The effect of the type of left ventricular hypertrophy in patients presenting with an acute coronary syndrome (ACS) on long-term outcomes is ill-defined. The purpose of this study was to investigate the prognostic effect of concentric (CH) or eccentric hypertrophy (EH) on adverse outcomes in patients presenting with ACS undergoing percutaneous coronary intervention (PCI).

Material and methods:
We analyzed 1-year follow-up data from a single-institution, retrospective, observational study that enrolled 1,153 patients who presented with ACS and were treated with PCI, for whom echocardiographic data were available.

Normal geometry was observed in 718 (62.3%) patients, while 27.2% had CH and 10.5% had EH. The primary endpoint of all-cause death (n = 90, 7.8%) occurred in 6.4%, 8.0%, and 14.9% of patients with no, concentric, or eccentric hypertrophy, respectively (p = 0.005). Major adverse cardiac events (MACE – all-cause death, non-fatal myocardial infarction or stroke or hospitalization for bleeding) occurred in 13.9%, 17.8%, 30.6%, respectively (p < 0.001). Age (HR per year = 1.04 (1.02, 1.05), p < 0.001), female gender (HR = 1.56 (1.12, 2.16), p = 0.008), diabetes (HR = 1.49 (1.07, 2.06), p = 0.02), eccentric hypertrophy (HR = 1.58 (1.006, 2.47), p = 0.047), peak troponin I (HR per 1 ng/ml = 1.004 (1.001, 1.006), p = 0.004) and left ventricular ejection fraction < 50% (HR = 1.57 (1.12, 2.20), p < 0.008) were significant predictors of MACE.

The presence of eccentric hypertrophy in ACS patients undergoing PCI is an independent predictor of adverse outcomes at 1 year.
