Coronary small vessel disease was associated with more complex lesions, worse revascularization efficacy, and a poorer prognosis for MACE events compared to non-CSVD (P<0.001).

Does coronary small vessel disease (CSVD) worsen long-term prognosis compared to non-CSVD in patients undergoing stent implantation?
Coronary small vessel disease is associated with more complex lesions and poorer long-term prognosis following stent implantation compared to non-small vessel disease.
p-value: p=<0.001
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: < 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.
Chen et al. (Thu,) conducted a cohort in Coronary small vessel disease (n=986). Coronary small vessel disease (CSVD) vs. Non-small vessel disease (non-CSVD) was evaluated on MACE events (p=<0.001). Coronary small vessel disease was associated with more complex lesions, worse revascularization efficacy, and a poorer prognosis for MACE events compared to non-CSVD (P<0.001).
