CV risk assessment
Are you satisfied with this CV risk determination or do you believe it is important to perform adjunctive tests?
1) Yes, I am satisfied
2) No, it is necessary to perform an echocardiogram
3) No, it is necessary to perform an ultrasound
4) No, it is necessary to perform an ABPM
![Page 11: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/11.jpg)
Clinical case
This patients could be managed without adjunctive tests. However, expecially in a specialistic center, it is convenient to better characterize the CV risk profile.
![Page 12: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/12.jpg)
Echocardiogram
• Concentric LVH (LMVS 58 g/m2.7;
LVMI: 148 g/mq; RWT: 0.47).
• Increased left atrial (44 mm)
• Normal contractility (EF 56%)
• Diastolic dysfunction (E/A= 0.6)
• Mild mitral failure lieve (+)
• Mild tricuspidal failure (+)
![Page 13: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/13.jpg)

Clinical case
Tests confirm that this patient is at high CVrisk.
![Page 15: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/15.jpg)
CV risk assessment
In this patient would you perform an abdomen echography and/or a renal artery doppler?
1) No
2) Only an abdomen echography
3) Only a renal artery doppler
4) Both
![Page 16: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/16.jpg)
Indications for renal arteries doppler
High risk for abdominal aorta aneurysm (male, smoker, hypertensive, positive family history).
Indications for abdominal echography
High risk for renal artery stenosis (smoking and diabetes)
![Page 17: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/17.jpg)
Renal arteries doppler
Mild-moderate hepatic hypertrophic steatosis. Normal adrenals and kidneys. Atherosclerotic plaques at the level of abdominal aorta.
Abdominal echography
No renal artery stenosis, normal renal perfusion, increased vascular resistance indices
![Page 18: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/18.jpg)
Diagnosis
•Essential arterial hypertension with high CV risk
•Global cardiovascular risk: family history for CV disease, smoking habitus, diabetes, hypercholesterolemia, sedentary life
•Target organ damage: LVH, carotid artery IMT and plaque
![Page 19: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/19.jpg)
Treatment
•Life style modifications: low calories and low cholesterol diet; dynamic exercise; smoking cessation
•Antihypertensive treatment: any compelling evidence?
•Need for accompanying non-antihypertensive treatment: Statins?
Antiplatelet therapy?

BP target
In a patient with hypertension and diabetes it should be mandatory to lower BP values well below 140-90 mmHg.
The more aggressive target of less than 130-80 mmHg should be individually considered.
![Page 30: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/30.jpg)
Treatment
What is the first choice drug for this patient?
1) ACE-inhibitor
2) AT-1 antagonist
3) Calcium antagonist
4) Beta-blocker
5) Diuretic

TreatmentWhich strategy do you suggest to improve the efficacy of
antihypertensive treatment?
Proposal:
•Combination of an ACE-inhibitor at full dose with a DHP calcium antagonist
Rational:
•The most effective combination in hypertensive patients with no negative metabolic effects

Case study: follow-up management
Following the administration of ramipril 10 mg plus amlodipine 5 mg for 4 weeks patient’s BP is now 140/90 mm Hg
Question
What action do you now take?
1. Nothing, the BP reduction is good enough
2. Increase the dose of amlodipine
3. Add a third drug
![Page 55: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/55.jpg)
Antiplatelet therapy
Antiplatelet therapy should be given to patients:
With a history of CV events
>50-year-old with any elevation of serum creatinine or a 10-year CV risk of ≥20%
In hypertensive patients, good BP control should be achieved before commencing antiplatelet therapy

What are the treatment goals for cholesterol in type 2 diabetes ?
1) LDL-Cholesterol < 1.8 mmol/l
2) LDL-Cholesterol < 2.5 mmol/l
3) LDL-Cholesterol < 3.0 mmol/l
4) Consider others (HDL-Cholesterol, triglycerids ?)

SHARP: Rationale/ background
• patients with CKD: high risk of vascular events
• Pattern of vascular disease atypical -> large proportion non-
atherosclerotic
• high statin doses : increased risk of myopathy, especially in patients
with impaired renal function
• Previous trials : inconclusive
(Atorvastatin 20 mg (4D) , Rosuvastatin 10 mg (AURORA):
nonsignificant relative risk reduction of 8% and 4% respectively)

• History of chronic kidney disease
• Not on dialysis elevated creatinine on 2 occasions:
• Men: ≥1.7 mg/dL (150 µmol/L)
Women: ≥1.5 mg/dL (130 µmol/L)
• On dialysis haemodialysis or peritoneal dialysis
• Age ≥ 40 years
• No history of myocardial infarction or coronary revascularization
• Uncertainty: LDL-lowering treatment not definitely indicated or
contraindicated

- Diabetic dyslipidemia is a cluster of lipid abnormalities
- In 50 % in patients suffering from type 2 diabetes:
- High triglycerids
- Low HDL-Cholesterol
![Page 82: Hypertension and diabetes: Case based managementassets.escardio.org/assets/Presentations/OTHER2013/Davos... · 2013-03-14 · Hypertension and diabetes: Case based management Prof.](https://reader031.fdocuments.net/reader031/viewer/2022013020/5e6afd036585141cf9023a25/html5/thumbnails/82.jpg)
Triglycerids
FIELD trial: No effect on primary endpoint (CAD death or non-
fatal MI), but significantly reduced CVD events by 11%
ACCORD trial: Patients with high TG and low HDL-Cholesterol
benefit from adding fenofibrate
HDL-Cholesterol
If lower than < 1.0 mmol/L and TG elevated >1.8 mmol/l
According to 4S trial: Increased risk for major coronary
events (not on mortality)
