Overview
Multi-vessel coronary artery disease (MVD) involves significant narrowing of multiple coronary arteries, increasing the risk of myocardial infarction and reducing quality of life 1.Diagnosis
Clinical Presentation: Typical angina, atypical chest pain, dyspnea, and signs of heart failure 1.
Diagnostic Tests:
- Coronary Angiography: Gold standard for visualizing coronary artery stenosis 1.
- Non-invasive Imaging: Stress echocardiography, myocardial perfusion imaging to assess ischemia 1.
Grading: Utilize the SYNTAX score to quantify complexity and guide revascularization strategy 1.Management
Revascularization:
- Percutaneous Coronary Intervention (PCI): Preferred for lesions amenable to stenting, often with drug-eluting stents 1.
- Coronary Artery Bypass Grafting (CABG): Indicated for left main disease, complex three-vessel disease, or significant proximal LAD stenosis 1.
Pharmacotherapy:
- Antiplatelet Therapy: Dual antiplatelet therapy (e.g., aspirin + P2Y12 inhibitor) post-PCI 1.
- Statins: High-intensity statin therapy to reduce LDL cholesterol 1.
- Beta-Blockers: To reduce myocardial oxygen demand and improve survival 1.
- ACE Inhibitors/ARBs: For patients with left ventricular dysfunction or hypertension 1.
- Diuretics, Aldosterone Antagonists: As needed for heart failure management 1.Special Populations
Pregnancy: Limited specific guidance in provided abstracts; individualized risk assessment and conservative management preferred 1.
Pediatrics: Not addressed in provided abstracts 1.
Elderly: Tailored revascularization strategies considering comorbidities and functional status; CABG may be preferred in complex cases 1.
Comorbidities: Management adjusted based on coexisting conditions like diabetes, hypertension, and renal impairment; multidisciplinary care recommended 1.Key Recommendations
Utilize coronary angiography for definitive diagnosis and revascularization planning (Evidence: Strong 1).
Select revascularization strategy (PCI vs. CABG) based on lesion characteristics and patient factors, guided by scores like SYNTAX (Evidence: Moderate 1).
Implement high-intensity statin therapy and dual antiplatelet therapy post-revascularization to reduce cardiovascular events (Evidence: Strong 1).References
