OBJECTIVE As there are few reports on the clinical results of off-pump coronary artery bypass (OPCAB) in patients with poor left ventricular (LV) function, the safety and efficacy of OPCAB surgery in such patients remains unclear. METHODS From January 2002 to May 2007, a total of 519 consecutive patients underwent isolated myocardial revascularization via(More)
BACKGROUND The purpose of the present study was to investigate the association between preoperative heart rate variability and atrial fibrillation after off-pump coronary artery bypass graft surgery. METHODS Of 524 consecutive patients undergoing isolated coronary artery bypass surgery, 390 were retrospectively analyzed after excluding the following 134(More)
BACKGROUND The purpose of the present study was to assess the preventive effect of preoperative statin treatment on atrial fibrillation (AF) after elective isolated off-pump coronary artery bypass grafting (off-pump CABG) in propensity score-matched Japanese patients. METHODS AND RESULTS Among 770 consecutive patients undergoing isolated CABG by the same(More)
BACKGROUND We report our experience of cardiac surgery with concomitant pulmonary resection, based on analysis of the results. METHODS Eleven patients (1 woman, 10 men) underwent cardiac surgery simultaneously with pulmonary resection; ten of them through median sternotomy. The cancer pathology consisted of non-small cell carcinoma (n = 10), and benign(More)
OBJECTIVE Diabetes mellitus has been recognized as a risk factor for mortality and morbidity after coronary bypass grafting, but a significant association between diabetes mellitus and postoperative atrial fibrillation (AF) has not been found. Although a recent study demonstrated a potential link between preoperative hemoglobin A1c level and risk of(More)
BACKGROUND Left ventricular assist devices (LVAD) are increasingly used for heart failure (CHF); however, the level of optimal support has not been elucidated. We hypothesize that partial LVAD support in an ovine model of microinfarction-induced CHF significantly reduces left ventricular myocardial oxygen consumption (LVVO2). METHODS AND RESULTS(More)
BACKGROUND This study compared short-term and long-term outcomes in propensity score-matched patients with chronic kidney disease receiving bilateral internal thoracic artery (ITA) or single ITA grafting and assessed any benefit of bilateral ITA grafting for survival. METHODS Among 656 consecutive patients undergoing isolated coronary artery bypass(More)
OBJECTIVE The purpose of the present study was to investigate the association between preoperative C-reactive protein (CRP) and atrial fibrillation (AF) after isolated off-pump coronary bypass surgery. METHODS Of 683 consecutive patients undergoing isolated coronary bypass surgery by a single surgeon between January 2002 and March 2009, 552 were(More)
The effects of low-dose oral spironolactone (SPIRO) in a rat model of hypertensive heart failure (spontaneously hypertensive heart failure rat) were compared with its effects when combined with captopril (CAP). Twenty-six spontaneously rats with hypertensive heart failure were treated with either placebo (CON), SPIRO (20 mg/kg/d by mouth), CAP (100 mg/kg/d(More)
Giant coronary artery aneurysm is quite rare and the corresponding surgical strategy is difficult to standardize. We present the case of a patient with giant coronary aneurysm involving the left main coronary artery who underwent an aneurysmectomy and coronary artery reconstruction with direct suture of the coronary vessels. Because of compression of the(More)
