Cardiac Catheterization In Patients Research Articles

Associations among NMR-measured inflammatory and metabolic biomarkers and accelerated aging in cardiac catheterization patients.

Research into aging has grown substantially with the creation of molecular biomarkers of biological age that can be used to determine age acceleration. Concurrently, nuclear magnetic resonance (NMR) assessment of biomarkers of inflammation and metabolism provides researchers with new ways to examine intermediate risk factors for chronic disease. We used data from a cardiac catheterization cohort to examine associations between biomarkers of cardiometabolic health and accelerated aging assessed using both gene expression (Transcriptomic Age) and DNA methylation (Hannum Age, GrimAge, Horvath Age, and Phenotypic Age). Linear regression models were used to associate accelerated aging with each outcome (cardiometabolic health biomarkers) while adjusting for chronological age, sex, race, and neighborhood socioeconomic status. Our study shows a robust association between GlycA and GrimAge (5.71, 95% CI = 4.36, 7.05, P = 7.94 × 10-16), Hannum Age (1.81, 95% CI = 0.65, 2.98, P = 2.30 × 10-3), and Phenotypic Age (2.88, 95% CI = 1.91, 3.87, P = 1.21 × 10-8). We also saw inverse associations between apolipoprotein A-1 and aging biomarkers. These associations provide insight into the relationship between aging and cardiometabolic health that may be informative for vulnerable populations.

Self Management Support for Cardiac Catheterization Patients

Introduction: Cardiac catheterization is an invasive procedure to detect blockages in the coronary arteries. Risk factors can be prevented with self-management support. Self-Management-Support care and support is provided by emphasizing the importance of the patient's central role in managing their own health. Method: This research uses a descriptive design. The research sample was 30 respondents taken based on inclusion criteria using accidental sampling technique. The measuring instrument used is a questionnaire sheet. The analysis used is univariate analysis which aims to describe the frequency distribution to find out the description of Self Management and Support in Cardiac Catheterization Patients. Results: The assessment results for all respondents are in the medium category, namely with a total of 20 respondents (66.7%), Adsive is in the good category, namely with the number 15 respondents (50%), Agree in the good category, namely with a total of 25 respondents (83.3%), Assist in the medium category, namely with a total of 23 respondents (76.7%), and Arrange in the medium category, namely with a total of 15 respondents (50%) . This research suggests that health workers continue to provide self-management support to cardiac catheterization patients to improve patient health.

Factors influencing the indication of coronary angiography in patients presenting with chest pain unspecified: an analysis of two decades (1994-2014).

Guidelines for cardiac catheterization in patients with non-specific chest pain (NSCP) provide significant room for provider discretion, which has resulted in variability in the utilization of invasive coronary angiograms (CAs) and a high rate of normal angiograms. The overutilization of CAs in patients with NSCP and discharged without a diagnosis of coronary artery disease is an important issue in medical care quality. As a result, we sought to identify patient demographic, socioeconomic, and geographic factors that influenced the performance of a CA in patients with NSCP who were discharged without a diagnosis of coronary artery disease. We intended to establish reference data points for gauging the success of new initiatives for the evaluation of this patient population. In this 20-year retrospective cohort study (1994-2014), we examined 107 796 patients with NSCP from the Myocardial Infarction Data Acquisition System, a large statewide validated database that contains discharge data for all patients with cardiovascular disease admitted to every non-federal hospital in NJ. Patients were partitioned into two groups: those offered a CA (CA group; n = 12 541) and those that were not (No-CA group; n = 95 255). Geographic, demographic, and socioeconomic variables were compared between the two groups using multivariable logistic regression, which determined the predictive value of each categorical variable on the odds of receiving a CA. Whites were more likely than Blacks and other racial counterparts (19.7% vs. 5.6% and 16.5%, respectively; P < .001) to receive a CA. Geographically, patients who received a CA were more likely admitted to a large hospital compared to small- or medium-sized ones (12.5% vs. 8.9% and 9.7%, respectively; P < .05), a primary teaching institution rather than a teaching affiliate or community center (16.1 % vs. 14.3% and 9.1%, respectively; P < .001), and at a non-rural facility compared to a rural one (12.1% vs. 6.5%; P < .001). Lastly from a socioeconomic standpoint, patients with commercial insurance more often received a CA compared to those having Medicare or Medicaid/self-pay (13.7% vs. 9.5% and 6.0%, respectively; P < .001). The utilization of CA in patients with NSCP discharged without a diagnosis of coronary artery disease in NJ during the study period may be explained by differences in geographic, demographic, and socioeconomic factors. Patients with NSCP should be well scrutinized for CA eligibility, and reliable strategies are needed to reduce discretionary medical decisions and improve quality of care.

Hematological and Cytogenetic Effects of X-rays in Cardiac Unit Workers and Catheterization Patients.

Introduction X-rays are widely used in medicine for diagnosis and treatment. Such beneficial uses may cause potentially hazardous situations for patients andworkers in the cardiac catheterization laboratory. The present study aims to estimate the radiation dose scattered in different parts of the catheterization units and doses absorbed by workers in thisunit, and patients who underwent cardiac catheterization procedures to evaluate all changes in hematological parameters and damaged cells (the cells that contain a number of chromosomal aberrations) after exposure to radiation at Azadi Teaching Hospital in the Duhok City of Iraq. Methodology Thestudy was conducted in one year and involved 19 male workers chronically exposed to X-ray machines in the cardiac catheterization laboratory, and 45 patients, 20 males and 25 females, who have been exposed to lower doses of X-ray during the cardiac catheterization process. There were 32 healthy individuals, 19 males and 13 females, as a control. Scattered radiation was calculated using an area monitoring detector.Optically Stimulated Luminescence (OSL) dosimeter andFlat Panel Detector (FPD)were used to calculate absorbed doses by workers and patients, respectively. Twelve hematological parameters before and after radiation were examined between study groups; the cytogenetic effects, damagedcells, and chromosomal aberrations of the white blood cells of workers, patientsin the catheterization unit, and individuals of the control group were analyzed. Results The results showed that the scattered X-rays in the catheterization unit after one year of continuous detection did not change significantly compared to the data before the start of the trial. The results of all blood parameters looked to be significantly different (p<0.05) compared to the controls but within the normal range.There is no significant difference (p>0.05) in corpuscular hemoglobin, white blood cells, red distribution width, and neutrophilvalues for workers after one year of exposure as compared with the control. Also, there was no significant difference (p>0.05) in white blood cells, neutrophils, and monocyte values for patients after the operation. The current study showed the damaged cells in workerswere significantlydifferent compared to the control. At the same time, the differences were non-significant for all workers (p=0.0962) after one year of exposure.The differences in damaged cells in patients were highly significant after the operation (p=0.0003). The present study demonstrated that the inductions of dicentrics, acentric, chromosome break, and ring chromosomes in human lymphocytes were intimately related to the irradiation dose. Conclusions The presentstudy found that the scattered X-rays in the catheterization unit after the end of the experiment did not change significantly. The current study also revealed that the exposure to X-rays had no significant effects on the blood indicators of workers and patients in the catheterization unit, whereas the damaged cells in patients did not change significantly compared with the control group at the beginning of the experiment.In patients, these cells were increased after the operation but were present at a high level in the workers, as compared with controls.The damaged cells in workers remained constant from the beginning of the experiment till the end.Finally, patients had increased damaged cells after the end of the trial period compared to workers.

Multimodality 3D image fusion with live fluoroscopy reduces radiation dose during catheterization of congenital heart defects.

Imaging fusion technology is promising as it is radiation and contrast sparing. Herein, we compare conventional biplane angiography to multimodality image fusion with live fluoroscopy using two-dimensional (2D)-three-dimensional (3D) registration (MMIF2D-3D) and assess MMIF2D-3D impact on radiation exposure and contrast volume during cardiac catheterization of patients with congenital heart disease (CHD). We matched institutional MMIF2D-3D procedures and controls according to patient characteristics (body mass index, age, and gender) and the seven procedure-type subgroups. Then, we matched the number of tests and controls per subgroup using chronological ordering or propensity score matching. Subsequently, we combined the matched subgroups into larger subgroups of similar procedure type, keeping subgroups with at least 10 test and 10 control cases. Air kerma (AK) and dose area product (DAP) were normalized by body weight (BW), product of body weight and fluoroscopy time (BW × FT), or product of body weight and number of frames (BW × FR), and stratified by acquisition plane and irradiation event type (fluoroscopy or acquisition). Three senior interventionists evaluated the relevance of MMIF2D-3D (5-point Likert scale). The Overall group consisted of 54 MMIF2D-3D cases. The combined and matched subgroups were pulmonary artery stenting (StentPUL), aorta angioplasty (PlastyAO), pulmonary artery angioplasty (PlastyPUL), or a combination of the latter two (Plasty). The FT of the lateral plane reduced significantly by 69.6% for the Overall MMIF2D-3D population. AKBW and DAPBW decreased, respectively, by 43.9% and 39.3% (Overall group), 49.3% and 54.9% (PlastyAO), and 36.7% and 44.4% for the Plasty subgroup. All the aforementioned reductions were statistically significant except for DAPBW in the Overall and Plasty (sub)groups. The decrease of AKBW and DAPBW in the StentPUL and PlastyPUL subgroups was not statistically significant. The decrease in the median values of the weight-normalized contrast volume (CMCBW) in all five subgroups was not significant. Cardiologists considered MMIF2D-3D very useful with a median score of 4. In our institution, MMIF2D-3D overall enabled significant AKBW reduction during the catheterization of CHD patients and was mainly driven by reduced FT in the lateral plane. We observed significant AKBW reduction in the Plasty and PlastyAO subgroups and DAPBW reduction in the PlastyAO subgroup. However, the decrease in CMCBW was not significant.

Combined Cardiac Damage Staging by Echocardiography and Cardiac Catheterization in Patients With Clinically Significant Aortic Stenosis

BackgroundCardiac damage (CD) staging enhances risk stratification in patients with clinically significant aortic stenosis (AS). We aimed to assess the prognostic value and reclassification rate of right heart catheterization (RHC) compared with transthoracic echocardiography (TTE) in characterising CD staging at 3-year follow-up in patients with clinically significant AS, to identify patients that would benefit from RHC for prognostic stratification, and to test the prognostic value of combined CD staging. MethodsAn observational cohort study of 432 AS patients undergoing TTE and RHC were divided into moderate or asymptomatic severe (m/asAS) and symptomatic severe (ssAS) AS. Kaplan-Meier curves were used to compare survival. The accuracy in prognostic stratification was tested by area under the receiver operating characteristic curve analysis and Delong test. ResultsIn both cohorts, TTE- and RHC-derived staging systems had prognostic value, although the agreement between them appeared moderate. A higher proportion of patients were assigned to stage 2 by TTE than by RHC. Patients in TTE-derived stage 2 had a high reclassification rate, with 40%-50% presenting with right chamber involvement (stages 3-4) according to RHC. Discordant cases were significantly older, with higher prevalence of atrial fibrillation, markedly elevated N-terminal pro–B-type natriuretic peptide, and higher indexed left atrial volume, E/e′, and systolic pulmonary artery pressure vs concordant cases (P < 0.05). The combined CD staging, integrating TTE and RHC, was more accurate in predicting mortality than the TTE-derived system (P < 0.05). ConclusionsIn patients with m/asAS and ssAS, the combined CD staging, derived from TTE and RHC, was more accurate in predicting mortality than TTE alone. In a subset of AS patients, the integration of RHC may significantly improve prognostic stratification.

Cardiopulmonary Test As A Component in the Diagnostic Algorithm for Heart Failure with Preserved Left Ventricular Ejection Fraction in Patients with Atrial Fibrillation

Background: Patients with heart failure with preserved ejection fraction account for more than half of all hospitalizations because of heart failure. On the other hand, atrial fibrillation and heart failure are quite often diagnosed together and one disease influences the development of the other. Timely and accurate diagnosis of heart failure with preserved ejection fraction is the basis for effective treatment of this category of patients. In 2019, the HFA-PEFF algorithm of diagnosis heart failure with preserved ejection fraction (including patients with atrial fibrillation) was proposed. However, the algorithm implies cardiac catheterization in patients at intermediate risk, which involves certain difficulties and cannot be used in routine practice. As an alternative to cardiac catheterization in the diagnosis of heart failure with preserved ejection fraction, we proposed a noninvasive diagnostic method cardiopulmonary test. However, the value of cardiopulmonary test technique has not been conclusively studied, especially in patients with a combination of chronic heart failure and atrial fibrillation. Aim: The aim of the study was to evaluate the role of the cardiopulmonary test in the diagnosis of heart failure with preserved ejection fraction in patients with atrial fibrillation. Methods: 138 patients with atrial fibrillation were included in our study. Using HFA-PEFF algorithm (algorithm for diagnosis of heart failure with preserved left ventricular ejection fraction) all patients were initially divided into 3 groups: low probability of heart failure 23 patients, intermediate probability 96 and high probability 19 patients. The stress-test allowed to precisely assess of patients at intermediate risk and finally form the groups: Group 1 without heart failure, 85 patients (61.6%); Group 2 patients with heart failure and preserved ejection fraction, 53 patients (38.4%). The next diagnostic stage was cardiopulmonary test. Results: During cardiopulmonary test, the anaerobic exercise threshold was 6.8 and 4.85 METs for the first and second groups, respectively (p 0.001), reflecting lower exercise tolerance in the second group of patients. Analysis of variance (ANOVA) demonstrated a statistically significant increase in pro-BNP levels with a decrease in peak VO2 (p 0.001). Also, analysis of variance demonstrated a significant statistical difference with respect to systolic pulmonary artery pressure in the subgroups with severely, moderately reduced oxygen consumption and in the group with normal peak VO2 (p=0.01). ROC analysis determined a peak VO2 of 20 ml/kg/min, above which the HFA-PEFF algorithm was unlikely to detect heart failure (AUC 0.73; confidence interval 0.650.82; p=0.043; sensitivity 85%; specificity 51%). Conclusion: The cardiopulmonary test is a reliable instrumental non-invasive method in the diagnosis of heart failure with preserved ejection fraction.

Delaying Cardiac Catheterization in Favor of Endoscopy in Non-ST Elevation Myocardial Infarction Patients Is Associated with Worse Outcomes: A Nationwide Analysis.

Non-variceal upper gastrointestinal bleeding (NVUGIB) in non-ST-elevation myocardial infarction (NSTEMI) is associated with substantial morbidity and mortality. We evaluated inpatient outcomes of esophagogastroduodenoscopy (EGD) before cardiac catheterization in patients with NSTEMI and NVUGIB. We utilized the National Readmission Database (2016-2019) to identify all index hospitalizations with a primary diagnosis of NSTEMI and a secondary diagnosis of NVUGIB that underwent EGD before cardiac catheterization (cases). A matched comparison cohort of similar hospitalizations that undergo EGD after cardiac catheterization were identified (controls) after 1:1 propensity score matching for age, gender, cardiac comorbidities, causes, and severity of bleeding. A total of 796 cases were matched with 796 controls. There was a higher median length of hospital stay (8 vs. 5days, P = 0.01) and median hospital charges ($111,218 vs. $99,115, P = 0.002) for cases compared to controls. There was a higher all-cause inpatient mortality in cases compared to controls (5.5% vs. 3.9%, P = 0.26). Furthermore, there was a higher proportion of patients with ICU admission (7% vs. 3%, P < 0.001), septic shock (7.1% vs. 5.8%, P = 0.41), atrial fibrillation (27.1% vs. 19.8%, P < 0.001) and acute kidney injury (42.8% vs. 29.1%, P < 0.001) for cases compared to controls. Delaying cardiac catheterization in favor of EGD is associated with increased hospital stay, costs, and cardiac complications. Further studies are warranted to establish our findings.

Is There Still a Role for Invasive Assessment of Aortic Gradient?

Advances in technology and imaging have expanded the range of tools for diagnosing aortic stenosis (AS). The accurate assessment of aortic valve area and mean pressure gradient is crucial to determine which patients are appropriate candidates for aortic valve replacement. Nowadays, these values can be obtained noninvasively or invasively, with similar results. Contrariwise, in the past, cardiac catheterization played a major role in the evaluation of AS severity. In this review, we will discuss the historical role of the invasive assessment of AS. Moreover, we will specifically focus on tips and tricks for properly performing cardiac catheterization in patients with AS. We will also elucidate the role of invasive methods in current clinical practice and their additional value to the information provided through non-invasive techniques.

Nurses’ Patient Care After Cardiac Catheterization in Al-Daman Hospital

This study aimed to assess the level of knowledge of nurses about the safety of patients after performing a cardiac catheterization process. Merowe Medical City) from August 2021 to March 2022. The study included 35 randomly selected nurses. 13-question questionnaire was designed and the data was analyzed using statistical analysis (SPSS) and presented in graphic forms. The study showed that most of the nurses (45%) have good knowledge regarding cardiac catheterization, and (8%) have poor knowledge about complications and (11%) of the nurses has poor knowledge of the time required for the patient to remain in bed after the operation. (83%) have knowledge of the time required to remove the cardiac catheterization. The study recommended conducting workshops inside the hospital on the care of cardiac catheterization patients after the operation, and the hospital administration should hold continuous training courses so that the nurses can deal with the cardiac catheterization patient after the operation and provide the best health care.

Meta-Analysis of Prophylactic Renal Replacement Therapy after Cardiac Catheterization in Patients with Chronic Kidney Disease.

The benefits of prophylactic renal replacement therapy after cardiac catheterization in patients with chronic kidney disease remain unclear. The aim of this study is to confirm the benefit of prophylactic renal replacement therapy after cardiac catheterization. We systematically searched for studies published from inception to December 2022 examining the benefits of prophylactic renal replacement therapy after cardiac catheterization in MEDLINE and EMBASE. Data analysis was performed according to the PRISMA statement using the Mantel-Haenszel method. Five studies met the inclusion criteria, which comprised of 532 chronic kidney disease patients who underwent coronary angiography (268 had prophylactic renal replacement therapy and 264 did not have prophylactic renal replacement therapy). The pooled analysis revealed a non-significant decreased risk of 1-year mortality in chronic kidney disease patients who underwent coronary angiography and prophylactic renal replacement therapy compared to those who did not have prophylactic renal replacement therapy (RR = 0.59; P =.18; CI: 0.28-1.2795, I2 = 60.4%). The risk of hemodialysis during hospitalization and renal replacement therapy requirement in 1 year in chronic kidney disease patients who underwent coronary angiography and prophylactic renal replacement therapy were lower than in those who did not have prophylactic renal replacement therapy (RR = 0.13; P =.001; CI: 0.04-0.43, I2 = 9.1% and RR = 0.29; P =.015; CI: 0.11-0.78, I2 = 49.9%, respectively). The sensitivity analysis demonstrated that the overall findings remained consistent and did not significantly alter. Prophylactic renal replacement therapy did not seem to lower 1-year mortality among chronic kidney disease patients who underwent coronary angiography. However, prophylactic renal replacement therapy appeared to reduce the risk of hemodialysis during hospitalization and renal replacement therapy requirement in 1 year.

Coronary Angiography in Patients With Out-of-Hospital Cardiac Arrest Without ST-Segment Elevation on Electrocardiograms: A Comprehensive Review

<h2>Abstract</h2> Out-of-hospital cardiac arrest (OHCA) is among the most common causes of death in the United States. Early coronary angiography (CAG) and percutaneous coronary intervention (PCI) have been associated with improved long-term outcomes in patients with ST-segment elevation (STE) on prearrest or postarrest electrocardiograms. However, data on the utility of catheterization and PCI for improving outcomes after OHCA in patients without STE on electrocardiograms are heterogeneous, with variable results. Although older data have suggested that there is a benefit, recent randomized controlled trials have demonstrated that performing early CAG in patients with OHCA without STE on electrocardiograms may not improve outcomes. In recognition that neurologic devastation and multiorgan failure are common in these patients, physicians face the challenge of selecting appropriate patients for cardiac catheterization and PCI. This review aims to summarize the current data on this topic, with the goal to guide decision making regarding the timing and appropriateness of CAG in patients with OHCA without STE on electrocardiograms, utilizing an evidence-based approach to streamline the patient selection process.

A Risk Prediction Model of Serious Adverse Events After Cardiac Catheterization for Chinese Adults Patients with Moderate and Severe Congenital Heart Disease

Background: There are almost 2 million adult patients with congenital heart disease in China, and the number of moderate and severe patients is increasing. However, few studies have investigated the risk of serious adverse events (SAE) after catheterization among them. The aim of this study was to identify risk factors for SAE related to cardiac catheterization and to provide the risk scoring model for predicting SAE. Methods: A total of 690 patients with moderate and severe adult patients with congenital heart disease (ACHD) who underwent cardiac catheterization in Wuhan Asian Heart Hospital Affiliated to Wuhan University of Science and Technology from January 2018 to January 2022 were retrospectively collected and subsequently divided into a modeling group and a verification group. A univariate analysis was performed on the identified SAE risk factors, and then significant factors were included in the multivariate logistic regression model to screen for independent predictors of SAE. The receiver operating characteristic curve (ROC) and the Hosmer-Lemeshow test were used to evaluate the discrimination and calibration of the model, respectively. Results: A SAE occurred in 69 (10.0%) of the 690 catheterization procedures meeting inclusion criteria. The established SAE risk calculation formula was logit(p) = –6.134 + 0.992 × pulmonary artery hypertension (yes) + 1.459 × disease severity (severe) + 2.324 × procedure type (diagnostic and interventional) + 1.436 × cTnI (≥0.028 μg/L) + 1.537 × NT-proBNP (≥126.65 pg/mL). The total score of the final risk score model based on the effect size of each predictor was 0 to 7, involving pulmonary artery hypertension (1 point), disease severity (1 point), procedure type (2 points), cTnI (1 point) and NT-proBNP (2 points), and the score greater than 3 means high risk. The C-statistic of the area under the ROC curve was 0.840 and 0.911 for the derivation and validation cohorts, respectively. According to the Hosmer-Lemeshow test, the p values in the modeling group and the verification group were 0.064 and 0.868, respectively. Conclusions: The risk prediction model developed in this study has high discrimination and calibration, which can provide reference for clinical prediction and evaluation of SAE risk after cardiac catheterization in patients with moderate and severe ACHD.

905 EVALUATION OF PULMONARY HYPERTENSION BETWEEN ECHOCARDIOGRAPHIC ESTIMATION AND CARDIAC CATHETERIZATION IN PATIENTS UNDERGOING TRICLIP IMPLANTATION: PRELIMINARY DATA

Abstract Background echocardiography is a helpful tool in patients with suspected pulmonary hypertension (PH). Data derived from echocardiographic examination allow to assign a level of probability of PH by using multiple parameters. Nevertheless, the gold standard for the diagnosis of PH remains the right heart catheterization. The evaluation of PH is important in patients undergoing transcatheter tricuspid valve repair, in fact, many trials excluded those with “severe” pulmonary hypertension. Aim the aim of this study was to examine, in the evaluation of PH, the parameters derived from echocardiographic estimation and cardiac catheterization in patients undergoing TriClip implantation. Methods a retrospective analysis of 4 patients underwent to TriClip implantation in our department was performed. Echocardiography and right heart catheterization data were collected. In the assessment of pulmonary hypertension, the analyzed echocardiographic parameters were: enlarged right ventricle in parasternal long-axis view (&amp;gt;30 mm), flattened interventricular septum leading to “D-shaped LV”, dilated inferior vena cava (&amp;gt;21 mm) with diminished inspiratory collapsibility (&amp;lt;50%), RVOT acceleration time of pulmonary ejection &amp;lt;105 msec, reduced right ventricular fractional area change (&amp;lt;35%), decreased tricuspid annular plane systolic excursion (TAPSE &amp;lt;18mm), TAPSE/sPAP ratio &amp;lt;0.55 mm/mmHg, enlarged right atrial area (&amp;gt;18 cm2), increased systolic peak tricuspid regurgitation velocity (peak TRV&amp;gt;2.8 m/s), estimated systolic pulmonary artery pressure (sPAP). Echocardiographic probability of pulmonary hypertension was defined as high: peak TRV &amp;gt;3.4 m/s or a peak TRV between 2.9-3.4 m/s and the presence of other echo PH sign; intermediate: peak TRV between 2.9-3.4 or peak TRV ≤2.8 m/sec with other echo PH signs; low: peak TRV ≤2.8 m/sec. Pulmonary hypertension, in accordance with guidelines, was defined by a mean pulmonary arterial pressure (mPAP)&amp;gt;20 mmHg at rest. Results the echocardiographic probability of pulmonary hypertension was high in three patients: 2 patients had a peak TRV&amp;gt;3.4 m/s, one patient had peak TRV 2.95 with RVOT AT 55, flattened interventricular septum, dilated inferior vena cava with diminished inspiratory collapsibility, right atrium area &amp;gt;18cm2. In one patient the probability was intermediate (peak TRV 2.40 m/s, RA area &amp;gt;18 cm2 and TAPSE/sPAP ratio &amp;lt;0.55 mm/mmHg). Right heart catheterization confirmed the diagnosis of pulmonary hypertension in two patients with high echocardiographic probability. In the other two patients (one with high probability and one with intermediate probability) there was no PH diagnosis at right heart catheterization. Conclusion in only two out of four patients with intermediate-high probability of PH the diagnosis was confirmed by right catheterization. Therefore, invasive evaluation of pulmonary pressures should be performed in patients with severe tricuspid regurgitation undergoing Triclip implantation.

The association of accelerated epigenetic age with all-cause mortality in cardiac catheterization patients as mediated by vascular and cardiometabolic outcomes

BackgroundEpigenetic age is a DNA methylation-based biomarker of aging that is accurate across the lifespan and a range of cell types. The difference between epigenetic age and chronological age, termed age acceleration (AA), is a strong predictor of lifespan and healthspan. The predictive capabilities of AA for all-cause mortality have been evaluated in the general population; however, its utility is less well evaluated in those with chronic conditions. Additionally, the pathophysiologic pathways whereby AA predicts mortality are unclear. We hypothesized that AA predicts mortality in individuals with underlying cardiovascular disease; and the association between AA and mortality is mediated, in part, by vascular and cardiometabolic measures.MethodsWe evaluated 562 participants in an urban, three-county area of central North Carolina from the CATHGEN cohort, all of whom received a cardiac catheterization procedure. We analyzed three AA biomarkers, Horvath epigenetic age acceleration (HAA), phenotypic age acceleration (PhenoAA), and Grim age acceleration (GrimAA), by Cox regression models, to assess whether AAs were associated with all-cause mortality. We also evaluated if these associations were mediated by vascular and cardiometabolic outcomes, including left ventricular ejection fraction (LVEF), blood cholesterol concentrations, angiopoietin-2 (ANG2) protein concentration, peripheral artery disease, coronary artery disease, diabetes, and hypertension. The total effect, direct effect, indirect effect, and percentage mediated were estimated using pathway mediation tests with a regression adjustment approach.ResultsPhenoAA (HR = 1.05, P < 0.0001), GrimAA (HR = 1.10, P < 0.0001) and HAA (HR = 1.03, P = 0.01) were all associated with all-cause mortality. The association of mortality and PhenoAA was partially mediated by ANG2, a marker of vascular function (19.8%, P = 0.016), and by diabetes (8.2%, P = 0.043). The GrimAA-mortality association was mediated by ANG2 (12.3%, P = 0.014), and showed weaker evidence for mediation by LVEF (5.3%, P = 0.065).ConclusionsEpigenetic age acceleration remains strongly predictive of mortality even in individuals already burdened with cardiovascular disease. Mortality associations were mediated by ANG2, which regulates endothelial permeability and angiogenic functions, suggesting that specific vascular pathophysiology may link accelerated epigenetic aging with increased mortality risks.

Chest Radiography Should Not Be Routinely Performed Prior to Cardiac Catheterization in Patients With ST-elevation Myocardial Infarction

Acute ST-elevation myocardial infarction (STEMI) represents the most devastating form of acute coronary syndrome. Prompt reperfusion, ideally through percutaneous coronary intervention (PCI), optimizes outcomes among patients with STEMI. Delays in percutaneous coronary intervention, as measured by door-to-balloon time, are associated with a significant rise in mortality. Indeed, a recent Cochrane Review estimated that every 30-minute delay in door-to-balloon time results in a 17% relative increase in short-term mortality.

Chest Radiography Should Be Routinely Performed Prior to Cardiac Catheterization in Patients With ST-elevation Myocardial Infarction

Emphasis has been placed on minimizing the time between the diagnosis of a ST-elevation myocardial infarction (STEMI) and the initiation of appropriate intervention. This drive to shorten “door to needle” time should not, however, cause emergency physicians to forgo important testing or fall into the trap of diagnostic anchoring. A portable single-view chest radiograph can be rapidly obtained and interpreted in any emergency department (ED) and is a low-cost and low-risk test with potential diagnostic and prognostic implications.

Post-operative nursing safety practices for cardiac catheterization patients

Background: In recent years, there has been a greater emphasis on the epidemiological of mistakes and adverse outcomes rather than on procedures that decrease such incidents. aim of study is to: Assess nurses Knowledge regarding preoperative nursing safety practices for cardiac catheterization patients. Methodology: The descriptive research design was utilized for this study. and the sitting of the study was at AL Hussein teaching hospital in Al muthanna governorate. The subjects of the study consisted of all nurses (30 nurses) working at the above mentioned. The toll of the study included the safety practices in the postoperative phase cardiac catheterization. These were categorized a checklist related to the availability of the equipment and safety items provided for patients at the catheterization unit. This checklist items was checked as being either available (2) ,or (1) not available (0). As regard safety it is a three Likert scale ranged from done completely (2), done incompletely (1), to not done (0). Result: the main results of study reveal that, there was no a highly significant relation between socio-demographic characteristics and nursing safety practices for cardiac catheterization patients at preoperative phase.
