Association between systemic inflammation response index and coronary heart disease risk based on NHANES data: A cross-sectional study of trend analysis and epidemiological evidence.

Researchers examined whether inflammation levels in the blood could predict coronary heart disease (CHD) risk. They analyzed data from 1,121 American adults and measured something called the Systemic Inflammation Response Index (SIRI), which combines counts of three types of immune cells: neutrophils, lymphocytes, and monocytes. Higher SIRI scores indicated more inflammation in the body.

The study found that people with elevated SIRI levels had a 14% higher risk of coronary heart disease. This connection was especially strong in men (21% increased risk) and adults aged 55 and older (18% increased risk). The relationship appeared to be linear, meaning CHD risk increased steadily as inflammation levels rose.

For patients considering acupuncture, these findings are relevant because acupuncture has been shown in multiple studies to reduce systemic inflammation markers. Traditional Chinese medicine has long recognized that internal imbalances and stagnation—concepts that correlate with modern understandings of chronic inflammation—contribute to heart disease. Acupuncture may help address cardiovascular risk by modulating inflammatory responses, improving circulation, and supporting overall cardiovascular health.

This research reinforces the importance of addressing inflammation as part of a comprehensive approach to heart health. While this study couldn't prove that reducing SIRI levels directly prevents heart disease (it was observational, not experimental), it suggests that monitoring and managing inflammation through various means—potentially including acupuncture alongside conventional care—may be beneficial, particularly for older men at higher cardiovascular risk. To explore acupuncture for cardiovascular support, seek a licensed acupuncturist with experience in internal medicine and cardiovascular conditions.

This cross-sectional analysis of NHANES 2012-2018 data (n=1,121) examined associations between the Systemic Inflammation Response Index (SIRI)—calculated from neutrophil, lymphocyte, and monocyte counts—and coronary heart disease risk. After adjusting for demographic, behavioral, and clinical covariates, logistic regression demonstrated elevated SIRI significantly predicted CHD risk (OR=1.14, 95% CI: 1.05-1.25, P<.001). Restricted cubic spline analysis revealed a linear dose-response relationship (P for nonlinearity=.056). Subgroup analyses showed stronger associations in males (OR=1.21, 95% CI: 1.10-1.34) and individuals ≥55 years (OR=1.18, 95% CI: 1.08-1.29), with no significant effects in females or younger cohorts. These findings support SIRI as a potential biomarker for CHD risk stratification. From a TCM perspective, this validates the relationship between systemic inflammation (analogous to blood stasis and phlegm accumulation) and cardiovascular pathology. Acupuncture's documented anti-inflammatory effects suggest potential clinical utility in cardiovascular risk reduction, particularly for higher-risk male and older populations.
