Atherosclerosis is often described as a single disease with many faces, and a new study of patients with non-ST-segment elevation acute coronary syndrome (NSTEACS) adds weight to that view. In a single-center cross-sectional study, 186 patients with NSTEACS underwent simultaneous computed tomography angiography (CTA) of both the coronary arteries and the cervicocephalic circulation, the arteries supplying the head and neck. The findings, published in the European Journal of Medical Research, indicate that how widely atherosclerosis is distributed across the cervicocephalic vascular beds is more strongly linked to coronary atherosclerotic burden than how severe any single narrowing is.
The researchers quantified coronary atherosclerotic burden using three measures: the coronary artery calcium score (CACS), a CT-derived Gensini score, and a category of vessel disease. Cervicocephalic atherosclerosis was assessed along two dimensions. Severity was captured by the maximal stenosis grade, the degree of the worst focal narrowing. Extent was captured by bilateral involvement, combined extracranial and intracranial disease, combined anterior and posterior circulation disease, and the number of stenotic segments with at least 50 percent narrowing. Multivariable regression analyses then evaluated the associations between these cervicocephalic characteristics and coronary burden.
The headline result is striking. Of the 186 patients, 116, or 62 percent, had cervicocephalic stenosis of at least 50 percent. Patients with cervicocephalic atherosclerosis carried a markedly higher coronary burden than those without it. Their median CACS was 524, compared with 93 in patients without cervicocephalic disease, and their median Gensini score was 53 versus 23, with both differences statistically significant at p < 0.001. Multivessel coronary disease was also more prevalent in the group with cervicocephalic atherosclerosis.
When the analysis turned to which cervicocephalic measure best tracked coronary burden, extent-related parameters outperformed severity measures. In multivariable analysis, extent parameters showed stronger associations with the Gensini score than severity did. Bilateral stenosis, combined extracranial and intracranial involvement, and the number of stenotic segments all remained significantly associated with the Gensini score even after additional adjustment for the maximal stenosis grade, meaning that the relationship was not simply explained by how tight the worst narrowing happened to be.
The pattern held across the spectrum of coronary disease. When patients were grouped into quartiles of the Gensini score, all extent parameters increased progressively from the lowest to the highest quartile, with all p values for trend below 0.001. Severity, by contrast, showed only a non-significant trend across the quartiles, with a p value of 0.068. In other words, as coronary burden rose, the spread of disease through the cervicocephalic arteries rose with it, while the degree of the single worst stenosis did not reliably follow.
Segment-specific analysis added further detail. Significant associations with coronary burden emerged for stenosis in the extracranial vertebral arteries (p = 0.020), the intracranial carotid arteries (p < 0.001), and the middle cerebral arteries (p = 0.011). These findings suggest that disease in particular segments of the head and neck circulation carries information about the state of the coronary tree, with the intracranial carotid segments showing the strongest statistical association in this dataset.
The study also examined symptomatic cerebral infarction among these cardiac patients. A history of symptomatic cerebral infarction was associated with higher coronary artery calcium scores and higher Gensini scores, with both comparisons reaching statistical significance at p < 0.05. This ties the neurological manifestation of atherosclerosis to a heavier coronary burden within the same population of patients presenting with acute coronary syndrome.
The authors frame these results as supporting the concept of systemic atherosclerotic involvement across vascular beds. Because atherosclerosis is a systemic disease affecting multiple vascular beds, the state of one arterial territory can reflect the state of another. Prior studies had demonstrated associations between coronary and cervicocephalic atherosclerosis in cerebrovascular populations, but the relationship in patients presenting with NSTEACS remained incompletely characterized, and it was unclear whether extent or severity of cervicocephalic disease better reflects coronary burden. This study addresses that gap directly in a cardiac population.
The practical implication, according to the study’s conclusions, is that assessing the extent of cervicocephalic disease may complement conventional stenosis-based evaluation by providing additional information on overall atherosclerotic burden. In patients already undergoing CTA for chest pain or acute coronary syndromes, the number of stenotic segments, the presence of bilateral disease, and combined extracranial and intracranial involvement may offer a fuller picture of systemic atherosclerosis than the maximal stenosis grade alone.
As with any cross-sectional study, the findings describe associations at a single point in time in a single center and cannot establish causation or predict outcomes. The study was published as an open-access article on 25 October 2026, and the version shared is a peer-reviewed, accepted manuscript that is citable and carries a permanent DOI, subject to further edits before the final Version of Record. Within those limits, the message is clear: in patients with NSTEACS, the geographic spread of atherosclerosis through the arteries of the head and neck is a strong statistical companion of coronary atherosclerotic burden, and counting affected segments may say more than measuring the tightest narrowing.
