Very Alarming Indeed !!
• India is the Diabetic capital of the world
• Indians have one of highest rates of CAD
• Indian CAD is malignant in its onslaught
• Obesity in India is 3 fold compared to 1970
It is high time, all of us collectively do what
ever best is possible to prevent worsening !

Treatment Advances in CAD
• Thrombolysis – Rx. Algorithms• ICU care – Defibrillators, Ventilators, IABP• Coronary Angiogram, CT Angio, STS• Primary PTCA – Stents, Elective PTCA• Rescue Angioplasty – Drug Eluted Stents• CABG – Beating Heart Surgery• MRV, Angiogenesis - Stem Cell Research• Remember, all the above are prohibitively
expensive and not accessible to all
1.Benefit the lucky few patients who survived until the hospital door
2.They are at best palliative; not curative

CAD Scenario• Out 100 cases of MI
– 20 persons die – what ever we do or not ! - blessed ones !
– Of these – 14/20 (2/3) die even before they see us – lucky
– Pre hospital mortality – very sacred souls !!
– Remaining – 6/20 (1/3) – die in spite of us
– Some more may perish – because of us – iatrogenic causes
– 2 – 3% SCD – Sudden Cardiac deaths – exemplary !!!
– 1/3 cases of MI are silent MIs – ↑ Risk of death
– Among the 80 survivors – Reinfarction rates of > 30%
– Re-stenosis and failure of PTCA around 25%
– 10% of survivors – LVDF and CHF – chronic invalids
So, once we are a patient of MI, we are permanent patients +/- invalidity !!!

How to win the battle of CHD
• Coronary care units cannot answer all callers
• PTCA and CABG are not always feasible
• Are affordable by and available to only some
• Why make a valiant attempt to save the
myocardium after all the damage is done
• Why not protect our tiny blood pipes by
adopting preventive strategies at low cost !
Prevention is the only best weapon
Need to identify those at greater risk
Target them early to forestall damage

Prevention is the key
1. CVD - Is it preventable ?? - Very much Yes.
2. The risk assessment must start very early
3. At the age of 20 years itself
4. Healthy life style and hearty eating habits
5. Regular physical exercise from young age
6. Maintaining ideal weight and hour glass waist
7. Avoiding tobacco and reducing alcohol
8. There are enough guidelines – Implementation ?

CHD Risk Factors – So Many ?
• Malaria – One causative parasite• Tuberculosis – One definite bacterium • HIV and AIDS – One deadly virus• But for CHD – No one specific cause
– It is a non communicable disease
– It is multi factorial in its causation
– The more ignorant we are about the causation,
the more risk factors we seek and try to explain

Age and CAD
• CHD risk increases as age advances
• Men > 45 and women > 55 – high risk
• CAD-I is 10 years younger
• Men suffer CAD 10 years early
• Increased longevity – Aging population
• Increased duration of risk exposure
• Multiplicity of risk factors occurs
• Treatment responses are blunted

Gender and CAD
• CAD is ‘Disease of the Men’ – a myth
• Women CAD presents atypically
• Silent MI more common; 10 yrs later
• First attack mortality more common
• CAD deaths are twice those from all Ca
• DM is a more powerful risk factor for ♀
• ↑ TG, LDL and ↓ HDL are common in ♀
• Physical inactivity, Abd. obesity is more

The CADI Volcano• We are in the middle of the wave of CAD epidemic
• This CADI epidemic will peak by 2015
• 50% deaths in India are CVD deaths.
• CADI will overtake Infectious diseases in morbidity too
• By 2015 CADI will be six times more than the West
• CADI will be 20 times more than the Chinese, although
• Our culture shuns smoking, 50% are vegetarians and
• We lack many of the classic risk factors for CAD
• Remember CADI is preventable & predictable

Family Hx. of premature CAD
• H/o CAD in the first degree relatives
• CAD in male relative before the age 55
• CAD in female relative before the age 65
• Aggressive approach to Rx. of risk factors
• Look for non-conventional risk factors
• Lp(a), sLDL, ↓ HDL the main culprits

• There are 2 phenotypes of lipoproteins
• Phenotype A and Phenotype B
• Phenotype A is atheroprotective
• They have high HDL and low TG
• Atherogenic lipoprotein Phenotype B - ALP
• They have low HDL and high LDL, TG

Lp(a) or Little‘a’
• Similar to LDL molecule• Apo B + additional Apo ‘a’ attached by S=S bond• Primary determinant is genetic• Normal value 20 mg %, > 30 high risk• It competes with plasminogen because of its
structural similarity and so interferes with plasmin synthesis and thrombolytic pathway
• Nicotinic acid, Estrogens ↓it

Significance of Small, Dense LDL
• Low cholesterol content of LDL particles particle number for given LDL-C level
• Associated with levels of TG and LDL-C, and levels of HDL2
• Marker for common genetic trait associated with risk of coronary disease (LDL subclass pattern B)
• Possible mechanisms of atherogenicity– Greater arterial uptake uptake by macrophages oxidation susceptibility

• Control of all the known CV risk factors
• Main focus on the big six – DM, HTN, Lipids, Obesity, Smoking, Sedentary life style
• Diet and physical activity are vital in Rx of ED
• Statins are the first line treatment for ED
• Glitazones have proven value to improve ED
• Insulin and Rx. Insulin resistance improves ED
What is the Rx. for Endothelial Dysfunction?

ED = ED
• Erectile Dysfunction = Endothelial Dysfunction
• Marker of CV Health and CVD
• Due poor NO balance at the endothelium
• Penis is the barometer of cardiovascular health
• Close questioning is essential to uncover it
• Data suggests that is more so in South Asians

Micro Albuminuria (MAU)
• MAU: 30-300mg albumin in urine over 24 hrs
• Occurs in DM and HT
• Detected by new dipstick tests for MAU
• Most accurate assessment is 24hr collection
• Screening by ACR on spot urine (first morning)
• MAU is a marker of early stage renal damage
• Regression of MAU decreases risk
• A marker of generalized CVD risk

• HT is a strong risk factor for CHD and CVD
• ISH is more important than ↑ DBP alone
• Salt restriction – daily 2 g/day of Na
• Diet low in saturated fats. Rx. Of dyslipidemia
• Goal B.P. is 140/90 – 10 mm less for Diabetic HT
• ACEIs / ARBs, BB, Thiazides - at least 2 drugs
• ISH – CCBs and BBs; Indapamide useful
• TOD – LVH, ABI, Pulse pressure, Brachial FMD

Gould AL et al. Circulation. 1998;97:946-952.
Clinical Benefits of Cholesterol Reduction
• A recent meta-analysis of 38 trials demons- trated that for every 10% reduction in TC
•CHD mortality decreased by 15% (P<0.001)•Total mortality decreased by 11% (P<0.001)
• Decreases were similar for all treatment modalities
• Cholesterol reduction did not increase non-CHD mortality

At what cost one suffers !!
1. Rs 50 x 30 days = 1500 x 12 months = 18,000/yr
2. Age 45 to 65 – 20 years x 18,000 = 3,60,000
3. Cost of CABG or PTCA + Stent = 2,00,000
4. What about the cost of his consultations, tests etc.
5. What about his co-morbidities like OA, Cataract
6. What about his inter current illnesses and admiss.
7. What about treatment for CHF, RF, PVD, Laser
8. No third party payer – has to spend by himself !!
9. What is value of all this prolonged suffering ? ?

Think for a moment ….• Should we not address this early from 20s or 30s ?• Should we wait till we all suffer and succumb ?• Is it not cost-effective and safe to take action now ?• What for are we waiting? Whose permission is needed?• Who will bell the cat to motivate for CAD prevention• It will never be a priority for our rulers ! • It is we – the answerable ones for all – should take steps • Take a pledge now to screen all above 30 years• Initiate them into preventive action – persuade – persist
