hypertension Flashcards
SECONDARY HYPERTENSION
causes
and pervalence of primary hypertension
SECONDARY HYPERTENSION (6-8%)
KIDNEY DISORDERS
- Parenchymal disease
- Renovascular hypertension
ENDOCRINE DISORDERS
- Cushing’s Syndrome
- Primary hyperaldosteronism
- Congenital hypertrophy of the adrenal cortex
- Pheochromocytoma
- Hyperthyroidism
- Acromegaly
Iatrogenic causes
- Oral contraceptives or estrogen therapy
- Glucocorticoids, mineralocorticoid, sympathomimetic
- Lead poisoning
primary HYPERTENSION (92-94%)
Diseases that correlate with hypertension
- Insufficiency heart
- Coronary artery disease
- Blindness
- Preeclampsia / eclampsia
- Gangrene of lower extremities
- Break aneurysm aortic
- Chronic renal inssuficiency
- Hemorrhage cerebral
- Stroke
- hypertensive Encephalopathy
Complications of hypertension, of different natures
of pressure nature
• Accelerated-malignant hypertension
• Encephalopathy
• Cerebral hemorrhage
• Aortic dissection
• Heart failure
• Renal failure
of atherosclerotic nature
• Cerebral thrombosis
• Myocardial infarction
• Angina pectoris
• arteriopathy of the lower limbs

Clinical evaluation of hypertension
CLINICAL EVALUATION
1. Clinical History
(family history, medical history and the next)
2. Physical Examination
(CNS, heart, abdomen, peripheral vessels)
3. Laboratory Tests
(biochemistry, blood count)
4. Instrumental Tests
(ECG, RxTorace, echocardiography
Arterial hypertension. Laboratory investigations. Tests recommended for all hypertensive patients.
TEST RECOMMENDED FOR ALL THE HYPERTENSIVE
• Hemoglobin and hematocrit
• Creatinine plasma
• plasma uric acid
• serum sodium and potassium
• Glucose
• Trim fat (triglycerides, cholesterol and HDL)
• Analysis of urine (urinary sediment)
• Electrocardiogram
• Microalbuminuria
Additional tests for arterial hypertension patients
ADDITIONAL TEST
• Fundus oculi
• Chest Ro
• Echocardiogram
• Ultrasound renal
• Measurement of the PA in the 24 hours (ABPM)
Factors influencing the choice of antihipertensive drugs
- The risk profile of the patient’s CV
- The presence of concomitant diseases that
promote or restrict the use of a class
therapeutics - Different individual response to different
classes of drugs - The risk of drug interactions
- Clinical evidence
- Other
Major risk factors. of hypertension
Major risk factors
• SMOKE
• DysLIPIDEmIA
• DIABETES
• Chronic renal injury
• old age (> 60 years)
• SEX (Men and Women in menopause)
• HISTORY POSITIVE FOR CARDIOVASCULAR DISEASE EARLY
Or when these organs are damaged:
• HEART
• STROKE
• NEPHROPATHY
• peripheral arterial disease
• RETINOPATHY
Site of action of the main antihipertensive drugs.

beta - Blockers
Calcium - Antagonists *
Diuretics
peripheral resistance
ACE Inibitori
AT1 Bloccanti
alfa- Bloccanti

ELDERLY PATIENT
There is clear evidence of the effectiveness of
therapy in reducing mortality / morbidity CV
Hypertension and Renal Disease:
Implications for Treatment
Hypertension and proteinuria are independent variables predicting reduction of renal function in the long term
- Chronic renal injury is both a cause and consequence of hypertension
- The reduction of BP and proteinuria decreases renal and probably cardiovascular risk
Drugs used for hipertension treatment
primary choice
Hydrochlorothiazide / chlorthalidone
Furosemide/Torasemide
then
Aggiungere beta- bloccanti and/or alfa-beta bloccanti
Ca-antagonista
or
**(alfa-blocators, antiadrenergici centrali) **
Secondary hypertension
causes 3
- renovascular hypertension
(Stenosis, occlusion) - primary aldosteronism
(adenoma, hyperplasia
bilateral) - pheochromocytoma
Renovascular hypertension diagnosis. Clinic, laboratory
Renovascular hypertension: diagnosis
- CLINIC
- Age of onset <35 or> 60 years
- Sudden onset
- Poor control drug
- Presence of signs of diffuse atherosclerosis
- Breath paraumbilical - LABORATORY
- increased creatinine
- Hypokalemia
- Increased PRA
