Review Meta AnalysisEffects of intracoronary autologous bone marrow cells on left ventricular function in acute myocardial infarction: a systematic review and meta-analysis for randomized controlled trials.
Experimental and clinical studies have suggested that intracoronary infusion of bone marrow-derived stem/progenitor cells (BMC) may improve left ventricular function after acute myocardial infarction (AMI). We conducted a systematic review and meta-analysis to investigate the efficacy and safety of BMC therapy on global left ventricular function in AMI. ⋯ On the basis of present evidence, intracoronary BMC infusion in patients with AMI seems to be safe and associated with slight improvement of the left ventricular ejection fraction at 3-6 months' follow-up.

Comparative StudyIncreased peripheral circulating inflammatory cells and plasma inflammatory markers in patients with variant angina.
Emerging data suggest that inflammation may play an important role in the pathogenesis of coronary artery disease. However, the relation of inflammatory status to coronary vasospasm has been less investigated in patients with variant angina (VA). ⋯ Taken together, these findings suggested that more chronic, severe inflammation might be involved in the pathogenesis of VA, manifested by increased counts of circulating inflammatory cells and elevated plasma levels of CRP and IL-6.

Predictive value of noninvasively determined endothelial dysfunction for long-term cardiovascular events and restenosis in patients undergoing coronary stent implantation: a prospective study.
Endothelial dysfunction plays a key role in atherosclerosis and predicts future cardiovascular events in individuals with or without coronary artery disease and improves with risk reduction therapy. We sought to determine the predictive value of endothelial dysfunction for long-term cardiovascular events and in-stent restenosis in patients undergoing percutaneous coronary intervention (PCI). ⋯ Impaired brachial artery FMD is associated with long-term cardiovascular events and in-stent restenosis in patients undergoing PCI. Noninvasive assessment of endothelial function may serve as a surrogate marker for the estimation of future cardiovascular event risk and long-term follow-up in these patients.
