HYPERTENSION AND OXIDATIVE STRESS
  • Oxidative stress with an imbalance between ROS
    and the antioxidant defense mechanisms may
    contribute to the etiology of hypertension, its
    initiation, maintenance, pathogenesis,
    pathophysiology, and cardiovascular complications

17
HYPERTENSION AND OXIDATIVE STRESS
  • Essential hypertension and salt sensitive HT
  • Diabetes and hypertension
  • Lead induced hypertension
  • Uremic hypertension
  • Cyclosporin induced hypertension
  • Pre-eclampsia
  • Nutritional induced (high fat and unrefined
    carbohydrates) hypertension

18
HYPERTENSION AND OXIDATIVE STRESS ROS IN
HYPERTENSION
  • ROS has direct action on endothelial cells with
    structural and functional damage
  • Degradation of NO by ROS
  • Effects of eicosanoid metabolism in endothelial
    cell
  • Oxidative modification of LDL-c (oxLDL)
  • Hyperglycemia, hyperinsulinaemia
  • Increased fatty acid mobilization
  • Increased catecholamines
  • Angiotensin II increases O2- via NADPH oxidase

19
IMPAIRED DEFENSE TO ROS
  • Increased lipofuscin, increased lipid
    peroxidation
  • Increased malondialdehyde, increased lipid
    peroxidation
  • SOD decreased in erythrocytes and plasma
  • Glutathione peroxidase decreased
  • Decreased vit A
  • Decreased Vit c

20
IMPAIRED DEFENSE TO ROS CONTINUED
  • Decreased vit e
  • Decreased NO
  • Increased O2- by PMN and increased H2O2
  • Decreased PUFA in RBC membrane
  • Decreased glutathione
  • Decreased selenium

21
Lifestyle changes and SBP metanalysis of clinical
diet trials
  • Intervention reduction in SBP (mmhg)
  • ---------------- ----------------------
    ---------
  • Mg 0-1
  • Ca 2
  • K 4
  • Decreasing ETOH 4
  • Fish oil 6
  • Lowering Na 6
  • Lowering weight 8
  • Exercise 10

22
Lifestyle modifications and withdrawal of
antihypertensive drugs, J Hypertension
19886431-6
  • Between 15 and 60 of hypertensive patients
    withdrawn from antihypertensive drugs remain
    normotensive for 9 to 36 months on strict
    lifestyle modifcations of nutrition, weight loss,
    exercise, alcohol and sodium restriction,etc

23
PROTEIN, Current atherosclerosis reports
20002521-528 Jama 19962741598-1603
  • Observational epidemiologic studies indicate a
    high protein intake reduces BP (non-animalgtvs
    animal protein) in numerous populations
  • Daily intake recommended1-1.5g/kg/day depending
    on many factors
  • Intermap study inverse relationship of BP with
    total protein intake and non-animal protein

24
Protein (continued)
  • Intersalt study 10020 subjects, worldwide had
    lower blood pressure (3/2.5mm hg) with dietary
    protein gt30 above mean vs those 30 below mean
    (81g vs 44g/day)
  • Mechanisms ACEI, reduces SNS (Epeinephrine/NE,
    natriuresis, inhibits tyrosine kinase, reduces
    aldosterone, reduces superoxide ion

25
SOY PROTEIN , Biochem Pharmacol 2000601-5
  • Lowers BP and increases arterial compliance
  • Lowers LDL-c (7), TC (6), LDL oxidation
  • Consume 25g/day
  • Contains isoflavones, amino acids, saponins,
    phytic acid, trypsin inhibitors, fiber,
    globulins, genistein/daidzen

26
Whey protein, J dairy Sci 200083255-263
  • Significant reduction in BP in animal and human
    studies
  • 30-150mg/kg of ion exchange hydrolyzed whey
    protein isolate reduces MAP 10-18 for 24 hours
    (plt0.05)
  • Must be hydrolyzed to be effective
  • Act as ACEI

    decreased SBP significantly (plt0.05)

27
Omega 3 PUFA circ 199288523-33
Hypertension 199832710-717
  • Meta-analysis 31 studies fishoil and BP showed
    dose related effect in mild hypertension only
  • lt 4g/d no change in BP
  • 4-7g/d lowered BP by 1.6-2.9mm hg
  • gt15g/day lowered BP by 5.8-8.1mm hg
  • One percent increase in adipose tissue
    alpha-linoleic acid content reduced SBP, DBP and
    MAP by 5mm hg

28
OMEGA 3 PUFA, current atherosclerosis reports
20002508-515 Hypertension 199934253-60
  • Fish 3 x/week lowers BP (herring, haddock,
    atlantic salmon, trout)
  • Fish or fishoil weight loss is additive to
    lower BP
  • DHA better to lower BP
  • Reduced ALA conversion to EPA and DHA (increased
    linoleic acid in diet omega 6, increased TSFA and
    TFA in the diet, alcohol)

29

    decreases adrenal AT1 receptor density /
    affinity)
  • Neurohormonal regulation (SNS, RAAS)-central
    peripheral

30
MUFA (olive oil), arch IM 2000160 837-842
  • 23 hypertensive subjects studied for 6 months.

    virgin olive oil group, plt0.05 and gt0.01
  • Reduces need for antihypertensive drugs in 48 vs
    4 in control group
  • Reduces BP in type II DM
  • No reduction of BP in normotensive, or
    non-diabetics

31
MUFA (olive oil) continued
  • Rich in oleic acid (w-9)
  • Extra virgin5mg phenols/10 g oil
  • 40g4 tablespoons full
  • Increases HDL
  • LDL-c rich oleate more resistant to ox LDL

    significantly increases BP

32
Garlic, Heart disease 200023-9phytochemistry
1992312389-2391
  • Consisten dose dependant BP reduction
  • Cultivated garlic allium sativum (not all
    garlic preparations are processed similarly and
    not comparable in antihypertensive effect)
  • Wild uncultivated garlic allium urisinum

33
Garlic mechanisms of action
  • Garlic is a natural ace inhibitor and CCB
  • ACEi due to flvanolic compounds

  • Increases NO
  • Decreases sensitivity to NE
  • Increases adenosine

    colloid

35
Pyridoxine, vit b6 Mol cell Biochem
1998188137-148

    excretion, as does glutathione
  • Decreases BP
  • Blocks calcium influx, improves insulin
    sensitivity
  • Reduces central sympathetic nervous system
    activity

    glucocorticoids, mineralocorticoids

36
LYCOPENE, paran study

37
Coenzyme q10, ubiquinone, Alternative Med Review
1996 (1),(3)171-174
  • High correlation of coq10 deficiency and
    hypertension
  • Coq10 reduces with age, disease, oxidative
    stress,statins, CHD, HT, Hyperlipidaemia, DM,
    aerobic exercise, atherosclerosis,
    hyperthyroidism
  • Dose 100-225mg/dBP reduction occurs at 4-12
    weeks after initiation

38
Coq10 continued
  • Reduces total dose and frequency of
    administration of antihypertensive drugs
  • Lowest serum pretreatment levels of coq10 have
    best reduction in BP
  • Average BP reduction in all trials is 15/10mm hg
  • Improves lipids, CHO metabolism, insulin
    sensitivity, decreases HR, decreases ROS,
    improves LV function, ischemia, angina, CHD, CHF,
    lowers NE levels

39
VITAMIN C
  • SBP is reduced proportionately more than DBP, but
    both are decreased
  • Epidemiological, observational, cross sectional
    and controlled studies confirm improvement of
    both SBP, DBP and HR
  • Lipid profile seems to be beneficial with small
    reductions in TC, TG, and LDL and oxLDL, and a
    slight increase in HDL in women
  • Dose 200-1000mg/d
  • Combinations with other antioxidants such as vit
    e, beta carotene or selenium provide synergistic
    anti-hypertensive effects

40
N-Acetyl cysteine (NAC), J Am cell nutr
19865137-151
  • SHR study normalizes BP by binding to excess
    aldehydes, reducing cytosolic ca and bp

    chronic oral administration in normotensives,
    hypertensives, salt sensitive hypertensives, DM
    and hyperlipidemics
  • In CHD it increases coronary artery bloodflow and
    decreases angina
  • In peripheral arterial disease, blood flow is
    increased and claudication decreased

42
Taurine
  • Clinical use HT, hyperlipidaemia, arrhythmias,
    CHD, CHF
  • Lowers BP, decreases proteinuria, decreases LVH,
    decreases SNS activity centrally
