HYPERTENSION by Mind Map: HYPERTENSION

1. Definition

1.1. An elevated blood pressure (BP) is defined as a systolic blood pressure (SBP) > 140 mm Hg or diastolic blood pressure (DBP) > 90 mm Hg or both.

2. Classification

2.1. • Normal

2.2. • Prehypertension

2.3. • stage 1 hypertension

2.4. • stage 2 hypertension

3. Type

3.1. 1. Primary (essential or idiopathic) hypertension

3.2. 2. Secondary Hypertension

4. Hypertension in Elderly

4.1. • Isolated systolic hypertension (ISH)

4.2. • Lifetime risk of developing hypertension

4.3. • Reasons for increased BP in elderly

5. Mechanism

5.1. Neurogenic control

5.2. Renin-angiotensin system

6. Sign & symptoms

6.1. 1. Primary Hypertension

6.1.1. does not have symptoms other than high blood pressure

6.2. 2. Secondary Hypertension

6.2.1. • Most likely caused by Renal Disorders, symptoms you will see: • Decreased urine formation • Increased sodium and water retention

7. Complications

7.1. • Peripheral vascular disease • Nephrosclerosis • Retinal damage

8. Treatments

8.1. Non-pharmacological treatment

8.2. Pharmacological treatment

9. Rehabitation

9.1. Nutrition and Dietary Supplements

9.2. Exercise Training

10. Causes of hypertension in elderly

10.1. 1. Increased collagen and stiffness of myocardium

10.2. 2. Loss of baroreflex

10.3. 3. Loss of beta I-adrenergic receptors stimulation

10.4. 4. Changing of endothelial cells

10.5. 5. Inefficient renal system

10.6. 6. May have altered drug absorption; delayed metabolism and excretion; becareful when medicating.
