Insights
Patients with chronic kidney disease (CKD) exhibit more vulnerable coronary plaques, characterized by larger lipid content and increased calcification and disruption. Lower estimated glomerular filtration rate is a key risk factor for these concerning plaque characteristics.
Area of Science:
- Cardiology
- Nephrology
- Vascular Biology
Background:
- Chronic kidney disease (CKD) is a known risk factor for atherosclerosis and cardiovascular disease.
- Understanding coronary plaque characteristics in CKD patients is crucial for risk stratification.
Purpose of the Study:
- To compare coronary plaque characteristics between patients with and without CKD using optical coherence tomography (OCT).
Main Methods:
- Analysis of 463 nonculprit coronary plaques from 287 patients in the MGH OCT registry.
- CKD defined as estimated glomerular filtration rate <60 mL/min per 1.73 m².
- Comparison of plaque features including lipid index, fibrous cap thickness, calcification, cholesterol crystals, and plaque disruption between CKD and non-CKD groups.
Main Results:
- CKD plaques showed a significantly larger lipid index compared to non-CKD plaques (1716.1±1116.2 mm° vs. 1248.4±782.8 mm°, P=0.003).
- Higher prevalence of calcification (50.8% vs. 34.8%, P=0.041), cholesterol crystals (23.0% vs. 11.2%, P=0.048), and plaque disruption (13.1% vs. 5.5%, P=0.049) were observed in CKD patients.
- Lower estimated glomerular filtration rate and diabetes mellitus were independent predictors of a larger lipid index.
Conclusions:
- CKD patients present with more complex coronary atherosclerotic plaques, including larger lipid pools and increased plaque instability markers.
- Lower estimated glomerular filtration rate is an independent risk factor associated with adverse coronary plaque morphology in CKD.
Background:
Chronic kidney disease (CKD) promotes the development of atherosclerosis and increases the risk of cardiovascular disease. The aim of the present study was to compare the coronary plaque characteristics of patients with and without CKD using optical coherence tomography.
Methods And Results:
We identified 463 nonculprit plaques from 287 patients from the Massachusetts General Hospital (MGH) optical coherence tomography registry. CKD was defined as estimated glomerular filtration rate <60 mL/min per 1.73 m(2). A total of 402 plaques (250 patients) were in the non-CKD group and 61 plaques (37 patients) were in the CKD group. Compared with non-CKD plaques, plaques with CKD had a larger lipid index (mean lipid arc×lipid length, 1248.4±782.8 mm° [non-CKD] versus 1716.1±1116.2 mm° [CKD]; P=0.003). Fibrous cap thickness was not significantly different between the groups. Calcification (34.8% [non-CKD] versus 50.8% [CKD]; P=0.041), cholesterol crystals (11.2% [non-CKD] versus 23.0% [CKD]; P=0.048), and plaque disruption (5.5% [non-CKD] versus 13.1% [CKD]; P=0.049) were more frequently observed in the CKD group. In the multivariate linear regression model, a lower estimated glomerular filtration rate and diabetes mellitus were independent risk factors for a larger lipid index.
Conclusions:
Compared with non-CKD patients, the patients with CKD had a larger lipid index with a higher prevalence of calcium, cholesterol crystals, and plaque disruption. The multivariate linear regression model demonstrated that a lower estimated glomerular filtration rate was an independent risk factor for a larger lipid index.
