Positive blood pressure response may predict the recovery of renal function after transcatheter aortic valve implantation.

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) may ameliorate renal function and increase blood pressure (BP). We aimed to investigate the association between increased BP and improved renal function (IRF) after TAVI. METHODS: A total of 176 patients who had undergone TAVI were evaluated retrospectively. BP records that were taken 24 h before and 72 h after TAVI were reviewed. Pre-procedural, post-procedural 48 h, and the first month estimated glomerular filtration rate (eGFR) levels were noted. IRF was accepted as a ≥ 10% increase in eGFR. The predictors of acute kidney injury (AKI) development at 48 h and IRF at 1 month were investigated. The association between mortality and BP response was assessed. RESULTS: A total of 157 patients were included in this study after exclusion as defined in the methodology. Mean age was 78.1 ±â€…7,1 and 51.6% were female. AKI occurred in 25.5% of patients and baseline eGFR and male gender were found as independent predictors for AKI development. IRF was observed in 16% at 48 h and 31.8% of patients at 1-month follow-up. Positive BP response was seen in 42% of patients. Pre-procedural chronic kidney disease, positive BP response, and an early increase in eGFR emerged as independent predictors of IRF at the first month. The patients with positive BP response were found to have decreased mortality at 710 days follow-up. CONCLUSION: Positive BP response after TAVI is related to improved survival and renal functions. The beneficial effect of TAVI on renal function may be precisely evaluated at 1st month rather than 48 h.

Predictive value of triglyceride/glucose index for cardiac outcomes in non-diabetic renal transplant recipients.

OBJECTIVES: Insulin resistance (IR) is associated with an increased risk of adverse cardiovascular outcomes. The triglyceride-glucose index (TyG index) is a reliable marker of IR. No study has examined the impact of the TyG index on major adverse cardiac and cerebrovascular events (MACCEs) in RTRs. Therefore, this study aimed to investigate the predictive value of the TyG index for MACCEs in RTRs. MATERIALS AND METHODS: Non-diabetic patients undergoing renal transplantation were retrospectively enrolled. The patients were divided into two groups according to MACCE development. The cut-off value of the TyG index for MACCE was conducted. RESULTS: The mean age of 522 patients was 41 (31-51) years, and 349 (66.9%) were male. During the 5.4-year follow-up, 84 (16%) MACCE were recorded. TyG index was significantly higher in the group that developed MACCE (p < 0,001). Cox regression analysis revealed that TyG index [HR: 3.297 (1.228-8.855), p = 0.018], left ventricle ejection fraction [HR: 0.934 (0.900-0.968), p < 0.001], cadaveric transplantation [HR: 8.886 (4.764-16.576), p < 0.001], graft survey [HR: 0.608 (0.542-0.682), p < 0.001)], and smoking [HR: 1.965 (1.117-3.456), p = 0.019] were independent predictors of MACCEs in nondiabetic RTRs. CONCLUSION: TyG index is an independent predictor of MACCEs in non-diabetic RTRs. The widespread use of the TyG index may positively affect long-term treatment costs and survival.

Value of systemic inflammation-response index in predicting contrast-induced nephropathy in patients with ST-elevation myocardial infarction.

BACKGROUND: Contrast induced nephropathy (CIN) is one of the feared complications of contrast medium-using procedures. Present study was conducted in order to evaluate the value of systemic inflammatory-response index (SIRI) for development of CIN among patients who underwent primary percutaneous intervention. METHODS: Six hundred seventy-six patients with the diagnosis of ST elevation myocardial infarction were included. The patients were divided into two groups according to the presence of CIN. Patients without (n = 530) and with (n = 146) CIN constituted group 0 and group 1, respectively. Clinical and biochemical features of the patients were recorded. Calculation of SIRI was made for each patient. RESULT: CIN patients were older, had higher prevalence of hyperlipidaemia, higher values of pre- and post-procedural creatinine levels, neutrophil and monocyte counts, neutrophil/lymphocyte ratio (NLR) and monocyte/lymphocyte ratio (MLR) and SIRI. They had lower values of left ventricular ejection fraction (LVEF), haemoglobin and high-density lipoprotein-cholesterol levels. SIRI had the highest area under the curve (AUC) for prediction of CIN. Pairwise analyses of the AUC's demonstrated that SIRI had statistically significantly higher AUC compared to NLR and MLR. Multivariate logistic regression analysis showed that besides from LVEF and pre-procedural creatinine, NLR and SIRI were the independent predictors of CIN. SIRI had a higher odds ratio compared to NLR. CONCLUSION: SIRI had greater diagnostic power than NLR and MLR and it can easily be used by physicians for the identification of high-risk patients for the occurrence of CIN.

Awareness and Knowledge of Pneumococcal Vaccination in Cardiology Outpatient Clinics and the Impact of Physicians' Recommendations on Vaccination Rates.

AIM: We aimed to evaluate the awareness of pneumococcal vaccination (PCV13, PPSV23) in general cardiology outpatient clinics and impact of physicians' recommendations on vaccination rates. METHODS: This was a multicenter, observational, prospective cohort study. Patients over the age of 18 from 40 hospitals in different regions of Turkey who applied to the cardiology outpatient clinic between September 2022 and August 2021 participated. The vaccination rates were calculated within three months of follow-up from the admitting of the patient to cardiology clinics. RESULTS: The 403 (18.2%) patients with previous pneumococcal vaccination were excluded from the study. The mean age of study population (n = 1808) was 61.9 ± 12.1 years and 55.4% were male. The 58.7% had coronary artery disease, hypertension (74.1%) was the most common risk factor, and 32.7% of the patients had never been vaccinated although they had information about vaccination before. The main differences between vaccinated and unvaccinated patients were related to education level and ejection fraction. The physicians' recommendations were positively correlated with vaccination intention and behavior in our participants. Multivariate logistic regression analysis showed a significant correlation between vaccination and female sex [OR = 1.55 (95% CI = 1.25-1.92), p < 0.001], higher education level [OR = 1.49 (95% CI = 1.15-1.92), p = 0.002] patients' knowledge [OR = 1.93 (95% CI = 1.56-2.40), p < 0.001], and their physician's recommendation [OR = 5.12 (95% CI = 1.92-13.68), p = 0.001]. CONCLUSION: To increase adult immunization rates, especially among those with or at risk of cardiovascular disease (CVD), it is essential to understand each of these factors. Even if during COVID-19 pandemic, there is an increased awareness about vaccination, the vaccine acceptance level is not enough, still. Further studies and interventions are needed to improve public vaccination rates.

Assessment of Systemic Immune-Inflammation Index and Systemic Inflammation-Response Index in Different Coronary Artery Plaque Types.

Coronary computed tomography angiography can evaluate coronary arterial plaque composition with high resolution. We aimed to determine and compare the values of systemic immune-inflammation index (SII) and systemic inflammation-response index (SIRI) in different plaque types. Highest values of SIRI and SII were found in mixed plaque type followed by non-calcified plaque type. SII value of 463.07 predicted one-year major adverse cardiac events (MACE) with a sensitivity of 72.7% and specificity of 64.3% and SIRI value of 1.14 predicted one-year MACE with a sensitivity of 93% and specificity of 62%. Paired analysis of area under the curve (AUC) of the receiver operating characteristic curves showed that SIRI had higher AUC than coronary calcium score and SII. Univariate logistic regression results showed that age, creatinine level, coronary calcium score, SII, and SIRI were the independent predictors of one-year MACE. According to the results of multivariate regression analysis, after adjusting other factors, age, creatinine level, and SIRI were the independent predictors of one-year MACE. SIRI seemed to improve the risk prediction in coronary artery disease. Therefore, special attention may need to be paid to patients who have a high SIRI.

C-Reactive Protein to Albumin Ratio as A Novel Inflammatory-Based Marker for 30-Day Mortality in Patients Undergoing Transcatheter Aortic Valve Replacement

Abstract Objective: We aimed to investigate whether C-reactive protein to albumin ratio (CAR) predicts the early and late mortality in patients undergoing transcatheter aortic valve replacement (TAVR). Methods: This study was retrospectively designed and includes 170 TAVR patients with a mean age of 78.4±7.1 years. Patients were divided into 2 groups as those who died and those who survived, taking into account the follow-up period. Complete blood count, serum CRP and serum albumin were obtained on admission. The CAR value of all patients was calculated and the relationship of CAR with early (≤30 days) and late mortality (>30 days) was evaluated. Results: The median follow-up period was 19 [7-31] months (maximum 66 months). Early mortality was observed in 20 (11.8%) patients, whereas late mortality was observed in 39 (22.9%) patients, most of them male (61.1%, P=0.04). Non-survivors had greater CAR value, higher baseline serum CRP level and lower baseline albumin level than survivors (P<0.01, for all parameters). According to multivariate analysis models, CAR (HR: 1.020, P<0.01) and TVAR score (HR: 1.294, P<0.01) were found to be independent predictors of early mortality while CRP and albumin were not. The area under the curve (AUC) for CAR was 0.73 with a P <0.01. A CAR >15.6 predicted the early mortality with 80% sensitivity and 57% specificity. Conclusion: The novel inflammatory marker CAR can be used as a reliable marker in predicting 30-day mortality in patients undergoing TAVR.

Long-Term Clinical Consequences of Patients Hospitalized for COVID-19 Infection.

BACKGROUND: Coronavirus disease 2019, putatively caused by infection with severe acute respiratory coronavirus 2, often involves injury to multiple organs and there are limited data regarding the mid- to long-term consequences of coronavirus disease 2019 after discharge from the hospital. The study aimed to describe the mid- to long-term consequences of coronavirus disease 2019 in hospitalized patients after discharge. METHODS: This single-center, prospective study enrolled coronavirus disease 2019 patients who were discharged uneventfully from our center. All participants underwent face-toface interviews by trained physicians and were asked to complete a series of questionnaires on third and sixth months' follow-up visits. RESULTS: A total of 406 consecutive discharged coronavirus disease 2019 patients were enrolled in this study. Patients were divided into 3 groups according to World Health Organization classification as follows: World Health Organization-3 (n=83); World Health Organization-4 (n=291); and World Health Organization-5,6 (n=32). Length of hospital stay was highly, significantly increased in the higher World Health Organization groups (World Health Organization-3 vs. World Health Organization-4, P < .0001; World Health Organization-3 vs. World Health Organization-5,6, P < .0001; World Health Organization-4 vs. World Health Organization-5,6, P < .0001), whereas the length of intensive care unit stay was highly, significantly increased only in World Health Organization-5,6 group compared to other groups (World Health Organization-3 vs. World Health Organization-5,6, P < .0001; World Health Organization-4 vs. World Health Organization-5,6, P < .0001). The most frequent complaints were chest pain (39%), and the frequency of complaints decreased during the 3-6 months follow-up period. Multiple logistic regression analysis indicated that age, coronary artery disease, fibrinogen, C-reactive protein, troponin I, D-dimer, use of steroid and/or low molecular weight heparin, and World Health Organization class were found to be independent predictors of ongoing cardiovascular symptoms. CONCLUSIONS: The current data demonstrated that persistent symptoms were common after coronavirus disease 2019 among hospitalized patients. This should raise awareness among healthcare professionals regarding coronavirus disease 2019 aftercare.

Predictors of Pacemaker-Induced Cardiomyopathy and Importance of Nutritional Status and Prognostic Nutritional Index.

Background: Long-term right ventricular (RV) pacing may cause progressive left ventricular systolic dysfunction, and malnutrition is related to adverse cardiovascular outcomes in patients with heart failure. We aimed to evaluate the relationship between immunonutritional status and the development of pacing-induced cardiomyopathy (PICMP). Methods: This study included 434 patients who underwent permanent pacemaker (PPM) implantation and had preserved left ventricular ejection fraction (LVEF) of > 40%. At six months of follow-up, the patients with LVEF < 40% were defined as having PICMP. Baseline prognostic nutritional index (PNI) was calculated based on serum albumin and lymphocyte count. Results: Overall, 16.5% of the our study patients developed PICMP. The PICMP group had more males (p = 0.013), lower baseline LVEF values (p = 0.014) and lower baseline PNI levels (p < 0.001). RV pacing ratios and paced QRS intervals were higher in the PICMP group (p < 0.001 for both), but the types of implanted pacemakers were similar for all patients (p = 0.709). According to regression analyses, baseline LVEF (p = 0.020), PNI (p < 0.001), C-reactive protein level (p = 0.012), RV pacing ratio (p < 0.001) and paced QRS interval (p = 0.001) were independent predictors of PICMP development. A cut-off PNI value ≤ 43.2 at the time of PPM implantation could predict PICMP development with a sensitivity of 85.5% and specificity of 86.7% (p < 0.001). Conclusions: Identifying poor nutritional status using the PNI may be an important concept to predict PICMP development, and optimizing nutritional status might help to reduce adverse outcomes in these patients.

The area under the curve (AUC) for CAR was 0.73 with a P <0.01. A CAR >15.6 predicted the early mortality with 80% sensitivity and 57% specificity. CONCLUSION: The novel inflammatory marker CAR can be used as a reliable marker in predicting 30-day mortality in patients undergoing TAVR.

Addition of the duration of ST segment depression to Duke treadmill score for diagnostic accuracy of exercise electrocardiography to predict obstructive coronary artery disease.

INTRODUCTION: Exercise electrocardiography (EET) is a safe and cost-effective method to predict the presence, prognosis, and severity of coronary artery disease (CAD). Various score models have been developed to increase predictive power of EET. In this study, we aimed to evaluate whether adding ST depression duration could have an effect on increasing the value of Duke treadmill score (DTS) in predicting obstructive CAD. METHODS: In this single centred, cross-sectional study, we evaluated a total of 258 patients who presented with a complaint of chest pain and undergone coronary angiogram in result of a positive EET. DTS was calculated for all the patients. The new score-revised DTS- was calculated by adding total ST depression time to classical DS parameters. We compared area under the curve (AUC) of DTS and revised DTS by Delongi method. RESULTS: Mean age of the group was 58.43 ± 9.37, and 37.2% (n = 96) were female. Mean total ST-depression duration was 171.72 ± 91.43 msec in normal artery group,241.54 ± 118.11 msec in non-obstructive CAD group, and 281.26 ± 113.64 in obstructive CAD group.ST-depression duration in both exercise and recovery, and total ST depression duration were significantly higher in obstructive CAD group than non-obstructive and normal artery groups (p = 0.024, p = 0.01, p < 0.01, and p < 0.01, respectively). Revised DTS had significantly higher predictive value of obstructive CAD compared to classical DS (AUC (95%CI): 0.744 vs. 0.626, p < 0.001). The AUC of DS was significantly lower than the new score (z-score:3.274, p = 0.011). CONCLUSION: In conclusion, adding ST depression duration to DTS calculation is increasing the discriminative value of DTS to predict obstructive CAD. Benefits of EET within the context of the management of CAD is well-known, hence, it is clear that physicians may use revised DTS.

Does coexistence of fragmented QRS and cardiovascular disease have the ability to predict the mortality in hospitalized, critically ill patients with COVID-19?

OBJECTIVE: In this study, we aimed to investigate the prognostic accuracy of the presence of fragmented QRS (fQRS) on baseline electrocardiogram on the adverse outcome in critical patients with coronavirus disease 2019 (COVID-19) with cardiovascular disease (CVD). METHODS: The current study was retrospective designed and included 169 patients who were critically ill with COVID-19 and CVD (mean age of 62±15 years). The patients were grouped into those who died (non-survivor group) and those who survived (survivor group). RESULTS: The non-survivors were older and more often had CVD (p=0.009), hypertension (p=0.046), diabetes (p=0.048), cancer (p=0.023), and chronic renal failure (p=0.001). Although the presence of fQRS on the basal electrocardiogram was more common in patients who died, this was not statistically significant (p=0.059). Furthermore, non-survivors had more frequent the coexistence of CVD and fQRS (p=0.029). In Model 1 multivariate regression analysis, CVD alone was not a predictor of mortality (p=0.078), whereas coexistence of CVD and fQRS was found to be an independent predictor of mortality in Model 2 analysis [hazard ratio (HR): 2.243; p=0.003]. Furthermore, older age (HR: 1.022; p=0.006 and HR: 1.023; p=0.005), cancer (HR: 1.912; p=0.021 and HR: 1.858; p=0.031), high SOFA score (HR: 1.177; p=0.003 and HR: 1.215; p<0.001), and increased CRP level (HR: 1.003; p=0.039 and HR: 1.003; p=0.027) independently predicted the mortality in both multivariate analysis models, respectively. CONCLUSION: fQRS may be a useful and handy risk-stratification tool for clinical outcomes by identifying high-risk individuals, especially among those with CVD.

Flight safety in patients with arrhythmia.

As it is comfortable, fast, and safe, an increasing number of patients with heart disease prefer to travel by flight. However, there is not much information about the problems that patients with arrhythmia may experience during air travel. In addition, the precautions to be taken with these patients during a flight are uncertain. In this review, the management of patients with cardiac conduction problems during flight was examined in detail.

Predicting One-Year Deaths and Major Adverse Vascular Events with the Controlling Nutritional Status Score in Elderly Patients with Non-ST-Elevated Myocardial Infarction Undergoing Percutaneous Coronary Intervention.

The prognostic value of malnutrition in elderly patients with non-ST-elevated myocardial infarction (NSTEMI) is not fully understood. Nutritional characteristics were evaluated by novel Controlling Nutritional status (CONUT), the prognostic nutritional index (PNI) and the geriatric nutritional risk index (GNRI) scores. The impact of these scores on major outcomes in 253 NSTEMI patients over 60 years and older were assessed. Compared to those with good nutritional status; malnourished patients had more major adverse cardiac and cerebrovascular events (MACCEs) at 1-year follow up. Multivariable cox regression analysis revealed that CONUT (hazard ratio = 1.372; p < 0.01) was independent predictor of MACCEs, whereas PNI (p = 0.44) and GNRI (p = 0.52) were not. The discriminating power of the CONUT (AUC: 0.79) was adequate and significantly superior to both the PNI (AUC: 0.68) and the GNRI (AUC: 0.60), with a p-value for both < 0.01. Patients with elevated CONUT exhibited the highest event rate for all-cause mortality and MACCEs in survival analysis (p < 0.01). We conclude that malnutrition is strongly associated with adverse outcomes in older patients with NSTEMI. In fact, the CONUT score adequately predicts one-year MACCEs among elderly NSTEMI patients who achieve complete revascularization after coronary intervention.

Human neutrophil peptides 1-3 level in patients with acute myocardial infarction and its relation with coronary artery disease severity.

OBJECTIVE: Inflammation plays a crucial role in the pathogenesis and clinical outcome of atherosclerosis. Among the various inflammatory factors, antimicrobial peptides, such as alpha-defensins, seem to contribute to the development and progression of atherosclerosis. The aim of this study was to evaluate the plasma levels of human neutrophil peptide-1, -2, and -3 (HNP1-3) in patients with acute myocardial infarction (AMI) and to assess its relationship with the severity of coronary artery disease. METHODS: lasma HNP1-3 levels in patients with AMI and controls with angiographically normal coronary arteries were measured by solid-phase enzyme-linked immunosorbent assay. In the patient group, coronary artery disease severity was assessed using the SYNergy between percutaneous intervention with TAXus and cardiac surgery score (SS). RESULTS: HNP1-3 levels were significantly higher in the group with AMI than in the controls (6.5±5.8 ng/mL vs. 2.8±2.5 ng/mL, p<0.001). The receiver operator characteristic (ROC) analysis yielded a cut-off value of 3.13 ng/mL for differentiating patients with AMI from the controls (area under the curve: 0.739, 95% confidence interval: 0.629-0.831, p<0.001). HNP1-3 levels in the high SS tertile (≥33) were slightly but statistically nonsignificantly higher than that in the low (≤22) and intermediate SS tertiles (high SS: 7.0±6.1 ng/mL, intermediate SS: 5.9±6.2 ng/mL, low SS: 5.3±3.8 ng/mL; p=0.639). CONCLUSION: Patients with AMI had higher plasma HNP1-3 levels than the controls, but this did not show a significant correlation with angiographic disease severity. The nonsignificant trend toward higher SS in patients with higher HNP1-3 levels warrants future studies on larger populations.

Neutrophil to lymphocyte ratio and platelet to lymphocyte ratio are associated with cryptogenic stroke in patients with patent foramen ovale.

INTRODUCTION: Although most ischaemic strokes are due to cardioembolism, about 25-40% of strokes are cryptogenic. Patent foramen ovale has been associated with cryptogenic stroke; however, the precise mechanism of this association has not been demonstrated. The aim of this study was to evaluate the association between inflammatory markers and cryptogenic stroke in patients with patent foramen ovale. MATERIAL AND METHODS: We included 206 patients with patent foramen ovale. Ninety-four (45.63%) out of 206 patients had had stroke, and 112 (54.37%) had not had stroke. The ratio of the total neutrophil count to the total lymphocyte count was defined as the neutrophil to lymphocyte ratio, and the ratio of the absolute platelet count to the absolute lymphocyte count was determined as the platelet to lymphocyte count. RESULTS: The neutrophil to lymphocyte ratio was significantly higher in patients who had stroke than in those who did not (2.41 ±1.69 vs. 2.19 ±1.74, p = 0.047). Although the platelet to lymphocyte count was also higher in patients who had had stroke than in those who had not, it was not statistically significant (120.94 ±55.45 vs. 118.01 ±52.21, p = 0.729). 1.62 was the cut-off value for neutrophil to lymphocyte ratio to be associated with stroke with 73.4% sensitivity and 45.05% specificity (p = 0.042). CONCLUSIONS: This study demonstrated that elevated neutrophil to lymphocyte ratio and platelet to lymphocyte count could be associated with cryptogenic stroke in patients with patent foramen ovale.

Coronary stent embolism to the right posterior cerebral artery.

A 57-year-old male was admitted to the emergency room with chest pain that has been present for 3 hours. His blood pressure was 70/50 mmHg and heart rate was 48 bpm. 12-lead surface electrocardiography revealed inferior myocardial infarction and third-degree atrioventricular (AV) block. An emergency coronary angiography showed a 50% stenosis in the middle segment of the left anterior descending artery and 90% in the proximal circumflex (Cx) artery. The right coronary artery was totally occluded. After the predilatation with a 2.0x15 mm compliant balloon at 10 atm, a 3.5x24 mm bare metal stent was implanted. The third-degree AV block improved and a sinus rhythm of 124 bpm was achieved, but hemodynamic stability was not attained. Percutaneous coronary intervention for the Cx artery was performed. Without predilatation, a 3.5x12 mm low profile BMS was easily advanced over the lesion. Just before the stent implantation, asystole developed, followed by convulsions. Blood pressure and heart rate recovered after the administration of 1 mg of atropine. However, during the seizure, the guidewire and coronary stent device fell to the aortic root. Stent struts were not seen on the balloon catheter in a fluoroscopic examination. Fluoroscopic scanning of the vascular system showed that the coronary stent was in the right posterior cerebral artery. There were no symptoms or signs of neurological disorder. Consultant invasive neuroradiologist recommended medical follow-up. Clopidogrel and acetylsalicylic acid were prescribed indefinitely. Two months after the primary PCI, a successful coronary artery bypass graft operation was performed. After 4 years, the patient remained without any symptoms of neurological problems.

Is there any association between rs1303 (Pi*M3) variant of alpha-1 antitrypsin gene and atrial septal aneurysm development?

AIM: Atrial septal aneurysm (ASA) is one of the congenital heart defects. The underlying pathophysiology of ASA has not been fully understood yet. Alpha-1 antitrypsin (A1AT) is a serine protease inhibitor glycoprotein, which is held responsible from tissue wall proteolysis if it is deficient in the body. The aim of this study was to investigate A1AT serum levels and the rs1303 (Pi*M3) variant in A1AT gene in patients with ASA. MATERIAL AND METHODS: Thirty patients (7 male and 23 female) with isolated ASA and 33 patients (11 male and 22 female) with normal atrial septum on echocardiography were included in this study. A1AT serum levels of study patients were measured quantitatively by the enzyme-linked immune sorbent assay (ELISA) method. The A1AT gene mutation rs1303 was analyzed by genotyping, which is performed on genomic DNA extracted from circulating mononuclear blood cells. Single-nucleotide polymorphism was evaluated on polymerase chain reaction using commercial kits. RESULTS: A1AT serum levels were not statistically different among patients with and without ASA (9.52 ± 4.33 µg/mL vs 9.83 ± 5.27 µg/mL, respectively, P = .80). A1AT homozygote mutation (PiM3M3) was significantly higher in the ASA group than the control group (21 vs 11, OR (95% CI): 6.68 [2.09-21.40], P = .001). A1AT serum levels were similar among patients with normal A1AT allele (PiMM), homozygote variant (PiM3M3), and heterozygote variant (PiMM3) (P = .79). CONCLUSION: This preliminary study revealed that homozygote A1AT rs1303 (PiM3M3) variant is significantly higher in patients with isolated ASA and may be associated with ASA development. Large scale comprehensive studies are needed to validate these results.

Effect of Septoplasty on Cardiopulmonary Functions in the Patients With Nasal Obstruction.

OBJECTIVE: In this study, the authors aimed to investigate whether septoplasty has an effect on cardiopulmonary functions in the patients with nasal obstruction. METHODS: A total of 53 patients with nasal obstruction due to septum deviation were included in the study. All the patients were performed septoplasty operation. Echocardiography and spirometric analysis were performed to assess cardiopulmonary functions before and after the operation (6 months postoperatively). The same evaluation was done for the degree of nasal obstruction by visual analogue scale. The preoperative and postoperative values were compared with each other. RESULTS: Of the total 53 patients, 44 were males (83%) and 9 were female (17%). The mean age was 31.71 ±â€Š9.46. The preoperative and postoperative mean right ventricular volumes were 2.0736 and 2.0906, respectively. The preoperative and postoperative mean left ventricular volumes were 4.4264 and 4.3528, respectively. The preoperative and postoperative mean cardiac septal thicknesses were 0.9642 and 0.9358, respectively. The mean value of preoperative cardiac posterior wall thicknesses was 0.8849, whereas the postoperative value was measured as 0.8340. The preoperative and postoperative mean pulmonary artery pressures were 27.8302 mmHg and 23.6415, respectively, and this was statistically significant (P < 0.001). The preoperative and postoperative mean forced vital capacities (FVC) were 4.3221 and 4.5564, respectively, and this was statistically significant (P < 0.001). The preoperative and postoperative mean 1st second forced expiratory volumes (FEV1) were 3.6698 and 3.8085, respectively, and this was statistically significant (P < 0.001). The mean value of preoperative FEV1/FVC was 84.9811, whereas postoperative mean value was measured as 83.8019 and this was statistically significant (P < 0.001). CONCLUSION: In this study, the authors observed that septoplasty has positive effect on cardiopulmonary functions in the patients with nasal obstruction due to nasal septum deviation. The authors also claim that septoplasty may be a preventive procedure for future pathologies of cardiopulmonary functions.

The relationship between grade of ischemia, success of reperfusion, and type of thrombolytic regimen.

BACKGROUND: This study was aimed to determine whether the grade of ischemia can predict the success of reperfusion in patients treated with thrombolytic therapy (TT) for ST elevation myocardial infarction (STEMI). MATERIAL AND METHODS: We enrolled 229 consecutive patients with diagnosis of STEMI and receiving TT. Patients were divided into 2 groups--grade 2 ischemia (GI2) and grade 3 ischemia (GI3)--according to initial electrocardiogram (ECG). As TT, fibrin-specific (tissue plasminogen activator (t-PA)) or non-fibrin-specific (streptokinase (SKZ)) regimens were used. Successful reperfusion was defined as >50% resolution of the maximal ST segment on 90-min ECG. We tried to evaluate whether the grade of ischemia could predict the success of reperfusion and if there were any differences in terms of successful reperfusion between different thrombolytic regimens. RESULTS: The successful reperfusion rate was significantly higher in GI2 than GI3 (82.4% vs. 64.4% respectively, p=0.002). The success rate was lowest at anterior GI3 (55.8%). Although there was no significant difference between thrombolytic regimens in all groups (p=0.77), t-Pa was superior to SKZ in anterior GI3 (63,6% vs. 30%, p=0.061). In addition, in multivariate analysis, GI and infarct localization were found as independent predictors for successful reperfusion with TT (p=0.006 and p=0.042, respectively). CONCLUSIONS: In the current study, we found that GI2 is an independent predictor for successful reperfusion in STEMI treated with TT. Fibrin specific regime should be preferred in anterior GI3.
