Overview
Historical perspective
The term "cardiogenic shock" is thought to have first arisen in 1942 with Stead, who after studying a series of two patients, described them as having a "shock of cardiac origin". This designation would later be rephrased as "cardiogenic shock".[1] However, the clinical features of cardiogenic shock had first been described by Herrick, in 1912, who noticed in severe coronary artery disease patients a profound weakness, a rapid pulse, pulmonary rales, faint cardiac tones, cyanosis and dyspnea.[2]
In 1967, after studying a series of 250 patients with acute MI, Killip and Kimball proposed a clinical classification of hemodynamic status, which included 4 classes and that is still in widespread use:[3]
- I - no clinical signs of heart failure
- II - S3 gallop and/or basilar rales on lung auscultation and/or elevated JVP
- III - Pulmonary edema
- IV - Cardiogenic shock
Throughout the years the outcome of cardiogenic shock has been improving, with a decrease in mortality seen particularly during the 1990's. According to the studies, from 1975 to 1990, the in-hospital mortality from this condition averaged 77%. Between 1993 and 1995 this percentage declined to 61%, reaching about 59% in 1997. For this decrease, revascularization techniques along with an aggressive approach to shock have contributed greatly.[4][5]
