The right ventricle outflow tract (RVOT) location is favorable for performing zero-fluoroscopy CA. Non-RVOT zero-fluoroscopy CA is a challenging procedure. The study aimed to evaluate the efficacy and safety of zero-fluoroscopy CA using the EAM in patients with PVCs from RVOT and non-RVOT. METHODS: Completely zero-fluoroscopy CA of PVCs guided by EAM was performed in 107 patients with PVCs. 54 patients underwent zero-fluoroscopy RVOT CA. The remaining 53 patients underwent zero-fluoroscopy non-RVOT CA. Demographic and clinical baseline characteristics, procedure parameters, and follow-up were obtained from medical records. Primary outcomes were the acute and the permanent success rate (12-month follow-up), complications, and procedure time. RESULTS: There were no significant differences between groups regarding baseline characteristics. Acute procedural success was achieved in 52 patients (94,44%) in the RVOT zero-fluoroscopy CA group and in 45 patients (86,54%) in the non-RVOT zero-fluoroscopy CA group (ns). A long-term success rate was achieved in 50 patients (90,74%) in the RVOT zero-fluoroscopy CA group and in 44 patients (84,62%) in the non-RVOT zero-fluoroscopy CA group (ns). The median procedure time was 80.5 minutes in the RVOT group and 90 minutes in the non-RVOT group (ns). There were two complications in the non-RVOT group (ns). CONCLUSIONS: There were no differences in procedure time efficacy and safety zero-fluoroscopy ablation between RVOT and non-RVOT locations. Non-fluoroscopy CA of PVCs is a feasible, safe, and efficient procedure.

Using CEE-specific procedure data, the present study modeled cryoballoon ablation procedures on EP lab resource consumption to improve efficiency. METHODS: A discrete event simulation model was developed to assess EP efficiency with cryoballoon ablation. Model inputs were taken from CEE sites within the Cryo Global Registry, namely Czech Republic, Hungary, Poland, Serbia, and Slovakia. The main endpoints were percentage of days that resulted in overtime and percentage of days with time for one extra simple EP procedure. Use of the 'figure of 8' (Fo8) closure technique to reduce procedure time was also examined. RESULTS: The mean lab occupancy time across all CEE sites was 133 ± 47 minutes (min: 104 minutes, max:181 minutes). Cryoballoon ablation in the base-case scenario resulted in 14.6% of days with overtime and 64.8% of days with time for an extra simple EP procedure. Use of the Fo8 closure technique enhanced these values to 5.5% and 85.3%, respectively. Model endpoints were most sensitive to changes in lab occupancy times and overtime start time. CONCLUSIONS: In this CEE-specific analysis of EP lab efficiency it was found that 3 cryoballoon ablation procedures could be performed in 1 lab day, leaving time for a 4th simple EP procedure on most days. As such, use cryoballoon ablation for PVI is an effective way to improve EP lab efficiency.

Thus, a comparison of the 3-year clinical outcomes between the DM and non-DM groups among patients with MINOCA was undertaken. METHODS: From the Korea AMI Registry-National Institute of Health dataset, 10,774 AMI patients were enrolled. After applying the exclusion criteria, 379 patients with MINOCA were included. The primary clinical outcomes were major adverse cardiac and cerebrovascular events (MACCE), defined as all-cause death, recurrent myocardial infarction (MI), repeat coronary revascularization, and stroke. The secondary outcomes were the individual components of MACCE. RESULTS: The adjusted hazard ratios for 3-year MACCE (2.287, p = 0.010), all-cause death (2.845, p = 0.004), and non-cardiac death (non-CD, 3.914, p = 0.008) were higher in the DM group than in the non-DM group. It is speculated that the higher non-CD rate in the MINOCA group is attributable to a higher proportion of patients with non-ST-segment elevation MI in the total study population. The CD, recurrent MI, revascularization, and stroke rates were similar between the DM and non-DM groups. DM, advanced age, cardiopulmonary resuscitation on admission, and non-use of statin medications were significant predictors of MACCE. CONCLUSIONS: In this study involving patients with MINOCA, the DM group exhibited a higher 3-year mortality rate than the non-DM group. Thus, DM demonstrated a hazardous effect even in patients with MINOCA.

Herein, the aim was to assess the etiology and degree of MR in an unselected TAVI population and investigate the impact of MR reduction at mid-term follow-up. METHODS: Patients subjected to TAVI as a treatment for severe AS in a single center were retrospectively analyzed. The primary endpoint was the MR reduction after TAVI. The secondary endpoint was all-cause mortality and heart failure hospitalization at a 3-year follow-up. RESULTS: Patients undergoing TAVI (n = 283) in the years 2017-2019 were screened for the presence of hemodynamically significant MR. Sixty-nine subjects (24.4%) with severe (16, 23.2%) and moderate (53, 76.8%) MR were included. The primary MR was predominant (39 subjects, 56.5%). The median age of the patients was 82 years. MR improved in 25 patients (36.2%, p < 0.001). Baseline severe MR was more prone to reduce (8 subjects, 50%) than moderate (17 subjects, 32.1%, p = 0.04). The primary MR improved in 14 patients (35.9%), while secondary in 11 patients (36.7%, p = 1). Patients showing MR reduction had lower mortality (8 vs. 29.55%, p = 0.047) and were less frequently hospitalized (20 vs. 45.45%, p = 0.03) at 3-year follow-up. CONCLUSIONS: Hemodynamically significant MR improves after TAVI regardless of its etiology. Moreover, MR reduction after TAVI is associated with better clinical outcomes.

This decline may be attributed to higher mortality among exposed individuals, lifestyle, or natural physiological changes related to age. Only prospective observations at the individual level provide credible insights of exposure during the transition from middle to old age. This study addresses changes in cardiovascular risk factors among older urban residents in Poland over an 18-year period. METHODS: The study analyzed data from the Polish arm of the Health, Alcohol and Psychosocial factors In Eastern Europe (HAPIEE) project, a prospective cohort study investigating cardiovascular disease determinants. The sample included 312 participants (46-69 years). Data on demographic characteristics, blood lipids, blood pressure, body mass index (BMI), fasting glucose, and smoking status were collected at baseline and during re-examination. RESULTS: The analysis yielded a decrease in diastolic blood pressure, total cholesterol, LDL-cholesterol, and non-HDL cholesterol concentrations. However, BMI and fasting glucose levels increased. The decrease in blood pressure was mainly attributed to treatment effects, while the reduction in lipid concentrations was observed regardless of treatment. In addition, smoking prevalence decreased over the course of 18 years. CONCLUSIONS: The results of the prospective nearly 20 year observation at the individual level confirm findings from repeated cross-sectional studies on decrease in lipid concentrations, blood pressure and prevalence of smoking in older individuals.

This retrospective study aimed to assess the effect of preoperative diagnosis of locomotive disorders requiring the continuous use of orthopedic devices on postoperative rehabilitation and stable sternum adhesion. MATERIAL AND METHODS: The study included 122 patients who underwent cardiac surgery, with 68 patients in the study group having a musculoskeletal disorder and 54 patients in the control group without such disorders. Preoperative demographic, clinical, and laboratory data as well as postoperative rehabilitation and sternum adhesion were evaluated. RESULTS: The results showed that patients in the study group had lower levels of calcium (p < 0.001), vitamin D (p < 0.001), and creatine kinase (p = 0.022) prior to the surgery. In the early postoperative period, 8 patients from the study group and 4 from the control group required reoperation due to sternal instability (p = ns). In the late postoperative period, sternal instability was present in 2 patients from the study group and 3 from the control group (p = ns). The survey study revealed a significantly better (p = 0.029) evaluation of postoperative rehabilitation among the study group patients. CONCLUSIONS: Overall, the results indicated that a preoperative locomotive disorder has no significant impact on sternal instability in the early or late postoperative periods. However, patients with such disorders have a better understanding of the importance, purpose, and course of rehabilitation after cardiac surgery and exhibit lower levels of calcium, vitamin D, and creatinine.

Most patients with that stage of chronic kidney disease (CKD) are eligible for renal replacement treatment, which includes kidney transplantation, hemodialysis and peritoneal dialysis. It is well recognized that CKD raises the risk of cardiovascular disease and is linked to a higher cardiovascular death rate in this population. Additionally, the largest risk of cardiovascular events is seen in ESRD patients. Heart failure (HF) and dangerous arrhythmias, which are more common in the advanced stages of CKD, are two additional causes of cardiovascular death in addition to atherosclerosis-related complications such as myocardial infarction and stroke. In this review the significance of natriuretic peptides and other HF biomarkers in hemodialysis patients, as tools for cardiovascular risk assessment will be discussed.

However, the optimal therapeutic strategy of nonculprit lesions remains unknown. Murray law-based Quantitative Flow Ratio (μQFR) is a novel, non-invasive, vasodilator-free method for evaluating the functional severity of coronary artery stenosis, which has potential applications for nonculprit lesion assessment in STEMI patients. MATERIAL AND METHODS: Patients with STEMI who received staged PCI before hospital discharge were enrolled retrospectively. μQFR analyses of nonculprit vessels were performed based on both acute and staged angiography. RESULTS: Eighty-four patients with 110 nonculprit arteries were included. The mean acute μQFR was 0.76 ± 0.18, and the mean staged μQFR was 0.75 ± 0.19. The average period between acute and staged evaluation was 8 days. There was a good correlation (r = 0.719, P < 0.001) between acute μQFR and staged μQFR. The classification agreement was 89.09%. The area under the receiver operator characteristic (ROC) curve for detecting staged μQFR ≤ 0.80 was 0.931. CONCLUSIONS: It is feasible to calculate the μQFR during the acute phase of STEMI patients. Acute μQFR and staged μQFR have a good correlation and agreement. The μQFR could be a valuable method for assessing functional significance of nonculprit arteries in STEMI patients.

This study investigated the impact of heart rate and its change on the recovery of left ventricular ejection fraction (LVEF) in heart failure with reduced ejection fraction (HFrEF). MATERIAL AND METHODS: From 398 outpatients who had a history of hospitalisation for heart failure, 138 subjects diagnosed as HFrEF (LVEF < 40%) on heart failure hospitalisation were enrolled and longitudinally surveyed. During follow-up periods more than one year, 64 and 46 patients were identified as HFrecEF (improved LVEF to ≥ 40% and its increase of ≥ 10 points) and persistent HFrEF, respectively. RESULTS: In the overall subjects, the reduction of heart rate through the observation periods was closely correlated with the improvement of LVEF (r = -0.508, p < 0.001). Heart rate on hospital admission for heart failure was markedly higher in patients with HFrecEF (112 ± 26 bpm) than in those with persistent HFrEF (90±18 bpm). Whereas heart rate at the first outpatient visit after discharge was already lower in the HFrecEF group (80 ± 13 vs. 85 ± 13 bpm in the persistent HFrEF group). A multivariate logistic regression analysis revealed that the decrease in heart rate from admission to the first visit after discharge was a significant determinant of HFrecEF (p < 0.001), independently of confounding factors such as ischemic heart disease and baseline LVEF and left ventricular dimension. CONCLUSIONS: Our findings suggest that heart rate reduction in the early phase after heart failure onset is a powerful independent predictor of the subsequent recovery of LVEF in HFrEF patients.

Several predictors for impaired prognosis have been identified. However, with machine learning (ML) approaches, certain phenotypes may be confined to classify the affected population and to predict outcome. This study aimed to phenotype patients using unsupervised ML technique within the International Postgraduate Course Heart Failure Registry for patients hospitalized with COVID-19 and Cardiovascular disease and/or RF (PCHF-COVICAV). MATERIAL AND METHODS: Patients from the eight centres with follow-up data available from the PCHF-COVICAV registry were included in this ML analysis (K-medoids algorithm). RESULTS: Out of 617 patients included into the prospective part of the registry, 458 [median age: 76 (IQR:65-84) years, 55% male] were analyzed and 46 baseline variables, including demographics, clinical status, comorbidities and biochemical characteristics were incorporated into the ML. Three clusters were extracted by this ML method. Cluster 1 (n = 181) represents mainly women with the least number of overall comorbidities and cardiovascular RF. Cluster 2 (n = 227) is characterized mainly by men with non-CV conditions and less severe symptoms of infection. Cluster 3 (n=50) mainly represents men with the highest prevalence of cardiac comorbidities and RF, more extensive inflammation and organ dysfunction with the highest 6-month all-cause mortality risk. CONCLUSIONS: The ML process has identified three important clinical clusters from hospitalized COVID-19 CV and/or RF patients. The cluster of males with severe CV disease, particularly HF, and multiple RF presenting with increased inflammation had a particularly poor outcome.

The aim was to compare the patient profile, ACS characteristics, and the outcomes in patients referred to the invasive cardiology department before (March 2019 - February 2020) and during the COVID-19 pandemic (March 2020 - February 2021). METHODS: Clinical and demographic features, comorbidities, laboratory parameters at admission, and periprocedural data were recorded. The relationship of these parameters with in-hospital mortality was assessed. RESULTS: Before the COVID-19 pandemic, 664 patients were admitted due to ACS (mean age 67.16 ± 11.94 years, females 32.1%), and during the COVID-19 pandemic 545 ACS patients were recorded [mean age 66.02 ± 12.02 years (p = 0.463), females 31% (p = 0.706)]. A 17.8% decrease in the ACS rate was observed. During the pandemic, there were more STEMI patients (44.3% vs. 52.1%, p < 0.001) and fewer patients treated conservatively (24.9% vs. 8%, p < 0.001). Most lesions were located in the left anterior descending artery (53.4% vs. 54.7%), but post-percutaneous coronary intervention TIMI 3 was observed more frequently before the pandemic (83.9% vs. 75.1%, p < 0.001). Periprocedural complication rates did not differ between the groups. In-hospital outcomes did not differ between analyzed periods regarding all-cause death nor cardiac death rates, 5.3% vs. 4.6% (p = 0.598) and 4.5% vs. 3.7% (p = 0.473), respectively. CONCLUSIONS: Based on the analysis of 1209 patients, a decrease in ACS patients admitted during the pandemic was recorded, but in-hospital mortality remained similar.
