Insights
Patients with liver cirrhosis undergoing percutaneous coronary intervention (PCI) face significantly higher risks of in-hospital mortality, gastrointestinal bleeding, stroke, acute kidney injury, and vascular complications compared to those without cirrhosis.
Area of Science:
- Cardiology
- Gastroenterology
- Nephrology
Background:
- Limited data exists on percutaneous coronary intervention (PCI) outcomes in liver cirrhosis patients.
- Liver cirrhosis is a significant comorbidity that may impact cardiovascular procedure outcomes.
Purpose of the Study:
- To systematically review and meta-analyze clinical outcomes of PCI in patients with liver cirrhosis.
- To compare adverse event rates between PCI patients with and without cirrhosis.
Main Methods:
- Comprehensive literature search across PubMed, Embase, Cochrane, and Scopus.
- Meta-analysis using a random-effects model (DerSimonian and Laird) to calculate odds ratios (OR) with 95% confidence intervals (CI).
- Inclusion of 3 studies with data from over 10.7 million patients (28,100 with PCI + Cirrhosis, 10,677,876 with PCI alone).
Main Results:
- Cirrhosis patients undergoing PCI had higher in-hospital mortality (OR 4.78), GI bleeding (OR 1.91), stroke (OR 2.48), acute kidney injury (AKI) (OR 3.66), and vascular complications (OR 1.50).
- Hypertension was the most common comorbidity in the PCI + Cirrhosis group (68.15%).
- Mean age was similar between groups (63.45 years for PCI + Cirrhosis vs. 64.35 years for PCI alone).
Conclusions:
- Liver cirrhosis patients are at substantially increased risk for adverse outcomes and mortality post-PCI.
- These findings highlight the need for careful risk assessment and management in cirrhotic patients undergoing PCI.
Abstract:
There is a paucity of data and minimal literature on outcomes of percutaneous coronary intervention (PCI) among liver cirrhosis patients. Therefore, we conducted a systematic review and meta-analysis to evaluate the clinical outcomes among liver cirrhosis patients post-PCI. We conducted a comprehensive literature search in the PubMed, Embase, Cochrane, and Scopus databases for relevant studies. Effect sizes were pooled using the DerSimonian and Laird random-effects model as an odds ratio (OR) with 95% confidence intervals (CI). A total of 3 studies met the inclusion criteria, providing data from 10,705,976 patients. A total of 28,100 patients were in the PCI + Cirrhosis group and 10,677,876 patients were in the PCI-only group. The mean age of patients with PCI + Cirrhosis and PCI alone was 63.45 and 64.35 years. The most common comorbidity was hypertension among the PCI + Cirrhosis group compared with PCI alone (68.15% vs. 73.6%). Cirrhosis patients post-PCI were had higher rates of in-hospital mortality (OR, 4.78 (95%CI: 3.39-6.75), p < 0.001), GI bleeding (OR, 1.91 (95%CI:1.83-1.99), p < 0.001, I2 = 0%), stroke (OR, 2.48 (95%CI:1.68-3.66), p < 0.001), AKI (OR, 3.66 (95%CI: 2.33-6.02), p < 0.001), and vascular complications (OR, 1.50 (95%CI: 1.13-1.98), p < 0.001) compared with the PCI group without cirrhosis. Patients with cirrhosis are at a high risk for mortality and adverse outcomes post-PCI procedure compared to the PCI-only group of patients.
