Jab Mein Thaa, Tab Guru Nahin‚
Aub Guru Hai, Mein Nahin
Sab Andhiyara Mit Gaya‚
Jab Deepak Dekhya Mahin
When "I“, the Ego, was with me, then I couldn’t
realize the almighty within; Now, the Almighty "is"
ever with me and there is no place for this Ego.
All the darkness (illusion) within me is mitigated,
on realizing the light (illumination) within.

Diabetic Hypertension
The Two Terrorists
THE ENORMITY OF THE
PROBLEM - COMPOUNDED
How Common is this Duo?
HTN is twice as common in DM
New onset DM is 2.5 times in HTN
20 to 40% of IGT pts have HTN
40 to 50% of Type 2 DM have HTN
Only 1/4 of HTN in DM is controlled
DM + HTN –  CV Risk 3 fold
What Causes HTN in DM
• Metabolic Syndrome – Mainly IR, ED,  BG
• Excessive RAAS activity is the main mechanism
• HTN due to nephropathy in T2DM – GS - KWL
• Renal scarring - Recurrent pyelonephritis
• Endocrine causes for both HTN & DM
– Cushing’s, Conn’s, Pheochromo, Acromegaly
• Coincidental – DM on existing HTN
• Diabetogenic antihypertensive drugs (D and B)
• Drugs causing both HTN & DM – OCP, CS
Each Perpetuates the Other

Difficulties of HTN in DM
• Systolic HTN more common in DM
• S-HTN is a stronger predictor of CVE
• 65% of T2DM have S-HTN
• S-HTN is more difficult to control
• Depression is more in DM – Adherence Rx
• ‘Clinician Inertia’ is a big problem
• Glycemic control only is the focus – No VP

•Inflammation

MRA – Eplerenone
ACEi or ARB – A must for VP
• Antihypertensive, vasoprotective,
anti-thrombotic and anti-inflammatory
• Inevitable in DM more so in DM + HT/CVD
• Reduce CV events, Reduce atherosclerosis
• Reduce renal disease - a strong CV risk factor
• Metabolically ‘friendly’ drugs in DM
• They prevent new onset DM, Nephropathy
• Well-tolerated with few side effects
ACE inhibitor or ARB
• Renal impairment – These improve
e-GFR, microalbuminuria or proteinuria
• LV dysfunction (along with new  blocker)
• Previous MI (along with new  blocker)
• Contraindicated in pregnancy
• Relative contraindications
- Bilateral renal artery stenosis
- Severe renal impairment (Cr > 3.0)
- Monitor renal function
- Angioedema, ACEi cough

1. Atorvastatin (Lipid management)
2. ASA (Acetyl Salicylic Acid) – (enteric

•
Must decrease blood pressure to  130/80
Must reduce the RAAS activity, improve ED
Must prevent, improve or arrest proteinuria
Must prevent and protect from CAD, CKD, CHF
Must be favourable on glycemic control
Must improve the dyslipidemia – not worsen it
Must not worsen peripheral arterial disease
Must improve ED and not cause impotence
Must not decrease eGFR and  serum creatinine
Must not raise uric acid, serum potassium
What should We take home ?
 ‘Clinician Inertia’ for HTN in DM must be overcome
 HTN in DM is serious; So manage aggressively
 TLC, Lipid control, Glycemic targets – VP is a must
 HTN Rx. delays or arrests CVD, CKD, PAD, CVD
 ACEi or ARBs are the main stay of Rx -  RAAS
 Postural hypotension, DAN are important in Rx
 MAU/ACR must for all DM – Predict CAD, CKD
 Typically 2 or more drugs are needed for HTN Rx.
 New
B, Carvedilol, CCBs are add-on drugs
