What is post-PCI (percutaneous coronary intervention) management?

Post-PCI Management

Post-PCI management should focus on monitoring for recurrent ischemia, achieving hemostasis at the catheter site, preventing contrast-induced renal failure, and implementing secondary prevention programs to reduce morbidity and mortality. 1

Immediate Post-PCI Care

• In-hospital care should focus on monitoring for recurrent myocardial ischemia, achieving hemostasis at the catheter insertion site, detecting and preventing contrast-induced renal failure, and monitoring vascular closure device results 1
• Most patients can be safely discharged from the hospital within the next calendar day after an uncomplicated elective PCI 1
• Monitor post-PCI hematocrit for a decrease greater than absolute 5-6% to detect potential bleeding complications 1
• Be alert for retroperitoneal hematoma, which may present with hypotension, suprainguinal tenderness, and severe back or lower-quadrant abdominal pain 1

Antiplatelet Therapy

For Patients Without Indication for Oral Anticoagulation:

• For all post-PCI stented patients, dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor is recommended 1
• For bare metal stents (BMS):
  • Clopidogrel 75 mg daily for at least 1 month (minimum 2 weeks if increased bleeding risk) 1
  • Ideally continue DAPT up to 12 months if not at high bleeding risk 1
• For drug-eluting stents (DES):
  • Clopidogrel 75 mg daily for at least 12 months in non-ACS patients 1
  • For ACS patients, P2Y12 inhibitor (clopidogrel, prasugrel, or ticagrelor) for at least 12 months 1
• After DAPT completion, continue aspirin 75-162 mg daily indefinitely 1
• In patients with high bleeding risk, shorter DAPT duration (1-3 months) may be considered 1

For Patients With Indication for Oral Anticoagulation:

• After uncomplicated PCI, early cessation (≤1 week) of aspirin and continuation of dual therapy with oral anticoagulant (OAC) and clopidogrel should be considered 1
• Triple therapy (aspirin, clopidogrel, OAC) for ≥1 month should be considered when stent thrombosis risk outweighs bleeding risk 1

Secondary Prevention Measures

Lipid Management:

• Start statin therapy in all patients, with high-intensity statins recommended to achieve LDL-C goals 1
• Target LDL-C less than 70 mg/dL in very high-risk patients 1
• Consider omega-3 fatty acids as adjunct for high triglycerides 1

Blood Pressure Control:

• Target blood pressure <140/90 mmHg (or <130/80 mmHg for patients with chronic kidney disease or diabetes) 1
• Consider ACE inhibitors for all CHD patients indefinitely; start early after MI in stable high-risk patients 1
• Use angiotensin receptor blockers in post-STEMI patients intolerant of ACE inhibitors who have heart failure signs or LVEF <0.40 1

Diabetes Management:

• Target HbA1c less than 7% 1
• Coordinate diabetes management with the patient's primary care physician and/or endocrinologist 1

Lifestyle Modifications:

• Promote complete smoking cessation 1
• Encourage minimum of 30-60 minutes of physical activity, preferably daily or at least 5 times weekly 1
• Recommend cardiac rehabilitation programs, particularly for moderate to high-risk patients 1
• Target BMI range of 18.5-24.9 kg/m² 1

Follow-up Testing

• Treadmill exercise testing is reasonable for patients entering formal cardiac rehabilitation programs 1
• Routine periodic stress testing of asymptomatic patients without specific clinical indications should not be performed 1
• Routine follow-up invasive coronary angiography is not recommended 1

Common Pitfalls and Caveats

• Premature discontinuation of DAPT is associated with increased risk of stent thrombosis - patients should be counseled on the importance of compliance 1, 2
• Noncardiac surgery should be delayed until 12 months after coronary stenting if possible 2
• Vascular complications may occur in patients after PCI, especially with aggressive anticoagulation, requiring vigilant monitoring 1
• Routine platelet function or genetic testing is currently not recommended to tailor antiplatelet therapy after PCI 2
• When using low-molecular-weight heparins, ACT should not be used as a guide to anticoagulation therapy 1

By following these evidence-based recommendations for post-PCI management, clinicians can optimize outcomes and reduce morbidity and mortality in patients undergoing percutaneous coronary intervention.
