[PMID: 36459732 DOI: 10.1016/j.amjcard.2022.10.038] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 09/27/2022] [Accepted: 10/17/2022] [Indexed: 11/30/2022]
Abstract
Few researchers have discussed the differences in gender between the age groups of patients who underwent transcatheter aortic valve implantation (TAVI). We searched the National Readmissions Database from 2012 to 2019 to identify adults who underwent TAVI. We studied hospital outcomes and short- to medium-term outcomes by age stratification (18 to 59, 60 to 69, 70 to 79, and 80 to 90 years) after TAVI and categorized by gender. We included 147,481 patients who underwent TAVI, and 54,802 pairs were matched using propensity score matching separately for each age group. Compared with men, women in all age groups had a similar rate of hospital death. Except the 18- to 59-year-old groups, female patients were less likely to undergo permanent pacemaker implantation and transfusion. Records of readmission at 30 days and 6 months were used as the follow-up outcome according to the presence or absence of readmission. Major adverse cardiovascular events (MACEs) were a composite of cardiovascular readmission, all-cause mortality during readmission, and stroke readmission. At the 30-day follow-up visit, there was no difference in the all-cause readmission and MACE between women and men in any group. At the 6-month follow-up visit, women in the 70- to 79-year-old and 80- to 90-year-old groups had a high risk of all-cause readmission. In conclusion, we reported that female patients have similar in-hospital death rates to male patients who underwent TAVI. During the 30-day follow-up visit, the all-cause readmission and MACE were not different in all age groups between men and women. At 6 months, women in the 70- to 79-year-old and 80- to 90-year-old groups had a higher risk of all-cause readmission.

Abstract
ObjectivesEpidemiological data on intraventricular conduction disturbances (IVCDs) are limited in the Chinese population. We aimed to investigate the prevalence and incidence of different types of IVCDs among Chinese adults.MethodsFrom June 2006 to October 2007, a total of 100,250 individuals from the Kailuan Study underwent electrocardiogram examinations. Follow-up visits were performed biennially. The prevalence and incidence of right bundle branch block (RBBB), incomplete RBBB (IRBBB), left bundle branch block (LBBB), incomplete LBBB, left anterior fascicular block (LAFB), left posterior fascicular block (LPFB) and non-specific IVCD (NIVCD) were calculated. Their association with risk factors and cardiovascular diseases was also investigated.ResultsThe prevalence and incidence of all IVCDs were 3.19 and 1.70%, respectively. RBBB, IRBBB, and LAFB were the IVCD types that had the highest prevalence and incidence. The prevalence (3.67% vs. 1.29%; P < 0.001) and incidence (1.93% vs. 0.84%; P < 0.001) of IVCDs were higher among males than among females. The prevalence and incidence of most IVCD types increased with age. IRBBB, LBBB, and LAFB were significantly associated with hypertension. LBBB and NIVCD were associated with diabetes mellitus. In addition, LBBB and LAFB were related to prior myocardial infarction.ConclusionIVCDs differ in prevalence and incidence according to sex and age group. They also show disparate associations with other cardiovascular comorbidities. These differences need to be considered in daily clinical practice.

Abstract
Aims To identify the prevalence of major and minor electrocardiographic abnormalities and their association with the main risk factors for cardiovascular disease in a population in the province of Bengo, northern Angola. Methods A cross-sectional community-based study was conducted and a representative random sample stratified by sex and age was selected. In total, 2379 black individuals were included in the final analysis. A standard 12-lead ECG were recorded from all participants, analyzed and processed by the University of Glasgow software and coding by the Minnesota code. Results 22.3% of participants had minor electrocardiographic abnormalities and 4.58% major ECG abnormalities. The most common minor ECG abnormalities were abnormal T wave inversion, minor isolated ST abnormalities and premature beats. The most common major ECG abnormalities were Left ventricular hypertrophy with major ST-T abnormalities, Ventricular conduction defects and major Q-wave abnormalities. Hypertension, diabetes mellitus, hypercholesterolemia, alcohol consumption and smoking, were significantly associated with major and minor electrocardiographic abnormalities. Conclusions In this study several participants had minor and major electrocardiographic abnormalities. Minor electrocardiographic abnormalities were more prevalent in men and major abnormalities in women. The electrocardiographic abnormalities had significant associations with the main cardiovascular risk factors.

Fascicular heart blocks and risk of adverse cardiovascular outcomes: Results from a large primary care population. Heart Rhythm 2021; 19:252-259. [PMID: 34673253 DOI: 10.1016/j.hrthm.2021.09.041] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 09/25/2021] [Accepted: 09/28/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND Fascicular heart blocks can progress to complete heart blocks, but this risk has not been evaluated in a large general population. OBJECTIVE The purpose of this study was to investigate the association between various types of fascicular blocks diagnosed by electrocardiographic (ECG) readings and the risk of incident higher degree atrioventricular block (AVB), syncope, pacemaker implantation, and death. METHODS We studied primary care patients referred for ECG recording between 2001 and 2015. Cox regression models were used to estimate hazard ratios (HRs) as well as absolute risks of cardiovascular outcomes. RESULTS Of 358,958 primary care patients (median age 54 years; 55% women), 13,636 (3.8%) had any type of fascicular block. Patients were followed up to 15.9 years. We found increasing HRs of incident syncope, pacemaker implantation, and third-degree AVB with increasing complexity of fascicular block. Compared with no block, isolated left anterior fascicular block (LAFB) was associated with 0%-2% increased 10-year risk of developing third-degree AVB (HR 1.6; 95% confidence interval [CI] 1.25-2.05), whereas right bundle branch block combined with LAFB and first-degree AVB was associated with up to 23% increased 10-year risk (HR 11.0; 95% CI 7.7-15.7), depending on age and sex group. Except for left posterior fascicular block (HR 2.09; 95% CI 1.87-2.32), we did not find any relevant associations between fascicular block and death. CONCLUSION We found that higher degrees of fascicular blocks were associated with increasing risk of syncope, pacemaker implantation, and complete heart block, but the association with death was negligible.

Abstract
BACKGROUND We performed a nationwide population-based cohort study to investigate sex differences in rate of permanent pacemaker implantation after surgical aortic valve replacement (AVR). METHODS This study included all adult patients who underwent primary AVR in Sweden between 2005 and 2018. Study data were obtained from the SWEDEHEART register and other Swedish national health-data registers. The rate of permanent pacemaker implantation within 30 days of surgery was compared between men and women. We estimated propensity scores that was used for inverse probability of treatment weighting to account for sex differences in patient characteristics. RESULTS A total of 18131 patients were included, 11657(64%) men and 6474(36%) women. The rate of permanent pacemaker implantation did not differ between women and men (3.8% (95% CI, 3.2%-4.3%) vs. 3.7% (95%CI, 3.3%-4.1%);p=0.831). In patients <60 years of age, the rate of permanent pacemaker implantation was significantly higher in women (6.2% (95%CI, 4.3%-8.0%) vs. 3.6% (95%CI, 2.8%-4.4%);p=0.006). The odds of pacemaker implantation in patients <60 years of age was significantly higher in women (odds ratio, 1.76; 95%CI, 1.17-2.63;p=0.006). In patients aged 60-79 years and ≥80 years, the rate of pacemaker implantation did not differ between men and women. CONCLUSIONS The rate of permanent pacemaker implantation after surgical AVR in patients <60 years of age was higher in women than men. The susceptibility to conduction disturbances requiring permanent pacemaker implantation in women below 60 years warrants further investigation and should be recognized as transcatheter aortic valve replacement expands into younger patients.

Abstract
BACKGROUND Intraventricular conduction disturbances are associated with an increased risk of adverse cardiovascular outcomes. However, data about factors associated with intraventricular conduction disturbances are sparse. We aimed to identify the clinical factors associated with intraventricular conduction disturbances in the general population. METHODS Cross-sectional study in a sample of 3704 participants (age range 45-86 years, 55.2% women). Intraventricular conduction disturbances were defined as QRS > 110 ms on electrocardiograms, and classified into right bundle branch block (RBBB), left bundle branch block (LBBB), left anterior fascicular block (LAFB) and non-specific intraventricular conduction disturbances (NIVCD). RESULTS The number of participants, the resulting prevalence (square brackets) and 95% CI (round brackets) of intraventricular conduction disturbances and subtypes (RBBB, LBBB, LAFB and NIVCD) were 187 [5.1% (4.4-5.8%)], 103 [2.9%, (2.3-3.4%)], 29 [0.8% (0.6-1.1%)], 31 (0.9% [0.6-1.2%]), and 47 [1.3% (0.9-1.7)], respectively. Multivariable logistic regression identified male sex [odds ratio and (95% CI): 2.55 (1.34-4.86)] and increasing age (p-value for trend <0.001) as being associated with RBBB; hypertension [3.08 (1.20-7.91)] and elevated NT-proBNP [3.26 (1.43-7.41)] as being associated with LBBB; elevated NT-proBNP [3.14 (1.32-7.46)] as being associated with LFAB; and male sex [5.97 (1.91-18.7)] and increased height [1.31 (1.06-1.63)] as being associated with NIVCD. CONCLUSION In a sample of the Swiss middle-aged population, the clinical factors associated with intraventricular conduction disturbances differed according to the intraventricular conduction disturbances subtype: male sex and ageing for RBBB; hypertension and elevated NT-proBNP for LBBB; elevated NT-proBNP for LAFB; and male sex and increased height for NIVCD.

Abstract
This study aims to assess the prevalence of electrocardiographic abnormalities based on the Minnesota code from a large sample of 1.01 m adult Brazilian primary care patients and to evaluate its association with age, sex, and cardiovascular risk factors. A large electrocardiogram (ECG) database of such patients aged ≥18 years (mean age 52 ± 17 years-old with 60.2% female). was analyzed and the results were stratified by sex and age. The prevalence of abnormalities was more common in men and the elderly population. Major electrocardiographic abnormalities were observed in 20.2% of adults and 43.1% of elderly patients, and minor abnormalities were found in 46.0% 39.4%, respectively. For adult patients, the number and percentage of major abnormalities rise depending on the number of cardiovascular risk factors. For elderly patients, the correlation between these variables is not clear, and the percentage of major abnormalities remains stable independently of the number of risk factors.

Abstract
We conducted a review of the literature regarding epidemiology, clinical, electrocardiographic and vectorcardiographic aspects, classification, and differential diagnosis of left posterior fascicular block. Isolated left posterior fascicular block (LPFB) is an extremely rare finding both in the general population and in specific patient groups. In isolated LPFB 20% of the vectorcardiographic (VCG) QRS loop is located in the right inferior quadrant and when associated with right bundle branch block (RBBB) ≥40%. The diagnosis of LPFB should always consider the clinical aspects, because a definite diagnosis cannot be made in the presence of right ventricular hypertrophy (RVH) (chronic obstructive pulmonary disease (COPD)/emphysema), extensive lateral myocardial infarction (MI) or extremely vertical heart. Intermittent LPFBs are never complete blocks (transient or second degree LPFB) and even in the permanent ones, one cannot be sure that they are complete. When LPFB is associated with RBBB and acute inferior MI, PR interval prolongation is very frequent.

Abstract
BACKGROUND Recommendations for the interpretation of electrocardiogram have been published in 2009. The aim of this study was to define the prevalence of intraventricular conduction disturbances (ICoDs) in a large population, using these recommendations. METHODS From 01/31/1996 to 09/22/2010, an electrocardiogram was performed at each visit for all aircrew members examined for fitness assessment in an aeromedical center. The prevalence of left bundle branch block (LBBB), right bundle branch block (RBBB), incomplete LBBB, incomplete RBBB, nonspecific intraventricular disturbance (NIVCD), left anterior fascicular block (LAFB), and left posterior fascicular block (LPFB) was measured and compared by age and gender. RESULTS The global prevalence of ICoD was 3.09% in our population of 69,186 patients. The most frequent types of ventricular blocks were IRBBB (1.25%) and LAFB (1.10%), whereas RBBB (0.46%), LBBB (0.08%), ILBBB (0.03%), NIVCD (0.05%), and LPFB (0.13%) were rare findings. ICoDs are more frequent for males and older age groups (P < 0.001). DISCUSSION Our results are comparable to studies concerning low cardiovascular risks populations. The association between ICoD and cardiovascular diseases needs to be studied in this population.
