Abstract
BACKGROUND
Revascularisation strategy in patients with multi-vessel coronary disease and acute myocardial infarction (AMI) remains challenging. One of the potential treatment options is complete percutaneous revascularisation during index hospitalisation. This strategy could positively influence left ventricle ejection fraction (LVEF).
AIM
To investigate the long-term changes in LVEF and clinical outcome among patients with AMI after complete coronary revascularisation (CCR).
METHODS
Records of 171 patients with a diagnosis of AMI and multi-vessel coronary artery disease (CAD) on index angiography, in whom CCR was performed as a staged procedure during initial hospitalisation, were analysed. Clinical data were collected from in-hospital medical records and discharge letters. Cardiac ultrasound (CU), with particular assessment of LVEF, was performed one day before discharge. Follow-up (FU) CU was collected from the out-patient department at least six months ± one week after discharge. Follow-up data, including major adverse cardiac events (MACE), were collected during follow-up visits by telephone. Depending on the LVEF change during the follow-up period, patients were divided into two groups. Patients with a decrease in the LVEF (D-LVEF group) were compared with patients with no changes (preserved) or improvement regarding LVEF (P/I-LVEF).
RESULTS
The median duration of the follow-up was 19 months (14-24 months). The median change in LVEF during observation was -5.0p% (IQR (-7.0)-(-2.75p.%)) in the D-LVEF group and +4.0% (IQR 1.0-5.0p%) in the P/I-LVEF group. Among patients in the P/I-LVEF group, there was a sub-group of patients with no change in LVEF (28 patients), and one demonstrating improvement in LVEF (104 patients). In the subgroup of patients with improved LVEF, the median change in LVEF was 4.5p% (IQR 2-6.25p%). Among patients with decreasing LVEF, there was a significantly higher risk of MACE (15 vs. 2.3%, p = 0.031), especially non-fatal AMI (10 vs. 0%, p = 0.017). We found the following among predictors concerning increased risk of MACE occurrence: urgent PCI (p = 0.004), hospitalisations regardless of cause (p = 0.028), EF worsening (p = 0.025), fasting glucose serum concentration (p = 0.024) and fasting triglyceride serum concentration (p = 0.027).
CONCLUSIONS
Complete revascularisation (CR) at baseline (one stage) in patients with AMI and multi-vessel disease is associated with LVEF improvement and MACE rate reduction. Patients with worse LVEF have poor clinical outcome and a higher rate of MACE.
