The cardiovascular system and associated disorders.

The cardiovascular system, consisting of the heart as the 'pump' and the vascular network of blood vessels, is responsible for the distribution of blood around the body. Oxygen molecules attach to haemoglobin in red blood cells and are transported around the body where the oxygen aids cellular metabolism. Any blockage in the blood vessels as a result of build-up of plaques in the endothelium layer would result in an interruption in blood supply and therefore oxygen deprivation (ischaemia). This would lead to necrosis of the distal area of the affected vessel and is known as an infarct. This article aims to describe the normal anatomy and physiology of the cardiovascular system and to explain some of the common associated disorders, with a brief guide to the management of a common heart disorder, myocardial infarction. A case study is included to enhance the knowledge of management of myocardial infarction. An in-depth knowledge and understanding of the cardiovascular system and its associated disorders will enable the nurse to safely assess a patient, recognise a deteriorating patient and seek early intervention.
