BACKGROUND: Erectile dysfunction (ED) and coronary artery disease (CAD) frequently coexist. ED may be present in the absence of cardiac symptoms 3-5 years before a coronary event. Exercise electrocardiography may identify flow-limiting CAD but cardiac computed tomography (CT) may identify early non-calcified plaque disease potentially vulnerable to rupture precipitating an ...

Maximal exercise capacity expressed as metabolic equivalents (METs) is rarely directly measured (measured METs; mMETs) but estimated from maximal workload (estimated METs; eMETs). We assessed the accuracy of predicting mMETs by eMETs in asymptomatic subjects. Thirty-four healthy volunteers without cardiovascular risk factors (controls) and 90 patients with at least one ...

Favorable effects of exercise training on cardiovascular prognosis have been reported repeatedly in patients with diabetes mellitus type 2 (DM2). However, little is known about the cardiovascular rehabilitation effects in diabetic patients with coronary artery disease (CAD). This study has evaluated the benefits of combined aerobic-resistance training in two groups ...

BACKGROUND: A positive noninvasive stress test result is often considered as a false-positive indicator of coronary artery disease (CAD) when coronary angiography reveals no hemodynamically significant CAD. METHODS: From January 2001 through December 2004, 5474 patients scheduled to undergo exercise electrocardiogram (ECG) [exercise ECG without imaging or exercise ECG with ...

An incremental response after brief exercise or high-rate stimulation on the repetitive nerve stimulation (RNS) test is a critical diagnostic criterion for Lambert-Eaton myasthenic syndrome (LEMS). This prospective study was performed to determine what duration of exercise shows the highest diagnostic sensitivity for LEMS. The compound muscle action potential amplitude ...

Physical and mental stressors result in increased inflammation markers in populations free of coronary artery disease (CAD). However, inflammatory responses to mental and exercise challenges have not been established in patients with CAD. This study investigated the responses of inflammatory markers, including C-reactive protein (CRP), interleukin-6 (IL-6), and soluble intercellular ...

BACKGROUND/PURPOSE: The diagnosis of coronary artery disease (CAD) in women presents a great challenge because of poor exercise capacity and inadequate heart rate response during stress test. The clinical significance of stress-related ST-segment/heart rate slope (ST/HR slope) value for evaluating CAD in women remains controversial. Therefore, we conducted the present ...

Recent studies showed that tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6), as well as high-sensitive C-reactive protein (hsCRP) levels are predictive factors of cardiovascular risk. However, the effect of cardiac rehabilitation (CR) intervention in coronary artery disease (CAD) patients on these factors is not known. The aim of this study ...

BACKGROUND: Fungemia has been historically considered to be a disease caused by a single Candida species; the detection of >1 species of yeast in circulating blood was distinctly uncommon using traditional microbiological procedures. We describe episodes of mixed fungemia (MF), detected between 1985 and 2006, in a large teaching hospital. ...

Acute physical exertion may trigger an acute coronary syndrome. Furthermore, acute physical exercise may influence hemostatic markers in healthy individuals. However, the effect of acute exercise on blood fibrinolysis and coagulation in patients with coronary artery disease (CAD) is still not well understood. Nineteen untrained patients with angiographically proven CAD ...

OBJECTIVE: Exercise electrocardiography is commonly available and a cost-effective test and therefore is widely used for the diagnosis of coronary artery disease. However, false positivity remains an important problem resulting in many unnecessary coronary angiographic examinations. In this study, we aimed to test the hypothesis that post-exercise B-type natriuretic peptides ...

The pathological processes underlying dementia are poorly understood and so are the markers which identify them. Carnosinase is a dipeptidase found almost exclusively in brain and serum. Carnosinase and its substrate carnosine have been linked to neuropathophysiological processes. Carnosinase activity was measured by a flourometric method in 37 patients attending ...

BACKGROUND: Peak exercise oxygen uptake (peakVO2) is a widely used prognosticator. Novel spirometric parameters, less affected by submaximal performance, such as the rate of increase of minute ventilation per unit decrease of carbon dioxide production (VE/VCO2 slope) and the oxygen uptake efficiency slope (OUES) have recently been introduced. AIM: To ...

The predictors for coronary artery disease (CAD) in patients with delayed systolic blood pressure (SBP) recovery after graded exercise are unclear. We studied 672 patients with preceding positive symptom-limited exercise treadmill testing (ETT) and underwent their first coronary angiography within 90 days to determine the high-risk profiles for angiographic CAD ...

One of the limitations of the current computer-aided detection (CAD) of polyps in CT colonography (CTC) is a relatively large number of false-positive (FP) detections. Rectal tubes (RTs) are one of the typical sources of FPs because a portion of a RT, especially a portion of a bulbous tip, often ...

BACKGROUND AND PURPOSE: The absence of xanthochromia in the cerebrospinal fluid (CSF) is often used to exclude subarachnoid hemorrhage (SAH). Authorities advocate spectrophotometry to measure xanthochromia, but most North American hospitals use visual inspection. We studied the diagnostic accuracy of spectrophotometry for SAH, and its potential impact on current practice. ...

Previous studies have demonstrated that in patients with coronary artery disease (CAD) upward deflection of the heart rate (HR) performance curve can be observed and that this upward deflection and the degree of the deflection are correlated with a diminished stress dependent left ventricular function. Magnesium supplementation improves endothelial function, ...
