Investigating the impact of couple counseling based on the CHARMS model on sexual quality of life and marital satisfaction of wives of men suffering from myocardial infarction: a study protocol.

INTRODUCTION: Cardiovascular diseases are a common chronic illness in adults, with implications for health and psychological well-being. These implications not only affect the patients themselves but also impact family members, especially the spouses of patients. One significant issue and consequence of this disease is its impact on marital relationships and sexual satisfaction, which can also influence other dimensions of quality of life. The aim of the current study is to determine the effect of couple counseling based on the CHARMS model on sexual quality of life and marital satisfaction of wives of men suffering from myocardial infarction. METHOD: This study is a clinical randomized controlled trial. Sampling will be done on a convenience basis. Participants will be randomly allocated into two groups: control (50 couples) and intervention (50 couples). Couples in 6 groups of 8 members each will attend counseling sessions based con the CHARMS model, with sessions held weekly and lasting for 60 min. Data collection tools will include Demographic information questionnaire, Women's Sexual Quality of Life Questionnaire, Enrich Marital Satisfaction Questionnaire, Sexual Compatibility Questionnaire and Perceived Quality of Relationship Dimensions Questionnaire, which will be completed by women in both groups before and after the intervention. Data will be analyzed using appropriate statistical tests and SPSS software. DISCUSSION: This trial will evaluate whether a counseling intervention based on the CHARMS model can enhance sexual quality of life and marital satisfaction of wives of men with myocardial infarction in Urmia city. TRIAL REGISTRATION: IRCT code: IRCT20240218061046N1.

Cardiovascular diseases are a common chronic illness in adults, with implications for health and psychological well-being. One significant issue and consequence of this disease is its impact on marital relationships and sexual satisfaction, which can also influence other dimensions of quality of life.This trial will evaluate whether a counseling intervention based on the CHARMS model can enhance sexual quality of life and marital satisfaction of wives of men with myocardial infarction in Urmia city. A CHARMS-based intervention with 4 principles addresses the sexual and marital relationship empowerment of couples following a severe heart attack. These principles include: (1) Counseling and providing information on the impact of cardiovascular diseases on sexual desires. (2) Counseling and providing information on a healthy sexual life and communication skills strategies with the sexual partner. (3) Counseling on uncovering false beliefs and misconceptions regarding relationship risks and fears. (4) Providing tips and solutions for resuming sexual relations after a severe heart event, addressing sexual and interpersonal challenges. This intervention sets patients' expectations of sexual relationships based on a final focus on "sexual intimacy" as the ultimate goal of therapy.This study is a clinical randomized controlled trial. Participants will be randomly allocated into two groups: control (50 couples) and intervention (50 couples). Couples in 6 groups of 8 members each will attend counseling sessions based con the CHARMS model, with sessions held weekly and lasting for 60 min.

Interrelation among exercise training, cardiac hypertrophy, and tissue kallikrein-kinin system in athlete and non-athlete women.

Introduction: The tissue kallikrein-kinin system is an endogenous homeostatic pathway, which its stimulation is associated with cardioprotection. The present study aimed to determine the effect of exercise training on plasma tissue kallikrein (TK) and bradykinin (BK) and their association with cardiac hypertrophy. Methods: 22 non-athlete and 22 athlete women were exposed to acute (Bruce test) and chronic (12-week swimming training) exercises. 2D echocardiography was used to evaluate morphological and functional features of the heart. Plasma concentrations of TK and BK were quantified by ELISA. Results: Athletes had significantly higher values of left ventricle end-diastolic diameter index (LVEDDI) and left ventricle mass index (LVMI) than non-athletes. Exercise intervention affected echocardiographic features in neither of the study groups. Chronic exercise training notably increased plasma levels of TK and BK, which increase was more pronounced in the athletes. Plasma TK negatively correlated with LVEDDI (r=-0.64, P=0.036 and r=-0.58, P=0.027) and LVMI (r=-0.51, P=0.032 and r=-0.63, P=0.028) in the non-athlete and athlete groups. In opposition, there was a positive correlation between plasma TK and left ventricle ejection fraction in non-athletes (r=0.39, P=0.049) and athletes (r=0.53, P=0.019). Conclusion: The upregulation of the tissue kallikrein-kinin system may be a protective mechanism against excessive cardiac hypertrophy induced by chronic exercise training.

Echocardiographic Parameters Associated with Bendopnea in Patients with Systolic Heart Failure.

Background: Bendopnea, defined as dyspnea while bending, can be observed in patients with heart failure (HF). In this study, we investigated the frequency of this symptom in patients with systolic HF and its association with echocardiographic parameters. Methods: In this study, patients with left ventricular ejection fraction (LVEF) ≤45% and decompensated HF referred to our clinics were prospectively recruited. All the patients were examined by cardiologists for collecting data on the presence of bendopnea and baseline characteristics. They also underwent electrocardiographic and echocardiographic examinations. All findings were compared between the patients with or without bendopnea. Results: A total of 120 patients at a mean age of 65.19±12.62 years were evaluated, and 74.8% were men. Bendopnea was observed in 44.2% of the patients. The etiology of HF was ischemic in most patients (81.9%), and the functional class of most patients (85.9%) was III or IV. The mortality rate at the 6-month follow-up was comparable between the patients with or without bendopnea (6.1% vs 9.5%; P=0.507). The waist circumference (odds ratio [OR], 1.037, 95% confidence interval [CI], 1.005 to 1.070; P=0.023), paroxysmal nocturnal dyspnea (OR, 0.338, 95% CI, 0.132 to 0.866; P=0.024), and right atrial size (OR, 1.084, 95% CI, 1.002 to 1.172; P=0.044) were associated with bendopnea. Conclusion: Bendopnea can be frequently found among patients with systolic HF. This phenomenon is associated with obesity and baseline symptoms of patients and right atrial size upon echocardiographic examinations. It can help clinicians with the risk stratification of HF patients.

Echocardiographic and laboratory findings in coronary slow flow phenomenon: cross-sectional study and review.

BACKGROUND: Coronary sow-flow phenomenon (CSFP) is defined as slow passage of the contrast injected into the coronary arteries without distal obstruction of the vessel. METHODS: The present study was a cross-sectional, descriptive-analytical study performed at the Seyed-al-Shohada Heart Center during 2018-2019. The eligible patients based on the inclusion and exclusion criteria were divided into the study group showing the CSFP and the control group with normal epicardial coronary arteries. RESULTS: The study included 124 patients. 67.9% of the study group and 39.4% of the control group were male patients (p-value = 0.001), and the mean patient age was 52.18 ± 12.55 and 51.77 ± 10.36 years in the study and control groups, respectively (p-value = 0.18). The study group had a significantly higher BMI than the control group (p < 0.05) and also a higher prevalence of smoking and hypertension. The variables of ALC, Hct, Plt, MPV, RDW, Cr, triglyceride, TC, and LDL, were higher in the study group. Given the echocardiographic findings, the mean E wave was significantly lower in the study group, while the control group had a significantly higher GLS (p-value = 0.01). Also, left anterior descending artery was the most common artery involved with CSFP. CONCLUSION: The CSFP was significantly more common in men, smokers, hypertensive patients, and patients with high BMI. Moreover, these patients had significantly higher platelet count, MPV, LDL, and FBS. Some other laboratory variables were also higher in these patients. Given the echocardiographic findings, mild diastolic dysfunction and low GLS were also observed in the study group.

Ventricular Dysfunction in Patients with Coronary Slow-Flow Phenomenon: A Single-center Case-control Study.

BACKGROUND: Coronary slow-flow phenomenon (CSFP), characterized by delayed distal vessel opacification of contrast, in the absence of significant epicardial coronary stenosis, has effects on exercise capacity and clinical outcomes. The aim of this study was to explore the systolic and diastolic function of patients with CSFP and to compare it with a group of controls with normal coronary anatomy and flow. MATERIALS AND METHODS: In this case-control study, 45 consecutive CSFP patients and 45 age-, body mass index-, and presentation season-matched controls with normal coronary arteries and normal coronary flows were enrolled from Seyyedoshohada Heart Center from March 2015 to March 2016. A transthoracic echocardiography was done by a blinded echocardiographer using both conventional and tissue Doppler imaging techniques. RESULTS: Patients with CSFP were more likely to be male (P = 0.006) and smoker (P = 0.02) compared to controls. Other risk factors were not different between the two groups. There were no differences between groups in terms of the peak early (E) and late (A) diastolic velocities, deceleration time, early (E') and late (A') peak diastolic velocities at the mitral annulus, and the systolic mitral annular velocity (S'). Global longitudinal strain and peak systolic strain rates was lower in patients with CSFP compared to controls (-16.7% ±2.4% vs. -18.9% ±1.6%, P < 0.001 and 1.10 ± 0.1 vs. 1.24 ± 0.3, P = 0.008, respectively). CONCLUSION: Patients with CSFP showed signs of the left ventricular systolic dysfunction in tissue Doppler echocardiography, which underlines the importance of close follow-up in these patients. Patients with CSFP should be screened for ventricular function preferably by tissue Doppler echocardiography.

Predictors of coronavirus disease 19 (COVID-19) pneumonitis outcome based on computed tomography (CT) imaging obtained prior to hospitalization: a retrospective study.

PURPOSE: Computed tomography (CT) has been utilized as a diagnostic modality in the coronavirus disease 19 (COVID-19), while some studies have also suggested a prognostic role for it. This study aimed to assess the diagnostic and prognostic value of computed tomography (CT) imaging in COVID-19 patients. METHODS: This was a retrospective study of fifty patients with COVID-19 pneumonia. Twenty-seven patients survived, while 23 passed away. CT imaging was performed in all of the patients on the day of admission. Imaging findings were interpreted based on current guidelines by two expert radiologists. Imaging findings were compared between surviving and deceased patients. Lung scores were assigned to patients based on CT chest findings. Then, the receiver operating characteristic curve was used to determine cutoff values for lung scores. RESULTS: The common radiologic findings were ground-glass opacities (82%) and airspace consolidation (42%), respectively. Air bronchogram was more commonly seen in deceased patients (p = 0.04). Bilateral and multilobar involvement was more frequently found in deceased patients (p = 0.049 and 0.014, respectively). The mean number of involved lobes was 3.46 ± 1.80 lobes in surviving patients and 4.57 ± 0.60 lobes in the deceased patients (p = 0.009). The difference was statistically significant. The area under the curve for a lung score cutoff of 12 was 0.790. CONCLUSION: Air bronchogram and bilateral and multilobar involvement were more frequently seen in deceased patients and may suggest a poor outcome for COVID-19 pneumonia.

Association of epicardial fat thickness assessed by echocardiography with the severity of coronary artery disease.

Introduction: Epicardial fat thickness (EFT) can reflect risk of cardiovascular disease particularly coronary artery disease (CAD). The aim of this study was to investigate the association of EFT assessed by echocardiography and presence as well as severity of CAD. Methods: Two hundred and twenty consecutive patients who candidate for coronary angiography because of possible CAD were studied. EFT was evaluated in standard parasternal long axis (PlAX) and parasternal short axis (PSAX) view from 3 cardiac cycles at the end of systole and diastole. The severity of CAD was defined in two ways: (1) SYNTAX score, (2) number of vessels with significant lesion. Results: PLAX (EFTS) (EFT in systole) and PLAX (EFTd) (EFT in diastole) were significantly higher in patients with CAD in comparison with patients without CAD (P = 0.046, P = 0.041 respectively). There was a significant correlation between PLAX (EFTS) (P = 0.05), PLAX (EFTd) (P = 0.04) and SYNTAX score. There was no statistically significant relationship between EFT and number of diseased vessel (P > 0.05). Multivariate analysis was done for adjusting the effects of confounding factors and it showed that EFT (OR: 10.53, P = 0.004) was significantly correlated severe CAD as assessed by the SYNTAX score. Conclusion: EFT assessed by transthoracic echocardiography was higher significantly in patients with CAD than in normal patients. EFT as an easily available and cost-effective echocardiographic feature might be useful to predict complexity of CAD.

Association of Toxoplasma gondii infection with cardiovascular diseases: a cross-sectional study among patients with heart failure diseases in Urmia, North-West of Iran.

Toxoplasmosis is a disease caused by the protozoan parasite Toxoplasma gondii. Infection with T. gondii is one of the most common parasitic diseases in humans and other warm-blooded animals with global distribution and generally, one-third of human populations are estimated to be contaminated with this parasite. The prevalence of infection varies according to age, geographical location and dietary habits. The socioeconomic losses caused by the disease can be costly for the community. Acquired toxoplasmosis is potentially associated with schizophrenia, Alzheimer's disease, driving accidents, self-injury and suicide. Also, unusual strains of parasite that are genetically different from the rest (atypical strains) are responsible for several cases of lethal acquired parasites in people with safe immunity, which highlights the potential danger of this parasite in public health. As there is no comprehensive study on the association between toxoplasmosis and cardiovascular diseases in Iran, therefore, current study aimed at assessing the relationship between cardiovascular disease and toxoplasmosis among cardiac patients at the Seyyed al-Shohada specialist Cardiology Centre, Urmia, Iran. This study investigated the seropositivity rate for anti-Toxoplasma IgG antibodies by ELISA in patients with cardiovascular diseases. So, 375 patients with cardiovascular diseases and 336 healthy volunteers were selected for this investigation. The seropositivity rate of anti-Toxoplasma IgG antibodies was significantly higher in cardiovascular patients (63.73%) than in healthy volunteers (37.64%) (P<0.001). Also, a positive association was observed between anti-T. gondii IgG antibody seropositivity and cat contact (P≤0.001, OR: 5.178; 95% CI: 1.97-13.57), consumption of raw or undercooked meat (P≤0.001, OR: 0.3; 95% CI: 0.15-0.61), and consumption of not boiled milk (P≤0.001, OR: 0.26, 95% CI: 0.12-0.54). Our results indicate that T. gondii infection is associated with heart disease and suggest that heart disease might be related with a chronic infection. Risk factors associated with T. gondii exposure found in the present study may help design future prevention strategies against T. gondii infection.

Clinical and radiological characteristics of pediatric patients with COVID-19: focus on imaging findings.

PURPOSE: CT imaging has been a detrimental tool in the diagnosis of COVID-19, but it has not been studied thoroughly in pediatric patients and its role in diagnosing COVID-19. METHODS: 27 pediatric patients with COVID-19 pneumonia were included. CT examination and molecular assay tests were performed from all participants. A standard checklist was utilized to extract information, and two radiologists separately reviewed the CT images. RESULTS: The mean age of patients was 4.7 ± 4.16 (mean ± SD) years. Seventeen patients were female, and ten were male. The most common imaging finding was ground-glass opacities followed by consolidations. Seven patients had a single area of involvement, five patients had multiple areas of involvement, and four patients had diffuse involvement. The sensitivity of CT imaging in diagnosing infections was 66.67%. Also, some uncommon imaging findings were seen, such as a tree-in-bud and lung collapse. CONCLUSION: CT imaging shows less involvement in pediatric compared to adult patients, due to pediatric patients having a milder form of the disease. CT imaging also has a lower sensitivity in detecting abnormal lungs compared to adult patients. The most common imaging findings are ground-glass opacities and consolidations, but other non-common imaging findings also exist.

Association of circular Klotho and insulin-like growth factor 1 with cardiac hypertrophy indexes in athlete and non-athlete women following acute and chronic exercise.

Owing to the role of insulin-like growth factor 1 (IGF-I) in cardiac hypertrophy and the ability of Klotho in inhibiting the IGF-I action, we investigated effects of exercise on plasma Klotho and IGF-I and their association with cardiac hypertrophy. In this study, 10 non-athlete and 10 athlete women underwent a Bruce test (acute exercise) and 12-weeks water aerobics training (chronic exercise). Electrocardiographic parameters, plasma IGF-I and Klotho levels were measured in different time courses. The exercise training could significantly increase left ventricular end-diastolic diameter index (LVEDDI) in the non-athletes. Plasma levels of IGF-I significantly increased following acute and chronic exercises. The Klotho levels at the baseline were higher in athletes than non-athletes and its levels significantly increased immediately after acute exercise in both groups. The Klotho levels significantly decreased in non-athletes 24 h after chronic exercise, but its level was still higher than the baseline in the athletes. We found positive and negative correlations between cardiac hypertrophy indexes (LVEDDI and left ventricular mass index) with respectively IGF-I and Klotho. In conclusion, we found a stimulatory effect of acute and chronic exercises on plasma IGF-I and Klotho and association of IGF-I with exercise-induced cardiac hypertrophy. Moreover, Klotho could act as a negative regulator for exercise-induced cardiac hypertrophy.

The association of serum vitamin D concentration and ventricular dysfunction among patients with acute coronary syndrome.

OBJECTIVE: To determine if vitamin D deficiency was associated with higher odds of left ventricular dysfunction among patients with acute coronary syndrome (ACS) and, if so, to determine whether this association was mediated by increased inflammation as measured by C-reactive protein (CRP) and white blood cell count (WBC). METHODS: This was a cross-sectional study of 170 participants with ACS. Multiple logistic regression was used to examine the association between the outcome of ventricular performance and serum vitamin D concentrations. We also determined whether CRP and WBC meet standard criteria as the mediators between left ventricular ejection fraction and vitamin D deficiency. RESULTS: Participants with vitamin D deficiency were more likely to have ventricular dysfunction (OR: 2.12, 95% CI: 1.2-5.23). WBC counts did not meet one of the criteria for mediation. However, the WBC was an effect modifier such that the association of vitamin D deficiency and ventricular dysfunction was only present among participants with WBC more than 11,000. CONCLUSION: This study found that vitamin D deficiency was associated with higher odds of ventricular dysfunction. Further longitudinal and experimental studies are necessary to confirm this finding and to determine if there is a role for vitamin D supplementation therapy in preventing ventricular dysfunction in select patient populations.

Short-Term High-Dose Vitamin E to Prevent Contrast Medium-Induced Acute Kidney Injury in Patients With Chronic Kidney Disease Undergoing Elective Coronary Angiography: A Randomized Placebo-Controlled Trial.

BACKGROUND: Contrast medium-induced acute kidney injury (CIAKI) is a leading cause of acquired renal impairment. The effects of antioxidants have been conflicting regarding the prevention of CIAKI. We performed a study of vitamin E use to decrease CIAKI in patients undergoing elective coronary angiography. METHODS AND RESULTS: In a placebo-controlled randomized trial at 2 centers in Iran, 300 patients with chronic kidney disease-defined as estimated glomerular filtration rate <60 mL/min per 1.73 m(2)-were randomized 1:1 to receive 0.9% saline infusion 12 hours prior to and after intervention combined with 600 mg vitamin E 12 hours before plus 400 mg vitamin E 2 hours before coronary angiography or to receive placebo. The primary end point was the development of CIAKI, defined as an increase ≥0.5 mg/dL or ≥25% in serum creatinine that peaked within 72 hours. Based on an intention-to-treat analysis, CIAKI developed in 10 (6.7%) and 21 (14.1%) patients in the vitamin E and placebo groups, respectively (P=0.037). Change in white blood cell count from baseline to peak value was greater in the vitamin E group compared with the placebo group (-500 [-1500 to 200] versus 100 [-900 to 600]×10(3)/mL, P=0.001). In multivariate analysis, vitamin E (odds ratio 0.408, 95% CI 0.170-0.982, P=0.045) and baseline Mehran score (odds ratio 1.257, 95% CI 1.007-1.569; P=0.043) predicted CIAKI. CONCLUSIONS: Prophylactic short-term high-dose vitamin E combined with 0.9% saline infusion is superior to placebo for prevention of CIAKI in patients undergoing elective coronary angiography.

Prognostic value of mean platelet volume in patients undergoing elective percutaneous coronary intervention.

OBJECTIVE: We sought to determine the role of mean platelet volume (MPV) for predicting long-term outcomes of elective percutaneous coronary intervention (PCI). METHODS: On the basis of retrospective cohort study, we collected characteristics of 680 patients undergoing elective PCI from October 2005 to August 2010. The patients who had preoperative MPV were assessed for developing major adverse cardiac events (MACE) during 1-year follow-up. They were categorized into two groups including MPV <9.6 fL (n=89) and MPV ≥9.6 fL (n=92). Data were analyzed using t-test, chi-square test, Pearson correlation, receiver operating characteristic (ROC) curve and logistic regression. RESULTS: One-hundred eighty one patients (26.6%) met inclusion criteria. The MACE was observed in 29 patients (16%); and its rate in low- and high-MPV groups was 11.2% and 20.7%, respectively (p=0.084). MPV was significantly higher in the patients with left ventricular ejection fraction (LVEF) <40% compared with that of ≥40% (p<0.001). There were a significant and negative correlation between MPV and platelet count (r=-0.305, p<0.001), and significant and positive correlations between MPV and platelet distribution width (PDW) and platelet large cell ratio (P-LCR) (r=0.615, p<0.001 and r=0.913, p<0.001; respectively). The best MPV cut-off point was 9.25 fL; the sensitivity and specificity were 79% and 38%, respectively. Elevated MPV was the best predictor of MACE at 1-year follow-up (OR=11.359, 95% CI 2.481-51.994, p=0.002). CONCLUSION: The results indicate that preoperative MPV is an independent predictor of the MACE at 1-year follow-up in the patients undergoing elective PCI. Moreover, it may be useful for risk stratification in such cases.

Slow coronary flow phenomenon and increased platelet volume indices.

BACKGROUND AND OBJECTIVES: We sought to determine the relationship between mean platelet volume (MPV), platelet distribution width (PDW), and platelet larger cell ratio (P-LCR) with slow coronary flow (SCF). SUBJECTS AND METHODS: Eighty participants who underwent coronary angiography were divided into two groups, 50 participants with SCF as case group, and 30 with normal coronary flow (NCF) as control group. Baseline characteristics and laboratory data were collected before angiography. RESULTS: Platelet volume indices MPV (10.8±1.2 fL), PDW (14.5±2.2 fL), and P-LCR (30.5±8.1%) in the SCF group were significantly (p<0.05) higher than those (10.1±0.9 fL, 13.2±1.8 fL, and 26.8±6.8%, respectively) in the NCF group. The patients with three SCF arteries had significantly higher platelet volume indices compared to those with NCF arteries; however, the patients with one SCF artery did not. Based on linear regression model, MPV, PDW, and P-LCR were independent predictors of mean infarction frame counting (TFC). In multivariate analysis, MPV {odds ratio (OR)=32.393, 95% confidence interval (CI)=1.189-882.606, p=0.039} and P-LCR (OR=0.566, 95% CI=0.330-0.937, p=0.028) were independent predictors of SCF. CONCLUSION: Platelet volume indices MPV, PDW, and P-LCR were associated with both the presence and extent of SCF.

Acute pulmonary embolism caused by enlarged uterine leiomyoma: a rare presentation.

PATIENT: Female, 42. FINAL DIAGNOSIS: Acute pulmonary embolism. SYMPTOMS: Chest pain • dyspnea. MEDICATION: Streptokinase • Warfarin. CLINICAL PROCEDURE: .- SPECIALTY: Cardiology and Neoplasm. OBJECTIVE: Management of emergency care. BACKGROUND: Deep venous thrombosis (DVT) and subsequent pulmonary embolism (PE) caused by pelvic vein compression are rare and life-threatening complications of leiomyoma of the uterus. CASE REPORT: We report a 42-year-old virgin woman with a history of leiomyoma who presented to the emergency department with complaints of dyspnea and pleuritic chest pain with transient spotting. On physical examination, she had a non-tender abdomen with a 20-week size uterus. Imaging investigations revealed an acute DVT in her left leg and a huge uterine-derived mass compressing the common iliac veins. Transesophageal echocardiography (TEE) demonstrated an echogenic mass in her right pulmonary artery consistent with thrombosis. The patient was completely cured using thrombolytic therapy and myomectomy, and was well at 1 year after thrombolysis. CONCLUSIONS: PE caused by pelvic vein compression is a rare complication of leiomyoma, which should be considered. Thrombolytic therapy associated with myomectomy can be implemented for treating such cases, and TEE can be used for diagnosing suspected high-risk PE.

The relationship between vitamin D status and idiopathic lower-extremity deep vein thrombosis.

BACKGROUND: Vitamin D has been shown to have an anticoagulant effect. A decrease in 25-hydroxyvitamin D [25(OH)D] concentration has also been associated with an increased risk of venous thromboembolism. Hence, we sought to determine the relationship between 25(OH) D levels and idiopathic lower-extremity deep vein thrombosis (DVT). METHODS: In a case control study, a total of 82 participants with idiopathic lower-extremity DVT were enrolled along with 85 sex- and age-matched healthy participants as controls. The plasma 25(OH)D levels were measured in all the studied samples. RESULTS: The participants' mean age was 47.1±12.3 years. Baseline characteristics were not significantly different between the groups. The concentration of 25(OH)D was significantly lower in the DVT group compared to that of the control group (17.9±10.3 versus 23.1±12.5 ng/mL, P=0.004). The prevalence of participants with deficient 25(OH)D levels was significantly higher in the both DVT and control groups than those with sufficient 25(OH)D levels (68.3% versus 13.4%, and 49.4% versus 28.2%, respectively, P=0.027). In a multivariate analysis, 25(OH)D levels and sex were found to be the only independent predictors of DVT (odds ratio [OR] 1.05, 95% confidence interval [CI] 1.02-1.08, P=0.001 and OR 0.51, 95% CI 0.26-1.00, P=0.049, respectively). CONCLUSION: Low levels of 25(OH)D are associated with idiopathic lower-extremity DVT. Further investigation is needed to establish determinants and probable causative role of 25(OH)D.

Concurrent mobile and in situ types of right heart thrombi.

Right-sided heart thrombus is a life-threatening condition that necessitates immediate therapy. Detection of right-sided heart thrombus is usually via transthoracic echocardiography. Generally, thrombolysis is considered a treatment of choice, but there is currently no consensus about the optimal therapeutic choice. We present a case of multiple right atrial thrombi with concurrent mobile and broad-based in situ thrombi in a patient with a history of chronic obstructive pulmonary disease, which was completely resolved by thrombolysis following a failed Heparin infusion. The patient was sent home in good clinical condition and was stable at 3 months' follow-up.

Cardioprotective effect of vitamin E: rescues of diabetes-induced cardiac malfunction, oxidative stress, and apoptosis in rat.

AIM: This study was designed to assess the effect of vitamin E on cardiac autonomic neuropathy, cardiomyocyte apoptosis, and the status of oxidative stress in the heart under hyperglycemic conditions, in vivo. METHODS: Wistar male rats (n=16) were made hyperglycemic by streptozotocin at 6 months of age. Normal Wistar rats (n=8) of the same age were used as the control group. Diabetic rats were divided into two groups, nontreated and those treated with vitamin E (300 mg/day). Stable hyperglycemic status was proved by levels of blood sugar and HbA(1c). Lipid peroxidation, protein oxidation, and cellular antioxidant defense were measured by 8-isoprotane, protein carbonyl content, and superoxide dismutase (SOD) activity, respectively. RESULTS: Cardiac complications such as autonomic neuropathy as prolonged QT interval along with significant increases in level of 8-isoprotane, protein carbonyl content, and SOD activity were observed after 6 weeks. Structural abnormality was also observed as severe induction of apoptosis in cardiomyocytes. CONCLUSION: Significant decline in apoptosis, lipid peroxidation, protein oxidation, and QT interval resulted from vitamin E administration, which strongly implies that this radical scavenger may promote a convalescing effect on diabetic cardiomyopathy through the attenuation of oxidative stress and abrogation of apoptotic signals, which was verified by restoring normal QT interval.
