Background: Relatively high left ventricular ejection fraction (EF) (>65%) in women was recently associated with higher all-cause mortality over 6 years follow-up in the CONFIRM study. We sought to evaluate high EF and major adverse cardiovascular events (MACE) in the Women’s Ischemia Syndrome Evaluation (WISE) study. Methods: The WISE original cohort (enrolled 1996-2000) is a multicenter prospective study of women with suspected ischemic heart disease undergoing clinically indicated invasive coronary angiography. We investigated the relationship between high (>65%) and normal (55-65%) EF and MACE, defined as all-cause death, nonfatal myocardial infarction (MI), stroke and heart failure (HF) hospitalization using Kaplan Meier (KM) and regression analyses. Results: A total of 653 women were included (298 high and 355 normal EF). Mean age was 58±11 years and mean EF was 68±7%. There was no significant difference in MACE by EF group over a 10-year follow-up period (log rank p=0.54, Figure ). When patients were stratified by the presence of obstructive CAD, MACE rates remained similar between high and normal EF. High EF was not associated with stroke or HF but had a lower MI risk (log rank p=0.03, Table ). EF was not associated with MACE in a multivariable regression model. Conclusions: Among women presenting with evidence of ischemia, there was no significant difference in MACE between high and normal EF groups. High EF was associated with a lower risk of myocardial infarction as an individual component of MACE.

Background: BNP testing is now common though it is not clear if the test results are used to improve patient care. A high BNP may be an indicator that the left ventricular ejection fraction (LVEF) is low (<40%) such that the patient will benefit from life-prolonging therapy. Objective: To determine how often clinicians obtained a measure of LVEF (echocardiography, nuclear) following a high BNP value when the left ventricular ejection fraction (LVEF) was not known to be low (<40%). Methods and Results: We reviewed the medical records of 296 consecutive patients (inpatient or outpatient) with a BNP values of at least 200 pg/ml at a single medical center (tertiary hospital with 8 community clinics). A prior diagnosis of heart failure was made in 65%, while 42% had diabetes, 79% had hypertension, 59% had ischemic heart disease and 31% had chronic lung disease. The mean age was 73 ± 12 years, 75% were white, 10% black, 15% other and the mean BNP was 810 ± 814 pg/ml. The LVEF was known to be < 40% in 84 patients (28%, mean BNP value of 1094 ± 969 pg/ml). Of the remaining 212 patients without a known low LVEF, 161 (76%) had a prior LVEF >=40% ( mean BNP value of 673 ± 635 pg/ml), and 51 (24%) had no prior LVEF documented (mean BNP 775 ± 926 pg/ml). Following the high BNP, a measure of LVEF was obtained (including outside studies documented by the primary care provider) within 6 months in only 53% (113 of 212) of those with an LVEF not known to be low. Of those with a follow-up echocardiogram, the LVEF was <40% in 18/113 (16%) and >=40% in 95/113 (84%). There was no significant difference in mean initial BNP values between those with a follow-up LVEF <40% (872 ± 940pg/ml), >=40% (704 ± 737 pg/ml), or not done (661 ± 649 pg/ml, p=0.5). Conclusions: Follow-up measures of LVEF did not occur in almost 50% of patients with a high BNP where the information may have led to institution of life-prolonging therapy. Of those that did have a follow-up study a new diagnosis of depressesd LVEF was noted in 16%. Screening of existing BNP and LVEF data and may be an efficient strategy to identify patients that may benefit from life-prolonging therapy for heart failure.

Aim. During one-year follow-up, to assess the effect of genetic and nongenetic factors on the risk of poor outcomes in patients after myocardial infarction (MI) with high medical adherence.Material and methods. The study included 250 patients admitted to the hospital due to MI in the period from September 1, 2018 to May 1, 2019 and with a potentially high medical adherence. Twelve months after MI, patients were assessed for adherence to therapy and the effect of genetic and nongenetic factors on the patient prognosis.Results. Within 12 months after MI, 70 (28,0%) patients had a composite endpoint: all-cause death, MI, cerebral stroke, and nonelective coronary revascularization. There were following factors increasing the risk of composite endpoint: non-Q-wave MI (relative risk (RR), 2,63; 95% confidence interval (CI): 1,63-4,25 (p=0,001); left ventricular ejection fraction ≤35% — RR, 2,03; 95% CI: 1,17-3,50 (p<0,0001); CYP2C19 GA/AA genotype (RR, 1,58; 95% CI: 1,06-2,37 (p<0,00001)).Conclusion. The study results allow identifying patients with a high risk of poor outcome: patients with non-Q-wave MI, left ventricular ejection fraction ≤35%, and CYP2C19 GA/AA genotype.

Purpose of the study. Analyze the parameters of the interaction between the left ventricle and the arterial system in patients with chronic forms of coronary heart disease and to identify relationships with levels of proadrenomedullin (MR‑proADM) and N‑terminal precursor of the brain natriuretic peptide B (NT‑proBNP).Materials and methods.240 patients with chronic forms of coronary heart disease (median – 55,9 [43; 63] years) and Q‑forming myocardial infarction in the past were examined. Of these, 110 patients with myocardial infarction and preserved lef ventricular ejection fraction and 130 patients with ischemic cardiomyopathy. All patients were calculated parameters of lef ventricular‑arterial interaction and the determination in blood serum levels of MR‑proADM and NT‑proBNP.Results.In patients with ischemic cardiomyopathy, an increase in the lef ventricular‑arterial interaction index was detected (2,51 [1,18; 5,00]), which reflects a decrease in the functional abilities and efficiency of the heart. In patients with myocardial infarction and a preserved left ventricular ejection fraction, this indicator was in the range of normal values (0,78 [0,55; 1,07]), which indicates an effective cardiac work. A study of MR‑proADM and NT‑proBNP levels demonstrated an increase in both groups (1,72 [1,56; 1,98] nmol/l and 779,3 [473; 2193] pg/ml in the group of patients with ischemic cardiomyopathy; 0,89 [0,51; 1,35] nmol/l and 246 [118; 430] pg/ml in the group of patients with myocardial infarction and preserved left ventricular ejection fraction), and the correlation analysis with left ventricular‑arterial coupling interaction parameters allowed identify statistically significant connections (in the group of patients with ischemic cardiomyopathy: with the level of MR‑proADM ‑ r=0,67, p=0,006, with the level of NT‑proBNP ‑ r=0,78, p<0,001; in the group of patients with myocardial infarction and preserved left ventricular ejection fraction: with MR‑proADM level ‑ r=‑0,52, p=0,024, with NT‑proBNP level ‑ r =‑0,38, p=0,037).Conclusion.The findings suggest a pathogenetic association between the biomarkers under study and the parameters of left ventricular‑arterial coupling interaction.

Background: A significant number of heart failure (HF) patients with reduced left ventricular ejection fraction (LVEF) experience ventricular function recovery during follow-up. We studied the variables associated with LVEF recovery in patients treated with sacubitril/valsartan (SV) in clinical practice. Methods: We analyzed data from a prospective and multicenter registry including 249 HF outpatients with reduced LVEF who started SV between October 2016 and March 2017. The patients were classified into 2 groups according to LVEF at the end of follow-up (>35%: group R, or ≤35%: group NR). Results: After a mean follow-up of 7 ± 0.1 months, 62 patients (24.8%) had LVEF >35%. They were older (71.3 ± 10.8 vs. 67.5 ± 12.1 years, p = 0.025), and suffered more often from hypertension (83.9 vs. 73.8%, p = 0.096) and higher blood pressure before and after SV (both, p < 0.01). They took more often high doses of beta-blockers (30.6 vs. 27.8%, p = 0.002), with a smaller proportion undergoing cardiac resynchronization therapy (14.8 vs. 29.0%, p = 0.028) and fewer implanted cardioverter defibrillators (ICD; 32.8 vs. 67.9%, p < 0.001), this being the only predictive variable of NR in the multivariate analysis (OR 0.26, 95% CI 0.13–0.47, p < 0.0001). At the end of follow-up, the mean LVEF in group R was 41.9 ± 8.1% (vs. 26.3 ± 4.7% in group NR, p < 0.001), with an improvement compared with the initial LVEF of 14.6 ± 10.8% (vs. 0.8 ± 4.5% in group NR, p < 0.0001). Functional class improved in both groups, mainly in group R (p = 0.035), with fewer visits to the emergency department (11.5 vs. 21.6%, p = 0.07). Conclusions: In patients with LVEF ≤35% treated with SV, not carrying an ICD was independently associated with LVEF recovery, which was related to greater improvement in functional class.
