Full title: Joint BTS‑BCS Guideline for Cardiovascular Assessment of Potential Adult Kidney‑Transplant Recipients ‑‑ Focus on Invasive Coronary Angiography (ICA) and Elective Coronary Revascularisation Issuing bodies：British Transplantation Society (BTS) + British Cardiovascular Society (BCS)，published April 2026，UK‑national consensus guideline。 Working‑group co‑chairs：Dr Ellie Asgari (BTS), Dr Andrew Ludman (BCS)。 Grading system：1A/1B/1C/1D = strong‑level；2D = conditional‑expert‑opinion。 Core‑paradigm‑shift：abandon routine‑universal‑invasive‑coronary‑angiography for asymptomatic ESRD transplant candidates；stress‑test‑driven, multidisciplinary‑decision‑making‑centred workflowBritish Tr...。

1. Background & Rationale

Cardiovascular‑disease remains the leading cause of mortality and major‑adverse‑cardiac‑events (MACE) among end‑stage‑kidney‑disease (ESRD) patients awaiting and after kidney transplantation. Historically many transplant‑centres performed routine‑pre‑transplant‑coronary‑angiography regardless of symptoms or non‑invasive‑test‑results. Recent observational‑cohorts show that routine‑pre‑emptive‑revascularisation in asymptomatic candidates does not consistently reduce transplant‑peri‑operative or long‑term cardiac‑mortality, and carries procedural‑risks (contrast‑AKI, vascular‑complications) in advanced‑CKD/ESRD patientsPMC.

This 2026 BTS‑BCS joint‑guideline establishes risk‑stratified pathways for coronary‑work‑up；it restricts invasive‑coronary‑angiography and elective‑revascularisation to well‑selected‑subgroups, and mandates multi‑professional‑transplant‑MDT governance for every‑high‑risk‑candidateBritish Tr....

2. Core‑definition & pre‑test‑work‑up pathway

Initial‑non‑in‑vasive‑cardiac‑screening (mandatory prior‑to‑considering‑ICA)

All potential adult kidney‑transplant candidates receive baseline： 1. Clinical‑history：angina‑equivalent‑symptoms, diabetes‑mellitus, prior‑CAD, smoking, dyslipidaemia, peripheral‑artery‑disease； 2. 12‑lead‑ECG； 3. Transthoracic‑echocardiogram (LV‑ejection‑fraction, wall‑motion‑abnormalities, valvular‑lesions, pulmonary‑artery‑pressure‑estimation)； 4. If high‑risk features exist (DM, known‑prior‑CAD, reduced‑exercise‑capacity): functional‑stress‑imaging (stress‑echocardiography / myocardial‑perfusion‑imaging) is required before proceeding‑to‑invasive‑angiographyBritish Tr....

Key‑rule‑1B: Invasive‑coronary‑angiography shall only be offered after non‑in‑vasive‑stress‑testing fails to deliver a definitive listing‑decision；do NOT‑skip non‑in‑vasive‑work‑up directly to coronary‑angiography British Tr...[1B].

3. Recommendations for invasive coronary angiography (ICA)

✅ Indications to consider elective‑in‑vasive‑coronary‑angiography (conditional‑1B)

Only proceed to ICA when all‑the‑following‑criteria‑are‑satisfied： 1. Non‑in‑vasive‑stress‑imaging demonstrates moderate‑to‑severe‑inducible‑myocardial‑ischaemia； 2. The transplant‑multidisciplinary‑team (transplant‑nephrologist + transplant‑cardiologist + cardiac‑imaging‑specialist) formally documents that angiography result will alter transplant‑listing‑strategy (either delay‑listing, require‑pre‑transplant‑revascularisation, or de‑list‑candidate due to prohibitive‑coronary‑disease)； 3. Shared‑patient‑consent obtained after discussion of procedural‑risks：contrast‑induced‑acute‑kidney‑injury, access‑site‑vascular‑complications, stroke, minor‑bleeding British Tr...[1B].

❌ Strong‑negative‑recommendation [1A]

Do NOT‑perform‑routine‑elective‑in‑vasive‑coronary‑angiography for asymptomatic kidney‑transplant‑candidates solely as a blanket‑pre‑transplant‑screen [1A]British Tr.... - Absence‑of‑angina/angina‑equivalent‑symptoms alone is not sufficient‑reason‑to‑proceed‑to‑ICA； - Isolated‑diabetes‑mellitus, age >65 years, or‑history‑of‑smoking do not automatically trigger‑in‑vasive‑angiography.

Procedural‑timing‑recommendation [1D]

If ICA is indicated: perform angiography as soon‑as‑clinically‑feasible. Balance urgency of transplant‑waiting‑list position；for pre‑emptive‑kidney‑transplant candidates, coordinate timing relative to planned‑dialysis‑initiation British Tr...[1D].

Important‑warning: Coronary‑angiography‑must‑never‑be‑ordered‑as‑a‑“blanket‑rule” for all‑diabetic‑ESRD‑candidates；every‑order‑requires documented‑MDT‑justification.

4. Elective‑coronary‑revascularisation: PCI vs CABG in transplant‑candidates

Recommendation‑1B: Elective‑coronary‑revascularisation indications in potential‑kidney‑transplant‑recipients follow the same clinical thresholds used for non‑transplant‑patients British Tr...[1B].

Clinical‑scenarios where revascularisation should‑be‑considered (conditional‑1B)

1. Left‑main‑coronary‑artery‑significant‑stenosis (≥50 %‑stenosis)； 2. Multi‑vessel‑coronary‑artery‑disease with severe‑in‑ducible‑ischaemia and reduced‑LV‑systolic‑function； 3. Persistent‑symptomatic‑angina despite optimal‑medical‑anti‑ischaemic‑therapy (OMT)； 4. Revascularisation‑decision must be agreed‑within the joint‑cardiac‑transplant‑MDT.

Revascularisation‑modality‑selection principles

1. Percutaneous‑coronary‑intervention (PCI) - Drug‑eluting‑stent (DES) is generally‑preferred‑for most‑transplant‑candidates； - If‑transplant‑surgery‑is‑planned‑very‑shortly‑after‑stenting: balance‑dual‑anti‑platelet‑therapy (DAPT)‑duration‑versus‑bleeding‑risk‑during‑transplant‑operation； - Short‑duration‑DAPT‑strategies may‑be‑individualised‑within‑MDT‑agreement for urgent‑transplant‑candidates. 2. Coronary‑artery‑bypass‑grafting (CABG) - Consider‑CABG‑for‑complex‑multi‑vessel‑CAD, especially‑when‑LV‑dysfunction‑co‑exists； - Surgical‑risk‑stratification is critical: ESRD‑patients carry‑higher‑peri‑operative‑surgical‑mortality‑risk‑for‑open‑cardiac‑surgery.

Strong‑caution‑statement

Do NOT‑perform‑elective‑revascularisation‑purely‑“to‑get‑ready‑for‑transplant” in‑asymptomatic‑patients merely‑based‑upon‑angiographic‑stenosis‑without‑objective‑evidence‑of‑ischaemia [1A]British Tr.... Optimal‑medical‑therapy (OMT) is the default‑strategy for asymptomatic‑candidates with‑stenosis‑but‑no‑ischaemia‑signs.

5. Multidisciplinary‑MDT‑mandate (central‑requirement of this guideline)

All candidates with abnormal‑cardiac‑tests (abnormal‑stress‑test, significant‑wall‑motion‑defect‑on‑echo) must‑be‑discussed‑within joint‑cardiac‑transplant‑multidisciplinary‑meeting [2D]British Tr.... MDT‑membership should include: - Transplant‑nephrologist - Specialist‑renal‑cardiologist - Cardiac‑imaging‑physician - Transplant‑co‑ordinator - Cardiac‑surgeon‑input‑when‑CABG‑is‑under‑consideration.

MDT‑must‑document: - Rationale‑for‑or‑against‑coronary‑angiography； - Rationale‑for‑or‑against‑pre‑transplant‑revascularisation； - Impact‑upon‑transplant‑listing‑status (delay‑listing, proceed‑to‑list, or‑de‑list‑patient).

6. Special‑populations

6.1 Diabetes‑mellitus‑ESRD‑candidates

DM is‑a‑major‑CAD‑risk‑factor but does‑not automatically‑trigger‑ICA. Must‑complete‑non‑in‑vasive‑stress‑testing‑first‑before‑any‑angiography‑decision. Many‑diabetic‑ESRD‑patients‑have‑silent‑ischaemia, hence‑stress‑imaging‑is‑mandatory‑in‑this‑group.

6.2 Pre‑emptive‑transplant‑candidates (no‑dialysis‑prior‑to‑kidney‑graft)

Same‑work‑up‑standard‑applies. Coordinate‑timing‑of‑angiography‑and‑possible‑revascularisation‑so‑that‑cardiac‑work‑up‑is‑completed‑before‑planned‑transplant‑date.

6.3 Patients‑already‑on‑active‑kidney‑transplant‑waiting‑list

If‑new‑cardiac‑symptoms‑develop‑after‑listing: re‑run‑non‑in‑vasive‑stress‑testing, then‑re‑assess‑by‑MDT‑before‑considering‑angiography.

7. Optimal‑medical‑therapy (OMT) foundational‑therapy

All‑candidates‑with‑coronary‑artery‑disease receive‑maximally‑tolerated‑OMT‑regardless‑of‑whether‑revascularisation‑is‑performed： - Statins + ezetimibe (target‑LDL‑C‑reduction‑per‑contemporary‑lipid‑guidelines)； - Anti‑platelet‑therapy (aspirin ± P2Y12‑inhibitor‑if‑stented)； - Beta‑blockers； - ACE‑I / ARB where‑haemodynamically‑tolerated； - Smoking‑cessation； - Dyslipidaemia‑control； - Blood‑pressure‑optimisation.

8. Key‑evidence‑gaps explicitly‑noted‑within‑guideline

1. Large‑randomised‑controlled‑trials‑comparing “routine‑ICA‑pre‑transplant” versus “stress‑test‑guided‑selective‑ICA” are‑still‑lacking；most‑evidence‑derives‑from‑observational‑UK‑national‑cohort‑studies； 2. Optimal‑DAPT‑duration‑in‑kidney‑transplant‑candidates‑receiving‑DES‑PCI‑immediately‑prior‑to‑transplant‑surgery‑remains‑under‑debate； 3. Head‑to‑head‑comparisons‑of‑PCI‑versus‑CABG‑specific‑for‑ESRD‑transplant‑candidates‑are‑limited‑in‑sample‑size； 4. Predictive‑biomarkers‑to‑better‑identify‑which‑asymptomatic‑ESRD‑subjects‑will‑benefit‑from‑pre‑transplant‑revascularisation‑remain‑unvalidated.

9. Take‑home‑summary statements (consensus‑core‑points)

1. 2026 BTS‑BCS‑guideline rejects‑routine‑universal‑in‑vasive‑coronary‑angiography‑for‑asymptomatic‑adult‑kidney‑transplant‑candidates (Grade 1A)British Tr.... 2. Invasive‑coronary‑angiography is‑only‑indicated‑when‑non‑in‑vasive‑stress‑imaging‑shows‑significant‑inducible‑myocardial‑ischaemia and‑MDT‑documents‑that‑the‑angiogram‑will‑change‑transplant‑listing‑management [1B]. 3. Always‑complete‑non‑in‑vasive‑cardiac‑work‑up (ECG, echo, stress‑imaging) before‑ordering‑coronary‑angiography；never‑skip‑non‑in‑vasive‑assessment. 4. Elective‑revascularisation‑(PCI/CABG) uses‑the‑same‑clinical‑thresholds‑as‑non‑transplant‑populations；avoid‑pre‑emptive‑revascularisation‑only‑for‑transplant‑eligibility‑purpose [1B]. 5. Every‑abnormal‑cardiac‑stress‑test‑must‑be‑reviewed‑in‑joint‑cardiac‑transplant‑multidisciplinary‑MDT‑meeting；documentation‑of‑MDT‑discussion‑is‑required‑[2D]. 6. Diabetes‑mellitus, age‑>65 years, or‑smoking‑history‑do‑not‑in‑themselves‑mandate‑in‑vasive‑coronary‑angiography. 7. Optimal‑medical‑anti‑ischaemic‑therapy‑is‑the‑foundation‑for‑all‑candidates‑with‑coronary‑artery‑disease, whether‑revascularised‑or‑not. 8. Revascularisation‑decisions cannot‑be‑made‑by‑cardiologist‑alone；transplant‑nephrology‑team‑must‑participate‑in‑shared‑decision‑making.
