[Myocardial dysfunction in septic shock--a case report].

INTRODUCTION

Sepsis is characterized by generalized inflammatory response induced by infection. The incidence of myocardial dysfunction in sepsis is unknown as well as its impact on survival, independently other organ system dysfunction.

CASE REPORT

A female patient, age 36, with clinical signs of septic shock was admitted to the Intensive Care Unit. After initial therapy of septic shock, patient was still haemodynamically unstable. Transthoracic echocardiography showed left ventricular dysfunction (EF = 20%), with mitral regurgitation 2-3+, tricuspid regurgitation 3+, and estimated systolic right ventricular pressure of 53 mm Hg. Inotropic drug, dobutamine, was initiated, which led to significant improvement of hemodynamic parameters. Eight days after the initiation of therapy the clinical improvement was observed and the control transthoracic echocardiography was performed. It showed the improvement in left ventricular size and function, with EF of 57%, and reduced mitral regurgitation to 2+, and tricuspid regurgitation to 1+.

DISCUSSION

A hyperdynamic state is typically present in sepsis. Myocardial dysfunction in sepsis is characterized by decreased ejection fraction, ventricular dilatation and impaired contractile response to volume loading. Cardiac output can be measured using pulmonary artery catheter, transthoracic and transoesophageal echocardiography, or by pulse contour analysis. In this patient, myocardial dysfunction was detected by echocardiography, which helped in clinical decision making to administer inotropic agent. The recovery of myocardial function was also confirmed by echocardiography.

CONCLUSION

Echocardiography can be used in septic patient for diagnosis of myocardial dysfunction, decision making, follow-up of the response to inotropic therapy, and detection of the complete recovery of cardiac function.
