If the EKG is abnormal, cardiac

If the EKG is abnormal, cardiac monitoring may be reasonable for 24 to 48 hours or until the patient is asymptomatic and hemodynamically stable. Echocardiograms should be reserved for patients presenting with hemodynamic instability and can be helpful in identifying tamponade, pericardial contusion, or apical thrombi. Additional means of testing, such as serial enzyme monitoring, have additional costs with limited clinical benefit. Coronary

artery dissection is a rare clinical condition, with variable Nutlin-3a nmr causes including trauma, iatrogenic lesions from angiography, and spontaneous dissections. Despite the etiology of the dissection, JQ1 cell line treatment is dependent upon the location of the lesion. Patients with LMCA lesions or those with a high-risk of bleeding will likely need to undergo coronary bypass. Lesions isolated to the LAD or RCA, and with isolated trauma, can be treated with percutaneous techniques. In our GSK872 patient sustained a high-risk blunt chest trauma from a motor vehicle collision. An EKG was ordered to evaluate his symptoms, and the screening test initiated a diagnostic evaluation. Based on those findings, additional diagnostic tests–the cardiac enzymes and angiogram–were justified and provided rapid diagnosis of the coronary artery dissection. Prompt recognition, evaluation and

treatment resulted in immediate surgical revascularization and discharge to home on hospital day 19. References 1.
