BP levels above which hypertension in child should be considered:

Common causes of hypertension according to age

Evaluation of asymptomatic hypertensive child:

Pediatric doses of anti hypertensive drugs:

Substances that can elevate BP

Why to treat HTN? –52%  in CHF –35-40%  in stroke morbidity and mortality –35%  in LVH –20-25%  CAD events –21%  vascular mortality

Benefits of Lowering BP Sustaining a 12 mmHg reduction in SBP over 10 years will prevent one death for every 11 patients treated with Stage I HTN w/additional CVD risk factors Sustaining a 12 mmHg reduction in SBP over 10 years will prevent one death for every 11 patients treated with Stage I HTN w/additional CVD risk factors

Treatment Outline Goals of Therapy Goals of Therapy Lifestyle modification Lifestyle modification Pharmacologic treatment Pharmacologic treatment Follow-up and monitoring Follow-up and monitoring

Goals of Therapy Reduce CVD and renal morbidity and mortality Reduce CVD and renal morbidity and mortality Treat to BP < 140/90 mmHg or BP <130/80 mmHg in patients with DM or less in patients with chronic KD Treat to BP < 140/90 mmHg or BP <130/80 mmHg in patients with DM or less in patients with chronic KD

Goals of Therapy Achieve BP goal especially in persons > 50 years of age Achieve BP goal especially in persons > 50 years of age Maintain QOL Maintain QOL Minimize side effects Minimize side effects

Lifestyle Modification Modification Approx. SBP reduction (mmHg) Weight reduction Adopt DASH diet Dietary Na+ restriction Physical activity Moderation of alcohol consumption 5 – 10 / 10 kg 8 – 14 2 – 8 4 – 9 2 – 4

Lifestyle Modification Works best in motivated individuals Works best in motivated individuals Initiate at prehypertension classification Initiate at prehypertension classification Obesity  risk for HTN and DM Obesity  risk for HTN and DM If > 20% over ideal body weight (IBW) – considered obese If > 20% over ideal body weight (IBW) – considered obese –Decrease intake by 500 cal/day –Increase exercise and activity

One KG decrease in BW is accompanied by reduction of 1.6 and 1.3 mmHg in systolic and diastolic BP.
