In-Hospital Outcome of Percutaneous Coronary Interventions in Patients with Left Ventricular Systolic Dysfunction

Left ventricular dysfunction is considered a high-risk condition for performing either percutaneous or surgical revascularization. The aim of this study was to evaluate immediate procedural and clinical outcomes and in-hospital complications of percutaneous coronary interventions (PCI) in patients with coronary artery disease (CAD) and ventricular systolic dysfunction.
Four hundred consecutive patients with documented obstructive CAD and left ventricular systolic dysfunction (EF <45%) were selected. Left ventricular ejection fraction was assessed via transthoracic echocardiography at the time of hospitalization. Indications for PCI were made on the basis of clinical and non-invasive studies. The majority of the patients (75%) were males, and their mean age was 55.9±10.7 years. More than half of the patients (56.78%) had multi-vessel disease. Multi-vessel PCI was performed in 51 (12.85%) patients. A total of 397 stents were implanted (0.99 stent/patient).
Technical procedural success was obtained in 96.75% of the patients. Procedural death was not seen. Non-Q wave acute myocardial infarction occurred in 12 (3%) patients, Q-wave AMI in four (1%), emergency coronary artery bypass grafting in six (1.5%), and cardiogenic shock in three (0.75%). Stroke did not occur in any cases. Major bleeding occurred in one (0.25%) patient, and 4.2% of the patients experienced minor bleeding.
In patients with CAD and left ventricular systolic dysfunction, PCI can be performed with a good procedural outcome and acceptable in-hospital complications
