Nocturnal angina: precipitating factors in patients with coronary artery disease and those with variant angina.
Factors precipitating nocturnal myocardial ischaemia were investigated in 10 patients with frequent daytime and nocturnal angina pectoris. Eight patients had fixed obstructive coronary artery disease or a low exercise threshold or both before the onset of ischaemia. Two patients had variant angina with normal coronary arteries and negative exercise tests. During sleep the electrocardiogram, ele...
متن کاملRisk factors among patients undergoing repeat aorta-coronary bypass procedures.
It is estimated that as many as 7% of patients who have an aorta-coronary bypass operation will require a second bypass procedure within 10 to 12 years. Using information from the Milwaukee Cardiovascular Data Registry, we matched 166 men who underwent two coronary bypass operations at least 6 months apart, between 1968 and 1981, with 428 patients who had a single procedure. Patients were match...
متن کاملSome reflections on the coronary bypass operation.
SUMMARY A promising new operation-coronary bypass-has been developed for the treatment of coronary heart disease. However, because of the nature of the underlying disease and the minute size of the vessels to be anastomosed, its long-range prospects are in doubt. At this point in time there is no evidence that the operation either prevents infarction or prolongs life, and great caution is urged...
متن کاملEffect of coronary artery bypass on QT dispersion
Introduction: QT dispersion (QT Max – QT min) reflects inhomogeneous ventricular depolarization that may provide a substrate for serious arrythmias and is associated with adverse clinical outcomes in patients with coronary artery disease. Some studies have shown reduction in QT dispersion after successful angioplasty due to coronary reperfusion, but effect of coronary artery bypass grafting o...
