Prognosis of Percutaneous Intervention of a Left Main Coronary Artery Stenosis Without the Use of Intravascular Imaging

Abstract

ObjectivesThe aim of this study was to assess the prognosis in patients with left main coronary artery stenosis one year after percutaneous coronary intervention (PCI).MethodsOur study included 40 patients who underwent PCI for left main coronary artery stenosis without the use of intravascular ultrasound (IVUS). Patients were followed for a year, and the prognostic effect of PCI on a composite end-point of revascularization, new myocardial infarction, cardiac death, and on all-cause mortality was assessed in multivariable Cox analysis.ResultsThe multivariable analysis showed a good prognosis in patients receiving PCI with a total event rate of 7.5%. The independent predictors for major adverse cardiac events (MACE) were diabetes (p = 0.02). Other prognostic factors included in the model were gender, age, smoking, body mass index (BMI), hypertension, the complexity of the vessel, and ejection fraction.ConclusionPCI for left main coronary artery stenosis without the use of IVUS has a good prognosis after one year of clinical follow-up.

Coronary Artery Bypass Grafting Versus Percutaneous Coronary Intervention in Patients with Distal Left Main Coronary Disease

“…We found an increased risk of MACCE in patients with LMCA disease in older age, diabetics, and with a history of MI, low EF, and high SYNTAX score. In a study by Mahmoud and colleagues, they found that diabetes, smoking, body mass index, hypertension, the complexity of the vessel, and ejection fraction were predictors of MACCE after PCI for LMCA disease [17] . The SYNTAX score was a predictor of mortality and MACCE in patients with PCI for LMCA disease [18] .…”
