Left atrial strain predicts long-term heart failure outcomes after ST-elevation myocardial infarction.

Background: Left atrial (LA) strain reflects not only LA function but also systolic and diastolic left ventricular function. We therefore hypothesize that LA strain may be a comprehensive predictor of heart failure related endpoints after ST-elevation myocardial infarction (STEMI). We aim to assess the impact of LA reservoir strain on the long-term prognosis following ST-elevation myocardial infarction (STEMI).

Sodium Thiosulfate in Acute Myocardial Infarction: A Randomized Clinical Trial.

In this proof-of-principle trial, the hypothesis was investigated that sodium thiosulfate (STS), a potent antioxidant and hydrogen sulfide donor, reduces reperfusion injury. A total of 373 patients presenting with a first ST-segment elevation myocardial infarction received either 12.5 g STS intravenously or matching placebo at arrival at the hospital and 6 hours later.

Rationale and Design of the Groningen Intervention Study for the Preservation of Cardiac Function with Sodium Thiosulfate after St-segment Elevation Myocardial Infarction (GIPS-IV) trial.

Background: Ischemia and subsequent reperfusion cause myocardial injury in patients presenting with ST-segment elevation myocardial infarction (STEMI). Hydrogen sulfide (HS) reduces "ischemia-reperfusion injury" in various experimental animal models, but has not been evaluated in humans. This trial will examine the efficacy and safety of the HS-donor sodium thiosulfate (STS) in patients presenting with a STEMI.
