SUMMARY...

F.H:mother and brother having heart disease,HTN, and obesity

.

Follow-up :

Due to his age and F.hx& examination( include obesity, stage I hypertension, and metabolic syndrome.)

SHOULD consider DM2 and atherosclerotic CVD

the primary purpose is to establish treatment goals for associated risk factors such as:

HTN,HLP&hyperinsulinemia all of which result in increased CVA&CVD and

mortality

Case present...

Teaching Plan:

A F/U visit for TLC:

Weight reductioneating plan, including fruits, vegetables, low-fat

dairy, whole grains, fish, and nuts; and minimal amounts of fats, red meat, sweets...

Reduction in dietary sodium intake

Increased physical activity

Stop smoking

Case presentation:

Pharmacologic Considerations:

low-dose ACE I: to control HTN stageI

atorvastatin (Lipitor): to reduce his LDL-C & TG levels

Fibrates : effective in lowering TG

(Combination therapy with a fibrate and a statin useful for patients with atherogenic lipid profiles)

Metformin(optional)
