Risk Factors
 Traditional

- ↓HDL, obesity, DM,
- age >45♂, >55♀,

small dense LDL, visceral obesity , fasting hyperinsulinemia,
microalbuminuria.
NB; Effect of smoking;
- ↑ Bl viscosity, ↑ carboxyHb, & Hct.

resistance.
 People at risk are;
1. Acquired valvular HD with stenosis or regurge.
2. Valve replacement.
3. structural congenital HD except isolated ASD, fully repaired VSD
or PDA, closure devices that are judged to be endothelialised.
4. HCM

Advice people at risk about;
- Good oral hygiene.
- Symptoms of IEC.
- Risks of invasive procedures
- Why ab prophylaxis is no longer indicated.
• Do not offer ab prophylaxis for;
- All dental procedure. except….
- Upper & lower GIT, respiratory, genitourinary.
- Do not offer chlorhexidine mouth wash before dental
procedures.

- Offer ab that cover organisms causing IEC for those pts
undergoing procedures at a site where there is a suspected
infection.

with 2 or more antihypertensive drugs to achieve goal BP
After 1 month if target BP is not reached: reach optimum
doses or add additional drug
Inadequate response to antihypertensive drugs
