Multicenter Study Comparative StudyAssociation of vitamin D levels with incident depression among a general cardiovascular population.
Depression is associated with cardiovascular (CV) disease, and it has been hypothesized that vitamin (vit)D deficiency may be associated with depression and a contributing factor to excess CV events. Therefore, we evaluated whether there is an association between vitD and incident depression among a CV population. ⋯ Among a CV population > or =50 years with no history of depression, vitD levels were shown to be associated with incident depression after vitD draw. This study strengthens the hypothesis of the association between vitD and depression.

Randomized Controlled Trial Comparative StudyEarly dynamic risk stratification with baseline troponin levels and 90-minute ST-segment resolution to predict 30-day cardiovascular mortality in ST-segment elevation myocardial infarction: analysis from CLopidogrel as Adjunctive ReperfusIon TherapY (CLARITY)-Thrombolysis in Myocardial Infarction (TIMI) 28.
Troponin is the preferred biomarker for risk stratification in non-ST elevation ACS. The incremental prognostic use of the initial magnitude of troponin elevation and its value in conjunction with ST-segment resolution (STRes) in ST elevation myocardial infarction (STEMI) is less well defined. ⋯ Baseline TnT and 90-minute STRes are independent predictors of 30-day CV death in patients with STEMI. Use of these 2 simple, readily available tools can aid clinicians in early risk stratification.

Comparative StudyEarly ST-segment recovery after primary percutaneous coronary intervention accurately predicts long-term prognosis after acute myocardial infarction.
Several ancillary studies reported on the prognostic value of ST-segment recovery (STR) with measurement at 30 to 240 minutes after primary percutaneous coronary intervention (PCI). We determined the long-term prognostic value of early STR, assessed at the end of primary PCI, in unselected patients after ST-segment elevation myocardial infarction (STEMI). ⋯ Early STR assessment has strong, long-term prognostic properties in all-comer STEMI patients. Moreover, the prognostic power of early STR is not restricted to the early recovery phase after STEMI, but identifies high-risk subgroups among 1-year survivors.
