Abstract
As the population continues to grow, and life expectancy has increased, aortic stenosis (AS) has become the most common valvular disease requiring surgical treatment. The evolution of valve replacement therapies has progressed significantly since 1960. In the last 20 years, transcatheter aortic valve implantation (TAVI) has been a game changer, and has potential to become the standard of care. Despite uncertain prognosis benefits, balloon aortic valvuloplasty (BAV) can be useful in a broad range of patients with AS, as well as being a bridging therapy to valve replacement, or as a destination therapy, besides its role in TAVI procedures. This review describes the contemporary role of BAV in AS treatment, and focuses on technical improvements that reframe BAV as an effective tool in a variety of clinical scenarios. One of these improvements is transradial BAV, either with the conventional approach of BAV or applying the bilateral technique with two balloons.

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.

Abstract
Efforts to reduce and optimize the radiation exposure during coronary angiography and intervention have pointed at patients' body size as a major determinant of irradiation for the patients and operators. We aimed at comparing body weight and body mass index (BMI) among consecutive patients undergoing angiographic procedures (coronary angiography and/or interventions) in a single center. Patients were divided in normal weight (NW, BMI <25 Kg/m2) and overweight (OW, BMI ≥25 Kg/m2). Patients' dose exposure was evaluated as dose area product (DAP), time of exposure (fluoroscopy duration), and relative DAP (DAP/minutes of exposure). We included 748 patients, 61.6% undergoing percutaneous coronary interventions and 56.8% classified as OW. OW patients were more often men (P < .001), with history of hypertension (P < .001) and diabetes (P = .001). Mean DAP and relative DAP were significantly higher among OW compared with NW patients (P < .001). DAP and relative DAP were directly related with body weight (both r = .22, P < .001); a similar linear association was also described for BMI (r = .18, P < .001 and r = .19, P < .001, respectively). At multivariate analysis, however, body weight, but not BMI, independently predicted the DAP. Therefore, body weight should be considered as the preferred indicator of body size in the setting and optimization of radiation exposure during coronary diagnostic and intervention procedures.

Abstract
OBJECTIVE This study was performed to evaluate physician radiation doses with the use of a suspended lead suit. BACKGROUND Interventional cardiologists face substantial occupational risks from chronic radiation exposure and wearing heavy lead aprons. METHODS Head-level physician radiation doses, collected using real-time dosimeters during consecutive coronary angiography procedures, were compared with the use of a suspended lead suit versus conventional lead aprons. Multiple linear regression analyses were completed using physician radiation doses as the response and testing patient variables (body mass index, age, sex), procedural variables (right heart catheterization, fractional flow reserve, percutaneous coronary intervention, radial access), and shielding variables (radiation-absorbing pad, accessory lead shield, suspended lead suit) as the predictors. RESULTS Among 1054 coronary angiography procedures, 691 (65.6%) were performed with a suspended lead suit and 363 (34.4%) with lead aprons. There was no significant difference in dose area product between groups (61.7 [41.0, 94.9] mGy·cm2 vs. 64.6 [42.9, 96.9] mGy·cm2 , p = 0.20). Median head-level physician radiation doses were 10.2 [3.2, 35.5] μSv with lead aprons and 0.2 [0.1, 0.9] μSv with a suspended lead suit (p < 0.001), representing a 98.0% reduced dose with suspended lead. In the fully adjusted regression model, the use of a suspended lead suit was independently associated with a 93.8% reduction (95% confidence interval: -95.0, -92.3; p < 0.001) in physician radiation dose. CONCLUSION Compared to conventional lead aprons, the use of a suspended lead suit during coronary angiography was associated with marked reductions in head-level physician radiation doses.

Abstract
The global obesity epidemic is well established, with increases in obesity prevalence for most countries since the 1980s. Obesity contributes directly to incident cardiovascular risk factors, including dyslipidemia, type 2 diabetes, hypertension, and sleep disorders. Obesity also leads to the development of cardiovascular disease and cardiovascular disease mortality independently of other cardiovascular risk factors. More recent data highlight abdominal obesity, as determined by waist circumference, as a cardiovascular disease risk marker that is independent of body mass index. There have also been significant advances in imaging modalities for characterizing body composition, including visceral adiposity. Studies that quantify fat depots, including ectopic fat, support excess visceral adiposity as an independent indicator of poor cardiovascular outcomes. Lifestyle modification and subsequent weight loss improve both metabolic syndrome and associated systemic inflammation and endothelial dysfunction. However, clinical trials of medical weight loss have not demonstrated a reduction in coronary artery disease rates. In contrast, prospective studies comparing patients undergoing bariatric surgery with nonsurgical patients with obesity have shown reduced coronary artery disease risk with surgery. In this statement, we summarize the impact of obesity on the diagnosis, clinical management, and outcomes of atherosclerotic cardiovascular disease, heart failure, and arrhythmias, especially sudden cardiac death and atrial fibrillation. In particular, we examine the influence of obesity on noninvasive and invasive diagnostic procedures for coronary artery disease. Moreover, we review the impact of obesity on cardiac function and outcomes related to heart failure with reduced and preserved ejection fraction. Finally, we describe the effects of lifestyle and surgical weight loss interventions on outcomes related to coronary artery disease, heart failure, and atrial fibrillation.

Abstract
BACKGROUND Patient BMI is associated with radiation doses received by interventional cardiologists, yet the association between patient BMI and nurse radiation doses is unknown. This study evaluated the association between patient body mass index (BMI) and nurse radiation doses during coronary angiography. METHODS Nurse radiation doses were collected by real-time dosimeters during consecutive coronary angiography procedures and are reported as the personal dose equivalent (Hp10). Patient radiation doses were estimated using dose area product (DAP). Patient BMI was categorized in kg/m2 as <25.0, 25.0-29.9, 30.0-34.9, 35.0-39.9, and ≥40. Multiple regression analysis determined procedural factors independently association with nurse radiation doses. RESULTS In 643 consecutive coronary angiography procedures, patient radiation doses increased significantly across increasing patient BMI categories (p < 0.001). Compared to a patient BMI <25, a patient BMI ≥40 was associated with a 2.3-fold increase in DAP (p < 0.001). Significant differences were also observed in nurse radiation doses across patient BMI categories (p = 0.036). Compared to a patient BMI <25, a patient BMI ≥40 was associated with a 4.0-fold increase in nurse radiation dose (BMI < 25: 0.3 [0.1, 1.3] μSv; BMI ≥ 40: 1.2 [0.2, 2.9] μSv; p = 0.003). By multiple regression analysis, each 1-unit kg/m2 increase in patient BMI was associated with a 3.3% increase in nurse radiation dose (p = 0.002). CONCLUSIONS Patient BMI was significantly associated with nurse radiation doses during coronary angiography. These observations may have important implications on nurse radiation safety, especially in the setting of the ongoing obesity epidemic.

Abstract
Background Previous studies have reported a protective effect of obesity compared with normal body mass index (BMI) in patients undergoing percutaneous coronary intervention (PCI). However, it is unclear whether this effect extends to the extremely obese. In this large multicenter registry‐based study, we sought to examine the relationship between BMI and long‐term clinical outcomes following PCI, and in particular to evaluate the association between extreme obesity and long‐term survival after PCI. Methods and Results This cohort study included 25 413 patients who underwent PCI between January 1, 2005 and June 30, 2017, who were prospectively enrolled in the Melbourne Interventional Group registry. Patients were stratified by World Health Organization–defined BMI categories. The primary end point was National Death Index–linked mortality. The median length of follow‐up was 4.4 years (interquartile range 2.0‐7.6 years). Of the study cohort, 24.8% had normal BMI (18.5‐24.9 kg/m2), and 3.3% were extremely obese (BMI ≥40 kg/m2). Patients with greater degrees of obesity were younger and included a higher proportion of diabetics (P<0.001). After adjustment for age and comorbidities, a J‐shaped association was observed between different BMI categories and adjusted hazard ratio (HR) for long‐term mortality (normal BMI, HR 1.00 [ref]; overweight, HR 0.85, 95% CI 0.78‐0.93, P<0.001; mild obesity, HR 0.85, 95% CI 0.76‐0.94, P=0.002; moderate obesity, HR 0.95, 95% CI 0.80‐1.12, P=0.54; extreme obesity HR 1.33, 95% CI 1.07‐1.65, P=0.01). Conclusions An obesity paradox is still apparent in contemporary practice, with elevated BMI up to 35 kg/m2 associated with reduced long‐term mortality after PCI. However, this protective effect appears not to extend to patients with extreme obesity.

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.

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 Limiting the contrast volume to creatinine clearance (V/CrCl) ratio is crucial for preventing contrast-induced acute kidney injury (CI-AKI) after percutaneous coronary intervention (PCI). However, the incidence of CI-AKI and the distribution of V/CrCl ratios may vary according to patient body habitus. Objective We aimed to identify the clinical factors predicting CI-AKI in patients with different body mass indexes (BMIs). Methods We evaluated 8782 consecutive patients undergoing PCI and who were registered in a large Japanese database. CI-AKI was defined as an absolute serum creatinine increase of 0.3 mg/dL or a relative increase of 50%. The effect of the V/CrCl ratio relative to CI-AKI incidence was evaluated within the low- (≤25 kg/m2) and high- (>25 kg/m2) BMI groups, with a V/CrCl ratio > 3 considered to be a risk factor for CI-AKI. Results A V/CrCl ratio > 3 was predictive of CI-AKI, regardless of BMI (low-BMI group: odds ratio [OR], 1.77 [1.42–2.21]; P < 0.001; high-BMI group: OR, 1.67 [1.22–2.29]; P = 0.001). The relationship between BMI and CI-AKI followed a reverse J-curve relationship, although baseline renal dysfunction (creatinine clearance <60 mL/min, 46.9% vs. 21.5%) and V/CrCl ratio > 3 (37.3% vs. 20.4%) were predominant in the low-BMI group. Indeed, low BMI was a significant predictor of a V/CrCl ratio > 3 (OR per unit decrease in BMI, 1.08 [1.05–1.10]; P < 0.001). Conclusions A V/CrCl ratio > 3 was strongly associated with the occurrence of CI-AKI. Importantly, we also identified a tendency for physicians to use higher V/CrCl ratios in lean patients. Thus, recognizing this trend may provide a therapeutic target for reducing the incidence of CI-AKI.

Impact of patient obesity on radiation doses received by scrub technologists during coronary angiography. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2018; 19:929-933.

Abstract
BACKGROUND The impact of patient obesity on scrub technologist radiation dose during coronary angiography has not been adequately studied. METHODS Real-time radiation exposure data were prospectively collected during consecutive coronary angiography cases. Patient radiation dose was estimated by dose area product (DAP). Technologist radiation dose was recorded by a dosimeter as the personal dose equivalent (Hp (10)). Patients were categorized according to their body mass index (BMI): <25.0, lean; 25.0-29.9, overweight; ≥30.0, obese. The study had two phases: in Phase I (N = 351) standard radiation protection measures were used; and in Phase II (N = 268) standard radiation protection measures were combined with an accessory lead shield placed between the technologist and patient. RESULTS In 619 consecutive coronary angiography procedures, significant increases in patient and technologist radiation doses were observed across increasing patient BMI categories (p < 0.001 for both). Compared to lean patients, patient obesity was associated with a 1.7-fold increase in DAP (73.0 [52.7, 127.5] mGy × cm2 vs 43.6 [25.1, 65.7] mGy × cm2, p < 0.001) and a 1.8-fold increase in technologist radiation dose (1.1 [0.3, 2.7] μSv vs 0.6 [0.1, 1.6] μSv, p < 0.001). Compared to Phase I, use of an accessory lead shield in Phase II was associated with a 62.5% reduction in technologist radiation dose when used in obese patients (p < 0.001). CONCLUSIONS During coronary angiography procedures, patient obesity was associated with a significant increase in scrub technologist radiation dose. This increase in technologist radiation dose in obese patients may be mitigated by use of an accessory lead shield.

The Relationship of Body Mass Index to Percutaneous Coronary Intervention Outcomes: Does the Obesity Paradox Exist in Contemporary Percutaneous Coronary Intervention Cohorts? Insights From the British Cardiovascular Intervention Society Registry. JACC Cardiovasc Interv 2018; 10:1283-1292. [PMID: 28683933 DOI: 10.1016/j.jcin.2017.03.013] [Citation(s) in RCA: 69] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2016] [Revised: 02/09/2017] [Accepted: 03/09/2017] [Indexed: 01/01/2023]
Abstract
OBJECTIVES The aims of this study were to examine the relationship between body mass index (BMI) and clinical outcomes following percutaneous coronary intervention (PCI) and to determine the relevance of different clinical presentations requiring PCI to this relationship. BACKGROUND Obesity is a growing problem, and studies have reported a protective effect from obesity compared with normal BMI for adverse outcomes after PCI. METHODS Between 2005 and 2013, 345,192 participants were included. Data were obtained from the British Cardiovascular Intervention Society registry, and mortality data were obtained through the U.K. Office of National Statistics. Multiple logistic regression was performed to determine the association between BMI group (<18.5, 18.5 to 24.9, 25 to 30 and >30 kg/m2) and adverse in-hospital outcomes and mortality. RESULTS At 30 days post-PCI, significantly lower mortality was seen in patients with elevated BMIs (odds ratio [OR]: 0.86 [95% confidence interval (CI): 0.80 to 0.93] 0.90 [95% CI: 0.82 to 0.98] for BMI 25 to 30 and >30 kg/m2, respectively). At 1 year post-PCI, and up to 5 years post-PCI, elevated BMI (either overweight or obese) was an independent predictor of greater survival compared with normal weight (OR: 0.70 [95% CI: 0.67 to 0.73] and 0.73 [95% CI: 0.69 to 0.77], respectively, for 1 year; OR: 0.78 [95% CI: 0.75 to 0.81] and 0.88 [95% CI: 0.84 to 0.92], respectively, for 5 years). Similar reductions in mortality were observed for the analysis according to clinical presentation (stable angina, unstable angina or non-ST-segment elevation myocardial infarction, and ST-segment elevation myocardial infarction). CONCLUSIONS A paradox regarding the independent association of elevated BMI with reduced mortality after PCI is still evident in contemporary U.K. practice. This is seen in both stable and more acute clinical settings.

Abstract
Objective The aim of this study was to assess the baseline clinical characteristics, coronary angiographic features, and adverse cardiovascular events during hospitalization and at 1 year of follow-up in obese patients compared with overweight and normal/underweight patients. Methods A prospective, multicenter study of consecutive patients undergoing percutaneous coronary intervention was performed. Results Of 2425 enrolled patients, 699 (28.8%) were obese, 1178 (48.6%) were overweight, and 548 (22.6%) were normal/underweight. Obese patients were more likely to be female and to have a higher prevalence of diabetes, hypertension, hypercholesterolemia, or previous percutaneous coronary intervention. Acute coronary syndrome was the indication for percutaneous coronary intervention in 77.0% of obese, 76.4% of overweight, and 77.4% of normal/underweight patients. No significant differences in the prevalence of multi-vessel coronary artery disease or multi-vessel percutaneous coronary intervention were found among the three groups. Additionally, no significant differences were found in stent thrombosis, readmission bleeding rates, or cardiac mortality among the three groups during hospitalization, at 1 month, and at 1 year. Conclusion The major adverse cardiovascular event rate was the same among the three groups throughout the study period. Accordingly, body mass index is considered a weak risk factor for cardiovascular comorbidities in Arab Jordanian patients.

Abstract
BACKGROUND With increasing rates of obesity and its link with cardiovascular disease, there is a need for better understanding of the obesity-outcome relationship. This study explores the association between categories of obesity with treatment times and mortality for patients experiencing ST-segment elevation myocardial infarction. METHODS AND RESULTS We examined 8725 patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention and used regression models to analyze the relationship between 6 categories of body mass index with key door-to-balloon time, total ischemic time, and in-hospital mortality. We relied on data from the Mission: Lifeline North Texas program, consisting of 33 percutaneous coronary intervention-capable hospitals in 6 counties surrounding Dallas, Texas. Data were extracted from the National Cardiovascular Data Registry for each participating hospital. Of the samples, 76% were overweight or obese. Comparing the univariate differences between the normal-weight group and the pooled sample, we observed a U-shaped association between body mass index and both mortality and door-to-balloon times. The most underweight and severely obese had the highest mortality and median door-to-balloon time, respectively. These differences persisted after multivariate adjustments for door-to-balloon time, but not for mortality. CONCLUSIONS Extremely obese patients have longer treatment time delays than other body mass index categories. However, this did not extend to significant differences in mortality in the multivariate models. We conclude that clinicians should incorporate body mass assessments into their diagnosis and treatment plans to mitigate observed disparities.

Abstract
BACKGROUND The risks of percutaneous coronary intervention (PCI) in obese and particularly morbidly obese patients remain uncertain. METHODS 1082 consecutive patients were categorised as non-obese (NO, body mass index (BMI) <30kg/m2, n=688), obese (O, BMI 30-40kg/m2, n=354) or morbidly obese (MO, BMI ≥40kg/m2, n=40). Demographic and procedural information was collated. Monte Carlo simulations modelled radiation dosimetric data. RESULTS Obese and morbidly obese patients were younger (p=0.016), more frequently female (p=0.036), more frequently diabetic (p<0.0001), with better renal function (p<0.0001), and prior PCI (p=0.01). There was no difference in major adverse cardiovascular or cerebrovascular events (MACCE) (NO=1.2%, O=0.8%, MO=2.5%, p=NS), acute kidney injury, bleeding, length of stay, 30-day readmission or 30-day mortality. Obese and morbidly obese patients received increased contrast (NO=180 [150-230]mL, O=190 [160-250]mL, MO=200 [165-225]mL, p=0.016), dose area product (NO=75.56 [50.61-113.69]Gycm2, O=116.4 [76.11-157.82]Gycm2, MO=125.62 [92.22-158.81]Gycm2, p<0.0001), entrance air kerma (NO=1439.42 [977.0-2075.5]mGy, O=2111.63 [1492.0-3011.0]mGy, MO=2376.0 [1700.0-3234.42]mGy, p<0.0001), and peak skin dose (NO=1439.42 [977.0-2075.5], O=2111.63 [1492.0-3011.0], MO=2376.0 [1700.0-3234.42], p<0.0001). Effective radiation dose increased in obese patients (NO=20.9±14.9mSv, O=27.4±17.1mSv, MO=24.1±12.6mSv, p<0.0001 for NO vs O, p=0.449 for NO vs MO). CONCLUSIONS Percutaneous coronary intervention can be performed in obese and morbidly obese patients without elevated risk for most clinical outcomes. However, radiation increases above levels that could cause both transient and late effects. Strategies should be pursued to minimise radiation dose.

Outcomes of Patients With Atrial Fibrillation Undergoing Percutaneous Coronary Intervention. J Am Coll Cardiol 2017; 68:895-904. [PMID: 27561762 DOI: 10.1016/j.jacc.2016.05.085] [Citation(s) in RCA: 55] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2015] [Revised: 04/26/2016] [Accepted: 05/18/2016] [Indexed: 11/22/2022]
Abstract
BACKGROUND Atrial fibrillation (AF) is increasing in prevalence, and patients with a history of AF commonly undergo percutaneous coronary intervention (PCI). There is a paucity of contemporary data on the association between AF and clinical outcomes after PCI. OBJECTIVES The study sought to evaluate the association between AF and in-hospital adverse outcomes using a large, prospective multicenter registry. METHODS Data for consecutive PCI cases from 47 hospitals performed between April 2011 and December 2014 were utilized for the analysis. Propensity-matched multivariate analysis was used to adjust for differences in baseline characteristics between patients with and without a history of AF. RESULTS Of 113,283 PCI cases during the study period, a history of AF was present in 13,912 patients (12%), which varied by institution (range 2.5% to 18.4%). At baseline, patients with a history of AF were older and were more likely to have comorbid congestive heart failure, cardiomyopathy, cerebrovascular disease, and chronic lung disease. Patients with a history of AF were more likely to have in-hospital complications, including in-hospital mortality (3% vs. 1%). In propensity-matched analysis, patients with a history of AF were more likely to be treated with a bare-metal stent (27% vs. 18%). In the propensity-matched model, AF remained independently associated with an increased risk of developing post-procedural bleeding (odds ratio [OR]: 1.32; 95% confidence interval [CI]: 1.15 to 1.52), heart failure (OR: 1.33; 95% CI: 1.17 to 1.52), cardiogenic shock (OR: 1.26; 95% CI: 1.08 to 1.48), and in-hospital mortality (OR: 1.41; 95% CI: 1.18 to 1.68). CONCLUSIONS AF is common among patients undergoing PCI. AF is associated with older age, the presence of other comorbidities, and independently associated with in-hospital post-procedural heart failure, cardiogenic shock, and mortality.

Abstract
OBJECTIVES This study sought to assess the impact of morbid obesity on outcomes in patients with in-hospital cardiac arrest (IHCA). BACKGROUND Obesity is associated with increased risk of out-of-hospital cardiac arrest; however, little is known about survival of morbidly obese patients with IHCA. METHODS Using the Nationwide Inpatient Sample database from 2001 to 2008, we identified adult patients undergoing resuscitation for IHCA, including those with morbid obesity (body mass index ≥40 kg/m2) by using International Classification of Diseases 9th edition codes and clinical outcomes. Outcomes including in-hospital mortality, length of stay, and discharge dispositions were identified. Logistic regression model was used to examine the independent association of morbid obesity with mortality. RESULTS Of 1,293,071 IHCA cases, 27,469 cases (2.1%) were morbidly obese. The overall mortality was significantly higher for the morbidly obese group than for the nonobese group experiencing in-hospital non-ventricular fibrillation (non-VF) (77% vs. 73%, respectively; p = 0.006) or VF (65% vs. 58%, respectively; p = 0.01) arrest particularly if cardiac arrest happened late (>7 days) after hospitalization. Discharge to home was significantly lower in the morbidly obese group (21% vs. 31%, respectively; p = 0.04). After we adjusted for baseline variables, morbid obesity remained an independent predictor of increased mortality. Other independent predictors of mortality were age and severe sepsis for non-VF and VF group and venous thromboembolism, cirrhosis, stroke, malignancy, and rheumatologic conditions for non-VF group. CONCLUSIONS The overall mortality of morbidly obese patients after IHCA is worse than that for nonobese patients, especially if IHCA occurs after 7 days of hospitalization and survivors are more likely to be transferred to a skilled nursing facility.

Impact of Body Mass Index on Short-Term Outcomes in Patients Undergoing Percutaneous Coronary Intervention in Newfoundland and Labrador, Canada. Cardiol Res Pract 2016; 2016:7154267. [PMID: 27668118 PMCID: PMC5030428 DOI: 10.1155/2016/7154267] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2016] [Revised: 07/21/2016] [Accepted: 07/25/2016] [Indexed: 11/23/2022] Open
Abstract
Background and Aim. Obesity (BMI ≥ 30 kg/m2) is associated with advanced cardiovascular disease requiring procedures such as percutaneous coronary intervention (PCI). Studies report better outcomes in obese patients having these procedures but results are conflicting or inconsistent. Newfoundland and Labrador (NL) has the highest rate of obesity in Canada. The aim of the study was to examine the relationship between BMI and vascular and nonvascular complications in patients undergoing PCI in NL. Methods. We studied 6473 patients identified in the APPROACH-NL database who underwent PCI from May 2006 to December 2013. BMI categories included normal, 18.5 ≤ BMI < 25.0 (n = 1073); overweight, 25.0 ≤ BMI < 30 (n = 2608); and obese, BMI ≥ 30.0 (n = 2792). Results. Patients with obesity were younger and had a higher incidence of diabetes, hypertension, and family history of cardiac disease. Obese patients experienced less vascular complications (normal, overweight, and obese: 8.2%, 7.2%, and 5.3%, p = 0.001). No significant differences were observed for in-lab (4.0%, 3.3%, and 3.1%, p = 0.386) or postprocedural (1.0%, 0.8%, and 0.9%, p = 0.725) nonvascular complications. After adjusting for covariates, BMI was not a significant factor associated with adverse outcomes. Conclusion. Overweight and obesity were not independent correlates of short-term vascular and nonvascular complications among patients undergoing PCI.

Abstract
BACKGROUND Stigma against the obese is well described in health care and may contribute to disparities in medical decision-making. It is unknown whether similar disparity exists for obese patients in cardiovascular care. We evaluated the association between body mass index (BMI) and prescription of guideline-recommended medications in patients undergoing elective percutaneous coronary intervention. METHODS AND RESULTS Using data from the Veterans Affairs Clinical Assessment, Reporting, and Tracking System Program, we identified patients undergoing elective percutaneous coronary intervention from 2007 to 2012, stratifying them by category of BMI. We described rates of prescription for class I guideline recommended medications for each BMI category (normal, overweight, and obese). Multivariable logistic regression assessed the association between BMI category and medication prescription. Seventeen thousand thirty-seven patients were identified, with 35.3% having overweight BMI, and 50.8% obese BMI. Obese patients were more likely than normal BMI patients to be prescribed β-blockers (OR 1.34), statins (OR 1.39), or ACE/ARB (odds ratio [OR] 1.52; all significant) when indicated. Overweight patients were more likely than normal BMI patients to be prescribed statins (OR 1.29) and angiotensin-converting enzymes/angiotensin II receptor blockers (OR 1.41) when indicated. There was no association between BMI category and prescription of anticoagulants. CONCLUSIONS Over 85% of patients undergoing elective percutaneous coronary intervention in the Veterans Affairs are overweight or obese. Rates of guideline-indicated medication prescription were <70% among all patients, and across BMI categories, with an association between increased BMI and greater use of guideline-recommended medications. Our findings offer a possible contribution to the obesity paradox seen in many cardiovascular conditions.

Abstract
OBJECTIVES Body mass index (BMI) commonly is used in obesity classification as a surrogate measure, and obesity is associated with a cluster of risk factors for cardiovascular disease. The aim of this study was to investigate the impact of BMI on short-term outcomes after cardiac surgery. DESIGN A retrospective cohort study. SETTING University teaching hospital, 2 centers. PARTICIPANTS The study comprised 4,740 patients who underwent cardiac surgery at 2 hospitals-from July 1, 2001, to June 30, 2013, in 1 hospital and from September 1, 2003, to August 31, 2014, in a second hospital. INTERVENTIONS No changes to standard practice were required. MEASUREMENTS AND MAIN RESULTS Patients were assigned into 6 BMI groups as follows: underweight (BMI<18.5 kg/m(2)), normal weight (≥18.5 to<25 kg/m(2)), overweight (≥25 to<30 kg/m(2)), class I obese (≥30 to<35 kg/m(2)), class II obese (≥35 to<40 kg/m(2)), and class III obese (BMI≥40 kg/m(2)). Short-term major postoperative complications (postoperative stroke, cardiac arrest, new atrial fibrillation/flutter, permanent rhythm device insertion, deep sternal infection, sepsis, prolonged ventilation, pneumonia, renal dialysis, renal failure, intensive care unit readmission, total intensive care unit hours, and readmission in 30 days, and mortalities (in-hospital mortality, 30-day mortality, surgical mortality) were compared among various BMI groups after cardiac surgery. Age, sex, surgery type, family history of coronary artery disease, diabetes, hypertension, heart failure, and lipid-lowering medication were the risk factors for early outcomes. Multiple logistic regression analysis indicated that the underweight and class III obese BMI groups demonstrated significant, adverse differences in some short-term outcomes, including deep sternal infection, prolonged ventilation, new atrial fibrillation/flutter, and renal failure. However, being in the overweight or class I obese group demonstrated a positive effect on discharge and surgical mortality. CONCLUSIONS The results of this study demonstrated that extreme obesity and underweight were significantly associated with early major adverse clinical outcomes. However, there was an "obese paradox" in short-term mortality after cardiac surgery.

Abstract
With the increasing prevalence of obesity, clinicians are now facing a growing population of patients with specific features of clinical presentation, diagnostic challenges, and interventional, medical, and surgical management. After briefly discussing the effect of obesity on atherosclerotic burden in this review, we will focus on strategies clinicians might use to ensure better outcomes when performing revascularization in obese and severely obese patients. These patients tend to present comorbidities at a younger age, and their anthropometric features might limit the use of traditional cardiovascular risk stratification approaches for ischemic disease. Alternative techniques have emerged, especially in nuclear medicine. Positron emission tomography-computed tomography might be the diagnostic imaging technique of choice. When revascularization is considered, features associated with obesity must be considered to guide therapeutic strategies. In percutaneous coronary intervention, a radial approach should be favoured, and adequate antiplatelet therapy with new and more potent agents should be initiated. Weight-based anticoagulation should be contemplated if needed, with the use of drug-eluting stents. An "off-pump" approach for coronary artery bypass grafting might be preferable to the use of cardiopulmonary bypass. For patients who undergo bilateral internal thoracic artery grafting, harvesting using skeletonization might prevent deep sternal wound infections. In contrast to percutaneous coronary intervention, lower surgical bleeding has been observed when lean body mass is used for perioperative heparin dose determination.

Abstract
OBJECTIVE To investigate the relationship of body mass index (BMI) with total mortality, cardiovascular (CV) mortality, and myocardial infarction (MI) after coronary revascularization procedures (coronary artery bypass grafting [CABG] and percutaneous coronary intervention [PCI]). PATIENTS AND METHODS Systematic search of studies was conducted using PubMed, CINAHL, Cochran CENTRAL, Scopus, and the Web of Science databases. We identified studies reporting the rate of MI, CV mortality, and total mortality among coronary artery disease patients' postcoronary revascularization procedures in various BMI categories: less than 20 (underweight), 20-24.9 (normal reference), 25-29.9 (overweight), 30-34.9 (obese), and 35 or more (severely obese). Event rates were compared using a random effects model assuming interstudy heterogeneity. RESULTS A total of 36 studies (12 CABG; 26 PCI) were selected for final analyses. The risk of total mortality (relative risk [RR], 2.59; 95% CI, 2.09-3.21), CV mortality (RR, 2.67; 95% CI, 1.63-4.39), and MI (RR, 1.79; 95% CI, 1.28-2.50) was highest among patients with low BMI at the end of a mean follow-up period of 1.7 years. The risk of CV mortality was lowest among overweight patients (RR, 0.81; 95% CI, 0.68-0.95). Increasing degree of adiposity as assessed by BMI had a neutral effect on the risk of MI for overweight (RR, 0.92; 95% CI, 0.84-1.01), obese (RR, 0.99; 95% CI, 0.85-1.15), and severely obese (RR, 0.93; 95% CI, 0.78-1.11) patients. CONCLUSION After coronary artery disease revascularization procedures (PCI and CABG), the risk of total mortality, CV mortality, and MI was highest among underweight patients as defined by low BMI and CV mortality was lowest among overweight patients.

Abstract
Obesity has been increasing in epidemic proportions, with a disproportionately higher increase in morbid or class III obesity, and obesity adversely affects cardiovascular (CV) hemodynamics, structure, and function, as well as increases the prevalence of most CV diseases. Progressive declines in physical activity over 5 decades have occurred and have primarily caused the obesity epidemic. Despite the potential adverse impact of overweight and obesity, recent epidemiological data have demonstrated an association of mild obesity and, particularly, overweight on improved survival. We review in detail the obesity paradox in CV diseases where overweight and at least mildly obese patients with most CV diseases seem to have a better prognosis than do their leaner counterparts. The implications of cardiorespiratory fitness with prognosis are discussed, along with the joint impact of fitness and adiposity on the obesity paradox. Finally, in light of the obesity paradox, the potential value of purposeful weight loss and increased physical activity to affect levels of fitness is reviewed.
