Echocardiographic Parameters

Abstract Background Novel echocardiographic software allows for layer-specific evaluation of myocardial deformation by 2-dimensional speckle tracking echocardiography. Endocardial, epicardial- and whole wall global longitudinal strain (GLS) may be superior to conventional echocardiographic parameters in predicting all-cause mortality in patients with heart failure with reduced ejection fraction (HFrEF). Purpose The purpose of this study was to investigate the prognostic value of endocardial-, epicardial- and whole wall GLS in patients with HFrEF in relation to all-cause mortality. Methods We included and analyzed transthoracic echocardiographic examinations from 1,015 patients with HFrEF. The echocardiographic images were analyzed, and conventional and novel echocardiographic parameters were obtained. A p value in a 2-sided test <0.05 was considered statistically significant. Cox proportional hazards regression models were constructed, and both univariable and multivariable hazard ratios (HRs) were calculated. Results During a median follow-up time of 40 months, 171 patients (16.8%) died. A lower endocardial (HR 1.17; 95% CI (1.11–1.23), per 1% decrease, p<0.001), epicardial (HR 1.20; 95% CI (1.13–1.27), per 1% decrease, p<0.001), and whole wall (HR 1.20; 95% CI (1.14–1.27), per 1% decrease, p<0.001) GLS were all associated with higher risk of death (Figure 1). Both endocardial (HR 1.12; 95% CI (1.01–1.23), p=0.027), epicardial (HR 1.13; 95% CI (1.01–1.26), p=0.040) and whole wall (HR 1.13; 95% CI (1.01–1.27), p=0.030) GLS remained independent predictors of mortality in the multivariable models after adjusting for significant clinical parameters (age, sex, total cholesterol, mean arterial pressure, heart rate, ischemic cardiomyopathy, percutaneous transluminal coronary angioplasty and diabetes) and conventional echocardiographic parameters (left ventricular (LV) ejection fraction, LV mass index, left atrial volume index, deceleration time, E/e', E-velocity, E/A ratio and tricuspid annular plane systolic excursion). No other echocardiographic parameters remained an independent predictors after adjusting. Furthermore, endocardial, epicardial and whole wall GLS had the highest C-statistics of all the echocardiographic parameters. Conclusion Endocardial, epicardial and whole wall GLS are independent predictors of all-cause mortality in patients with HFrEF. Furthermore, endocardial, epicardial and whole wall GLS were superior prognosticators of all-cause mortality compared with all other echocardiographic parameters.

Overall Mortality

Background: Pulmonary transit time (PTT) from first-pass perfusion imaging is a novel parameter to evaluate hemodynamic congestion by cardiac magnetic resonance (cMR). We sought to evaluate the additional prognostic value of PTT in heart failure with reduced ejection fraction over other well-validated predictors of risk including the Meta-Analysis Global Group in Chronic Heart Failure risk score and ischemic cause. Methods: We prospectively followed 410 patients with chronic heart failure with reduced ejection fraction (61±13 years, left ventricular (LV) ejection fraction 24±7%) who underwent a clinical cMR to assess the prognostic value of PTT for a primary endpoint of overall mortality and secondary composite endpoint of cardiovascular death and heart failure hospitalization. Normal reference values of PTT were evaluated in a population of 40 asymptomatic volunteers free of cardiovascular disease. Results PTT was significantly increased in patients with heart failure with reduced ejection fraction as compared to controls (9±6 beats and 7±2 beats, respectively, P <0.001), and correlated not only with New York Heart Association class, cMR–LV and cMR–right ventricular (RV) volumes, cMR-RV and cMR-LV ejection fraction, and feature tracking global longitudinal strain, but also with cardiac output. Over 6-year median follow-up, 182 patients died and 200 reached the secondary endpoint. By multivariate Cox analysis, PTT was an independent and significant predictor of both endpoints after adjustment for Meta-Analysis Global Group in Chronic Heart Failure risk score and ischemic cause. Importantly in multivariable analysis, PTT in beats had significantly higher additional prognostic value to predict not only overall mortality (χ 2 to improve, 12.3; hazard ratio, 1.35 [95% CI, 1.16–1.58]; P <0.001) but also the secondary composite endpoints (χ 2 to improve=20.1; hazard ratio, 1.23 [95% CI, 1.21–1.60]; P <0.001) than cMR-LV ejection fraction, cMR-RV ejection fraction, LV–feature tracking global longitudinal strain, or RV–feature tracking global longitudinal strain. Importantly, PTT was independent and complementary to both pulmonary artery pressure and reduced RV ejection fraction<42% to predict overall mortality and secondary combined endpoints. Conclusions: Despite limitations in temporal resolution, PTT derived from first-pass perfusion imaging provides higher and independent prognostic information in heart failure with reduced ejection fraction than clinical and other cMR parameters, including LV and RV ejection fraction or feature tracking global longitudinal strain.

Relative Change

Background: Serial changes in high-sensitivity cardiac troponin-T (hs-cTNT) indicate progressive subclinical myocardial damage and have been associated with heart failure (HF) and death in asymptomatic older adults. Whether these associations exist in middle-age and whether serial hs-cTNT is more strongly associated with HF with reduced ejection fraction (HFREF) or HF with preserved ejection fraction (HFPEF) is poorly understood. Methods: We studied 8,838 participants of the Atherosclerosis Risk in Communities Study, initially free of coronary heart disease and HF, who had hs-cTNT measured at two time-points, 6 years apart. Using proportional hazards regression, we examined the association of absolute and relative change in hs-cTNT with incident HF hospitalization or death. Sensitivity analyses for HFPEF and HFREF were also conducted. Results: Mean age at baseline was 57 years, 57% were female and 21% were black. Over a maximum of 16 years follow-up there were 965 HF events and 1813 deaths. In adjusted models, incident detectable hs-cTNT (≥5ng/L) was associated with subsequent HF (Hazard Ratio [HR] 1.86, 95% Confidence Interval [CI] 1.53-2.25) and death (1.46 [1.28-1.68]). HRs were larger for incident hs-cTNT elevation (≥14ng/L) but similar for those with a relative increase >50% from baseline hs-cTNT (Table). In contrast, risk was lower for relative reductions >50% from baseline hs-cTNT. Temporal increases in hs-cTNT were associated with both HFREF and HFPEF in categorical analyses, however, when modeled continuously (per SD increase), absolute 6-year hs-cTNT change appeared to be more strongly associated with HFPEF hospitalization (HR 1.30 [1.06-1.60]) than with HFREF hospitalization (1.08 [0.88-1.33]). Conclusions: Absolute and relative change in hs-cTNT were independently associated with incident CHD, HF and death, even after adjustment for baseline hs-cTNT. Associations were generally consistent for both the HFREF and HFPEF phenotypes
