Abstract BACKGROUND Presence of heart failure (HF) is associated with poor outcome in patients with chronic kidney disease (CKD), although Left ventricular (LV) systolic function is often preserved in them. However, CKD patients may have HF symptoms with preserved LVEF. Myocardial Deformation Imaging is more accurate for detecting LV systolic dysfunction. The aim of this study was to evaluate global longitudinal (GLS) and circumferential strain (GCS) in patients with renal function impairment. METHODS Overall, 67 patients (40% men, mean age 45 ± 12 years) with CKD stage 3-4 were studied. All patients had an LV ejection fraction ≥50%. We performed echocardiography including speckle-tracking (STE) measurement of LV GLS and LV GCS and as well as assessment of diastolic function. RESULTS Despite preserved LVEF, impaired LV GLS (<18%) was observed in all patients. The mean value of GLS was 14,1 ± 1,5. This finding indicates that systolic dysfunction in CKD started from compromise LV longitudinal function. However, the GCS parameter was in the normal range – 22,7 ± 1,8. Thereby preserved LVEF was compensated by normal or slightly increase circumferential strain. Impaired diastolic function was observed in 18% of patients including 8% patients with increased left ventricle filling pressure (stage II-III). CONCLUSION The prevalence of impaired LV GLS despite preserved LVEF in patients with CKD stage 3-4 is high, which proved that renal disease is associated with early and subclinical impairment of LV systolic function. Impaired diastolic function was not so common among them. Assessment of it is not always so easy and reliable using current recommendation. Thus, STE can be recommended for early detection impairment of LV function.

Abstract Aim The aim was to evaluate left ventricular (LV) systolic function in patients with isolated mitral stenosis (MS) using 2D speckle tracking echocardiography. Methods 24 patients (39.50 ± 5.55 years, 17 females) with isolated MS (MVA: 1.35 ± 0.16 cm2) with preserved LV systolic function and sinus rhythm were compared to 12 matched healthy control subjects (36.42 ± 5.99 years, 8 females). Conventional echocardiography was performed to both groups. Longitudinal strain and Circumferential strain echocardiography were obtained. Peak systolic strain was measured from the mean strain profile for a total of 17 segments of the LV for the longitudinal strain and 16 segments for the circumferential strain. Global longitudinal (G.L.) and circumferential strain (G.C.) were calculated separately as the average of the sum of the studied segments. Results The global longitudinal strain of the cases group ranged from -11 – -17% with a mean value of -14.67 ± -1.69% and that of the control group ranged from -15 – -20% with a mean value of -17.83 ± -1.53% with a statistically significant difference between the two groups. In our study, there was a negative but non-significant correlation between LV GLSS and LA diameter (r = -0.054, p = 0.802), Echo score (r = -0.018, p = 0.933) and PASP (r = 0.021, p = 0.922) in patients group. Also, the correlation was negative but non-significant between LV GCSS and LA diameter (r = -0.142, p = 0.507), Echo score (r = -0.200, p = 0.349) and PASP (r = -0.155, p = 0.471) in patients group. Conclusion • 2D speckle tracking echocardiography can detect subclinical LV systolic dysfunction which cannot be recognized by 2D conventional echocardiography. • Isolated rheumatic MS may be associated with subclinical LV systolic dysfunction.

Chapter 6 is subdivided into three sections: global LV systolic function, regional LV systolic function, and cardiomyopathies. In Section 1, commonly used indices of global systolic function, such as fractional area change and ejection fraction, are reviewed, along with their limitations related to oesophageal imaging. The relationship between stroke volume and ejection fraction is explored. Newer techniques such as quantitative 3D imaging and strain-rate imaging are described. In Section 2, the causes of regional systolic dysfunction are reviewed, along with the different aetiologies of real and apparent segmental wall motion abnormalities. Complications of myocardial infarction such as mitral regurgitation, true and false LV aneurysms, and ventricular septal rupture are also dealt with in this section. Section 3 provides an overview of the echocardiographic findings associated with various cardiomyopathies: dilated, hypertrophic, restrictive, acute myocarditis, LV non-compaction, and Takotsubo.

Background: Left ventricular global longitudinal strain (LVGLS) can detect early phases of LV systolic dysfunction, but its application has not been studied in Ebstein anomaly. We hypothesized that LVGLS can detect early phases of LV systolic dysfunction and that patients with occult LV systolic dysfunction will have worse hemodynamics, end-organ dysfunction, and suboptimal postoperative LV reverse remodeling after tricuspid valve surgery in comparison to patients with normal LV systolic function. Methods: In this retrospective cohort study, 371 Ebstein patients that underwent tricuspid valve surgery were divided into 3 groups: normal LV systolic function (normal LVGLS and LV ejection fraction; n=244, 77%), occult LV systolic dysfunction (abnormal LVGLS with normal LV ejection fraction; n=44, 14%), and overt LV systolic dysfunction (abnormal LVGLS and LV ejection fraction; n=27, 9%). Results: Compared with the normal LV function group, the occult group had smaller LV volume and cardiac output (2.1±0.4 versus 2.9±0.6 L/min per m 2 , P <0.001), worse end-organ dysfunction (glomerular filtration rate, 78±14 versus 91±18 mL/min per 1.73 m 2 , P =0.01), and suboptimal postoperative LV reverse remodeling. Although both the occult and overt groups had a similar degree of end-organ dysfunction (glomerular filtration rate, 78±14 versus 82±16 mL/min per 1.73 m 2 , P =0.3), the occult group was less likely to be on heart failure therapy (48% versus 96%, P <0.001). Conclusions: Abnormal LVGLS was associated with suboptimal postoperative LV reverse remodeling. These data suggest that LVGLS can potentially be used for risk stratification and provides a foundation for further studies to determine whether optimal heart failure therapy or tricuspid valve intervention can improve outcomes for LV systolic dysfunction in patients with Ebstein anomaly.

Background: Renal impairment is a known predictor of mortality in both the general population and in patients with cardiac disease. The aim of this study was to evaluate factors that determine mortality in patients with chronic kidney disease (CKD) who have undergone percutaneous coronary intervention (PCI). Methods: In this study we included 293 consecutive patients with CKD who underwent PCI between 1st January 2007 and 30th September 2012. The primary outcome that we studied was all-cause mortality in a follow-up period of 12-69 months (mean 38.8 ± 21.7). Results: Age (p < 0.001), PCI indication (p = 0.035), CKD stage (p < 0.001) and left ventricular ejection fraction (p < 0.001) were significantly related to mortality. CKD stage 5 [hazard ratio (HR) = 6.39, 95% CI: 1.51-27.12) and severely impaired left ventricular function (HR = 4.04, 95% CI: 2.15-7.59) were the strongest predictors of mortality. Other factors tested (gender, hypertension, diabetes, hyperlipidaemia, established peripheral vascular disease/stroke, coronary arteries intervened, number of vessels treated, number of stents implanted and length of lesion treated) did not show any correlation with mortality. Conclusions: The mortality of patients with CKD undergoing PCI increases with age, worsening CKD stage and deteriorating left ventricular systolic function, and it is also higher in patients with acute coronary syndromes compared to those with stable coronary artery disease.

Cardiac resynchronization therapy (CRT) is highly effective for patients with left bundle branch block (LBBB), heart failure and left ventricular (LV) systolic dysfunction. Chronic right ventricular (RV) apical pacing is associated with pacing-induced cardiomyopathy and can be associated with exertional intolerance. The goal of this study was to assess the acute hemodynamic effects of His-bundle Pacing (HBP) compared to RV apical pacing in absence of LV systolic dysfunction in patients with exertional intolerance. Our patient population consisted of 5 patients with preserved LV systolic function and complete AV block. All five patients suffered from exertional intolerance in spite of preserved LV systolic function. At the time of generator change, all patients underwent implantation of a HBP lead. The QRS duration decreased from 179±13 ms with RVP to 113±6 with HBP (p < 0.001). Compared to RVP, HBP was associated with significantly longer diastolic filling time and improved septal early diastolic myocardial relaxation velocity (E’). Four of five patients noted acutely improved exertional dyspnea. In patients with AV block, exertional intolerance and preserved LV systolic function who are treated with chronic RV apical pacing, HBP may improve acute diastolic function and symptoms of exertional intolerance when compared to RV apical pacing. Randomized controlled trials are warranted to explore the effects of conduction system pacing in this unique patient population.

Abstract Funding Acknowledgements Type of funding sources: None. Diastolic function assessed my CMR feature tracking is a predictor for outcomes in patients with suspected myocarditis and preserved left ventricular ejection fraction Background Impairment of left ventricular (LV) systolic function was reported to be a valuable predictor for outcomes in patients with myocarditis. However, in patients with myocarditis and preserved LV systolic function, prediction of outcomes remains challenging. So far, minimal data exists about the prognostic role of diastolic function, as assessed by cardiac magnetic resonance imaging (CMR) in the clinical setting of suspected myocarditis. Purpose To determine the predictive value of LV diastolic function in patients with suspected myocarditis and preserved LV ejection fraction (LVEF). Methods In patients referred for CMR with clinically suspected myocarditis and LVEF≥50%, diastolic function was assessed by CMR feature tracking (FT). The primary endpoint was defined as a composite of major adverse cardiovascular events (MACE) including hospitalization for heart failure, recurrent myocarditis, sustained ventricular tachycardia and all-cause death. Results Of 381 patients included with clinically suspected myocarditis (216, 56.7% male, mean age 45.7 ± 16.4 years) late gadolinium enhancement (LGE) was present in 124 (32.4 %) of patients (mean LGE extent 4.9 ± 5.0 g). MACE occurred in 25 (6.6%) individuals at a median follow-up time of 4.5 years. In a univariate cox-regression model, radial, circumferential and longitudinal early diastolic strain rate (EDSR) and circumferential late diastolic strain rate were significantly associated with MACE. After adjustment for age, gender and extent of LGE, radial EDSR remained an independent predictor for MACE (HR = 2.26, 95% CI 1.06 to 4.8; p = 0.034). Conclusion Diastolic strain rate, as assessed by CMR-FT, can be useful in the prediction of outcomes in patients with myocarditis and preserved LVEF.

Abstract Background Patients with chronic kidney disease (CKD) are at increased risk of composite cardiovascular (CV) events and all-cause mortality. However, current aggressiveness of therapeutic strategies may minimize the course of the disease. Aim To assess the prognostic impact of optimized medical treatment in a CKD population with acute coronary syndrome (ACS). Methods 355 ACS patients admitted to a single coronary care with CKD who were discharged from hospital were included. Those with end-stage renal disease were excluded. Three groups were created based on the KDIGO classification: Group A (Stage 3A, eGFR [estimated glomerular filtration rate] 45–59mL/min/1.73 m2) N=190; Group B (Stage 3B, eGFR 30–44mL/min/1.73 m2) N=113; and Group C (Stage 3B, eGFR 15–29mL/min/1.73 m2) N=52. The primary endpoint was long-term all-cause mortality. Kaplan-Meyer survival curves and Cox regression were done. The median of follow-up was 32 (IQ 15–70) months. Results Groups were similar regarding demographics, CV risk factors, ACS type, heart failure diagnosis, left ventricular (LV) systolic function, peak troponin, multivessel disease, treatment option (PCI, CABG or OMT) and medical therapy at discharge. More advance renal failure patients had a higher prevalence of diabetes mellitus (DM), a lower haemoglobin, a higher NT-proBNP and were less likely to receive ACE inhibitors/angiotensin II antagonist at discharge. 170 patients met the primary outcome. Kaplan-Meyer curves showed decreased survival with worse renal function (Group A 68% vs Group B 57% vs Group C 37%, Log Rank P=0.006 – Figure 1). After adjustment for age, DM, haemoglobin, NT-proBNP, LV systolic function and ACE inhibitors/angiotensin II antagonist at discharge, eGFR was not associated with increased death (HR 1.00, 95% CI 0.98–1.01). In this model, only age (HR 1.04, 95% CI 1.01–1.07), haemoglobin (HR 0.86, 95% CI 0.979–0.94), Nt-proBNP (HR 1.00, 95% CI 1.00–1.00) and impaired LV function (LV ejection fraction 40–49%: HR 2.95, 95% CI 1.89–4.81; LV ejection fraction &lt;40%: HR 2.15, 95% CI 1.44–3.21) remained associated with the outcome. Conclusion The worse outcome attributed to CKD after an ACS seems to be related not the eGFR itself but to associated comorbidities such as age, anaemia, fluid overload and impaired LV function. The fact that some of these comorbidities may be altered by intensive therapy indicates that CKD patients should also be candidates to optimized medical treatment.

Abstract Background The cardiovascular mortality of patients with chronic kidney disease (CKD) is 2–10 times higher than in the average population. Purpose To estimate the prevalence of abnormal cardiac function or structure across the stages CKD 1 to 5nonD. Method Prospective cohort study. Patients with CKD stage 1 to 5 not on dialysis, aged 30 to 75 (n=875) and age-/sex-matched controls (n=173) were enrolled consecutively. All participants underwent a health questionnaire, ECG, morphometric and blood pressure measurements. Blood and urine were analyzed. Echocardiography was performed. Left ventricle (LV) hypertrophy, dilatation, diastolic and systolic dysfunction were defined according to current ESC guidelines. Results 63% of participants were men. Mean age was 58 years (SD 12.6 years). Mean eGFR was 46.7 mL/min/1,73 m (SD 25.8) for patients and 82.3 mL/min/1,73 m (SD 13.4) for controls. The prevalence of elevated blood pressure at physical exam was 89% in patients vs. 53% in controls. Patients were more often smokers and obese. Left ventricular mass index (LVMI) was slightly, albeit insignificantly elevated at CKD stages 1 & 2 vs. in kontrols: 3.1 g/m2, CI: −0.4 to 6.75, p-value 0.08. There was no significant difference in LV-dilatation between patients and controls. Decreasing diastolic and systolic function was observed at CKD stage 3a and later: LVEF decreased 0.95% (CI: −1.5 to −0.2), GLS increased 0.5 (CI: 0.3 to 0.8), and OR for diastolic dysfunction increased 3.2 (CI 1.4 to 7.3) pr. increment CKD stage group. Conclusion In accordance to previous studies, we observe in the CPHCKD cohort study signs of early increase of LVMI in patients with CKD stage 1 & 2. Significant decline in systolic and diastolic cardiac function is apparent already at stage 3 CKD. Figure 1.

Abstract Background Central apneas (CA) and obstructive apneas (OA) are highly prevalent in heart failure (HF) both with reduced and preserved systolic function. However, a comprehensive evaluation of apnea prevalence across HF according to ejection fraction (i.e HF with patients with reduced, mid-range and preserved ejection fraction- HFrEf, HFmrEF and HFpEF, respectively) throughout the 24 hours has never been done before. Materials and methods 700 HF patients were prospectively enrolled and then divided according to left ventricular EF (408 HFrEF, 117 HFmrEF, 175 HFpEF). All patients underwent a thorough evaluation including: 2D echocardiography; 24-h Holter-ECG monitoring; cardiopulmonary exercise testing; neuro-hormonal assessment and 24-h cardiorespiratory monitoring. Results In the whole population, prevalence of normal breathing (NB), CA and OA at daytime was 40%, 51%, and 9%, respectively, while at nighttime 15%, 55%, and 30%, respectively. When stratified according to left ventricular EF, CA prevalence decreased from HFrEF to HFmrEF and HFpEF: (daytime CA: 57% vs. 43% vs. 42%, respectively, p=0.001; nighttime CA: 66% vs. 48% vs. 34%, respectively, p&lt;0.0001), while OA prevalence increased (daytime OA: 5% vs. 8% vs. 18%, respectively, p&lt;0.0001; nighttime OA: 20 vs. 29 vs. 53%, respectively, p&lt;0.0001). When assessing moderte-severe apneas, defined with an apnea/hypopnea index &gt;15 events/hour, prevalence of CA was again higher in HFrEF than HFmrEF and HFpEF both at daytime (daytime moderate-severe CA: 28% vs. 19% and 23%, respectively, p&lt;0.05) and at nighttime (nighttime moderate-severe CA: 50% vs. 39% and 28%, respectively, p&lt;0.05). Conversely, moderate-severe OA decreased from HFrEF to HFmrEF to HFpEF both at daytime (daytime moderate-severe OA: 1% vs. 3% and 8%, respectively, p&lt;0.05) and nighttime (noghttime moderate-severe OA: 10% vs. 11% and 30%, respectively, p&lt;0.05). Conclusions Daytime and nighttime apneas, both central and obstructive in nature, are highly prevalent in HF regardless of EF. Across the whole spectrum of HF, CA prevalence increases and OA decreases as left ventricular systolic dysfunction progresses, both during daytime and nighttime.
