HCCAR005 — Synthetic Coronary Artery Disease Dataset (Sample Preview)

XpertSystems.ai | Synthetic Data Factory | Healthcare / Cardiology Vertical

A longitudinal coronary artery disease (CAD) patient dataset spanning the full spectrum from subclinical disease through acute coronary syndromes through post-revascularization follow-up. 150 patients across 7 CAD stages (Subclinical, Stable Angina, Unstable Angina, NSTEMI, STEMI, Post-PCI, Post-CABG) followed annually for 10 years — yielding 1,500 visit-level records with 140 features per row covering:

CAD anatomy (3-vessel stenosis %, FFR per vessel + iFR, SYNTAX score, plaque burden, lesion length, MLA, Agatston calcium score, plaque type including TCFA)
Angina assessment (CCS class, angina frequency/duration/trigger, nitroglycerin response, NYHA functional class, Seattle Angina Questionnaire 5 domains, Duke treadmill score, stress test results
- modality)
ACS events (door-to-balloon, TIMI flow pre/post, thrombus burden, Killip class, GRACE score, TIMI risk score)
Biomarkers (Troponin I/T, CK-MB, BNP/NT-proBNP, CRP, visit-level LDL/HDL/Trig with statin effect)
Interventions (PCI with DES_EES/BMS, stent type/length/diameter, num_stents, post-PCI FFR/MLA, contrast volume, radiation dose; OR CABG with graft count, LIMA usage, pump time, cross-clamp time; procedural success flag)
Imaging (echo LVEF/LVEDV/LVESV, RWMA + territory, E/e', LAVI; CCTA plaque volume + napkin-ring sign; nuclear stress SSS/SDS)
Medications (DAPT with P2Y12 selection and duration, statin intensity, beta-blocker, ACEi/ARB, SGLT2i, PCSK9i, anticoagulant)
Outcomes (MACE flag + component, time-to-MACE, target vessel revascularization, in-stent restenosis, graft patency, 30-day readmission, CV death, all-cause mortality, LVEF change)

Calibrated benchmark-first against ACC/AHA Stable CAD Guidelines (Fihn et al.), SYNTAX Trial (Mohr et al., Serruys et al.), COURAGE (Boden et al.), ISCHEMIA Trial (Maron et al. 2020), FREEDOM Trial (Farkouh et al.), 4th Universal Definition of MI (2018), Killip-Kimball (1967), NCDR ACTION + CathPCI Registries, STS Adult Cardiac Surgery Database, GRACE Registry (Granger et al. 2003), TIMI Risk Score (Antman et al. 2000), Seattle Angina Questionnaire (Spertus et al. 1995), and KDIGO 2012 CKD staging.

This is the sample preview — 150 patients × 10 annual visits over 10 years (1,500 visit records, ~1.1 MB). The full product covers 10,000+ patients with extended procedural detail, full medication titration trajectories, multi-imaging modality co-occurrence, and pre-built scenario configs for ISCHEMIA replication, FREEDOM DM-CAD cohort, COURAGE invasive vs OMT, EXCEL-style left-main PCI-vs-CABG, and BIOFLOW-V stent comparison studies.

Limitations and honest disclosures

This sample is calibrated for structural fidelity, not bit-exact reproduction of any specific CAD registry archive. Specifically:

Visit-level outcomes (MACE, mortality, ISR, graft patency, readmission) are FRESH RANDOM SAMPLES per visit, NOT cumulative carry-forward. The same patient can have mace_event_flag=1 at visit 3 and mace_event_flag=0 at visit 7 (with the visit 3 event implicitly recovered from). For patient-level event analysis, use groupby('patient_id').max() on the binary outcome flags.
MACE per-visit rate (~13-14%) compounds over 10 visits to very high cumulative rates — patient-level any-MACE will exceed real-world CAD cohort 5-year MACE (~15-25%). Disclosed; for absolute-rate calibration use the full product or scale down per-visit hazard.
Imaging (echo LVEF, RWMA, CCTA, nuclear stress) is computed for ALL visits regardless of clinical indication. In real practice, serial imaging is reserved for clinical change or pre-procedure planning. Treat as "what the result would be if imaging were performed."
Patient baseline is FIXED at visit 1 (cad_stage, comorbidities, intervention_arm, baseline lipids, baseline anatomy). The generator does NOT model CAD progression to higher-stenosis or stage transitions longitudinally. For genuine CAD progression ML, augment with a trajectory model.
ACS events fire ONLY at visit 1 (the index visit). The generator does NOT model NEW ACS events at later visits — every visit_number > 1 has acs_type = 'None'. For longitudinal ACS incidence ML, use the full product or augment with a recurrent-event model.
Stent fields are populated ONLY at visit 1 for PCI patients. They are NOT carried forward to follow-up visits — stent_type, stent_length_mm, num_stents_deployed, post_pci_ffr are all NaN at visits 2-10 even for PCI patients. For longitudinal PCI follow-up modeling, join the visit-1 stent data to all subsequent visits manually.
CABG fields similarly populated only at visit 1, and the Hybrid intervention arm goes through the PCI path in the generator (so cabg_grafts is NaN for Hybrid patients despite the arm label including "CABG").
The generator has a hasattr(p, 'angina_class_ccs') check in the imaging module (line 505) that ALWAYS returns False because p is a dict (not an object with attributes). So nuclear_sss calculation never incorporates CCS — it always falls through to the default N(10, 6) distribution. Disclosed; if SSS-vs-CCS correlation matters for your ML, augment.
eGFR uses a simplified formula — the lambda creatinine = clip(9.5 / egfr, 0.5, 5.0) (line 112) is the INVERSE derivation (creatinine from eGFR, not eGFR from creatinine). It is approximately correct (consistent with simplified CKD-EPI without sex/age/race), but NOT the full published formula. For accurate eGFR research, recompute from creatinine + age + sex + race using the modern 2021 NKF-ASN refit.
HCCAR005 lacks racial/ethnic information — the generator does not assign race/ethnicity (unlike HCCAR001 / HCCAR003 / HCCAR004). Disparities research will need augmentation.
GRACE score formula is simplified — the generator uses grace = 20 + age*1.4 + killip*10 + (30 if STEMI) + ck*8 (line 330) as an approximation, NOT the full Granger et al. 2003 logistic regression with all 8 published variables. Values are in the published range [0, 372] but absolute calibration differs from GRACE 2.0. Use for relative risk stratification, not absolute in-hospital mortality probability.
Statin lipid effect is FIXED at 50% LDL reduction for non-OMT patients and 15% for OMT patients (line 382). Real-world response varies widely (Rosuvastatin 40mg ~55%, Atorvastatin 80mg ~52%, Pravastatin 20mg ~24%). The statin_intensity field (None / Low / Moderate / High) is randomly assigned and NOT linked to the LDL reduction magnitude. For statin response ML, augment with intensity- specific effects.
PCSK9i prescribing is independent of LDL response in the generator. Real-world PCSK9i is reserved for patients failing to reach LDL goals on maximally tolerated statin + ezetimibe. The generator fires pcsk9_inhibitor_flag at 15% baseline rate if LDL > 100, ignoring statin trial.
Time-to-MACE is a Weibull sample with shape=1.8, scale=2000 days (line 598), NOT linked to actual visit when MACE was flagged. Use the visit-level mace_event_flag for incident analysis, not time_to_mace_days for survival models.
CSV serialization converts None to NaN when reading via pd.read_csv default behavior. Use keep_default_na=False or work with the Parquet file (which preserves nullable types correctly).
ISCHEMIA / COURAGE eligibility is NOT enforced — the generator produces a heterogeneous CAD cohort. Filter to your own inclusion criteria for trial-replication ML.

The full HCCAR005 product addresses these by genuine CAD progression modeling (stenosis evolution, stage transitions), longitudinal stent carry-forward, recurrent ACS event modeling, full CKD-EPI 2021 formula, race/ethnicity assignment with disparities encoding, intensity-specific statin response curves, PCSK9i trial-stepped prescribing, and pre-built scenario configs (ISCHEMIA replication, COURAGE invasive-vs-OMT, FREEDOM DM-CAD, EXCEL left-main PCI-vs-CABG, BIOFLOW-V stent comparison).
