Moyamoya disease is an occlusive intracranial arteriopathy owing to intimal hyperplasia with formation of abnormal cerebrovascular collateral networks; however, the etiology remains unclear. Although this disease is known to be associated with renovascular hypertension, it is extremely rare for it to be associated with stenoses of the coronary arteries. We herein described a case of a 56-year-o...

A 43-year-old man, with a past history of hypertension without regular medical control, presented to our hospital with intermittent chest tightness and shortness of breathing about one day. At emergent department, the blood pressure was 180/110 mmHg, and pulse rate was 78 beats per minute. Troponin I was 3.19 ng/ml. EKG showed V1-V4 ST elevation. Coronary angiography showed near total occlusion...

OBJECTIVE To compare cardiac troponin T release and lactate metabolism in coronary sinus and arterial blood during uncomplicated coronary grafting on the beating heart with conventional coronary grafting using cardiopulmonary bypass. DESIGN A prospective observational study with simultaneous sampling of coronary sinus and arterial blood: before and 1, 4, 10, and 20 minutes after reperfusion f...

Patients who underwent operations in which cardiopulmonary bypass was used had elevations of plasma fibrinopeptide A which did not return to normal during bypass despite conventional heparin anticoagulation, suggesting inadequate heparin dosage and continued thrombin activity during the operation. Patients who underwent aortocoronary artery grafting had high plasma thromboxane B2 levels and a r...

OBJECTIVE To investigate whether ischaemic preconditioning could reduce myocardial injury, as manifest by troponin T release, in patients undergoing elective coronary artery bypass surgery. DESIGN Randomised controlled trial. SETTING Cardiothoracic unit of a tertiary care centre. PATIENTS Patients with three vessel coronary artery disease and stable angina admitted for first time elective...

background  : on-pump coronary artery bypass graft (cabg) surgery impairs gas exchange in the early postoperative period. the main object on this study was evaluation of changes in arterial blood gas values in patients underwent on pump cabg surgery receiving different dose of intravenous nitroglycerin (ntg). methods : sixty-seven consecutive patients undergoing elective on-pump cabg randomly e...

abstract background and objectives: patients are oriented towards spirituality after coronary artery bypass grafting (cabg). the aim of this study was to explore the patients’ spiritual experiences after cabg. methods: this qualitative study was conducted using hermeneutic phenomenology. 11 participants (7 males and 4 females) were interviewed in tehran heart center hospital in 2013 using maxim...

background: redo coronary artery bypass grafting surgery (cabg) is associated with a higher risk of mortality than the first operation. however, the impact of percutaneous coronary intervention (pci) on the outcome in such patients is currently unclear. we evaluated the in-hospital and six-month clinical outcomes of post-cabg patients who underwent pci in our center. methods: between april 2008...

background : postoperative neurological injuries, including cognitive dysfunction, sleep disorder, delirium, and anxiety, are the important consequences of coronary artery bypass graft surgery (cabg). evidence has shown that postoperative sleep disturbance is partly due to disturbed melatonin secretion in the perioperative period. the aim of this study was to evaluate the effect of melatonin on...

at the final stages of a coronary artery bypass graft operation on a 64-year-old man, an experienced physician attempted to insert an intra-aortic balloon pump into the femoral artery via the seldinger technique. however, while the balloon pump was being passed over the guide wire, the latter was completely lost. the guide wire should be held at the tip at all times to prevent passage into the ...
