Coronary circulation

area with episodes of dyspnea during exertional activities like stair climbing is suggestive of vascular issues that can eventually lead to thrombus formation. Peripheral vascular disease has a risk factor profile similar to that associated with coronary artery disease like diabetes, smoking, hypertension, and hyperlipidemia as suggested by Chen, Shi, Wang & Li…

of stress by regulation of blood pressure (BP). BP can be expressed as the product of cardiac output (CO) and peripheral resistance. The arterial pressure level at any given time reflects the composite activities of the heart and the peripheral circulation.(Jones, 2004). Nervous system, hormonal and Kidney factors control blood pressure. 1. Nervous System 1.1 CO – Cardiac output CO may be increased or decreased by autonomic nervous system activity that travels between reflex centers in the…

Examination of Ventricular Septal Defects and Arterial Aneurysms According to Maternal Child Nursing Care, 5th Edition, Chapter 47 – Cardiovascular Dysfunction, congenital heart defects occur in about 5 to 8 of every 1000 live births, and 2 to 3 of those affected will be symptomatic within the first year of life (Hockenberry, 2014). When looking at the different pathophysiologies of congenital heart defects, the most common form of defect is the ventricular septal defect or VSD and there are…

Heart Attack Heart attack is the consequence and progression of worsening CAD. The coronary artery become partial of completely blocked and suddenly stop the blood flow. Without oxygen part of the heart become permanently damaged and loses its ability of contractility; resulting in scarred area or necrosis. These damage are permanent or irreversible (Mozaffarian et al., 2015). Cardiomyopathy Cardiomyopathy is a diseased heart muscle. The chambers of the heart enlarge and the heart muscle…

In order to understand exactly what Left Ventricular Hypertrophy is, it is important to be able to break down the word. The prefix Hyper- means over or more, and the suffix -trophy means well-fed. Therefore, LVH is the thickening and/ or the enlargement of the left ventricle. Under normal conditions, the left ventricle of the heart is responsible for the big push that sends blood through the aorta and to the rest of the body (Sheir 2015, p.560). When the left ventricle becomes thickened, or…

The Human Heart: A General Description The heart is the main organ of the cardiovascular system in the human body. Its primary function is to pump oxygen- and nutrient-rich blood throughout the 60,000 miles of blood vessels that make up this system ("Heart, 2015"). About the size of a clenched fist, the heart is located in the middle of the chest, between the lungs and nestled behind the ribcage. It lies a little to the left of the sternum. The shape of the heart is reminiscent of an upside…

There are many factors that can put a person at risk of developing heart disease, the three most common factors being high blood pressure, high cholesterol and smoking.

Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart. • The red blood cell carrying oxygen is pushed into the aorta through the aortic valve by contraction of the left ventricle (Marieb, Mitchell, Smith, 2013, pg. 446). • From the aorta, the red blood cell travels into one of the arteries from the arterioles then will hit the capillaries (Marieb, Mitchell, Smith, 2013, pg. 446). • Within the capillary, the oxygen molecule that is taken by the red…
