Challenges in ischaemic heart disease: not sleeping enough, not brushing your teeth, and skipping breakfast—three ways of increasing your risk of myocardial infarction?

Despite optimal medical therapies, there is currently a persistent residual cardiovascular risk. The most likely pathway responsible for this residual risk has been identified in the inflammatory state. Recent studies have confirmed that inflammation increases cardiovascular risk independently from LDL cholesterol levels. Addressing traditional risk factors, such as obesity, cigarette smoking, diabetes, arterial hypertension, and dyslipidaemia, also provides an important reduction of the levels of inflammation. Nonetheless, inflammation is also a target for specific and focused therapeutic interventions. Recent studies have outlined an association between oral hygiene, sleep deprivation, and nutritional patterns on the one hand, with the development of multi-districts atherosclerosis and/or adverse cardiovascular events on the other. These lifestyle patterns appear to be involved in fostering inflammation associated with atherosclerosis. There is, however, a persistent need for further studies to clarify whether such associations with cardiovascular disease are direct and causal, and if they are all channelled through vascular inflammation.
