Detection of elevated right atrial pressure using a simple bedside ultrasound measure.
Accurate assessment of right atrial pressure (RAP) often requires invasive measurement. With normal RAP, Valsalva increases right internal jugular vein (RIJV) cross sectional area (CSA) 20% to 30%. With high RAP, when venous compliance is low, we hypothesized that the increase in CSA would be blunted and could be detected non-invasively with bedside ultrasound. ⋯ An increase in RIJV CSA >17% during Valsalva effectively rules out elevated RAP. This simple bedside technique may be useful to assess central venous pressure and reduce the need for invasive pressure measurement.

Multicenter Study Comparative StudyAre quality improvements associated with the Get With the Guidelines-Coronary Artery Disease (GWTG-CAD) program sustained over time? A longitudinal comparison of GWTG-CAD hospitals versus non-GWTG-CAD hospitals.
Previous reports have demonstrated that participation in GWTG-CAD, a national quality initiative of the American Heart Association, is associated with improved guideline adherence for patients hospitalized with CAD. We sought to establish whether these benefits from participation in GWTG-CAD were sustained over time. ⋯ Hospitals participating in GWTG-CAD had modestly superior acute cardiac care and secondary prevention measures performance relative to non-GWTG-CAD. These benefits of GWTG-CAD participation were sustained over time and independent of hospital characteristics.

Comparative StudyTriple antiplatelet therapy reduces ischemic events after drug-eluting stent implantation: Drug-Eluting stenting followed by Cilostazol treatment REduces Adverse Serious cardiac Events (DECREASE registry).
Cilostazol has reduced restenosis and repeat intervention after drug-eluting stent (DES) implantation. However, there is little data regarding impact of cilostazol on cardiac events after DES implantation. Therefore, we assessed the long-term efficacy and safety of cilostazol in patients undergoing successful DES implantation. ⋯ Triple antiplatelet therapy significantly reduced 12-month risks of stent thrombosis and MI after DES implantation compared with dual antiplatelet therapy without increased risk of bleeding complications. The longer duration of triple therapy after DES implantation was associated with the lower risk of stent thrombosis and MI.

Review Comparative StudyPercutaneous coronary intervention or coronary artery bypass surgery for cardiogenic shock and multivessel coronary artery disease?
Despite advances in treatment of cardiogenic shock (CS), the incidence of this serious complication of acute ST-elevation myocardial infarction (STEMI) has stayed relatively constant, and rates of mortality, although somewhat improved in recent decades, remain dauntingly high. Although both percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) are used in patients with CS with multivessel coronary disease, the optimal revascularization strategy in this setting remains unknown. ⋯ Limited data from observational studies in patients with CS and multivessel disease suggest that CABG should be considered a complementary reperfusion strategy to PCI and may be preferred, especially when complete revascularization with PCI is not possible. Our data highlight the need for large randomized trials to further evaluate the relative benefit of PCI versus CABG in patients with multivessel coronary disease and CS using contemporary surgical and percutaneous techniques.

Randomized Controlled Trial Comparative StudySafety and feasibility of early hospital discharge in ST-segment elevation myocardial infarction--a prospective and randomized trial in low-risk primary percutaneous coronary intervention patients (the Safe-Depart Trial).
Patients with ST-segment elevation myocardial infarction (STEMI) have traditionally been hospitalized for 5 to 7 days to monitor for serious complications such as heart failure, arrhythmias, reinfarction, and death. The Zwolle Primary Percutaneous Coronary Intervention (PCI) Index is an externally validated risk score that has been used to identify low-risk STEMI patients who have undergone primary PCI and can safely be discharged from hospital within 72 hours. Previous studies have shown that many low-risk patients remain in hospital significantly longer. ⋯ In low-risk STEMI patients treated with primary or rescue PCI, a strategy of early hospital discharge facilitated by close nursing follow-up is feasible. Although our study did not identify differences in compliance or quality of life between the 2 groups, it did provide a functional study design for a larger trial powered to detect these important clinical end points.
