Objective: The aim of our study was to investigate the factors which cause prehospital and emergency department (ED) delays in acute stroke care. Subjects and Methods: We prospectively studied 229 acute stroke patients (median age: 71 ± 19 years, 90 female and 139 male) who presented to the ED of the Gulhane Military Teaching Hospital, Istanbul, Turkey. Prehospital delay was defined as time from symptom onset to arrival at the ED. Emergency delay was defined as time from initial examination in the ED to arrival at the Neurology Intensive Care Unit. Results: The median interval of prehospital and emergency delays were 92.66 and 53 min, respectively. The major cause of the prehospital delay was the time from symptom onset to first call for medical help (68.21 min, 73.93%, β coefficients: 0.99; p < 0.001), and the major cause of the ED delay was waiting for the neurological consultation (21.28 min, 39.6%), β coefficients: 0.03; p < 0.001). Conclusion: The results indicate that prehospital and ED delays are due to late decision to seek medical care and delayed neurological consultation. Hence, educational campaigns are needed to increase public awareness of stroke signs and the necessity of calling emergency services immediately when persons are suffering a possible stroke. Equally, ED physicians need to be trained in the recognition of symptoms and signs of acute stroke and the necessity for rapid neurological evaluation.

Left ventricular (LV) dilatation may be an early sign of cardiac decompensation progressing to LV dysfunction. Determinants of LV dilatation in young asymptomatic adults are unknown. Five hundred six asymptomatic subjects (mean age 32 +/- 3 years) enrolled in the Bogalusa Heart Study underwent echocardiographic examination. LV dilatation (LV end-diastolic diameter >5.5 cm) as measured by M-mode echocardiography was found in 31 subjects (6%). Subjects with LV dilatation had greater body mass indexes (32 +/- 9 vs 27 +/- 6 kg/m2, p <0.0001), systolic (119 +/- 15 vs 112 +/- 12 mm Hg, p = 0.007) and diastolic (79 +/- 12 vs 75 +/- 9 mm Hg, p = 0.04) blood pressures, and LV mass (230 +/- 50 vs 123 +/- 39 g, p <0.0001). Age, gender, race, and metabolic parameters (glucose, insulin, and lipoprotein levels) did not differ significantly between the subjects with and without LV dilatation. After correction for age, gender, and race differences, adulthood obesity (body mass index >30 kg/m2) was associated with a threefold odds ratio (2.9, 95% confidence interval 1.4 to 6.1), and hypertension (defined as per the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure) was also associated with a threefold odds ratio (3.0, 95% confidence interval 1.2 to 7.1) for an increased incidence of LV dilatation. There was an incremental increase in LV end-diastolic dimension depending on the presence of hypertension or obesity, and subjects with obesity and hypertension in adulthood had the greatest degree of LV end-diastolic dimensions. In multiple regression analyses, body mass index in childhood was the only significant predictor of LV dilatation in adulthood (odds ratio 1.47, 95% confidence interval 1.03 to 2.09). In conclusion, obesity beginning in childhood and obesity and hypertension in young adulthood are predictors of LV dilatation in an otherwise healthy young adult population.

Transthoracic echocardiography is a useful clinical tool for diagnosing noncompaction of both the right and left ventricular myocardium. The LVNC definition can also be utilized for RVNC, which this diagnosis has never been reported in a Turkish patient.

The objectives of this study are noninvasive assessment of endothelial dysfunction (ED) and diagnosing the possible early vascular development of atherosclerosis in psoriasis disease (PD). Twenty-eight PD patients (study group) without any obstructive vascular involvement were compared with 28 healthy controls (control group) in terms of ED utilizing endothelium-dependent dilation as well as endothelium-independent dilation, which was assessed by measuring changes in brachial artery diameter following sublingual glyceryl trinitrate (400 microg Nitrolingual spray). All patients underwent a complete transthoracic echocardiographic and tissue Doppler study. A standard form was utilized for the documentation of the presence or absence of the known risk factors for atherosclerotic vascular disease. Statistical analysis was performed by utilizing SPSS version 11. There was no difference between patients and controls in terms of echocardiographic and tissue Doppler parameters as well as baseline brachial artery diameters. Flow-mediated dilation showed 37% impairment in study group compared with control (p < 0.05). Endothelium-independent NTG dilatation did not differ in both groups. Noninvasive methods such as ultrasonography, saving time and cost-effective, can be utilized for following outpatient PD patients for the risk of ED, which may preclude to atherosclerosis.
