16HYPERTENSION 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
17HYPERTENSION 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
18HYPERTENSION 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
19IMPAIRED 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
20IMPAIRED 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
21Lifestyle 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
22Lifestyle 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withdrawn from antihypertensive drugs remain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
23PROTEIN, 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
24Protein (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
25SOY PROTEIN , Biochem Pharmacol 2000601-5
- Lowers BP and increases arterial compliance
- Lowers LDL-c (7), TC (6), LDL oxidation
- Consume 25g/day

phytic acid, trypsin inhibitors, fiber,
globulins, genistein/daidzen
26Whey 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
- 20 men given 200ml whey protein BID x 8 weeks
decreased SBP significantly (plt0.05)
27Omega 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
28OMEGA 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)
29OMEGA 6 FATTY ACIDS
- LA, GLA, DGLA,AA, CLA
- GLA -gtDGLA -gt PGE1 and PGI2 cause vasodilation
- GLA blocks stress induced hypertension
- (increases PGE1, PGI2, decreases aldosterone,
decreases adrenal AT1 receptor density /
affinity) - Neurohormonal regulation (SNS, RAAS)-central
peripheral
30MUFA (olive oil), arch IM 2000160 837-842
- 23 hypertensive subjects studied for 6 months.
- Significant reduction in BP 8/6mm hg in extra
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
31MUFA (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
- Polyphenols antiooxidants
- Replacing dietary olive oil with saturated fat
significantly increases BP
32Garlic, 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
33Garlic mechanisms of action
- Garlic is a natural ace inhibitor and CCB
- ACEi due to flvanolic compounds
- Natural CCB / vasodilator (MG)
- Increases NO
- Decreases sensitivity to NE
- Increases adenosine
- Vasodilation
- Inhibits AA metabolites (TxA2)
- Reduces aortic stiffness (improves aortic
compliance) - Decreases ROS
34Seaweed, J Nutr biochem 200011430-4
- Wakame (undaria pinnatifida)
- Most popular edible seaweed in Japan
- Ace inhibition similar to captopril
- Lowers SBP 14-3 mmhg, DBP 5-2mm hg
- Ion exchange sodium absorbing/potassium releasing
seaweed preparation - Mechanisms ACEi, 771 minerals, fiber, alginate
colloid
35Pyridoxine, vit b6 Mol cell Biochem
1998188137-148
- B6 increases cysteine synthesis from methionine
- Cysteine is precursor of glutathione
(antioxidant) - Cyteine nuralizes aldehydes and increases
excretion, as does glutathione - Decreases BP
- Blocks calcium influx, improves insulin
sensitivity - Reduces central sympathetic nervous system
activity - Decreases end organ responsiveness to
glucocorticoids, mineralocorticoids
36LYCOPENE, paran study
- 30 subjects with HT, age 40-65
- SBP fell 9mm hg (plt0.01)
- DBP fell 7mm hg (plt0.01)
- Improvement in lipid profile
37Coenzyme 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
38Coq10 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
39VITAMIN 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
40N-Acetyl cysteine (NAC), J Am cell nutr
19865137-151
- SHR study normalizes BP by binding to excess
aldehydes, reducing cytosolic ca and bp - Thiol containing antioxidant, scavenges ROS
- Supports glutathione synthesis intracellularly
- Increases NO
- Calcium channel blocker activity
- Lowers homocysteine,lp(a) and platelet
aggregation - Improves ED in smokers (600mg)
41L-arginine, J clin invest 1991881559-67
- Reduces bp in humans with acute parenteral and
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
42Taurine
- Clinical use HT, hyperlipidaemia, arrhythmias,
CHD, CHF - Lowers BP, decreases proteinuria, decreases LVH,
decreases SNS activity centrally - Human study fujita (19 hypertensive subjects,
6g taurine x 7 days, lowers BP 9/4.1mm hg(plt0.05) - Mechanisms diuresis, decreases homocysteine,
increases insulin sensitivity, aldosterone - Dose 2-3g
