Randomized Controlled Trial Multicenter Study Clinical TrialFunctional status and quality of life after emergency revascularization for cardiogenic shock complicating acute myocardial infarction.
Our goal was to describe the functional status of cardiogenic shock survivors, identify the correlates of cardiogenic shock, and compare global quality of life and functional status of patients randomly assigned to treatment with emergency revascularization (ERV) versus initial medical stabilization (IMS). ⋯ Although one-year mortality after ERV is still high (54%), most survivors have good functional status. The ERV patients have a lower rate of deterioration than IMS patients. The level of recovery for shock patients undergoing ERV is similar to that of historical controls not in cardiogenic shock undergoing elective revascularization.

Randomized Controlled Trial Clinical TrialManual thrombus-aspiration improves myocardial reperfusion: the randomized evaluation of the effect of mechanical reduction of distal embolization by thrombus-aspiration in primary and rescue angioplasty (REMEDIA) trial.
The aim of this study was to evaluate the use of a new manual thrombus-aspirating device in unselected patients with ST-segment elevation acute myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). ⋯ This prospective randomized study shows that manual thrombus-aspiration in unselected patients with STEMI undergoing primary or rescue PCI is clinically feasible and results in better angiographic and ECG myocardial reperfusion rates compared with those achieved by standard PCI.

Multicenter StudyFunctional assessment of mitral regurgitation by transthoracic echocardiography using standardized imaging planes diagnostic accuracy and outcome implications.
We sought to assess the value of transthoracic echocardiography (TTE) using standardized imaging planes for the functional analysis of mitral regurgitation (MR) as well as for postoperative outcome implications. ⋯ In experienced hands, functional assessment of MR by TTE can predict accurately valve repairability and has a strong influence on postoperative outcome. Thus, in most cases preoperative TEE is not mandatory, provided intraoperative TEE is performed.

Randomized Controlled Trial Comparative Study Clinical TrialEffects of aggressive versus conventional lipid-lowering therapy by simvastatin on human atherosclerotic lesions: a prospective, randomized, double-blind trial with high-resolution magnetic resonance imaging.
This study sought to compare the effects of aggressive and conventional lipid lowering by two different dosages of the same statin on early human atherosclerotic lesions using serial noninvasive magnetic resonance imaging (MRI). ⋯ Effective and protracted lipid-lowering therapy with simvastatin is associated with a significant regression of atherosclerotic lesions. No difference in vessel wall changes was seen between high and conventional doses of simvastatin. Changes in vessel wall parameters are more related to LDL-C reduction rather than to the dose of statin.
