RESUMEN

The aloe vera plant has become increasingly popular in recent years. This study aimed to research the effect of aloe vera to prevent renal and lung tissue damage in an experimental ischemia-reperfusion (I/R) injury model. The study included 21 male Wistar Albino rats, which were categorized into control group, n = 7 (no procedures), Sham group n = 7 (I/R); and aloe vera therapy group, n = 7 (aloe vera and I/R). Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and malondialdehyde (MDA) were evaluated from lung and kidney tissues for biochemical investigations. As histopathological, hematoxylin and eosin and anti-iNOS were also examined. In biochemical investigations, SOD, CAT, and GPx levels of the Sham group were found to be lower compared with the other groups (P < 0.05). The aloe vera therapy group was not statistically different from control groups but significantly different compared with the Sham group. In the same way, the MDA levels of kidney and lung tissues were statistically significant in the aloe vera therapy group, compared to the Sham group. In the Sham group, the peribronchial and perialveolar edema were observed in lung parenchyma. Also, excess interstitial hemorrhage, leukocyte infiltration, and alveolar wall thickening were identified in ischemic groups. The histopathological changes were much lighter than in the aloe vera therapy group. In renal tissues, excess epithelial cell deterioration, tubular desqumination, and glomerular atrophy were observed in the Sham group. The histopathological changes were markedly reduced in the aloe vera therapy  group. In the kidney and lung tissue, the level of iNOS activity in the Sham group was significantly higher than in the control and aloe vera therapy group. This study indicated that aloe vera is protective against oxidative damage formed by I/R in distant organs like the lungs and kidneys.

RESUMEN

BACKGROUND: Infective endocarditis, a disease with high mortality and morbidity, is most commonly caused by Staphylococcus aureus; mortality and morbidity further increase in the presence of methicillin-resistant strains of S. aureus. Linezolid is the first of the oxazolidinones, a new antibiotic group that has been approved for the treatment of infections caused by gram-positive cocci. Linezolid reduces the quantity of microorganisms in vegetation to some extent; in addition, the use of hyperbaric oxygen (HBO) and ozone (O3) therapies is likely to improve targeted antibacterial effect. MATERIALS AND METHODS: Fifty-six adult male Wistar rats weighing 300-350 g were used. The subjects were divided into groups as follows: Group 1 (n = 8): control group that was not inoculated with microorganisms and was untreated; Group 2 (n = 8): control group that was inoculated with microorganisms but was untreated; Group 3 (n = 8): linezolid treatment group; Group 4 (n = 8): O3 therapy group; Group 5 (n = 8): HBO therapy group; Group 6 (n = 8): linezolid + O3 therapy group; Group 7 (n = 8): linezolid + HBO therapy group. RESULTS: In terms of reducing the number of colonies in the aortic valve, linezolid + HBO therapy was found to be the most effective treatment. Then, respectively linezolid + O3, linezolid, HBO, and O3 were found to be effective. CONCLUSIONS: We found that linezolid significantly reduced the number of bacteria in the vegetation in the experimental endocarditis model, and HBO therapy increases the effectiveness of linezolid and makes this better than O3.

RESUMEN

Posttraumatic arteriovenous fistulas (AVFs) are common complications of vascular penetrating trauma. Here we present a case of a 59-year-old woman who had a history of gunshot injury 42 years ago causing AVF between superficial femoral artery (SFA) and superficial femoral vein (SFV). SFV was resected. Ipsilateral SFA was used to restore SFV. SFA was reconstituted using a 7-mm polytetrafluorethylene graft. The patient has normal venous and arterial flow at 3- and 15-month follow-up.

RESUMEN

PURPOSE: Coronary slow flow (CSF) is a rare condition described as the delayed angiographic passage of a contrast agent in the absence of stenosis in epicardial coronary arteries. Left ventricular (LV) systolic and diastolic dysfunctions have been described in the presence of CSF. However, the effect of CSF on LV twist functions has not been assessed. We aimed to evaluate the effects of CSF on LV twist mechanics using speckle tracking echocardiography (STE). METHODS: Twenty CSF patients (24-60 years) were enrolled according to the exclusion criteria. Twenty subjects with similar demographic characteristics and normal coronary arteries were the controls. Participants were evaluated with conventional echocardiography and STE. RESULTS: The general characteristics of the two groups were similar. LV twist, LV torsion, and apical rotation were impaired in the CSF group (P = 0.015, P = 0.012, and P < 0.001, respectively). Time to peak twist (TPT) and time to peak untwisting (TPU) were prolonged in CSF patients (P < 0.001 and P < 0.001, respectively). In the CSF group, rotation-deformation delay was shortened (P < 0.001) and global longitudinal strain (GLS) was lower (P < 0.001). The thrombolysis in myocardial infarction (TIMI) frame count was negatively correlated with LV twist, LV torsion and apical rotation (P = 0.002, r = -0.624; P = 0.002, r = -0.624; and P = 0.002, r = -0.632, respectively). CONCLUSIONS: We demonstrated that LV twist mechanics are impaired in CSF patients. Worse LV twist parameters were associated with greater TIMI frame count.

RESUMEN

INTRODUCTION: In this study, we aimed to reveal the normal anatomy and variations of the bronchial arterial system and to determine the sex distribution of these variations by retrospectively reviewing the images of patients who underwent thoracal multidetector computed tomographic angiography for various reasons. MATERIALS AND METHODS: Multidetector computed tomographic images of a total of 208 patients (151 men; mean age, 59 years) were retrospectively reviewed to assess the normal anatomy and variations of the bronchial arterial system. RESULTS: A total of 531 bronchial arteries (median, 3; minimum, 1; maximum, 5; mean, 2.5) were detected. The number (mean diameter) of the right bronchial arteries were higher than the left bronchial arteries (290 [1.43 mm] and 241 [1.26 mm], respectively; P < .05 for both number and diameter). The mean number (diameter) of the bronchial arteries were higher with men than with women (2.58 [1.45 mm] and 2.47 [1.32 mm], respectively; P < .05 for both number and diameter). The most common (24%) branching pattern was the combination of 1 right intercostal-bronchial trunk and 1 left bronchial artery, and, secondarily (13.46%), the combination of 2 right (1 intercostal-bronchial trunk and 1 bronchial artery) and 1 left bronchial arteries. Seventy-eight ectopic bronchial arteries were detected in 59 cases (28.3%). They most commonly originated from the aortic arch (37.2%), the descending aorta below the level of T6 (35.9%), or the aortic branches (16.7%). The number of right ectopic bronchial arteries was significantly higher than the left ectopic bronchial arteries (50 [64%] vs 28 [36%]; P < .01). The incidence of ectopic bronchial arteries was statistically higher with men versus women (45 [29.8%] vs 14 [24.6%]; P < .05). CONCLUSION: The origins, numbers, diameters, and courses of the bronchial arteries can vary substantially among individuals. Multidetector computed tomographic angiography enables a detailed road map of the bronchial arterial system to interventional radiologists and thoracic surgeons.

RESUMEN

Since the first successful application of the heart-lung machine in 1953 by John Gibbon [1], great efforts have been made to modify the bypass techniques and devices in order to allow prolonged extracorporeal circulation in the intensive care unit (ICU), commonly referred to as extracorporeal membrane oxygenation (ECMO). ECMO uses classic cardiopulmonary bypass technology to support circulation. It provides continuous, non-pulsatile cardiac output and extracorporeal oxygenation [2]. Veno-venous ECMO (VV ECMO) provides respiratory support, while veno-arterial ECMO (VA ECMO) provides cardio-respiratory support to patients with severe but potentially reversible cardiac or respiratory deterioration refractory to standard therapeutic modalities. ECMO is a temporary form of life support providing a prolonged biventricular circulatory and pulmonary support for patients experiencing both pulmonary and cardiac failure unresponsive to conventional therapy. Despite the advent of newer ventricular assist devices that are more suitable for long term support, ECMO is simple to establish, cost-effective to operate.

RESUMEN

OBJECTIVE: Atrial septal defect is one of the most commonly encountered congenital heart diseases in adults. The effect of age of the patient to the surgery is disputable. The purpose of this report was to evaluate surgical repair in patients with ASD who are operated in our clinic. METHODS: Total 40 patients were subjected to surgical repair due to ASD in Van Yuksek Ihtisas Education and Research Hospital between February 2006 and April 2009. Twenty seven of the patients were female and 13 were male, their ages differed between 8 and 71 and mean age of the patients was 33.70±14.04. RESULT: Operative mortality did not occur. Two of our patients had coronary arterial disease in addition to ASD. ASD repair was performed together with coronary bypass surgery. Closing of ASD resulted in an increase in left ventricular ejection fraction, and a decrease in pulmonary arterial pressure and cardiothoracic ratio. Recovery in the functional capacity was observed post-surgery according to NYHA. CONCLUSION: In this series, surgical results of the patients of various ages, with ASD closed were positive.

RESUMEN

OBJECTIVE: Early and medium-term improvement of functional capacity and regression of left ventricular hypertrophy was evaluated in the young adult patient group following application of 21 mm or 23 mm bileaflet aortic mechanical valve prosthesis due to aortic stenosis. Methods : Twenty two patients (10 male, 12 female; mean age 27+-8.2 (19-43)) who underwent isolated aortic valve replacement due to rheumatic aortic stenosis, were included in the study. 21 mm and 23 mm bileaflet mechanical prosthesis was used respectively in eight and fourteen patients. The mean body surface area was 1.86 m(2) and 1.68 m(2) respectively in 23 mm and 21 mm prosthesis while 1.73 ±0.25 m(2) for the whole group. Functional capacity was New York Heart Association (NYHA) class II in 9 patients and class III in thirteen patients. Implantation was performed without enlarging the aortic root in all except four patients. In all patients transvalvular gradients, effective orifice area and the diameter of left ventricle were measured with transthoracic echocardiography during rest and after maximal exercise. Mean follow-up was 34±12 months (range 11-57 months). RESULTS: There were no postoperative complications or deaths. All the patients were assessed as NYHA class I with regards to functional capacity (p=0.01). Significant improvements were determined in postoperative mean transvalvular gradient (p=0.005) and left ventricular mass index (p=0.01) when compared with preoperative values. CONCLUSION: Our findings show that replacement with 21 mm and 23 mm mechanical prosthesis provides a significant improvement in regression of symptoms and increase of functional capacity in young adults in early and mid-period without increasing mortality and morbidity.

RESUMEN

OBJECTIVE: Prior studies have demonstrated the relationship between cardiovascular diseases and fragmented QRS (fQRS). fQRS was also associated with ventricular arrhythmias. Our objective was to find out the relationship between fQRS and paroxysmal atrial fibrillation (PAF). METHOD: A total of 301 patients without overt structural heart disease were prospectively included in the study. Patients were divided in to 2 groups according to presence of fQRS. Multivariate logistic regression analysis was used to assess the predictive value of fQRS for predicting PAF. RESULTS: One hundred and three patients had fQRS. Patients with fQRS were older (53±16.8 vs 45.3±17.2, p<0.001), with larger left atrium (LA) (33.2±5.9 vs 30.1±5.9 mm, p=0.001), with thicker interventricular septum (IVS) (10.2±1.9 vs 9.5±2.3 mm, p=0.032), more diabetic (19.8 vs 10.6%, p=0.029) and have more PAF episodes (22.3 vs 4.1%, p<0.001) in comparison with patients without fQRS. fQRS was an independent predictor of detecting PAF episode (odds ratio, 9.69; 95% confidence interval, 2.46-38.15, p=0.001). Hypertension and diabetes mellitus were also predictive. CONCLUSION: The presence of fQRS independently predicted PAF episodes in holter monitoring (HM). Further studies are needed to clarify the clinical implications of this finding.

RESUMEN

OBJECTIVES: Uric acid (UA) is a strong marker of cardiovascular disease. Therefore, we aimed to determine the relationship between serum UA levels and cardiovascular events in patients in the early period of their acute myocardial infarction. STUDY DESIGN: This retrospective study included 586 consecutive patients with ST-elevated myocardial infarction (STEMI) who were admitted to the hospital between March 2010 and February 2012. The study population was divided into two groups; the first group included hyperuricemic patients (n=107; uric acid level >6 mg/dl in women and >7 mg/dl in men), and the second group included patients with normal UA level (n=479). Multivariate analysis was used to demonstrate the predictive value of UA levels in groups. RESULTS: Patients in the hyperuricemic group were older (median 66 years vs. 60 years, p=0.001), and the ratio of female patients was higher (35.5% vs. 16.9%, p=0.001). Patients with hyperuricemia had a significantly higher incidence of in-hospital cardiovascular mortality than the normal group (15.9% vs. 3.1%, p<0.001). Advanced heart failure (class ≥ 3) was more frequent among hyperuricemic patients (17.8% vs. 8.8%, p=0.006). Age ≥ 70 years, chest pain duration >6 hours and hyperuricemia (hazard ratio (HR): 1.83, 95% confidence interval: 1.02-3.27; p=0.041) were found to be independent predictors of advanced heart failure. Hyperuricemia was found to be an independent predictor of in-hospital cardiovascular mortality in multivariate analyses (HR: 5.32, 95% confidence interval: 2.46-11.49; p=0.001). CONCLUSION: This study showed that a high serum UA level is an independent predictor of cardiovascular mortality and morbidity during the in-hospital period of STEMI.

RESUMEN

This study aimed to investigate the effects of pharmacomechanical thrombectomy on novel complete blood count parameters in deep venous thrombosis. This retrospective study included 242 patients aged >18 years who were treated for deep venous thrombosis. Patients were grouped as follows: group 1 was accepted as having interventional operations (n = 123) and group 2 was accepted as having only medical advice (n = 119). Routine complete blood count parameters, the neutrophil-to-lymphocyte ratio (NLR), and the platelet-to-lymphocyte ratio (PLR) were compared. There was no difference between the groups in terms of admission hemoglobin, hematocrit, mean platelet volume, NLR and PLR (P = .11, P = .24, P = .55, P = .93, and P = .96, respectively). In the pharmacomechanic thrombectomy group, NLR and PLR were significantly reduced after intervention when compared to the admission values (P < .001 and P < .001, respectively). However, the NLR and PLR values of medically treated patients did not differ significantly from their baseline values (P = .16 and P = .08, respectively). In this study, we effectively removed the thrombus load in blocked proximal veins using pharmacomechanical thrombectomy and observed a significant decrease in NLR and PLR, which are current, inexpensive, and accessible parameters.

RESUMEN

The hammock mitral valve is a rare congenital abnormality resulting in mitral regurgitation or stenosis, with incidences ranging from 0% to 12% in pediatric surgical series. It is difficult to correct this condition by reconstructive techniques. We describe here an alone hammock valve without any cardiac malformation in a five-year-old patient who underwent mitral valve replacement.

RESUMEN

OBJECTIVE: Paradoxical septal motion (PSM) can cause confusion in the assessment of ventricular function with scintigraphy even in the absence of ventricular septal damage and ischemia. Fragmented QRS (fQRS) is associated with various cardiac disorders. In this study, we aimed to determine the correlation between paradoxical septal motion and fQRS after coronary artery bypass grafting (CABG). METHODS: We retrospectively reviewed the hospital records showing scintigraphic images and electrocardiograms (ECG) of the patients who had undergone CABG. The patients were classified based on the evaluation of motion and thickening of the septal wall. The patients with regular thickening of the septal wall and abnormal motion were classified as PSM (+) group. The patients with normal motion and thickening of the septal wall were classified as PSM (-) group. fQRS complexes are defined as various RSR patterns either with or without Q-waves on a 12-lead resting ECG. RESULTS: PSM was found to be more common in fQRS patients (p < 0.001). PSM was seen in 91.4 % of cases with fQRS and in 79.8 % of cases without fQRS. No significant differences were found in the phase analysis parameters. A correlation was found between septal wall motion values and the presence of fQRS (r = 0.197, p = 0.012). CONCLUSION: fQRS was associated with PSM. fQRS may cause PSM in patients with CABG without left bundle branch block due to a conduction defect. PSM and fQRS are predictive of cardiac mortality. Patients diagnosed with PSM and fQRS, should be monitored closely.

RESUMEN

OBJECTIVE: The main causes of spinal cord ischemia are a variety of vascular pathologies causing acute arterial occlusions. We investigated neuroprotective effects of kefir on spinal cord ischemia injury in rats. METHODS: Rats were divided into three groups : 1) sham operated control rats; 2) spinal cord ischemia group fed on a standard diet without kefir pretreatment; and 3) spinal cord ischemia group fed on a standard diet plus kefir. Spinal cord ischemia was performed by the infrarenal aorta cross-clamping model. The spinal cord was removed after the procedure. The biochemical and histopathological changes were observed within the samples. Functional assessment was performed for neurological deficit scores. RESULTS: The kefir group was compared with the ischemia group, a significant decrease in malondialdehyde levels was observed (p<0.05). Catalase and superoxide dismutase levels of the kefir group were significantly higher than ischemia group (p<0.05). In histopathological samples, the kefir group is compared with ischemia group, there was a significant decrease in numbers of dead and degenerated neurons (p<0.05). In immunohistochemical staining, hipoxia-inducible factor-1α and caspase 3 immunopositive neurons were significantly decreased in kefir group compared with ischemia group (p<0.05). The neurological deficit scores of kefir group were significantly higher than ischemia group at 24 h (p<0.05). CONCLUSION: Our study revealed that kefir pretreatment in spinal cord ischemia/reperfusion reduced oxidative stress and neuronal degeneration as a neuroprotective agent. Ultrastructural studies are required in order for kefir to be developed as a promising therapeutic agent to be utilized for human spinal cord ischemia in the future.

RESUMEN

OBJECTIVE: In the post-sternotomy mediastinitis patients, Staphylococcus aureus is the pathogenic microorganism encountered most often. In our study, we aimed to determine the efficacy of antibiotic treatment with vancomycin and tigecycline, alone or in combination with hyperbaric oxygen treatment, on bacterial elimination in experimental S. aureus mediastinitis. METHODS: Forty-nine adult female Wistar rats were used. They were randomly divided into seven groups, as follows: non-contaminated, contaminated control, vancomycin, tigecycline, hyperbaric oxygen, hyperbaric oxygen + vancomycin and hyperbaric oxygen + tigecycline. The vancomycin rat group received 10 mg/kg/day of vancomycin twice a day through intramuscular injection. The tigecycline group rats received 7 mg/kg/day of tigecycline twice a day through intraperitoneal injection. The hyperbaric oxygen group underwent 90 min sessions of 100% oxygen at 2.5 atm pressure. Treatment continued for 7 days. Twelve hours after the end of treatment, tissue samples were obtained from the upper part of the sternum for bacterial count assessment. RESULTS: When the quantitative bacterial counts of the untreated contaminated group were compared with those of the treated groups, a significant decrease was observed. However, comparing the antibiotic groups with the same antibiotic combined with hyperbaric oxygen, there was a significant reduction in microorganisms identified (P<0.05). Comparing hyperbaric oxygen used alone with the vancomycin and tigecycline groups, it was seen that the effect was not significant (P<0.05). CONCLUSION: We believe that the combination of hyperbaric oxygen with antibiotics had a significant effect on mediastinitis resulting from methicillin-resistant Staphylococcus aureus. Methicillin-resistant Staphylococcus aureus mediastinitis can be treated without requiring a multidrug combination, thereby reducing the medication dose and concomitantly decreasing the side effects.

RESUMEN

Venous ulcers that occur due to chronic venous insufficiency are seen on the upper medial malleol of the ankle. Treatment of venous ulcers is protracted and generally the success rate is low. Co-morbid factors play an important role in the success of treatment of venous ulcers. In this case report, we demonstrate successful venous ulcer treatment in a morbidly obese patient with co-morbid conditions.

RESUMEN

PURPOSE: In this study, we aimed to assess the presence and prevalence of paradoxical septal motion (PSM) by myocardial perfusion-gated single-photon emission computed tomography (SPECT) imaging in patients undergoing coronary artery bypass grafting (CABG). METHODS: A total of 172 patients (145 men and 27 women, with a mean age of 64.81 ± 8.93 years) undergoing CABG surgery were included in the study. All selected scintigraphic studies of the patients undergoing CABG were reprocessed. Semiquantitative interpretation of septal perfusion, wall motion, and wall thickening was performed with QPS and QGS programs. Phase analysis parameters were also obtained using the Emory Cardiac Toolbox. According to myocardial perfusion-gated SPECT results, the patients were trichotomized as follows: group 1 (nonischemic PSM): regular perfusion and thickening of the septal wall and abnormal motion of the septal wall; group 2 (ischemic PSM): abnormal perfusion, motion, and thickening of the septal wall; group 3 (non-PSM): normal perfusion, motion, and thickening of the septal wall. The data in each of the three groups were compared using Student's t-test and one-way analysis of variance. RESULTS: No PSM (normal perfusion, motion, and thickening of the septal wall) was observed in 19.2% of patients undergoing CABG, whereas nonischemic PSM (regular perfusion and thickening of the septal wall and abnormal motion of the septal wall) was observed in 60.5% of patients and ischemic PSM (abnormal perfusion, motion and thickening of the septal wall) was seen in 20.3% of patients. CONCLUSION: According to our study results, PSM is fairly common in patients undergoing CABG. It will be beneficial to use myocardial perfusion scintigraphy-gated SPECT, which is a noninvasive examination method, to identify the presence of PSM and investigate whether it is accompanied by ischemia or infarction.

RESUMEN

AIM: Paraplegia due to ischemia-reperfusion (I/R) injury of the spinal cord is a devastating complication of thoracoabdominal aortic surgery. Cysteinyl leukotrienes are potent mediators of inflammation that are associated with I/R injury. The present study was designed to investigate the role of montelukast, a selective reversible CysLT1 receptor antagonist, on spinal cord I/R injury in an experimental model. MATERIAL AND METHODS: Twenty-one male Sprague-Dawley rats were randomly assigned to three groups (n=7 per group) as G1 (no aortic occlusion and montelukast administration), G2 (45 min. aortic occlusion; no montelukast administration) and G3 (45 min. aortic occlusion, 10 mg/kg montelukast administration). After neurologic evaluation using the Motor Deficit Index (MDI) score at the 48th hour of reperfusion, lumbar spinal cords were removed for histopathological evaluation and immunohistochemical staining for HSP70, interleukin-6 and myeloperoxidase (MPO). RESULTS: All rats in the G1 group had a normal neurological status and their MDI score was 0 (p < 0.05). The MDI score of G3 was significantly lower than G2 group (2.8 vs. 5.5; p < 0.05). Vacuolar congestion was found to be significantly lower in G1 than the other groups (p=0.0001). The interleukin-6 receptor level was found to be significantly lower in G3 group than the control group (p=0.013). There was no statistically significant difference found among the groups in terms of the degree of HSP70 and MPO staining. CONCLUSION: Increased generation of leukotrienes in postischemic organs play an important role in I/R injury. The findings of the current study demonstrated that montelukast improved motor recovery and decreased IL-6 levels in spinal cord I/R injury.

RESUMEN

Platelet activation plays a pivotal role in acute coronary syndrome (ACS). We investigated the relationship between platelet distribution width (PDW) and severity of coronary artery disease (CAD) in patients with ACS. A total of 502 patients with ACS were enrolled. High (n = 151) and low PDW (n = 351) groups were defined as patients having values in the third tertile (>17%) and lower 2 tertiles (≤17%). There were significantly higher Gensini score (44 [10-168] vs. 36 [2-132], P < .001), and neutrophil-lymphocyte ratio (3.1 [0.8-12.4] vs. .2.5 [0.3-13], P = .012) and baseline platelet counts were significantly lower (220 [61-623] vs. 233 [79-644] 10(3)/mm3, P = .022) in the high PDW group. The variables PDW >17%, diabetes mellitus, and myocardial infarction were found to be associated with high Gensini score (odds ratio [OR]: 1.91, 95% confidence interval [CI]: 1.27-2.88, P = .002; OR: 2.85, 95% CI: 1.91-4.25, P < .001; OR: 2.67, 95% CI:1.74-4.1, P < .001, respectively). An increased PDW (>17%) is associated with severity of CAD in patients with ACS.

RESUMEN

OBJECTIVE: In this study, we aimed to demonstrate whether the presence of fragmented QRS (fQRS) is associated with the frequency of premature ventricular contractions (PVCs). METHODS: We retrospectively analyzed 282 cases by 24-hour Holter monitorings (HMs) between August 2012 and February 2013. Firstly, the patients were divided into 2 groups with respect to presence of fQRS and then divided into 3 groups with respect to frequency of PVCs as Group 1: seldom PVC (<120 PVCs/day), Group 2: moderate-frequency PVC (120-720 PVCs/day), and Group 3: frequent PVC (>720 PVCs/day). We investigated the predictors of frequent PVCs by using multinomial logistic regression analysis. RESULTS: Ninety-eight patients had fQRS. There was no difference between the 2 groups with respect to body mass index, gender, hypertension, and diabetes mellitus. Patients with fQRS were older (54.9±15.6 vs. 47.0±16.3, p<0.001) and had more family history of coronary artery disease (25% vs. 13%, p=0.012). Patients with fQRS was more likely to be on aspirin therapy (28.6% vs. 10.4%, p<0.001) and have a larger left atrium diameter (33.5±5.7 vs. 30.4±5.8, p=0.001). Presence of fQRS was significantly associated with the frequency of PVCs (for frequent PVC 27.7% vs. 7.6%, p<0.001; for moderate-frequency PVC 18.4% vs. 11.4%, p=0.012); 26.2% of Group 1 (n=202) had fQRS, 46.2% of Group 2 (n=39) had fQRS, and 65.9% of Group 3 (n=41) had fQRS. In the multinomial regression analysis, only age (odds ratio: 4.24, 95% confidence interval 2.08-8.64, p=0.001) and fQRS (odds ratio: 2.11, 95% confidence interval 1.00-4.45, p=0.05) were predictors of frequent PVCs. CONCLUSION: This study demonstrated that the presence of fQRS is associated with frequent PVCs in patients without overt structural heart disease.
