After several years studying the subject of cardiovascular disease early in life and with some papers published recently about it (1-5) I can say that nowadays, as health care providers, we are facing several cardiovascular disease contributing risk factors (hypertension, obesity, smoking, unhealthy diet, etc.) which prompts a large burden on our shoulders as they keep leading to a long-lasting and quite steady worldwide prevalence of heart conditions, stroke, kidney failure, premature death and disability for the last 20 years. (6)
Even, children and adolescents are not spared from this. For instance, according to the latest European (7) and North American Guidelines about the subject (8), the prevalence of high blood pressure in children and adolescents ranges between 3 to 11 % and rises up to 40 % when obesity is in place as well.
The above mentioned is a known fact that unfortunately is ongoing with some ups and downs but continue to be a pending endeavor yet to be solved by the medical community. Thus, I do not want to dwell on it on this post.
At the moment, I am more interested on reflecting how these spotlighted main risk factors might be blindfolding us from seeing “little facts” that are having also an impact on the complex setting related with the development of cardiovascular disease and sadly are often overlooked.
In this light, there is one fact which is not as publicized as the main risk factors mentioned above which is critical my opinion. I am referring to the buccal hygiene and its links to cardiovascular disease.
To get started, it is worth mentioning that the surfaces of the human body are heavily colonized by a varied microbial ecosystem called the microbiota, in other words, this is a mixed community of microorganisms composed of bacteria, viruses, archaea, and eukaryotic microbes that coinhabit in our body . The gathering of those microbes and their genes is named the human microbiome and each person has a unique microbiome which varies along with our genetic background, age and life style (9)
As per the aim of this paper, I will point out at the oral microbiome, which is considered one of the most highly dynamic ecosystems in the human body.
According to the latest investigations, the estimated number of bacteria in the mouth is up to 100 billion and comprised nearly 700 identified bacterial species being the most prevalent Firmicutes and Proteobacteria, along with Bacteroidetes, Actinobacteria, and Fusobacteria (10)
Though, the oral microbiome is dynamic in terms of functioning, as ecosystem must be stable in its composition and structure. Any disruption in it leads to a state called dysbiosis.
Recently, multiple animal and human studies have examined the relationship between the oral microbiome disruption (dysbiosis) and blood pressure and have reported important insights explaining such links.
The most important proposed links to hypertension would be the following:
- Increasing sympathetic nervous system activity.
- Inflammation and endothelial dysfunction with vascular remodeling (11)
The above links, in turn are known triggering factors for high blood pressure through complex mechanisms beyond the scope of this article.
Now, I will lay out a question: How many time have you been asked by a doctor (no a dentist) in a clinic when feeling some cardiac-like symptoms about your buccal hygiene habits?
The response to this question will come later… Continue reading “Poor buccal hygiene might lead to an acute myocardial infarction. Time to make the difference.”
