BackgroundThe 2013 American College of Cardiology/American Heart Association cholesterol guidelines recommend high-intensity statins for patients after myocardial infarction (MI) rather than treating to a low-density lipoprotein cholesterol goal, as the previous ATP III (Adult Treatment Panelthird report) guidelines had advised. Methods and ResultsTo evaluate the frequency of postdischarge lipid testing and high-intensity statin use among MI patients discharged on a statin during the ATP III guidelines era, we linked ACTION (Acute Coronary Treatment and Intervention Outcomes Network) Registry data to Medicare claims for 11046 MI patients aged 65years who were discharged alive on a statin from 347 hospitals (2007-2009). Multivariable regression was used to evaluate the association between lipid testing and 1-year high-intensity statin use. Only 21% of MI patients were discharged on a high-intensity statin. By 90days after MI, 44% of patients discharged on a statin underwent lipid testing (43% on low- or moderate-intensity statins and 49% on high-intensity statins; P=0.001). Follow-up lipid testing rates were 47% among patients with in-hospital low-density lipoprotein cholesterol 100mg/dL and 47% among newly prescribed statin recipients. By 1year, only 14% of patients were on high-intensity statins. Only 4% of patients discharged on low- or moderate-dose statin were uptitrated to high intensity; postdischarge lipid testing was associated with a slightly higher likelihood of high-intensity statin use by 1year (5.4% versus 2.9%, adjusted odds ratio: 1.92; 95% confidence interval, 1.52-2.41). ConclusionsPrevious guidelines recommended low-density lipoprotein cholesterol goal-directed statin therapy, but lipid testing and high-intensity statin use were infrequent after MI. The American College of Cardiology/American Heart Association guidelines may promote more intensive cardiovascular risk reduction by eliminating treatment dependence on lipid testing.
