Effect of the number of parity on right heart chamber quantification.

INTRODUCTION: Pregnancy is a process that can cause several physiologic changes to the cardiovascular system such as ventricular hypertrophy and dilation of cardiac chambers. Although there are studies about pregnancy-related changes in echocardiographic examination; there is no data about the long-term effects of parity on these alterations. Therefore, we evaluated the long-term effect of pregnancy on right ventricular (RV) dilation and RV hypertrophy and their relation to the parity number. METHODS: This prospective study included a total of 600 women (200 consecutive women who had no parity, 200 women who had a parity number of 1 to 4 and 200 women who had a parity number of more than 4). Right chambers' measurements were compared between the groups. RESULTS: In echocardiographic analysis, RV and right atrial dimensions and areas and RV wall thickness were higher in parous women. On the other hand, RV systolic function parameters were significantly lower in parous women. These significant changes showed a gradual increase or decrease by increasing parity number. By multivariate hierarchical logistic regression analysis, the four independent factors that increased the risk of RV dilation were age (OR: 1.16 CI: 1.10-1.20), body mass index (OR: 1.05, CI: 1.02-1.08), smoking (OR: 1.87, CI: 1.28-4.02), and giving a birth (OR: 3.94 CI: 1.82-8.81). There was also independent relationship between the number of parity and RV hypertrophy even after adjustment for several confounders. CONCLUSION: Pregnancy-related physiological changes mostly resolve after delivery. This study about long-term effects of pregnancy on RV has demonstrated that there is a significant relation between the number of parity and either RV dilation or RV hypertrophy. Each parity had also additive effect on these changes.

Atrial fibrillation as a preoperative risk factor predicts long-term mortality in elderly patients without heart failure and undergoing hip fracture surgery.

OBJECTIVE: Patients with atrial fibrillation (AF) constitute a significant portion of hip fracture patients, and both diseases tend to present more frequently in older age. Our goal was to evaluate the long-term mortality of patients with AF who were free from heart failure undergoing hip fracture surgery. METHODS: This observational, retrospective study was done in a single research and training hospital setting. Hospital electronic health record data, National Health Registry data, and National Death Registry System data for 233 consecutive patients who were above 65 years of age and were planned to undergo surgery for hip fracture were retrieved and analyzed. An experienced cardiologist evaluated the patients prior to surgery. Each member of the research cohort was categorized into one of the two groups based on their survival status (survivor and non-survivor groups). RESULTS: Of the 233 cases, 89 (38.2%) who were included in the investigation died during the follow-up period. The median long-term follow-up period was 34 (12-42) months. The frequency of AF was significantly higher in the non-survivor group. In multivariable Cox regression analysis, AF (HR: 2.195, 95%CI 1.365-3.415, p<0.001), advanced age, and blood urea level were determined as independent predictors for all-cause long-term mortality. CONCLUSIONS: AF is an independent predictor for long-term death in hip fracture cases above 65 years of age who were free from heart failure.

Preoperative cardiac risk factors associated with in-hospital mortality in elderly patients without heart failure undergoing hip fracture surgery: a single-centre study.

INTRODUCTION: In the present study, our aim was to ascertain the preoperative cardiac risk factors related to the in-hospital mortality in the elderly patients (aged over 65 years) who required preoperative cardiology consultation for hip fracture surgery. MATERIAL AND METHODS: The present study was a retrospective, single-centre study, which enrolled consecutive elderly patients without heart failure scheduled for hip fracture surgery in our institution. In all patients, an anesthesiologist performed a detailed preoperative evaluation and decided the need for the cardiac consultation. Patients underwent preoperative cardiac evaluation by a trained cardiologist using the algorithms proposed in the recent preoperative guidelines. The in-hospital mortality was the main outcome of the study. RESULTS: In total, 277 elderly patients undergoing hip fracture surgery were enrolled in this analysis. The overall in-hospital mortality rate was 12.1% (n=30 cases). In a multivariate analysis, we found that insulin dependency, cancer, urea, presence of atrial fibrillation (AF) (OR: 3.906; 95% CI 1.470 to 10.381; p=0.006) and pulmonary artery systolic pressure (PASP) (OR: 1.057; 95% CI 1.016 to 1.100; p=0.006) were the predictors of in-hospital mortality. The receiver operating characteristic curve analysis revealed that the optimal value of PASP in predicting the in-hospital mortality was 35 mm Hg (area under the curve=0.71; 95% CI 0.60 to 0.81, p<0.001) with sensitivity of 87.7% and specificity of 59.5%. CONCLUSION: The present research found that the preoperative cardiac risk factors, namely AF and PASP, might be associated with increased in-hospital mortality in elderly patients without heart failure undergoing hip fracture surgery.

Predictors of left atrial thrombus in acute ischemic stroke patients without atrial fibrillation: A single-center cross-sectional study

SUMMARY INTRODUCTION: The present study aimed to determine independent predictors of left atrial thrombus (LAT) in acute ischemic stroke (AIS) patients without atrial fibrillation (AF) using transesophageal echocardiography (TEE). METHODS: In this single-center, retrospective study, we enrolled 149 consecutive AIS patients. All of the patients underwent a TEE examination to detect LAT within 10 days following admission. Multivariate logistic regression analysis was performed to assess independent predictors of LAT. RESULTS: Among all cases, 14 patients (9.3%) had a diagnosis of LAT based on the TEE examination. In a multivariate analysis, elevated mean platelet volume (MPV), low left-ventricle ejection fraction (EF), creatinine, and reduced left-atrium appendix (LAA) peak emptying velocity were independent predictors of LAT. The area under the receiver operating characteristic curve analysis for MPV was 0.70 (95%CI: 0.57-0.83; p = 0.011). With the optimal cut-off value of 9.45, MPV had a sensitivity of 71.4% and a specificity of 63% to predict LAT. CONCLUSION: AIS patients with low ventricle EF and elevated MPV should undergo further TEE examination to verify the possibility of a cardio-embolic source. In addition, this research may provide novel information with respect to the applicability of MPV to predict LAT in such patients without AF.

RESUMO INTRODUÇÃO: O presente estudo teve como objetivo determinar indicadores independentes do trombo auricular esquerdo (LAT) em doentes com acidente vascular cerebral isquêmico agudo (AIS) sem fibrilação auricular (AF) utilizando ecocardiografia transesofágica (TEE). MÉTODOS: Neste único centro, estudo retrospectivo, inscrevemos 149 pacientes consecutivos com AIS. Todos os pacientes foram submetidos a exame de TEE para detectar LAT no prazo de dez dias após a admissão. A análise de regressão logística multivariada foi realizada para avaliar preditores independentes do final. RESULTADO: Entre todos os casos, 14 pacientes (9,3%) tiveram um diagnóstico de exame tardio no TEE. Numa análise multivariada, volume médio de plaquetas (VMP) elevado, fração de ejeção do ventrículo esquerdo baixo (EF), creatinina e uma velocidade de pico de esvaziamento do átrio esquerdo reduzida (LAA) foram indicadores independentes da LAT. A área sob a análise da curva característica de operação do receptor para VMP foi de 0,70 (95% IC: 0, 57-0, 83; p=0,011). Com o valor-limite ideal de 9,45, o VMP teve uma sensibilidade de 71,4% e uma especificidade de 63% para prever mais tarde. CONCLUSÃO: Os doentes AIS com EF ventricular baixa e VMP elevado devem ser submetidos a um exame de TEE adicional para determinar a possibilidade de origem cardioembólica. Além disso, esta investigação pode fornecer novas informações sobre a aplicabilidade do VMP para prever tardiamente os doentes sem AF.

Is there a relationship between blood lipids and lumbar disc herniation in young Turkish adults?

INTRODUCTION: Atherosclerosis might diminish the nutrient supply to intervertebral discs (IVD), leading to disc herniation. Therefore, there is interest in determining the possible association between the blood lipid profile and lumbar disc herniation (LDH). We aimed to evaluate the association between blood lipids and LDH in a homogeneous group of patients, controlling for age- and sex-specific effects. MATERIAL AND METHODS: This is a case-control study which consisted of 100 individuals (mean age: 41.25 ±9.09; 50 men and 50 women), classified into two groups, as follows. Group I (G-I) consisted of 50 patients who underwent surgery for symptomatic LDH, while group II (G-II) consisted of 50 patients with nonspecific complaints of a headache, but with no previous history of back and/or leg pain, recruited among patients admitted to the outpatient clinic at the time of the study, and whose age and sex were matched to the study group. Total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), fasting blood glucose, and hemoglobin A1c levels were measured. The TC/HDL-C ratio was calculated. Blood pressure, waist circumference, body mass index, and the history of smoking were included in the analysis. RESULTS: The mean values of the TC, TG, LDL-C, HDL-C levels and TC/HDL-C ratio were 198.38, 132.76, 131.9, 40.38 mg/dl and 5.09, respectively. No statistically significant relationship between the blood lipid profile and LDH was identified in this population. CONCLUSIONS: Blood lipid levels in this young adult Turkish population did not predict LDH, and may not be a leading cause of IVD ischemia and IVD degeneration.

The relationship between epicardial fat tissue thickness and visceral adipose tissue in lean patients with polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is related to metabolic syndrome, insulin resistance, and cardiovascular metabolic syndromes. This is particularly true for individuals with central and abdominal obesity because visceral abdominal adipose tissue (VAAT) and epicardial adipose tissue (EAT) produce a large number of proinflammatory and proatherogenic cytokines. The present study aimed to determine whether there are changes in VAAT and EAT levels which were considered as indirect predictors for subclinical atherosclerosis in lean patients with PCOS. METHODS: The clinical and demographic characteristics of 35 patients with PCOS and 38 healthy control subjects were recorded for the present study. Additionally, the serum levels of various biochemical parameters were measured and EAT levels were assessed using 2D-transthoracic echocardiography. RESULTS: There were no significant differences in mean age (p = 0.056) or mean body mass index (BMI) (p = 0.446) between the patient and control groups. However, the body fat percentage, waist-to-hip ratio, amount of abdominal subcutaneous adipose tissue, and VAAT thickness were higher in the PCOS patient group than in the control group. The amounts of EAT in the patient and control groups were similar (p = 0.384). EAT was correlated with BMI, fat mass, waist circumference, and hip circumference but not with any biochemical metabolic parameters including the homeostasis model assessment of insulin resistance index or the levels of triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein (HDL) cholesterol. However, there was a small positive correlation between the amounts of VAAT and EAT. VAAT was directly correlated with body fat parameters such as BMI, fat mass, and abdominal subcutaneous adipose thickness and inversely correlated with the HDL cholesterol level. CONCLUSIONS: The present study found that increased abdominal adipose tissue in patients with PCOS was associated with atherosclerosis. Additionally, EAT may aid in the determination of the risk of atherosclerosis in patients with PCOS because it is easily measured.

Tricuspid valve thrombus causing acute pulmonary embolism.

The development of thrombus on the tricuspid valve is very rare in adulthood and it needs special attention in clinical practice as it can be confused with vegetation or a tumour. Embolisation due to thrombus may have an acute and unexpected course with a detrimental prognosis and a high death rate during the first 24 h after diagnosis. In this report, we presented a case of mobile tricuspid valve thrombus detected by transthoracic echocardiography that led to recurrent pulmonary embolism.

Missed diagnosis of unruptured, huge left ventricular pseudoaneurysm.
