The European guidelines recommend revascularization within 24 hours in high-risk patients with No ST segment elevation myocardial infarction. It is unclear whether these patients would benefit from an immediate strategy. This randomized, open, and controlled study included 250 patients with suspected Non ST segment elevation myocardial infarction. Patients were randomized to early coronary angiography or<a href="https://solaci.org/en/2015/06/24/nonstemi-superiority-of-early-angioplasty-in-non-st-elevation-myocardial-infarction/" title="Read more" >...</a>

This is an observational, prospective, multicenter study using optical coherence tomography (OCT) and measurement of fractional flow reserve (FFR) before and after angioplasty. Inpatient following up was set at one month, six months, and one year. Before performing the OCT, the planned strategy was recorded and surgeons were free to change the strategy. The strategy<a href="https://solaci.org/en/2015/06/24/ilumien-i-results-of-the-angioplasty-indicated-by-ffr-and-controlled-by-oct/" title="Read more" >...</a>

This multicenter, prospective, randomized controlled study was designed to evaluate the noninferiority of guided angioplasty by optical frequency domain (OFDI) compared to IVUS. 800 elective patients randomized 1: 1 were included. The diameter of the stent in the IVUS group was higher than in the OFDI group (p = 0.03). Post implant angiography showed a<a href="https://solaci.org/en/2015/06/24/opinion-optical-frequency-domain-versus-ivus-to-guide-angioplasty/" title="Read more" >...</a>

In patients undergoing ST segment elevation myocardial infarction (STEMI) who received primary angioplasty, the strategy of manual thromboaspiration routine does not reduce the risk of cardiovascular death, recurrent infarction, or cardiogenic shock within 180 days compared with standard primary angioplasty with thromboaspiration only if necessary.

This observational registry compared the results of myocardial revascularization with angioplasty performed using everolimus-eluting stents in patients with multivessel. The primary endpoint of the study was mortality from any cause. Side end points were infarction, stroke, and revascularization. Propensity score was used to compare populations. Between 34819 patients were eligible 9223 patients in each group<a href="https://solaci.org/en/2015/06/24/best-similar-mortality-among-angioplasty-with-des-everolimus-and-surgery/" title="Read more" >...</a>

The aim of this study was to compare the usefulness of primary angioplasty only to culprit vessel versus complete revascularization guided by fractional flow reserve (FFR) in patients admitted pursuing an acute myocardial infarction with ST-segment elevation and have multiple injuries vessels. After a successful primary angioplasty to culprit artery, patients were randomized 1:1 to<a href="https://solaci.org/en/2015/06/24/danami3-primary-angioplasty-to-culprit-vessel-versus-multivessel-guided-by-ffr/" title="Read more" >...</a>

Prospective, multicenter, randomized, double-blind study evaluated intravenous infusion of TRO40303 versus placebo administered immediately before balloon dilation of the culprit artery during primary angioplasty. Infarct size was evaluated using the CK Mb levels and troponin together with magnetic resonance imaging. 163 patients were included; no significant differences were observed in the area under the curve<a href="https://solaci.org/en/2015/06/24/mitocare-tro40303-intravenous-infusion-in-the-context-of-primary-angioplasty/" title="Read more" >...</a>

This multicenter, prospective, randomized trial compared the Excimer laser atherectomy (Excimer Laser Atherectomy = ELA, Spectranetics, Inc.) with a balloon angioplasty in patients with in-stent restenosis in the superficial femoral artery. The injury was greater than 4 cm and the reference vessel diameter 5 to 7 mm. The mean lesion length was 19 cm, and<a href="https://solaci.org/en/2015/06/24/excite-isr-excimer-laser-versus-balloon-angioplasty-for-stent-restenosis-of-the-superficial-femoral/" title="Read more" >...</a>
