UNLABELLED The presence of myocardial viability is predictive of improvement in regional left ventricular (LV) function after revascularization. Studies on predicting improvement in global LV function are scarce, and the amount of viable myocardium needed for improvement in LV ejection fraction (LVEF) after revascularization is unknown. Moreover, whether the presence of viability is associated ...
BACKGROUND Surgical coronary revascularization with cardiopulmonary bypass and cardioplegia has been associated with reperfusion injury. The serine protease inhibitor aprotinin has been suggested to reduce reperfusion injury, yet a clinically relevant study examining regional ischemia under conditions of cardiopulmonary bypass and cardioplegia has not been performed. METHODS Pigs were subject...
Introduction: Differentiating between ischemic cardiomyopathy (ICM) and idiopathic dilated cardiomyopathy (IDCM) is important as coronary revascularization can improve prognosis in the ischemic subgroup. Due to inherent problems of coronary angiography in patients with depressed ejection fraction (EF) introducing a noninvasive tool to diagnose those who will benefit from angiography seems...
Soon after the introduction of coronary artery bypass surgery, the completeness of revascularization became a matter of concern. Several early surgical studies confirmed the belief that better clinical outcomes were obtained when each and every angiographically visible stenosis was bypassed by a distal anastomosis.1,2 Similarly, among patients with multivessel disease treated with percutaneous ...

BACKGROUND Limited information is available on long-term outcomes for patients with unprotected left main coronary artery disease who received drug-eluting stents (DES). METHODS AND RESULTS In the multicenter registry evaluating outcomes among patients with unprotected left main coronary artery stenosis undergoing stenting with either bare metal stents (BMS) or DES, 1217 consecutive patients ...
BACKGROUND Second-generation drug-eluting stents (DESs) are known to have better safety and clinical outcomes compared with the first-generation DESs. We compared the clinical results of off-pump coronary artery bypass grafting (OPCAB) with percutaneous coronary intervention (PCI) using second-generation DESs. METHODS The study enrolled 1,821 patients with triple-vessel or left main coronary ...
