Abstract
AIMS Patients with obesity have an overall higher cardiovascular risk, at the same time obesity could be associated with a better outcome in a certain subgroup of patients, a phenomenon known as the obesity paradox. Data are scarce in candidates for cardiac resynchronization therapy (CRT). We aimed to investigate the association between body mass index (BMI) and all-cause mortality in patients eligible for CRT. METHODS Altogether 1,585 patients underwent cardiac resynchronization therapy between 2000-2020 and were categorized based on their BMI, 459 (29%) patients with normal weight (BMI < 25 kg/m2), 641 (40%) patients with overweight (BMI 25- < 30 kg/m2) and 485 (31%) with obesity (BMI ≥ 30 kg/m2). The primary endpoint was all-cause mortality, heart transplantation, and left ventricular assist device implantation. We assessed periprocedural complications and 6-month echocardiographic response. RESULTS Normal-weight patients were older compared to patients with overweight or obesity (70 years vs. 69 years vs. 68 years; P ‹0.001), respectively. Sex distribution, ischaemic aetiology, and CRT-D implantation rates were similar in the three patient groups. Diabetes mellitus (BMI < 25 kg/m2 26% vs. BMI 25- < 30 kg/m2 37% vs. BMI ≥ 30 kg/m2 48%; P ‹0.001) and hypertension (BMI < 25 kg/m2 71% vs. BMI 25- < 30 kg/m2 74% vs. BMI ≥ 30 kg/m2 82%; P ‹0.001) were more frequent in patients with overweight and obesity. During the mean follow-up time of 5.1 years, 973 (61%) reached the primary endpoint, 66% in the BMI < 25 kg/m2 group, 61% in the BMI 25- < 30 kg/m2 group and 58% in the BMI ≥ 30 kg/m2 group (log-rank P‹0.05). Patients with obesity showed mortality benefit over normal-weight patients (HR 0.78; 95%CI 0.66-0.92; P = 0.003). The obesity paradox was present in patients free from diabetes, atrial fibrillation, and ischemic events. Periprocedural complication rates did not differ in the three groups (BMI < 25 kg/m2 25% vs. BMI 25- < 30 kg/m2 28% vs. BMI ≥ 30 kg/m2 26%; P = 0.48). Left ventricular ejection fraction improved significantly in all patient groups (BMI < 25 kg/m2 median∆ $$ \Delta $$ -LVEF 7% vs. BMI 25- < 30 kg/m2 median∆ $$ \Delta $$ -LVEF 7.5% vs. BMI ≥ 30 kg/m2 median∆ $$ \Delta $$ -LVEF 6%; P < 0.0001) with a similar proportion of developing reverse remodeling (BMI < 25 kg/m2 58% vs. BMI 25- < 30 kg/m2 61% vs. BMI ≥ 30 kg/m2 57%; P = 0.48); P = 0.75). CONCLUSIONS The obesity paradox was present in our HF cohort at long-term, patients underwent CRT implantation with obesity and free of comorbidities showed mortality benefit compared to normal weight patients. Patients with obesity showed similar echocardiographic response and safety outcomes compared to normal weight patients.

[PMID: 38333407 PMCID: PMC10848632 DOI: 10.1002/joa3.12949] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 10/11/2023] [Accepted: 10/17/2023] [Indexed: 02/10/2024] Open
Abstract
Background Fluoroscopy is conventionally performed for cardiac implantable electronic device (CIED) therapy and carries radiation drawback for both patients and medical workers. Recently, zero to minimal fluoroscopy (ZMF) approach is introduced to reduce radiation exposure of fluoroscopy. This study compares the feasibility and safety of ZMF approach to fluoroscopy for CIEDs therapy in adults. Method A systematic literature search was conducted on PubMed, ScienceDirect, and Web of Science in March 2023. All observational or experimental studies comparing ZMF approach to fluoroscopy for adult CIEDs therapy were included. Reviews, case report/series, animal studies, and non-English articles were excluded. The success rate, procedural time, fluoroscopy time, radiation dose, and complications rate were compared for each approach. Results Seven articles for permanent and three articles for temporary CIEDs were included for analysis. The success rate of ZMF for permanent CIEDs was similar to fluoroscopy method (OR: 0.77, 95% CI: 0.33-4.15). The procedural time of ZMF was similar to fluoroscopy for both permanent and temporary CIEDs (standardized mean difference [SMD]: 0.10, 95% CI: -0.35 to 0.55 and SMD: -0.71, 95% CI: -1.87-0.44, respectively). However, ZMF approach markedly reduced the fluoroscopy time and radiation exposure for permanent CIEDs (SMD: -1.80, 95% CI: -2.49 to -1.12 and SMD: -1.26, 95% CI: -2.24 to -0.29). The complication rate was similar for permanent CIEDs (OR: 1.08, 95% CI: 0.41-2.84), yet lowered for temporary CIEDs (OR: 0.34, 95% CI: 0.20-0.59). Conclusion ZMF had similar success rate, procedural time, and sum complication rate for permanent CIEDs implantation with a significant reduction of fluoroscopy time and radiation exposure.

Abstract
Many unique clinical challenges accompany the diagnosis and treatment of cardiovascular disease (CVD) in people living with overweight/obesity. Similarly, physicians encounter numerous complicating factors when managing obesity among people with CVD. Diagnostic accuracy in CVD medicine can be hampered by the presence of obesity, and pharmacological treatments or cardiac procedures require careful adjustment to optimize efficacy. The obesity paradox concept remains a source of confusion within the clinical community that may cause important risk factors to go unaddressed, and body mass index is a misleading measure that cannot account for body composition (eg, lean mass). Lifestyle modifications that support weight loss require long-term commitment, but cardiac rehabilitation programs represent a potential opportunity for structured interventions, and bariatric surgery may reduce CVD risk factors in obesity and CVD. This review examines the key issues and considerations for physicians involved in the management of concurrent obesity and CVD.

JACC Clin Electrophysiol 2022; 8:88-100. [PMID: 34454890 PMCID: PMC9339254 DOI: 10.1016/j.jacep.2021.06.006] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 06/08/2021] [Accepted: 06/09/2021] [Indexed: 01/03/2023]
Abstract
OBJECTIVES This study sought to describe trends in cardiovascular implantable electronic device (CIED) insertion over the past 3 decades in Olmsted County. BACKGROUND Trends in CIED insertion in the United States have not been extensively studied. METHODS The Rochester Epidemiology Project is a medical records linkage system comprising the records of all residents of Olmsted County from 1966 to the present. CIED insertion between 1988 and 2018 was determined using International Classification of Diseases-Ninth Revision, International Classification of Diseases-10th Revision, and Current Procedural Terminology codes. Age- and sex-adjusted incidence rates, adjusted to the 2010 US White population, were calculated. Trends in incidence over time, across age groups, and between sex are estimated using Poisson regression models. RESULTS The age- and sex-adjusted incidence of device implants for the study period were as follows: overall CIED: 82.4 (95% CI: 79.2-85.6); permanent pacemaker (PPM): 62.9 (95% CI: 60.0-65.7); implantable cardioverter-defibrillator (ICD): 14.0 (95% CI: 12.6-15.3); and cardiac resynchronization therapy (CRT): 5.6 (95% CI: 4.7-6.4) per 100,000 per year. The overall incidence of CIED insertion increased between 1988 to 1993 and 2000 to 2005 and then decreased between 2000 to 2005 and 2012 to 218 (P < 0.0001). PPM and ICD insertion incidence followed these trends, whereas the incidence of CRT insertion increased between 2000 to 2005 and 2012 to 2018. CIED insertion incidence increased with age (P < 0.0001). CIED insertion incidence was greater in men (116.3 vs 57.3 per 100,000 per year in men vs women; P < 0.0001). The overall survival of CRT recipients improved (P = 0.0044). CONCLUSIONS The incidence values for PPM and ICD implants are decreasing, while the incidence of CRT implants is increasing. CIEDs are increasingly inserted in the elderly, men, and patients with higher comorbidities.

Evaluation of a new ultralow-dose radiation protocol for electrophysiological device implantation: A near-zero fluoroscopy approach for device implantation. Heart Rhythm 2019; 17:90-97. [PMID: 31494091 DOI: 10.1016/j.hrthm.2019.07.031] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2019] [Indexed: 11/25/2022]
Abstract
BACKGROUND Radiation is one of the main hazards of electrophysiological device implantation, and insertion of cardiac resynchronization therapy (CRT) devices in particular is associated with high radiation doses. OBJECTIVE The purpose of this study was to evaluate the impact of a new ultralow-dose radiation protocol on radiation doses, success rate, and safety of electrophysiological device implantations. METHODS In 2018, we established a new ultralow-dose radiation protocol (reduced pulse width, increased thickness of minimum copper filters, reduced detector entrance dose, reduced pulse rate, optimized image postprocessing settings) for de novo device implantation at our hospital. A total of 1173 patients (11% single-chamber devices, 69% dual-chamber devices, 20% CRT devices) were analyzed. Five hundred twelve patients (44%) in the ultralow-dose group were compared to 661 patients (66%) treated during 2017 with a conventional low-dose protocol. RESULTS With the ultralow-dose radiation protocol, effective doses could be reduced by 59% (median 0.25 [interquartile range: 0.11-0.63] vs median 0.10 [interquartile range: 0.03-0.28] mSv; P <.0001) per procedure without a significant change in procedure time (P = .5). This dose reduction could be achieved without decreasing procedure success (P = 1) or increasing complication rate (P = .8). Male gender, higher body mass index, increased procedure and fluoroscopy times, and use of the conventional radiation protocol were independent predictors of higher radiation doses in multivariate regression analysis. CONCLUSION By establishing a new ultralow-dose radiation protocol, we could significantly decrease radiation exposure, reaching the lowest radiation doses for electrophysiological device implantation reported to date.

Association of body mass index with cardiac resynchronization therapy intention and left ventricular lead implantation failure: insights from the NCDR implantable cardioverter-defibrillator registry. J Interv Card Electrophysiol 2019; 57:279-288. [PMID: 31004224 DOI: 10.1007/s10840-019-00550-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2019] [Accepted: 04/03/2019] [Indexed: 11/24/2022]
Abstract
BACKGROUND Cardiac resynchronization therapy with defibrillator (CRT-D) implantation involves left ventricular (LV) lead placement for biventricular pacing and is more complex than implantable cardioverter-defibrillator (ICD)-only implantation. Differences in the prescription of CRT-D versus ICD may result from clinician biases based on patient body habitus, and body habitus may be associated with LV lead implantation failure. OBJECTIVE We sought to evaluate whether patient body mass index (BMI) was associated with planned use and implantation failure of CRT-D therapy. METHODS We studied all patients enrolled in the National Cardiovascular Data Registry ICD Registry who met standard CRT-D criteria and received either an ICD or CRT-D between 2010 and 2012. BMI was categorized based on World Health Organization classification. Using hierarchical logistic regression, two multivariate models adjusted for patient demographic and clinical characteristics were fit based on the following outcome variables: (1) planned implantation with CRT-D versus ICD and (2) failed versus successful LV lead placement. RESULTS Of 337,547 patients, 41,872 met inclusion criteria for the first analysis and 35,186 met criteria for the second analysis. After multivariable adjustment, patients with extreme (BMI > 40 kg/m2) obesity were less likely to receive guideline-concordant CRT-D compared with patients with normal weight (adjusted odds ratio (AOR), 0.86; 95% confidence interval (CI), 0.75-0.99; p = 0.04). Extreme (BMI > 40 kg/m2) obesity was associated with higher odds of failed LV lead placement (AOR, 1.35; 95% CI, 1.07-1.72, p = 0.01). CONCLUSIONS Compared with normal weight patients, extremely obese (BMI > 40 kg/m2) CRT-D eligible patients were less likely to be prescribed CRT-D and were at higher odds for failed LV lead placement.

Abstract
BACKGROUND Obesity is associated with increased complications and potentially worse outcomes for various cardiac interventions. This study analyzed the success rate and complication rates associated with implantation of cardiac implantable electronic devices (CIEDs) in obese patients. HYPOTHESIS Success rates are lower and complication rates higher in obese patients. METHODS Consecutive patients undergoing CIED implantation between 2011 and 2015 in our hospital were included. Patients were categorized into obese and nonobese groups according to body mass index (BMI); cutoff was 30 kg/m2 . Patient characteristics, complication rates, procedural duration, and fluoroscopy data were compared between the 2 groups. RESULTS A total of 965 patients (mean age, 69.0 ± 12.9 years; 67% male) were included. Of these, 249 (25.8%) patients were classified obese and 716 (74.2%) nonobese. Mean BMI was 34.7 ± 4.7 kg/m2 vs 25.1 ± 3.0 kg/m2 , respectively. There was no difference in procedural success rates between the 2 groups (97.2% vs 97.1%, respectively). Major complications were significantly lower in the obese group compared with the nonobese group (11 [4.4%] vs 62 [8.7%]; P < 0.05). Procedural duration and fluoroscopy duration were not different between the 2 groups, but the total dose-area product was significantly higher in obese patients vs nonobese patients (4012 ± 5416 cGcm2 vs 2692 ± 5277 cGcm2 ; P < 0.005). CONCLUSIONS CIED implantation can be safely and effectively achieved in patients with BMI >30 kg/m2 . However, total radiation dose was significantly higher in the obese group, emphasizing that efforts should be made to reduce radiation exposure in these patients.
