Observation by an overnight sleep monitor and Holter recording were performed to study sleep-disordered breathing (oxyhemoglobin desaturations≥4% and apnea-hypopneas),heart rates, and ST-segment depressions (≥ 1mm, ≥1 min).Results Nocturnal ST-segment depressions occurred in 37 % of the patients. ST-segment depression within 2 min after an apnea-hypopnea or desaturation occurred in 17% of the patients. This temporal association was seen in 21% of the patients with nocturnal ST-segment depressions, more frequently in men (P<0.05) and more frequently in those with severe disordered breathing (P<0.05).Most of these ST-segment depressions were preceded by a series of breathing events: repeated apnea-hypopneas or desaturations or both in 73% of the patients. Conclusions Episodes of nocturnal myocardial ischemia are common in patients with angina pectoris. A temporal relationship between sleep-disordered breathing and myocardial ischemia was present in some of our patients, and occurs more frequently in men and in those with severely disordered breathing.

In case of low ischemic load, the treatment of stable refractory angina is aimed at symptom reduction. There are several new treatment methods targeting myocardial ischemia available, including coronary sinus flow reducer (CFR) implantation. Case Report: We report a case of a patient suffering from CCS class IV angina despite optimal medical therapy, with further revascualrization options exhausted, who was successfully treated with coronary sinus flow reducer (CFR). Besides technical skill to reach ostium of coronary sinus, the most important technical tip is precise positioning of the CFR. The reduction of angina symptoms started after epithelisation of CFR frame, usually 6 - 7 weeks after implantation. At 6-month follow-up, the patient reported a marked reduction of angina symptoms, with CCS grade improving by three classes (from IV to I). At 10-month follow-up, the sustainment of CCS grade I angina symptoms was reported by the patient. Conclusions: We conclude that CFR can be safely and successfully implanted in patients suffering from refractory angina. Considerable improvements in CCS grade may be experienced in certain cases.展开更多
