Research has shown that long-term blood pressure fluctuations can increase the risk of sudden cardiac death. [사진=게티이미지뱅크]Research has shown that long-term blood pressure fluctuations can increase the risk of sudden cardiac death. According to the results of this study, the risk of sudden cardiac death increased by up to 70% in the group with the highest blood pressure fluctuation compared to those with the most consistent blood pressure.
Several existing studies have shown that uncontrolled high blood pressure significantly increases the risk of heart disease, stroke, dementia, and other chronic diseases. The study looked at the association between blood pressure variability and the risk of sudden cardiac death, regardless of whether blood pressure was high or low.
The researchers analyzed data from 23,499 adults with an average age of 53 at the start of the study. The people had their blood pressure measured three or more times over an average period of 15 years, and the researchers followed them for up to 30 years. The highest blood pressure, systolic blood pressure, showed an average difference of about 11 to 12 mmHg, and the lowest blood pressure, diastolic blood pressure, showed a difference of about 7 mmHg.
As a result of the analysis after adjusting for factors that could affect the results, it was found that the risk of sudden cardiac death increased by 3% for every 1 mmHg increase in systolic blood pressure variability. Compared to those with the most consistent blood pressure levels, those with the most volatility had a 40 to 70 percent higher risk of sudden cardiac death. These results were independent of whether the blood pressure was high or low at first or how much it rose with age.
“Blood pressure variability is not simply a number on a chart,” said Ritam Patel of Northwestern University Feinberg School of Medicine, the lead researcher of this study. “This tells us powerful facts about hidden risks that we have not been able to quantify before,” he said. “For the millions of people who measure their blood pressure, there is an incentive to strive to maintain stability beyond the blood pressure readings.”
“This study shows that tracking blood pressure variability can help identify and prevent people at highest risk for sudden cardiac death,” said cardiologist Donald Lloyd-Jones, MD, professor of preventive medicine at the Feinberg School of Medicine and senior investigator on the study. “The results provide an opportunity to save lives before the condition becomes too serious,” he said.
Although the study did not explore the mechanisms or reasons why blood pressure fluctuations affect heart health, Dr. Lloyd-Jones said one possible explanation was the extra strain that blood pressure fluctuations place on the body. “Our bodies are designed to respond to stimuli, and it often takes hours or days for these responses to occur,” he said. “Whether it is weight or blood pressure, the yo-yo effect requires a continuous response, so the body needs additional energy.” “It puts pressure on us,” he explained.
The results of this study, which were recently presented at the American Heart Association conference held in Chicago, USA, were published in the American Heart Association academic journal Circulation as ‘Long-Term Blood Pressure Variability is Associated With Risk for Sudden Cardiac Death: Cardiovascular Lifetime Risk Pooling Project (LRPP)’. It was published under the title.

Given that blood pressure volatility can increase the risk of sudden cardiac death, should healthcare providers focus on both reducing average blood pressure and stabilizing blood pressure fluctuations in their patients?
This article highlights a significant health concern: the link between blood pressure volatility and the risk of sudden cardiac death. Here are some open-ended questions to stimulate discussion and explore different viewpoints based on the information presented:
**Theme 1: Understanding Blood Pressure Volatility**
* The article mentions that blood pressure fluctuations can significantly impact heart health. What are your thoughts on our current approach to managing blood pressure? Should we focus more on stability rather than just achieving a certain number?
* Beyond medical interventions, what lifestyle factors might contribute to blood pressure volatility? How can individuals become more aware of their own blood pressure fluctuations?
**Theme 2: Implications for Healthcare and Individuals**
* The research suggests tracking blood pressure variability can help identify individuals at higher risk.
How can we effectively implement this into standard checkups and preventative healthcare practices?
* Knowing that even small fluctuations can increase risk, what steps can individuals take to mitigate their own blood pressure volatility? How can this information empower individuals to take a more proactive role in their heart health?
**Theme 3: Broader Implications and Future Research**
* The article briefly mentions stress as a potential contributor to blood pressure fluctuations.
What other factors might play a role, and how can we address them from both a societal and individual level?
* This research focused on sudden cardiac death. What other health conditions might be affected by blood pressure variability, and what future research could shed light on these connections?
* The study focuses on adults. To what extent might these findings be relevant to children and adolescents?
**Additional Discussion Points:**
* The article concludes with a quote about the “yo-yo” effect of blood pressure fluctuations. How might this analogy resonate with people, and how can it be used to motivate behavior change?
* While the study highlights a serious concern, it also presents a potential opportunity for prevention.
How can we leverage this knowledge to improve public health outcomes and raise awareness about the importance of blood pressure stability?
By exploring these questions, we can foster a deeper understanding of the complex relationship between blood pressure volatility and heart health, encouraging informed discussions and potential actions to improve individual and public well-being.
