Cardiogenic Shok Some Notes Develops in 10% to 20% of patients hospitalized AMI Mortality of such patients

approximately 80% or higher Very few patients develop shock immediately after AMI About half of the patients develop shock within 24h Pathology

Clinical signs ECG shows the pattern of AMI or acute coronary insufficiency The SBP < 80 mm Hg * Pulse rate is 100 per min or faster** The urinary output is low, 30 ml or less

per hour There are clinical signs of peripheral circulatory collapse Differential diagnosis Massive pulmonary embolism Acute dissecting aneurism of the aorta

Acute cardiac tamponade Acute hemorrhage Cerebrovascular thrombosis Diabetic acidosis Acute pancreatitis Acute adrenal insufficiency

Starlings law of the heart The ability of the heart to increase its output in response to an increase in venouse return represents a positive feedback in which altered blood flow to the

heart leads to a corresponding change in blood flow leaving the heart. Emergency treatment The first priority in treating cardiogenic shock is to expand

the circulating blood volume with IV fluids , using the PWP or CVP as a basic guide Initial treatment 1. Position the patient* 2. Make certain that there is an adequate

airway** 3. Maintain adequate oxygenation*** 4. Start an IV infusion of D5W,using a regular drip bulb at a minimal flow rate 5. Insert a Swan Ganz catheter into the PA 6. Draw blood for the tests

Initial treatment 1. Insert a Foley catheter into the urinary bladder to obtain accurate measurements of urinary output* 2. Monitor the patient continuously** 3. Relieve pain*** 4. Relieve agitation****

5. Take portable X ray films of the chest Definitive treatment Correction of hypovolemia Treatment of arrhythmias Treatment of hypotension Treatment of metabolic acidosis

Treatment of electrolyte disturbances Mechanical circulatory assist Correction of hypovolemia PWP less than 15 mm Hg

PWP remain stable .16 mm Hg Initial PWP is between 15 18 mm Hg PWP is 20 mmHg or higher* Rise in PWP to 16 mm Hg or higher PWP is low approximately 5 mm Hg Pulmonary edema**
