Of patients with cardiogenic shock (n=2,093) identified at contemporary North American CICUs, 1,405 (67%) had heart failure related cardiogenic shock (HF-CS), defined as cardiogenic shock in the absence of acute myocardial infarction. Approximately 1 in 4 patients with HF-CS did not have a prior history of HF (de novo HF-CS). A greater proportion of patients with de novo HF-CS had preceding cardiac arrest as compared to those with acute-on-chronic HF-CS.
* Excludes post-cardiotomy shock and shock primarily due to severe valvular disease, arrhythmia, or tamponade
