Aims Residual pulmonary congestion at hospital discharge can worsen the outcomes in patients with heart failure (HF) and can be detected by lung ultrasound (LUS). The aim of this study was to analyse the prevalence of subclinical pulmonary congestion at discharge and its impact on prognosis in patients admitted for acute HF. Methods and results This is a post-hoc analysis of the LUS-HF trial. LUS was performed by the investigators in eight chest zones with a pocket device. Physical exam was subsequently performed by the treating physicians. Primary outcome was a combined endpoint of rehospitalization, unexpected visit for HF worsening or death at 6month follow-up. Subclinical pulmonary congestion at discharge was defined as the presence of ≥5 B-lines in LUS in absence of rales in the auscultation employing the area under the ROC curve. At discharge, 100 patients (81%) did not show clinical signs of pulmonary congestion. Of these, 41 had ≥5 B-lines. Independent factors related with the presence of subclinical pulmonary congestion were anaemia, higher New York Heart Association (NYHA) class, and N terminal pro brain natriuretic peptide (NT-proBNP). After adjusting by propensity score analysis including age, renal insufficiency, atrial fibrillation, NYHA class, NT-proBNP levels, clinical congestion, and the trial intervention, the presence of subclinical pulmonary congestion at discharge was a risk factor for the occurrence of the primary outcome (hazard ratio 2.63; 95% confidence interval: 1.08-6.41; P = 0.033). Conclusions Up to 40% of patients considered 'dry' according to pulmonary auscultation presents subclinical congestion at hospital discharge that can be detected by LUS and implies a worse prognosis at 6month follow-up. Comorbidities, high values of natriuretic peptides, and higher NYHA class are the factors related with its presence.
An invasive strategy was independently associated with better outcomes in very elderly patients with NSTEACS. This association was different according to frailty status.
Background-The arrhythmogenesis of ventricular myocardial ischemia has been extensively studied, but models of atrial ischemia in humans are lacking. This study aimed at describing the electrophysiological alterations induced by acute atrial ischemia secondary to atrial coronary branch occlusion during elective coronary angioplasty. Methods and Results-Clinical data, 12-lead ECG, 12-hour Holter recordings, coronary angiography, and serial plasma levels of high-sensitivity troponin T and midregional proatrial natriuretic peptide were prospectively analyzed in 109 patients undergoing elective angioplasty of right or circumflex coronary arteries. Atrial coronary branches were identified and after the procedure patients were allocated into two groups: atrial branch occlusion (ABO, n=17) and atrial branch patency (non-ABO, n=92). In comparison with the non-ABO, patients with ABO showed: (1) higher incidence of periprocedural myocardial infarction (20% versus 53%, P=0.01); (2) more frequent intra-atrial conduction delay (19% versus 46%, P=0.03); (3) more marked PR segment deviation in the Holter recordings; and (4) higher incidence of atrial tachycardia (15% versus 41%, P=0.02) and atrial fibrillation (0% versus 12%, P=0.03). After adjustment by a propensity score, ABO was an independent predictor of periprocedural infarction (odds ratio, 3.4; 95% confidence interval, 1.01-11.6, P<0.05) and atrial arrhythmias (odds ratio, 5.1; 95% confidence interval, 1.2-20.5, P=0.02). Conclusions-Selective atrial coronary artery occlusion during elective percutaneous transluminal coronary angioplasty is associated with myocardial ischemic damage, atrial arrhythmias, and intra-atrial conduction delay. Our data suggest that atrial ischemic episodes might be considered as a potential cause of atrial fibrillation in patients with chronic coronary artery disease.
The accuracy of the admission electrocardiogram (ECG) in predicting the site of acute coronary artery occlusion in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease is not well known. This study aimed to assess whether the presence of multivessel coronary artery disease (CAD) modifies the artery-related ST-segment changes in patients with acute coronary artery occlusion. We reviewed the admission ECG, clinical records, and coronary angiography of 289 patients with STEMI caused by acute occlusion of left anterior descending (LAD; n = 140), right (n = 118), or left circumflex (LCx; n = 31) coronary arteries. All patients underwent primary percutaneous coronary reperfusion during the first 12 hours. The magnitude and distribution of artery-related ST-segment patterns were comparable in patients with single (n = 149) and multivessel (n = 140) CAD. Occlusion of proximal (n = 55) or mid-distal (n = 85) LAD artery induced ST-segment elevation in leads V1 to V5, but only the proximal occlusion induced reciprocal ST-segment depression in leads II, III, and aVF (p <0.001). Proximal and mid-distal occlusion of right (n = 45 and 73, respectively) or LCx (n = 15 and 16) coronary artery always induced ST-segment elevation in leads II, III, and aVF and reciprocal ST-segment depression in leads V2 and V3. ST-segment elevation in lead V6 >0.1 mV predicted LCx artery occlusion. In conclusion, patients with STEMI with single or multivessel CAD have concordant artery-related ST-segment patterns on the admission ECG; in both groups, reciprocal ST-segment depression in LAD artery occlusion predicts a large infarct. Subendocardial ischemia at a distance is not a requisite for the genesis of reciprocal ST-segment changes.
Background Bleeding risk scores have shown a limited predictive ability in elderly patients with acute coronary syndromes (ACS). No study explored the role of a comprehensive geriatric assessment to predict in-hospital bleeding in this clinical setting.
Methods The prospective multicentre LONGEVO-SCA registry included 532 unselected patients with non-ST segment elevation ACS (NSTEACS) aged 80 years or older. Comorbidity (Charlson index), frailty (FRAIL scale), disability (Barthel index and Lawton–Brody index), cognitive status (Pfeiffer test) and nutritional risk (mini nutritional assessment-short form test) were assessed during hospitalization. CRUSADE score was prospectively calculated for each patient. In-hospital major bleeding was defined by the CRUSADE classification. The association between geriatric syndromes and in-hospital major bleeding was assessed by logistic regression method and the area under the receiver operating characteristic curves (AUC).
Results Mean age was 84.3 years (SD 4.1), 61.7% male. Most patients had increased troponin levels (84%). Mean CRUSADE bleeding score was 41 (SD 13). A total of 416 patients (78%) underwent an invasive strategy, and major bleeding was observed in 37 cases (7%). The ability of the CRUSADE score for predicting major bleeding was modest (AUC 0.64). From all aging-related variables, only comorbidity (Charlson index) was independently associated with major bleeding (per point, odds ratio: 1.23, p = 0.021). The addition of comorbidity to CRUSADE score slightly improved the ability for predicting major bleeding (AUC: 0.68).
Conclusion Comorbidity was associated with major bleeding in very elderly patients with NSTEACS. The contribution of frailty, disability or nutritional risk for predicting in-hospital major bleeding was marginal.
