The characteristic of acute coronary syndromes of patients with multivessel coronary artery disease in centers with and without cardiac surgery on-site.

BACKGROUND

Multivessel disease (MVD) is diagnosed in a fair number of patients with acute coronary syndrome (ACS). There are 36 cardiac-surgery (CS) centres and 157 catheterization laboratories dedicated to treat ACS in Poland. The aim of the study was to analyze MVD patient outcomes presented with ACS in centers with or without CS on-site.

METHODS

The present study is a retrospective analysis (2017-2020) of MVD ACS patients (n = 4618) outcomes between those treated in centers with CS on site (n = 595) and those without CS (n = 4023).

RESULTS

Patients in CS centers had a higher prevalence of renal failure (13.3% vs. 8.8%, p ≤ 0.001) and a more frequent history of coronary angioplasty - percutaneous coronary intervention (18.9% vs. 14.4%, p = 0.005). During the coronary angiography a femoral artery access was more often used in CS center patients (47.1% vs. 15.2%, p < 0.001). Percutaneous coronary intervention of MVD was more often performed in CS centers (74.6% vs. 71.0%, p = 0.054). In-hospital death (7.6% vs. 4.6%, p = 0.002), reinfarction (1.1% vs. 0.1%, p < 0.001), hemorrhagic complications (6.4% vs. 1.6%, p < 0.001), recurrent target vessel revascularization (1.8% vs. 0.4%, p ≤ 0.001) and pulmonary edema (3.7% vs. 1.5%, p < 0.001) occurred more often in CS centers.

CONCLUSIONS

The safety of ACS treatment in MVD patients in centers without CS on site is non-inferior to their treatment in centers with CS on site. Interestingly, there were more in-hospital adverse events observed in ACS MVD patients treated in centers with CS.
