Long-term outcome of left main coronary artery stenting using the provisional stenting technique and the impact of cardiorenal-metabolic syndrome on clinical results

The article presents the results of a prospective study involving 178 patients with coronary artery disease and significant left main coronary artery (LMCA) stenosis. Long-term outcomes after percutaneous coronary intervention (PCI) using the provisional stenting technique were compared with surgical revascularization, in patients with and without cardiorenal-metabolic syndrome (CRMS). It was found that CRMS significantly worsens the prognosis after PCI, while coronary artery bypass grafting neutralizes this negative impact. The findings emphasize the importance of assessing CRMS status when selecting a revascularization strategy in patients with LMCA lesions.
