Cholesterol isn't good for your heart, but people about to have a heart attack may not show problems in their blood work beforehand.A national study from UCLA found that 75 percent of heart attack patients had LDL cholesterol levels that would not have been considered a high risk for a heart attack. LDL cholesterol -- low-density lipids -- is sometimes called bad cholesterol.The study also found that half of the patients had levels that were considered optimal -- a reading less than 100.Dr. Gregg Fonarow, who conducted the study, said it could mean that current guidelines are not low enough.His team also found that more than half of patients hospitalized for a heart attack had poor levels of HDL, also called good cholesterol, according to national guidelines.The database used in the study included more than 136,000 people who had heart attacks from 2000 to 2006 and were treated at hospitals.The study was published in the January issue of the American Heart Journal.
