Retroperitoneal hemorrhage from iliac artery injury is a potentially serious complication of vascular interventional procedures leading to hemorrhagic shock and death if not diagnosed early and treated promptly. We report a 70-year-old male admitted to our facility with non-ST-elevation myocardial infarction, whose heart catheterization revealed left anterior descending artery (LAD) with 80% proximal, 95% mid and 100% distal disease. The left circumflex and right coronary arteries were 100% occluded proximally and received collaterals from the LAD...

Background: The aim of this study was to determine if breast arterial calcification (BAC) on mammography predicts myocardial ischemia (MI) on stress myocardial perfusion single-photon emission computed tomography (MPS). BAC is a type of medial artery calcification that can be seen incidentally on mammography, but the relationship between coronary artery calcification and MI on MPS is yet unknown. Methods: A total of 435 consecutive women underwent mammography and stress MPS within 1 year of each other...

The pathological technique is time consuming, costly, and patients are not preferred routinely. Histopathological findings have very low affectability and greater occurrence of β-errors, specifically in the diagnosis of cardiomyopathies. Angiography provides a two-dimensional view only. Vascular ultrasound elastography is a comparatively simple diagnostic method with a high resolution of images. The objective of this study was to compare the accuracy of ultrasound, followed by elastography with coronary angiography and endomyocardial biopsy, in the diagnosis of cardiovascular diseases in a Chinese population...

BACKGROUND: Exercise is a physiologic stress that helps the physicians to clarify the presence or absence of cardiovascular disease which may be obscure at rest. Although it is sensitive, its specificity is affected by several parameters, such as some metabolic conditions, some structural heart diseases, and some baseline electrocardiogram abnormalities. Currently, the relationship between coronary dominance and accuracy of EET is not examined. Therefore, this study was conducted to determine the potential impact of coronary dominance on the accuracy of EET...

OBJECTIVES: Although perioperative myocardial ischaemia (PMI) is a well-known complication following coronary artery bypass grafting (CABG), standard strategies for its diagnosis and treatment are so far not defined. In this study, we sought to evaluate the impact on survival of postoperative coronary angiogram for management of patients with PMI after CABG. METHODS: Overall, 4028 patients underwent isolated CABG in a single-centre institution between January 2006 and September 2013...

The decreased 123I-BMIPP uptake, while having normal perfusion, in the correspondent coronary artery territory is caused by a delayed metabolic recovery after the recovery of perfusion. This phenomenon termed ischemic memory can clearly differentiate vasospastic angina from other chest pain syndromes.

A 34-year-old woman presented to our service with chest pain, a troponin rise and dynamic ECG changes. Of note, she had complained of fatigue, feeling constitutionally unwell and a generalised rash in the days prior to her presentation. Her echocardiogram showed normal wall motion and preserved ejection fraction. Her eosinophil count, normal at presentation, rose to a peak of 12.21×10(5)/L. She was haemodynamically stable throughout with no evidence clinically of congestive cardiac failure. CT coronary angiogram showed no obstructive coronary artery disease...

The scanning-beam digital x-ray (SBDX) system is an inverse geometry x-ray fluoroscopy technology that performs real-time tomosynthesis at planes perpendicular to the source-detector axis. The live display is a composite image which portrays sharp features (e.g. coronary arteries) extracted from a 16 cm thick reconstruction volume. We present a method for automatically determining the position of the cardiac volume prior to acquisition of a coronary angiogram. In the algorithm, a single non-contrast frame is reconstructed over a 44 cm thickness using shift-and-add digital tomosynthesis...

Epicardial adipose tissue (EAT) is a particular form of visceral adipose tissue deposited around the heart and there is growing evidence about the physiological and metabolic importance of EAT, especially in the association of cardiovascular risk profiles and the pathogenesis of atherosclerotic coronary artery disease. This observational, cross sectional study was done to determine the relationship between echocardiographic epicardial adipose tissue (EAT) thickness and coronary artery disease (CAD). Total 123 patients with established or suspected coronary artery disease admitted for coronary angiogram in the department of Cardiology of Bangabandhu Sheikh Mujib Medical University (BSMMU) from November 2010 to the end of April 2011 were included in this study...

BACKGROUND: Anaphylaxis is an acute, potentially fatal medical emergency. Myocardial injury or infarction in the setting of an anaphylaxis can be due the anaphylaxis itself, when it is known as Kounis syndrome or it can also be due to the effect of epinephrine treatment. Epinephrine is considered as the cornerstone in management of anaphylaxis. Myocardial infarction secondary to therapeutic doses of adrenaline is a rare occurrence and only a few cases have been reported in literature...

A 45-year-old female was admitted for a transient anterior ST-segment elevation myocardial infarction (STEMI). Coronary angiogram showed a diffuse severe stenosis of the distal left anterior descending (LAD) coronary artery, which was managed medically. Three years later, a recurrent transient anterior STEMI led to a second coronary angiography showing a tubular stenosis of the mid-LAD with normal distal coronary bed. An optical coherence tomography (OCT) revealed a spontaneous coronary artery dissection (SCAD) with an extensive compressive mural hematoma without any intimal tear...

OBJECTIVE: Osteopontin is a component of atherosclerotic lesions, secreted by monocytes, macrophages and endothelial and vascular smooth muscle cells, which together are responsible for neointimal proliferation. We examined whether elevated plasma osteopontin concentration was associated with in-stent restenosis in patients with coronary artery disease. SUBJECTS AND METHODS: We enrolled 91 patients who underwent coronary artery stenting, and 60 control patients with normal findings on coronary angiography, between June 2012 and September 2013...

BACKGROUND: Women who have coronary artery disease (CAD) often present with atypical symptoms that may lead to misdiagnosis. We assessed strain, systolic strain rate and left ventricular dyssynchrony with 2- dimensional- speckle tracking echocardiography to evaluate its use as a non-invasive method for detecting CAD in women with normal ejection fraction compared with healthy women controls with a normal angiogram. METHODS: We included 35 women with CAD confirmed by coronary angiography and a positive exercise stress echocardiography and 35 women in a control group with a low pretest probability of CAD, normal angiogram and a normal stress echocardiography with normal EF...

Coronary artery disease (CAD) rates are higher in Asian-Indians than in Caucasians. CAD occurs at an earlier age in this group, with about a quarter of all myocardial infarctions occurring under the age of 40. Previous reports have suggested smaller coronary artery size in Asian-Indians as a major cause for increased CAD in this population. This study sought to evaluate the size of normal "atheroma-free" segments of the epicardial coronary arteries in Asian-Indians and Caucasians aged ≤40 years undergoing coronary artery intervention in other diseased segments...

INTRODUCTION: Endothelial dysfunction could contribute to the pathophysiology of angina pectoris (AP) in patients with normal coronary angiograms. Besides lipid-lowering effects, statins exert pleiotropic effects including improving endothelial function. MATERIAL AND METHODS: Our double-blind study included 58 patients with AP, noninvasively confirmed myocardial ischemia and a normal coronary angiogram. The effect of once-daily 20 mg atorvastatin (A) was compared with placebo (P) for 6 months...

BACKGROUND: Thrombocytosis and inflammation are vital elements in the pathogenesis of atherosclerosis. The platelet-to-lymphocyte ratio (PLR) is a novel biomarker that combines these parameters and has been shown to be associated with cardiovascular disease (CVD). This study aimed to determine whether PLR correlates with coronary artery disease (CAD) in high-risk patients, and if the relationship is affected by age. METHODS: Consecutive patients referred for coronary angiogram were evaluated (n=822)...

INTRODUCTION: Cerebrovascular accidents constitute the most common cause of disability all over the world. In India prevalence rate is 545 per 100000 and mortality rate is around 7.5 per thousand. Therefore the authors undertook a study on patients who underwent coronary artery bypass surgery (CABG). They were investigated for clinical and/or radiological evidence of cerebrovascular disease (CVD) with the aim to decide on early neurological intervention. PATIENTS AND METHODS: 210 patients who had undergone CABG were evaluated with neck vessel Doppler using high resolution duplex scanner system and computed tomography (CT) scan as well as MR angiogram (MRA) in addition to assessment of co morbid risk factors...
