The importance of pulmonary pulse transit time in indicating right ventricular dysfunction and pulmonary arterial stiffness in rheumatoid arthritis.

SUBJECT: Rheumatoid arthritis patients are at risk of developing cardiovascular disease such as right heart failure and pulmonary hypertension (PH). Arterial stiffness can be used to assess pulmonary hemodynamics. Noninvasive approaches can also be used to assess pulmonary hemodynamics. Recently, there have been reports that pulmonary pulse transit time (PPTT) may also be a useful measure. This study aims to examine the effects of pulmonary hemodynamic alterations on PPTT in RA patients. METHODS: Forty RA patients and 40 healthy controls were included in the study. Sociodemographic characteristics, laboratory data, and echocardiographic examinations were performed in both groups. Conventional echocardiographic examination included left and right ventricular systolic and diastolic diameters, right ventricular myocardial performance index (RVMPI), right ventricular diastolic function, estimated pulmonary artery systolic pressure (sPAP), tricuspid annular plane systolic excursion (TAPSE), pulmonary artery stiffness (PAS), and PPTT. Right ventricular diastolic and systolic volumes, right ventricular ejection fraction (RVEF), and right ventricular fractional area change (RVFAC) were determined by four-dimensional echocardiography (4DE). RESULTS: There was no difference between the sPAP values of the patients. RVMPI and PAS were increased in RA patients compared with controls. The PPTT was shortened in RA patients and correlated with RVEF, RVFAC, RVMPI, TAPSE/sPAP, disease duration, and C-reactive protein (CRP). In univariate linear regression analysis, PPTT (p < .001) was thought to be an independent predictor of PAS. RVFAC, disease duration, and PAS were also independent predictors of PPTT. CONCLUSION: In RA patients, PPTT may be the first evidence of early abnormalities in pulmonary vascular hemodynamics. PPTT and PAS are the values that may predict each other in RA patients. Due to its more practical application, PPTT can be used instead of PAS to assess pulmonary hemodynamics.

Association between pan-immune-inflammation value and no-reflow in patients with ST elevation myocardial infarction undergoing percutaneous coronary intervention.

Noreflow is a condition associated with a poor prognosis in ST segment elevation myocardial infarction patients. It has been shown that many inflammatory markers and index such as procalcitonin, C-reactive protein, neutrophil to lymphocyte ratio, systemic immune inflammatory index (SII), are associated with noreflow. We used a brand-new index pan-immune-inflammation value (PIV) to retrospectively evaluate the relationship between PIV and noreflow. A total of 1212 patients were included for analysis. Noreflow was observed in 145 patients. In multivariate analysis, PIV (odds ratio (OR): 1.025; [1.002-1.115], p < 0.001), baseline ejection fraction (OR: 0.963; [0.934-0.993], p = 0.015), stent length (OR: 1.032; [1.010-1.054], p = 0.004), age (OR: 1.034; [1.014-1.053], p = 0.001) and pain to PCI time (OR: 1.003 [1.002-1.005], p < 0.001) were observed to be the independent predictors of noreflow. ROC curve analysis showed that the best cut off value of PIV for predicting noreflow was ≥889 with 77.2% sensitivity and 77.5% specificity (AUC, 0.828; 95% CI [0.806-0.849]). A ROC curve comparison analysis was performed to compare PIV and SII. The predictive power of PIV was higher than SII (differences between areas: 0.154; p < 0.001). According to our findings, an increase in PIV is an independent predictor of noreflow in patients with STEMI.

Evaluation of pulmonary artery stiffness and right ventricle functions in polycythemia vera patients by transthoracic echocardiography.

INTRODUCTION: Polycythemia vera (PV) is known to be a subgroup of chronic myeloproliferative neoplasms and is recognized as a cause of pulmonary hypertension (PH). Pulmonary artery stiffness (PAS) is a relatively new noninvasive echocardiographic index developed to evaluate the structural features and functions of the pulmonary vascular bed. In this study, we aimed to evaluate right ventricular (RV) functions and PAS in PV patients and healthy controls. METHODS: A group of 65 consecutive PV patients and 40 healthy controls were included in the study. RV global longitudinal strain (RVGLS) and RV free wall longitudinal strain were (RVFwLS) evaluated using two-dimensional (2D) strain echocardiography. RV volume, systolic and diastolic functions were evaluated with three-dimensional (3D) echocardiography. PAS was calculated using the maximum frequency shift (MFS) and acceleration time of the pulmonary artery flow trace. RESULTS: PAS values were significantly higher in the PV group than in the control group (25.2 ± 5.2 vs. 18.2 ± 4.2, p < .001). We found that tricuspid annular plane systolic excursion (TAPSE) (p < .001), RV fractional area change (p < .001) and RV ejection fraction (p < .001) measurements evaluated by 3D echocardiography were significantly lower in the PV group. CONCLUSION: In our study, PAS values were higher in PV patients than in the healthy control group. Patients with PV may have subclinical RV dysfunction, and PAS value can be used in the early diagnosis of PH and RV dysfunction in this patient group.

Systemic Immune-Inflammation Index as a Predictor of Microvascular Dysfunction in Patients With Cardiac Syndrome X.

The systemic immune inflammation index (SII; platelet count x neutrophil-lymphocyte ratio), a new marker, predicts adverse clinical outcomes in many conditions, including acute and chronic coronary syndromes, pulmonary embolism, cancers, and contrast nephropathy. The aim of this study was to determine the relationship between SII and microvascular dysfunction in patients with Cardiac Syndrome X (CSX); 105 patients with CSX and 105 patients with normal coronary arteries were included. Microvascular dysfunction was determined angiographically using myocardial blush grade (MBG) and total myocardial blush score (TMBS). We observed that the SII levels were higher in the CSX (+) group (687 [355-2211] vs 418 [198-1614], P<.001). The SII levels were also found to be significant independent predictors for CSX in multiple regression analysis (P=.001). SII levels >440 had 83.8% sensitivity and 55.2% specificity (area under the curve [AUC]: .923, 95% CI: .895-.999, P<.001) for predicting CSX. There is a significant correlation between SII levels and CSX.

The relationship between bioelectrical impedance parameters and pulmonary artery stiffness in obese subjects.

OBJECTIVES: Obesity is a public health problem that needs to be treated and it occurs as a result of excessive fat accumulation in the body. The relationship between obesity and pulmonary hypertension is well known. The aim of this study is to evaluate the relationship between pulmonary artery stiffness, right ventricular functions and bioelectrical impedance parameters in obese, overweight, and healthy individuals. METHODS: In this study, 41 obese (17 female and 24 male, mean age 43.5±10.3), 39 overweight (20 female and 19 male, mean age 38.6±10.4), 34 healthy control group (19 female and 15 male, mean age 40.5±8.6) were included. Anthropometric measurements and bioelectrical impedance parameters of all participants were performed. Right ventricular functions and pulmonary artery stiffness were evaluated by using conventional echocardiography. RESULTS: Right ventricle myocardial performance index, pulmonary artery stiffness values were statistically different between groups. Positive correlation was observed between pulmonary artery stiffness and Body Mass Index, Waist and Hip circumferences. Significant negative correlation was observed between muscle to fat ratio and pulmonary artery stiffness. In the linear regression analysis, it was observed that the muscle to fat ratio was independent predictor of pulmonary artery stiffness (ß = -1.835; 95%CI(-2.434 - - .784); p < 0.001). CONCLUSIONS: This study showed that right ventricular function was impaired and pulmonary artery stiffness increased in obese individuals. These findings could be considered as early markers of pulmonary hypertension in obese patients who do not yet have clinical evidence of cardiovascular disease.

The CHA2DS2-VASc risk score predicts successful endovascular treatment in patients with acute ischemic stroke.

OBJECTIVES: Acute ischemic stroke is a common cause of mortality and morbidity worldwide. Percutaneous endovascular intervention is an important treatment method in ischemic stroke. Endovascular procedure success is associated with the clinical outcome of the patients. The CHA2DS2-VASC score is an important score used to determine the risk of ischemic stroke in patients with atrial fibrillation. In our study, we aimed to evaluate the relationship between procedure success and CHA2DS2-VASC score in patients with acute ischemic stroke who underwent endovascular intervention. MATERIALS AND METHODS: A total of 102 consecutive patients who underwent endovascular intervention with acute ischemic stroke were included in the study. The admission CHA2DS2-VASc scores of the patients were recorded. After the procedure, the relationship between the TICI score and the CHA2DS2-VASc score was evaluated. RESULTS: CHA2DS2-VASc score was significantly higher in the group that resulted in unsuccessful endovascular intervention (2.78 ± 1.44, 5.02 ± 1.77 p < .001). Receiver-operating characteristics analysis revealed the cutoff value of CHA2DS2-VASc score ≥3 as a predictor of unsuccessful intervention with 76,6% sensitivity and 83,3% specificity, positive predictive value 50%, negative predictive value 84,6% (area under the curve [AUC]: 0.827,95% CI: 0.739-0.895, p < .001). In the multivariate analysis; atrial fibrillation ([ß] = 4.201; [CI]: 1.251-14.103, p = .020), CHA2DS2-VASc score ([ß] = 0.053; [CI]: 0.004-0.750, p = .030) were found independent predictors for unsuccessful intervention treatment. CONCLUSIONS: In our study, we showed that the CHA2DS2-VASc score is associated with the success of endovascular intervention in patients with acute ischemic stroke who underwent percutaneous endovascular treatment.

The CHA2DS2-VASc Risk Score Predicts Total Occlusion in Infarct-Related Arteries in Patients With Non-ST Elevation Myocardial Infarction.

Early detection of total coronary artery occlusion (TO) in non-ST elevation myocardial infarction (NSTEMI) patients may be beneficial since invasive treatments are initiated more rapidly in appropriate patients. Previous studies have shown that the CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, previous stroke, vascular disease, age between 65 and 74 years, female gender) score is associated with thrombus burden in acute coronary syndromes. We investigated the association between the CHA2DS2-VASc risk score and TO in patients with NSTEMI who underwent coronary angiography. TIMI (thrombolysis in myocardial infarction) flow 0 was defined as TO and TIMI flow 1-3 was defined as non-total occlusion (non-TO). The NSTEMI patients (n = 400) included were separated into two groups: those with (n = 138) and without (n = 262) TO. We observed that the CHA2DS2-VASc score was higher in the TO group (3.86 ± 2.32 vs 2.15 ± 1.79, P <.001). The Global Registry of Acute Coronary Events (GRACE) score (P = .002) and the CHA2DS2-VASc score (P < .001) were also found to be significant independent predictors for total occlusion in multiple regression analysis. A CHA2DS2-VASc score ≥3 had 68.1% sensitivity and 64.0% specificity (area under the curve (AUC): 0.657, 95% CI: 0.585-0.725, P < .001) for predicting TO. The CHA2DS2-VASc score was an effective tool that predicted TO in patients with NSTEMI.

Fragmented QRS complexes are associated with subclinical left ventricular dysfunction in patients with Behcet's disease: Four-dimensional speckle tracking echocardiography.

BACKGROUND: Behcet's disease (BD) is a chronic systemic inflammatory disease in which early detection of cardiac involvement is essential. The aim of this study was to assess the left ventricular (LV) functions in BD patients using four-dimensional (4D) speckle tracking echocardiography (STE) and to test the correlation between LV dysfunction and the presence of QRS fragmentation. METHODS: This cross-sectional study included 64 Behcet's patients and 48 healthy volunteers. The BD group was divided into two subgroups depending on the presence (fQRS+) or absence (fQRS-) of fragmented QRS (fQRS). In both groups, left ventricular global area strain (LV-GAS), global radial strain (GRS), global longitudinal strain (GLS), and global circumferential strain (GCS) were obtained with 4D echocardiography. RESULTS: GAS, GRS, GLS, and GCS values were significantly different in Behcet's patients and in healthy volunteers. GLS and GAS values were lower in the fQRS+ than in the fQRS- group (-15.8 ± 1.8 and -17.9 ± 1.6, P = .001 vs -25.0 ± 3.1 and -29.2 ± 4.2, P < .001, respectively). The duration of disease was longer in fQRS+ than in fQRS- patients (120.8 ± 67.4 vs 71.0 ± 40.5, P < .001). Multiple linear regression analysis showed that fQRS and disease duration were independent predictors of LV-GAS. CONCLUSIONS: Four-dimensional STE may be helpful for the prediction of early cardiac dysfunction in patients with BD. The presence of fQRS may be an indicator of subclinical LV dysfunction.

Subclinical left ventricular dysfunction in Sjögren's syndrome assessed by four-dimensional speckle tracking echocardiography.

OBJECTIVE: The aim of this study was to evaluate the left ventricular (LV) systolic strain by four-dimensional speckle tracking echocardiography (4D-STE) in order to provide the early detection of myocardial dysfunction in patients with Sjögren's syndrome (SS). METHODS: Forty consecutive patients with primary SS diagnosed at the rheumatology outpatient clinic and 35 age- and sex-matched healthy volunteers were included in the study. 4DSTE was performed, and global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), and global area strain (GAS) were measured. 4DSTE results were compared with the healthy volunteers. RESULTS: No significant differences were observed between the GRS and GCS values of the two groups. A significant difference was observed in the GLS and GAS measurements between the two groups (P = .005 for GLS, P < .001 for GAS). Positive correlation was detected between disease duration and LV-GLS and LV-GAS. CONCLUSION: We demonstrated subclinical systolic dysfunction in SS patients by 4DSTE, which is a sensitive marker of ventricular dysfunction. Deterioration of the LV became more evident as duration of the disease increased. Therefore, we believe that a cardiac evaluation will be of benefit to patients with long-term SS.

Assessment of left atrial volume and function in patients with Sjögren's syndrome using three-dimensional echocardiography.

OBJECTIVE: We used real time, three-dimensional transthoracic echocardiography (3DTTE) to evaluate left atrial (LA) volume and mechanical function in patients with primary Sjögren's syndrome (SS). METHODS: We prospectively included 42 consecutive patients with primary SS and 42 controls who were similar in terms of basal characteristics. 3DTTE was used to assess LA function. RESULTS: Maximum LA volume, minimum LA volume, pre-atrial contraction LA volume, LA Active Stroke Volume (ASV), LA Total Stroke Volume (TSV), maximal left atrial volume index (LAVImax), Left atrial pre-contraction volume index, and Left atrial minimum volume index, ASV index, and TSV index were significantly higher in the SS group, and the LA Total Emptying Fraction, LA Expansion Index, and LA Passive Emptying Fraction were significantly lower. Although the active emptying fraction was higher in the SS group, the difference was not statistically significant. LAVImax was positive correlated with disease duration (r = .753). CONCLUSION: Left atrial function is impaired in SS patients and serves as an early marker of subclinical cardiac involvement.

Association between fragmented QRS and left ventricular dysfunction in acromegaly patients.

Background: In acromegaly patients; it has been observed that heart failure may develop even in the absence of predisposing factors such as hypertension, diabetes mellitus, so a specific acromegalic cardiomyopathy has been suggested. We aimed to evaluate the fQRS frequency in acromegaly patients and the left ventricular (LV) functions of acromegaly patients with fQRS.Methods: Our study included 60 acromegalic patients. Each patient underwent conventional echocardiography and tissue Doppler imaging. The patients included were separated into two groups: those with (n:23) and without (n:37) fQRS.Results: Significant differences were identified between fQRS(+) and fQRS (-) groups with respect to disease duration (p < .001), Left ventricular end diastolic volume (EDV) (p < .001), E velocity (p < .001), E\A ratio (p < .001), E' velocity (p < .001), E/E' ratio (p < .001), isovolumic relaxation time (IVRT) (p < .001), MPI (p < .001). Disease duration (odds ratio [OR]: 2.120 (1.023-1.703 95% confidence interval [CI]), p = .002), E' (OR:3.029 (1.013-1.703 95% CI) p = .004) and fQRS (OR:4.59 (1.94-10.87 95% CI), p = .001) were identified as the independent predictors of myocardial performance index (MPI). However, disease duration (OR:1.078 (1.030-1.128 95% CI), p = .001), E/E' (OR: 1.43 (1.22-1.97 95% CI), p = .001), IVRT (OR:1.65 (1.32-2.06 95% CI), p = .001) and MPI (OR:1.014 (1.004-1.024 95% CI), p = .002) were the independent predictors of fQRS.Conclusions: fQRS was frequent and an independent predictor of MPI that was independelty associated with LV dysfunction in patients with acromegaly. In light of these findings the presence of fQRS is thought to be an indicator of acromegalic CMP development.

Triphasic mitral flow pattern may indicate subclinical left ventricular systolic dysfunction.

PURPOSE: In this study, the presence and severity of left ventricular (LV) systolic dysfunction were investigated by speckle tracking echocardiography (STE) technique in patients with mitral triphasic mitral flow pattern (TMFP). The aim of the study was to evaluate the possible role of TMFP in the ethiopathogenesis of congestive heart failure. METHODS AND RESULTS: A total of 45 patients who were diagnosed with TMFP and 30 age- and gender-matched healthy volunteers were included in the study. The mean age in the study and control groups was 64 ± 12 and 62 ± 11 (P = .642), respectively. When echocardiographic parameters were evaluated, LV ejection fraction was found to be 63% ± 14 and 64 ± 12 (P = .745), in the study and control groups, respectively. LV end-diastolic and systolic diameters and LV mass index were also similar (P < .05). When LV diastolic parameters were compared, diastolic dysfunction was detected in 38 (84.4%) patients in the study population and 13 patients (43.3%) in the control group (P < .001). When STE findings were evaluated, both global longitidunal strain and global circumferential strain were significantly lower in the TMFP group when compared to controls (18.3 ± 1.7 vs 21.5 ± 1.5, P < .001 and 17.9 ± 1.6 vs 21.3 ± 2.1, P < .001, respectively). CONCLUSION: TMFP results in LV systolic dysfunction. Therefore, these patients may develop congestive heart failure in the long term. It will be rational that the patients with TMFP should be followed up more closely in terms of preventing manifest heart failure symptoms.

Effects of sacubutril/valsartan on nutritional status in heart failure with reduced ejection fraction.

BACKGROUND: Malnutrition commonly occurs in patients with heart failure with reduced ejection fraction (HFrEF). Sacubitril/valsartan, which is an AT1 neprilysin inhibitor, has been shown to reduce mortality and hospitalization in patients with HFrEF. However, its effects on nutritional status remain unclear. METHODS: Sacubitril/valsartan was initiated in 164 symptomatic patients with HFrEF receiving an optimal medical treatment with angiotensin inhibition (mean age: 63 ±â€Š20 years; 120 males, 60% ischemic cause). The New York Heart Association (NYHA) functional class and nutritional statuses of the patients were evaluated at the switching to AT1 neprilysin inhibitor and at the 6th-month follow-up of the maximum sacubitril/valsartan dose using the geriatric nutritional risk index (GNRI), controlling nutritional status (CONUT) score, prognostic nutritional index (PNI), and prealbumin. RESULTS: After the sacubutril/valsartan treatment, a significant reduction in the number (%) of malnourished patients was observed according to CONUT (before 47% vs. after 7%, P < 0.001), GNRI (before 39% vs. after 19%, P < 0.001), PNI scores (before 36% vs. after 12%, P = 0.002), and prealbumin (before 41% vs. after 12%, P < 0.001). Also significant changes were observed at the baseline and follow-up in the mean scores of the three different nutritional indexes and prealbumin levels [CONUT: 2.68 ±â€Š2.5, 1.02 ±â€Š1.0 (P < 0.001); GNRI: 97.1 ±â€Š9.7, 101.2 ±â€Š5.9 (P < 0.001); PNI: 38.8 ±â€Š4.8, 41.6 ±â€Š3.7 (P < 0.001); prealbumin: 14.6 ±â€Š6.9 mg/dl, 17.1 ±â€Š5.2 mg/dl (P < 0.001)]. Overall, the patients exhibited a significant functional improvement following the initiation of sacubitril/valsartan: 23% of the patients improved by two NYHA classes, 48% improved by one NYHA class, and 39% remained stable. CONCLUSION: In patients with HFrEF, the switch from angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker therapy to sacubitril/valsartan resulted in a significant improvement in both nutritional and functional statuses.

The prognostic value of altitude in patients with heart failure with reduced ejection fraction.

OBJECTIVE: It is well known that the altitude may affect the cardiovascular system. However, there were a few data related to the effect of altitude on the adverse outcome in patients with heart failure with reduced ejection fraction (HFREF). The aim of the present study was to investigate the role of intermediate high altitude on the major adverse cardiovascular outcome in patients with HFREF. METHODS: Patients with HFREF admitted to the outpatient clinics at the first center at sea level and the second center at 1890 m were prospectively enrolled in the study. HFREF was defined as symptoms/signs of heart failure and left ventricular ejection fraction <40%. The major adverse cardiac outcome (MACE) was defined as all-cause death, stroke, and re-hospitalization due to heart failure. The median follow-up period of the study population was 27 months. RESULTS: The study included 320 (58.55% male, mean age 65.7±11.2 years) patients. The incidence of all-cause death was 8.5%, stroke 6.1%, re-hospitalization due to decompensated heart failure 34.3%, and MACE 48.9%. In Kaplan-Meier analysis, patients with HFREF living at high altitude had more MACE (71.1% vs. 25.3%, log rank p=0.005) and presented with more stroke (11.3% vs. 2.1%, log rank p=0.001) and re-hospitalization due to heart failure (65.1% vs. 20.1%, log rank p<0.001) rates than those at low altitude in the follow-up; however, the rate of all-cause death was similar (9.4% vs. 8.1%, log rank p=0.245). CONCLUSION: In the present study, we demonstrated that the intermediate high altitude is the independent predictor of MACE in patients with HFREF. High altitude may be considered as a risk factor in decompensating heart failure.

Evaluation of left atrial volume and function by real time three-dimensional echocardiography in anemic patients without overt heart disease before and after anemia correction.

There are few data on the effects of low hemoglobine levels on the left atrium (LA) in anemic patients. Our aim was to evaluate left atrial (LA) volume and functions in anemic patients using real time three-dimensional echocardiography (RT3DE) and also to investigate changes in variables of LA after the correction of anemia. In total, 55 iron-deficiency anemia patients without traditional cardiovascular (CV) risk factors and 30 age- and gender-matched controls were studied. Assessments included history, physical examination and echocardiography. Of the 55 patients with anemia enrolled, 50 (39 females and 11 males 40.3 years) were followed and underwent echocardiography after correction of the anemia. LA maximum volume (LAVmax), LA minimal volume (LAVmin), LAVmax index (LAVI), before atrial contraction volume (LAVpreA), LA total emptying fraction, LA active emptying volume were higher in anemic patients. LA passive emptying fraction was significantly lower in anemic patients. Following correction of anemia, LA volume and function parameters were observed to be significantly reduced. Moreover, significant increase was noted in LA passive emptying fraction. Correlation analysis was performed and a significant negative correlation was noted between the percentage change in hemoglobin level and percentage change in LAVI (r = - 0.382, p = 0.003). It was shown that volume and functions of LA are impaired in anemic patients. However impaired parameters were improved after correction of anemia. It may be thought that RT3DE LA parameters can be used as an important preclinical marker of disease pathogenesis before developing heart failure or atrial arrhythmia.

Evaluation of left atrial volume and functions by real time three-dimensional echocardiography in patients with subclinical hypothyroidism before and after levothyroxine therapy.

BACKGROUND/AIMS: The cardiovascular system is one of the major targets of thyroid hormones. Subclinical hypothyroidism (SCH) is a common disease that can represent "early" thyroid failure. Our aim was to evaluate left atrial (LA) volume and functions in patients with SCH using real time three-dimensional echocardiography (RT3DE) and also to investigate changes in LA parameters after the levothyroxine treatment. METHODS: In total, 44 patients with SCH and 40 age- and gender-matched controls were studied. Assessments included history, physical examination and echocardiography. All patients with SCH were followed up with replacement therapy until the euthyroid status was achieved. RESULTS: In patients with SCH, LA total emptying volume, passive emptying volume, and passive ejection fraction were significantly reduced while LA minimal volume, active emptying volume, and active emptying fraction were significantly increased than in control group. Following the levothyroxine treatment, LA volume and function parameters were observed to be significantly improved. A negative correlation between the change of thyroid stimulating hormone (TSH) and change of LA active emptying volume and a positive correlation between the change of TSH level and change of LA passive emptying volume were found. CONCLUSION: It was shown that volume and functions of LA were impaired in patients with SCH. However, impaired parameters were improved after the levothyroxine treatment. These findings may be indicative of subclinical heart involvement that could lead to functional and structural changes in patients with SCH.

Usefulness of platelet to lymphocyte ratio for predicting recurrence of atrial fibrillation after direct current cardioversion.

OBJECTIVE: Atrial fibrillation (AF) is the most common cardiac rhythm disorder with the associated risks of stroke and mortality. The usefulness of platelet to lymphocyte ratio (PLR), a recently described inflammatory marker, in predicting adverse cardiovascular events has been demonstrated in several studies. In the current study, we investigated the role of PLR in predicting recurrence after successful electrical cardioversion (ECV) in patients with non-valvular persistent AF. METHODS: A total of 287 patients with non-valvular persistent AF achieving restoration of the sinus rhythm after successful ECV were included in this study. At study entry, complete blood count, routine biochemistry tests, and transthoracic echocardiography (TTE) were performed routinely in all subjects. Patients were followed up for 6 months following the procedure and comparisons were performed between patients who recurred and who maintained the sinus rhythm (SR). RESULTS: At 6 months of follow-up, AF recurred in 108 patients, corresponding to a recurrence rate of 39%. Mean PLR values in the "AF recurrence group" (mean age 57.4 ± 12.0 years, 47.6% [n = 80] female) and in "SR maintenance" group (mean age 65.0 ± 9.4 years, 55.6% [n = 60] female) were 184.8 ± 44.2 and 103.3 ± 44.2, respectively, with a significant difference between the two groups (p < 0.001). In multiple regression analyses, PLR emerged as a risk factor associated with AF recurrence during the 6-month follow-up period after successful ECV (odds ratio [OR]: 3.029 (1.013-9.055 95% confidence interval [CI]), p = 0.047). When a cutoff value of 147 was used, the sensitivity and specificity of PLR for predicting AF recurrence were 83.3% and 84.5%, respectively. CONCLUSION: Elevated PLR is a marker of increased inflammation and may serve as a practical and inexpensive predictor for recurrence during 6 months of follow-up in patients with non-valvular persistent AF who had restoration of the sinus rhythm after successful ECV.

Association between fragmented QRS complexes and left ventricular dysfunction in healthy smokers.

OBJECTIVE: Smoking is a known risk factor for cardiovascular diseases and may cause myocardial damage independently of coronary artery disease. Fragmented QRS (fQRS) is an important marker of myocardial fibrosis, while speckle-tracking echocardiography is a method used to show subclinical left ventricle dysfunction. METHODS: Our study included 230 healthy individuals aged 18-40 years. The patients included were separated into two groups: those smokers (n = 130) and non-smokers (n = 100). After that healthy smokers group were divided into two groups: those with fQRS (n = 24) and those without (n = 106). In both groups, the arithmetic mean of three images was used to obtain the left ventricle global longitudinal strain (LV-GLS). The E/SRe ratio was also calculated and analyzed. RESULTS: There were significant differences between the smokers and non-smokers in terms of, E/SRe (55.7 ± 17.9 vs 50.3 ± 14.8; P = 0.015), LV-GLS (23.1 ± 1.9 vs 24.0 ± 1.7; P = 0.001), and fQRS (18.5% vs 6%; P = 0.005). As a result of subgroup analysis, pack-year history was higher in the fQRS positive group (16.7 ± 3.7 vs 11.2 ± 3.7, P < 0.001). While a negative correlation was observed between pack-year history and LV-GLS (r = -0.678, P < 0.001), there was a positive correlation between pack-year history and E/SRe (r = 0.730, P < 0.001). CONCLUSION: In conclusion, our study demonstrated that fQRS is a parameter that can be used to determine left ventricle subclinical systolic and diastolic dysfunction in smokers, and that left ventricle dysfunction is related to the duration and intensity of smoking.
