BACKGROUND The majority of women with angina-like chest pain have no obstructive coronary artery disease when evaluated with coronary angiography. Coronary microvascular dysfunction is a possible explanation and associated with a poor prognosis. This study evaluated the prevalence of coronary microvascular dysfunction and the association with symptoms,(More)
OBJECTIVES This study investigated whether digital reactive hyperemia index (RHI) measured by digital pulse amplitude tonometry is a sensitive indicator of coronary microvascular dysfunction (CMD). BACKGROUND CMD is an early marker of cardiovascular disease. However, CMD is a complex diagnosis and consists of multiple abnormalities of the coronary(More)
Colourectal cancer (CRC) is the fourth most common cause of death from cancer worldwide. While rates for CRC in adults age 50 and older have been declining, incidence rates in young adults, a population routinely not screened, has been increasing. We report a rare case of high-grade CRC in a previously healthy 27-year-old man, presented to us with symptoms(More)
BACKGROUND Cardiovascular disease has been the leading cause of death in both sexes in developed countries for decades. In general, men and women share the same cardiovascular risk factors. However, in recent trials including both men and women sexspecific analyses have raised awareness of sex differences in cardiovascular risk factors due to both(More)
BACKGROUND Coronary flow velocity reserve (CFVR) measured by transthoracic Doppler echocardiography is a noninvasive measure of microvascular function, but it has not achieved widespread use, mainly because of concerns of validity and feasibility. The aim of this study was to describe the feasibility and factors associated with the quality of CFVR obtained(More)
BACKGROUND The clinical presentation of ischemic heart disease in women differs from men, which could reflect sex-related differences of normal physiology. Cardiac CT angiography provides a noninvasive method to assess both regional and transmural myocardial perfusion in addition to coronary atherosclerosis. OBJECTIVE The aim of this study was to evaluate(More)
Congenital coronary artery fistula complicated with giant coronary artery aneurysm is a very rare condition. In this case report, we present a 65-year-old woman, referred to us with a continuous heart murmur, occasional atypical chest pain and few episodes of fainting. A giant aneurysm and a coronary-pulmonary fistula were diagnosed using multiple(More)
OBJECTIVE The construct of vital exhaustion has been identified as a potential independent psychological risk factor for incident and recurrent coronary heart disease (CHD). Despite several decades of research, no systematic review or meta-analysis has previously attempted to collate the empirical evidence in this field. The purpose of this study was to(More)
Trained breath-hold divers hyperinflate their lungs by glossopharyngeal insufflation (GPI) to prolong submersion time and withstand lung collapse at depths. Pulmonary hyperinflation leads to profound hemodynamic changes. Thirteen divers performed preparatory breath-holds followed by apnea with GPI. Filling of extrathoracic veins was determined by ultrasound(More)
