PREAMBLE 49
50 The American College of Cardiology Foundation (ACCF) and the American Heart Association 51 (AHA) support their members’ goal to improve the prevention and care of cardiovascular 52 diseases through professional education, research, development of guidelines and standards and 53 by fostering policy that supports optimal patient outcomes. The ACCF and AHA recognize the 54 importance of the use of clinical data standards for patient management, to assess outcomes, and 55 conduct research and the importance of defining the processes and outcomes of clinical care, 56 whether in randomized trials, observational studies, registries, or quality improvement initiatives. 57 58 Hence, clinical data standards strive to define and standardize data relevant to clinical topics in 59 cardiology, with the primary goal of assisting data collection by providing a platform of data 60 elements and definitions applicable to various conditions. Broad agreement on a common 61 vocabulary with reliable definitions used by all is vital to pool and/or compare data across 62 studies and assess the applicability of research to clinical practice. The growing adoption of 63 electronic medical records renders even more imperative and urgent the need for such definitions 64 and standards. Therefore, the ACCF and AHA have undertaken to define and disseminate 65 clinical data standards—sets of standardized data elements and corresponding definitions to 66 collect data relevant to cardiovascular conditions. The ultimate purpose of clinical data 67 standards is to contribute to the infrastructure necessary for accomplishing the ACCF/AHA’s 68 mission of fostering optimal cardiovascular care and disease prevention. 69 70 The specific goals of clinical data standards are: 71 1. to facilitate the establishment of registries and quality improvement programs by providing a 72 list of major variables, outcomes, and definitions. 73 2. to optimize the comparison of results and outcomes across registries and studies 74 3. to become the basis for a standardized medical documentation process, essential for the 75 electronic medical record environment. 76 77 The key elements and definitions are a compilation of variables to measure patient management 78 and outcomes for clinical and research purposes as well as for quality improvement in order to 79 standardize the language used to describe cardiovascular diseases and procedures, enhance 80 consistency in cardiology, and increase opportunities for sharing data across data sources. The 81 ACCF/AHA Task Force on Clinical Data Standards selects cardiovascular conditions and 82 procedures that will benefit from creating a data standard set. Experts in the subject are selected 83 to examine/consider existing standards and develop a comprehensive, yet not exhaustive, data 84 standard set. When undertaking a data collection effort, only a subset of the elements contained 85 in a clinical data standards listing may be needed or, conversely, users may want to consider 86 whether it may be necessary to collect some elements not listed. For example, in the setting of a 87 randomized clinical trial of a new drug, additional information would likely be required 88 regarding study procedures and drug therapies. 89 90 The Health Insurance Portability and Accountability Act (HIPAA) privacy regulations, which 91 went into effect in April 2003, have heightened all practitioners’ awareness of our professional 92 commitment to safeguard our patients’ privacy. The HIPAA privacy regulations 93

(http://www.hhs.gov/ocr/combinedregtext.pdf, page 31) specify which information elements are 94 considered “protected health information.” These elements may not be disclosed to third parties 95 (including registries and research studies) without the patient’s written permission. Protected 96 health information may be included in databases used for health care operations under a data use 97 agreement. Research studies using protected health information must be reviewed by an 98 institutional review board or a privacy board. 99 100 We have included identifying information in all clinical data standards to facilitate uniform 101 collection of these elements when appropriate. For example, a longitudinal clinic database may 102 contain these elements, since access is restricted to the patient’s caregivers. On the other hand, 103 registries may not contain protected health information unless specific permission is granted by 104 each patient. These fields are indicated as protected health information in the data standards. 105 106 The ACCF/AHA Task Force on Clinical Data Standards makes every effort to avoid any actual 107 or potential conflicts of interest that may arise as a result of an outside relationship or a personal, 108 professional, or business interest of a member of the writing panel. Specifically, all members of 109 the writing group were required to submit a disclosure form showing all such relationships that 110 might be perceived as real or potential conflicts of interest. These statements are reviewed by the 111 ACCF/AHA Task Force on Clinical Data Standards, reported orally to all members of the 112 writing panel at the first meeting, and updated as changes occur. Writing Committee members’ 113 relationships with industry are listed in Appendix A. Relationships with industry for official peer 114 reviewers are listed in Appendix B. 115 116 In clinical care, caregivers communicate with each other through a common vocabulary. In an 117 analogous fashion, the integrity of clinical research depends on firm adherence to pre-specified 118 procedures for patient enrollment and follow-up; these procedures are guaranteed through careful 119 attention to definitions enumerated in the study design and case-report forms. When data 120 elements and definitions are standardized across studies, comparison, pooled analysis, and meta-121 analysis are enabled, thus deepening our understanding of individual studies. 122 123 The recent development of quality performance measurement initiatives, particularly those for 124 which comparison of providers is an implicit or explicit aim, has further raised awareness about 125 the importance of data standards. Indeed, a wide audience, including non-medical professionals 126 such as payers, regulators, and consumers, may draw conclusions about care and outcomes. To 127 understand and compare care patterns and outcomes, the data elements that characterize them 128 must be clearly defined, consistently used, and properly interpreted, now more than ever before. 129 130 131 132

I. INTRODUCTION 135
136 Atherosclerotic vascular disease refers to disorders of arteries of caused by atherosclerosis (1). 137
This document provides clinical data standards for peripheral atherosclerotic vascular diseases 138
including lower extremity peripheral artery disease, abdominal aortic aneurysm, renal and 139
mesenteric artery disease, and extracranial carotid artery disease. It may serve as a companion to 140
the ACCF/AHA Guideline Statement of Peripheral Arterial Diseases(2) and the ACCF/AHA 141
Performance Measures for Peripheral Arterial Disease(3). Coronary artery disease is outside the 142
scope of this document. Multiple disciplines are engaged in the evaluation and management of 143
patients with peripheral atherosclerotic vascular diseases and developments in relevant research 144
and technology are emerging rapidly. Therefore, in order to ensure optimal documentation and 145
communication among health care providers, researchers, policy makers, payers, and industry, 146
the establishment of a uniform set of data elements and definitions for peripheral atherosclerotic 147
vascular diseases could not be more timely and compelling. 148
149
The data standards covered in this document are divided into six distinct tables. The first covers 150
general data elements that are common to all peripheral atherosclerotic vascular diseases. This 151
includes demographic information, atherosclerotic risk factors, concurrent atherosclerotic 152
diseases, comorbid conditions, medications, the cardiovascular examination, and relevant blood 153
chemistries and hematology. The remaining tables cover data standards that are specific for 154
lower extremity peripheral artery disease, abdominal aortic aneurysm, renal artery disease, 155
mesenteric artery disease, and extracranial carotid artery disease, respectively. Each of the 156
disease specific tables includes the following data elements: medical history; physical 157
examination; laboratory testing; diagnostic procedures; invasive therapeutic procedures (both 158
endovascular and open surgical); pharmacologic therapy; follow-up; and outcomes. 159

II. METHODOLOGY 161
A. Writing Committee Composition 162
163 The ACCF/AHA Task Force on Clinical Data Standards selected members for the Writing 164
Committee to Develop Clinical Data Standards for Peripheral Atherosclerotic Vascular Disease 165
(Writing Committee). The Writing Committee consisted of 23 members who are well versed in 166
the epidemiology, clinical evaluation, medical management, invasive therapy, and/or outcome 167
assessment of patients with vascular disease and included individuals with expertise in patient 168
care, clinical investigation, and health services research and delivery. The Writing Committee 169
included representatives from a broad range of cardiovascular professional societies and 170
organizations, to ensure that the content of this document is widely applicable. All organizations 171
listed on the masthead and collaborating organizations nominated individuals to comprise the 172
makeup of the Writing Committee. 173
B. Relationships with Industry 174
175 The ACCF/AHA Task Force makes every effort to avoid any actual or potential conflicts of 176
interest that may arise as a result of an outside relationship or a personal, professional, or 177
business interest of a member of the writing panel. Specifically, all members of the writing group 178
were required to complete and submit a disclosure form showing all such relationships that might 179
be perceived as real or potential conflicts of interest. These statements are reviewed by the 180
ACCF/AHA Task Force on Clinical Data Standards and are updated when changes occur. Please 181
see Appendix A for the Writing Committee relationships with industry. 182
C. Review of Literature and Existing Data Definitions 183

The PAVD Data Standards are intended to provide data elements that parallel and complement 185
existing data fields as previously reported in ACCF and AHA clinical data standards 186
documents(4-8), along with those used as fields within existing registries, such as those 187
developed by the ACC National Cardiovascular Data Registry (NCDR)(9). We also reviewed the 188
ACCF/AHA 2007 Methodology for Development of Clinical Data Standards(10), the Reporting 189
standards formulated by the Society for Vascular Surgery/International Society for 190
Cardiovascular Surgery, the National Heart Lung and Blood Institute (NHLBI) Claudication: 191
Exercise versus Endoluminal Revascularization (CLEVER)(11, 12) and Cardiovascular Outcome 192
in Renal Atherosclerotic Lesions (CORAL) trials(13, 14). 193
D. Defining Data Elements 194
195 The data elements were developed by the Writing Committee in a way that the definitions were 196
broad enough for use in various aspects of data collection, but specific enough to promote 197
uniform and simplified interpretation of data. Some elements will require an additional level of 198
specificity by the end-user for implementation which is beyond the scope of the Writing 199
Committee. Data definitions were linked whenever possible to the evidence-based national 200
guidelines. 201
To ensure consistency across ACCF/AHA clinical data standards, writers used an 202
existing ACCF/AHA definition. The Writing Committee chose not to develop an all-inclusive 203
list of every possible data element that may be used for all aspects of Peripheral Atherosclerotic 204
Vascular Disease. Rather, the Writing Committee focused its attention on common elements that 205
cross vascular specialty disciplinary boundaries. It is anticipated that some data definitions and 206
elements will need further delineation, likely by subspecialty society organizations and groups. 207

The purpose of this document is to attempt to harmonize as many common data fields as 208
possible. 209
E. Relation to Other Standards 210
211 The Writing Committee reviewed other standards including those developed for heart failure, 212
atrial fibrillation, electrophysiology, acute coronary syndromes, and cardiac imaging, as 213
previously noted. It was felt that this Writing Committee possessed key levels of expertise 214
needed to address issues regarding Peripheral Atherosclerotic Vascular Disease in a consistent 215
fashion. 216
F. Consensus Development 217
218 These ACCF/AHA data standards, like others, are team-developed and written 219
documents and are based on the judgments of experts. The Writing Committee met more than 10 220
times, by telephone and in person, over the course of 3.5 years to define and refine the data 221
elements. Throughout the process, consensus was developed through extensive in-person 222
discussion, teleconferences, and e-mails. 223
G. Peer Review, Public Review, and Board Approval 224
225
The set of PAVD standards and definitions was independently reviewed by official appointees 226
from the ACC, AHA, ACR, SCAI, SIR, SVMB, SVN, ACCF/AHA Data Standards Task Force 227
as well as experts from collaborating organizations namely ACP, AACPR, AAN, ADA, NHLBI, 228
PAD SAI-P, SCCT, SCMR and VDF. To increase its applicability, this document was posted on 229
the ACC Website for a 30-day public comment period from September 1, 2010 through October 230
1, 2010. The document was then approved by all sponsoring organizations on __________. 231
2010 PAVD Data Standards CONFIDENTIAL DRAFT August 24, 2010

10
The Writing Committee anticipates these data standards will require review and updating, 232
just as with guidelines, performance measures and appropriateness criteria. At the anniversary of 233
the data standards publication, the Writing Committee will review the data standards to ascertain 234
whether or not modifications should be considered. 235
H. Considerations for Peripheral Atherosclerotic Vascular Disease Data Standards 236
237 The Writing Committee anticipates that the Peripheral Atherosclerotic Vascular Disease Data 238
Standards will prove useful in several settings: 239
1. Clinical Programs where providers and health plans work in concert to achieve 240
optimal utilization of procedures pertaining to PAVD. Data standards will assist 241
in the development of structured reporting systems, organizing and designing of 242
electronic medical information systems including clinical data-basing and 243
decision support tools. 244
2. Clinical Research including prospective registries and randomized controlled 245
trials. Meta-analyses will be particularly strengthened by the use of standardized 246
data for key variables. 247
3. Quality Assessment/Performance Measurement. Data standards will 248
especially facilitate interpretation for nonmedical users, including payers, 249
regulators, and consumers. 250

ECG changes indicative of new ischemia (new ST-T changes, new
left bundle branch block, or loss of R- wave voltage), c. Development of pathological Q- waves in 2 or more contiguous
leads in the ECG (or equivalent findings for true posterior MI); d. Imaging evidence of new myocardial infarction or new regional
wall motion abnormality; e. Documentation in the medical record of the diagnosis of acute
myocardial infarction based on the cardiac biomarker pattern in the absence of any items enumerated in a-d due to conditions that may mask their appearance (e.g., peri-operative infarct when the patient cannot report ischemic symptoms; baseline left bundle branch block or ventricular pacing)
• ECG changes associated with prior myocardial infarction can include the following (with or without prior symptoms): a. Any Q-wave in leads V2-V3 >=0.02 seconds or QS complex in
leads V2 and V3. b. Q-wave >=0.03 seconds and >=0.1 mV deep or QS complex in
leads I, II, aVL, aVF, or V4-V6 in any two leads of a contiguous lead grouping (I, aVL, V6; V4-V6; II, III, and aVF).
c. R-wave >=0.04 seconds in V1-V2 and R/S >=1 with a concordant positive T-wave in the absence of a conduction defect.
• Imaging evidence of a region with new loss of viable myocardium at rest in the absence of a non-ischemic cause. This can be manifest as: a. Echocardiographic, CT, MR, ventriculographic or nuclear imaging
evidence of left ventricular thinning or scarring and failure to contract appropriately (i.e., hypokinesis, akinesis, or dyskinesis)
b. Fixed (non-reversible) perfusion defects on nuclear radioisotope imaging (e.g., MIBI, thallium)

344 In the context of this document, extracranial carotid artery disease is defined as a cerebral artery 345
atherosclerotic disease that causes stenosis or occlusion of the cervical portion of the carotid 346
arteries(1). Other causes of carotid artery disease include fibromuscular dysplasia, arteritis, 347
radiation-induced arteriopathy, dissection and restenosis following carotid artery 348
revascularization procedures. Extracranial vertebral and intracranial cerebral artery diseases are 349
outside the scope of this document. The data elements defined in Table 6 include symptoms and 350
clinical findings related to ischemic strokes and transient ischemic attacks that occur in patients 351
with carotid artery disease. Also included are data elements which define anatomic high risk 352
conditions and comorbid cardiopulmonary conditions that are used to assess risk of carotid 353
revascularization procedures. Table 6 provides detailed elements of carotid artery imaging tests 354
including duplex ultrasonography, magnetic resonance angiography, computed tomographic 355
angiography, and catheter-based angiography, In addition, there are detailed data elements for 356
carotid artery stenting including specific elements concerning the procedure, target lesion 357
location, results and complications, and similarly for carotid endarterectomy. In addition, data 358
elements are defined for clinical outcomes following carotid revascularization. 359
