ABSTRACT

BACKGROUND: Sacubitril/valsartan plays a key role in improving left ventricular remodeling and prognosis in patients with heart failure with a reduced ejection fraction (HFrEF). Moreover, some data support its role in preserving renal function. In order to better clarify the effects of sacubitril/valsartan in cardiorenal syndrome, this study evaluated its effects on the renal resistance index (RRI). METHODS: A group of patients with HFrEF was enrolled. The RRI was assessed with renal echo-color Doppler at enrollment and again after at least six months of sacubitril/valsartan treatment. In a subgroup of patients, the RRI was also evaluated at least six months before enrollment. The variations in echocardiographic parameters reflecting the left and right ventricular function, as well as creatinine and the estimated glomerular filtration rate, were also evaluated. RESULTS: After treatment with sacubitril/valsartan, significant improvements in the left ventricular ejection fraction, and a decrease in the left atrial and ventricular volumes were observed. The RRI also showed a significant decrease. No relationship was found between the improvements in the parameters reflecting cardiac function and changes in the RRI. CONCLUSIONS: Treatment with sacubitril/valsartan is associated with improvements in both left ventricular function and renal perfusion, through decreasing the renal resistance. These data help to clarify the effects of the drug on cardiorenal syndrome progression.

ABSTRACT

The impact of coronary artery disease (CAD) on all-cause mortality and overall disabilities is well-established. Percutaneous and/or surgical coronary revascularization procedures dramatically reduced the occurrence of adverse cardiovascular events in patients suffering from atherosclerosis. Specifically, guidelines from the European Society of Cardiology on the management of myocardial revascularization promoted coronary artery by-pass graft (CABG) intervention in patients with specific alterations in the coronary tree due to the higher beneficial effects of this procedure as compared to the percutaneous one. The left internal mammary artery (LIMA) is one of the best-performing vessels in CABG procedures due to its location and its own structural characteristics. Nevertheless, the non-invasive assessment of its patency is challenging. Doppler ultrasonography (DU) might perform as a reliable technique for the non-invasive evaluation of the patency of LIMA. Data from the literature revealed that DU may detect severe (>70%) stenosis of the LIMA graft. In this case, pulsed-wave Doppler might show peak diastolic velocity/peak systolic velocity < 0.5 and diastolic fraction < 50%. A stress test might also be adopted for the evaluation of patency of LIMA through DU. The aim of this narrative review is to evaluate the impact of DU on the evaluation of the patency of LIMA graft in patients who undergo follow-up after CABG intervention.

ABSTRACT

AIMS: Sodium-glucose co-transporter-2 inhibitors (SGLT2i) have been shown to have a relevant role in the prevention of hospitalizations for heart failure and improvement in the life expectancy of patients with diabetes and outpatients with chronic heart failure (CHF) with reduced left ventricular ejection fraction, independently from the presence of type 2 diabetes mellitus (T2DM). The aim of our study was to evaluate in a real-world population the number of outpatients with CHF who meet the enrolment criteria of the main randomized controlled trials (RCT) published in the last 5 years and consequently identify the percentage of patients who could potential benefit from SGLT2i therapy. METHODS AND RESULTS: We retrospectively evaluated all consecutive outpatients referred for CHF. The diagnosis of T2DM was according to the latest European Society of Cardiology Guidelines. Clinical characteristics considered for the enrolment in the RCTs were recorded. We enrolled 515 patients, 384 (75%) of whom had a left ventricular ejection fraction (LVEF) ≤ 40%, 82 (16%) had pre-diabetes, and 187 (36%) had diabetes. Most of the patients with LVEF ≤ 40% met the criteria for the DAPA-HF trial (65%), and this percentage was even higher if the serum level of N-terminal pro-brain natriuretic peptide was not considered. A high percentage of patients with diabetes and LVEF > 40% met the criteria for the DECLARE (39%), CANVAS (47%), and EMPA-REG (30%) trials. Patients meeting the enrolment criteria of RCTs evaluating SGLT2i were also characterized by a high risk of heart failure events during follow-up. CONCLUSIONS: In spite of a low number of patients actually treated with SGLT2i, we observed that a high prevalence of patients with CHF met the clinical characteristics of RCTs that have demonstrated a beneficial effect of SGLT2i.

ABSTRACT

BACKGROUND: Hypothyroidism is a frequently observed comorbidity in patients with chronic heart failure (CHF), possibly giving rise to unfavorable outcomes. AIM: The aim of the study was to evaluate the impact of TSH changes over time on cardiac function and prognosis of outpatients with CHF. METHODS: Patients underwent clinical, electrocardiographic, and echocardiographic evaluations at baseline and after 12 months. Moreover, blood chemistry tests were performed to evaluate renal function, cardiac biomarkers, fT3, fT4, and TSH levels. Based on TSH serum levels, patients were retrospectively classified into four categories: Group 1, patients with improved thyroid function at one-year follow up vs. baseline; Group 2, patients with stable and mildly high TSH values (3.74 - 10 mUI/L); Group 3, patients with worsening thyroid function; Euthyroid patients Group, TSH levels within the normal range of reference at baseline as well as at 12 months follow-up. We considered as end-points: one-year changes of laboratory and echocardiographic parameters; hospitalizations due to worsening of HF (acute decompensated heart failure - ADHF); death for all causes. RESULTS: Among 257 patients, 174 (67.7%) were euthyroid at baseline and after 12 months. Group 1 patients (n. 22, 8.6%) showed a significant improvement in systolic and diastolic function, filling pressures, NT-proBNP and Galectin-3. Group 2 patients (n. 34, 13.2%) did not exhibit significant modifications in studied parameters. Group 3 patients (n. 27, 10.5%) showed worsening of diastolic function and NT-proBNP and a greater risk of ADHF (HR: 2.12; 95%CI: 1.20-3.74; p: 0.009) and death (HR: 4.05; 95%CI: 2.01-8.15; p<0.001). CONCLUSION: In patients with CHF, changes in thyroid function over time influenced echocardiographic parameters and biomarkers reflecting modifications of cardiac function and prognosis, thus suggesting the clinical relevance of thyroid deficiency screening and correction.

ABSTRACT

The aim of this study is to identify the best predictors of mortality among clinical, biochemical and advanced echocardiographic parameters in acute heart failure (AHF) patients admitted to coronary care unit (CCU). AHF is a clinical condition characterized by high mortality and morbidity. Several studies have investigated the potential prognostic factors that could help the risk assessment of cardiovascular events in HF patients, but at the moment it has not been found a complete prognostic score (including clinical, laboratory and echocardiographic parameters), univocally used for AHF patients. Patients (n = 118) admitted to CCU due to AHF de novo or to an exacerbation of chronic heart failure were enrolled. For each patient, clinical and biochemical parameters were reported as well as the echocardiographic data, including speckle tracking echocardiography analysis. These indexes were then related to intra- and extrahospital mortality. At the end of the follow-up period, the study population was divided into two groups, defined as 'survivors' and 'non-survivors'. From statistical analysis, C-reactive protein (CRP) (AUC = 0.75), haemoglobin (AUC = 0.71), creatinine clearance (AUC = 0.74), left atrial strain (AUC = 0.73) and freewall right ventricular strain (AUC = 0.76) showed the strongest association with shortterm mortality and they represented the items of the proposed risk score, whose cut-off of 3 points is able to discriminate patients at higher risk of mortality. AHF represents one of the major challenges in CCU. The use of a combined biochemical and advanced echocardiographic score, assessed at admission, could help to better predict mortality risk, in addition to commonly used indexes.

ABSTRACT

There is growing attention for the study of the right ventricle in cardiovascular disease and in particular in heart failure. In this clinical setting, right ventricle dysfunction is a significant marker of poor prognosis, regardless of the degree of left ventricular dysfunction. Novel echocardiographic methods allow for obtaining a more complete evaluation of the right ventricle anatomy and function as well as of the related abnormalities in filling pressures. Specific and effective therapies for the right ventricle dysfunction are still not well defined and this represents the most difficult and important challenge. This article focuses on available diagnostic techniques for studying right ventricle dysfunction as well as on the therapies for right ventricle dysfunction.

ABSTRACT

BACKGROUND: Hyperkalemia is one of the most frequent side effects related to renin-angiotensin-aldosterone system (RAAS) inhibition, and can influence optimization of heart failure (HF) therapy. AIM: To evaluate the occurrence of hyperkalemia in a series of outpatients with chronic HF and its relationship with RAAS inhibitor therapy. METHOD: We evaluated consecutive outpatients with HF and a reduced left ventricular ejection fraction. The incidence of hyperkalemia and consequent changes in RAAS inhibitor therapy were evaluated for each patient. RESULTS: A history of hyperkalemia or at least 1 episode of hyperkalemia during follow-up was observed in 104 of 351 patients. Hyperkalemia mainly influenced mineralocorticoid receptor antagonist (MRA) therapy and, among patients with hyperkalemia, not taking MRA was associated with a greater risk of death on univariate analysis (HR = 6.39; 95% CI 2.76-14.79, p < 0.001) and multivariate analysis (HR = 5.24; 95% CI 1.87-14.72, p = 0.002) after correction for age, ischemic cardiomyopathy, diabetes, systolic arterial pressure, New York Heart Association class 3, left ventricular ejection fraction, presence of hyponatremia, glomerular filtration rate calculated by the EPI formula, and presence of N-terminal pro-B-type natriuretic peptide >1,000 pg/mL. CONCLUSION: The occurrence of hyperkalemia is common among outpatients with HF and it is the main cause of MRA withdrawal, which is associated with a worse prognosis. In this setting, the possibility of managing hyperkalemia using new classes of drugs could allow continuation of MRA therapy.

ABSTRACT

Some forms of early ECG repolarization QRS pattern (ERp) with J-point elevation of 0.1 mV in two contiguous inferior and/or lateral leads with or without ST-elevation are potentially associated with a higher arrhythmic risk in adults. We assessed the prevalence of ERp among non-professional adolescent athletes and correlated it with age, sex, ethnicity, and structural and electric cardiac parameters. We retrospectively analyzed 414 ECGs obtained from young athletes referred to our center from 2006 to 2017. We found ERp in 22% of cases. In the ERp group, we found a greater percentage of black athletes, a higher systolic blood pressure, and lower heart rate (HR) compared with the group without ERp. This pattern was less frequent in female athletes. In athletes with ERp, the occurrence of ventricular ectopic beats was less frequent and QRS-duration was shorter. They also exhibited greater (a) ECG-based left ventricular hypertrophy (LVH), (b) left ventricular mass, and (c) relative wall thickness (RWT), suggesting a tendency to concentric geometry. At logistic regression analysis, we found that HR (OR 0.98 [0.96-0.99] P = .013), QRS-duration (OR 0.96 [0.94-0.99], P = .003), LVH (OR 1.09 [1.05-1.12], P < .001), and RWT (OR 1.08 [1.01-1.16] P = .032) were significant predictors of ERp incidence. ERp is quite common in adolescent athletes and correlates with concentric LV remodeling. Specific clinical and ECG-findings related to training such as lower HR, LVH, and QRS-duration are also predictors of ERp. In adolescent non-professional athletes, ERp is a benign finding associated with some structural and electric cardiac modifications induced by training.

ABSTRACT

Aim: The aim of the study was to evaluate the association between Gal-3 serum levels and the progression of renal dysfunction in chronic heart failure outpatients. Methods & results: This prospective study of 260 chronic heart failure patients showed that Gal-3 was associated with 1-year worsening of renal function both in univariate (odds ratio: 1.12; 95% CI: 1.06-1.18; p < 0.001) and in forward stepwise multivariate (odds ratio: 1.09; 95% CI: 1.03-1.15; p = 0.004) logistic regression analyses. Moreover, high Gal-3 levels at baseline were associated with a progressive decline in the estimated glomerular filtration rate. Conclusion: Gal-3 is a biomarker associated with the progression of renal function decline thus further supporting its possible usefulness in predicting cardiorenal syndrome progression.

ABSTRACT

Atrial masses are rare and more often localized in the right atrium. They are usually detected incidentally, and the leading causes are tumors, thrombi, or infective vegetations. However, normal structures and artifacts ("pseudomasses") should also be considered in differential diagnosis, especially after cardiac and/or aortic surgery. We present a case of an unusual left atrial image observed on transthoracic echocardiography in an 83-year-old woman after an intervention of open-chest ascending aorta replacement and myocardial revascularization.

ABSTRACT

Kidney disease is commonly found in heart failure (HF) patients. They share many risk factors and common pathophysiological pathways which often lead to mutual dysfunction. Both haemodynamic and non-haemodynamic mechanisms are involved in the development of renal impairment in heart failure patients. Moreover, the presence of a chronic kidney disease is a significant independent predictor of worse outcome in chronic as well as in acute decompensated HF. As a consequence, an accurate evaluation of renal function plays a key role in the management of HF patients. Serum creatinine levels and glomerular filtration rate (GFR) estimates are the corner stones of renal function evaluation in clinical practice. However, to overcome their limits, several emerging glomerular and tubular biomarkers have been proposed over the last years. Alongside the renal biomarkers, imaging techniques could complement the laboratory data exploring different pathophysiological pathways. In particular, Doppler evaluation of renal circulation is a highly feasible technique that can effectively identify HF patients prone to develop renal dysfunction and with a worse outcome. Finally, some classes of drugs currently used in heart failure treatment can affect renal function and their use can be influenced by the presence of chronic kidney disease.

ABSTRACT

Among comorbidity in chronic heart failure (CHF), dysthyroidism represents a relevant problem especially in the ageing CHF patients worldwide. Thyroid greatly affects many cardiovascular activities and its dysfunction may worsen a CHF condition. In particular, hypothyroidism has a relative high prevalence in patients with heart failure and it plays a key role in influencing CHF onset, progression and prognosis. Hyperthyroidism, is less frequent in this clinical context but it necessitates of immediate treatment because of its negative effects on cardiovascular balance. Also, it must be considered that dysthyroism may also be iatrogenic and the main responsible drug is Amiodarone.Based on the best available evidence and our cumulative clinical experience, this manuscript analyzes the prevalence, the pathophysiology and the prognostic impact of thyroid disorders in chronic heart failure.

ABSTRACT

Galectin-3 and ST2 are emerging biomarkers involved in myocardial fibrosis. We evaluate the relevance of a multiparametric biomarker approach based on increased serum levels of NT-proBNP, galectin-3, and ST2 in stratifying the prognosis of chronic heart failure (CHF) outpatients. In 315 CHF outpatients in stable clinical condition clinical and echocardiographic evaluations were performed. Routine chemistry and serum levels of NT-proBNP, galectin-3, and ST2 were also assessed. During a 12 month follow-up, cardiovascular death, and/or heart failure (HF) occurred in 64 patients. The presence of NT-proBNP, galectin-3, and ST2 were higher than the recommended cutoffs and were all associated with events at univariate Cox regression analysis, as well as in a multivariate analysis including the three biomarkers. When a score based on the number of biomarkers above the recommended cut-offs was used (in a range of 0-3), it was associated with events both with respect to the univariate (HR 2.96, 95% CI 2.21-3.95, p < 0.001, C-index 0.78) and the multivariate (HR 1.52, 95% CI 1.06-2.17, p: 0.023, C-index 0.87) analyses, after correction for the variables of a reference model. Our results suggest that an easy prognostic approach based on the combination of three biomarkers, although with partially-overlapping pathophysiological mechanisms, is able to identify patients with the highest risk of heart failure progression.
