Blood Pressure Variability and Heart Attack Risk

Blood Pressure Variability is a Major Predictor of Heart Attack and Stroke Risk, Finds Analysis

High blood pressure, also known as hypertension, is a common health condition that affects millions of people worldwide. It is a major risk factor for heart attacks and strokes, leading causes of death globally. However, recent research suggests that blood pressure variability may be an even stronger predictor of these cardiovascular events.

The Link Between Blood Pressure Variability and Cardiovascular Risk

Blood pressure variability refers to the fluctuations in blood pressure levels over time. While it is normal for blood pressure to vary throughout the day, excessive variability can indicate an underlying health issue. A study published in the Journal of the American College of Cardiology analyzed data from over 9,000 individuals and found that those with higher blood pressure variability had a significantly higher risk of heart attacks and strokes.

The researchers discovered that individuals with greater blood pressure variability were 46% more likely to experience a heart attack and 33% more likely to have a stroke compared to those with stable blood pressure levels. These findings suggest that blood pressure variability should be considered as an important factor in assessing cardiovascular risk.

Implications for Prevention and Treatment

Identifying blood pressure variability as a major predictor of heart attack and stroke risk has significant implications for prevention and treatment strategies. Healthcare professionals can now focus on monitoring not only average blood pressure levels but also the variability over time. This information can help identify individuals who are at a higher risk and implement appropriate interventions.

Moreover, lifestyle modifications such as regular exercise, a healthy diet, stress management, and medication adherence can play a crucial role in reducing blood pressure variability. By addressing this variability, individuals can potentially lower their risk of cardiovascular events and improve their overall health.


Understanding the impact of blood pressure variability on heart attack and stroke risk is a significant advancement in cardiovascular research. By recognizing the importance of monitoring blood pressure fluctuations, healthcare professionals can better assess an individual’s risk and provide targeted interventions. Additionally, individuals can take proactive steps to manage their blood pressure variability through lifestyle changes and medication adherence. Together, these efforts can contribute to a healthier population with reduced cardiovascular risks.
