The risk of diabetes associated with antihypertensive-drug therapy appears to be explained by the presence of hypertension.

Among the subjects who had hypertension, the risk among those not taking medication was similar to that among those taking one or more agents.

Among the subjects who were not taking any antihypertensive medication, the risk of diabetes was much higher among hypertensive Pts. than in non hypertensive.

DiabetesDiabetes HypertensionHypertension

Hypertensive patients without diabetes tend to be resistant to insulin and are hyperinsulinaemic compared with normotensive controls. Pollare T et al. Metabolism 1990, 39(2):167-174.

About 20% of patients with hypertension will develop type 2 diabetes in a three year period. Bosch J et al. N Engl J Med 2006, 355(15):1551-1562.

Fasting glucose levels increase in older adults with hypertension regardless of treatment type. BarzilayJ I et al. Arch Intern Med. 2006;166:2191-2201

The RAS itself plays imp. role in the development of diabetes.

Over activity of RAS appears to be linked to reduced insulin and glucose delivery to the peripheral skeletal muscle and impaired glucose transport and response to insulin signalling pathways, thus increasing insulin resistance.

Jandeleit-Dahm KA et al. J Hypertens 2005, 23(3):463-473.

Activation of a local pancreatic RAS, in particular within the islets, may represent an independent mechanism for the progression of islet cell damage in diabetes.

Diabetes promotes both the development and adverse impact of cardiovascular disease (CVD) risk factors (e.g. hypertension, dyslipidemia, renal dysfunction) and, as a consequence, accelerates cardiovascular age.

Persons with diabetes generally have a cardiovascular age 10 to 15 years in advance of their chronological age.

Advanced cardiovascular age substantially increases both the proximate and lifetime risk for CVD events, resulting in a reduced life expectancy of approximately 12 years.

ACCORD trial , >4700 patients were assigned to intensive- ( achieved mean SBP 119mmHg) or standard treatment ( mean SBP 134mmHg) over a mean follow-up of 4.7 years.

The proportion of patients with serious side-effect- such as hypotension and declining renal function_ increased from 1.3 to 3.3% with aggressive treatment.

Since the risk-benefit ratio tipped towards harm, this study does not support a reduction of systolic BP below 130mmHg.

20,358 individuals studied, 1549 (7.6%) had CKD

Bangalore et al. reported a meta-analysis of 13 RCTs with 37 736 patients with DM,IFG or IGT who, in the intensive group, had a systolic pressure ≤135 mm Hg and, in the standard group, ≤140 mmHg.

The more intensive control related to a 10% reduction in all-cause mortality (95% CI 0.83–0.98), a 17% reduction in stroke but a 20% increase in serious adverse events. Systolic BP ≤130 mmHg was related to a greater reduction in stroke but did not affect other cardiovascular events.

Summary

Goals People with diabetes and hypertension

should be treated to a systolic blood pressure goal of <140 mmHg

Lower systolic targets, such as <130 mmHg, may be appropriate for certain individuals, such as younger patients, if it can be achieved without undue treatment burden

Patients with diabetes should be treated to a diastolic blood pressure <80 mmHg

Recommendations: Hypertension/Blood Pressure Control

ADA. VI. Prevention, Management of Complications. Diabetes Care 2014;37(suppl 1):S36

ADA 2014ADA 2014

Treatment Patients with blood pressure >120/80 mmHg

should be advised on lifestyle changes to reduce blood pressure

Patients with confirmed blood pressure higher than 140/80 mmHg should, in addition to lifestyle therapy, have prompt initiation and timely subsequent titration of pharmacological therapy to achieve blood pressure goals

Hypertension / BP control

• Screening and diagnosis– BP should be measured at every diabetes related visit and at least twice a

year.– Patients found to have elevated BP should have high BP confirmed on a

separate day.– Threshold for diagnosing hypertension in person with diabetes is BP ≥130/80

mmHg (may consider SBP up to 140 in elderly). – Target for treating BP is <130/80.

• Lifestyle therapy for elevated BP– Weight loss if overweight– DASH-style diet with reduced sodium and increased potassium intake– Moderation of alcohol intake– Increased physical activity

SummarySummary Routine treatment of type 2 diabetic patients

with Perindopril-indapamide resulted in:

• 14% reduction in total mortality• 18% reduction in cardiovascular death• 9% reduction in major vascular events• 14% reduction in total coronary events• 21% reduction in total renal events

Benefits appeared to be similar in all major subgroups. Treatment was very well tolerated, with few side effects

and adherence similar to that with placebo.

• Increased HTN control • Reduced hypokalemia • Cardioprotective • Increased adherence

Which combination ? Which combination ? ADVANCE trial

HTN in DM: Therapy

Which combination ? Which combination ?

The Avoiding Cardiovascular Events through Combination Therapy in Patients Living with Systolic Hypertension (ACCOMPLISH) trial indicated that the calcium channel antagonist amlodipine is superior to hydrochlorothiazide in combination treatment with an ACE-I.

In 6946 patients with DM, the number of primary events was 307 in the group treated with amlodipine and 383 in the group treated with hydrochlorothiazide as the add-on to benazepril (P = 0.003), despite a similar reduction of blood pressure in both groups.

In the Aliskiren Trial in Type 2 Diabetes Using Cardio-Renal Endpoints (ALTITUDE) trial, the addition of aliskiren to RAAS blockade in patients with T2DM at high risk for cardiovascular and renal events did not result in a decrease in cardiovascular events and may even have been harmful.

Who Should Receive ACEi or ARB Therapy?

• Clinical Macrovascular disease [grade A, level A] or

• ≥55 years of age [grade A, level A for those with additional CVD risk

factors or end organ damage; grade D, consensus for all others] or • Microvascular disease [grade D, consensus]

At doses that have shown vascular protection [perindopril 8 mg daily (EUROPA), ramipril 10 mg daily

(HOPE), telmisartan 80 mg daily (ONTARGET)]

Among women with childbearing potential, ACEi or ARB should only be used in the presence of proper preconception

counseling & reliable contraception. Stop ACEi or ARB either prior to conception or immediately upon detection of pregnancy

HTN in DM is serious; So manage aggressively ( new Target <140/80mmHg)

TLC, Lipid control, Glycemic targets – VP is a must

drugs that act on the RAA axis are recommended for first-line use

ACE inhibitor should be considered first, but ARB should be substituted if ACE inhibitor not tolerated

MAU/ACR must for all DM – Predict CAD, CKD

Typically 2 or more drugs are needed for HTN Rx.
