Insights
Hepatitis C virus (HCV) infection did not significantly impact major adverse cardiovascular events or in-stent restenosis after percutaneous coronary intervention (PCI) in a 1-year follow-up study. This finding suggests HCV seropositivity is not a risk factor for PCI outcomes.
Area of Science:
- Cardiology
- Infectious Diseases
- Vascular Medicine
Background:
- Hepatitis C virus (HCV) infection is increasingly linked to atherosclerosis and coronary artery disease (CAD).
- Cardiovascular risk factors like diabetes and dyslipidemia may influence outcomes after percutaneous coronary intervention (PCI).
- The potential impact of HCV on PCI outcomes warrants investigation.
Purpose of the Study:
- To investigate the impact of Hepatitis C virus (HCV) seropositivity on outcomes following percutaneous coronary intervention (PCI).
Main Methods:
- A multi-center prospective cohort study involving 400 patients undergoing elective PCI with drug-eluting stents.
- Patients were divided into two groups: 200 HCV seropositive (untreated) and 200 HCV seronegative.
- One-year follow-up assessed major adverse cardiovascular events (MACEs) and clinical in-stent restenosis.
Main Results:
- HCV seropositivity did not show a higher hazard for MACEs (adjusted HR 0.74; p=0.302) or clinical in-stent restenosis (adjusted HR 1.70; p=0.28) after 12 months.
- Individual cardiovascular outcomes, including target lesion revascularization, myocardial infarction, stroke, stent thrombosis, bleeding, CABG, and cardiac/non-cardiac death, were not significantly different.
- Multivariate Cox hazard regression analysis adjusted for confounding factors.
Conclusions:
- HCV seropositivity was found to have no significant impact on MACEs, specific cardiovascular outcomes, or clinical in-stent restenosis within one year post-PCI.
- The study suggests that HCV status does not adversely affect short-term outcomes after PCI.
Background:
Hepatitis C virus (HCV) infection is progressively recognized as a potential atherogenic condition that is associated with coronary artery disease (CAD). Factors that affect the cardiovascular system as diabetes mellitus and dyslipidemia also may affect the outcomes following PCI. So, HCV infection may have an impact on the outcomes following PCI. We aimed to investigate the impact of HCV seropositivity on the outcomes following percutaneous coronary intervention (PCI).
Results:
We conducted a multi-center prospective cohort study on 400 patients candidate for elective PCI using drug-eluting stents; 200 patients were HCV seropositive and did not received antiviral treatment, and 200 patients were HCV seronegative. The patients were followed up for 1 year for the development of major adverse cardiovascular events (MACEs) and clinical in-stent restenosis. Multivariate Cox hazard regression analyses for MACEs and clinical in-stent restenosis at 12 months after adjustment for confounding factors showed that HCV seropositivity did not present a higher hazard upon MACEs (adjusted hazard ratio (HR) 0.74; 95% CI 0.41-1.32; p value 0.302), the individual cardiovascular outcomes (target lesion revascularization (TLR), target vessel revascularization (TVR), myocardial infarction (MI), cerebrovascular stroke (CVS), stent thrombosis, major bleeding, coronary artery bypass graft (CABG), cardiac death, and non-cardiac death), or the incidence of clinical in-stent restenosis (adjusted HR was 1.70; 95% CI 0.64-4.51; p value 0.28) compared to seronegative patients.
Conclusion:
HCV seropositivity had no impact on MACEs, individual cardiovascular outcomes, or clinical in-stent restenosis following PCI for a 1 year follow-up period.
