PURPOSE The purpose of this study was to identify predictors of contrast-induced acute kidney injury (CI-AKI) and the effect of CI-AKI on cardiovascular outcomes after hospital discharge in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). METHODS AND MATERIALS We(More)
We compared the effects of telmisartan and olmesartan in 20 patients with chronic heart failure and metabolic syndrome. The subjects underwent once-daily 40 mg telmisartan for at least 3 months before switching to once-daily 20 mg olmesartan for the next 3 months (post 1). They were then treated with 3 months of once-daily 40 mg telmisartan (post 2).(More)
Coronary artery fistulas, including coronary pulmonary fistulas, are usually discovered accidently among the adult population when undergoing invasive coronary angiographies. We report here a 58-year-old woman with dual fistulas originating from the left anterior descending coronary artery and right coronary sinus to the main pulmonary artery, demonstrating(More)
Tortuous coronary arteries frequently make percutaneous coronary intervention (PCI) difficult by causing less accessibility of guidewire toward the target lesion. After guidewire has been passed through the target lesion, it often assists a balloon catheter and stent system insertion along the stiff guidewire. However, artificial kinking and wrinkling might(More)
A 70-year-old woman was admitted to our hospital for a continuous heart murmur in the fourth intercostal space at the right sternal border. Routine echocardiography demonstrated aneurismal dilatation at the origin of right coronary artery. These findings suggested a coronary artery fistula, although its drainage site could not be identified. By shifting the(More)
BACKGROUND Interatrial septum pacing (IAS-P) decreases atrial conduction delay compared with right atrial appendage pacing (RAA-P). We evaluate the atrial contraction with strain rate of tissue Doppler imaging (TDI) during sinus activation or with IAS-P or RAA-P. METHODS Fifty-two patients with permanent pacemaker for sinus node disease were enrolled in(More)
