RESUMEN
BACKGROUND: To our knowledge, the early effect of the fear caused by terrorism on human health, especially its effect on the number of visits to medical emergency departments (EDs), has not yet been studied. OBJECTIVES: To observe the effect of fear from terrorist alerts on the use of EDs and on the rate of cardiovascular (CV) and/or cerebrovascular events. SETTING: In Istanbul, Turkey, there was a terror alert on the weekend of 19 and 20 March 2016. In this multicenter retrospective study, we compared the data of patients from that weekend with those from the preceding and following weekends. PATIENTS: A total of 12 324 adult patients' records were included in this study: 4562 patients in the first weekend, 3627 patients in the second, terror alert weekend, and 4135 patients in the third weekend. MEASUREMENTS: The ED, CV, and cerebrovascular incidence rates of the above three groups were compared. RESULTS: The rate of ED use was the least in the weekend of the terror alert; the highest rate occurred during the weekend prior to it (female applications decreased more [P = 0.03]). The medical center that was the farthest from the crowded central places of the city and from the place where suicide bombing occurred was less affected by the decrease in use. CONCLUSIONS: Fear associated with terrorism may affect human health indirectly by preventing patients from reaching the necessary emergency healthcare facilities. This finding may be a pathfinder to decision-makers in such extraordinary emergency conditions. Further studies are needed in this field.

BACKGROUND: Although several clinical trials have compared surgical outcomes between off-pump and on-pump coronary artery bypass grafting (CABG), whether there is a difference in the early- and medium-term postoperative coronary microvascular functions is not fully understood. We compared short- and medium-term coronary microvascular function after off-pump and on-pump CABG. METHODS: A prospective study of patients undergoing off-pump and on-pump CABG. Eighty-two patients scheduled for CABG were recruited: 38 underwent off-pump surgery and 44 on-pump surgery. Each participant's coronary flow reserve (CFR) and diastolic function were measured with transthoracic Doppler echocardiography six and 12 months after surgery. RESULTS: Baseline and hyperaemic diastolic peak flow velocity in the left anterior descending artery were similar in both groups, as was CFR (2.22±0.66) in the off-pump group compared with (2.13±0.61) in the on-pump group, (P=0.54). Coronary flow reserve was significantly and inversely correlated with high sensitivity C-reactive protein concentration (r=-0.416; P<0.001) and positively correlated with mitral E/A-wave velocity ratio (r=0.247; P=0.02). Stepwise linear regression analysis revealed that only high sensitivity C-reactive protein concentration was independently correlated with CFR (ß=-0.272, P=0.02). CONCLUSIONS: Heart-lung bypass technique had no medium-term influence on the coronary microcirculation, despite a possible initial unfavourable effect. Serum hs-CRP concentration was an independent predictor of medium-term coronary microvascular dysfunction.

BACKGROUND AND AIM: Increased incidence of coronary vascular events in patients with inflammatory bowel disease (IBD) is known. However, the association between coronary microvascular function and IBD has not been fully defined. We aimed to investigate whether coronary flow reserve (CFR) and left ventricular diastolic function were impaired in IBD patients. METHODS: Seventy-two patients with IBD (36 patients with ulcerative colitis [UC] and 36 Crohn's disease [CD]) were registered. Each subject was evaluated after a minimum 15-day attack-free period. For the control group, 36 age- and sex-matched healthy volunteers were included into the study. IBD clinical disease activity in UC was assessed by the Truelove-Witts Index (TWAS) and in CD by the Crohn's Disease Activity Index (CDAI). In each subject, CFR was measured through transthoracic Doppler echocardiography. RESULTS: Compared to the controls, the CD group and UC group had significantly higher high-sensitivity C-reactive protein (hs-CRP) and erythrocyte sedimentation rate. Baseline diastolic peak flow velocity (DPFV) of the left anterior descending artery (LAD) was significantly higher in the IBD group (24.1±3.9 vs. 22. 4±2.9, p<0.05), and hyperemic DPFV (56.1±12.5 vs. 70.6±15.3, p<0.05) and CFR (2.34±0.44 vs. 3.14±0.54, p<0.05) were significantly lower in the IBD group than in the control group. In stepwise linear regression analysis, hs-CRP and lateral Em/Am ratio were independently correlated with CFR. CONCLUSION: CFR, reflecting coronary microvascular function, is impaired in patients with IBD. CFR and left ventricular diastolic function parameters are well correlated with hs-CRP.

BACKGROUND: Serum uric acid is related to hypertension and cardiovascular diseases. Masked hypertension is associated with an increase in cardiovascular risk. The aim of our study was to evaluate the serum uric acid level and its relationship with carotid intima-media thickness (IMT) in patients with masked hypertension. SUBJECTS AND METHODS: A total of 114 untreated masked hypertension patients (62 men, 52 women; mean age 44.6 +/- 7.9 years) and 38 controls (20 men, 18 women; mean age 44.8 +/- 7 years) were included in the study. All patients underwent 24-hour ambulatory blood pressure. Serum uric acid and carotid IMT were measured. RESULTS: Serum uric acid was significantly higher in masked hypertension patients when compared to the control group (5.14 +/- 1.42 mg/dl, 4.84 +/- 1.45 mg/ dl, P = 0.01). Masked hypertension patients had significantly higher carotid IMT than control subjects (0.58 +/- 0.09, 0.52 +/- 0.09, P < 0.001). The masked hypertension group was also divided into two groups according to the median value of the serum uric acid levels (median value: 5 mg/dl). Carotid IMT was significantly higher in patients with a higher uric acid when compared to those with a lower uric acid (P < 0.001). We also found that the serum uric acid level was a good predictor of increased carotid IMT at the receiver-operating characteristic curve.The area under the curve was 66% (95% confidence interval, 0.56-0.77), and the serum uric acid level was significantly predictive of a high carotid IMT (P = 0.001). CONCLUSIONS: Our data suggest that the uric acid levels were significantly higher in the masked hypertension group and elevated uric acid levels were associated with increased carotid IMT, indicating that elevated serum uric acid levels might contribute to the increase in cardiovascular risk in masked hypertension.

SUBJECTS: Thirty-six patients with psoriasis and 56 healthy volunteers were included in this study. METHODS: Echocardiographic examination included transmitral peak flow velocities of the early phase (E) and late phase (A) of the mitral inflow, left ventricular myocardial velocity measurements, and coronary flow reserve (CFR) measurement. RESULTS: Baseline coronary diastolic peak flow velocity (DPFV) of left anterior descending artery (LAD) was significantly higher in the psoriasis group. However, hyperemic DPFV was slightly lower and CFR (2.19 ± 0.39 vs. 2.60 ± 0.31, P < 0.0001) was significantly lower in the psoriasis group than in the control group. CFR was significantly and inversely correlated with disease duration, Psoriasis Area and Severity Index (PASI) score, and hsCRP. CONCLUSION: CFR is decreased in patients with psoriasis, and it correlates to disease duration, PASI score, and inflammation.

In this study, we have measured coronary flow reserve (CFR) using transthoracic echocardiography and brachial artery flow-mediated dilatation using vascular ultrasound in 36 subjects with masked hypertension (MH), 62 patients with sustained hypertension (SH), 40 patients with white-coat hypertension (WCH), and 39 healthy volunteers. CFR was significantly lower in the MH and SH groups (2.30 ± 0.39 and 2.28 ± 0.52, respectively) than in the control and WCH groups (2.85 ± 0.39 and 2.77 ± 0.41, respectively; P < .05). CFR was significantly impaired in patients with MH and SH compared with WCH and normotensive subjects. MH and SH groups are comparable with regard to cardiovascular risks and target organ damage.

Subclavian venous obstruction is a disorder that arises more frequently today, due to the increased frequency of vascular interventions. It may affect one or both of the subclavian veins. When bilateral, it complicates the implantation of several devices that are preferably installed via the upper-extremity veins. Among these are pacemakers, cardiac defibrillators, catheters for haemodialysis, and even port catheters. In this study, we present a patient with symptomatic Mobitz type II AV block, who was planned to undergo a pacemaker implantation. Previously the patient had undergone two coronary bypass operations. Probably due to the interventions made at that time, he was now diagnosed with bilateral subclavian vein obstruction. Following the diagnosis, the obstruction in the right subclavian vein was successfully relieved through balloon angioplasty, after which a permanent atrioventricular pacemaker was installed.

OBJECTIVE: The present study was undertaken to test the hypothesis that smoking induces peripheral endothelial dysfunction and altered function in central conduit arteries. METHODS: A total of 22 healthy volunteers (10 women and 12 men; mean age 25.3 +/- 5.8 years) were included. At baseline, brachial artery flowmediated dilatation (FMD), aortic stiffness index (ASI), aortic distensibility (AoD), and aortic elastic modulus (AoEM) of all subjects were measured. On the 2nd day, the subjects were assigned to smoke either 1 light (0.6 mg of nicotine, 8 mg of tar, and 9 mg of carbon monoxide) or 1 regular cigarette (0.9 mg of nicotine, 12 mg of tar, and 12 mg of carbon monoxide) and the measurements were repeated for all subjects 20 minutes following smoking. After 15 days, the subjects were assigned to smoke 1 cigarette of the type that was not smoked on the 2nd day, and the same measurements were performed 20 minutes after smoking. RESULTS: In response to smoking 1 light cigarette, FMD values declined from 15.0 +/- 6.8% to 9.1 +/- 2.9% (P = 0.002). After smoking 1 regular cigarette, FMD values declined from 15.0 +/- 6.8% to 9.4 +/- 4.8% (P= 0.002). Aortic elasticity and left ventricular diastolic functions (LVDF) were significantly impaired by both types of cigarettes. CONCLUSION: Smoking light cigarettes has similar acute detrimental effects on FMD, LVDF, ASI, AoD, and AoEM as regular cigarettes.

RATIONALE: Carbon monoxide (CO) poisoning is associated with direct cardiovascular toxicity. In mild CO poisoning in which cardiovascular life support is not required, the effects of CO on left and right ventricular functions are unknown in patients without cardiac failure. OBJECTIVES: Echocardiography was used to determine whether or not mild CO poisoning impairs ventricular function. Twenty otherwise healthy patients with CO poisoning and 20 age- and gender-matched controls were studied. Echocardiographic examinations were performed at the time of admission and 1 week after poisoning. RESULTS: The impairment observed in the left and right ventricular diastolic function at the time of admission was greater than the impairment 1 week after poisoning. Mild CO poisoning did not have a significant effect on systolic function. Carboxyhemoglobin levels were positively correlated with left ventricular diastolic dysfunction, whereas the levels were not correlated with right ventricular diastolic function. CONCLUSIONS: In CO intoxication, the development of left and right ventricular diastolic dysfunction precedes systolic abnormality. Patients with mild CO poisoning do not manifest cardiovascular symptoms; however, it should be borne in mind that most of these patients have myocardial involvement.
RESUMEN
BACKGROUND: Smokeless tobacco use is common in various parts of the world. In Turkey a type of smokeless tobacco called "Maras powder" is widely used in southeastern region. Smoking is known to have an adverse effect on nitric oxide and cardiovascular risk factors. The aim of this study was to evaluate whether there is difference between the effects of Maras powder and cigarette smoking on the cardiovascular risk factors and nitric oxide levels. METHODS: In the study, participants were 48 Maras powder users, 50 cigarette smokers and 45 nontobacco user subjects. Blood samples were collected and hematological parameters and lipid parameters were measured. Plasma Nitric oxide level was also detected by using the Griess method. RESULTS: Plasma total cholesterol, LDL-cholesterol, triglyceride levels were significantly higher in Maras powder and cigarette smokers group than in the nontobacco user group (p<0.001). Plasma HDL-cholesterol levels were significantly lower in Maras powder and cigarette smokers group than in the nontobacco user group (p<0.001). Plasma Nitric oxide levels were found significantly lower in Maras powder and cigarette smokers group compared to the nontobacco user group (4.9±0.9 µmol/l, 4.8±1 µmol/l, 9.4±3.4 µmol/l, respectively, p<0.001) whereas there was no significant difference between the Maras powder and cigarette smokers group. In multivariate logistic regression model, cigarette smoking (Odds ratio=17.832, p<0.001), Maras powder usage (Odds ratio=12.311, p=0.002) and mean platelet volume (Odds ratio=1.425, p=0.030) remained independently associated with lower Nitric oxide levels. CONCLUSION: We conclude that Maras powder has similar adverse effects on nitric oxide level and cardiovascular risk parameters and thereby it appears to be harmful as cigarette smoking.

BACKGROUND: There are controversial results regarding the endothelial function in patients with white coat hypertension (WCH). The aim of this study was to assess endothelial function measuring nitric oxide (NO) and C-reactive protein (CRP) level in WCH and to compare those with essential hypertension (EH) and healthy subjects. METHODS: The 40 newly diagnosed patients with EH, 40 patients with WCH and 40 healthy volunteers were included to study. Plasma CRP levels were measured by immunonephelometery method. Plasma NO level was also detected by using the Griess method. RESULTS: Plasma CRP level was significantly higher in patients with EH when compared with those with WCH and healthy subjects (6.3 ± 2.1 mg/l, 2.1 ± 0.9 mg/l and 1.6 ± 1.3 mg/l, p < 0.05, respectively). However, there was no significant difference with respect to CRP level between those with WCH and healthy subjects. NO level was significantly lower in patients with EH when compared with those with WCH and healthy subjects (4.6 ± 1.1 µmol/l, 6.9 ± 1.2 µmol/l and 8.1 ± 1.5 µmol/l, p < 0.05, respectively). There was no significant difference with respect to NO level between those with WCH and healthy subjects. Plasma CRP level was positively correlated with office, daytime, night-time and 24-h blood pressure values, whereas NO level was inversely correlated with these parameters. Plasma CRP level was also inversely correlated with NO level. CONCLUSIONS: Our data suggest that CRP concentration is significantly higher and NO level is meaningfully lower in patients with essential hypertension when compared with those with WCH and controls. This may suggest that endothelial functions are preserved in patients with WCH in contrast to essential hypertension.

Mortality from cardiovascular disease has been found to be increased in patients with systemic lupus erythematosus (SLE). Coronary flow reserve (CFR) measurement is used both to assess epicardial coronary arteries and to examine the integrity of coronary microvascular circulation. Oxidative stress, enhancing modification of plasma lipids, is also associated with atherosclerotic events in lupus patients. Impairment of CFR and TAS has been shown to be an early manifestation of coronary atherosclerosis. Forty patients with SLE and 33 healthy volunteers were included in this study. Echocardiographic examination included left ventricular myocardial velocity measurements and coronary flow reserve (CFR) measurement. Serum total antioxidant status levels (TAS) also were measured using TAS kit. Lateral myocardial early peak velocity (Em) and lateral Em/Am ratio did not differ between the groups, but lateral myocardial atrial peak velocity (Am) was significantly higher in SLE group than the control group. Baseline coronary diastolic peak flow velocity (DPFV) of left anterior descending was similar in both the groups. However, hyperemic DPFV and CFR (2.50 ± 0.42 vs. 3.09 ± 0.45, P < 0.0001) were significantly lower in the SLE group than in the control group. CFR significantly and inversely correlated with CRP and significantly correlated with TAS. Subclinical coronary microvascular dysfunction can occur in SLE patients without traditional cardiovascular risk factors, probably associated with underlying inflammation and impairment of TAS.

High-sensitivity C-reactive protein (CRP) has been shown to predict cardiovascular disease. Metabolic syndrome has been found to play a critical role in the development of cardiovascular disease. The purpose of this report is to assess the relationship between CRP and the metabolic syndrome. A total of 50 patients with metabolic syndrome and 40 healthy persons were included in the study. Plasma concentrations of CRP were measured by means of particle-enhanced immunonephelometry with the Behring nephelometer using N Latex CRP mono reagent. CRP levels were higher in patients with metabolic syndrome than control group (10.6 +/-5.4 mg/L vs 3.5 +/-0.8 mg/L, p<0.001). In partial correlation, plasma CRP positively correlated with body mass index (p<0.001), waist circumference (p<0.001), waist-to-hip ratio (p<0.01), total cholesterol (p<0.001), LDL-cholesterol (p=0.033), triglyceride (p=0.023), and fasting blood glucose (p=0.043) in patients with metabolic syndrome. HDL-cholesterol did not significantly correlate with CRP (p>0.05). In multiple regression analysis, body mass index (p<0.01), waist circumference (p<0.01), and fasting blood glucose (p<0.01) showed independent correlations with plasma CRP. CRP levels were found higher in patients with metabolic syndrome. These results suggest that abdominal obesity is the critical correlates of elevated plasma CRP levels found in patients with metabolic syndrome. These patients carrying high risk for cardiovascular events must be followed closely.

Clopidogrel is a new antiplatelet agent. To date, no case of a spontaneous abdominal hematoma during clopidogrel therapy has been reported. We report a case of a 70-year-old woman who developed a spontaneous abdominal hematoma following clopidogrel treatment. The patient has been suffering from a progressive swelling in the abdominal wall for 1-2 weeks and noticed a purple discoloration of the skin over the swelled abdominal region the week before hospitalization. There was a palpable mass in the right upper quadrant of the abdomen and ecchymoses surrounding the umbilicus. At abdominal ultrasonography, the mass was found to be consistent with the hematoma. The hematoma was drained under local anesthesia. The patient was discharged with no complication. She was advised to submit herself to regular physical examinations. Although adverse reactions are generally rare, we suggest that physicians prescribing clopidogrel should be aware of the possibility of this adverse reaction.

OBJECTIVE: A plant powder called "Maras Powder" has been used widely instead of cigarette in the South-Eastern region of Turkey. It was confirmed that this powder has been made of tobacco N. rustica L. Our aim was to investigate whether the use of Maras Powder is as harmful as cigarette smoking or not. METHODS: Forty-five Maras Powder users (Group I), 32 persons who smoked cigarette (control-Group II) and 30 healthy persons neither smoking nor using Maras Powder (Group III) were included into the study. Laboratory investigations, electrocardiography and echocardiography were performed in all participants of the study. For evaluation of the ventricular repolarization parameters, 50 mm/sec ECG recordings were used. Echocardiographic investigation was performed for assessment systolic and diastolic function. RESULTS: No differences were found by means of ventricular repolarization parameters among the three groups (p>0.05). Echocardiographic investigation revealed similar systolic function results in all of the three groups. There was reduced early filling velocity of the left ventricle (p=0.03, p=0.02) and increased filling velocity of the atrial component (p=0.02, p=0.02) in group I and group II. When they were compared to group III, deceleration time was also increased (p<0.01, p<0.01). Isovolumetric relaxation time was higher in group I and group II than that of group III (p=0.02, p=0.03). In group I and group II, total cholesterol (p=0.03, p=0.02), LDL-cholesterol (p<0.01, p<0.01) and triglyceride levels (p<0.01, p<0.01) were found to be higher than those of group III, whereas HDL levels were lower (p=0.02, p<0.01). CONCLUSION: As a result, we thought that Maras Powder is as harmful as cigarette smoking and it has similar negative effects on cardiovascular system. In our opinion, "Maras Powder" is a smokeless tobacco use.

Seventy one years old woman admitted to our clinic with the complaints of fever, cough and palpitation. Physical examination revealed a palpable thyroid with a 2 cm in length in its isthmus and large right lobe. Kyphotic patient was tachycardic. Other systems were within normal limits. Chest x-ray performed wide upper mediastinum with calcified nodule approximately 3.5 cm in dimension in the apex of the left lung. Computed tomography revealed thyroid gland lying through the upper mediastinum and a mass 3.5 x 3.2 cm in dimension in the left lobe inferior regio of the gland surrounded with calcification. Thyroid function tests showed hyperthyroidism. Clinically patient had a substernal multinodular goitre. Since the lesion demonstrating egg shell calcification at the apex of left lung in the chest roentgenogram belonged to substernal goitre, the case was accepted interesting and presented below.

BACKGROUND: The long-term results of coronary artery bypass surgery depend mostly on the type of the grafts. For a long time, it has been accepted that arterial grafts are superior to venous grafts. In this study, we evaluated the angiographic patency rates of arterial and venous grafts. METHODS: The study took place between 2003 and 2013 in the Departments of Cardiovascular Surgery in Baskent University. The study included 52 patients with recurrent ischemic symptoms (of total 2183 coronary artery bypass surgery patients) following coronary artery bypass surgery. The patients were evaluated by control angiography during over mid- and long-term postoperative period (mean, 75.25 ± 35.15 months). Based on the angiographic findings, the grafts were divided into 3 groups: severe stenosis, moderate stenosis, and patent. RESULTS: The preoperative demographics (age, gender, hypertension or diabetes mellitus) were similar in the three groups. The mean numbers of distal anastomoses were 3.27 ± 0.89 (range 2-5), the degree of native coronary artery stenosis for radial artery anastomosis was 79.65 ± 17.72, and the mean numbers of radial artery and saphenous vein grafts were 1.19 ± 0.44 and 1.10 ± 0.89, respectively. The patency rate was 80.77%for radial arteries, 63.2% for saphenous veins, and 82.4% for left internal thoracic arteries in the three groups. CONCLUSION: The internal thoracic artery graft was confirmed to be the best option for aorta-coronary bypass surgery, as it has the highest patency rate compared to the other grafts. Radial artery and saphenous vein patency rate were also seen to be similar in the long-term.

Morning blood pressure surge (MBPS) is defined as an excessive increase in blood pressure (BP) in the morning from the lowest systolic BP during sleep, and it has been reported as a risk factor for cardiovascular events in current clinical studies. In this study, we evaluated the association between the rate of BP variation derived from ambulatory BP monitoring data analysis and coronary microvascular function in patients with early stage hypertension. One hundred seventy patients with prehypertension and Stage 1 hypertension who fulfilled the inclusion and exclusion criteria were included in the study. We divided our study population into two subgroups according to the median value of coronary flow reserve (CFR). Patients with CFR values <2.5 were defined as the impaired CFR group, and patients with CFR values ≥2.5 were defined as the preserved CFR group, and we compared the MBPS measurements of these two subgroups. CFR was measured using transthoracic Doppler echocardiography (TTDE). Ambulatory 24-hour systolic and diastolic BP, uric acid, systolic MBPS amplitude, diastolic MBPS amplitude, high-sensitivity C-reactive protein, and mitral flow E/A ratio were statistically significant. These predictors were included in age- and gender-adjusted multivariate analysis; ambulatory 24-hour systolic BP (ß = 0.077, P < .001; odds ratio [OR] = 1.080; 95% confidence interval [CI] [1.037-1.124]) and systolic MBPS amplitude (ß = 0.043, P = .022; OR = 1.044; 95% CI [1.006-1.084]) were determined to be independent predictors of impaired CFR (Hosmer-Lemeshow test, P = .165, Nagelkerke's R(2) = 0.320). We found that increased changes in MBPS values in patients with prehypertension and Stage 1 hypertension seemed to cause microvascular dysfunction in the absence of obstructive coronary artery disease.
