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 < 0.05), LV mass index (122.4 ± 38.9 vs 107.5 ± 26.4 g/m², p < 0.05), left atrial volume index (31.7 ± 9.2 vs 27.6 ± 9.4 ml/m², p < 0.05), LVEF (45.7 ± 13.5 vs 52.9 ± 9.2 %, p < 0.05), s’ (5.1 ± 1.6 vs 7.1 ± 1.7 cm/sec, p < 0.001), e’ (4.8 ± 1.3 vs 6.0 ± 1.9 cm/sec, p < 0.05), E/e’ (16.4 ± 6.6 vs 12.5 ± 4.9, p < 0.05), E/(e’ x s’) (3.78 ± 2.52 vs 1.94 ± 1.08, p < 0.001), and serum B-type natriuretic peptide (334.7 ± 420.1 vs 113.8 ± 177.2 pg/ml, p < 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’) <2.35 had significantly better prognosis than the rest (p < 0.0001, Log-rank; Figure)Conclusion: E/(e’ x s’) could be a useful echo marker to predict cardiac events in ACS patients.

Abstract   Left ventricular (LV) global function index (LVGFI) is a MRI marker of left ventricular remodeling. LVGFI has high predictive significance in young healthy individuals. The aim of the study was to assess prognostic significance in patients with acute coronary syndrome (ACS). We include into this analysis 2169 patients with ACS (1340 (61.8%) men and 829 (38.2%) women), mean age 64.08±12.601 years. All patients were observed in 2 Russian multicenter observational studies: ORACLE I (ObseRvation after Acute Coronary syndrome for deveLopment of trEatment options) (2004–2007 years) and ORACLE II (NCT04068909) (2014–2019 years). 1886 (87.0%) pts had arterial hypertension, 1539 (71.0%) – history of coronary artery disease, 647 (29.8%) – history of myocardial infarction, 444 (20.5%) - diabetes mellitus. Duration of the follow-up was 1 years after the hospital discharge. Cases of death from any cause, coronary deaths, repeated coronary events (fatal and non-fatal) were recorded. An echocardiographic study was conducted 5–7 days from the time of hospitalization. The LVGFI was defined as LV stroke volume/LV global volume × 100, where LV global volume was the sum of the LV mean cavity volume ((LV end-diastolic volume + LV end-systolic volume)/2) and myocardial volume (LV mass/density). During the follow-up, 193 deaths were recorded (8.9%), 122 deaths (5.6%) were coronary. In total, repeated coronary events were recorded in 253 (11.7%) patients. Mean LVGFI was 22.64±8.121%. Patients who died during the follow-up were older (73.03±10.936 years and 63.15±12.429 years, p=0.001), had a higher blood glucose level at the admission to the hospital (8.12±3.887 mmol/L and 7.17±3.355 mmol/L, p=0.041), serum creatinine (110.86±53.954 μmol/L and 99.25±30.273 μmol/L, p=0.007), maximum systolic blood pressure (196.3±25.17 mm Hg and 190.3±27.83 mm Hg, p=0.042). Those who died had a lower LVGFI value (19.75±6.77% and 23.01±8.243%, p<0.001). Myocardial mass index, ejection fraction and other left ventricular parameters did not significantly differ between died and alive patients. Among the patients who died, there were higher rate of women, pts with a history of myocardial infarction, heart failure, diabetes. In a multivariate analysis, diabetes mellitus OR1.67 95% CI [1.12–2.51] p=0.012, history of heart failure (1.78 [1.2.-2.59], p=0.003), a history of myocardial infarction (1.47 [1.05–2.05], p=0024), age (1.06 [1.05–1.08], p=0.001) and LVGFI <22% (1.53 [1.08–2.17], p=0.015) were independent predictors of death from any cause. The LVGFI was also independently associated with the risk of coronary death, but not with the risk of all recurring coronary events. Thus, LVGFI may be useful the marker to assess risk in patients who have experienced an ACS episode. Funding Acknowledgement Type of funding source: None

Abstract Background: carbohydrate antigen 125 (CA125) is an increasingly promising biomarker of heart failure (HF), but its prognostic value in female patients with acute coronary syndrome (ACS) is unclear. We aimed to determine the short-term and mid-term prognostic value of CA125 serum levels in female ACS patients.Methods: A total of 131 consecutive female patients with ACS were retrospective enrolled. Their CA125 levels, B-type natriuretic peptide (BNP) levels and biochemical parameters were measured, and echocardiography was performed at admission. All-cause mortality during hospitalization and two-year follow-up was investigated for the prognosis.Results: The median value of CA125 serum level in the entire ACS patients was 13.85 U/mL. Patients in Killip Ⅲ had the highest values of CA125 level, followed by Killip Ⅱ and then Killip Ⅰ (p < 0.05). However, no statical difference was observed between Killip Ⅳ and Ⅰ-Ⅲ groups respectively (P > 0.05). The CA125 serum levels showed weak positive correlation with left ventricular end-diastolic diameter (LVEDD) (r = 0.3, P < 0.01) and a weak negative correlation with left ventricular ejection fraction (LVEF) (r = –0.23, p < 0.01). A receive operating characteristic (ROC) curve analysis showed that the AUC of CA125 in predicting acute heart failure (AHF) in ACS patients during hospitalization was 0.912, exhibiting higher sensitivity and specificity than BNP (0.846). The optimal cut-off value for CA125 in predicting AHF was 16.4 U/mL with a sensitivity of 0.916 and specificity of 0.893. The Kaplan-Meier survival analysis demonstrated that patients with high values of CA125 level had a poor overall survival than those with low values of CA125 level (log-rank, p < 0.001), whether during hospitalization or mid-term follow-up. Conclusion: Elevated CA125 level can be used to predict AHF in female ACS patients. Patients with elevated CA125 levels had higher mortality in short-term and mid-term than those with low CA125 levels.

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.

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 The new European Society of Cardiology guideline for ST-segment elevation myocardial infarction recommends that left and right bundle branch block should be considered equal for recommending urgent angiography in patients with suspected myocardial infarction. This consideration is not taken into account in the management of patients with coronary syndrome without ST elevation (NSTEMI). We evaluate the evolution of patients with acute coronary syndrome and long-term bundle branch block. Patients and methods We included 8771 patients admitted to two tertiary hospitals between 2003 and 2017 with an acute coronary syndrome, 5673 NSTEMI (64.3%) and 3098 STEMI (35.7%). All patients had an ECG recorded immediately upon admission. Patients were classified as having right bundle branch block (RBBB), left bundle branch block (LBBB). Long-term follow-up was performed (median 55 months) to assess mortality. Results A total of 8771 patients were included with a mean age of 66.1 years, 72.5% males, 4.1% (362) with LBBB and 5% (440) with RBBB. Patients with BBB were older, with more previous history of myocardial infarction and coronary revascularization and higher prevalence of cardiovascular risk factors. Medical treatment was similar but they were less often submitted to angioplasty. During the acute phase, patients with RBBB and LBBB presented a higher rate of heart failure than those without branch block (4.8% vs 9.1% vs 3.5%, p=0.0001); higher mortality (8.4% vs 10.5% vs 3.0%, p=0.0001); higher stroke rate (2.5% vs 1.4% vs 0.8%, p=0.001); higher rate of renal failure (8.2% vs 9.7% vs 3.9%, p=0.0001) and higher rate of reinfarction (3.0% vs 4.1% vs 1.7%, p=0.001). Patients who had a RBBB or an LBBB had a worse prognosis throughout the follow-up. Heart failure was present in 17.7% of the group with RBBB, 29.6% of LBBB and 11% in the group without branch block (p=0.0001). Mortality during follow-up was 31% in RBBB, 40.6% in LBBB and 18.7% without branch block (p=0.0001). In multivariate analysis of Cox, both RBBB (HR 1.55, 95% CI 1.23–1.98, p=0.0001) and LBBB (HR 1.48, 95% CI 1.22–1.53, p=0.001) were an independent predictors of all-cause mortality (adjustment for GRACE score, gender, treatment with betablockers, angiotensin conversor enzym inhibitors, statin and coronary revascularization). Cox regression model multivariate Conclusions The presence of RBBB or LBBB in the ECG of patients with an ACS is associated with a worse prognosis both during the hospital phase and in the long term. In addition, both bundle branch blocks are independent predictors of long-term mortality in patients with ACS.

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.

Acute Coronary syndrome (ACS) is the most common cause of admission to the coronary care unit with highest risk of death and adverse outcomes. ACS accounts for 60–70% of all admissions in the hospital. Patients with ACS encompass a heterogeneous group that varies widely regarding severity of the underlying coronary artery disease, prognosis and response to treatment. Patients with the highest risk of subsequent events usually have the largest benefit of an intensified pharmacological treatment and early mechanical intervention. The prognosis for low-risk patients, on the other hand, is often difficult to improve further and these patients usually benefit more from a conservative management with a lower risk of side effects. Therefore, risk stratification is essential and should be initiated early and updated continuously throughout the hospital stay. Early risk stratification is usually performed by the use of clinical background factors, clinical presentation, electrocardiography and biochemical markers of myocardial damage. Levels of natriuretic peptides have been shown to reflect cardiac performance. The aim of this study was to review elaborately on B type Natriuretic Peptide (BNP) and its prognostic value in patient with ACS. This review focuses on the emerging role of these peptides in the early risk stratification of ACS patients. Elevation of BNP levels in acute MI and UA is predictive of a greater risk of death, post infarction heart failure, or  reinfarction. Post infarction studies demonstrate that elevated plasma BNP levels are associated with larger infarct size, increased probability of ventricular remodeling, lower ejection fraction, higher risk of heart failure, and increased mortality. This cardiac marker is a potent predictor of mortality in patients with all forms ACS. BNP measurements serve as an index of severity of the ischemic injury, as well as the degree of impairment in left ventricular function.DOI: http://dx.doi.org/10.3329/cmoshmcj.v13i2.21079
