Background Tricuspid regurgitation (TR) is common in chronic heart failure (HF) and is associated with negative prognosis. However, evidence on prognostic implications of TR in acute HF (AHF) is lacking. Objectives We sought to investigate the association between TR and mortality and the interaction with pulmonary hypertension (PH) in patients admitted for AHF. Methods We enrolled 1176 consecutive patients with a primary diagnosis of AHF and with available non-invasive estimation of TR and pulmonary arterial systolic pressure (PASP). Results Moderate-severe TR was present in 352 patients (29.9%) and was associated with older age and more comorbidities. The prevalence of PH (i.e., PASP>40mmHg), right ventricular dysfunction (RVD) and mitral regurgitation (MR) was higher in moderate-severe TR. At 1 year, 184 (15.6%) patients died. Moderate-severe TR was associated with higher 1-year mortality risk after adjustment for other echocardiographic parameters (PASP, left ventricle ejection fraction – LVEF, RVD and MR; HR=1.623, p=0.004) and the association with outcome was maintained when clinical variables were added to the multivariable model (HR=1.515, p=0.035). The association between moderate-severe TR and outcome was consistent in patients with vs without PH, with vs without RVD, and with vs without LVEF<50%. Patients with coexistent moderate-severe TR and PH had 3-fold higher 1-year mortality risk compared to patients with no TR or PH (HR=2.920, p<0.001). Conclusions In patients hospitalized for AHF, the severity of TR is associated with 1-year survival, regardless of the presence of PH. However, the combination of moderate-severe TR and PH conferred a further incremental mortality risk.
(1) Background: Among the different cardiovascular (CV) manifestations of the coronavirus disease 2019 (COVID-19), arrhythmia and atrial fibrillation (AF) in particular have recently received special attention. The aims of our study were to estimate the incidence of AF in patients hospitalized for COVID-19, and to evaluate its role as a possible predictor of in-hospital all-cause mortality. (2) Methods: We enrolled 3435 people with SARS-CoV2 infection admitted to three hospitals in Northern Italy from February 2020 to May 2021. We collected data on their clinical history, laboratory tests, pharmacological treatment and intensive care unit (ICU) admission. Incident AF and all-cause in-hospital mortality were considered as outcomes. (3) Results: 145 (4.2%) patients developed AF during hospitalization, with a median time since admission of 3 days (I-III quartile: 0, 12). Patients with incident AF were admitted more frequently to the ICU (39.3 vs. 12.4%, p < 0.001), and more frequently died (37.2 vs. 16.9%, p < 0.001). In the Cox regression model, the significant determinants of incident AF were age (HR: 1.041; 95% CI: 1.022, 1.060 per year), a history of AF (HR: 2.720; 95% CI: 1.508, 4.907), lymphocyte count (HR: 0.584; 95% CI: 0.384, 0.888 per 103/µL), estimated glomerular filtration rate (eGFR, HR: 0.988; 95% CI: 0.980, 0.996 per mL/min) and ICU admission (HR: 5.311; 95% CI: 3.397, 8.302). Incident AF was a predictor of all-cause mortality (HR: 1.405; 95% CI: 1.027, 1.992) along with age (HR: 1.057; 95% CI: 1.047, 1.067), male gender (HR: 1.315; 95% CI: 1.064; 1.626), dementia (HR: 1.373; 95% CI: 1.045, 1.803), lower platelet (HR: 0.997; 95% CI: 0.996, 0.998 per 103/µL) and lymphocyte counts (HR: 0.843; 95% CI: 0.725, 0.982 per 103/µL), C-Reactive protein values (HR: 1.004; 95% CI: 1.003, 1.005 per mg/L), eGFR (HR: 0.990; 95% CI: 0.986, 0.994 per mL/min), and ICU admission (HR: 1.759; 95% CI: 1.292, 2.395). (4) Conclusions: Incident AF is a common complication in COVID-19 patients during hospitalization, and its occurrence strongly predicts in-hospital mortality.
Background: Tricuspid regurgitation (TR) is common in chronic heart failure (HF) and is associated with negative prognosis. However, evidence on prognostic implications of TR in acute HF is lacking. We sought to investigate the association between TR and mortality and the interaction with pulmonary hypertension (PH) in patients admitted for acute HF. Methods: We enrolled 1176 consecutive patients with a primary diagnosis of acute HF and with available noninvasive estimation of TR and pulmonary arterial systolic pressure. Results: Moderate-severe TR was present in 352 patients (29.9%) and was associated with older age and more comorbidities. The prevalence of PH (ie, pulmonary arterial systolic pressure >40 mm Hg), right ventricular dysfunction, and mitral regurgitation was higher in moderate-severe TR. At 1 year, 184 (15.6%) patients died. Moderate-severe TR was associated with higher 1-year mortality risk after adjustment for other echocardiographic parameters (pulmonary arterial systolic pressure, left ventricle ejection fraction, right ventricular dysfunction, mitral regurgitation, left and right atrial indexed volumes; hazard ratio, 1.718; P =0.009), and the association with outcome was maintained when clinical variables (eg, natriuretic peptides, serum creatinine and urea, systolic blood pressure, atrial fibrillation) were added to the multivariable model (hazard ratio, 1.761; P =0.024). The association between moderate-severe TR and outcome was consistent in patients with versus without PH, with versus without right ventricular dysfunction, and with versus without left ventricle ejection fraction <50%. Patients with coexistent moderate-severe TR and PH had 3-fold higher 1-year mortality risk compared with patients with no TR or PH (hazard ratio, 3.024; P <0.001). Conclusions: In patients hospitalized for acute HF, the severity of TR is associated with 1-year survival, regardless of the presence of PH. The coexistence of moderate-severe TR and estimated PH was associated with a further increase in mortality risk. Our data must be interpreted in the context of potential underestimation of pulmonary arterial systolic pressure in patients with severe TR.
A 60-year-old man with a previous myocardial infarction was admitted to our ICU for acute pulmonary edema in the context of an acute antero-lateral non-ST elevation myocardial infarction. Echocardiography showed severe left ventricular (LV) dilatation with extensive wall motion abnormalities, large apical aneurysm and severe systolic dysfunction. Coronary angiography showed a triple-vessel disease with proximal occlusion of the left anterior descending artery. During the hospitalization, multiple episodes of drug-resistant monomorphic ventricular tachycardias occurred, requiring repeated DC Shock. After Heart Team discussion, the patient underwent coronary artery bypass grafting, LV restoration according to the procedure described by Guilmet and surgical cryoablation. The Guilmet septoexclusion is indicated when the interventricular septum is more involved than the free wall. After aneurysm incision, cryolesions were applied at the septum and at the transitional zone of the scar and viable tissue. Thus, the anterior free wall was sewn obliquely to the septum. Finally, the edges of the incision, anterior and septal, were sewn together to assure a definitive hemostasis (overcoat technique). After surgery, an implantable cardioverter-defibrillator was implanted in secondary prevention. The postoperative course and subsequent cardiological follow-up were characterized by a gradual clinical improvement with mild increasing in LV function and reduction in ventricular arrhythmias. Nowadays, combined aneurysmectomy and endocardial ablation are rarely performed, but should be considered in patients with LV aneurysm who manifest drug-resistant ventricular arrhythmias. Encircling cryoablation in a remodelled ventricle is safe and effective in reducing ventricular arrhythmias which are a negative prognostic factor.
