RESUMO

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.

RESUMO

Pharyngeal intubation is a challenging problem during transesophageal procedures. The rate of unsuccessful intubation varies from 1.5 to 1.9%. In this article, we described a novel technique, which we utilize in our hospital for the difficult intubations without any technical failure for the insertion of the transesophageal probe.

RESUMO

Hyperhomocysteinaemia is a well-known risk factor for cardiovascular disease and plays a role in atherothrombosis. Psoriasis is a common chronic and recurrent inflammatory skin disease associated with increased thrombosis. The aim of this study was to examine serum homocysteine levels and their relationships with inflammatory and atherothrombotic markers in psoriasis. Twenty patients with mild or moderate psoriasis and 20 age-matched healthy men were included in this study. Patients with acquired hyperhomocysteinaemia were excluded from both groups. The inflammation markers, mean platelet volume, C-reactive protein and ceruloplasmin levels, were significantly increased in the study group compared with the control group. In the study group there was decreased antithrombin III and total homocysteine levels, for haemostatic parameters. Folic acid levels, cardiovascular risk factors, endothelial inflammation markers and blood coagulation factors demonstrated significant correlations. Folic acid levels correlated inversely with homocysteine and positively with fibrinogen levels. In conclusion, increased homocysteine concentration and inflammation markers may play a role in the atherothrombotic state in psoriasis.

RESUMO

BACKGROUND: Long fasciotomy of the posterior aspect of the radial artery (RA) for the purpose of sympathectomy is one of the surgical techniques for the preparation of this graft. We compared the early results of this technique with those of the RA graft harvested as a pedicle in the conventional fashion. METHODS: The study patients have been selected from the patients who underwent coronary artery bypass grafting (CABG) using the RA graft harvested either with a long posterior fasciotomy (group 1) or as a whole with a pedicle in the classical manner (group 2). Only the patients with a flow study have been included. The flow index was described as the bleeding amount of the RA in a minute per body surface area (mL/m2 min). The flow index has been performed before and after fasciotomy in group 1, and after full skeletonization in group 2. The clinical and demographic parameters and flow indices were measured and compared between the groups, and in group 1, before and after fasciotomy. RESULTS: From 218 patients with CABG using the RA between January 1998 and August 2005, a total of 57 patients were recruited into the study. Group 1 consisted of 25 patients. Thirty-two patients constituted group 2. Subfascial dissection of the RA increased the blood flow index from 48 +/- 20 mL/m2 min to 51 +/- 19 mL/m2 min (p < 0.001). The comparison of the clinical, perioperative characteristics of the patients was not different between the groups. CONCLUSIONS: The necessity of total skeletonization of the RA should not be the only option when the aim is to reduce the spasm. While subfascial dissection (sympathectomy) of the pediculed RA alone provides a satisfactory increase in the blood flow index, it also reduces the manipulation time as well as the risk of injury to the graft.

RESUMO

Noninvasive assessment of endothelial dysfunction (ED) and diagnosing the early vascular development of atherosclerosis in active mucocutaneous Behçet's disease. Twenty-nine active BD patients (study group) without any obstructive vascular involvement were compared with twenty-nine healthy controls (control group) in terms of ED utilizing endothelium-dependent dilation as well as endothelium-independent dilation (FMD), which was assessed by measuring changes in brachial artery diameter following sublingual glyceril 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 38% impairment in study group compared with control (P<0.05). Endothelium-independent NTG dilatation did not differ in both groups. Ultrasonography is an easily applicable noninvasive method for following BD patients for the risk of ED, which may preclude to atherosclerosis, save time and cost-effective.

RESUMO

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.

RESUMO

BACKGROUND: Our aim was to investigate the effects of lipid-lowering treatment (LLT) on graft patency in coronary artery bypass grafting (CABG) patients. METHODS: A total of 209 CABG patients (95 men, 45%) with a total cholesterol level above 200 mg/dL and a low-density lipoprotein level above 100 mg/dL were included. Patients were divided into 2 groups on the basis of administration of LLT after CABG: group 1 received LLT after the operation (those patients undergoing operations after 1998, n = 102, 49% male) and group 2 did not receive LLT after the operation (those patients undergoing operations between 1992 and 1998, n = 107, 42% male). Median duration of follow-up was 5.2 years. Follow-up angiography could be obtained in 108 (52%) patients (56 in group 1, 52 in group 2). RESULTS: There was a 42% reduction in ischemic events and deaths in group 1, and 60% of these patients had a symptom-free or event-free period for 6 years. The 5-year graft patency for left internal mammary artery-to-left anterior descending artery grafts in group 1 was 95%, and the corresponding figure was 90% in group 2. Right coronary artery-to-saphenous vein graft patency was 66% for group 1 and 30% for group 2. Circumflex artery-to-saphenous vein patency rate was 59% for group 1 and 53% for group 2. A higher graft patency was found in group 1 as a whole. CONCLUSION: Results of this retrospective study support the fact that LLT provides a higher graft patency for CABG patients.

RESUMO

Our case is a 38-year-old man, admitted to Cardiology Department with shortness of breath. Echocardiography yields a hyperechogenic mass localized to papillary muscle with severe mitral regurgitation. Coronary angiography demonstrated radiopacity localized to the papillary muscle. The excision of the mass was consistent with elastic tumor, which was reported as papillary fibroelastoma attached to the papillary chordae of the mitral valve. A 29 no St-Jude bileaflet mechanical valve was implanted to mitral position. Papillary fibroelastoma (PF) can be found in young age and originate from the papillary muscle, which the radiopaque angiographic appearance of the mass supports the diagnosis.

RESUMO

OBJECTIVE: To report a case of comorbidity of constrictive pericarditis and hemophilia A. CLINICAL PRESENTATION AND INTERVENTION: A 21-year-old male with hemophilia A was referred to our clinic and was examined with the subsequent evaluation of shortness of breath, leg edema and ascites. Clinical and laboratory examinations were performed. The results were consistent with constrictive pericarditis (CP), and the symptoms were completely relieved following institution of medical therapy. CONCLUSION: Because hemophilia A and pericarditis may be coincidentally present clinical conditions, avoidance of surgical procedures in hemophilic patients is preferable unless the resolution of the symptoms of pericarditis cannot be effected by medical therapy.

RESUMO

This study aimed to investigate the aortic elastic properties of young pregnant women by comparing them with those of age-matched healthy females. The study group consisted of 21 pregnant women at a mean age of 26 +/- 1 years; 22 healthy women at a mean age of 25 +/- 1 years constituted the control group. Doppler-color echocardiographic variables and serum estradiol (E2) levels were measured from both groups. The blood samples were obtained from the control group in the first week after menstrual bleeding. Diastolic and systolic blood pressure (DBP and SBP, respectively) were measured with a sphygmomanometer. Systolic and diastolic aortic diameters (AOS and AOD, respectively) were measured 3 cm proximal to the aortic valves. Aortic elastic properties were assessed according to the following formulas: 1, Aortic strain = (AOS - AOD)/AOD; 2, Aortic distensibility = 2 x (AOS - AOD)/(PP x AOD); 3, Aortic diameter change = AOS - AOD; 4, Aortic stiffness index = ln(SBP/DBP)/(AOS - AOD)/AOD. The results were expressed as mean +/- standard deviation and compared by t-test between groups. P < 0.05 was considered as statistically significant. All women in the study group were in their first pregnancy and second trimester. The height and weight were 160 +/- 5 vs 164 +/- 6 cm and 60 +/- 9 vs 54 +/- 3 kg in the study vs control groups, respectively (P < 0.05). The AOD was 26 +/- 3 vs 26 +/- 4 mm and AOS 29 +/- 3 vs 28 +/- 4 mm. Pulse pressure was 43 +/- 3 vs 45 +/- 8 mmHg in the study vs control groups, respectively (P > 0.05). The serum E2 level was significantly higher in pregnant women (21 300 +/- 2 300 pg/ml). Derived aortic elastic properties in pregnant women were also increased significantly (P < 0.0005). The indexes of aortic elastic properties are altered and aortic stiffness is decreased among young pregnant women. This may be due to the adaptation mechanisms including high estradiol levels detected in pregnancy.

RESUMO

AIM: We aimed to present a case with ventricular myocardial noncompaction involving both ventricles. METHODS AND RESULTS: Noncompaction of ventricle is a rare and unclassified congenital cardiac malformation is due to an arrest in intrauterine endomyocardial morphogenesis. We presented a ventricular myocardial noncompaction case involving both left and right ventricles. The physical examination of this case is consistent with mitral regurgitation and the echocardiographic findings are consistent with noncompaction of ventricular myocardium involving both ventricles with left ventricular systolic failure. CONCLUSION: 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.

RESUMO

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%, beta 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%), beta 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.

RESUMO

Twelve-lead electrocardiograms revealed no atrial activity and a wide QRS escape rhythm at 38 beats/min in a 20-year-old man who presented with syncope. Doppler echocardiography documented the absence of A wave both in the tricuspid and mitral valve flow. The only mechanical activity was documented at the left atrial appendage. An electrophysiologic study demonstrated electrical inactivity in the right atrium and an atrial tachycardia in the left atrium. Atrial pacing with maximum output did not capture the atria. Our case represents an advanced stage of partial atrial standstill, with a mechanical and electrical atrial activity confined only to the left trial appendage. The patient remained asymptomatic after receiving a VVIR pacemaker and anticoagulation therapy.

RESUMO

OBJECTIVE: To determine the effects of nebivolol on diastolic functions of the left ventricle in the hypertensive patients in the early treatment period. METHODS: Twenty patients with mild to moderate hypertension taking daily 5 mg of nebivolol were assessed by using Doppler echocardiography before and after 6-week drug treatment period. The results were analyzed with Wilcoxon test and p<0.05 was accepted as statistically significant value. RESULTS: The arterial blood pressure and heart rate of the patients significantly decreased after 6 weeks of treatment. Statistically significant decrease was found in the peak of A wave velocity, isovolumetric relaxation time, E wave deceleration time and increase in E/A ratio with Doppler echocardiography after 6-week treatment period. No statistically significant difference was observed in the peak velocity of E wave after treatment period. CONCLUSION: We found that nebivolol improved left ventricular diastolic function in patients with hypertension in the early term.
