Two patients with angina pectoris and postmyocardial infarction angina due to coronary vasospasm at the site of myocardial bridge are described. Intracoronary injection of isosorbide dinitrate led to resolution of coronary vasospasm on acetylcholine provocation test, and vasospastic angina pectoris has been well controlled after treatment with calcium(More)
Myocyte loss and replacement fibrosis have been observed in patients with hypertrophic cardiomyopathy (HC) with heart failure. This study was designed to elucidate whether heart-type fatty acid-binding protein (H-FABP), a sensitive biochemical marker for myocardial damage, indicates ongoing myocardial damage in patients with HC. We studied 48 patients with(More)
The patient was a 37-year-old female who had undergone a repair for tetralogy of Fallot (TOF) at the age of 4 years. Postoperative pulmonary stenosis remained, but she continued to be managed medically. Approximately 3 years ago, at the age of 34, she exhibited a worsening of fatigue and dyspnea during exertion (New York Heart Association III), and was(More)
A 67-year-old woman with hypertrophic obstructive cardiomyopathy that was refractory to medical treatment underwent percutaneous transluminal septal myocardial ablation (PTSMA). The septal branch supplying the myocardium involved in the left ventricular outflow tract (LVOT) obstruction was identified by selective myocardial contrast echocardiography (MCE).(More)
BACKGROUND AND AIMS It has been proven that a disturbance in angiogenesis contributes to the progression of myocardial interstitial fibrosis in idiopathic dilated cardiomyopathy (DCM). This study was designed to evaluate the relationship between serum activity of angiogenic factors and myocardial ultrasonic tissue characterization in patients with DCM. (More)
BACKGROUND Visual or quantitative assessment of coronary angiography may not exactly predict the physiological significance of intermediate (40-70%) coronary stenosis. Coronary flow reserve is a well-established marker of the functional significance of coronary stenosis. OBJECTIVES The aim of this study was to compare the coronary flow velocity reserve(More)
BACKGROUND This study assessed the feasibility of transthoracic Doppler scan echocardiography (TTDE) combined with echo-contrast agent in measuring coronary flow velocity (CFV) and coronary flow velocity reserve (CFVR) in the left anterior descending artery. METHODS In 68 consecutive patients who underwent cardiac angiography, TTDE was recorded before and(More)
We have evaluated cefixime (CFIX) fine granules for pharmacokinetics and therapeutic effectiveness in children with infections. The results were summarized as follows. Pharmacokinetic parameters after the oral administration of single doses of 1.5 mg and 6.0 mg per kg body weight in a cross-over design in 1 child were as follows: The peak serum CFIX(More)
An 81-year-old man with effort angina pectoris underwent coronary artery bypass grafting operation using the bilateral internal thoracic arteries and the right gastroepiploic artery (GEA). Angiography after operation showed that the bilateral internal thoracic arteries were patent. Abdominal angiography showed severe ostial stenosis in the celiac trunk. The(More)
