• Metabolic syndrome
• Syndrome X
• Insulin resistance syndrome
• Deadly quartet
• Reaven’s syndrome
6. International Diabetes Federation Definition:
Abdominal obesity plus two other components: elevated BP, low HDL, elevated TG, or
impaired fasting glucose
7. The major features of metabolic syndrome include
Central obesity
Hypertrilgyceridemia
Low high density lipoprotein (HDL)
Hyperglycemia
hypertension
8. EPIDEMIOLOGY
• Prevalence increases with age
• Greater industrialization and urbanization
• Increase in waist circumference is found predominantly in women.
• Fasting TG>150 mg/dl and hypertension more likely in men.
9. Risk factors
• Overweight/ obesity- central (key feature)
• Sedentary lifestyle
Predictor of CVd events and associted mortality
Associated with central obesity, TG’s, HDL, BP, glucose intolerance
• Aging- prevalence increases with age
• Diabetes mellitus- approx. 75% of T2DM or IGT have metabolic syndrome
• Coronary heart disease- 50% of CHD patients have metabolic syndrome
•
• About 1/3rd of MS patients have premature CAD
• Lipodystrophy- both genetic or acquired have severe insulin resistance
10. CLINICAL FEATURES
• Usually asymptomatic and a high index of suspicion is needed for
diagnosis
• Examination -
Increased waist circumference
Increased Blood Pressure
Lipoatrophy
Acanthosis nigricans/ skin tags
Should alert to search
for other abnormalities
15. BP Reductions as Little as 2 mm Hg
Reduce the Risk of CV Events by Up to 10%

20. Blood pressure (ADA 2019)
• BP should be measured at every routine clinical visit.
• Patients found to have elevated BP (≥140/90) should
have BP confirmed using multiple readings, including
measurements on a separate day, to diagnose
hypertension.
• Most patients with DM & hypertension should be
treated to a SBP goal of <140 mmHg & a DBP goal of
<90 mmHg.

32. 90% of ACE is a tissue enzyme present in the heart and vessel
( endothelium and smooth muscle )
CAD up-regulates tissue ACE and alters the balance between:
Angiotensin II
Bradykinin
which, in turn, impairs endothelial function
ACE activity and endothelial function
35. Angiotensin II Antagonists
Advantages over ACE Inhibitors
AT-1 receptors are blocked in all tissue (heart, vascular
endothelium, kidney and the brain) regardless of the alternative pathways of the
formation of Angiotensin II.
e.g. Chymase enzymes in the heart.
No dose adjustment is required in renal impaired patients
No bradykinin accumulation, but normal bradykinin release is
present.
No Cough
Complete blockade of the pathological effects of Angiotensin II
through AT-1 receptor blockade.
36. Angiotensin II Antagonists
Advantages over ACE Inhibitors
Angiotensin II remaining in the tissues - in relative excess - fit in the
AT-2 receptors inducing beneficial effects
Vasodilatation
platelet aggregation;
proliferation of vascular SMC.
Angiotensin II is converted to Angiotensin (1-7) which
stimulates “Nitric O” production directly irrespective of
bradykinin.
“Nitric O” leads to a series of beneficial effects:
Vasodilatation
platelet aggregation
Anti - proliferate effect
37. Specific selective blockade AT1-receptor
Blocks also non-ACE produced A II
Stimulation of the AT2-receptor

Not all ARBs are the same
The more selectivity,
The more blockage of AT1receptors,
The more AngII will act on beneficial AT II
