CLINICAL UPDATE - Industry slams b vitamins trial

A clinical trial that concluded B vitamins do not reduce the risk of cardiovascular events or death among patients with coronary heart disease has been criticized by industry for being poorly designed

CLINICAL UPDATE - aspirin non-responsiveness predicts thrombosis

Study showed that patient non-responsiveness to both aspirin and clopidogrel independently predicted the likelihood of whether a stent would eventually become re-blocked

cLINICAL UPDATE - zinc deficiency promotes inflammation

Scientists demonstrate how zinc-deficient cells increased secretion of several inflammatory compounds due to the disruption in the cell membrane barrier, which did not happen in cells replete with zinc

cLINICAL UPDATE - study links lp-pla2 to oxidative stress

Markers of oxidative stress were elevated in patients that also had higher Lp-PLA2, supporting the proatherogenic role of Lp-PLA2 in coronary artery disease
