Randomized Controlled Trial Multicenter Study Comparative Study
Optimal duration of dual antiplatelet therapy after second-generation drug-eluting stent implantation in patients with diabetes: The SECURITY (Second-Generation Drug-Eluting Stent Implantation Followed By Six- Versus Twelve-Month Dual Antiplatelet Therapy)-diabetes substudy.
The randomized SECURITY (Second-Generation Drug-Eluting Stent Implantation Followed by Six- Versus Twelve-Month Dual Antiplatelet Therapy) trial showed the non-inferiority of 6 vs. 12-month DAPT after percutaneous coronary intervention (PCI) with second-generation DES in a low-risk population. Nevertheless, diabetes mellitus (DM) remained a major predictor of adverse cardiovascular events. We aimed to assess the interaction between DAPT duration and outcome in DM patients. ⋯ In diabetic patients treated by second-generation DES PCI, we failed to find any additional benefit of prolonging DAPT beyond 6months, regardless of insulin-requiring status.

The impact of left ventricular ejection fraction on fractional flow reserve: Insights from the FAME (Fractional flow reserve versus Angiography for Multivessel Evaluation) trial.
Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) significantly improves outcomes compared with angio-guided PCI in patients with multivessel coronary artery disease. However, there is a theoretical concern that in patients with reduced left ventricular ejection fraction (EF) FFR may be less accurate and FFR-guided PCI less beneficial. ⋯ Reduced EF has no influence on the FFR value unless the stenosis is very tight, in which case a theoretically explainable, but clinically irrelevant overestimation might occur. As a result, FFR-guided PCI remains beneficial regardless of EF.

Comparison of combination therapy of high-dose oral N-acetylcysteine and intravenous sodium bicarbonate hydration with individual therapies in the reduction of Contrast-induced Nephropathy during Cardiac Catheterisation and Percutaneous Coronary Intervention (CONTRAST): A multi-centre, randomised, controlled trial.
N-acetylcysteine (NAC) and sodium bicarbonate (SOB) therapies may prevent contrast-induced nephropathy (CIN). However, the efficacy of using combination over individual therapies was not established, and there was no large randomised study comparing abbreviated SOB therapy with conventional sustained saline pre-hydration with oral NAC. ⋯ The combination regimen was not superior to individual regimens in preventing CIN in patients with baseline renal impairment. There was a trend suggesting that the 12-hour sustained sodium chloride pre-hydration regimen was more protective than the 1-hour abbreviated SOB regimen.

Efficacy of electroacupuncture pretreatment for myocardial injury in patients undergoing percutaneous coronary intervention: A randomized clinical trial with a 2-year follow-up.
Electroacupuncture pretreatment (EAP) safely protects the heart from ischemic injury, however, the efficacy of EAP for periprocedural myocardial injury after percutaneous coronary intervention (PCI) remains unclear. Our aim was to investigate whether EAP prior to PCI reduces post-PCI myocardial injury in patients with coronary artery disease (CAD). 388 patients (≥ 18 years old) with CAD, undergoing elective PCI were enrolled and randomized, out of those 204 went through the whole trial. EAP was conducted by 30-minute electrical stimulation through 4 electrodes attached to the Antiguan (PC6) and Ximen (PC4) acupoints in the forearm bilaterally 1-2h prior to PCI. ⋯ The MACCE rate was significantly decreased in the EAP group at 24 month follow-up compared to the control group (P=0.0157). Moreover, multivariate logistic regression analysis showed that EAP was associated with decreased likelihood of MACCE (odds ratio 0.327, 95% CI 0.140-0.767, P=0.010). EAP prior to PCI significantly reduced cTnI release and protected patients with CAD from subsequent myocardial injury after PCI procedure.

Early neurologically-focused follow-up after cardiac arrest improves quality of life at one year: A randomised controlled trial.
Survivors of a cardiac arrest frequently have cognitive and emotional problems and their quality of life is at risk. We developed a brief nursing intervention to detect cognitive and emotional problems, provide information and support, promote self-management, and refer them to specialised care if necessary. This study examined its effectiveness. ⋯ The outcomes of cardiac arrest survivors can be improved by an intervention focused on detecting and managing the cognitive and emotional consequences of a cardiac arrest.
