PURPOSE Endoplasmic reticulum (ER) stress has recently been observed to activate NF-kappaB and induce inflammatory responses such as asthma. Activating transcription factor 6β (ATF6B) is known to regulate ATFα-mediated ER stress response. The aim of this study is to investigate the associations of ATF6B genetic variants with aspirin-exacerbated respiratory disease (AERD) and its major phenotype...
BACKGROUND The autonomic nervous system is reported to be involved in the pathogenesis of vasospastic angina (VSA). Studies based on heart rate variability analysis have shown conflicting results with both a reduction and an enhancement of sympathetic nervous system (SNS) activity in patients with Prinzmetal's variant angina, but direct assessment has never been performed. The aim of our study ...
Objective Sarcomeric gene mutation carriers without overt left ventricular hypertrophy (G+/LVH-) can harbour subclinical changes in cardiovascular structure and function that precede the development of hypertrophic cardiomyopathy (HCM). We sought to investigate if circulating biomarkers of cardiovascular stress and collagen metabolism among G+/LVH- individuals, measured at rest and following ex...
This study addresses the intended escalatory tendency in eight hypothetical situations in which the provocator's identity (partner or stranger, male or female) and the provocation form (verbal or physical aggression) were manipulated. The research question is "how does the identity of the provocator and the form of his or her provocation affect the participant's intended escalation level, and d...
OBJECTIVES In patients with chest pain suggestive of variant angina, we performed this prospective study to test the specificity and diagnostic validity of ergonovine echocardiography (detection of regional wall motion abnormality during bedside ergonovine challenge) as a screening procedure before coronary angiography. BACKGROUND Spasm provocation test outside the catheterization room has ge...
As pharmacological spasm provocation tests, acetylcholine (ACh) [1-3] and ergonovine (ER) [4,5] are employed in the cardiac catheterization laboratory. However, we often encounter the major and minor complications during performing these procedures. As a diagnostic tool, we should perform spasm provocation tests more safely without major complications. Multiple and proximal spasm documented by ...
