Effect of the Prognostic Nutrition Index on Long-Term Outcomes in Unprotected Left Main Coronary Artery Revascularization.

Objective    The prognostic nutritional index (PNI) is a practical, applicable, prognostic scoring system. However, its clinical significance in unprotected left main coronary artery (ULMCA) patients undergoing percutaneous coronary intervention (PCI) has not yet been clarified. This study aimed to examine the relationship between malnutrition as assessed by PNI and major adverse cardiac events (MACE) in ULMCA patients undergoing PCI.Material and methods    185 patients who were hospitalized in our clinic underwent coronary angiography, had a critical LMCA lesion, and underwent angiography-guided PCI were included. The study population was divided into tertiles based on the PNI values. A high PNI (n=142) was defined as a value in the third tertile (≥ 34.0), and a low PNI (n=43) was defined as a value in the lower 2 tertiles (< 34.0). The primary endpoint was MACE.Results    MACE and mortality rates in the low PNI group were significantly higher compared to the high PNI group (51 % vs. 30 %, p=0.009; 44 % vs. 20 %, p=0.002, respectively). High PNI (HR:1.902; 95 % CI:1.112-3.254; p=0.019), previous stroke (HR:3.025; 95 % CI:1.038-8.810; p=0.042) and SYNTAX score (HR:1.028; 95 % CI:1.004-1.057, p=0.023) were independent predictors of MACE in the multivariable cox regression analyzes.Conclusions    In patients undergoing ULMCA PCI, nutritional status can be considered an indicator of MACE rates by evaluating the PNI score. This index can be used for risk classification.

Dependence of clinical outcomes on time of hospital admission in patients with ST-segment elevation myocardial infarction.

BACKGROUND: There are conflicting results in studies investigating the effects of percutaneous coronary intervention (PCI) on the prognosis of patients with ST-segment elevation myocardial infarction (STEMI) during or outside of usual hospital working hours. While some researchers have reported higher mortality rates in STEMI patients admitted outside of working hours, others did not find a statistically significant difference. OBJECTIVES: Investigate the short-term endpoints and long-term outcomes of STEMI patients by time of admission. DESIGN: Retrospective SETTING: Tertiary percutaneous coronary intervention center. PATIENTS AND METHODS: Patients were grouped by admission, which consisted of four intervals: 06:00 to <12:00, 12:00 to <18:00, 18:00 to <24:00, and 24:00 to <06:00. We analyzed demographic, clinical and mortality by admission time interval and mortality by multivariate analyses, including the time intervals. MAIN OUTCOME MEASURES: Clinical data and mortality SAMPLE SIZE: 735 patients; median (IQR) age 62 (22) years; 215 (29.3%) women. RESULTS: Patients admitted at night were 1.37 times more likely to experience pulmonary edema than patients whose symptoms started in the daytime (P=.012); 32.9% of the patients whose symptoms started at night presented with Killip class II-IV, while during the daytime, 21.4% presented with Killip class II-IV (P=.001). Among the patients, the most common was inferior STEMI (38.6%). However, no-reflow was significantly higher during the daytime compared to the nighttime (P=.12). The risk of the cardiac arrest on admission was 1.2 times higher in patients admitted at night (P=.034). Neither time interval of admission nor several other variables had an effect on clinical outcome or mortality. CONCLUSIONS: While patients admitted at night presented with pulmonary edema and cardiogenic shock more frequently, no reflow was observed during the day after the procedure. Although patients admitted at night with STEMI presented with worse clinical conditions, similar results were observed between the groups in clinical outcomes. LIMITATIONS: More "real world" results might have been obtained if the study had replicated more typical referral conditions for PCI. CONFLICT OF INTEREST: None.

A new trend to reduce adverse events in patients undergoing transcatheter aortic valve implantation: cusp overlap technique: a cross sectional study.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is currently the treatment of choice for the majority of patients at moderate or high surgical risk. However, some complications occur frequently with this procedure. In this study, we aimed to assess whether the cusp-overlap view (COP) technique may be associated with a reduced incidence of some of these complications compared with the classical three-cusp view (TCV) technique. METHODS: In this single-center, retrospective study we investigated; technical success, postprocedural permanent pacemaker implantation (PPMI), new-onset stroke, pericardial tamponade, arrhythmia development, acute renal failure, major bleeding, major vascular complications, procedure-related coronary obstruction, new-onset left bundle branch block (LBBB), paravalvular leak, peri-procedural myocardial infarction (MI), day of hospitalization, death, and major adverse cardiac and cerebrovascular events (MACCE) were determined as the clinical endpoints. RESULTS: A total of 281 consecutive patients who met the study criteria and underwent elective or emergency transfemoral TAVI using the self-expandable CoreValve Evolut valve were included. 176 consecutive patients implanted with the classical TCV technique and 105 consecutive patients implanted with the COP technique were compared. Compared with the TCV group, patients in the COP group had lower PPMI (3.8% vs. 10.8%, p = 0.039), in-hospital mortality (1.9% vs. 8.5%, p = 0.018), and 1-year death (4.8% versus 18.8%, p = 0.001), and MACCE rates (12.4% vs 31.3%, p < 0.001). CONCLUSION: The COP technique may help to reduce the conduction disturbances, PPMI requirement and complication rates that may develop following TAVI. In addition, it is an interesting result that it reduces mortality and MACCE rates in long-term follow-ups.

A novel predictor in endovascular treatment patients for cerebral perfusion and prognosis: CHA2DS2-VASC.

OBJECTIVE: Thrombolysis in Cerebral Infarction(TICI) score is used to objectively evaluate cerebral perfusion after intervention in acute stroke with mechanical thrombectomy. In our study, we aimed to compare the results of patients with successful TICI perfusion score (TICI ≥ 2c) with the results of patients with poor TICI perfusion score (TICI < 2c) and to investigate the relationship of the CHA2DS2-VASc scoring system with the final TICI perfusion score and other endpoints. METHODS: For this retrospective, single-center, cross-sectional study, 278 patients who underwent endovascular thrombectomy were screened consecutively by the interventional neurology department of hospital. The primary endpoint of the study was in-hospital and 1-year all-cause death. All patients underwent cranial imaging to evaluate hemorrhagic transformation after the procedure. RESULTS: It was observed that CHA2DS2-VASc score was significantly higher in the poor cerebral perfusion group than in the succesful cerebral perfusion group (3.19 ± 1.8 vs 2.72 ± 1.73, p = 0.046). According to Kaplan Meier's analysis, a significant difference was observed in the group with a CHA2DS2-VASc score > 2.5 in terms of all-cause mortality at follow-up compared to the group with a low CHA2DS2-VASc score (p = 0.002). According to Kaplan Meier's analysis, a significant difference was observed in the group with a poor TICI score compared to the group with a succesful one in terms of all-cause mortality at follow-up (p < 0.001). Cox regression model showed that poor TICI score group, Age ≥ 75 years, lower glomerular filtariton rate (GFR), higher high-sensitiveC-reactiveprotein (Hs-CRP), and higher admission NIHSS score were independent predictors of 1-year all-cause mortality. CONCLUSION: High CHA2DS2-VASc score has been shown to be a predictor of unsuccessful cerebral perfusion score and 1-year mortality after mechanical thrombectomy in stroke patients. As a result of our research, it has been shown that complete or nearly complete reperfusion has more positive results than partial reperfusion.

Novel predictor of pulmonary arterial hypertension: Monocyte to HDL cholesterol ratio.

Monocyte to HDL cholesterol ratio (MHR), lymphocyte to monocyte ratio (LMR), and neutrophil to lymphocyte ratio (NLR) have been proposed as novel systemic inflammatory markers. The aim of this study was to explore the association between MHR, LMR and NLR with pulmonary arterial hypertension (PAH). The study is a single-center, retrospective Cross-sectional study. The study group consisted of 73 patients with PAH and the control group 77 participants without cardiac pathology as determined by echocardiography. On admission, blood sampling to calculate MHR, LMR, NLR, and detailed clinical data were obtained. According to the Pearson test, systolic pulmonary artery pressure (PAP) value Higher MHR, NLR and lower LMR that indicates an enhanced inflammation were significantly increased in patients with PAH when compared with controls. Compared to many other inflammatory markers, these markers are widely available. positively correlated with the MHR and NLR (r:.35, P < .001 and r:.33, P < .001, respectively), but negatively correlated with LMR (r: -.26, P = .001). After multivariate logistic regression analysis, MHR, LMR, and NLR remained as significant predictors of PAH (OR: 2.651, 95% CI: 1.227-5.755, P = .007; OR: 0.647, 95% CI:0.450-0.931, P = .005; OR: 1.350, 95% CI: 1.054-1.650 P = .030, respectively).

Oral Anticoagulant Use and Long-Term Follow-Up Results in Patients with Non-valvular Atrial Fibrillation in Turkey AFTER-2 Study.

BACKGROUND: The aim of this study was to investigate the frequency of oral anticoagulant drugs and time in therapeutic range in patients receiving warfarin in addition to the epi-demiological trial of non-valvular atrial fibrillation previously conducted in Turkey (The Atrial Fibrillation: Epidemiological Registry trial). Furthermore, the prevalence of major adverse events and mortality rates of the patients were evaluated during the long-term follow-up period. METHODS: We created a national data registry for non-valvular atrial fibrillation patients, reflecting all geographic regions by population density. In that context, the study included all consecutive atrial fibrillation patients older than 18 years of age who were admitted to the cardiology outpatient clinic except for patients those with prosthetic heart valvesand rheumatic mitral valve stenosis. RESULTS: This study included 2592 patients from 35 different centers. The mean age was 68.7 ± 11.1 years, and 55.5% of the patients were female. The most common comorbid diseases were chronic kidney disease (69%) and hypertension (65.5%). The time in ther- apeutic range rate in the general population was 40%, and the mortality rate at 5-year follow-up was 29.4%. CONCLUSION: The Atrial Fibrillation: Epidemiological Registry 2 study showed higher use of anticoagulant in non-valvular atrial fibrillation patients than in previous national stud-ies. Furthermore, this study demonstrated that most of the non-valvular atrial fibrilla- tion patients are in the high-risk group and the time in therapeutic range rates are still low in Turkey. As a result, this is a significant reason for switching from warfarin to non-K vitamin-dependent new oral anticoagulant treatments.

Comparison of long-term outcome of patients with ST-segment elevation myocardial infarction between pre-COVID-19 and COVID-19 era.

AIMS: To compare major cardiovascular and cerebrovascular events (MACCE) rates between patients in the pre-COVID-19 era and COVID-19 era, and to assess the impact of the presence of COVID-19 (+) on long-term MACCE in ST-segment elevation myocardial infarction (STEMI) in Turkey. METHODS: Using the TURSER study (TURKISH ST-segment elevation myocardial infarction registry) data, the current study included 1748 STEMI patients from 15 centres in Turkey. Patients were stratified into COVID-19 era (March 11st-May 15st, 2020; n = 723) or pre-COVID-19 era (March 11st-May 15st, 2019; n = 1025) cohorts. Long-term MACCE rates were compared between groups. In addition, the effect of COVID-19 positivity on long-term outcomes was evaluated. The primary outcome was the occurrence of MACCE at long-term follow-up, and the secondary outcome was hospitalization with heart failure. RESULTS: The MACCE and hospitalization with heart failure rates between pre-COVID-19 era and COVID-19 era were 23% versus 22% (p = .841), and 12% versus 8% (p = .002), respectively. In the COVID-19 era, the rates of MACCE and hospitalization with heart failure COVID-19-positive versus COVID-19-negative patients were 40% versus 20%, (p < .001), and 43% versus 11% (p < .001), respectively. CONCLUSION: There was no difference between the pre-COVID-19 era and the COVID-19 era in terms of MACCE  in STEMI patients in Turkey. In the COVID-19 era, STEMI patients positive for COVID-19 had a higher rate of MACCE and heart failure hospitalization at the long-term follow-up.

Impact of COVID-19 outbreak on patients with ST-segment elevation myocardial infarction (STEMI) in Turkey: results from TURSER study (TURKISH St-segment elevation myocardial infarction registry).

OBJECTIVE: We aimed to investigate both the impact of COVID-19 pandemic on ST-segment elevation myocardial infarction (STEMI) admission, and demographic, angiographic, procedural characteristics, and in-hospital clinical outcomes of patients with COVID-19 positive STEMI in Turkey. METHODS: This was a multi-center and cross-sectional observational study. The study population included 1788 STEMI patients from 15 centers in Turkey. The patients were divided into two groups: COVID-19 era (March 11st-May 15st, 2020; n = 733) or pre- COVID-19 era group (March 11st-May 15st, 2019; n = 1055). Also, the patients in COVID-19 era were grouped as COVID-19 positive (n = 65) or negative (n = 668). RESULTS: There was a 30.5% drop in STEMI admission during COVID-19 era in comparison to pre-COVID-19 era. The patients admitted to the medical centers during COVID-19 era had a longer symptom-to-first medical contact time [120 (75-240) vs. 100 (60-180) minutes, p < 0.001]. COVID-19 positive STEMI patients had higher thrombus grade and lower left ventricular ejection fraction compared to COVID-19 negative patients. COVID-19 positive patients had higher mortality (28% vs. 6%, p < 0.001) and cardiogenic shock (20% vs. 7%, p < 0.001) rates compared with those without COVID-19. Matching based on propensity scores showed higher mortality and high thrombus grade in STEMI patients who were infected by SARS-COV-2 (each p < 0.05). CONCLUSIONS: We detected significantly lower STEMI hospitalization rates and significant delay in duration of symptom onset to first medical contact in the context of Turkey during the COVID-19 outbreak. Moreover, high thrombus grade and mortality were more common in COVID-19 positive STEMI patients.

Monocyte to high-density lipoprotein cholesterol and lymphocyte to monocyte ratios are predictors of in-hospital and long-term mortality in patients with acute coronary syndrome.

OBJECTIVE: We aimed to determine the relationship between LMR and MHR and in-hospital and long-term mortality in patients with ACS. METHODS: We retrospectively collected patients with ACS undergoing coronary angiography between January 2012 and December 2013. RESULTS: In total, 825 patients with a mean age of 62.4 ± 12.9 years (71.3% male) were enrolled in the study. Patients were divided into three tertiles based on MHR levels and LMR levels. In-hospital mortality of the patients was significantly higher amongst patients in the upper MHR tertile when compared with the lower and middle MHR tertile groups [30 (10.9%) vs 8 (2.9%) and 14 (5.1%); P < .001, P = .009, respectively]. Five-year mortality of the patients was significantly higher amongst patients in the upper MHR tertile when compared with the lower and middle MHR tertile groups [84 (30.5%) vs 48 (17.5%) and 57 (20.7%); P < .001, P = .005, respectively]. In-hospital mortality of the patients was significantly higher amongst patients in the lower LMR tertile when compared with the upper and middle LMR tertile groups [25 (9.1%) vs 10 (3.6%) and 17 (6.2%); P = .007, P = .130, respectively]. Five -year mortality of the patients was significantly higher amongst patients in the lower LMR tertile when compared with the upper and middle LMR tertile groups [77 (28.0%) vs 47 (17.1%) and 65 (23.6%); P = .001, P = .142, respectively]. CONCLUSION: We have shown that high MHR and low LMR were significant and independent predictors of in-hospital and long-term mortality in patients with ACS.
