AimEvaluation of the frequency hospital cardiovascular events in groups of patients with stable angina who underwent percutaneous coronary interventions (PCI) with stenting of the arteries before coronary bypass surgery, or who did not have previous myocardial revascularization.Materials And MethodsThe 120 patients with stable angina who underwent routine coronary artery bypass grafting were examined. Group composition: Men 80.8%, age 587.6, duration of coronary heart disease 65.7 years, history of myocardial infarction (MI) 77.5%. Arterial hypertension was present in 92.5%, diabetes mellitus in 12.5% of patients. Multivessel coronary artery disease in 72.5% of patients. 28 (23.4%) patients had previously undergone PCI with stenting of the coronary arteries. The period from PCI to coronary bypass surgery was 2032.6 months. Coronary bypass surgery on-pump was performed in 88.3%, coronary bypass surgery on off-pump in 11.7%. The number of distal anastomoses ranged from 1 to 4.ResultsThere were no differences in clinical and angiographic indicators, pharmacotherapy, and operation characteristics between the groups of patients who were subjected to or did not have PCI before coronary bypass surgery. There were no differences between the analyzed groups of patients in the frequency of cardiac death (0 and 1.1%, p=0.58), non-fatal MI (3.6% and 9.8%, p=0.29), stroke (0 and 1.1%, p=0.58), acute heart failure (11.7% and 34.8%, p=0.06), the number of patients with paroxysms of atrial fibrillation (28.6% and 17.4%, p=0.94), the proportion of patients with resternotomies (3.6% and 3.3%, p=0.94) and gastrointestinal bleeding (3.6% and 4.3%, p=0.86).ConclusionPCI with coronary artery stenting, prior to coronary bypass surgery, does not affect the frequency of post-operative hospital cardiovascular and hemorrhagic complications.
