence, administering glyceryl trinitrate (GTN) to john has allowed potent vasodilation of coronary arteries to increase the blood flow. Their principle benefit follows from a reduction in venous return which reduces the left ventricular work. Aspirin as an antiplatelet drug decrease platelet aggregation and may inhibit further thrombus formation in arterial circulation, including the coronary vessels. Administration of aspirin…

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…

October 4th, I spent the day at The Miriam Hospital cardiac catheterization laboratory. Cardiac catheterization is an invasive diagnostic procedure that uses imaging equipment to identify if a patient has disease of the heart muscles, valves or coronary arteries (Smeltzer, 2011). Upon arriving at 0720 the nurse manager greeted me and the other student, and gave us a quick tour of the control area and examination room. We were informed about the safety precautions used to protect ourselves from…

poor blood circulation. Update on congestive heart failure. The heart is a muscle that beats to pump oxygen-rich blood and nutrients to the body via the circulatory system. Inside the heart are four chambers which collect blood and then distribute it to the lungs and the body. Several conditions can hamper the ability of the heart to effectively pump blood. Abnormalities or muscle disease or heart valves can cause failure of the heart to maintain an adequate blood circulation. Coronary artery…
