Symptom-to-balloon time and myocardial blush grade are predictors of left ventricular remodelling after successful primary percutaneous coronary intervention.
Cardiovascular Journal of Africa 2017 May
INTRODUCTION: In patients with ST-segment elevation myocardial infarction (STEMI), successful primary percutaneous coronary intervention (PCI) was found to be useful in earlier restoration of TIMI flow 3. However, the incidence of left ventricular (LV) dilatation and remodelling after successful primary PCI is still high. We aimed to determine the independent predictors of LV remodelling after successful primary PCI for patients with first STEMI.
METHODS: We included 232 STEMI patients treated with primary PCI. Echocardiography was done on the day of PCI and after six months. LV remodelling was defined as ≥ 20% increase in the six-month left ventricular end-diastolic volume (LVEDV).
RESULTS: In patients with remodelling, symptom-to-door and symptom-to-balloon times were significantly longer (p < 0.00001 for each), initial ejection fraction (EF) was significantly lower (p = 0.044), six-month LVEDV, left ventricular end-systolic volume (LVESV) and LVEDV increase were significantly higher, and EF was significantly lower (p < 0.00001 for each). Mean myocardial blush grade (MBG) was significantly lower in patients with remodelling (p < 0.00001). There was a significant positive correlation between LVEDV increase and both symptom-to-balloon time (r = 0.603, p < 0.00001) and symptom-to-door time (r = 0.564, p < 0.00001), and a significant negative correlation between LVEDV increase and MBG (r = -0.447, p < 0.00001). Logistic regression showed that the independent predictors of LV remodelling were symptom-to-balloon time (p = 0.00068), symptom to door time (p = 0.0013) and MBG (p = 0.0057).
CONCLUSION: Symptom-to-door time, symptom-to-balloon time and MBG were the only significant predictors of LV remodelling.
