Subarachnoid hemorrhage (SAH) has been associated with electrocardiographic (ECG) changes, arrhythmias, and release of cardiac enzymes. Recently, Takotsubo cardiomyopathies, presenting typical ECG changes and left ventricular (LV) regional wall-motion abnormalities (RWMAs), have been reported and considered to be a result of high norepinephrine (NE) levels. We hypothesized that ST-T-wave changes in patients with SAH may be manifestations of Takotsubo cardiomyopathy and associated with RWMAs. ⋯ Although ECG abnormalities are frequently seen in SAH patients, the incidence of RWMAs is very low. Electrocardiographic manifestations in patients with SAH and Takotsubo cardiomyopathy are similar, but ECG abnormalities in patients with SAH are mostly not related to LV dysfunction.

The Killip classification and the Thrombolysis in Myocardial Infarction (TIMI) score have been proven to be useful tools for the early risk stratification of patients with acute myocardial infarction (MI). The Killip classification is simpler and less time consuming compared to the TIMI score. We sought to evaluate the added value of applying the TIMI score to patients prestratified with the Killip classification. ⋯ The Killip classification is a useful tool for early risk stratification of acute MI patients. Applying the TIMI score to patients classified as Killip 1 further stratified them into low-, medium- and high-risk subgroups significantly improving stratification by the Killip classification alone.

Can we do more for the STEMI patient than restore coronary blood flow?
