BACKGROUND AND AIMS: Coronary small vessel disease (CSVD) is often associated with significant percutaneous coronary intervention (PCI) related complications, complex lesions, complex PCI, and poor long-term prognosis. We designed this retrospective study to clarify the characteristics, risk factors, and prognostic analyses of CSVD in Chinese populations.
METHODS: A total of 986 patients who underwent coronary angiography and stent implantation at the First Affiliated Hospital of Zhejiang University School of Medicine were evaluated. Patients were grouped into CSVD or non-small vessel disease (non-CSVD) according to stent diameter. Clinical data, coronary angiography, and long-term follow-up were recorded. Multivariate logistic regression, the Kaplan-Meier method, Log-rank Test, and Cox regression model were used for statistical analysis.
RESULTS: Alcohol consumption (OR = 0.420, 95% CI: 0.299-0.588, P < 0.001) was implicated as a negative CSVD correlation factor. CSVD was more likely to be associated with multi-vessel lesions (79.2% vs. 49.4%, P < 0.001), bifurcation lesions (24.0% vs. 12.4%, P < 0.001), chronic total obstruction lesions (29.5% vs. 9.4%, P < 0.001), and long lesions (55.2% vs. 35.7%, P < 0.001), which reduced the efficacy of revascularization (70.1% vs. 85.1%, P < 0.001). In the follow-ups, cardiac death (2.3% vs. 0.4%, P = 0.008), stroke (1.9% vs. 0.3%, P = 0.007), target lesion revascularization (5.8% vs. 2.9%, P = 0.029), target vessel revascularization (6.8% vs. 3.4%, P = 0.016), and non-target vessel revascularization (7.8% vs. 4.0%, P = 0.012) were all substantially higher in CSVD patients. Troponin I level (OR = 1.008, 95% CI: 1.004-1.012, P < 0.001), complete revascularization (OR = 0.292, 95% CI: 0.160-0.531, P < 0.001), and aspirin administration (OR = 0.041, 95% CI: 0.013-0.131, P < 0.001) were independent predictors of MACE events of all patients.
CONCLUSION: Compared to non-CSVD, CSVD was associated with more complex lesions, had worse revascularization efficacy, and a poorer prognosis.
