2. Why?
u The metabolic syndrome is a cluster of interrelated
risk factors for the development of Cardiovascular
disease CVD
u Once the criteria of metabolic syndrome is there, the
prevalence of coronary heart disease (CHD) is
doubled.
u CHD Risk Increases with Increasing Number of Metabolic
Syndrome Risk Factors .

7. Case
u A 62-year-old woman is brought to the emergency
department by paramedics for chest pain that has been
present for 5 hours. Medical history is notable for
DYSLIPEDIMIA . Medications include atorvastatin, and
aspirin.
u On physical examination, she appears comfortable. She
is afebrile, BP is 190/90 mm Hg, PR is 88/min and
respiration rate is 16/min. Cardiac examination shows
no murmurs, extra sounds, or rubs. The lungs are clear
and pulses are equal bilaterally. Neurologic examination
is normal.
8. u The electrocardiogram shows 2-mm ST-segment
elevation in leads I,V2, and V3.
u A coronary catheterization Iis done witin 1 hour.
9. u Current medications are aspirin, clopidogrel,
metoprolol, atorvastatin, and sublingual nitroglycerin.
u 4 weeks later patient started to be isolated , low mood
with frequent guilt feeling and death wishes
u according to the family she had these sx for the last 2
weeks.

11. u In patients with CHD, the prevalence of major
depression is nearly 20% and the prevalence of minor
depression is approximately 27%.
u Francois Lesperance 25% of pt had an MI also gave hx of
MDD.
u 7% occurred in the year prior to the MI.
u 15% started after the MI.
u MDD rates higher around 6 months following MI and
gradually decrease around 1 year.

training, risk factor modification, education,
medical surveillance, vocational rehabilitation,

14. Approach
u Earlier prescription of antidepressants in
the hospital (in coordination with
cardiology) is recommended in the
following circumstances (Huffman et al.
2004).
15. u Depression with suicidal ideation .
u Development of sx during hospitalization.
u History of severe depression.
u Severe depression that inhibits
participation in rehabilitation or self-care
20. u In SADHART, the depression scale ratings did not
improve significantly in the total study population
with sertraline therapy compared with placebo [95].
However, the subset of patients who had a history of
major depression prior to their MI did have
significant improvements in depressive symptoms
with sertraline.

22. u In CREATE, citalopram or placebo [ 89]. After 12
WK of therapy, the citalopram group had a
statistically significant greater decline in a
standard measurement of depression compared
with placebo.
u However, the United States FDA issued warnings
that citalopram causes dose-dependent QT
interval prolongation that can lead to arrhythmias,
and thus recommends avoiding citalopram in
patients with recent acute MI.

30. SSRIs and bleeding
u Risk is increased still further in those also receiving
aspirin, NSAIDs or oral anticoagulants.
u Try to avoid SSRIs in patients receiving NSAIDs, aspirin or
oral anticoagulants or with history of cerebral or GI
bleeds.
u If SSRI use cannot be avoided, monitor closely and
prescribe gastroprotective proton pump inhibitors.
31. u ECG monitoring is essential for all
patients prescribed antipsychotics. An
estimate of QTC interval should be made
on admission to in-patient units (note that
this is recom- mended in the NICE
schizophrenia guideline13) and at least
yearly thereafter.
32. u Measure QTC in all patients prescribed antipsychotics.
u On admission :if previous abnormality or known
additional risk factor, at annual physical health .
u Consider measuring QTc within a week of achieving a
therapeutic dose of a newly pre- scribed antipsychotic
that is associated with a moderate or high risk of QTc
prolonga- tion or of newly prescribed combined
antipsychotics.
33. u In general, a QTc of 440 ms is considered the aver- age
upper limit of normal.
u • An interval of 500 ms or more is a signal to change the
treatment method (Glassman 2002).
u antipsychotics block cardiac potassium channels and are
linked to prolongation of the cardiac QT interval .
u 440msec for men, 470msec for women.

recently.
u The medical team change the AP to quetiapine 200 mg
twice daily and the regimen of the MI meds including
aspirin,clodepigrol and metapronolol.
u 3 days later the patient started to be agitated thinks
that the nurses want to harm him and hearing voices
commanding him to leave the hospital.
u The medical team consult you regarding his agitation.
44. u How will you appaoach this case?
HX,MSE,IX,File review,DD.
u What is your management?
u When will you start treatment?
45. Summary
u ECG must be done in cardiac patient as baseline
and follow up when reaching theraputic dose or
introducing new agent to avoid sudden cardiac
death.
u Average QTC range for male: 440msec, female:
470mse.
u Safest ADs : sertraline,citalopram,mirtazapine and
bupropione.
u All benzodiazepine cosider safe.
46. Summary
u Avoid IV AP and always go with low effect of AP
like olanzapine and resperidone .
u Aripaprizole is the safest AP.
u In polypharmacy always look for drug drug
interactions.
u Consult cardiologist if the patint condition
unstable.
u Almost all SSRIs have antiplatelet effect and
interact with warfarin which increse bleeding
time.
