Clinical Summary from the Notes

Should You Restart Aspirin and Atorvastatin?

Aspirin (Antiplatelet) - HOLD FOR NOW, Restart Urgently Once Bleeding Controlled

1. Discontinue DAPT (both aspirin + P2Y12) - already done per the cardiologist note
2. Aggressive resuscitation, transfuse PRBCs (1U already given - likely needs more given Hb 5.9 and shock)
3. Urgent endoscopy (EGD/colonoscopy) to confirm hemostasis
4. Restart aspirin on the day hemostasis is endoscopically confirmed - ACG guidelines specifically state aspirin should NOT be held indefinitely and should be resumed the day endoscopic hemostasis is confirmed
5. If DAPT is restarted, add high-dose PPI indefinitely
6. Thrombocytopenia (Plt 25k) is a separate, complicating factor - antiplatelets should not be restarted until haematology clears the platelet count (currently haematology referral is noted)

Atorvastatin - DO NOT STOP

• Continue atorvastatin at the dose already prescribed (typically 40-80mg for post-ACS/PCI)
• Note: AST/ALT are mildly elevated (137/49) - monitor LFTs, but this is likely from the hemodynamic shock/hypoperfusion, not statin hepatotoxicity. If LFTs worsen significantly (>3x ULN), reconsider, but do not stop empirically now.

Immediate Management Priorities

1. Resuscitate First (This is the Immediate Priority)

• IV access x2, aggressive IV fluids (cautious given cardiac history - use crystalloid boluses)
• More PRBCs - Hb 5.9 with hemodynamic shock: target Hb >8-9g/dL in this CAD patient; already received 1U, needs more
• Platelet transfusion - Plt 25k is critically low; threshold for transfusion in active bleeding is typically <50k; haematology referral already done - get platelets urgently
• Fresh Frozen Plasma (FFP) - APTT 24:2 is borderline; if coagulopathy worsens, consider
• Correct hypoxia - SpO2 92%, supplement oxygen (nasal cannula or mask), target SpO2 >95%

2. Identify the Bleeding Source

• P/R bleeding with constipation and straining - likely lower GI (haemorrhoids, anal fissure given straining) but cannot rule out upper GI source with melaena presentation
• Urgent colonoscopy / proctoscopy once haemodynamically stabilised
• If upper GI source suspected, urgent EGD
• Hb drop from what level is not documented - but Hb 5.9 with shock suggests significant blood loss

3. Address the Thrombocytopenia (Plt 25k)

• History of malaria (confirmed by the notes) - malaria-associated thrombocytopenia is very common and can be severe
• Drug-induced (check all medications)
• Disseminated intravascular coagulation (DIC) - check fibrinogen, D-dimer
• TTP/HUS (given AKI, elevated LFTs, thrombocytopenia - this triad warrants consideration)
• Haematology to sort this out urgently

4. Regarding the Angioplasty and Stent

• The cardiologist note mentions "go for stent tomorrow" - this likely refers to stenting an additional lesion (DVCAD = 2-vessel disease; only LCx was stented 1 month ago, second vessel may still need intervention)
• Any further procedure is contraindicated today given Hb 5.9, Plt 25k, and active bleeding/shock
• This elective/staged procedure must be deferred until the patient is stabilised, bleeding stopped, and platelets are correctable

5. ECG Changes

• RBBB pattern + negative axis + non-specific ST changes: monitor closely
• Rule out right heart strain (PE is in the differential given the thrombocytopenia and systemic illness), or demand ischemia from the acute anemia and hypotension
• Serial ECGs, troponin

6. Liver/Pancreas Findings

• Elevated amylase (184) and lipase (119) with elevated transaminases - could represent ischemic hepatitis/pancreatopathy from hypoperfusion (BP 66/40)
• Monitor trend; keep NBM if pancreatitis is significant

7. Renal Function (Cr 2.4)

• Likely pre-renal AKI from the shock state
• Aggressive fluid resuscitation, monitor urine output
• Avoid NSAIDs (contraindicated anyway)
• Adjust drug doses accordingly

8. Medications to Start/Continue

Summary in One Line

Important: This patient is critically unwell and the management decisions - particularly around restarting antiplatelets in a post-stent patient with active severe GI hemorrhage and severe thrombocytopenia - require urgent multidisciplinary input: cardiology, gastroenterology, haematology, and critical care. The notes already show this team approach is being initiated. Atorvastatin should never be stopped in a post-PCI patient during an acute event.

The Answer: Both - But in the Right Order and for the Right Reason

Step 1: IV Fluids First (but blood products are the priority)

"Patients with a shock state consistent with hypovolemia due to hemorrhage should undergo early blood and blood product resuscitation rather than crystalloid infusion, and early activation of a massive transfusion protocol instituted."

• Mulholland & Greenfield's Surgery, 7e

• 2 large-bore IV lines (14-16G)
• Fluid challenge: 500 mL NS over 15-20 min, then reassess BP
• NS is acceptable, but Ringer's Lactate is preferred if large volumes needed (NS risks hyperchloremic acidosis at high volumes)
• Simultaneously call for blood - this patient needs PRBCs urgently (Hb 5.9, already 1U given)

• Over-resuscitation with crystalloids alone in hemorrhagic shock increases risk of ARDS, ACS, and dilutional coagulopathy
• This patient already has Plt 25k - diluting further with saline will worsen coagulopathy
• Target: blood products (PRBCs + platelets + FFP in 1:1:1 ratio if massive transfusion needed)

Step 2: Noradrenaline - YES, but only if fluids fail

• BP does not respond to fluid challenge (BP remains <90 systolic or MAP <65 after 500-1000 mL)
• OR patient deteriorates rapidly and you need to buy time while blood is being arranged

"Currently, when crystalloid fluid resuscitation is not effective at raising blood pressure, norepinephrine is the vasopressor of choice"

• Sabiston Textbook of Surgery

Critical Caution: This Patient Has CAD with Recent PCI

• Give fluids in 250-500 mL boluses, reassess after each one
• Listen to lung bases before each bolus (watch for crackles)
• If SpO2 drops or new crackles appear after fluid - STOP fluids, give norad instead
• Keep a lower threshold for norad in this patient vs a young trauma patient

Practical Orders Right Now

1. IV NS 500 mL bolus over 20 min STAT → reassess BP
2. Repeat fluid challenge if BP responds but remains <90 systolic
3. PRBCs 2 units STAT (already 1 given - needs more)
4. Platelets from haematology URGENTLY (Plt 25k + active bleeding)
5. If BP still <90 systolic or MAP <65 after 1L fluid:
   → Start Inj Noradrenaline 0.1 mcg/kg/min IV infusion
   → Titrate up to maintain MAP ≥65
6. Target: MAP 65-70, HR <100, SpO2 >95%, UO >0.5 mL/kg/hr
7. Monitor: Lung bases for pulmonary oedema after each fluid bolus
