OBJECTIVES The purpose of this study was to determine whether a diminished cardiac pain threshold contributes to chest pain in patients with syndrome X. BACKGROUND There have been some reports of an altered pain perception in syndrome X. METHODS Intracardiac catheter manipulation was performed in four groups of patients (syndrome X [group 1, 36 patients]; mitral valve disease and normal cor...

INTRODUCTION EKG remains a highly valuable tool for heart disease management. Corrected QT interval dispersion is a useful EKG parameter to assess prognosis in ischemic heart disease and specifically acute coronary syndrome. Understanding QT interval physiopathology helps assess importance of QT measurement in this context. Although increased QT dispersion is an ominous prognostic marker, its u...

INTRODUCTION AND OBJECTIVES The role of high-density lipoproteins in the context of acute chest pain has not been well characterized. The objective of this study was to determine the relative contribution of lipid profile to the risk of acute coronary syndrome in patients admitted to a cardiology ward for chest pain. METHODS We included all consecutive admissions in a single cardiology depart...

The prevalence of microvascular angina is estimated to be up to 30% of stable angina patients with nonobstructive coronary arteries. 19% of women presenting with acute coronary syndrome, 30% of women presenting with unstable angina, 9.1% of women with non-ST-elevation myocardial infarction and 10% of women with ST-elevation myocardial infarction were determined to have normal or non-obstructive...

Subclavian steal syndrome is known as reverse flow from vertebral artery to subclavian artery due to occlusion of proximal subclavian artery. Occlusive process leading to syndrome is common in left subclavian artery. Coronary-subclavian steal syndrome may happen by reverse flow in left internal thoracic artery with occlusion in subclavian artery of patients who were performed coronary artery by...

Introduction: Cardiovascular disease (CVD) is a group of diseases that include both the heart and blood vessels, thereby including coronary (CHD) artery (CAD), acute syndrome (ACS) among several other conditions.

A rare clinical variant of angina manifestation as part the coronary steal syndrome in a patient with prior bilateral artery bypass grafting and subtotal brachiocephalic trunk stenosis is considered.

The prevalence of microvascular angina is estimated to be up to 30% of stable angina patients with non-obstructive coronary arteries. 19% of women presenting with acute coronary syndrome, 30% of women presenting with unstable angina, 9.1% of women with non-STelevation myocardial infarction and 10% of women with ST-elevation myocardial infarction were determined to have normal or nonobstructive ...

Adipose tissue-derived serine protease inhibitor (vaspin), which has endocrine and local roles in atherosclerosis growth, is also synthesized by adipose tissue; it was found that vaspin was negatively correlated with blood pressure in obese patients, while vaspin levels were decreased in endothelial dysfunction. The aim of the present study was to determine rosuvastatin modulation effects on se...

INTRODUCTION Although several etiopathogenetic mechanisms have been proposed, the causes of left ventricular apical ballooning syndrome are still controversial. CASE PRESENTATION A 51-year-old Japanese woman consulted the emergency room complaining of the sudden onset of anterior chest pain while shopping. We initially suspected her disease as left ventricular apical ballooning syndrome based...
