“…Also, in our study population, we measured LVEF at 6 months, and some reports have suggested ongoing remodeling also beyond this period [21]. Moreover, we had no data on the extent of stunned but functionally viable myocardium in the infarct zone, as it can be estimated by other imaging studies [22]. Also we did not study the possible influence of other factors such as a better anticoagulant regimen or improvements in PCI procedure such as thrombo-aspiration; these therapeutic innovations might result in a greater portion of viable myocardium and consequently in a greater potential for recovery in LV systolic function.…”

Left ventricular ejection fraction (LVEF) and pulse wave velocity (PWV) are acknowledged as independent risk factors in different high-risk populations. We investigated the effects of arterial stiffness on LV function at 3 and 6 months after acute myocardial infarction. Changes in LVEF were evaluated in 136 consecutive patients who were diagnosed with ST-segment elevation coronary syndrome and treated with primary percutaneous coronary intervention. Doppler guided by 2D ultrasound was used to measure carotid-femoral PWV. According to tertiles of arterial stiffness, a significant correlation between higher PWV and worse recovery in LVEF was found (3 months EF change: 9.9 ± 5.0% vs 5.9 ± 3.4 vs 3.8 ± 1.6; p < 0.001 and 6 months EF change: 18.5 ± 7.0% vs 11.5 ± 5.2 vs 7.3 ± 3.0; p = 0.002). In the multivariate analysis PWV showed the ability to predict the outcome in terms of EF recovery at 3 and 6 months also after any correction for age and other variables (β = -0.566, p < 0.001). Arterial stiffening may result in a less effective recovery of LV function after acute myocardial infarction.

“…There might be interest in combining hybrid imaging from SPECT and MR, although no commercial SPECT/MR machine is sold today. Indeed, an interesting study found that in case of doubtful viability by MR, performing a gated-SPECT could detect viability or ischemia in up to 31 % of the segments with 50–75 % late-gadolinium enhancement [ 33 ]. These initial study questions will certainly also be addressed with existing PET/MR scanners.…”

Cardiac multimodality (hybrid) imaging can be obtained from a variety of techniques, such as nuclear medicine with single photon emission computed tomography (SPECT) and positron emission tomography (PET), or radiology with multislice computed tomography (CT), magnetic resonance (MR) and echography. They are typically combined in a side-by-side or fusion mode in order to provide functional and morphological data to better characterise coronary artery disease, with more proven efficacy than when used separately. The gained information is then used to guide revascularisation procedures. We present an up-to-date comprehensive overview of multimodality imaging already in clinical use, as well as a combination of techniques with promising or developing applications.
