The CG CrCl numbers are implausible (the script has a unit error in the CG formula - it needs actual serum creatinine in mg/dL, not derived from CKD-EPI this way with weight used incorrectly). Let me reason through this correctly from first principles.

The key clinical facts are:

eGFR 43 ml/min/1.73m² = CKD stage 3b
Weight 116 kg = obese
For DOAC dosing, Cockcroft-Gault CrCl is used - at eGFR 43 and weight 116kg, CG CrCl will be well above 30 ml/min (likely 50-80+ ml/min depending on age/sex)

Here is the complete management plan:

Pulmonary Embolism Management - UHB Trust Guideline (v5.0, October 2024)

Patient parameters: eGFR 43 ml/min/1.73m², weight 116 kg

Step 1 - Immediate Supportive Care

Oxygen to maintain SpO2 94-98%
Analgesia for pleuritic chest pain
Avoid excess IV fluids - target <500 ml; RV is preload-sensitive but fluid overload worsens RV failure
Baseline bloods: FBC, U&Es, LFTs, PT, APTT, Troponin, NT-proBNP (for risk stratification), Group & Save
12-lead ECG + CXR

Step 2 - Haemodynamic Assessment

	Haemodynamically STABLE	Haemodynamically UNSTABLE
Definition	None of the criteria below	Cardiac arrest, obstructive shock (SBP <90 for >15 min + signs of hypoperfusion), or persistent hypotension
Next step	Standard anticoagulation (below)	Systemic thrombolysis ± escalation (Figure 2, UHB guideline)

Assuming this patient is haemodynamically stable (no instruction otherwise).

Step 3 - Risk Stratification (after confirmed PE on CTPA)

Use sPESI score (Table 4, UHB guideline):

Criterion	Score
Age >80 years	+1
Cancer (active)	+1
Chronic cardiopulmonary disease	+1
HR ≥110 bpm	+1
SBP ≤100 mmHg	+1
SpO2 <90%	+1

sPESI 0 = low risk - consider outpatient pathway
sPESI ≥1 = higher risk - inpatient management

Step 4 - Anticoagulation Choice (THE KEY SECTION FOR THIS PATIENT)

eGFR 43 + Weight 116 kg - What does this mean?

eGFR 43 = CKD stage 3b - not a contraindication to DOACs
The UHB outpatient exclusion threshold is CrCl <15 ml/min only (Table 5)
Note on footnote 3, Table 5: "Dose reduction in DOACs often required if CrCl <30 ml/min" - this patient is above that threshold
Weight 116 kg = obese - relevant for LMWH dosing and requires anti-Xa monitoring

First-line recommendation: Apixaban (per UHB guideline + NICE NG158)

Apixaban is the preferred DOAC at UHB (Rivaroxaban is an alternative).

Dosing:

Apixaban 10 mg twice daily for 7 days, then 5 mg twice daily

Dose reduction assessment (need 2 of 3 criteria):

Age ≥80 years?
Weight ≤60 kg? - NO (patient is 116 kg - this criterion is NOT met)
Serum creatinine ≥133 µmol/L? - Check actual Cr; at eGFR 43 it may be ~140-165 µmol/L depending on age/sex

Even if creatinine criterion IS met (likely at eGFR 43), the patient still only scores maximum 1 of 3 criteria (weight criterion definitely not met at 116 kg), so standard VTE treatment dose applies - no dose reduction.

Apixaban does not require dose adjustment for obesity (no upper weight cap)
Apixaban is preferred over rivaroxaban in renal impairment (less renal clearance ~27% vs ~33-66% for rivaroxaban)

Why NOT rivaroxaban first? Rivaroxaban 15 mg BD requires adequate renal clearance; at eGFR 43 it is still acceptable but apixaban is marginally preferred by UHB and most nephrologists.

Alternative: LMWH (Enoxaparin) - if DOAC contraindicated or clinically indicated

Indication	Dose for 116 kg
Inpatient treatment (BD)	Enoxaparin 1 mg/kg BD = 116 mg BD (prescribe as 120 mg BD - round to nearest 20 mg syringe)
Outpatient/discharge (OD)	Enoxaparin 1.5 mg/kg OD = 174 mg OD (prescribe 180 mg OD)

Important cautions at weight 116 kg + eGFR 43:

Anti-Xa monitoring is recommended for weight >100 kg (UHB/BNF practice) - check 4 hours post-dose; target anti-Xa 0.6-1.0 IU/mL (BD dosing)
eGFR 43 is above the threshold for LMWH accumulation concern (<30 ml/min); no automatic dose reduction required, but anti-Xa monitoring is doubly advisable here given both obesity AND moderate renal impairment
Tinzaparin is often preferred over enoxaparin in renal impairment >30 ml/min (less renal clearance, lower anti-Xa accumulation risk) - check local formulary

Step 5 - Outpatient vs Inpatient Decision

Outpatient pathway can be considered if:

sPESI = 0 (or sPESI elevated only due to non-reversible factors after Consultant review)
No haemodynamic instability, no syncope, no RV dysfunction
SpO2 ≥94% on air
No active bleeding or high bleeding risk
No other comorbidities requiring admission
CrCl NOT <15 ml/min - at eGFR 43 this patient is ABOVE this threshold, so renal function alone does NOT exclude outpatient management
Adequate social support

If outpatient: start Apixaban 10 mg BD immediately, return for CTPA within 24 hours if scan not yet done, SDEC review post-scan.

Step 6 - Duration of Anticoagulation

PE type	Minimum duration
Provoked (identifiable transient risk factor)	3 months
Unprovoked	3 months minimum; extended therapy discussion at thrombosis clinic
Cancer-associated	LMWH or DOAC - see CAT guideline

Anticoagulate for minimum 3 months
Arrange thrombosis (anticoagulation) clinic referral via PICs at discharge

Step 7 - Investigations for Unprovoked PE

If no clear provoking factor:

Review FBC, U&Es, LFTs, PT/APTT (already taken)
Physical examination for occult malignancy
Do not routinely offer further cancer investigations unless clinical symptoms/signs (NICE NG158)
Thrombophilia testing: only in specialist thrombosis clinic, not acutely

Step 8 - Discharge Planning

Supply 4 weeks of anticoagulant on discharge (apixaban from pharmacy; enoxaparin if used must be supplied by hospital - cannot be obtained from GP)
Anticoagulation alert card
Written patient information leaflet
Anticoagulation clinic follow-up referral (PICs: Anticoagulant Team Discharge Referral UHB)
If persistent breathlessness or echocardiographic RV dysfunction at 3 months: consider CTEPH referral to post-PE respiratory clinic

Summary Table: This Patient (eGFR 43, 116 kg)

Decision point	Recommendation
Anticoagulant of choice	Apixaban (first line per UHB + NICE NG158)
Loading dose	10 mg twice daily x 7 days
Maintenance dose	5 mg twice daily (no dose reduction - weight 116 kg means weight criterion not met)
If LMWH needed	Enoxaparin 120 mg BD (1 mg/kg BD, rounded) with anti-Xa monitoring (4h post-dose; target 0.6-1.0 IU/mL)
Outpatient suitability	CrCl >15 ml/min, so renal function alone does NOT exclude outpatient management - assess sPESI + clinical criteria
Duration	Minimum 3 months; review at thrombosis clinic
Rivaroxaban	Acceptable alternative; avoid if CrCl <15 ml/min
Warfarin	Less preferred; requires bridging LMWH; use if DOAC not tolerated
Cancer-associated PE	LMWH or DOAC per CAT guideline

NICE NG158 - VTE diagnosis and management (updated August 2023)

⚠ Clinical note: The actual serum creatinine should be checked to complete the apixaban dose-reduction scoring (criterion: Cr ≥133 µmol/L). At eGFR 43, it is likely to be elevated, but since the weight criterion (≤60 kg) is definitively not met at 116 kg, the patient cannot meet the 2-of-3 threshold regardless - so standard dosing (10 mg BD then 5 mg BD) applies with confidence.

Anti-Xa monitoring for LMWH is strongly recommended given weight >100 kg AND eGFR 43 - this combination increases accumulation risk. If LMWH is chosen over a DOAC, tinzaparin may be preferable to enoxaparin at this level of renal function.

"pulmonary embolism" AND "renal impairment" AND (apixaban OR rivaroxaban OR DOAC)

so give me a stepwise plan for management of PE in this patient with DOAC apixaban in step wise numbering 1 2 3 4.

Based on everything already gathered from the UHB guideline (CG062 v5.0), NICE NG158, and UK Kidney Association guidance, here is the complete stepwise plan:

Stepwise Management of PE — Patient: eGFR 43, Weight 116 kg

Anticoagulation with Apixaban

STEP 1 — Immediate Assessment & Stabilisation

1a. Haemodynamic check FIRST

Is the patient haemodynamically stable (no cardiac arrest, no obstructive shock, SBP >90 mmHg, no persistent hypotension)?
If unstable → systemic thrombolysis pathway (alteplase 10 mg IV bolus + 90 mg over 2 hours) — apixaban is NOT used acutely in haemodynamic instability
If stable → proceed to Step 2

1b. Immediate supportive care

Oxygen to maintain SpO2 94-98%
Analgesia for pleuritic chest pain (paracetamol ± opioid if needed)
IV fluids cautiously - <500 ml only (excess fluid worsens RV failure)
12-lead ECG + CXR

1c. Urgent bloods (do NOT delay anticoagulation for results)

FBC, U&Es (check actual serum creatinine), LFTs, PT, APTT
Troponin + NT-proBNP (risk stratification)
Group & Save

STEP 2 — Confirm Diagnosis & Risk Stratify

2a. Confirm PE

CTPA (gold standard)
If severe renal impairment were present (CrCl <30) or contrast allergy → V/Q SPECT; but eGFR 43 with weight 116 kg means actual CrCl is well above 30 ml/min — CTPA is appropriate

2b. Start interim anticoagulation if imaging is delayed

Do NOT wait for CTPA if high clinical probability (Wells >4)
Start Apixaban 10 mg BD immediately as interim anticoagulation

2c. Risk stratify with sPESI score (once PE confirmed)

Criterion	Score
Age >80 years	+1
Active cancer	+1
Chronic cardiopulmonary disease	+1
HR ≥110 bpm	+1
SBP ≤100 mmHg	+1
SpO2 <90%	+1

sPESI = 0 → low risk → consider outpatient discharge pathway (Step 3A)
sPESI ≥1 → higher risk → inpatient management (Step 3B)

STEP 3 — Anticoagulation with Apixaban (Dosing for This Patient)

Renal & weight check for dose decision:

Parameter	This patient	Threshold	Action
eGFR	43 ml/min/1.73m²	>15 = safe for apixaban	✅ Apixaban appropriate
Weight	116 kg	≤60 kg = dose-reduction criterion	❌ NOT met — no weight-based reduction
Age	(unknown - check)	≥80 = dose-reduction criterion	Check chart
Serum creatinine	Check actual value	≥133 µmol/L = criterion	Likely met at eGFR 43

Apixaban dose-reduction rule (need 2 of 3 criteria): Age ≥80 + weight ≤60 kg + creatinine ≥133 µmol/L

At 116 kg, the weight criterion is definitively not met, so the patient cannot score 2 of 3 regardless of age or creatinine. Standard VTE treatment dose applies.

Prescribe:

Apixaban 10 mg TWICE DAILY for 7 days (days 1-7)

then

Apixaban 5 mg TWICE DAILY (day 8 onwards, minimum 3 months)

No anti-Xa monitoring required for apixaban (unlike LMWH)
No bridging heparin needed — apixaban is a single-drug regimen
Take with or without food; twice daily dosing aids adherence

STEP 4 — Outpatient vs Inpatient Decision

4a. If sPESI = 0 → Outpatient pathway (per UHB + NICE NG158)

Confirm ALL exclusion criteria are absent:

Exclusion criterion	Check
HR >110 or SBP <100	Must be absent
Syncope/pre-syncope	Must be absent
SpO2 <94% or oxygen requirement	Must be absent
Active bleeding / high bleeding risk	Must be absent
RV dysfunction (ECG, troponin, NT-proBNP, echo)	Must be absent
CrCl <15 ml/min	✅ eGFR 43 → CrCl well above 15 — NOT excluded on renal grounds
Severe liver disease	Must be absent
On full-dose anticoagulation at time of PE	Must be absent
Other comorbidities needing admission	Must be absent
Social barriers (lives alone, no phone, frailty)	Must be absent

⚠ Key point: eGFR 43 (CKD stage 3b) does NOT by itself exclude outpatient management. The UHB threshold is CrCl <15 ml/min. This patient is well above it.

If eligible for outpatient:

Start Apixaban 10 mg BD now in ED/SDEC
If CTPA not yet done: discharge, return within 24 hours for CTPA via SDEC
Senior (Consultant/Registrar) review before discharge
Provide: written information leaflet, anticoagulation alert card, direct SDEC contact number, out-of-hours advice
Open access to SDEC for 2 weeks
1-week telephone/face-to-face follow-up

4b. If sPESI ≥1 → Admit for inpatient management

Continue Apixaban 10 mg BD
Monitor obs, oxygen requirement, repeat bloods at 24-48 hours
Echocardiogram only if RV dysfunction suspected or will alter management (not routine)
Consider early discharge once clinically stable and sPESI criteria met

STEP 5 — Ongoing Management & Discharge

5a. Duration of anticoagulation

PE type	Duration
Provoked (surgery, immobility, trauma)	3 months then stop
Unprovoked (no clear cause)	Minimum 3 months — extended therapy discussion at thrombosis clinic
Cancer-associated	Ongoing — see CAT guideline

5b. Renal monitoring on apixaban at eGFR 43

Recheck eGFR/U&Es at 1 month (particularly at this level of renal function)
If eGFR deteriorates to <15 ml/min → switch to UFH/LMWH with anti-Xa monitoring and haematology review
Annual renal function monitoring thereafter while on apixaban

5c. Discharge prescription

Supply 4 weeks of apixaban on discharge (10 mg BD for first 7 days, then 5 mg BD for remainder)
Apixaban is obtainable from primary care on FP10 prescription (unlike LMWH which must be hospital-supplied)

5d. Follow-up referral

Thrombosis/anticoagulation clinic referral via PICs before discharge (UHB: "Anticoagulant Team Discharge Referral UHB")
Include: anticoagulant type (apixaban), indication (PE), discharge dose, intended duration, concurrent medications
GP informed but should not be expected to organise follow-up independently

5e. 3-month review at thrombosis clinic

If persistent breathlessness or RV dysfunction at 3 months → consider CTEPH referral to post-PE respiratory clinic
If unprovoked PE → shared decision on extended anticoagulation (weighing recurrence risk vs bleeding risk)
If renal function has deteriorated → re-assess DOAC suitability

Summary Card

Step	Action
1	Haemodynamic assessment → stabilise → bloods + ECG + CXR
2	CTPA to confirm PE → sPESI risk score → interim apixaban 10 mg BD if delay
3	Apixaban 10 mg BD x 7 days then 5 mg BD — standard dose confirmed (116 kg fails weight criterion, cannot score 2/3 for reduction)
4	sPESI 0 + no exclusions → outpatient; sPESI ≥1 → admit. eGFR 43 alone does NOT bar outpatient management
5	Min 3 months treatment; thrombosis clinic referral; renal monitoring at 1 month; GP informed

can creatinine clearance be higher than egfr

Yes, and this is clinically important - especially for this patient.

Short answer: Yes, CG CrCl is frequently higher than eGFR (CKD-EPI), and the difference can be substantial in obese patients.

Why CG CrCl and eGFR differ

The two formulas measure different things:

	Cockcroft-Gault (CG CrCl)	CKD-EPI eGFR
Output	ml/min (absolute)	ml/min/1.73m² (normalised to BSA)
Weight used	Yes - actual body weight in numerator	No weight term
Purpose	Drug dosing	CKD staging, epidemiology
Used for DOACs	Yes (licensed trials used CG)	No

The key difference: BSA normalisation

CKD-EPI eGFR is indexed to a standard body surface area of 1.73 m² - the average surface area of a 70 kg adult. CG CrCl is not normalised - it uses actual body weight.

For an obese patient like this one (116 kg), whose BSA is likely ~2.3-2.5 m², the lab-reported eGFR (normalised) is artificially lowered relative to their actual kidney function. The CG CrCl will be meaningfully higher.

Worked example for this patient (eGFR 43, 116 kg)

Assuming a 60-year-old male with eGFR 43 (CKD-EPI):

Estimated serum creatinine at eGFR 43 ≈ 145 µmol/L (1.64 mg/dL)

Cockcroft-Gault:

CrCl = [(140 - age) × weight × 1.23] ÷ serum creatinine (µmol/L)

= [(140 - 60) × 116 × 1.23] ÷ 145

= 88 ml/min

If female (factor 1.04 instead of 1.23):

= [(140 - 60) × 116 × 1.04] ÷ 145

= 75 ml/min

Age/sex assumption	CG CrCl	CKD-EPI eGFR
60-year-old male	~88 ml/min	43 ml/min/1.73m²
60-year-old female	~75 ml/min	43 ml/min/1.73m²
70-year-old male	~75 ml/min	43 ml/min/1.73m²
70-year-old female	~63 ml/min	43 ml/min/1.73m²

In every scenario, the CG CrCl is significantly higher than the eGFR.

Why this matters clinically for this patient

1. DOAC dosing thresholds use CG CrCl, not eGFR

Drug	Contraindication threshold	Based on
Apixaban	CrCl <15 ml/min	CG
Rivaroxaban	CrCl <15 ml/min (treatment)	CG
Edoxaban	CrCl <15 ml/min	CG
Dabigatran	CrCl <30 ml/min	CG

This patient's eGFR is 43 - but their CG CrCl is likely 75-90 ml/min depending on age/sex. They are therefore comfortably within normal dosing range for all DOACs.

2. Outpatient PE exclusion threshold

The UHB guideline excludes outpatient management at CrCl <15 ml/min. At a CG CrCl of ~75-88 ml/min, this patient is not at all excluded on renal grounds.

3. LMWH accumulation risk

Meaningful LMWH accumulation occurs at CrCl <30 ml/min. This patient's CG CrCl is well above that, though anti-Xa monitoring is still advisable given weight >100 kg.

Important caveat in obesity: which weight to use in CG?

This is an active area of debate. The UK Kidney Association (Oct 2025) specifically flags this as an unresolved research question:

"In obesity, what weight should be used for the C-G CrCl when calculating appropriate dose of anticoagulants?"

In practice:

Actual body weight (ABW) - used in original CG formula, tends to overestimate CrCl in obesity
Ideal body weight (IBW) - may underestimate in obesity
Adjusted body weight (AdjBW = IBW + 0.4 × [ABW - IBW]) - often recommended for obese patients in pharmacy practice

For this patient (116 kg), using adjusted body weight would give a slightly lower but more realistic CrCl estimate - still likely 60-80 ml/min, well above any DOAC dosing threshold.

Bottom line

For this patient with eGFR 43 and weight 116 kg: the actual CG CrCl is approximately 75-88 ml/min - well into the normal functional range. The lab-reported eGFR of 43 makes the renal function appear worse than it is for drug dosing purposes because it is normalised to a 1.73m² body surface area, not this patient's actual larger body surface area. Apixaban at standard VTE treatment dose is appropriate and safe.

Patient details section

Height 160 cm (1.60 m), weight 116 kg, BMI 45.3 kg/m² (Class III obesity)
eGFR 43 ml/min/1.73m² (CKD Stage 3b) with estimated CG CrCl ~75-90 ml/min

Apixaban dosing table

Loading: 10 mg twice daily for 7 days
Maintenance: 5 mg twice daily (day 8 onwards, minimum 3 months)
Dose-reduction rationale clearly documented (weight 116 kg - weight criterion not met, cannot score 2/3)

Follow-up plan

1-week review, 1-month renal bloods, 2-week open SDEC access, 3-month thrombosis clinic
Renal monitoring trigger: if eGFR drops to <15 ml/min, switch anticoagulant

Thrombosis clinic referral section (PICs pathway, UHB format)

Safety-net / red flags box for patient

Sign-off checklist (anticoag alert card, patient leaflet, GP informed)

Footer citing UHB CG062 v5.0, NICE NG158, and UK Kidney Association guidelines

write this more professionally and tell me extra things to mention like with family? Weekend Oncall SHO : CT TAP chased: shows : . Some atelectatic changes seen at lung bases . There is a focal nodule of the left adrenal measuring 22 mm in diameter, with a density of 40 HU. . There is pulmonary embolus, with thrombus draped across the lobar division of the Right pulmonary artery Patient is Haemodynamically stable now: Obs stable, NEWS 1: Spo2 96% RA, RR 18, GCS 15/15, denies SOB/ chest Pain Patients Weight is 116kg, todays eGFR 43, (Creatinine Clearance 69 (Cockcroft-Gault Equation)) Patient currently on Prophylactic Enoxaparin 40mg OD Discussed with RMO2 BHH Dr Goyal in regards to initiating DOAC for confirmed PE Advised to commence on Apixaban 10mg BD for 1x Week then 5mg BD to continue Updated Husband and Patient in the ward Veronica feels generally well, no sob/ chest pain, hasnt opened bowels today in daytime She has been on bed more recently ( ↓ mobility) due to ongoing health issues, leg lymphedema, infection and diarrhea. Denies any calf pain or new swelling Updated both about CT findings of PE today, Explained the need to start on apixaban for PE Explained the risk of bleeding after starting on apixaban and that she needs to be extra careful not to have a fall. also need to monitor for any PR bleed / haematuria/ hamatemesis Both were thankful for the update and care given. Likely Provoked PE due to Immobility Plan: . Commence on Apixaban 10 mg BD x 7 days, then 5 mg BD to continue ( Stop prophylactic Enoxaparin) .

PE Clinical Note Veronica

Word Document · DOCX

Here is what was added and upgraded compared to the raw SHO note:

Extra clinical content added:

Left adrenal nodule - this needed flagging prominently. 40 HU on CT is above the 10 HU threshold for a lipid-rich adenoma, meaning it cannot be called a simple benign adenoma. The note now flags this as a separate urgent finding requiring dedicated adrenal CT washout or MRI adrenal, with Endocrinology/adrenal MDT referral. This is critical and must not get lost behind the PE management.

Bibasal atelectasis - documented with a note that no consolidation is seen, distinguishing it from pneumonia.

Family discussion section - documented formally, including: both Veronica and husband present, what was explained (PE diagnosis, adrenal nodule, apixaban need, bleeding risks, fall precautions, signs to return urgently), and their response.

Falls risk - formal falls risk assessment and physiotherapy review added given anticoagulation + morbid obesity + reduced mobility.

Bowels - flagged with a laxative plan and a specific note that PR bleeding must be reported urgently on anticoagulation.

Lymphoedema/infection management - added as an active item, not just background.

GP communication - specific content for the discharge letter including the adrenal nodule.

Checklist on sign-off - includes stopping enoxaparin, adrenal follow-up, anticoag alert card, and PICs referral.

Can AF Cause PE?

The relationship between AF and PE is real but indirect - and understanding the distinction matters clinically.

The Classical Teaching: AF causes ARTERIAL embolism, not venous

AF causes left atrial thrombus (particularly in the left atrial appendage) due to stasis of blood in a fibrillating, non-contracting atrium. When this thrombus breaks off it enters the systemic arterial circulation, causing:

Ischaemic stroke (most feared)
Peripheral arterial embolism (mesenteric, limb, renal)
Not PE - because left atrial thrombus goes forward into the aorta, not backward into the pulmonary arteries

This is why AF anticoagulation (e.g. apixaban 5 mg BD for AF) is dosed differently from VTE treatment, and the indication is stroke prevention, not PE prevention.

But AF IS associated with increased VTE / PE risk - here's why

Tintinalli's Emergency Medicine states directly:

"Atrial fibrillation increases the risk of venous and atrial thrombosis, with potential for pulmonary and systemic arterial embolism."

And the 2024 PE epidemiology review (Glazier & Baciewicz, PMID 38846994) lists hospitalisation for acute MI or heart failure with AF as a strong VTE risk factor.

The mechanisms are:

1. Virchow's Triad - Stasis AF causes global haemodynamic inefficiency - reduced cardiac output, venous congestion, and reduced venous flow velocity. This promotes stasis in the deep veins of the legs and pelvis - the source of 70-80% of all PE.

2. Hypercoagulable state AF itself is a prothrombotic condition. Patients with AF have elevated:

Fibrinogen
D-dimer
von Willebrand factor
Thrombin-antithrombin complexes

This systemic procoagulant state increases venous as well as arterial thrombosis risk.

3. Shared risk factors (confounding) AF and VTE share many predisposing conditions - heart failure, obesity, immobility, older age, malignancy, hypertension. Much of the observed AF-PE association is driven by these shared risk factors rather than AF causing PE directly.

4. Right heart failure / right atrial thrombus In AF with right heart failure or right atrial enlargement, thrombus can form in the right atrium or right atrial appendage. This thrombus CAN embolise directly into the pulmonary circulation and cause PE - this is a direct, though less common, mechanism. This is sometimes called paradoxical embolism when it passes through a patent foramen ovale (PFO).

5. Paradoxical embolism via PFO PFO is present in ~25% of the population. If AF causes raised right atrial pressure (e.g. due to RV dysfunction), it can force a venous thrombus through a PFO from right to left atrium, then into the systemic arterial circulation - paradoxically causing stroke rather than PE.

Summary table

Mechanism	Does AF cause it?	Clinical result
Left atrial thrombus	Yes - direct	Stroke / systemic arterial embolism
Right atrial thrombus	Yes - less common	PE (direct)
Venous stasis (low CO, immobility)	Yes - indirect	DVT → PE
Systemic prothrombotic state	Yes - indirect	DVT → PE
Paradoxical embolism via PFO	Rare	Stroke (not PE)
Shared risk factors	Confounding	Both AF and VTE more common

Clinical bottom line

AF does not directly cause PE via the usual left atrial thrombus mechanism - that goes the wrong direction. However AF is an independent risk factor for VTE/PE through haemodynamic stasis, systemic hypercoagulability, and occasionally right atrial thrombus. Large epidemiological studies consistently show a 1.5-2x increased VTE risk in AF patients.

This is clinically relevant: patients on anticoagulation for AF already have partial protection against PE as a side benefit - though the doses used for AF (e.g. apixaban 5 mg BD) are lower than acute VTE treatment doses (10 mg BD loading).
