Project description:OBJECTIVES:This study sought to evaluate the influence of race/ethnicity on the relationship between body mass index (BMI) and mortality in heart failure with preserved ejection fraction (HFpEF) and HF with reduced EF (HFrEF) patients. BACKGROUND:Prior studies demonstrated an "obesity paradox" among overweight and obese patients, where they have a better HF prognosis than normal weight patients. Less is known about the relationship between BMI and mortality among diverse patients with HF, particularly given disparities in obesity and HF prevalence. METHODS:The authors used Get With The Guidelines-Heart Failure data to assess the relationship between BMI and in-hospital mortality by using logistic regression modeling. The authors assessed 30-day and 1-year rates of all-cause mortality following discharge by using Cox regression modeling. RESULTS:A total of 39,647 patients with HF were included (32,434 [81.8%] white subjects; 3,809 [9.6%] black subjects; 1,928 [4.9%] Hispanic subjects; 544 [1.4%] Asian subjects; and 932 [2.3%] other subjects); 59.7% of subjects had HFpEF, and 30.7% were obese. More black and Hispanic patients had Class I or higher obesity (BMI ?30 kg/m2) than whites, Asians, or other racial/ethnic groups (p < 0.0001). Among subjects with HFpEF, higher BMI was associated with lower 30-day mortality, up to 30 kg/m2 with a small risk increase above 30 kg/m2 (BMI: 30 vs. 18.5 kg/m2), hazard ratio (HR) of 0.63 (95% confidence interval [CI]: 0.54 to 0.73). A modest relationship was observed in HFrEF subjects (BMI: 30 vs. 18.5 kg/m2; HR: 0.73; 95% CI: 0.60 to 0.89), with no risk increase above 30 kg/m2. There were no significant interactions between BMI and race or ethnicity related to 30-day mortality (p > 0.05). CONCLUSIONS:This work is one of the first suggesting the obesity paradox for 30-day mortality exists at all BMI levels in HFrEF but not in patients with HFpEF. Higher BMI was associated with lower 30-day mortality across racial/ethnic groups in a manner inconsistent with the J-shaped relationship noted for coronary artery disease. The differential slope of obesity and mortality among HFpEF and patients with HFrEF potentially suggests differing mechanistic factors, requiring further exploration.

Project description:ObjectivesThis study sought to determine the degree to which U.S. patients enrolled in a heart failure (HF) trial represent patients in routine U.S. clinical practice according to race and sex.BackgroundBlack patients and women are frequently under-represented in HF clinical trials. However, the degree to which black patients and women enrolled in trials represent such patients in routine practice is unclear.MethodsThe ASCEND-HF (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure) trial randomized patients hospitalized for HF to receive nesiritide or placebo from May 2007 to August 2010 and was neutral for clinical endpoints. This analysis compared non-Hispanic white (n = 1,494) and black (n = 1,012) patients enrolled in ASCEND-HF from the U.S. versus non-Hispanic white and black patients included in a U.S. hospitalized HF registry (i.e., Get With The Guidelines-Heart Failure [GWTG-HF]) during the ASCEND-HF enrollment period and meeting trial eligibility criteria.ResultsAmong 79,291 white and black registry patients, 49,063 (62%) met trial eligibility criteria (white, n = 37,883 [77.2%]; black, n = 11,180 [22.8%]). Women represented 35% and 49% of the ASCEND-HF and trial-eligible GWTG-HF cohorts, respectively. Compared with trial-enrolled patients, trial-eligible GWTG-HF patients tended to be older with higher blood pressure and higher ejection fraction. Trial-eligible patients had higher in-hospital mortality (2.3% vs. 1.3%), 30-day readmission (20.2% vs. 16.8%), and 180-day mortality (21.2% vs. 18.6%) than those enrolled in the trial (all p < 0.02), with consistent mortality findings by race and sex. After propensity score matching, mortality rates were similar; however, trial-eligible patients continued to have higher rates of 30-day readmission (23.1% vs. 17.3%; p < 0.01), driven by differences among black patients and women (all p for interaction ≤0.02).ConclusionsPatients with HF seen in U.S. practice and eligible for the ASCEND-HF trial had worse clinical outcomes than those enrolled in the trial. After accounting for clinical characteristics, trial-eligible real-world patients continued to have higher rates of 30-day readmission, driven by differences among black patients and women. Social, behavioral, and other unmeasured factors may impair representativeness of patients enrolled in HF trials, particularly among racial/ethnic minorities and women.

Project description:Hepatorenal dysfunction is a strong risk factor in patients with heart failure (HF). We investigated the prognostic significance of hepatorenal dysfunction in 172 consecutive patients undergoing transcatheter tricuspid valve repair (TTVR). The model for end-stage liver disease excluding international normalized ratio (MELD-XI) score was calculated as 5.11 × ln(serum total bilirubin [mg/dl]) + 11.76 × ln(serum creatinine [mg/dl]) + 9.44. Patients were stratified into two groups: high (≥ 14) or low (< 14) MELD-XI score, according to the best cut-off value to predict a one-year composite outcome consisting of all-cause mortality and HF hospitalization. Compared to patients with low MELD-XI score (n = 121), patients with high MELD-XI score (n = 51) had a higher incidence of the composite outcome (47.1% vs. 17.4%; p < 0.0001). In the multivariable analysis, the MELD-XI score was an independent predictor of the composite outcome (adjusted hazard ratio: 1.12; 95% confidence interval [CI] 1.05-1.19; p = 0.0003). In addition, post-procedural TR < 3 + after TTVR was independently associated with a reduction in MELD-XI score six months after TTVR (adjusted odds ratio: 3.37; 95% CI 1.09-10.40; p = 0.03). Thus, the MELD-XI score was associated with the risk of one-year composite outcome, consisting of mortality and HF hospitalization, after TTVR and may help the risk stratification in patients undergoing TTVR.

Project description:AimsIsolated tricuspid valve surgery (ITVS) is considered to be a high-risk procedure, but in-hospital mortality is markedly variable. This study sought to develop a dedicated risk score model to predict the outcome of patients after ITVS for severe tricuspid regurgitation (TR).Methods and resultsAll consecutive adult patients who underwent ITVS for severe non-congenital TR at 12 French centres between 2007 and 2017 were included. We identified 466 patients (60 ± 16 years, 49% female, functional TR in 49%). In-hospital mortality rate was 10%. We derived and internally validated a scoring system to predict in-hospital mortality using multivariable logistic regression and bootstrapping with 1000 re-samples. The final risk score ranged from 0 to 12 points and included eight parameters: age ≥70 years, New York Heart Association Class III-IV, right-sided heart failure signs, daily dose of furosemide ≥125 mg, glomerular filtration rate <30 mL/min, elevated bilirubin, left ventricular ejection fraction <60%, and moderate/severe right ventricular dysfunction. Tricuspid regurgitation mechanism was not an independent predictor of outcome. Observed and predicted in-hospital mortality rates increased from 0% to 60% and from 1% to 65%, respectively, as the score increased from 0 up to ≥9 points. Apparent and bias-corrected areas under the receiver operating characteristic curves were 0.81 and 0.75, respectively, much higher than the logistic EuroSCORE (0.67) or EuroSCORE II (0.63).ConclusionWe propose TRI-SCORE as a dedicated risk score model based on eight easy to ascertain parameters to inform patients and physicians regarding the risk of ITVS and guide the clinical decision-making process of patients with severe TR, especially as transcatheter therapies are emerging (www.tri-score.com).

Project description:BackgroundIn patients with mild to moderate functional tricuspid regurgitation (TR) and absence of right ventricular dysfunction or tricuspid annulus (TA) dilatation, there is currently no indication for concomitant tricuspid valve (TV) repair during elective mitral valve (MV) surgery. However, long-term results are conflicting. Here, we sought to determine the clinical outcome of this cohort, the rate of TR progression after MV surgery and the role of MV aetiology.MethodsPatients for elective MV surgery without concomitant TV repair were retrospectively analysed with longitudinal echocardiographic and clinical follow-up, focusing on TR progression and MV aetiology. Linear regression analysis was performed for change in TR at follow-up, using pre-determined variables and confounders.ResultsIn total 204 patients without TV repair were analysed. Development of more than moderate TR after a median of 3.1 [1.6-4.6] years was rarely seen: only in 2 out of 161 patients (1.2%) with known TR grade at follow-up. Overall, median preoperative and late postoperative TR grade were equal (p = 0.116). Subanalysis showed no significant difference in MV aetiology subgroups. Preoperative TR grade and male gender were inversely correlated to change in TR. Mortality was not influenced by the 1‑year postoperative TR severity.ConclusionOur data showed that in a study population of patients with mild to moderate TR undergoing MV surgery without concomitant TV repair, significant late TR was rarely seen. Based on our study, it is safe to waive concomitant TV repair in this specific patient cohort.

Project description:BackgroundThe prognostic significance of tricuspid regurgitation (TR) and right ventricular (RV) function in patients undergoing aortic valve replacement (AVR) for severe aortic stenosis (AS) is unknown. The aim of the present study was to evaluate the impact of TR and RV systolic dysfunction on early and late mortality in this setting.MethodsThis was a prospective single-center observational study. 465 consecutive patients who were referred to AVR for severe AS were investigated. Significant TR was defined as TR≥moderate by transthoracic echocardiography.ResultsAt baseline, significant TR was present in 26 (5.6%) patients. Patients with TR presented with a higher EuroSCORE I (p = 0.001), a higher incidence of previous cardiac surgery (p<0.001), pulmonary hypertension (p = 0.003), more dilated RVs (p = 0.001), and more frequent RV dysfunction (p = 0.001). Patients were followed for an average of 5.2 (±2.8 SD) years. By multivariable Cox regression analysis TR (p = 0.014), RV dysfunction (p = 0.046), age (p = 0.001) and concomitant coronary artery bypass graft surgery (CABG, p = 0.003) were independently associated with overall mortality. By Kaplan-Meier analysis, survival rates were significantly worse in patients with significant than with non-significant TR (log rank p = 0.001).ConclusionsTR, RV dysfunction, age, and concomitant CABG are associated with outcome in patients undergoing AVR for severe AS. This finding underlines the importance of a thorough echocardiographic evaluation with particular consideration of the right heart in these patients.

Project description:BackgroundBioprosthetic mitral valves on average have a median durability between 8 and 10 years. After the failure of a bioprosthetic valve, surgical replacement is often indicated. However, the options for those patients at high or prohibitive surgical risks are limited. Here, we describe a case of a successful trans-catheter mitral valve-in-valve (TMViV) replacement on venoarterial extracorporeal membrane oxygenation (VA-ECMO).Case summaryWe describe a case of a 39-year-old female with a history notable for systemic lupus erythematosus, severe pulmonary arterial hypertension (now mixed pre and post) thought to be secondary to prior substance use, and infective endocarditis complicated by severe mitral stenosis status post-bioprosthetic mitral valve replacement who presented with symptoms of acute hypoxic respiratory failure secondary to severe bioprosthetic mitral valve stenosis. The patient had a prolonged hospital course complicated by a pulseless electrical activity arrest, (continuous renal replacement therapy) for acute renal failure, and hypertonic saline due to cerebral oedema. Due to her significant co-morbidities and haemodynamic instability with acute kidney injury and recent neurologic insult, the patient was thought not to be a good surgical candidate. However, given her young age and overall improved neurologic status, it was thought the patient could benefit from a TMViV with bi-ventricular support given her right- and left-sided heart failure and was placed on VA-ECMO in anticipation of a TMViV procedure for circulatory support. The patient underwent a successful TMViV replacement using a trans-septal approach with a 26 mm SAPIEN 3 valve and atrial septal defect closure with a 14 mm Amplatzer device on hospital Day 12. The patient was successfully de-cannulated from VA-ECMO on hospital Day 13. The patient had a prolonged hospital course but eventually had renal recovery and tracheostomy de-cannulation. A trans-thoracic echocardiogram prior to discharge was notable for a well-functioning valve and normal ejection fraction. The patient was discharged to a nursing home for further rehabilitation.DiscussionThe gold standard for bioprosthetic mitral valve stenosis is surgical replacement of the valve. However, the options for those at high or prohibitive surgical risk are lacking. Recent studies have demonstrated TMViV is a safe alternative to surgical mitral valve redo cases in high-risk patients. To our knowledge, there are limited data on trans-catheter valve placement while on VA-ECMO. Successful implantation in our patient suggests that TMViV in a stenotic bioprosthesis is feasible in very high-risk patients with the use of VA-ECMO to support haemodynamics.

Project description:BackgroundThe impact of pulmonary hypertension (PH) on outcomes after surgical tricuspid valve replacement (TVR) and repair (TVr) is unclear. We sought to characterize PH in patients undergoing TVR/TVr, based on invasive hemodynamics and evaluate the effect of PH on mortality.MethodsWe identified 86 consecutive patients who underwent TVR/TVr with invasive hemodynamic measurements within 3 months before surgery. We used Kaplan-Meier survival and restricted mean survival time (RMST) analyses to quantify the effects of PH on survival.ResultsThe mean age was 63 ± 13 years, 59% were female, 45% had TVR, 55% had TVr, 39.5% had isolated TVR/TVr, and 60.5% had TVR/TVr concomitant with other cardiac surgeries). Eighty-six percent of these patients had PH with a mean pulmonary artery pressure of 30 ± 10 mm Hg, pulmonary vascular resistance (PVR) of 2.5 (interquartile range: 1.5-3.9) Wood units (WU), pulmonary arterial compliance of 2.3 (1.6-3.6) mL/mm Hg, and pulmonary arterial elastance of 0.8 (0.6-1.2) mm Hg/mL. Cardiac output was mildly reduced at 4.0 ± 1.4 L/min, with elevated right-atrial pressure (14 ± 12 mm Hg) and pulmonary capillary wedge pressure (19 ± 7 mm Hg). Over a median follow-up of 6.3 years, 22% of patients died. Patients with PVR ≥ 2.5 WU had lower RMST over 5 years compared with patients with PVR < 2.5 WU.ConclusionPH is common in patients undergoing TVR/TVr, with combined pre- and postcapillary being the most common type. PVR ≥ 2.5 WU is associated with lower survival at 5-year follow-up.

Project description:Systemic immune-inflammation index (SII, platelet × neutrophil/lymphocyte ratio) has recently been identified as an inflammatory marker. We aimed to evaluate the prognostic implications of preoperative SII in patients undergoing isolated tricuspid valve (TV) surgery. In total, 213 patients who underwent isolated TV surgery between January 2000 and December 2018 were enrolled. They were divided into two groups, as follows: low SII (<455.6 × 109/L), and high SII (≥455.6 × 109/L). The correlation between SII and clinical outcomes was analyzed via the Cox regression and the Kaplan-Meier analyses. The primary outcomes considered were all-cause mortality and major postoperative complications within a 30-day period after isolated TV surgery, including major adverse cardiovascular or cerebrovascular events, pulmonary and renal complications, stroke, sepsis, multi-organ failure, wound, and gastrointestinal complications. In total, 82 (38.5%) patients experienced postoperative complications. Multivariable analyses revealed that high preoperative SII values were independently associated with the major 30-day postoperative complications (hazard ratio 3.58, 95% confidence interval 1.62-7.95, p = 0.001). Additionally, Kaplan-Meier analysis revealed that the probability of undergoing major 30-day postoperative complications was significantly elevated in patients with high versus low SII values (p < 0.001). These results indicate that SII, a readily available parameter, is significantly associated with poor outcomes in patients undergoing isolated TV surgery.

Project description:Due to progressive abdominal-venous congestion severe tricuspid regurgitation (TR) is a common cause of cardiorenal and cardiohepatic syndrome. We initiated the TRICAVAL study to compare interventional valve implantation into the inferior vena cava (CAVI) versus optimal medical therapy (OMT) in severe TR. In the present subanalysis, we aimed to evaluate the effects of CAVI on clinical signs of congestion, renal and hepatic function. TRICAVAL was an investigator-initiated, randomized trial. Twenty-eight patients with severe TR were randomized to OMT or CAVI using an Edwards Sapien XT valve. Probands who completed the 3-month follow-up (CAVI [n = 8], OMT [n = 10]) were evaluated by medical history, clinical examination, and laboratory testing at baseline, 3 and 12 months. After 3 months, the CAVI group exhibited a significant reduction of body weight (from 80.7 [69.0-87.7] kg to 75.5 [63.8-84.6] kg, p < 0.05) and abdominal circumference (from 101.5 ± 13.8 cm to 96.3 ± 15.4 cm, p ≤ 0.01) and a trend to lower doses of diuretics compared to OMT. Renal and hepatic function parameters did not change significantly. Within a short-term follow-up, CAVI led to an improvement of clinical signs of venous congestion and a non-significant reduction of diuretic doses compared to OMT.
