- Recent European Society of Cardiology and American Heart Association/American College of Cardiology Guidelines did not recommend biomarker-guided therapy in the management of heart failure (HF) patients. Combination of echo- and B-type natriuretic peptide (BNP) may be an alternative approach in guiding ambulatory HF management. Our aim was to determine whether a therapy guided by echo markers of left ventricular filling pressure (LVFP), lung ultrasound (LUS) assessment of B-lines, and BNP improves outcomes of HF patients. Consecutive outpatients with LV ejection fraction (EF) <= 50% have been prospectively enrolled. In Group I (n=224), follow-up was guided by echo and BNP with the goal of achieving E-wave deceleration time (EDT) >= 150 ms, tissue Doppler index E/e' < 13, B-line numbers < 15, and BNP <= 125 pg/ml or decrease > 30%; in Group II (n=293), follow-up was clinically guided, while the remaining 277 patients (Group III) did not receive any dedicated follow-up. At 60 months, survival was 88% in Group I compared to 75% in Group II and 54% in Group III (chi(2) 53.5; p<0.0001). Survival curves exhibited statistically significant differences using Mantel-Cox analysis. The number needed to treat to spare one death was 7.9 (Group I versus Group II) and 3.8 (Group I versus Group III). At multivariate Cox regression analyses, major predictors of all-cause mortality were follow-up E/e' (HR: 1.05; p=0.0038) and BNP > 125 pg/ml or decrease <= 30% (HR: 4.90; p=0.0054), while BNP > 125 pg/ml or decrease <= 30% and B-line numbers >= 15 were associated with the combined end point of death and HF hospitalization. Evidence-based HF treatment guided by serum biomarkers and ultrasound with the goal of reducing elevated BNP and LVFP, and resolving pulmonary congestion was associated with better clinical outcomes and can be valuable in guiding ambulatory HF management.

- Background and Aim: Predictors of exercise capacity in heart failure (HF) with preserved ejection fraction (HFpEF) remain of difficult determination. The aim of this study was to identify predictors of exercise capacity in a group of patients with HFpEF and right ventricle (RV) dysfunctionMethods: In 143 consecutive patients with HFpEF (age 62 ± 9 years, LV EF ≥45) and 41 controls, a complete echocardiographic study was performed. In addition to conventional measurements, LA compliance was calculated using the formula: [LAV max − LAV min/LAV min × 100]. Exercise capacity was assessed using the six‐minute walking test (6‐MWT). Tricuspid annular plane systolic excursion (TAPSE) < 1.7 cm was utilized to categorize patients with RV dysfunction (n = 40) from those with maintained RV function (n = 103).Results: Patients with RV dysfunction were older (P = 0.002), had higher NYHA class (P = 0.001), higher LV mass index (P = 0.01), reduced septal and lateral MAPSE (all P < 0.001), enlarged LA (P = 0.001) impaired LA compliance index (P < 0.001) and exhibited a more compromised 6‐MWT (P = 0.001). LA compliance index correlated more closely with 6‐MWT (r = 0.51, P < 0.001) compared with the other LA indices (AP diameter, transverse diameter and volume indexed; r = −0.30, r = −0.35 and r = −0.38, respectively). In multivariate analysis, LA compliance index <60% was 88% sensitive and 61% specific (AUC 0.80, CI = 0.67–0.92 P = 0.001) in predicting exercise capacity.Conclusion: An impairment in LA compliance was profound in patients with HFpEF and RV dysfunction and seems to be most powerful independent predictor of limited exercise capacity.

- Background and Aim: Left atrial stiffness (LASt) is an important marker of cardiac function, especially in patients with heart failure (HF); it explains symptoms on the basis of pressure transfer to the pulmonary circulation. The aim of this study was to evaluate the relationship between LASt and cardiac events (CE) in HF patients with reduced to mid-range ejection fraction.Methods: The study included 215 consecutive ambulatory HF patients with ejection fraction (EF) < 50% (162 HF reduced EF and 53 HF mid-range EF) of mean age 66 +/- 11 years and 24.4% females. Peak LA strain (PALS) was measured by speckle tracking echocardiography and E/e' recorded from the apical four-chamber view. Non-invasive LASt was calculated using the equation: LASt = E/e' ratio/PALS. Documented cardiac events (CE) were HF hospitalization and cardiac death.Results: During a median follow up of 41 +/- 34 months, 65 patients (30%) had CE. In multivariate analysis model, only raised LV filling pressure (E/e') (OR = 0.292, (95% CI 0.099 to 0.859), p = 0.02), peak pulmonary artery pressure (PAP) (OR = 1.050 (1.009 to 1.094), p = 0.01), PALS (OR = 0.932 (0.873 to 0.994), p = 0.02) and LASt (OR = 3.781 (1.144 to 5.122), p = 0.001) independently predicted CE. LASt >= 0.76% was the most powerful predictor of CE, with 80% sensitivity and 73% specificity (AUC 0.82, CI = 0.73 to 0.87, p < 0.001) followed by PALS <= 16%, with 74% sensitivity and 72% specificity (AUC 0.77, CI = 0.71 to 0.84, p < 0.001). These results were consistent irrespective of EF (p < 0.05).Conclusion: In this cohort of ambulatory HFrEF and HFmrEF patients, LASt proved the most powerful predictor of clinical outcome.

- Background: The long COVID-19 syndrome has been recently described and some reports have suggested that acute pericarditis represents important manifestation of long COVID-19 syndrome. The aim of this study was to identify the prevalence and clinical characteristics of patients with long COVID-19, presenting with acute pericarditis.Methods: We retrospectively included 180 patients (median age 47 years, 62% female) previously diagnosed with COVID-19, exhibiting persistence or new-onset symptoms ≥12 weeks from a negative naso-pharyngeal SARS CoV2 swamp test. The original diagnosis of COVID-19 infection was determined by a positive swab. All patients had undergone a thorough physical examination. Patients with suspected heart involvement were referred to a complete cardiovascular evaluation. Echocardiography was performed based on clinical need and diagnosis of acute pericarditis was achieved according to current guidelines.Results: Among the study population, shortness of breath/fatigue was reported in 52%, chest pain/discomfort in 34% and heart palpitations/arrhythmias in 37%. Diagnosis of acute pericarditis was made in 39 patients (22%). Mild-to-moderate pericardial effusion was reported in 12, while thickened and bright pericardial layers with small effusions (< 5 mm) with or without comet tails arising from the pericardium (pericardial B-lines) in 27. Heart palpitations/arrhythmias (OR:3.748, p = 0.0030), and autoimmune disease and allergic disorders (OR:4.147, p = 0.0073) were independently related to the diagnosis of acute pericarditis, with a borderline contribution of less likelihood of hospitalization during COVID-19 (OR: 0.100, p = 0.0512).Conclusion: Our findings suggest a high prevalence of acute pericarditis in patients with long COVID-19 syndrome. Autoimmune and allergic disorders, and palpitations/arrhythmias were frequently associated with pericardial disease.

- BACKGROUND: International agencies reported that cases of pericarditis occur very rarely following the administration of coronavirus disease 2019 (COVID-19) vaccines. Herewith, we described a series of patients from the community diagnosed with acute pericarditis after vaccination.METHODS: We retrospectively included 28 patients (median age 51 years, 79% female) with or without a positive history of acute respiratory syndrome coronavirus 2 recovered infection who were diagnosed with acute pericarditis following the administration of COVID-19 vaccine. We excluded specific identifiable causes of pericarditis, including infectious, autoimmune, neoplastic and metabolic disease. Patients were referred for a complete cardiovascular evaluation. Transthoracic echocardiography (TTE) was performed and diagnosis of acute pericarditis was achieved according to current guidelines.RESULTS: There were 16 patients administered with Pfizer-BioNTech/Comirnaty vaccine, 8 with Moderna/Spikevax vaccine and 4 with Astra Zeneca/Vaxzevria vaccine. Nine patients had been previously diagnosed with COVID-19, while the others had no prior history of COVID-19. Eleven patients had no comorbidity while the others had between one and four comorbidities. Ten patients had a history of rheumatic or autoimmune diseases. Chest pain was present in 24 patients. Minor ECG abnormalities were detected in 10 patients, T-wave inversion in 6, and 7 patients had concave ST elevation. The majority of patients showed mild pericardial effusions at TTE. Only two patients exhibited large pericardial effusions.CONCLUSION: This case series shows a higher incidence of acute pericarditis in patients administered with COVID-19 vaccines than previously estimated, probably because of a more comprehensive assessment of clinical as well as echocardiographic parameters.

- Heart failure (HF) is a progressive condition with a clinical picture resulting from reduced cardiac output (CO) and/or elevated left ventricular (LV) filling pressures (LVFP). The original Diamond-Forrester classification, based on haemodynamic data reflecting CO and pulmonary congestion, was introduced to grade severity, manage, and risk stratify advanced HF patients, providing evidence that survival progressively worsened for those classified as warm/dry, cold/dry, warm/wet, and cold/wet. Invasive haemodynamic evaluation in critically ill patients has been replaced by non-invasive haemodynamic phenotype profiling using echocardiography. Decreased CO is not infrequent among ambulatory HF patients with reduced ejection fraction, ranging from 23 to 45%. The Diamond-Forrester classification may be used in combination with the evaluation of natriuretic peptides (NPs) in ambulatory HF patients to pursue the goal of early identification of those at high risk of adverse events and personalise therapy to antagonise neurohormonal systems, reduce congestion, and preserve tissue/renal perfusion. The most benefit of the Guideline-directed medical treatment is to be expected in stable patients with the warm/dry profile, who more often respond with LV reverse remodelling, while more selective individualised treatments guided by echocardiography and NPs are necessary for patients with persisting congestion and/or tissue/renal hypoperfusion (cold/dry, warm/wet, and cold/wet phenotypes) to achieve stabilization and to avoid further neurohormonal activation, as a result of inappropriate use of vasodilating or negative chronotropic drugs, thus pursuing the therapeutic objectives. Therefore, tracking the haemodynamic status over time by clinical, imaging, and laboratory indicators helps implement therapy by individualising drug regimens and interventions according to patients' phenotypes even in an ambulatory setting.

Right ventricular failure in left heart disease : from pathophysiology to clinical manifestations and prognosis
- 2023

Ingår i: Heart Failure Reviews. - : Springer Netherlands. - 1382-4147 .- 1573-7322. ; 28:4, s. 757-766

Forskningsöversikt (refereegranskat)abstract
- Right heart failure (RHF) is a clinical syndrome in which symptoms and signs are caused by dysfunction and/or overload of the right heart structures, predominantly the right ventricle (RV), resulting in systemic venous hypertension, peripheral oedema and finally, the impaired ability of the right heart to provide tissue perfusion. Pathogenesis of RHF includes the incompetence of the right heart to maintain systemic venous pressure sufficiently low to guarantee an optimal venous return and to preserve renal function. Virtually, all myocardial diseases involving the left heart may be responsible for RHF. This may result from coronary artery disease, hypertension, valvular heart disease, cardiomyopathies and myocarditis. The most prominent clinical signs of RHF comprise swelling of the neck veins with an elevation of jugular venous pressure and ankle oedema. As the situation worsens, fluid accumulation becomes generalised with extensive oedema of the legs, congestive hepatomegaly and eventually ascites. Diagnosis of RHF requires the presence of signs of elevated right atrial and venous pressures, including dilation of neck veins, with at least one of the following criteria: (1) compromised RV function; (2) pulmonary hypertension; (3) peripheral oedema and congestive hepatomegaly. Early recognition of RHF and identifying the underlying aetiology as well as triggering factors are crucial to treating patients and possibly reversing the clinical manifestations effectively and improving prognosis.
