Delirium is reasonably prevalent in patients with acute MI. We propose that patients with the risk factors that have been delineated in this study should be evaluated carefully.

It is of clinical importance to determine creatinine clearance and adjust doses of prescribed drugs accordingly in patients with heart failure to prevent untoward effects. There is a scarcity of studies in the literature investigating this issue particularly in patients with heart failure, in whom many have impaired kidney function. The purpose of this study was to determine the degree of awareness of medication prescription as to creatinine clearance in patients hospitalized with heart failure. Patients hospitalized with a diagnosis of heart failure were retrospectively evaluated. Among screened charts, patients with left ventricular ejection fraction <40% and an estimated glomerular filtration rate (eGFR) of ≤50 mL/min were included in the analysis. The medications and respective doses prescribed at discharge were recorded. Medications requiring renal dose adjustment were determined and evaluated for appropriate dosing according to eGFR. A total of 388 patients with concomitant heart failure and renal dysfunction were included in the study. The total number of prescribed medications was 2808 and 48.3% (1357 medications) required renal dose adjustment. Of the 1357 medications, 12.6% (171 medications) were found to be inappropriately prescribed according to eGFR. The most common inappropriately prescribed medications were famotidine, metformin, perindopril, and ramipril. A significant portion of medications used in heart failure requires dose adjustment. Our results showed that in a typical cohort of patients with heart failure, many drugs are prescribed at inappropriately high doses according to creatinine clearance. Awareness should be increased among physicians caring for patients with heart failure to prevent adverse events related to medications.

We determined the role of anxiety level on radial artery spasm during transradial coronary angiography. Eighty-one patients who had an indication for coronary angiography were enrolled. Radial artery vasospasm was determined by addressing 5 signs: persistent forearm pain, pain response to catheter manipulation, pain response to sheath withdrawal, difficult catheter manipulation after being "trapped" by the radial artery, and considerable resistance on withdrawal of sheath. Radial spasm defined as at least 2 of the 5 signs. The Hamilton Anxiety scale questionnaire was used to determine the level of anxiety. Vasospasm was observed in 19.1% of the patients. Anxiety score was significantly higher in women (11.1 ± 7.2 vs 17.6 ± 7.3; P < .001). Vasospasm was significantly correlated with female sex (P < .001, r = .43) and anxiety score (P = .007, r = .29). Female sex was associated with higher anxiety scores (P < .001, r = .43). In conclusion, higher anxiety scores and female sex are important risk factors for radial artery vasospasm.

These results indicate that, whatever the mechanism is: 1) TCA is associated with female gender and short stature; 2) TCA is associated with subclinical atherosclerosis even in patients with entirely normal appearing coronary arteries on coronary angiography; 3) Retinal artery tortuosity is correlated with TCA and can be a surrogate for systemic arterial tortuosity.

Background:Acute pulmonary embolism (PE) is a life-threatening and a relatively common cardiovascular pathology. Although the pathogenesis of PE is well defined, there is no ideal diagnostic biochemical marker. Previous studies showed an increased ischemia modified albumin (IMA) levels in acute PE; however, the relationship between IMA and right ventricular (RV) dysfunction has not been examined. The aim of this study was to evaluate the diagnostic value of IMA and the relationship with RV dysfunction in acute PE.MATERIALS AND METHODS:A total of 145 patients (70 females) with suspected acute PE was enrolled to the study. Eighty-nine patients were diagnosed with acute PE via computed tomographic pulmonary angiography. Sixty-five patients with similar demographic and clinical characteristics were assigned to the control group. All patients were evaluated for RV dysfunction using transthoracic echocardiography.Results:Serum IMA levels were significantly increased in acute PE compared with control group (0.41 ± 0.06 vs. 0.34 ± 0.11, P = 0.001). There was no relationship between serum IMA levels and RV dysfunction. IMA levels were positively correlated with shock index and heart rate. Receiver operating curve analysis demonstrated that serum IMA levels higher than 0.4 put the diagnosis at sensitivity of 53.85% and at specificity of 85.96%.Conclusions:Although IMA levels are increased in patients with acute PE, it failed to predict RV dysfunction.
