The American journal of medicine, Volume 123, Issue 11, 1 1 2010, Pages 978-986 Clinical relevance of hibernating myocardium in ischemic left ventricular dysfunction. Schinkel AF, Bax JJ, Delgado V, Poldermans D, Rahimtoola SH

Patients with chronic ischemic left ventricular dysfunction may have a substantial amount of viable, hibernating myocardium, which is a state of chronic contractile dysfunction with reduced blood flow at rest. Coronary revascularization in these patients may result in improvement of left ventricular function; in the absence of viability, left ventricular function will not improve postrevascularization. Various noninvasive imaging techniques are available for detection of viable myocardium, inclu... Abstract

Heart and vessels, Volume 26, Issue 3, 30 5 2010, Pages 235-241 The 5352 A allele of the pro-inflammatory caspase-1 gene predicts late-acquired stent malapposition in STEMI patients treated with sirolimus stents. Bergheanu SC, Pons D, van der Hoeven BL, Liem SS, Siegerink B, Schalij MJ, van der Bom JG, Jukema JW

Late-acquired stent malapposition (LASM) is a common finding after sirolimus-eluting stent (SES) implantation and may be the cause for late stent thrombosis. Inflammation may play a pivotal role in LASM just as it plays in stent restenosis. We have therefore investigated seven polymorphisms involved in inflammatory processes, related in previous reports to restenosis, on the risk of LASM in SES patients. Patients with ST-elevation myocardial infarction who underwent SES implantation and had intr... Abstract
