BACKGROUND Calcium antagonists (Ca) have been effective in reducing angina attacks in patients with variant angina. However, there are no reports regarding the effectiveness of Ca on myocardial fatty acid metabolic images in patients with pure coronary spastic angina (CSA). OBJECTIVES This study sought to examine the correlation between myocardial fatty acid metabolic images and the medical t...

Myocardial ischemia (MI) resulting in infarction is an important cause of mortality and morbidity worldwide. Acute ischaemia rapidly impairs myocardial contractile function. Myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. Hibernation is now thought to be the consequence o...

The effects of exercise training on metabolic and functional recovery after myocardial transient ischemia were investigated in a rat model. Male Wistar Kyoto rats were subjected either to a 30-min left coronary artery occlusion followed by reperfusion or to a sham operation. At 4 weeks after operation, the rats were randomly assigned either to sedentary conditions or to exercise training for 6 ...

BACKGROUND It remains unclear whether spontaneous anterograde flow preserves myocardial fatty acid metabolism in patients with acute myocardial infarction (AMI). METHODS AND RESULTS The present study comprised 129 patients with a first anterior AMI in whom Thrombolysis in Myocardial Infarction (TIMI) 3 flow was obtained on the final angiogram: 28 patients with spontaneous anterograde flow and...

A 74-year-old Japanese male was referred to our hospital because of an abnormal electrocardiogram. The electrocardiogram revealed tall P waves in leads II, III, and aV(F). Echocardiography disclosed hypokinesis extending from the anteroseptal region to the apex. Iodine-123 15-(p-iodophenyl)-3-(R,S)-methylpentadecanoic acid (123-BMIPP) scintigraphy revealed reduced uptake from the anteroseptal r...

Objective—To determine the clinical and prognostic value of identifying metabolic abnormalities of myocardial fatty acid metabolism in idiopathic dilated cardiomyopathy using iodine-123 â-methyliodophenyl pentadecanoic acid (I BMIPP). Setting—Cardiac care division in national hospital. Patients—32 consecutive patients with idiopathic dilated cardiomyopathy in whom both I BMIPP and thallium-201 ...

INTRODUCTION The study was designed to clarify the role of (123)I-β-methyl-iodophenylpentadecanoic acid ((123)I-BMIPP) in the evaluation of myocardial fatty acid metabolism in patients with stable angina pectoris (AP) before and after percutaneous coronary intervention (PCI). MATERIAL AND METHODS TEN CONTROLS (MEAN AGE: 70.4 ±10.5 years) and 12 patients with AP (mean age: 67.4 ±11.6 years) an...

OBJECTIVES The aim of this study was to assess the prognostic value of the amount of perfusion-metabolic mismatch in revascularized patients with left ventricular (LV) dysfunction by means of Thallium (Tl)-201 and BMIPP imaging. METHODS Seventy-six patients with LV dysfunction and coronary artery disease underwent Tl-201 and BMIPP imaging. They were revascularized with either coronary artery ...

BACKGROUND Nicorandil (NCR) has been reported to have cardioprotective effects in patients with AMI. And collateral flow and TIMI flow are also important determinants of final salvaged myocardium in patients with AMI. There is no evidence as to whether TIMI or collateral flow modifies the cardioprotective effects of NCR in patients with AMI. METHODS AND RESULTS We studied 68 initial AMI patie...

Churg-Strauss syndrome is characterized by asthma, eosinophilia and systemic necrotizing vasculitis; cardiac involvement (ie, eosinophilic heart disease) is the major cause of morbidity and mortality, although there are no reports of an association between left ventricular dysfunction because of eosinophilic heart disease and myocardial blood flow or myocardial fatty acid metabolism. A patient ...
