However, the clinical characteristics of hospitalized patients with AF and national trends in catheter ablation at tertiary hospitals in China remain unreported. METHODS This study used the Chinese national database (Hospital Quality Monitoring System) from 2013 to 2016, which is a mandatory database that collects the front page of patients’ medical records for hospital accreditation, to describe the clinical characteristics of patients with AF as an overall cohort and as subgroups divided by catheter ablation and sex. RESULTS Of 597,919 AF patients first admitted, 57,983 patients underwent catheter ablation [56,384 cases (97.2%) of radiofrequency ablation and 1599 cases (2.8%) of cryoablation] at 746 tertiary hospitals. Nearly 10% of patients hospitalized with AF at tertiary hospitals in China underwent catheter ablation, and the percentage of patients undergoing catheter ablation was on the rise between 2013 and 2016, and the number of cases increased by 2.5 times. Compared with AF patients who did not undergo catheter ablation, those who did were younger, more frequently male, and had fewer baseline comorbidities. Although the overall CHA2DS2VASc score revealed over half of the patients were high-risk, patients who underwent catheter ablation were mostly low-risk (71.2% of males and 59.1% of females). Considering in-hospital adverse events, the overall pericardial tamponade and all-cause death incidences were 0.2% (0.6% in the ablation group) and 1.2% (0.1% in the ablation group), respectively; both of which were higher in females than males. CONCLUSIONS In this study, AF patients who underwent catheter ablation were relatively young, had a low thrombosis risk, and had few comorbidities and adverse events. Females were older and experienced more complications than males.","PeriodicalId":285674,"journal":{"name":"Journal of geriatric cardiology : JGC","volume":"424 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122296488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent study showed it could also predict myocardial infarction (MI). This study aimed to compare the Essen score’s ability to predict cerebrovascular events with compared cardiovascular events. METHODS We included patients with acute ischaemic stroke or transient ischaemic attack within seven days from the Third China National Stroke Registry. One-year cumulative event rates of combined vascular events (a composite of MI, stroke recurrence or vascular death) and cardiac events (a composite of MI, heart failure or cardiac death) was estimated using the Kaplan-Meier method. The predictive value of the Essen score was assessed with C-statistics. In multivariate Cox regression analyses, we assessed whether Essen score, etiological subtype and imaging parameters were associated with outcomes. RESULTS Of 13,012 patients were included, the cumulative one-year event rates were 10.03% for combined vascular events and 0.77% for cardiac events, respectively. Compared with those with an Essen score < 3, patients with an Essen score ≥ 3 were more likely to have a subsequent combined vascular event [hazard ratio (HR) = 1.39, 95% CI: 1.24−1.55] and cardiac events (HR = 2.30, 95% CI: 1.53−3.44). The score tended to be more predictive of the risk of MI (C-statistic = 0.63, 95% CI: 0.55−0.71) and cardiac events (C-statistic = 0.62, 95% CI: 0.56−0.67) than stroke recurrence (C-statistic = 0.55, 95% CI: 0.54−0.57) and combined vascular events (C-statistic = 0.56, 95% CI: 0.54−0.57). In multivariable analysis after adjusted Essen score, patients with multiple acute infarctions or single acute infarctions and large artery atherosclerosis subtype were independently associated with an increased risk of combined vascular events. While the cardioembolism subtype was associated with an increased risk of cardiac events. CONCLUSIONS The Essen score is potentially more suitable for risk stratification of cardiovascular events than cerebrovascular events. Moreover, future predictive tools should take brain imaging findings and cause of stroke into consideration.","PeriodicalId":285674,"journal":{"name":"Journal of geriatric cardiology : JGC","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114992315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

METHODS Data were collected from November 2014 to December 2019 as part of the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome (CCC-ACS) project. A total of 33,386 patients with AMI admitted to the index hospitals were included in this study. Two-level logistic regression was conducted to explore the factors associated with the pre-hospital delay and the associations between different pre-hospital delay and in-hospital outcomes. RESULTS Of the 33,386 patients with AMI, 70.7% of patients arrived at hospital ≥ 2 h after symptom onset. Old age, female, rural medical insurance, symptom onset at early dawn, and non-use of an ambulance predicted a prolonged pre-hospital delay (all P < 0.05). Hypertension and heart failure at admission were only significant in predicting a longer delay in patients with ST-segment elevation myocardial infarction (STEMI) (all P < 0.05). A pre-hospital delay of ≥ 2 h was associated with an increased risk of mortality [odds ratio (OR) = 1.36, 95% CI: 1.09–1.69, P = 0.006] and major adverse cardiovascular events (OR = 1.22, 95% CI: 1.02–1.47, P = 0.033) in patients with STEMI compared with a pre-hospital delay of < 2 h.

Mean length of hospital stay is about 5–6 days and with a frequent number of hospital readmission rates of 25% to 50% at 30 days and 6–12 months, respectively. Treatment options are vast and depend on certain patient characteristics, including hemodynamics, which drive the acute management. A popular modality to assess hemodynamics in acute HF is the right heart catheterization (RHC). While invasive, the use of RHC gives providers the opportunity to evaluate values that directly contribute to the management of the patient. These numbers can calculate the cardiac output as well as help establish the underlying etiology of the patient’s symptoms and guide therapy. Per Doshi, the use of right artery catheterization increased from 2010−2014 per 1000 hospitalizations compared to 2005−2010. The ESCAPE trial was a large trial that evaluated the use of RHC to guide therapy, however, results were shown to increase adverse events without affecting overall mortality and hospitalization. It was not until its use was studied in patients with cardiogenic shock (CS) in which RHC was shown to be associated with lower mortality and in-hospital cardiac arrest. Furthermore, another study compared RHC with N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurements in the prognosis of chronic HF patients. It concluded that NT-proBNP was a better predictor of all-cause mortality with the benefit of being non-invasive. The role of RHC is still not clearly defined and its necessity in guiding therapy of HF patients is controversial. It is also not wellknown which patient’s populations benefit most from it. A retrospective study was conducted at a safetynet hospital in Jacksonville, Florida, USA. Through electronic medical record review, data was collected on HF admissions, procedures, medications, and medical history between January 2020 and December 2020. Inclusion criteria involved those patients over the age of 18 years who were admitted to the cardiac care unit. A total of 176 patients fitting this criteria were reviewed and stratified by age, gender, race, comorbidities, length of stay, ejection fraction (reduced vs. preserved), etiology of cardiomyopathy (ischemic vs. nonischemic), NT-proBNP and creatinine levels.

In the present study, we identified a novel TTN mutation in a pedigree with LVNC and investigated the potential pathogenic mechanism by functional studies. METHODS The whole-genome sequencing with linkage analysis was performed in a 3-generation family affected by autosomal dominant LVNC cardiomyopathy. The clustered regularly interspaced short palindromic repeats associated protein 9 (CRISPR/Cas9) technology was used to establish novel truncating mutation in TTN in a rat cardiomyoblast H9C2 cell line in vitro, in which functional studies were carried out and characterized in comparison to its wild-type counterpart. RESULTS A novel truncating mutation TTN p. R2021X was identified as the only plausible disease-causing variant that segregated with disease among the five surviving affected individuals, with an interrogation of the entire genome excluding other potential causes. Quantitative reverse transcription-polymerase chain reaction and cellular immunofluorescence supported a haploinsufficient disease mechanism in titin truncation mutation cardiomyocytes. Further functional studies suggested mitochondrial abnormities in the presence of mutation, including decreased oxygen consumption rate, reduced adenosine triphosphate production, impaired activity of electron translation chain, and abnormal mitochondrial structure on electron microscopy. Impaired autophagy under electron microscopy accompanied with activation of the Akt-mTORC1 signaling pathway was observed in TTN p. R2021X truncation mutation cardiomyocytes. CONCLUSIONS The TTN p. R2021X mutation has a function in the cause of a highly penetrant familial LVNC. These findings expand the spectrum of titin’s roles in cardiomyopathies and provide novel insight into the molecular basis of titin-truncating variants-associated LVNC.","PeriodicalId":285674,"journal":{"name":"Journal of geriatric cardiology : JGC","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129980527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past twenty years, despite tremendous progress has been made in catheter ablation for rhythm control of AF, we still cannot establish a reliable ablative target for nonparoxysmal AF. Part of the reason is an incomplete understanding of the mechanism underlying the progressive nature of AF. In the time chain of AF, AF burden increases, and the success rate of catheter ablation decreases as AF progresses from paroxysmal AF (PAF) to persistent AF (PerAF) and long-standing persistent AF (LS-PerAF) form. Recently, with the advance in mapping technologies combined with biophysical insight, a new concept of AF maintenance has been introduced--the rotor (spiral waves). Meanwhile, the concept of complete electrical left atrial (LA) isolation has been introduced for AF with extensive atrial fibrosis. These innovative ideas enriched our armamentarium to combat different AF subtypes. This article proposes a rotor hypothesis to illustrate the mechanism underlying AF progress and discuss the application of new strategies in different AF subtypes.","PeriodicalId":285674,"journal":{"name":"Journal of geriatric cardiology : JGC","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131182277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This represented 10.9% of all PCI procedures performed in our centre during this period. We evaluated the demographic and procedural characteristics of the cohort with respect to clinical outcomes (all-cause in-hospital and 1-year mortality, in-hospital complication rates, duration of hospital admission, coronary disease angiographic complexity and major co-morbidities). The cohort was further stratified into three chronological tertiles (January 2007 to July 2012, 261 cases; August 2012 to May 2015, 261 cases; June 2015 to December 2016, 260 cases) to assess for differences over time. Predictors of mortality were identified through a multivariate regression analysis. RESULTS The number of octogenarians undergoing PCI increased nearly ten-fold over the studied period. Despite this, there were no significant differences in clinical outcomes or patient characteristics, except for the increased use of trans-radial vascular access [11.9% in first tertile vs. 73.2% in third tertile (P < 0.0001)].

METHODS We retrospectively analyzed the preoperative clinical characteristics, electrocardiograms, contrast-enhanced multidetector computed tomography scans and procedural strategies of patients who underwent TAVI in our center between January 2012 and June 2017. Quantification of calcium volume was performed for each aortic cusp above (aortic valve) and below (left ventricular outflow tract, LVOT) the basal plane. Multivariate analysis was performed to evaluate risk factors for the onset of new bundle branch block (BBB), transient and permanent atrioventricular block (tAVB, pAVB). RESULTS A total of 569 patients were included in the study. Six different prostheses were implanted (Edwards Sapien XT, n = 162; Edwards Sapien 3, n = 240; Medtronic CoreValve, n = 27; Medtronic CoreValve Evolut R, n = 21; Symetis Acurate, n = 56; Symetis Acurate neo, n = 63).
