Abstract Background Major adverse cardiovascular events (MACE) are useful endpoints to evaluate cardiovascular outcomes. The aim of this study was to report our results in concordance with the expected improvement of records after using the online Research Electronic Data Capture (RedCap) software. Methods: We included patients who benefited from first time elective isolated coronary bypass grafting (CABG) at Ain-Shams university main hospital, in the period between April 2014 and April 2016; providing a minimum 2 years follow-up . Incidences, risk factors and independent predictors for MACE were calculated including; mortality, the occurrence or re-hospitalization for: heart failure, recurrence of angina or myocardial infarction (MI), cerebrovascular stroke (CVS), need of coronary angiography (CA), repeat percutaneous intervention (PTCA) or CABG. Results: 607 cases met our inclusion criteria and 105 patients (18.7%) developed 184 MACE, including 45 hospital mortalities (7.4%), 13 late mortalities (2.1%) and 126 non-fatal events recorded in 47 patients (7.7%); a majority (40 patients; 6.6%) had suffered from at least 3 non-fatal events. Two-years follow-up was complete for the 562 hospital survivors with a total of 1113 patient-years. The annualized incidence rates of ICU admission, repeated angina or MI, need for CA, PTCA, or CABG, development of CVS, heart failure, and late mortality were: 3.6%, 2.8%, 1.8%, 0.5%, 0.09%, 0.35%, 2% and 1.2% per patient-year; respectively. Independent predictors of hospital mortality were: advanced age at surgery (OR 1.06: 1-1.12; P = 0.049), female sex (OR 3.4: 1.3-8.9; P = 0.01), prolonged durations of: cardiopulmonary bypass CPB (OR 1.02: 1.01- 1.04; P < 0.001), mechanical ventilation (OR 1.07: 1.04- 1.09; P < 0.001) positive inotropic support (OR 1.03: 1.02- 1.05; P < 0.001) and ICU stay (OR 1.09: 1.07- 1.11; P < 0.001). Independent predictors of overall MACE were advanced age at surgery (OR 1.04: 1.01-1.07; P = 0.011), prolonged durations of: aortic cross clamp (OR 1.09: 1.04-1.11; P = 0.003), CPB (OR 1.06: 1.04-1.08; P < 0.001) and mechanical ventilation (OR 1.02: 1.01-1.03; P < 0.001). Conclusion: Our results suggested that more care should be given to females, elderly and to shorten and improve the quality of our operative times. The repetition of non-fatal MACE could be modified by closer observation of the patient, once developing his first event.

AbstractBackgroundThe increase in soluble suppression of tumorigenicity 2 (sST2) both in the diagnosis and prognosis of heart failure is well established; however, existing data regarding sST2 values as the prognostic marker after myocardial infarction (MI) are limited and have been conflicting. This study aimed to assess the clinical significance of sST2 in predicting 1-year adverse cardiovascular (CV) events in MI patients.Materials and methodsIn this prospective study, 380 MI patients were included. Participants were grouped into low sST2 (n = 264, mean age: 60.0 ± 12.1 years) and high sST2 groups (n = 116, mean age: 60.5 ± 11.6 years), and all study populations were followed up for major adverse cardiovascular events (MACE) which are composed of CV mortality, target vessel revascularization (TVR), non-fatal reinfarction, stroke and heart failure.ResultsDuring a 12-month follow-up, 68 (17.8%) patients had MACE. CV mortality and heart failure were significantly higher in the high sST2 group compared to the low sST2 group (15.5% vs. 4.9%, p = 0.001 and 8.6% vs. 3.4% p = 0.032, respectively). Multivariate Cox regression analysis concluded that high serum sST2 independently predicted 1-year CV mortality [hazard ratio (HR) 2.263, 95% confidence interval (CI) 1.124–4.557, p = 0.022)]. Besides, older age, Killip class >1, left anterior descending (LAD) as the culprit artery and lower systolic blood pressure were the other independent risk factors for 1-year CV mortality.ConclusionsHigh sST2 levels are an important predictor of MACE, including CV mortality and heart failure in a 1-year follow-up period in MI patients.

Background: Cardiopulmonary exercise test (CPET) is a crucial tool for the functional evaluation of cardiac patients. We hypothesized that VO2 max and VE/VCO2 slope are not the only parameters of CPET able to predict major cardiac events (mortality or cardiac transplantation urgently or elective). Objectives: We aimed to identify the best CPET predictors of major cardiac events in patients with severe chronic heart failure and to propose an integrated score that could be applied for their prognostic evaluation. Methods: We evaluated 140 patients with chronic heart failure who underwent CPET between 2011 and 2019. Major cardiac events were evaluated during follow-up. Univariate and multivariate logistic regression analysis were applied to study the predictive value of different clinical, echocardiographic and CPET parameters in relation to the major cardiac events. A score was generated and c-statistic was used for the comparisons. Results: Thirty-nine patients (27.9%) died or underwent cardiac transplantation over a median follow-up of 48 months. Five parameters (maximal workload, breathing reserve, left ventricular ejection fraction, diastolic dysfunction and non-idiopathic cardiomyopathy) were used to generate a risk score that had better risk discrimination than NYHA dyspnea scale, VO2 max, VE/VCO2 slope > 35 alone, and combined VO2 max and VE/VCO2 slope (p= 0.009, 0.004, < 0.001 and 0.005 respectively) in predicting major cardiac events. Conclusions: A composite score of CPET and clinical/echocardiographic data is more reliable than the single use of VO2max or combined with VE/VCO2 slope to predict major cardiac events.

Background: Obesity can adversely affect most organ systems and increases the risk of comorbidities likely to be of consequence for patients with complex adult congenital heart disease (ACHD). Conversely, several studies have demonstrated that low body mass index (BMI) is a risk factor for heart failure and adverse outcomes after cardiac surgery. However, there are currently no data regarding the impact of BMI in ACHD. Methods: We examined the charts of 87 randomly selected, complex ACHD patients whose first visit to our institution was at 18-22 years old. Patients were categorized according to BMI at initial visit: underweight (BMI < 18.5 kg/m 2 ), normal (BMI 18.5 - 24.9 kg/m 2 ), overweight/obese (BMI ≥ 25 kg/m 2 ). Events occurring during follow-up were recorded. Data was censured on 1/1/2014. Cardiac events were defined as a composite of cardiac death, heart transplantation or admission for heart failure. Results: The cohort included patients with the following diagnoses: tetralogy of Fallot n=31, Mustard n=28, Fontan n=17, ccTGA n=9 and aortic coarctation n=2. The median (IQR) duration of follow-up was 8.7 (4.2 - 1.8) years. See table for distribution and outcomes by BMI category. Cardiac events occurred in 17/87 patients. After adjustment for age, sex, and underlying disease, the underweight group had increased risk of cardiac events (HR=12.9, 95% CI: 2.8-61.5, p < 0.05). Kaplan-Meier curves demonstrate the poorer prognosis of underweight patients (Figure). Conclusions: Underweight was associated with increased risk of late cardiac events in ACHD patients. We were unable to demonstrate significant overweight/obesity impact.

Introduction: Assessment of cardiac mechanics in relation to left atrial (LA) and ventricular (LV) structural (shape and volume) changes represent a foundation for assessing cardiac remodeling in heart failure (HF) patients. We tested the feasibility of assessing simultaneous LA and LV volumes and deformation within an index cardiac cycle as a marker of total left heart structural and functional remodeling in HF. Methods: Echocardiography was performed in total 101 patients, which included 77 patients with HF (50 had normal EF (HFNEF) and 27 had reduced EF (HFREF)) and 24 young subjects with no structural heart disease (controls) (table 1). Two-dimensional speckle tracking was performed in apical 2- and 4- chamber views for simultaneous measurement of LV and LA volumes and deformation. Peak longitudinal average atrio-ventricular strain (AVS) and early diastolic strain rate (AVSR-E), in addition to the total left heart volume (TLV) during LV systole and diastole (TLVsystole, TLVdiastole), were measured. Occurrence of major adverse cardiac events (MACE) was defined during follow up. Results: In comparison with younger controls, patient with HF showed higher TLV and nearly 50% reduction in AVS and AVSR-E (table 1). These differences persisted even after adjusting for age. During a median follow up of 7 months, MACE occurred in 15 patients (5 hospitalization for heart failure, 1 cerebrovascular stroke, and 9 cardiac deaths). AVS and AVSR-E were predictors for MACE after adjusting for age (HR=0.9, 95% CI: 0.81 to 0.99, p=0.038; HR= 0.14, 95% CI: 0.02 to 0.89, p=0.037; respectively). AVS and AVSR-E had similar diagnostic values in predicting MACE (AUC= 0.77 and 0.79; p=0.001 and <0.001 respectively), with higher event free survival seen for AV-S>14.5%, and AVSR-E>0.92 s-1 (Figure 1). Conclusion: Single beat combined assessments of LA-LV strain and strain rates may be useful integrated markers of total left heart function.

Abstract Purposes We examined how changes in left ventricular (LV) global longitudinal strain (GLS) were associated with prognosis in patients with preserved LV ejection fraction (LVEF) after congestive heart failure (HF) admission. Methods We studied 123 consecutive patients (age 70 ± 15 years, 55% male) who had been hospitalized due to congestive HF with preserved LVEF (&gt; 50%). The exclusion criteria were atrial fibrillation and inadequate echo image quality for strain analyses. The patients underwent speckle-tracking echocardiography and measurement of plasma NT-ProBNP levels on the same day at the time of hospital admission as well as in the stable condition after discharge. Differences in GLS, LVEF and NT-ProBNP (delta GLS, LVEF and NT-ProBNP ; 2nd – 1st measurements) were calculated. The study end points were all-cause mortality and cardiac events. Results Mean periods of echo performance after hospitalization were 2 ±１days (1st echo) and 240 ± 289 days (2nd echo), respectively. During the follow-up (974 ± 626 days), 12 patients died and 25 patients were hospitalized because of HF worsening. In multivariate analysis, delta GLS and follow-up GLS were prognostic factors, whereas baseline and follow-up LVEF, NT-ProBNP, changes in LVEF and NT-ProBNP could not predict cardiac events. Delta GLS (p = 0.002) turned out to be the best independent prognosticator. Receiver operating characteristics analysis revealed that -0.6% of delta GLS was the optimal cut-off value to predict cardiac events and mortality (sensitivity 76%, specificity 67%, AUC 0.75). Kaplan-Meier analysis showed that patients with delta GLS more than -0.6% experienced significantly less cardiac events during the follow-up period (p &lt; 0.0001, log-rank). Conclusion A change in LV GLS after congestive HF admission was a predictor of the prognosis in patients with preserved LVEF. It would be useful to check the changes in GLS in those with preserved LVEF after discharge.

Abstract Background Percutaneous mitral valve repair using MitraClip offers symptomatic benefit and improves rest and exercise hemodynamics in patients with severe functional mitral regurgitation (MR). Recent randomized trials have shown contradictory results regarding the impact of MitraClip on mid-term survival in functional MR. It is unknown whether improved hemodynamics are related to patients" outcome. Purpose To assess whether residual MR and altered resting and exercise hemodynamics are predictors of outcome in patients with functional MR treated with MitraClip. Methods Consecutive patients (n = 45, 72 ± 10years, left ventricular ejection fraction (LVEF) 34 ± 9%) with symptomatic severe functional MR were prospectively evaluated by Doppler echocardiography at rest and during symptom-limited exercise on a semi-supine bicycle pre- and 6 months post-MitraClip procedure. LVEF, MR severity, cardiac output (CO), systolic pulmonary artery pressure (SPAP) and a flow-corrected SPAP/CO ratio were assessed at rest and peak exercise. 2-year follow-up clinical data were collected from patient records. Results During 2-year follow-up post-MitraClip, 15 patients (33%) experienced major cardiac events (hospitalization for heart failure (n = 14) and/or cardiac death (n = 5)). Age, gender, a history of coronary artery disease, diabetes, baseline MR severity and baseline SPAP/CO ratio at rest and during exercise were not related to a worse event-free survival. In contrast, patients with events at 2-year follow up had more often a history of hospitalization for heart failure (73 vs. 37%, p = 0.029), lower baseline LVEF (30 ± 8 vs. 36 ± 10%, p = 0.041), more residual MR at 6 months post-MitraClip (MR jet area/left atrial area 27 ± 14 vs. 15 ± 10%, p = 0.004) and higher SPAP/CO ratios at rest and during exercise 6 months post-MitraClip (13.9 ± 5.3 vs. 9.9 ± 3.4mmHg/L/min, p = 0.007 and 13.6 ± 4.9 vs. 9.4 ± 4.6mmHg/L/min, p = 0.009, respectively). When corrected for baseline LVEF, residual MR 6 months post-MitraClip remained an independent predictor for worse 2-year outcome. Residual MR was moderately correlated to a worse SPAP/CO ratio 6 months post-MitraClip (Pearson Rho 0.518, p &lt; 0.001). Conclusions In patients with functional MR treated with MitraClip, residual MR at 6-month follow-up is associated with impaired hemodynamics, and is an independent predictor of cardiac events at 2-year follow-up.

Waist To Hip Ratio

Background: Heart failure (HF) is considered one of the most common complications of coronary heart disease (CHD), with a higher incidence of readmission and mortality. Thus, exploring the risk factors related to the prognosis is necessary. Moreover, the effect of the waist-to-hip ratio (WHR) on HF patients with revascularized CHD is still unclear. Thus, we aimed to assess the influence of WHR on the prognosis of HF patients with revascularized CHD.Methods: We collected data of HF patients with revascularized CHD who were referred to the Cardiac Rehabilitation Clinic of PLA Hospital from June 30, 2015, to June 30, 2019. Cox proportional hazard regression analysis was used to determine the relationship between WHR and prognosis of HF patients with revascularized CHD. Patients were divided into higher and lower WHR groups based on the cutoff WHR value calculated by the X-tile software. Cox regression analysis was used to analysis the two groups. We drew the receiver operating characteristic curve (ROC) of WHR and analyzed the differences between the two groups. Endpoints were defined as major adverse cardiac events (MACE) (including all-cause mortality, non-fatal myocardial infarction, unscheduled revascularization, and stroke).Results: During the median follow-up of 39 months and maximum follow-up of 54 months, 109 patients were enrolled, of which 91.7% were males, and the mean age was 56.0 ± 10.4 years. WHR was associated with the incidence of MACE in the Cox regression analysis (p = 0.001); an increase in WHR of 0.01 unit had a hazard ratio (HR) of 1.134 (95%CI: 1.057–1.216). The WHR cutoff value was 0.93. Patients in the higher WHR group had a significantly higher risk of MACE than those in the lower WHR group (HR = 7.037, 95%CI: 1.758–28.168). The ROC area under the curve was 0.733 at 4 years. Patients in the higher WHR group had a higher body mass index (BMI; 26.7 ± 3.5 vs. 25.4 ± 2.4, P = 0.033) than patients in the lower WHR group.Conclusions: WHR is an independent risk factor of the long-term prognosis of Chinese HF patients with revascularized CHD. Patients with WHR ≥ 0.93 require intensified treatment. Higher WHR is related to higher BMI and ΔVO2/ΔWR.

Abstract Background One of the novel echocardiographic indices reflecting left ventricular (LV) diastolic filling is the combination of mitral annular peak systolic (s’) and early diastolic velocities (e’) with early transmitral peak flow velocity (E); E/(e’ x s’). This index is reported to be useful to predict a prognosis of heart failure patients regardless of their LV ejection fraction (LVEF).Purpose: The aim of this study was to examine whether or not E/(e’ x s’) could predict cardiac events in patients with acute coronary syndrome (ACS).Methods: We studies consecutive ACS patients hospitalized in our institution between December 2009 and February 2012. They underwent echo examination within 7 days after admission. By use of Doppler tissue imaging, e’ and s’ were respectively calculated by averaging the peak velocities measured at both septal and lateral mitral annulus in 4-chamber view. The exclusion criteria were as follows: atrial fibrillation, significant valvular diseases and inadequate echo images. Cardiac events were defined as re-hospitalization due to recurrent ACS and/or heart failure, and cardiac mortality.Results: In total, 168 patients were eligible for this study (mean age 67 ± 11 years, mean LVEF 51.7 ± 10.3 %). Median follow-up period was 22.5 months. During the follow-up, cardiac events occurred in 27 patients (16.1%). Between the patients with cardiac events and those without, there were significant differences in LV end-systolic volume (44.2 ± 29.1 vs 33.2 ± 13.6 ml, p &lt; 0.05), LV mass index (122.4 ± 38.9 vs 107.5 ± 26.4 g/m², p &lt; 0.05), left atrial volume index (31.7 ± 9.2 vs 27.6 ± 9.4 ml/m², p &lt; 0.05), LVEF (45.7 ± 13.5 vs 52.9 ± 9.2 %, p &lt; 0.05), s’ (5.1 ± 1.6 vs 7.1 ± 1.7 cm/sec, p &lt; 0.001), e’ (4.8 ± 1.3 vs 6.0 ± 1.9 cm/sec, p &lt; 0.05), E/e’ (16.4 ± 6.6 vs 12.5 ± 4.9, p &lt; 0.05), E/(e’ x s’) (3.78 ± 2.52 vs 1.94 ± 1.08, p &lt; 0.001), and serum B-type natriuretic peptide (334.7 ± 420.1 vs 113.8 ± 177.2 pg/ml, p &lt; 0.05). While Cox proportional hazard multivariate analysis detected that E/(e’ x s’) and E/e’ were independent predictors of cardiac events, E/(e’ x s’) was more powerful than E/e’ (p = 0.0002 vs p = 0.0072). ROC analysis revealed that 2.35 of E/(e’ x s’) was the optimal cutoff values to predict cardiac events in ACS patients (AUC 0.79). Patients with E/(e’ x s’) &lt;2.35 had significantly better prognosis than the rest (p &lt; 0.0001, Log-rank; Figure)Conclusion: E/(e’ x s’) could be a useful echo marker to predict cardiac events in ACS patients.

Midkine (MK), a heparin-binding growth factor, has various functions such as migration of inflammatory cell and anti-apoptotic effect. Invasion of inflammatory cells and cardiomyocyte apoptosis are involved in development and progression of heart failure (HF). However, relationship between MK and HF has not been previously examined. Therefore, we examined clinical significance of serum MK levels to determine the prognosis of HF patients. Serum levels of MK were measured at admission in 216 consecutive patients hospitalized for chronic HF and 60 control subjects. Patients were prospectively followed during a median follow-up period of 658 days with the end points of cardiac death and progressive HF requiring re-hospitalization. Serum concentrations of MK were significantly higher in patients with HF than in controls and increased as NYHA functional class rose (fig 1 ). There were 74 cardiac events, including 30 cardiac deaths and 44 re-hospitalization for HF during follow-up period. Patients with cardiac events had significantly higher concentrations of MK than those without cardiac events (539 ± 57 pg/ml vs. 331 ± 17 pg/ml, P < 0.01). Patients were divided into 4 groups based on midkine levels. Risk of cardiac events increased as MK levels rose (fig 2 ). In addition, the Cox multivariate hazard analysis showed that MK was an independent predictor of cardiac events (hazard ratio 1.280, 95% CI 1.027–1.578, P<0.05). Serum MK level is increased in HF patients, and MK is a novel marker for risk stratifying chronic HF patients. Figure 1. Serum Midkine Levels in Study Population Figure 2.

Background . In patients (pts) with chronic heart failure, late gadolinium enhancement cardiovascular magnetic resonance (LGE-CMR) is capable to distinguish left ventricular systolic dysfunction (LVSD) related or not to coronary artery disease (CAD). Moreover about 10% of pts with dilated cardiomyopathy (DCM) are actually «unrecognized » ischemic cardiomyopathy (ICM), possibly because of coronary recanalization after silent infarction. However, the prognostic implications of « unrecognized » ICM are not known. Methods. Three hundred consecutive pts with heart failure and LVSD underwent LGE-CMR and were followed prospectively during 833 days (12–2724). The primary endpoint was the composite of cardiac death or heart failure hospitalization. Pts were classified into 4 groups : DCM without LGE (N 149) ; DCM with midwall fibrosis (n 35) ; ICM : ischemic scar and CAD (n 81) ; « unrecognized » ICM : ischemic scar without CAD (n 30). Results. 111 pts (38%) experienced events during follow-up.. There were non significant differences in event rate in patients with « unrecognized » ICM and ICM (53% and 63% respectively). By contrast the event rate in ICM groups were significantly higher than in pts with DCM (29% in group 1 and 31% in group 2 ; p = 0.000001) (Figure ). By multivariate analysis LGE was the strongest predictor of cardiac events (HR 1,7 CI 95% 1.07–2.88). Conclusions . In our series, pts with « unrecognized » ICM detected by CMR had a high risk of cardiac events during follow up similar to those pts with ICM. These findings had potentially important implications for routine use of CMR as a diagnostic and prognostic tool in patients with heart failure and systolic dysfunction.
