Quality improvement in the door-to-balloon times for ST-elevation myocardial infarction patients presenting without chest pain.
To assess a quality improvement initiative aimed at minimizing door-to-balloon (DTB) times for ST-elevation myocardial infarction (STEMI) patients presenting without chest pain. ⋯ A simple modification of emergency room ECG triage protocol, which expands indications for rapid ECG performance, was successful in improving rapid reperfusion for patients with STEMI presenting without chest pain.

Thrombus aspiration alone during primary percutanous coronary intervention as definitive treatment in acute ST-elevation myocardial infarction.
In some patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutanous coronary intervention (pPCI) with thrombus aspiration, residual stenosis after thrombus aspiration is non-significant and additional balloon dilatation or stent placement may be unnecessary. We investigated the angiographic, procedural, and clinical outcomes of these patients in our single center pPCI-database. In addition, to gain insight in the pathological mechanisms of coronary thrombosis in these patients, we established the histopathological characteristics and age of the aspirated material. ⋯ In selected STEMI patients undergoing pPCI, thrombus aspiration alone is feasible and safe on the short-term and there appears to be no high risk of recurrent ischemic events during follow-up. Our results suggest that additional balloon inflation or stent implantation may be unnecessary in selected patients, when there is no significant residual stenosis after thrombus aspiration.

Comparative StudyEffect of invasive strategy on different genders of Chinese patients with non-ST-elevation myocardial infarction.
The aim of this study was to determine the impact of in-hospital revascularization on different genders and to compare the gender difference in short- and long-term prognosis of Chinese patients with non-ST-elevation myocardial infarction (NSTEMI). ⋯ In Asian ethnic patients with NSTEMI, the in-hospital and long-term prognosis were similar between men and women. In-hospital revascularization has a benefit in men and high-risk women for reducing the all-cause death at 1 and 3 years. Our data provide evidence supporting the guideline recommendation for an invasive strategy in high-risk women.

Randomized Controlled Trial Multicenter Study Comparative StudyPrevention of contrast-induced acute kidney injury in patients with stable chronic renal disease undergoing elective percutaneous coronary and peripheral interventions: randomized comparison of two preventive strategies.
We compared use of intravenous (IV) normal saline (NS) to sodium bicarbonate (NaHCO(3)) with or without oral N-acetylcysteine (NAC) for prevention of contrast-induced acute kidney injury (CI-AKI). ⋯ Incidence of CI-AKI was no different in the NaHCO(3) group compared to NS group, and NAC did not reduce CI-AKI in the two study arms.
