Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialThe Asymptomatic Cardiac Ischemia Pilot (ACIP) study: design of a randomized clinical trial, baseline data and implications for a long-term outcome trial.
The primary objectives of the Asymptomatic Cardiac Ischemia Pilot were 1) to compare the 12-week efficacy of three treatment strategies to suppress cardiac ischemia, and 2) to assess the feasibility of a prognosis trial in patients with asymptomatic cardiac ischemia. ⋯ Design and baseline data for a pilot study of ischemia treatment strategies are described.

Randomized Controlled Trial Comparative Study Clinical TrialActive compression-decompression resuscitation: effect on resuscitation success after in-hospital cardiac arrest.
The purpose of this study was to test the hypothesis that active compression-decompression would improve resuscitation success in human subjects after cardiac arrest. ⋯ Active compression-decompression cardiopulmonary resuscitation improves return of spontaneous circulation and 24-h survival after in-hospital cardiac arrest. Active compression-decompression cardiopulmonary resuscitation appears to be a beneficial adjunct to standard manual cardiopulmonary resuscitation.

Comparative StudyAccurate measurement of the transmitral gradient in patients with mitral stenosis: a simultaneous catheterization and Doppler echocardiographic study.
This study compared the accuracy of Doppler echocardiography with that of conventional cardiac catheterization in the measurement of transmitral gradients in patients with mitral stenosis. ⋯ Compared with the transmitral gradient obtained by direct measurement of left atrial and left ventricular pressures, the Doppler-derived gradient is more accurate than that obtained by conventional cardiac catheterization and should be considered the reference standard.

Comparative StudyPrognostic value of Doppler transmitral flow patterns in patients with congestive heart failure.
This study was designed to determine whether Doppler echocardiographic transmitral flow patterns can predict cardiac mortality in patients with congestive heart failure. ⋯ In patients with congestive heart failure, a restrictive transmitral flow pattern, female gender and advanced functional class are predictive of higher cardiac mortality. The restrictive transmitral flow pattern by Doppler echocardiography is the single best clinical predictor for cardiac death in patients with congestive heart failure.
