Example text
A massive systemic reaction occurs and an excess of inflammatory mediators are released, causing an overwhelming physiological response, ultimately leading to tissue damage and organ dysfunction, as evidenced by the presentation scenario described for Deborah. Within a very short period following the initial insult, blood vessels carrying the circulation away from the site of insult constrict, resulting in engorgement of the capillary network. The engorged capillaries produce the characteristic swelling and redness associated with inflammation.
The myocardial cells may survive if adequate circulation to this area is restored; but if ischaemia persists, progression to necrosis is inevitable. Another consequence of anaerobic metabolism and reduced adenosine triphosphate (ATP) levels is cellular membrane disruption leading to electrolyte imbalances. The plasma membrane can no longer maintain normal ionic gradients across the membranes and the sodium/potassium pump can no longer function (Edwards, 2002). The levels of intracellular sodium [Na+ ] and calcium [Ca+ ] increase, causing cellular oedema.
A rapid ECG revealed ST segment elevation in leads V1 –V4 , indicating an anterior STEMI. , 2000). , 2000). , 2006). They are components of the cardiac contractile apparatus where they act as a calcium-sensitive molecular switch to regulate muscular contraction. As they are only found in cardiac tissue, raised levels occur only where there is cardiac damage (Collinson, 2006). , 2006; Green and Tagney, 2007). It is important to recognise that the initial diagnosis of STEMI is based on clinical diagnosis and the 12-lead ECG; management is aimed at re-establishing patency of the acutely occluded vessel by primary percutaneous coronary intervention (PPCI) or thrombolytic therapy.
