Dual Energy Coronary Computed Tomography Angiography for Detection and Quantification of Atherosclerotic Burden : Diagnostic and Prognostic Significance
No full textPROGNOSTIC VALUE OF MULTIDETECTOR COMPUTED TOMOGRAPHY CORONARY ANGIOGRAPHY IN DIABETES: EXCELLENT LONG-TERM PROGNOSIS IN PATIENTS WITH NORMAL CORONARY ARTERIES
Full text linkObjective: To assess the prognostic role of multidetector computed tomography coronary angiography (MDCT-CA) in diabetics with suspected coronary artery disease (CAD). Use of MDCT-CA is increasing in patients with suspected CAD. However, data supporting its prognostic value in diabetics are limited.
Research Design and Methods: Between January 2006 and September 2007, 429 consecutive diabetic patients were prospectively studied with MDCT-CA for detecting presence and assessing extent of CAD (disease extension and coronary plaque scores). Patients were classified according to the presence of normal coronaries, non-obstructive (50%) coronary lesions. The composite rates of hard cardiac events (cardiac death, non-fatal myocardial infarction, unstable angina) and all cardiac events (including revascularization) were the end points of the study.
Results: Twenty-four patients were excluded because MDCT-CA data were uninterpretable. Of the remaining 405 patients, clinical follow-up (mean 62±9 months) was obtained in 390 (98%). By multivariate analysis, predictors of hard and all events were obstructive CAD, 3-vessel CAD and left main coronary artery (LMCA) disease. Cumulative event-free survival was 100% for hard and all events in patients with normal coronary arteries, 78% for hard events and 56% for all events in patients with non-obstructive CAD, and 60% for hard events and 16% for all events in patients with obstructive CAD. Three-vessel CAD and LMCA disease was associated with higher rate of hard cardiac events.
Conclusions: MDCT-CA provides long-term prognostic information in diabetics with suspected CAD, showing excellent prognosis when there is no evidence of atherosclerosis and allowing risk stratification when CAD is present

Cardiopulmonary exercise test evidence of isolated right coronary artery disease
No full textIsolated right coronary artery disease is usually difficult to diagnose because of frequent negativity of standard exercise stress test. We report a case of isolated coronary artery stenosis which was not detected by standard ECG stress testing. The cardiopulmonary exercise test showed a peculiar pattern: abrupt flattening in VO2/Work relationship, plateau in O2 pulse and 90 s afterwards a plateau in heart rate, probably related to vagal afferent stimulation by ischaemia of the postero-inferior wall of the left ventricle. Multidetector computed tomography of coronary vessels and coronary angiography confirmed isolated critical stenosis of middle right coronary artery. After revascularization by PTCA, normalization of cardiopulmonary exercise test was obtained
Exercise-induced changes in exhaled nitric oxide in heart failure
No full textIn heart failure abnormalities of pulmonary function are frequently observed as shown by hyperpnea, reduced lung compliance, reduced alveolar-capillary gas diffusion, positive methacholine challenge and, during exercise, early expiratory flow limitation. Nitric oxide (NO) might be related to all the above abnormalities
Unintentional embolization of a guide wire in the inferior vena cava during central venous catheter insertion successfully retrieved percutaneously nine months later
No full textCentral venous catheters are routinely positioned for hemodynamic monitoring and fluid administration in patients undergoing cardiac surgery, and many well-known complications associated with this manoeuver have been described. Metalic guide wire embolization is a rare complication potentially associated with nonmechanical and mechanical adverse events. The case we report is peculiar as an almost fully endothelialized guide wire was successfully retrieved 9 months after its unintentional embolization in the inferior vena cava. © 2013 Wiley Periodicals, Inc
