Introduction Hazard ratio for coronary heart disease mortality for SMI patients versus controls (18-49 yrs) 3.22 (95% CI 1.99-5.21) (Goodwin 2009 23:4 ) Hazard ratio for stroke 2.53 (95% CI 0.99-6.47) (Goodwin 2009 23:4 ) For every 30 people who gain 4kg of weight, one will develop hypertension in the next 10 years Approx up to 70% of mental health patients smoke

Background to Bipolar Disorder and Cardiac Risk (1) Patients with bipolar 1 may have double the cardiovascular risk of bipolar 2. After suicide and accidents, cardiovascular/all vascular diseases are leading cause of death in bipolar patients 17% have type 2 diabetes and 35% have hypertension (Goodwin 2009 23:4 )
Background to Bipolar Disorder and Cardiac Risk (2) One study of outpatients with bipolar disorder (n=118, mean age 53 years) 84% had hyperlidaemia, 70% had hypertension and 25% had diabetes Clinically significant depressive symptoms raised odds of framingham score > 20%, 6 fold Depressive symptoms were also associated with increased BMI, glucose and BP Slomka JM et al. 2012; 138(3)

Mood stabilisers and cardiac risk (1) Lithium Lithium contra-indicated in cardiac disease Lithium usually benign cardiac side-effects in 20-30% of patients On average starting Lithium can increase QTc by 18.6msecs Weight gain is 2 nd highest reason for non-compliance with lithium (most often in 1 st two years) Significant weight gain (>7%) Odds ratio versus placebo of 1.89 (95% CI 1.27-2.82, p = 0.002). (McKnight R et al 2012; 379) Weight gain of lithium versus olanzapine odds ratio 0.32 (95% CI 0.21-0.49, p< 0.0001, n=285) (McKnight R et al 2012; 379) Lithium versus aripiprazole over 52 weeks +0.74kg against +0.97kg (McIntyre RS et al. 2011; 13(6) )
Mood stabilisers and cardiac risk (2) Weight gain - clozapine/olanzapine > quetiapine/risperidone > lithium/valproate (Choong E et al. 2012 46(4) ) Others Carbamazepine can cause a rise in cholesterol, HDL and LDL Valproate and carbamazepine can cause weight gain Topiramate and lamotrigine don t cause weight gain

Monitoring of patients with Bipolar Disorder Everyone should have: - weight, diet, nutritional status - CVS status inc BP and pulse - Blood glucose and lipids - Liver - U&Es, TFTs and Ca 2+ for people on Li NICE sept 2014
Background to Depression and Cardiac Risk Patients with coronary heart disease have 3 times the risk of depression over general population Depressed patients are 2.7 times more likely to die from ischaemic heart disease (Surtees G et al. 2008: 165) Following acute coronary syndrome those who have severe depression have a doubling of their mortality over seven years over those without depression (hazard ratio 2.3 95% CI 1.28-4.14) (Glassman A, Bigger Jnr TJ, Gaffney M. 2009;66(9) Diabetes doubles the odds of co-morbid depression
Depression and future cardiac disease Swedish twins study, 36654 twins Depression and antidepressant use associated with CVD development Risk highest in depressed patients who didn t use antidepressants (HR 1.48, CI 1.10-2) When the CVD outcomes were split, the association was found with ischaemic stroke but not for coronary heart disease *Rahman I et al. 2013;28(7)
Surtees G et al. 2008: 165
ENRICHD study Antidepressant drug use was associated with a lower risk for death or nonfatal MI of an adjusted HR of 0.63 (95% CI, 0.46-0.87) and decreased risk of dying, with an adjusted HR of 0.63 (95% CI, 0.42-0.94).(Writing committee 2003;289) SADHEART sertraline v placebo over 2 years post MI - incidence of severe cardiovascular adverse events was 14.5% with sertraline and 22.4% with placebo (Glassman A et al. 2002;288) 7 year follow up of SADHEART - baseline depression severity (hazard ratio, 2.30; 95% confidence interval, 1.28-4.14; P <.006) and failure of depression to improve with either sertraline or placebo (hazard ratio, 2.39; 95% confidence interval, 1.39-2.44; P <.001) were strongly and independently associated with longterm mortality (Glassman A et al. 2009;66(9))

Antidepressants and weight gain (1) Weight gain or loss can be part of depression One study showed patients on antidepressant gained 1kg of weight over 12 year period Patten S et al. 2011; 134(1-3) Tricyclic antidepressants increased craving and decreased metabolic rate SSRIs tend to get weight loss initially over first month followed by weight gain in the long term Mirtazapine causes weight gain MAOIs can cause weight gain Least weight gain agomelatine, trazodone or reboxetine, venlafaxine or duloxetine

Conclusion When considering the choice of medication for patients consider relevant cardiac risk factors and comorbidities Monitor the physical health side-effects of medication prescribed e.g. Lipids, glucose, weight gain, ECG
