Background: Pulse pressure has recently been considered as a predictor of coronary heart disease. The difference between systolic and diastolic blood pressure is called pulse pressure. Various factors including increased age, vascular stiffness, stenosis, and hypertension are associated with pulse pressure. The present study, therefore, aimed to investigate the relationship between some cardiov...

The effects of experimentally induced, severe coronary artery stenosis on regional changes in myocardial blood supply, cardiac function, and metabolism were studied in 14 dogs. The anterior interventricular branch of the left coronary artery (LAD) was constricted such that arterial inflow was reduced by 80%. Nine dogs were given enflurane in a concentration of 2.2 vol.% (1 MAC) in air, and five...

background: the incidence of stroke is 2.1-5.2% in bypass surgery patients with a mortality of 0-38%. this study was designed to evaluate the incidence of significant carotid artery stenosis and its related risk factors in candidates for coronary artery bypass graft (cabg) surgery. methods: 1045 consecutive candidates for cabg underwent carotid artery doppler examination in a prospective study....

A 69-yrs-old woman with anomalous origin of the right coronary artery from the opposite sinus of Valsalva (ACAOS) was diagnosed as having infective endocarditis affecting the aortic valve. Transthoracic echocardiography showed severe aortic stenosis and vegetations on the cusp of the aortic valve, which necessitated aortic valve replacement. Before the operation, computed tomography showed a ri...

impaired fasting glucose identifies individuals at high risk of progression to diabetes but the role of ifg as a coronary artery disease risk factor, independent of its progression to diabetes and its association with other coronary artery disease risk factors ,is unclear. a cross-sectional study was conducted to evaluate the hypothesis that impaired fasting glucose increased the likelihood of ...

 Introduction: Prevalence of stroke following coronary artery bypass graft surgery (CABG) is % 2.1-5.2 and associated with high mortality. The purpose of this study was to investigate the prevalence of carotid artery disease in patients undergoing CABG surgery.  Methods: This cross-sectional study was performed in the years 2010-2011 on 192 patients who underwent open heart surgery (CABG) in...

Background—Percutaneous coronary interventions (PCIs) in saphenous vein grafts (SVGs) with thrombus have a high frequency of distal embolization. Acolysis (therapeutic ultrasound) can break up thrombus in vitro in animal models and humans. Whether this is beneficial during percutaneous SVG interventions is unknown. Methods and Results—We performed a trial of coronary ultrasound thrombolysis in ...

Background: The use of Y-shaped aorto-coronary saphenous vein grafts is most commonly driven by efforts to replace the poor quality (length) of the vein grafts or to minimise manipulation of the atheromatous ascending aorta (Jarvis [1]). We found only a few case reports describing PCI of bifurcation lesions in vein grafts in the available scientific literature (Karalis [2], Prosser and Bailey [...

BACKGROUND Central vein stenosis or occlusion is a common complication that can lead to significant morbidity and dysfunction of access in the hemodialysis patient. More lesions can develop over time, and preserving access becomes a challenge as life expectancy of the hemodialysis patient increases. OBJECTIVES The goal was to compare long-term results and determine the outcomes of open-cell s...
