Genetic background of different mouse strains determines their susceptibility to disease. We have previously shown that Balb/CJ and C57BL/6J mice develop cardiac hypertrophy to the same degree when treated with a combination of angiotensin II and high-salt diet (ANG II+Salt), but only Balb/CJ show impaired cardiac function associated with edema development and substantial mortality. We hypothesized that the different response to ANG II+Salt is due to the different genetic backgrounds of Balb/CJ and C57BL/6J. To address this we performed quantitative trait locus (QTL) mapping of second filial generation (F2) of mice derived from a backcross between Balb/CJ and first filial generation (F1) of mice. Cardiac function was measured with echocardiography, glomerular filtration rate using FITC-inulin clearance, fluid and electrolyte balance in metabolic cages, and blood pressure with tail-cuff at baseline and on the fourth day of treatment with ANG II+Salt. A total of nine QTLs were found to be linked to different phenotypes in ANG II+Salt-treated F2 mice. A QTL on chromosome 3 was linked to cardiac output, and a QTL on chromosome 12 was linked to isovolumic relaxation time. QTLs on chromosome 2 and 3 were linked to urine excretion and sodium excretion. Eight genes located at the different QTLs contained coding nonsynonymous SNPs published in the mouse genome database that differ between Balb/CJ and C57BL/6J. In conclusion, ANG II+Salt-induced acute decompensation in Balb/CJ is genetically linked to several QTLs, indicating a multifaceted phenotype. The present study identified potential candidate genes that may represent important pathways in acute decompensated heart failure.

Background: Irreversible worsening of cardiac function is an adverse event associated with significant morbidity among patients with acute decompensated heart failure (ADHF). We aimed to develop a parsimonious model which is simple to use in clinical settings for the prediction of the risk of irreversible worsening of cardiac function.Methods: A total of 871 ADHF patients were enrolled in this study. Data for each patient were collected from the medical records. Irreversible worsening of cardiac function included cardiac death within 30-days of patient hospitalization, implantation of a left ventricular assistance device, or emergency heart transplantation. We performed LASSO regression for variable selection to derive a multivariable logistic regression model. Five candidate predictors were selected to derive the final prediction model. The prediction model was verified using C-statistics, calibration curve, and decision curve.Results: Irreversible worsening of cardiac function occurred in 7.8% of the patients. Advanced age, NYHA class, high blood urea nitrogen, hypoalbuminemia, and vasopressor use were its strongest predictors. The prediction model showed good discrimination C-statistic value, 0.866 (95% CI, 0.817–0.907), which indicated good identical calibration and clinical efficacy.Conclusion: In this study, we developed a prediction model and nomogram to estimate the risk of irreversible worsening of cardiac function among ADHF patients. The findings may provide a reference for clinical physicians for detection of irreversible worsening of cardiac function and enable its prompt management.

Abstract Background Timely use of Sacubitril/Valsartan has the potential to significantly improve cardiac function and dramatically reduce secondary mitral regurgitation (MR) severity even in patients presenting with acute decompensated heart failure (HF), not only in compensated chronic HF patients. The outstanding impact of echocardiography is obvious in monitoring improvement of cardiac function and MR severity in patients with HF with reduced ejection fraction (HFrEF). Case summary We report a relevant case of an elderly patient who presented with acute decompensated HF and severe MR. He was symptomatic despite being on maximally tolerated doses of ACEI, beta-blockers, and diuretics. Left ventricular ejection fraction (LVEF) improved from 15% to 35% 2 weeks following initiation of Sacubitril/Valsartan during second HF hospitalization. There was a dramatic improvement of patient’s symptoms from New York Heart Association (NYHA) Class IV to NYHA I. N-terminal pro B-type natriuretic peptide reduced from 9000 pg/mL to 800 pg/mL. Coronary angiography depicted three-vessel coronary artery disease. The patient was advised to undergo coronary artery bypass graft surgery with mitral valve repair, then followed by implantation of a cardiac resynchronization therapy-defibrillator device (CRT-D) if no LV function improvement is observed after revascularization. The electrocardiogram showed Q waves in inferior leads with QRSd ≥ 125 ms, hence a good candidate for CRT. Following an elective percutaneous coronary intervention, LVEF further improved to 50%. The patient became asymptomatic with preserved LVEF on follow-up for 18 months later. Discussion This case report documents the swift echocardiographic and symptom improvement in a decompensated end-stage HF patient when Sacubitril/Valsartan initiated during acute setting.

Background: Tachycardia worsens cardiac performance in acute decompensated heart failure (ADHF). We investigated whether heart rate (HR) optimization by landiolol, an ultra-short-acting β1-selective blocker, in combination with milrinone improved cardiac function in patients with ADHF and rapid atrial fibrillation (AF). Methods and Results: We enrolled9 ADHF patients (New York Heart Association classification IV; HR, 138 ± 18 bpm; left ventricular [LV] ejection fraction, 28 ± 8%; cardiac index [CI], 2.1 ± 0.3 L/min–1/m–2; pulmonary capillary wedge pressure [PCWP], 24 ± 3 mm Hg), whose HRs could not be reduced using standard treatments, including diuretics, vasodilators, and milrinone. Landiolol (1.5–6.0 µg/kg–1/min–1, intravenous) was added to milrinone treatment to study its effect on hemodynamics. The addition of landiolol (1.5 µg/kg–1/min–1) significantly reduced HR by 11% without changing systolic blood pressure (BP) and resulted in a significant decrease in PCWP and a significant increase in stroke volume index (SVI), suggesting that HR reduction restores incomplete LV relaxation. Administration of more than 3.0 µg/kg–1/min–1 of landiolol decreased BP, CI, and SVI. Conclusion: The addition of landiolol at doses of <3.0 µg/kg/min to milrinone improved cardiac function in decompensated chronic heart failure with rapid atrial fibrillation by selectively reducing HR.

Acute heart failure – the rapid onset of, or change in, signs and/or symptoms of heart failure requiring urgent treatment – is a serious clinical syndrome, associated with high mortality and healthcare costs. History, physical examination and early 2D and Doppler echocardiography are crucial to the proper assessment of patients, and will help determine the appropriate monitoring and management strategy. Most patients are elderly and have considerable co-morbidity. Clinical assessment is key to monitoring progress, but a number of clinical techniques – including simple Doppler and echocardiographic tools, pulse contour analysis and impedance cardiography – can help assess the response to therapy. A pulmonary artery catheter is not a routine monitoring tool, but can be very useful in patients with complex physiology, in those who fail to respond to therapy as would be anticipated, or in those being considered for mechanical intervention. As yet, the serial measurement of plasma natriuretic peptides is of limited value, but it does have a role in diagnosis and prognostication. Increasingly, the remote monitoring of physiological variables by completely implanted devices is possible, but the place of such technology in clinical practice is yet to be clearly established.
