BACKGROUND: Transient myocardial ischemia that is recorded on Holter monitoring after a myocardial infarction is known to be a risk factor of myocardial reinfarction or death. However, it is still uncertain whether transient myocardial ischemia is a cause of ventricular arrhythmias or is simply an indicator of severe coronary artery disease. Therefore, we have studied the relation of ventricular arrhythmias to transient myocardial ischemia detected on Holter monitoring after a myocardial infarction. METHOD: We studied 40 patients with acute myocardial infarction who were performed Holter monitoring, 7 to 14 days after an attack. On Holter monitoring, we analyzed the prevalence, characteristics of transient myocardial ischemia and its relation to ventricular arrhythmias. RESULTS: 1) Among 40 patients(32 men, 8 women, mean age 53+/-13), transient myocardial ischemia was recorded in 13 patients(33%). ST elevation was observed in 2 patients, and ST depression, in 11 patients. Total episodes of transient myocardial ischemia were 65, of which only one episode was accompanied by chest pain, and total daily episodes were 4.8+/-1.4. Total daily duration of transient myocardial ischemia was 61.4+/-15.5 minutes and the duration of each transient myocardial ischemia was 15.8+/-2.1 minutes. 2) There were no significant differences in frequencies of single ventricular premature beast, bigeminy, trigeminy, ventricular couplets, and ventricular tachycardias between two groups with and without transient myocardial ischemia. CONCLUSION: It is concluded that transient myocardial ischemia on Holter monitoring after myocardial infarction is not a cause of ventricular arrhythmias.

BACKGROUND AND OBJECTIVES: In radiofrequency surgery, energy is usually delivered to the submucosal tissue of the palate through a special probe in order to reduce the volume and rigidity (palatal channeling). However, the same probe can be used to make cuts in the free edge of the soft palate, as in laser-assisted uvulopalatoplasty [radiofrequency-assisted uvulopalatoplasty (RAUP)]. The objective of the current study was to evaluate the role of RAUP with tonsillectomy for the treatment of mild or moderate obstructive sleep apnea (OSA). MATERIALS AND METHODS: Eighty-two patients with mild to moderate obstructive sleep apnea (5< or =AHI<30, BMI<30) were included in this clinical trial. All patients received RAUP with tonsillectomy. Patients were followed for six months and were asked to respond to a questionnaire regarding standard visual analogue score pattern. Assessment was performed prior to the surgery and was repeated six month postoperatively. Visual analogue scores were measured for the parameters of pain, speech deficits, dysphagia and snoring (according to the partner). The Epworth sleepiness scale (ESS) was also utilized. Polysomnography was conducted preoperatively and was repeated six months postoperatively. RESULTS: There were significant differences in improvement of snoring, ESS and AHI before and after the procedure, and the success rate of the surgical treatment was 62%. Postoperative pain, speech disturbance, dysphagia were decreased two weeks after the operation. CONCLUSION: The results of the study suggest that RAUP with tonsillectomy is an effective treatment for patients with mild to moderate obstructive sleep apnea.
