Increased mortality in schizophrenia due to cardiovascular disease – a non-systematic review of epidemiology, possible causes, and interventions

Background: Schizophrenia is among the major causes of disability worldwide and the mortality from cardiovascular disease (CVD) is significantly elevated. There is a growing concern that this health challenge is not fully understood and efficiently addressed.

Methods: Non-systematic review using searches in PubMed on relevant topics as well as selection of references based on the authors’ experience from clinical work and research in the field.

Results: In most countries, the standardized mortality rate in schizophrenia is about 2.5, leading to a reduction in life expectancy between 15 and 20 years. A major contributor of the increased mortality is due to CVD, with CVD mortality ranging from 40 to 50% in most studies. Important causal factors are related to lifestyle, including poor diet, lack of physical activity, smoking, and substance abuse. Recent findings suggest that there are overlapping pathophysiology and genetics between schizophrenia and CVD-risk factors, further increasing the liability to CVD in schizophrenia. Many pharmacological agents used for treating psychotic disorders have side effects augmenting CVD risk. Although several CVD-risk factors can be effectively prevented and treated, the provision of somatic health services to people with schizophrenia seems inadequate. Further, there is a sparseness of studies investigating the effects of lifestyle interventions in schizophrenia, and there is little knowledge about effective programs targeting physical health in this population.

Discussion: The risk for CVD and CVD-related deaths in people with schizophrenia is increased, but the underlying mechanisms are not fully known. Coordinated interventions in different health care settings could probably reduce the risk. There is an urgent need to develop and implement effective programs to increase life expectancy in schizophrenia, and we argue that mental health workers should be more involved in this important task.

Maybe the stress of the illness promotes atherosclerosis and plaque buildup over cortisone imbalances?

Maybe it’s because a lot of schizophrenics just don’t exercise or watch what they eat. Also, a lot of us smoke. Add that up and it spells heart attack.

There is a general weakening of the body for most sz’s when they have to take anti-psychotic medication. It follows that the heart might be weakened too.

Not just poor diet and smoking, many of the Schizophrenic have chronic fatigue and low motivation for physical exercise which may increases the risk for cardiovascular disease. Also one of the side effects of antipsychotics is high cholesterol in blood.

I think when it comes to diet and exercise many may lack motivation which may be an illness thing or an adverse effect of the medication. Also organising yourself to eat healthily may be a problem.
I know I am poor in terms of diet and exercise. They want me to eat more vegetables/fruit and have a breakfast coupled with walking 20-30 minutes a day
How I am going to eat more veg I don’t know as I mainly have ready meals that are light on veg. Unless I do a portion of veg with each ready meal . For fruit I buy several packs of frozen(mango/pineapple/black cherry/fruit salad/forest fruits etc) a week.
The walking is also an issue as I am not one for just going out by myself and aimlessly walking for x amount of time. One thing I do have is my exercise bike.
Of course one thing that would help is if they made meds that didn’t (a) increase your appetite and (b) zap your motivation to do anything about it and © if you get past b don’t make it hard to shift the weight anyway . The last time I got motivated to try losing weight I lost just 6lbs in 12 weeks. Realising it would take me 3 years or more at that rate to get to an ideal weight I gave up. I just couldn’t face 3 years of it.

Not to mention the damage of what many of us have done in the way of self medicating or self destruction.
