Metoprolol Metoprolol is a beta-Adrenergic blocking agent. Beta receptors are part of the sympathetic nervous system and are found on cells of the heart‚ smooth muscles‚ in airways‚ arteries and kidneys. Associated with stress response‚ they are stimulated by epinephrine. Beta blockers interfere with the binding of epinephrine at the receptors. Metoprolol works by inhibiting the response to adrenergic stimuli by blocking beta one adrenergic receptors within the myocardium. (Hoffman‚ Jones

Describe the preoperative and postoperative care of a client having PTCA/cardiac cath. What complications can occur post cardiac cath? The goal of PCI (percutaneous Transluminal intervention) is to open the blockage in the coronary artery. By opening the area that is blocked‚ it will help to reperfuse the myocardium. The faster this is done will help

Overview of Pulmonary Embolism An embolism is a foreign mass that travels through the intravascular space carried by the systemic circulation. The mass may be solid‚ liquid or gaseous. The circulation carries the embolus through vessels to parts of the body where it can cause obstruction or occlusion. The Pulmonary Embolism (PE) occurs when the embolism causes an obstruction or occlusion of the pulmonary artery or one of its branches‚ which in turn reverts pressure on the right ventricle. A solid

the catheters became small enough to be placed non-surgically at patient’s bedside (IABPumpers‚ 2006). Now‚ with more than 70‚000 balloon catheters inserted each year in the U.S‚ IABP therapy is known to be the mostas a common treatment for cardiogenic shock (Vales‚ Kanei‚ Ephrem‚ & Misra‚ 2011). Purpose of Technology The most important purpose of the IABP therapy is to increase cardiac output (Vales‚ Kanei‚ Ephrem‚ & Misra‚ 2011). As stated previously‚ tThe IABP is timed to inflate and deflate

Treating Heart Failure When a patient’s heart is no longer able to pump a sufficient amount of blood around the body‚ they are referred to as having heart failure. The heart muscle has been damaged or overworked and is therefore unable to pump as effectively as before. Coronary heart disease is the most common cause of heart failure‚ cardiomyopathy and hypertension are also implicated (Peterson et al‚ 2002). Heart failure can present acutely or chronically. Chronic heart failure tends to worsen
