Machine learning and blood pressure.

Area of Science:

• Cardiovascular Research
• Artificial Intelligence in Medicine
• Biomedical Data Science

Background:

• Machine learning (ML), a subset of artificial intelligence (AI), excels at pattern recognition.
• ML algorithms are increasingly applied to predict cardiovascular risk factors, including blood pressure (BP).
• Since 1999, ML, initially with neural networks, has been used to analyze BP and pulse wave relationships.

Purpose of the Study:

• To explore the expanding applications of ML in cardiovascular risk assessment.
• To investigate the use of ML in estimating biochemical measures and anti-hypertensive regimen effectiveness.
• To highlight the potential of ML in re-analyzing clinical trial data for novel insights.

Main Methods:

• Utilizing supervised and unsupervised learning algorithms for pattern recognition.
• Integrating cardiometabolic risk factors (e.g., BMI, waist circumference) with BP data.
• Applying ML to large clinical trial datasets (e.g., SPRINT) for re-analysis.

Main Results:

• ML has been expanded to incorporate diverse cardiometabolic factors and pharmaceutical agents.
• ML methods estimate biochemical markers (HDL, LDL, cholesterol, fibrinogen, uric acid).
• ML aids in evaluating the effectiveness of anti-hypertensive treatments and unearthing new predictor-outcome relationships.

Conclusions:

• AI and ML are gaining significant traction in chronic disease management.
• Elevated blood pressure is a critical early indicator of cardiovascular and renal injury risk.
• Advancements in AI and ML promise improved early disease prediction and timely intervention.
