Late percutaneous coronary interventions do little goodIf you’re going to open a blocked coronary, do it quick or don’t bother, at least if you’re trying to have a long-lasting effect. Percutaneous coronary interventions (PCIs) using stents and balloons won’t make any difference in preventing second heart attacks, death, or development of heart failure if performed three or more days after a heart attack, according to research presented this week at the American Heart Association meeting.Toshiba launches faCTor64 studyGerman firm unveils dose shieldACR schedules ‘face’ time
