Insights
Omega-3 fatty acids may help reduce blood pressure in middle-aged individuals. However, stress and negative emotions can still disrupt blood pressure variability, impacting cardiovascular health.
Area of Science:
- Chronobiology
- Cardiovascular Physiology
- Nutritional Science
Background:
- Circadian variability disturbances are linked to cardiovascular diseases.
- Circadian Hyper Amplitude Tension (CHAT) is a psychosomatic disorder influenced by lifestyle and genetics.
- Blood pressure and heart rate exhibit rhythmic fluctuations influenced by environmental and genetic factors.
Observation:
- A 43-year-old woman's blood pressure and heart rate were continuously monitored for six months.
- The study correlated nutritional intake (omega-3 fatty acids) and psychosocial factors (divorce, PANAS) with cardiovascular rhythms.
- Ambulatory blood pressure monitoring (ABPM) generated 16 Sphygmochron profiles for detailed analysis.
Findings:
- Systolic (SBP) and diastolic (DBP) blood pressure showed a steady decrease over the study period.
- Three instances of elevated SBP variability (CHAT) and one of low DBP occurred during periods of negative affect.
- A correlation was observed between omega-3 fatty acid intake and reduced SBP/DBP, alongside stress-induced blood pressure variability.
Implications:
- Omega-3 fatty acid supplementation may offer a strategy for managing blood pressure in middle-aged adults.
- Psychosocial factors significantly impact cardiovascular variability, highlighting the stress-strain hypothesis.
- Personalized chronobiological monitoring can reveal individual responses to lifestyle interventions and stressors.
Background:
The disturbance of circadian variability helps predict, among others, the occurrence of cardiovascular diseases. Circadian Hyper Amplitude Tension (CHAT) is a psychosomatic disorder related to an inappropriate lifestyle (including unbalanced diet, stress-inducing environment/development) and genetic factors. Blood pressure and heart rate are phenotypes characterized by rhythmic fluctuations over time under influence of environmental/developmental (incl. psychosocial) and genetic conditions. These cardio-/cerebro-vascular fluctuations result from otherwise largely distributed internal biological rhythms regulated via complex and intertwined neuro-hormonal systems.
Objective:
The objective of this study was to identify a potential time-structure relationship between blood pressure/heart rate rhythmic fluctuations and nutritional/psychosocial conditions in a 43-year old woman exposed to new nutritional (omega-3 fatty acids supplementation) and psychosocial (divorce) factors.
Method:
The study involved the use of a non-invasive device (ambulatory blood pressure monitor or ABPM, A&D Ltd, Tokyo, Japan) for continuous (24/7) monitoring of heart functions and rhythms between October 2009 and March 2010, at 30-min intervals. As a result, 16 time-structure profiles (Sphygmochron) were obtained from Halberg Chronobiological Center (Minneapolis, MN, USA), each of them containing detailed analysis and interpretation of stacked data spanning 7-14 days. The study also involved a diary of daily nutritional (omega-3 fatty acids) / psychosocial (PANAS) events and their emotional and cognitive components.
Results:
Both systolic (SBP) and diastolic blood pressure (DBP) steadily decreased during the time of the study. Three periods of elevated variability in SBP (diagnosed as CHAT) and one period of abnormally low DBP were recorded during the 6-month study at the time of negative affects (NA).
Conclusion:
A comparative analysis of diary records (omega-3 fatty acids & PANAS) and cardiovascular responses (Sphygmochron) showed that a person who is professionally and socially active in middle age can actively reduce her SBP/DBP with omega-3 fatty acids intervention. However, the person also displays disturbances in blood pressure variability predicted by the stress-strain hypothesis, whereby states of strain and relaxation are generated by the persons predetermined standards and objectives.
