Psychiatric mental health disorder: a cause of cardiovascular disease

Husna, Amity University Kolkata

A psychiatric disorder is a mental illness that greatly disturbs an individual’s thinking, moods, or behavior and can even seriously increase the risk of disability, pain, and death. Studies have shown that negative emotions, along with psychiatric disorders and depression can increase the risk of cardiovascular diseases (CVD) incidences and even mortality. In fact, people with depression are twice as likely to develop myocardial infarction when compared with the general population. Death from heart disease among depressed people occurs even more than suicidal deaths.

 According to the World Health Organization (WHO), lifestyle is a combination of behavioral patterns and individual habits throughout life. Several factors play a role in the relationship between depression and CVD. One of them is oral and dental hygiene which is an indicator of general health and quality of life. So, a large data consisting of 10,065 individuals aged 35–65 years old from a cohort study in Kurdish region aimed to find the direct effect of psychiatric disorder on CVD, and also the role of oral and dental hygiene as a mediator between psychiatric disorders and cardiovascular diseases was investigated.

It was found that as oral lesions are directly related to the mental status of individuals so poor oral and dental hygiene including periodontal disease and tooth decay are associated with an increased risk of cardiovascular disease. This is due to the fact that psychiatric disorders, such as depression and stress can affect the periodontium, the internal tissue of mouth since it has a direct connection with the blood and vascular system. 

In conclusion, psychiatric disorders are directly associated with cardiovascular disease. It was observed that in case of optimal situation of hygiene behaviors and oral lesions in the presence of psychiatric disorder there was a higher chance of getting CVD, as compared to the absence of psychiatric disorders. So these results suggested that mediating people with psychiatric disorders can decrease the prevalence of CVD.
