Target vessel revascularization following percutaneous coronary intervention. A 10-year report from the Danish Percutaneous Transluminal Coronary Angioplasty Registry.
OBJECTIVE
To present the rate of target vessel revascularization (TVR) in a consecutive and unselected national population over 10 years.


METHODS
From 1989 to 1998 all percutaneous coronary interventions (PCIs) performed in Denmark were recorded in the Danish PTCA Registry.


RESULTS
From 1989 to 1998 the annual rate of PCI rose from 46 to 753 per million inhabitants. From 1995 to 1998 TVR with PCI or coronary artery bypass grafting (CABG) within 9 months from the index PCI decreased significantly (p < 0.001) from 21.2% in 1995 (CABG 8.6% vs PCI 12.6%) to 11.7% in 1998 (CABG 4.3% vs PCI 7.4%). Independent predictors for TVR were: coronary stenting (OR 0.60; 95% CI 0.52-0.69, p < 0.001), primary success rate (OR 0.69; 95% CI 0.53-0.89, p < 0.005), pre-PCI stenosis severity (OR 1.01; 95% CI 1.00-1.01, p = 0.03), left anterior descending coronary artery (OR 2.35; 95% CI 1.73-3.19, p < 0.001), right coronary artery (OR 1.61; 95% CI 1.17-2.20, p = 0.003), sapheneous vein graft (OR 2.03; 95% CI 1.13-3.63, p = 0.017) and age (OR 0.99; 95% CI 0.98-1.00, p = 0.002).


CONCLUSIONS
Coronary stenting, primary success rate, pre-PCI stenosis severity, age and treated vessel were independent predictors for TVR.
