Study Notes
Antibiotic Prophylaxis Recommendations
- Antibiotic prophylaxis (AB prophylaxis) is recommended for patients with a history of previous infective endocarditis (IE), prosthetic cardiac valves, congenital heart disease (CHD), or cardiac transplantation.
- Standard AB prophylaxis regimen includes:
- 2g Amoxicillin administered 30-60 minutes prior to the procedure.
- 500mg Azithromycin also administered 30-60 minutes prior, or alternatively, 2g Cephalexin can be used.
- Antibiotics can be given up to 2 hours post-procedure if necessary.
- For cardiovascular (CV) devices, AB prophylaxis is advised if:
- Dental procedures involve incision and drainage.
- There is a residual leak after CHD repair or closure.
- AB prophylaxis is not recommended for patients with prosthetic joint implants.
Cardiovascular and Myocardial Infarction Insights
- Patients with a history of myocardial infarction (MI) greater than 6 months prior have the lowest risk for recurrent MI.
- Delaying dental treatment can increase risk due to:
- Endogenous catecholamine release leading to elevated heart rate and blood pressure.
- Increased myocardial oxygen demand during stress.
- Necessity for effective post-operative pain control.
- Importance of revascularization and reperfusion therapies in MI recovery.
- Current guidelines indicate that:
- Elective dental treatments or surgeries are contraindicated within 4-6 weeks post uncomplicated MI.
- Elective dental treatments or surgeries are contraindicated within 60 days if no coronary intervention has occurred.
- A threshold of METs (Metabolic Equivalent of Task) 4 or greater is used to assess cardiac stability during procedures.
- Factors considered when determining major adverse cardiac events (MACE) include:
- Patient-specific factors.
- Recent history of myocardial infarction.
