Also, in some jurisdictions, reimbursement of P2Y12 inhibitors after coronary stenting may be limited to 12 months, particularly reimbursement of prasugrel and ticagrelor. On the other hand, where restrictions have been lifted &#x02014; in particular for clopidogrel &#x02014; it may be important to ensure that extended therapy will result in optimal outcomes for patients after PCI and not result in more harm. Accordingly, given the current uncertainty about the benefits and harms of extended DAPT beyond one year, further elucidation of the available evidence, including the assessment of both the clinical and economic impact, is required to inform health care decision-makers, policy-makers, clinicians, and patients.</p></div><div><h2>Contents</h2><div class="bktoc_all_cntnr top align_right" style="display:none"><ul class="inline_list_right"><li><a class="bktoc_all_exp" href="#">Expand All</a></li><li style="margin-left:.8em"><a class="bktoc_all_clps" href="#">Collapse All</a></li></ul></div><ul id="toc_tllNBK542937_toc_fm-ch1" class="simple-list toc toc-toggle"><li class="half_rhythm" id="toc_itm_NBK542937_toc_fm-ch1"><a class="toc-item" href="/books/n/op0533/fm-ch1/">Expert Consultant</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_fm-ch2"><a class="toc-item" href="/books/n/op0533/fm-ch2/">Authorship</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_fm_ack"><a class="toc-item" href="/books/n/op0533/fm.ack/">Acknowledgements</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_abb"><a class="toc-item" href="/books/n/op0533/abb/">Abbreviations</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch1"><a class="toc-item" href="/books/n/op0533/ch1/">Executive Summary</a><ul id="toc_lst_NBK542937_toc_ch1" class="simple-list toc bktoc_lst_exp"><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch1_s1"><a class="toc-item" href="/books/n/op0533/ch1/#ch1.s1">Rationale and Policy Issues</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch1_s2"><a class="toc-item" href="/books/n/op0533/ch1/#ch1.s2">Clinical Review</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch1_s3"><a class="toc-item" href="/books/n/op0533/ch1/#ch1.s3">Economic Analysis</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch1_s4"><a class="toc-item" href="/books/n/op0533/ch1/#ch1.s4">Discussion</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch1_s5"><a class="toc-item" href="/books/n/op0533/ch1/#ch1.s5">Conclusion and Implications for Decision-Making</a></li></ul></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch2"><a class="toc-item" href="/books/n/op0533/ch2/">Rationale and Policy Issues</a><ul id="toc_lst_NBK542937_toc_ch2" class="simple-list toc bktoc_lst_exp"><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch2_s1"><a class="toc-item" href="/books/n/op0533/ch2/#ch2.s1">Background and Rationale</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch2_s2"><a class="toc-item" href="/books/n/op0533/ch2/#ch2.s2">Patient Group Input Summary</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch2_s3"><a class="toc-item" href="/books/n/op0533/ch2/#ch2.s3">Objectives</a></li></ul></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch3"><a class="toc-item" href="/books/n/op0533/ch3/">Policy Questions</a><ul id="toc_lst_NBK542937_toc_ch3" class="simple-list toc bktoc_lst_exp"><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch3_s1"><a class="toc-item" href="/books/n/op0533/ch3/#ch3.s1">Policy Question 1</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch3_s2"><a class="toc-item" href="/books/n/op0533/ch3/#ch3.s2">Policy Question 2</a></li></ul></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch4"><a class="toc-item" href="/books/n/op0533/ch4/">Research Questions</a><ul id="toc_lst_NBK542937_toc_ch4" class="simple-list toc bktoc_lst_exp"><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch4_s1"><a class="toc-item" href="/books/n/op0533/ch4/#ch4.s1">Research Question 1</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch4_s2"><a class="toc-item" href="/books/n/op0533/ch4/#ch4.s2">Research Question 2</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch4_s3"><a class="toc-item" href="/books/n/op0533/ch4/#ch4.s3">Research Question 3</a></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch4_s4"><a class="toc-item" href="/books/n/op0533/ch4/#ch4.s4">Research Question 4</a></li></ul></li><li class="half_rhythm" id="toc_itm_NBK542937_toc_ch5"><a class="toc-item" href="/books/n/op0533/ch5/">Methods &#x02014;
