RESUMO
OBJECTIVE: This study assessed whether high levels of iodide administered during percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) differentially influenced thyroid function compared to PCI for non-complex coronary lesions. SUBJECTS AND METHODS: A total of 615 patients were enrolled in the study; 205 underwent elective PCI for CTO lesions (Group I) and 410 underwent elective PCI for non-complex lesions including non-CTO, non-bifurcation, non-calcified, and non-tortuous lesions (Group II). Patients were monitored for development of incidental thyroid dysfunction between 1 and 6 months after PCI. RESULTS: The patients in Group I were administered a median of 255 mL of contrast medium during PCI for CTO; a median of 80 mL was administered to the patients in Group II during non-complex PCI (p =0.001). Ten (5.4%) of the 186 euthyroid patients in Group I and 19 (5%) of the 379 eu-thyroid patients in Group II developed subclinical hyper-thyroidism (p = 0.854). However, 7 (50%) of the 14 subclinical hyperthyroid patients in Group I and only 3 (12%) of the 25 subclinical hyperthyroid patients in Group II developed overt hyperthyroidism (p = 0.019). CONCLUSION: In euthyroid patients, PCI for coronary CTO lesions did not increase the risk for subclinical hyperthyroidism when compared to PCI for non-complex coronary lesions. However, in patients with subclinical hyperthyroidism at baseline, PCI for coronary CTO lesions significantly increased the development of overt hyperthyroidism when compared to PCI for non-complex coronary lesions.

AIM: Transradial access (TRA) for coronary intervention is increasingly used in current clinical practice. The aim of the present study was to evaluate the hypothesis that cutaneous analgesia before TRA for coronary intervention at a puncture site 30 minutes before puncture can reduce patient discomfort and the incidence of radial artery spasm (RAS). METHODS: Patients (n=104) undergoing planned coronary interventions using TRA were prospectively randomized to receive either 1 mL of 1% lidocaine subcutaneously (n=52) (control group) or subcutaneous lidocaine plus 5% lidocaine cream (n=52) cutaneously 30 minutes before puncture (treatment group). The primary endpoint was angiographically or clinically confirmed RAS. Secondary endpoints were the occurrence of patient discomfort in the forearm during the procedure and access-site crossover to the femoral artery. Patient discomfort was quantified with a visual analogue scale (VAS) score. RESULTS: Fifty-two patients in the treatment group (60.5±9.4 years of age and 16 female) and 52 patients in the control group (60.4±9.7 years of age and 16 female) were included in the final analysis. Radial artery spasm occurrence decreased in the treatment group compared to the control group (26.9% vs 9.6%; p=0.04) accompanied by a VAS score of 3.7±1.8 in the treatment group and 4.9±2.0 in the control group; p=0.02. The access site crossover rate did not differ between the groups (7.6% vs 21.1%; p=0.09). CONCLUSION: Cutaneous analgesia before TRA for coronary interventions is associated with a substantial reduction in the RAS and the procedure-related level of patient discomfort.

OBJECTIVE: The aim of this study was to evaluate the left (LV) and right (RV) ventricular function in euthyroid Hashimoto's thyroiditis (eHT) patients. SUBJECTS AND METHODS: Forty-five patients diagnosed with eHT and 45 age- and gender-matched control subjects were enrolled in this study. Echocardiographic parameters reflecting RV and LV functions such as chamber dimensions, ejection fraction, fractional shortening, conventional and tissue Doppler-derived early and late filling velocities (E, A, E', A'), isovolumic relaxation (IVRT) and contraction (IVCT) times, ejection time (ET), deceleration time (DT), Tei index, pulmonary acceleration time (PAcT) and tricuspid annular plane systolic excursion (TAPSE) of patients with eHT were compared to those of control subjects using the paired-samples t test or Wilcoxon signed-rank test. RESULTS: Regarding the LV function, compared to the controls patients with eHT had a higher LV-Tei index (0.6 ± 0.2 vs. 0.4 ± 0.1, p < 0.001), higher DT (p < 0.001) and IVRT (p < 0.001) values, and higher E/E' ratios (p = 0.04). In contrast, the peak E wave velocity (p = 0.02), E/A ratio (p = 0.01) and ET (p = 0.02) were significantly lower in the eHT group than amongst the controls. The RV, Tei index (0.40 ± 0.11 vs. 0.28 ± 0.07, p < 0.001), TAPSE (2.0 ± 0.3 vs. 2.2 ± 0.2 mm, p < 0.001), PAcT (124.3 ± 22.6 vs. 149.4 ± 18.3 ms, p < 0.001), A' (p = 0.007) and IVCT (p = 0.001) were significantly higher in patients with eHT than the controls. However, the tricuspid E/A ratio (p = 0.01), E' (p = 0.03) and E'/A' ratio (p = 0.001) were significantly lower in the eHT patients than the control group. CONCLUSIONS: This study demonstrated that both RV and LV functions were impaired in patients with eHT.

OBJECTIVES: Patients with carotid disease are frequently referred for carotid artery stenting based on the results of carotid duplex studies. During carotid artery stenting, the stent is usually extended into the common carotid artery, thereby crossing the external carotid artery. Previous studies have shown conflicting results regarding internal carotid stenting and external carotid artery flow velocities, but the effect of stenting on ipsilateral superior thyroid artery velocities has not been defined. This study examined the effect of internal carotid angioplasty and stenting on the ipsilateral superior thyroid artery Doppler-derived flow parameters. METHODS: We prospectively studied preinterventional and postinterventional duplex scans obtained from 41 patients (mean age ± SD, 64 ± 10 years) who underwent carotid artery stenting. The Doppler-defined preprocedural peak systolic velocity (PSV) end-diastolic velocity (EDV), resistive index (RI), and pulsatility index (PI) in the ipsilateral external carotid and superior thyroid arteries were compared with postprocedural values. RESULTS: Among patients with stenting, the preprocedural PSV, EDV, RI, and PI in the ipsilateral superior thyroid artery were 30 ± 11 cm/s, 13 ± 6 cm/s, 0.62 ± 0.11, and 1.04 ± 0.28,respectively; after stenting, they were 36 ± 8 cm/s, 14 ± 9 cm/s, 0.71 ± 0.07, and 1.11 ± 0.19. The preprocedural PSV, EDV, RI, and PI in the ipsilateral external carotid artery were 79 ± 24 cm/s, 17 ± 7 cm/s, 0.77 ± 0.26, and 1.27 ± 0.22; after stenting, they were 94 ± 31 cm/s, 20 ± 6 cm/s, 0.80 ± 0.4, and 1.25 ± 0.31. Despite a slight increase in superior thyroid and external carotid artery flow, there was no statistically significant change from before to after stenting. CONCLUSIONS: This study showed no differences in blood velocity profiles in the ipsilateral superior thyroid and external carotid arteries after stenting.

BACKGROUND: We have known that patients with renal insufficiency (creatinine level) have increased mortality for coronary artery disease. In this study, the relationship between admission creatinine level and one year mortality are evaluated in patients with acute myocardial infarction (AMI). METHOD: 160 AMI patients (127 men and 33 women with a mean age of 59 ± 13) were enrolled in the study. Serum creatinine levels were measured within 12 hours of AMI. The patients were divided into two groups according to admission serum creatinine level. (1) elevated group (serum creatinine > 1.3 mg/dL) and (2) normal group (≤1.3 mg/dL). One year mortality rates were evaluated. RESULTS: Elevated serum creatinine is observed in the 27 patients (16.9%). The mean creatinine level is 1.78 ± 7 mg/dL in the elevated group and 0.9 ± 0.18 mg/dL in the normal group (P < 0.0001). The mortality rate of the elevated group (n = 7, 25.9%) is higher than that of the normal group (n = 9, 6.8%). A significant increase in one year mortality is also observed (P=002) 60. CONCLUSION: The mildly elevated admission serum creatinine levels are markedly increased to one year mortality in patients with AMI.

Sildenafil was the first oral compound to be approved for the treatment of erectile dysfunction. It is a selective inhibitor of isoform 5 of phosphodiesterase, which is the enzyme responsible for the breakdown of 3', 5'-cyclic guanosine mono-phosphate. Sildenafil-associated myocardial infarction (MI) is rarely seen in patients without previous history of coronary artery disease. A 43-year-old man presented with sudden onset of chest pain. It was determined that his chest pain started after sildenafil intake. Findings consistent with acute anterior MI were observed on electrocardiography. Coronary angiography showed total occlusion of left anterior descending artery with thrombosis. Coronary angioplasty and stenting was successfully performed.

OBJECTIVES: Increased homocysteine (HCY) levels are associated with an increased risk of cardiovascular disease. Plasma HCY is increased in chronic heart failure (CHF) patients, and previous studies suggest that hyperhomocysteinemia causes adverse cardiac remodeling and affects pump function. We aimed to evaluate the HCY levels in patients with diastolic heart failure with preserved left ventricular ejection fraction (LVEF). METHODS: We prospectively studied 68 patients (39 females and 29 males) who were hospitalized for symptomatic heart failure, as well as 40 age- and sex-matched healthy subjects who comprised the control group. CHF was diagnosed in all cases based on Framingham diagnostic criteria. CHF with preserved LVEF was defined as cases with CHF with an LVEF of 50% or more. Patients with regional left ventricular wall motion abnormalities, atrial fibrillation, and renal failure were excluded. RESULTS: The mean age was 65.5 ± 9.6 years in the heart failure group and 65.2 ± 9.7 years in the control group. The mean LVEF was 59.8 ± 5.3 in the heart failure group and 61.4 ± 5.2 in the control group. The mean total fasting HCY concentrations were significantly higher in patients with heart failure (16.9 ± 5.27 µmol/l vs. 10.15 ± 3.49 µmol/l, respectively; p < 0.001). Multiple regression analysis indicated that NT-proBNP, hs-CRP, E/A ratio, and HbA1C were independently associated with hyperhomocysteinemia. CONCLUSIONS: Our results suggest that hyperhomocysteinemia is prevalent in heart failure with preserved ejection fraction. Larger scale studies are needed to clarify its pathogenic mechanisms and effects on the natural history of heart failure.

OBJECTIVE: The use of the radial approach in coronary angiography or percutaneous coronary intervention has increased owing to its advantages over the femoral approach such as rapid patient mobilization and improved patient comfort. However, radial artery spasm (RAS) that occurs during the procedure is a crucial factor in transradial approach failure and access site switch. Asymmetric dimethylarginine (ADMA) is a naturally occurring, modified amino acid that inhibits nitric oxide (NO) production. High ADMA levels may reduce arterial elasticity especially in small arteries like the radial artery. This study aimed to evaluate the relationship between ADMA levels and RAS in radial artery access. METHODS: This study included 155 patients (89 males and 66 females) who underwent transradial coronary angiography between January 2016 and June 2016. The ADMA level in the plasma was determined using a quantitative sandwich enzyme immunoassay technique. RESULTS: RAS was observed in 16 of the 155 patients (10.1%). The RAS was found to be more frequent in female patients (17.9% for women vs. 4.4% for men, p=0.019). The plasma concentration of ADMA in the RAS group was significantly higher than that in the control group [22.1 ng/mL (12.1-37.8) vs. 9.2 ng/mL (5.9-14.8), p<0.001]. Moreover, the plasma concentration of ADMA was significantly higher in patients with RAS among female patients [20.4 ng/mL (12.1-44.9) vs. 9.9 ng/mL (6.2-16.6); p=0.002] and among male patients [25.2 ng/mL (13.7-35.4) vs. 8.2 ng/mL (5.9-12.8); p=0.007]. Binary logistic regression analysis of all patients showed that ADMA concentration was the only predictor for RAS (odds ratio=1.142; 95% confidence interval=1.061-1.228; p<0.001). CONCLUSION: It was found that the ADMA concentration of the patients in the RAS group was elevated compared to that of controls. The findings indicated that elevated ADMA concentrations could predict RAS that may occur.

OBJECTIVE: Heart failure is frequently a serious complication of acute myocardial infarction (AMI). ACE inhibitors, Angiotensin II receptor blockers, beta-blockers and aldosterone receptor blockers have been shown to improve outcomes in this setting. This study aimed to determine the effect of spironolactone on the frequency of clinical heart failure, mortality, rehospitalization and left ventricular functions determined by echocardiography. MATERIAL AND METHODS: A total of 82 patients with STEMI hospitalized within 6-12 h of debut of symptoms were included in the study. The patients were randomly assigned into spironolactone (group A) or placebo (group B) groups after informed consent had been obtained. RESULTS: All patients were followed for 6 months. There were no statistically significant differences between the two groups when demographic criteria were compared. The incidence of post-MI angina pectoris, rhythm and conduction disturbance during hospitalization was significantly higher in Group B than in Group A. Although not statistically significant, the incidence of clinical heart failure was slightly lower in Group A than in Group B (5% versus 11%). Left ventricular end-diastolic volumes were slightly lower in Group A than in Group B, although statistically this was not significant. CONCLUSIONS: In concordance with these findings, the ejection fraction was slightly higher in Group A than in Group B, although this was not statistically significant (47% versus 44%). This trend continued during a 6-month follow-up after randomization. Our findings suggest that early administration of aldosterone blockers provides additional benefits after AMI, reducing the incidence of post-MI angina pectoris and rhythm and conduction disturbances.

BACKGROUND: There are many well-known causes of pericardial effusion, such as cancer metastasis, bacterial or viral pericarditis, and uremic pericarditis; however, no reports exist in the literature demonstrating a pericardial effusion that led to cardiac tamponade following consumption of an herbal remedy. CASE REPORT: A 32-year-old male patient was referred to our cardiology outpatient clinic with a complaint of dyspnea. The patient's medical history was unremarkable; however, he had consumed 3 boxes of horse chestnut (Aesculus hippocastanum L) paste over the previous 1.5 months. His chest x-ray examination revealed an enlarged cardiac shadow and bilateral pleural effusion. On transthoracic echocardiographic examination, his ejection fraction was found to be 55% with circumferentially extended pericardial effusion that reached 3.9 cm at its maximal thickness. No growth had been detected in the pericardial and pleural biopsies or blood samples; there was no evidence of an infectious process in the physical examination. Based on this information, we diagnosed pericarditis resulting from the use of herbal remedies. This is the first report to demonstrate that herbal remedy consumption may cause this type of clinical condition. CONCLUSIONS: Besides other well-known causes, pericardial effusion related to the consumption of herbal remedies should always be considered when treating patients with pericardial effusion caused by unclear etiologies.

Polymorphisms in Lys939Gln XPC gene may diminish DNA repair capacity, eventually increasing the risk of carcinogenesis. The aim of the present study was to evaluate the significance of polymorphism Lys939Gln in XPC gene in patients with mitral chordae tendinea rupture (MCTR). Twenty-one patients with MCTR and thirty-seven age and sex matched controls were enrolled in the study. Genotyping of XPC gene Lys939Gln polymorphism was carried out using polymerase chain reaction- (PCR-) restriction fragment length polymorphism (RFLP). The frequencies of the heterozygote genotype (Lys/Gln-AC) and homozygote genotype (Gln/Gln-CC) were significantly different in MCTR as compared to control group, respectively (52.4% versus 43.2%, p = 0.049; 38.15% versus 16.2%, p = 0.018). Homozygote variant (Gln/Gln) genotype was significantly associated with increased risk of MCTR (OR = 2.059; 95% CI: 1.097-3.863; p = 0.018). Heterozygote variant (Lys/Gln) genotype was also highly significantly associated with increased risk of MCTR (OR = 1.489; 95% CI: 1.041-2.129; p = 0.049). The variant allele C was found to be significantly associated with MCTR (OR = 1.481; 95% CI: 1.101-1.992; p = 0.011). This study has demonstrated the association of XPC gene Lys939Gln polymorphism with MCTR, which is significantly associated with increased risk of MCTR.

BACKGROUND: CHA2DS2-VASc score is the most widely preferred method for prediction of stroke risk in patients with atrial fibrillation. We hypothesized that CHA2DS2-VASc score may represent atrial remodeling status, and therefore echocardiographic evaluation of left atrial electromechanical remodeling can be used to identify patients with high risk. METHODS: A total of 65 patients who had documented diagnosis of paroxysmal atrial fibrillation (PAF) were divided into three risk groups according to the CHA2DS2-VASc score: patients with low risk (score=0, group 1), with moderate risk (score=1, group 2), and with high risk score (score ≥2, group 3). We compared groups according to atrial electromechanical intervals and left atrium mechanical functions. RESULTS: Atrial electromechanical intervals including inter-atrial and intra-atrial electromechanical delay were not different between groups. However, parameters reflecting atrial mechanical functions including LA phasic volumes (Vmax, Vmin and Vp) were significantly higher in groups 2 and 3 compared with group 1. Likewise, LA passive emptying volume (LATEV) in the groups 2 and 3 was significantly higher than low-risk group (14.12±8.13ml/m(2), 22.36±8.78ml/m(2), 22.89±7.23ml/m(2), p: 0.031). Univariate analysis demonstrated that Vmax, Vmin and Vp were significantly correlated with CHA2DS2-VASc score (r=0.428, r=0.456, r=0.451 and p<0.001). Also, LATEV (r=0.397, p=0.016) and LA active emptying volume (LAAEV) (r=0.281, p=0.023) were positively correlated with CHA2DS2-VASc score. In the ROC analysis, Vmin≥11ml/m(2) has the highest predictive value for CHA2DS2-VASc score ≥2 (88% sensitivity and 89% specificity; ROC area 0.88, p<0.001, CI [0.76-0.99]). CONCLUSION: Echocardiographic evaluation of left atrial electromechanical function might represent a useful method to identify patients with high risk.

BACKGROUND: Patients with non-ST-elevation acute coronary syndrome are heterogeneous in terms of clinical presentation and immediate- and long-term risk of death or non-fatal ischemic events. The aim of the present study was to evaluate the relationship between the Global Registry of Acute Coronary Events (GRACE) score and severity of coronary artery disease angiographically evaluated by Gensini score in patients with non-ST-elevation acute coronary syndrome. METHODS: A total of 245 patients with non-ST-elevation acute coronary syndrome were enrolled to the study. Based on the GRACE risk score classification system, the patients were divided into low- (n=97, 39.6%), intermediate- (n=84, 34.3%), and high- (n=64, 26.1%) risk groups. All patients underwent coronary angiography within five days after admission. RESULTS: The Gensini scores were 26±29 in the low-risk group, 29±19 in the intermediate-risk group, and 38±23 in the high-risk group (p=0.016). The low-risk group was significantly different from the high-risk group (p=0.013), and the difference from the intermediate-risk group almost reached significance. Normal, noncritical, one and two, or multivessel disease were identified in 15 (6.1%), 31 (12.7%), 75 (30.6%), and 124 (50.6%) patients, respectively. The prevalence of multivessel disease was 28% in the low-risk group, 30% in the intermediate-risk group, and 42% in the high-risk group. The high-risk group was significantly different from the low-risk group (p<0.01). CONCLUSION: Our study demonstrates that the GRACE score has significant value for assessing the severity and extent of coronary artery stenosis in patients with non-ST-elevation acute coronary syndrome.

Drowning is one of the fatal accidents frequently encountered during the summer and is the most common cause of accidental death in the world. Anoxia, hypothermia, and metabolic acidosis are mainly responsible for morbidty. Cardiovascular effects may occur secondary to hypoxia and hypothermia. Atrial fibrillation, sinus dysrhythmias (rarely requiring treatment), and, in serious cases, ventricular fibrillation or asystole may develop, showing as rhythm problems on electrocardiogram and Osborn wave can be seen, especially during hypothermia. A 16-year-old male patient who was admitted to our hospital's emergency service with drowning is presented in this article. In our case, ventricular fibrillation and giant J wave (Osborn wave) associated with hypothermia developed after drowning was seen. We present this case as a reminder of ECG changes due to hypothermia that develop after drowning. Response to cardiopulmonary resuscitation after drowning and hypothermia is not very good. Mortality is very high, so early resuscitation and aggressive treatment of cardiovascular and respiratory problems are important for life.
RESUMO
Central venous catheterisation allows delivery of medications, intravenous fluids, parenteral nutrition, haemodialysis and monitoring of haemodynamic variables. Various complications may occur during and after the procedure. However, the complete guidewire retention has rarely been reported. In this report, we have presented a complete guidewire retention as a result of inadvertent catheter insertion. After 17 months of the first operation performed upon the diagnosis of Fournier's gangrene, the patient was admitted to the cardiology polyclinic with a recurrent chest pain. Echocardiography showed a wire-shaped foreign body within the right part of the heart, and a fluoroscopic examination showed a guidewire reaching from the superior vena cava to the right external iliac vein. In retrospect, the wire was already visible on the postoperative chest x-rays and CT taken while the patient was still in intensive care unit, but its presence was overlooked at that time. The guidewire was retrieved completely during a surgery.

Clopidogrel is an oral antiplatelet agent used in the treatment of coronary artery disease, peripheral vascular disease and cerebrovascular disease. Gastrointestinal symptoms including nausea, diarrhea and constipation are the common side effects of this drug. Serious side effects like intracranial hemorrhage and severe neutropenia were also reported but spontaneous pectoral hematoma due to the clopidogrel has not been reported previously. We present a case of large spontaneous pectoral hematoma during clopidogrel therapy in an elderly woman.

OBJECTIVE: The effects of coronary artery bypass grafting (CABG) on mortality have not been evaluated in patients with well-developed coronary collaterals. We investigated functional capacity, presence of angina, the occurrence of acute myocardial infarction, survival and mortality in patients with well-developed coronary collaterals both undergoing and refusing CABG. METHODS: The study was designed as a retrospective observational case-controlled study. Seventy-eight patients undergoing coronary angiography were included in this study. They had critical occlusion in the proximal left anterior descending artery (LAD) with Rentrop-3 collateral circulation towards LAD, and to proceed with CABG has been suggested. The patients were divided in two groups; first group proceeding with CABG (n=40) and the second, rejecting the surgery (medical treatment group; n=38). The rates of survival, the incidence of angina pectoris and acute myocardial infarction as well as the functional capacities were evaluated in all patients. Survival rates were evaluated using Kaplan-Meier survival analysis. RESULTS: No statistically significant difference was observed between the two groups regarding the baseline characteristics of patients, the presence of angina pectoris, the severity of angina pectoris according to CCS, the occurrence of acute myocardial infarction or stroke, and the functional capacity according to NYHA (p>0.05). Death due to cardiovascular reasons was observed in eight patients of CABG group and in five patients of medical treatment group (p=0.710). The 5-year survival rate was observed to be 80% in CABG group while it was observed to be 84% in the medical treatment group (p=0.730). CONCLUSION: There was no significant difference regarding the survival rates in patients with well-developed coronary collaterals proceeding with CABG or medical treatment.
