The relationship of prognostic nutritional index with prognosis and inflammation in patient with heart failure and reduced ejection fraction.

Background: Malnutrition is closely associated with heart failure, and known to be closely associated with mortality and morbidity in these patients. Aims: We investigated the relationship of the prognostic nutritional index (PNI), which is a criterion of nutritional status in patients with heart failure with reduced ejection fraction (HFrEF), with prognosis and parameters indicating inflammation. Methods: 139 patients admitted to the coronary intensive care unit with symptoms of decompensated congestive heart failure were included to the study. Patients were with heart failure with ejection fraction <%40 and decompensated for any reason. Patients who died within 1 year in hospital or follow-up were considered to have reached the endpoint. Groups were divided into 2 groups as Group 1, the exitus; (23 patients, 7 M, mean age; 69.2 ± 15.0 years) and group 2, the non-exitus; (116 patients, 57 M, mean age; 69.3 ± 11.5 years). PNI was calculated with the formula ALB(g/L) + 5 × Total lymphocyte count(109/L). Results: PNI was significantly lower in group 1. Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and systemic inflamatory index values were significantly higher in group 1. PNI was significantly associated with these parameters. Conclusion: Low PNI scores in HFrEF patients may be associated with a worse prognosis and hematological parameters indicating more negative inflammation. PNI was found to be an independent predictor of mortality.

The Impact of Septoplasty on Cardiopulmonary Functions in Patients With Nasal Septal Deviation: A Prospective Comprehensive Analysis of Echocardiographic Outcome and Serum N-Terminal Pro BNP Levels.

ABSTRACT: This study was designed to evaluate the impact of septoplasty on cardiopulmonary functions in patients with nasal septal deviation (NSD). A total of 30 consecutive adult patients (mean [standard deviation] age: 33.7 [10.9] years, 56.7% were males) who underwent septoplasty due NSD were included. Visual analog scale scores, nose obstruction symptom evaluation scale scores, serum N-terminal Pro BNP levels, and cardiologic examination findings on electrocardiogram, transthoracic echocardiography, and exercise treadmill testing were evaluated both 7 days before and 3-months after septoplasty operation. A significant decrease was noted in mean (standard deviation) visual analog scale scores (8.27 [0.83] versus 1.87 [0.73], P < 0.001), and nose obstruction symptom evaluation scores (83.7 [4.9] versus 12.7 [(5.4], P < 0.001) from preoperative to postoperative period, while maximum effort capacity was improved significantly (11.8 [1.9] versus 13.1 [2.1], P = 0.010) after septoplasty. Echocardiography findings at 3rd postoperative month revealed significant decrease in pulmonary artery systolic pressure (22.2 [3.2] versus 19.0 [3.6], P = 0.001), whereas significant increase in trans-mitral early diastolic rapid filling (E wave, 0.82 [0.14] versus 0.87 [0.13], P = 0.011), peak systolic velocity (S, 0.11 [0.02] versus 0.12 [0.02], P = 0.002), tricuspid annular plane systolic excursion (22.6 [3.2] versus 24.9 [2.9], P = 0.002), and right ventricle stroke volume (0.14 [(0.02] versus 0.15 [0.02], P = 0.013). In conclusion, our findings indicate favorable outcome of septoplasty in NSD patients not only in terms of improved nasal airflow but also cardiopulmonary functions, particularly the exercise capacity, pulmonary artery pressure, and right ventricular systolic functions. In this regard, our findings emphasize the important role of treating NSD patients without delay, given the likelihood of septoplasty to reverse the changes in the pulmonary artery system and to prevent onset of permanent cardiopulmonary dysfunction via amelioration of chronic obstruction of the upper respiratory tract.

Prognostic significance of malnutrition scores in elderly patients for the prediction of contrast-induced acute kidney injury.

BACKGROUND: Malnutrition reflects the general condition of a patient including physical condition, protein turnover, and immune competence. Contrast-induced acute kidney injury (CI-AKI) is a disorder that adversely affects the prognosis of older adults. In our study, we aimed to show the relationship between CI-AKI and malnutrition status in elderly patients over 65 years of age with chronic coronary artery disease (CAD). METHODS: Study enrolled 360 consecutive patients with coronary angiography performed because of chronic coronary artery disease. Patients pre-procedural and post-procedural blood samples were taken and prognostic nutritional index (PNI), controlling nutritional status (CONUT) score, and geriatric nutritional risk index (GNRI) malnutrition scores were calculated. RESULTS: The median age of the patients included in the study was 69 (67-72, IQR) and CI-AKI was seen in 91 (25.2%) patients. Univariate regression analysis showed that age, diabetes mellitus, baseline creatinine, body weight-adapted contrast agent, haemoglobin, left ventricular ejection fraction, CONUT score, PNI score, and GNRI score were independent predictors of CI-AKI. In model 1, increase in CONUT score (2 to 5) (OR: 3.21 (2.11-4.88), in model 2, increase in PNI score (37.4 to 45) (OR: 0.34, (0.24-0.49)), and in model 3, increase in GNRI score (89.5 to 103.8) (OR: 0.55, (0.38-0.81)) were independently associated with the presence of CI-AKI. PNI showed better results than other models in discriminating the predictable capability for CI-AKI. CONCLUSION: Malnutrition assessment of elderly patients before performing diagnostic or interventional coronary procedures could help clinicians to identify patients with elevated risk for CI-AKI.

Assessment of pulmonary arterial stiffness in patients with cirrhosis: A prospective cohort study.

INTRODUCTION: In the current literature, several studies show that PAS (pulmonary artery stiffness) is associated with RV (right ventricular) dysfunction, PAH (pulmonary arterial hypertension), and disease severity in subjects with structural cardiac disease, HIV (human immunodeficiency virus), and chronic lung disease. Hence, our main aim was to use PAS to show the early changes in the pulmonary vascular region in subjects with cirrhosis. MATERIAL AND METHODS: In this prospective cross-sectional study, 39 subjects who were being followed up with cirrhosis and 41 age- and sex-matched healthy subjects were included in this study. For each case, the PAS value was obtained by dividing mean peak velocity of the pulmonary flow by the PfAT (pulmonary flow acceleration time). RESULTS: The measured PAS was 23.62 ± 5.87 (Hz/msn) in cirrhotic participants and 19.09 ± 4.16 (Hz/msn) in healthy cases (P < .001). We found a positive statistical significance between PAS and RVSP (right ventricle systolic pressure)/sPAP (systolic pulmonary arterial pressure) (r = .395; P = .013). PAS was an independent predictor that was associated with cirrhosis disease according to multivariate LR (logistic regression) analysis (OR: 1.209; 95% CI: 1.059-1.381; P = .005). CONCLUSION: Based on the study results, we consider that PAS may help in the early detection of findings in the pulmonary vascular area, even if the RV function findings or sPAP is within the normal range.

Effect of non-dipper pattern on echocardiographic myocardial work parameters in normotensive individuals.

BACKGROUND: It is known that non-dipper pattern (NDP) is associated with adverse outcomes in hypertensive patients. However, there is insufficient data on the outcome of NDP in normotensive individuals. Using myocardial work (MW) analysis, as a new echocardiographic examination method, this study aimed to determine the early myocardial effects of NDP in normotensive individuals. METHODS: This study included 70 normotensive individuals who were followed by ambulatory blood pressure monitoring (ABPM). The subjects were divided into two groups according to dipper pattern (DP) and NDP. Conventional, strain, and MW findings were compared between the groups by making echocardiographic evaluations. RESULTS: The demographic characteristics, laboratory parameters, and measurements of cardiac chambers, and left ventricular (LV) walls were similar between the groups. There was no statistical difference between the groups in terms of LV 3-2-4 chambers strains and global longitudinal strain (GLS) values. LVMW parameters, global work index (GWI), and global constrictive work (GCW) were not statistically different between groups (2012 ± 127, 2069 ± 137, p = 0.16; 2327 ± 173, 2418 ± 296, p = 0.18, respectively). However, global waste work (GWW) and global work efficiency (GWE) parameters were different between the groups (144 ± 63.9, 104 ± 24.8, p < 0.001; 93.2 ± 3.17, 95.4 ± 1.28, p < 0.001, respectively). In regression analysis, GWW was independently associated with NDP. GWW model showed better results with higher likelihood chi-square and R2 values than GLS model in discriminating the predictable capability for NDP status. CONCLUSION: The results of MW analysis in this study showed that GWW values were higher and the GWE values were lower in normotensive individuals with NDP.

Relative Fat Mass Index can be solution for obesity paradox in coronary artery disease severity prediction calculated by SYNTAX Score.

BACKGROUND: The relation between body mass index (BMI) and coronary artery disease (CAD) extension remains controversial. A new score was developed to estimate body fat percentage (BFP) known as Relative Fat Mass (RFM) Index. This study aimed to evaluate the value of RFM Index in predicting the severity of the CAD, compared with other anthropometric measurements. METHODS: A total of 325 patients with chronic CAD were investigated. RFM, BFP, BMI and other anthropometric characteristics of patients were measured before angiography. CAD severity was determined by SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery trial (SYNTAX) Score. The association between SYNTAX Score and variables was evaluated using linear regression models. In order to compare the model performance, R-squared (R2), Akaike's information criterion, Bayesian information criterion and root mean square error were used. RESULTS: Univariate linear regression outcome variable, SYNTAX was used to determine whether there was any relationship between variables. Independent variables were included in the multivariable linear logistic regression models. The analysis showed that in model 1, RFM (ß coefficient: 2.31 (0.90 to 3.71), p=0.001)), diabetes mellitus (ß coefficient: 3.72 (1.67 to 3.76), p=0.004)), haemoglobin (ß coefficient: -2.12 (-3.70 to -0.53), p=0.03) and age (ß coefficient: 1.83 (0.29 to 3.37), p=0.02)) were statistically significant. The adjusted R2 values in model 1 were higher than model 2 (BFP) and model 3 (BMI) (0.155, 0.137 and 0.130, respectively), and χ2 values of RFM were higher than BFP and BMI (10.5, 3.4 and 1.0, respectively). CONCLUSION: RFM Index is a more reliable and compatible marker of obesity in showing the severity of CAD compared to BMI.

The relationship of body composition indices with the significance, extension and severity of coronary artery disease.

BACKGROUND AND AIMS: It is still unclear which anthropometric parameter is most associated with significant coronary artery disease (CAD). We examined the relationship of the prevalence and severity of coronary artery disease with body composition indices. METHODS AND RESULTS: Patients aged 18-80 years who were admitted to the cardiology outpatient clinic with any complaints, and were indicated for coronary angiography as a result of the examinations, were included in this study and divided into two groups. Group 1 had significant stenosis (161 patients, 104 males, mean age: 64.1 ± 10.5 years), while Group 2 had non-significant stenosis (75 patients, 48 males, mean age: 58.9 ± 11.8 years). Significant stenosis was defined as narrowing of 50% or more of the arterial lumens in any vessel or its lateral branch. Height, weight, waist and hip circumferences and body composition indices of all patients were measured. The SYNTAX and Gensini scores were calculated for all patients undergoing angiography. Group 1 had significantly higher waist circumferences (WC), body roundness indices (BRI), body fat percentages, and waist/height ratios than Group 2. In the correlation analysis, WC, BRI, waist/hip ratio and waist/height ratio were significantly correlated with the Gensini score. WC, hip circumference, BRI, body fat percentage and waist/height ratio were significantly correlated with the SYNTAX score. In the multivariate regression analysis, BRI was the parameter best related to significant CAD. CONCLUSION: BRI, body fat percentage, waist circumference and waist/height ratio were higher in patients with significant stenosis. BRI was the parameter most closely related to the Gensini and SYNTAX scores and to significant CAD.

Novel electrocardiography parameter for paroxysmal atrial fibrillation in acute ischaemic stroke patients: P wave peak time.

INTRODUCTION: In this study, we aimed to investigate the usefulness of P wave peak time (PWPT), a novel ECG parameter, in patients who were diagnosed with acute ischaemic stroke (IS) and had paroxysmal atrial fibrillation (PAF) on Holter monitoring. MATERIALS AND METHODS: In this retrospective cohort study, we included 90 consecutive patients with acute IS who were admitted to our hospital between January 2017 and July 2019. PWPT was described as the time from the beginning of the P wave to its peak, and it was measured from leads DII and VI. The PAF diagnosis was confirmed if it was detected on the ECG during palpitation or in rhythm during the Holter recordings. RESULTS: In this study, 34 (37.7%) patients with acute IS were diagnosed with PAF. In multivariate analyses, the independent predictors of PAF were age, PWPT in lead VI and PWPT in lead DII (OR: 1.34, 95% CI 1.15 to 1.56; p<0.001). A receiver operating curve analysis demonstrated that area under the curve values for PWPT in lead DII for PAF were 0.88 (95% CI 0.81 to 0.95, p<0.001). The cut-off value for PWPT in lead DII in predicting PAF was 68.5 ms with a sensitivity of 82.4% and a specificity of 75.0%. CONCLUSION: To the best of our knowledge, this is the first study to demonstrate a significant relationship between PWPT in lead DII and PAF among patients with acute IS.

The relationship of age-adjusted Charlson comorbidity index and diurnal variation of blood pressure.

BACKGROUNDS: Charlson Comorbidity index (CCI) is a scoring system to predict prognosis and mortality. It exhibits better utility when combined with age, age-adjusted Charlson Comorbidity Index (ACCI). The aim of this study was to evaluate the relationship between ACCI and diurnal variation of blood pressure parameters in hypertensive patients and normotensive patients. METHODS: We enrolled 236 patients. All patients underwent a 24-h ambulatory blood pressure monitoring (ABPM) for evaluation of dipper or non-dipper pattern. We searched the correlation between ACCI and dipper or non-dipper pattern and other ABPM parameters. To further investigate the role of these parameters in predicting survival, a multivariate analysis using the Cox proportional hazard model was performed. RESULTS: 167 patients were in the hypertensive group (87 patients in non-dipper status) and 69 patients were in the normotensive group (41 patients in non-dipper status) of all study patients. We found a significant difference and negative correlation between AACI and 24-h diastolic blood pressure (DBP), awake DBP, awake mean blood pressure (MBP) and 24-h MBP and awake systolic blood pressure(SBP). Night decrease ratio of blood pressure had also a negative correlation with ACCI (p = 0.003, r = -0.233). However, we found a relationship with non-dipper pattern and ACCI in the hypertensive patients (p = 0.050). In multivariate Cox analysis sleep MBP was found related to mortality like ACCI (p = 0.023, HR = 1.086, %95 CI 1.012-1.165) Conclusion: ACCI was statistically significantly higher in non-dipper hypertensive patients than dipper hypertensive patients while ACCI had a negative correlation with blood pressure. Sleep MBP may predict mortality.

Biventricular noncompaction cardiomyopathy with severe systolic and diastolic dysfunction in a systemic sclerosis patient.

Non-compaction cardiomyopathy (NCM) is a rare congenital cardiomyopathy characterized by deep increased trabeculation in one or more segments of the ventricle. The apical segment of the left ventricle is most commonly affected, but left ventricular basal segment, biventricular involvement or right ventricle predominance have also been described. While some neuromuscular anomalies and myopathies had been described in systemic sclerosis patients, coexistence of chronic inflammatory disorders and NCM is unclear. This paper presents a case of biventricular NCM with severe systolic and diastolic dysfunction in a 40-year-old female diffuse cutaneous systemic sclerosis patient.

Right ventricular isovolumic acceleration in acute pulmonary embolism.

OBJECTIVE: In this study, we examined the role of isovolumic acceleration (IVA) measured with right ventricle (RV) tissue Doppler imaging (TDI) to predict the presence of acute pulmonary embolism (APE) in hemodynamically stable patients with clinical suspicion of APE. MATERIALS AND METHOD: This study included 25 hemodynamically stable (systolic blood pressure >90 mmHg) patients diagnosed with APE for the first time. Twenty-five subjects with similar demographic characteristics in whom APE was excluded due to preexisting clinical suspicion were also enrolled as the control group. All control group subjects were enrolled after proved to have no evidence of APE on imaging. Both groups were compared with respect to RV-IVA measured with TDI in addition to conventional echocardiographic parameters. RESULTS: Among the echocardiography parameters, only RV-IVA was impaired in patients with hemodynamically stable APE compared to controls (2.85 [1.37-6.42] m/sec(2) vs. 3.32 [2.24-6.52] m/sec(2) , respectively; P = 0.02). A receiver operating characteristic (ROC) analysis was performed to determine the RV-IVA value to predict clinically suspected APE. A cutoff level of 3.22 m/sec(2) had a sensitivity of 64% and a specificity of 60%; a cutoff level of 3.17 m/sec(2) had a sensitivity of 64% and a specificity of 64%; and a cutoff level of 3.10 m/sec(2) had a sensitivity of 60% and specificity of 64% (ROC area under curve: 0.691, 95% CI: 0.543-0.839, P = 0.02). CONCLUSION: Results of our study suggest that RV-IVA may be a useful parameter to detect subtle alterations in RV and may predict the presence of APE in hemodynamically stable patients.

The relationship of visceral adiposity with endothelial functions and subclinical atherosclerosis in obese individuals.

INTRODUCTION: On the cardiovascular system, obesity accelerates atherosclerosis progression, inducing pathophysiological changes that are detectable already from young adults. Endothelial dysfunction is one of the earliest vascular alterations observed in obesity. In this study, we aimed to determine endothelial functions and carotid intima-media thickness in patients with obesity without overt cardiovascular disease. METHODS: The study was conducted with 112 individuals with obesity without overt cardiovascular disease and any chronical diseases (BMI>30 kg/m2) (84 female, 28 male, mean age: 46.3±11.2 years) and 49 healthy individuals with no diseases (33 female, 16 male, mean age: 44.6±10.2 years). All patients were examined for endothelial functions by the flow-mediated dilatation (FMD) method and carotid intima-media thicknesses (CIMT). All measurements were performed by the same imaging specialist, averaging 3 different measurements. In addition to the body mass index and waist circumference visceral adiposity index (VAI) and triponderal mass index (TPI) also calculated. RESULTS: The percentage of FMD obtained by brachial artery ultrasound was significantly lower, visceral adipose tissue, perirenal adipose tissue thicknesses measured by abdominal ultrasound and CIMT were significantly thicker in Group 1 compared to Group 2. FMD had a negative significant correlation with body mass index, visceral adipose tissue thickness, perirenal adipose tissue thickness, and waist and hip circumferences, and carotid intima-media thickness and CIMT had a significant correlation with visceral adipose tissue thickness, perirenal adipose tissue thickness, VAI, TPI and waist, hip circumferences. CONCLUSION: Individuals with obesity have impaired endothelial functions and greater carotid intima-media thicknesses compared to healthy individuals. This impairment in endothelial functions is proportional to the amount of visceral and perirenal fat accumulation. Parameterss reflecting visceral fat distribution such as VAI and TPI are also related with these impairment.

Usability of myocardial work parameters to demonstrate subclinical myocardial involvement in normotensive individuals with exaggerated hypertensive response in treadmill exercise testing.

Early determination of changes in myocardial functions is essential for the protection of cardiovascular diseases. This study aimed to evaluate myocardial work parameters in healthy individuals who developed an exaggerated hypertensive response during the treadmill exercise test procedure. The study included a total of 64 patients for whom an exercise electrocardiography test was planned for functional capacity evaluation. The study population was divided according to the presence of exaggerated hypertensive response to exercise (EBPRE) (SBP/DBP ≥210/105 mmHg in males ≥190/105 mmHg in females) and normal blood pressure response to exercise (NBPRE). Patients' echocardiographic evaluations were made at rest, and myocardial work parameters were calculated. There was no statistical difference between the groups (NBPRE vs. EBPRE, respectively) in terms of left ventricular 2,3 and 4 chamber strains and global longitudinal strain (GLS) values (-20.6 ± -2.3, -19.7 ± -1.9, p:.13; -21.3 ± -2.7, -21 ± -2.4, p:.68; -21.2 ± -2.2, -21.2 ± -2.3, p:.93; and -20.8 ± -1.5, -20.4 ± -1.5, p:.23, respectively). Global constrictive work (GCW), global waste work (GWW), and global work efficiency (GWE) were not statistically different between the two groups (2374 ± 210, 2465 ± 204, p:.10; 142 ± 64, 127 ± 42, p:.31; 94.3 ± 2.5, 95.1 ± 1.5, p:.18, respectively). In contrast, global work index (GWI) parameters were different between the two groups (2036 ± 149, 2147 ± 150, p < .001). The GWI was independently associated with EBPRE (odds ratio with 95% 3.32 (1.02-11.24), p = .03). The partial effect plots were used for GWI to predict EBPRE, according to the results, an increase in GWI predicts probability of exaggerated hypertensive response. In conclusion, Myocardial work analyses might be used to identify early signs of myocardial involvement in normotensive patients with EBPRE.

A case of spontaneous multivessel coronary artery dissection presenting with acute myocardial infarction and ventricular tachycardia.

Spontaneous coronary artery dissection (SCAD) is a rare cause of myocardial ischemia. Multivessel SCAD is much rarer than single vessel involvement and acute coronary syndrome remains the most common clinical presentation of a patient with SCAD. It predominantly occurs in association with atherosclerosis or in the absence of atherosclerosis. We, hereby, present a case of spontaneous multivessel coronary artery dissection in a 35-year-old male patient presenting with chest pain and ventricular tachycardia following emotional stress and discuss the etiology and treatment options.

Can aortic elastic parameters be used for the diagnosis of volume overload in patients with end stage renal disease.

BACKGROUND: We aimed here to investigate hydration status by echocardiography in end stage renal disease (ESRD) patients. METHODS: 25 ESRD patients [15 males; mean age: 54.0±16.6 years; 13 hemodialysis; 12 peritoneal dialysis] were considered eligible for this study. We also examined 29 healthy volunteers as a control group (17 males; mean age: 46.5±12.8 years). Body composition analysis using the bioimpedance spectroscopy technique was performed for volume overload diagnosis. The ratio of extracellular water (ECW) to height was used as volume indices. The aortic elastic parameters were calculated by echocardiography. A correlation analyses was performed between the ratio of ECW to height indicating the volume overload and the aortic elastic parameters e.g. Aortic strain (AS), Aortic distensibility (AD) and Aortic stiffness index (ASI). RESULTS: The ratio of ECW to height that indicates volume overload in ESRD patients was considerably higher than that in the control group (10.25±1.98 L/m vs. 8.66±1.22 L/m, p=0.001). There was a negative correlation between the ratio of ECW to height and AS and AD and a positive correlation between the ratio of ECW to height and ASI. CONCLUSION: Given the importance of the diagnosis and follow up of volume overload, the results show that aortic elasticity measurements, being easy to perform and replicate, can be used for this purpose.

The value of P wave dispersion in predicting reperfusion and infarct related artery patency in acute anterior myocardial infarction.

PURPOSE: The aim of this study is to investigate whether P wave dispersion (PWD), measured before, during and after fibrinolytic therapy (FT,) is able to predict successful reperfusion and infarct related artery (IRA) patency in patients with acute anterior MI who received FT. METHODS: Sixty-eight patients who presented with acute anterior MI were enrolled in the study. An electrocardiogram was performed before and at 30, 60, 90 and 120 minutes after the start of FT. PWD was defined as the difference between maximum and minimum P wave duration on standard 12-lead surface electrocardiogram. A multivariate logistic regression model was used to assess whether PWD was predictor of IRA patency and ST-segment resolution (STR) on electrocardiogram. RESULTS: PWD120 was significantly lower in patients with STR on electrocardiogram (38 patients) compared with those without STR (30 patients) (44.8±11.5 vs. 52.9±10.3 ms; p < 0.001). PWD120 was found to be significantly lower in patients with patent IRA (31 patients) compared to those with occluded IRA (37 patients) (42.3±9.7 vs. 53.5±10.6 ms; p < 0.001). Logistic regression analysis revealed that PWD120 significantly predicted STR and IRA patency. A ≥51.6 ms PWD120 can predict an occluded IRA with a 87% sensitivity, ≥51 ms PWD120 can predict no reperfusion with a 74% sensitivity. CONCLUSION: PWD values, which were higher than 51 ms and 51.6 ms in patients who received fibrinolytic therapy, can serve as a marker of failed reperfusion and occluded IRA. PWD values, in combination with other reperfusion parameters, can contribute to the identification of rescue PCI candidates.

An asymptomatic needle in the left ventricular anterolateral wall: a prison inmate's strange radio antenna.

A foreign body such as a needle in the heart can be life-threatening. While this may occur accidentally, needles may be inserted into the body by psychiatric patients or in cases involving domestic violence. A needle can migrate through the thorax toward the heart. In drug users, needles may also reach the right ventricle via the peripheral veins. Cardiac injury can occur via the esophagus after swallowing a needle. The clinical outcome may vary from an asymptomatic situation to tamponade or shock, depending on how severely the cardiac structures are affected. In injuries involving the thorax, pneumothorax may cause sudden shortness of breath. Here, we report the case of a 34-year-old male prison inmate who accidentally lodged a pin in his left ventricle while asleep. As he has refused surgery, it was decided to follow the patient carefully.

The Relationship of Comorbidities with Intensive Care Unit Admission and Mortality in Patients with COVID-19.

OBJECTIVE: Comorbid conditions are known to be associated with poor prognosis in coronavirus disease 2019. This study aimed to investigate the effects of comorbidity burdens of inpatients, identified by the Charlson Comorbidity Index, on their mortalities. METHODS: A total of 150 patients who presented to the emergency department of our hospital with various complaints and symptoms were diagnosed with coronavirus disease 2019 as a result of the testing and received inpatient treatment (87 males, mean age 61.6 ± 13.8 years) were included in the study. Charlson Comorbidity Index scores were calculated. Patients were classified into 2 groups based on the state of exitus: group 1, those who did not survive; 33 patients, 19 males; 68.3 ± 11.8 years and group 2, those who survived; 117 patients, 68 males; 59.7 ± 13.8 years. RESULTS: In all patients, the exitus rate was 22%, the rate of intensive care follow-up was 46%, and the intubation rate was 37.3%. The Charlson Comorbidity Index scores were significantly higher in group 1 compared to group 2. Multivariate logistic regression analyses demonstrated that the Charlson Comorbidity Index score was an independent predictor of in-hospital mortality (odds ratio: 1.990, 95% CI: 1.314-3.015, P = .001). The cut-off value for the Charlson Comorbidity Index to predict in-hospital mortality was 5.5, with 81.8% sensitivity and 73.5% specificity. CONCLUSIONS: The Charlson Comorbidity Index score, which can be obtained at the time of admission, could be associated with the prognosis of coronavirus disease 2019 patients. Those with a Charlson Comorbidity Index score greater than 5.5 could be more associated with negative outcomes and mortality.

The influence of circadian variations on echocardiographic parameters in healthy people.

BACKGROUND: Our aim was to investigate whether diastolic functions, myocardial velocities and pulmonary vein flow show diurnal variation within a 24-hour day. METHOD AND RESULTS: Fourty-four healthy subjects with no history of cardiovascular or systemic diseases (32 males, 12 females; mean age 34.7 ± 8.7 years, mean BMI: 25.5 ± 3.5 kg/m(2)) were enrolled in this study. None of the subjects had a history, symptoms or signs of cardiovascular or systemic diseases or were taking drugs of any kind. All underwent echocardiographic examination at 7 a.m., 1 p.m., 7 p.m., and 1 a.m. M-mode systolic, diastolic velocities and pulmonary vein flow measurements were obtained. There were no differences in systolic and diastolic blood pressures and heart rate. The left atrial diameter was greater at 1 p.m. (3.80 ± 0.44; P = 0.031). The isovolumic contraction time (ICT) was found to be the shortest (41 ± 12 msn; P = 0.050), and ejection time (ET) the longest (290 ± 31 msn; P = 0.017) at the 1 am measurements. The mitral myocardial performance index (MPI) was lowest during the 1 a.m. measurements (0.42 ± 0.11; P = 0.001). The systolic myocardial velocities (Sm) obtained from the septum and inferior region were significantly higher at 1 p.m. and lower at 7 a.m. (9.17 ± 1.79, 10.25 ± 2.29; 8.11 ± 1.06, 8.63 ± 1.49; P < 0.05). The late diastolic velocities obtained from the lateral, inferior and anterior regions were higher at 1 p.m. and 7 p.m. CONCLUSION: The left ventricular diameter and ejection fraction did not exhibit circadian variations. However, our data indicate that some parameters reflecting diastolic function, systolic myocardial velocities and MPI, as well as left atrial diameter change at different times of the day, independent of blood pressure and heart rate.

Influence of menstrual cycle on p wave dispersion.

Female gender is an independent risk factor for some types of arrhythmias. We sought to determine whether the menstrual cycle affects P wave dispersion, which is a predictor of atrial fibrillation. The study population consisted of 59 women in follicular phase (mean age, 29.3 ± 7.7 years) (group F) and 53 women in luteal phase (mean age, 28.1 ± 6.8 years) (group L). The ECGs of 35 patients (mean age, 26.4 ± 4.5) were obtained in both follicular and luteal phase. Both groups underwent a standard 12-lead surface electrocardiogram recorded at 50 mm/s. Maximal (Pmax) and minimal P wave durations (Pmin) were measured. P wave dispersion (PD) was defined as the difference between Pmax and Pmin. PD was significantly higher in group L than group F (46.6 ± 18.5 versus 40.1 ± 12.7; P < 0.05). Pmin was significantly lower in group L than group F (51.6 ± 12.1 versus 59.1 ± 12.1; P = 0.002). When we compared ECGs in different phases of the 35 patients, PD was significantly higher in luteal phase than follicular phase (53.2 ± 12.3 versus 42.8 ± 10.2; P < 0.05). Pmin was significantly lower in luteal phase than follicular phase (47.6 ± 6.6 versus 56 ± 10.1; P = 0.05). We detected a significant correlation between the day of the menses and PD (r = 0.27; P < 0.05). PD was increased in luteal phase compared to follicular phase, and this difference was more prominent as the days of the cycle progressed.
