Baseline NT-proBNP levels as a predictor of short-and long-term prognosis in COVID-19 patients: a prospective observational study.

BACKGROUND: Up to 20% of COVID-19 patients can suffer COVID-19-related myocardial injury. Elevated cardiac biomarkers, such as hs-cTnT and NT-proBNP, have been related to worse short-term prognosis. However, data on NT-proBNP and long-term prognosis are scarce. We have evaluated the potential association of baseline age-adjusted NT-proBNP levels and outcomes at one-year follow-up in COVID-19 patients. METHODS: This was a single-center prospective study of 499 COVID-19 patients in whom NT-proBNP was assessed at hospital admission. NT-proBNP levels were age-adjusted and patients were classified as high or low NT-proBNP. Clinical and demographic characteristics, comorbidities, laboratory results, and in-hospital complications and mortality were compared between the two groups. Survivors of the acute phase of COVID-19 were followed up for one year from admission to detect readmissions and mortality. RESULTS: The 68 patients with high NT-proBNP levels at hospital admission were older, with more cardiovascular risk factors, cardiovascular disease, comorbidities, myocardial injury, and higher levels of inflammatory markers than patients with low NT-proBNP levels. They also had more in-hospital complications and a higher acute-phase mortality rate (60.3% vs. 10.2%, p < 0.001). High NT-proBNP levels were an independent marker of death during hospitalization (HR 1.95; CI 1.07-3.52). At one-year follow-up, high NT-proBNP levels were independently associated with mortality (HR 2.69; CI 1.47-4.89). Among survivors of the acute phase of COVID-19, there were no differences in hospital readmissions between those with high vs. low NT-proBNP levels, but survivors with high baseline NT-proBNP levels showed a higher 1-year mortality rate (7.4% vs. 1.3%, p = 0.018). CONCLUSIONS: High age-adjusted NT-proBNP levels at the time of hospital admission for COVID-19 are associated with poor short and long-term prognosis. High NT-proBNP seems also to be related to worse prognosis in survivors of the acute phase of COVID-19. A closer follow-up on these patients may be crucial.

Subclinical congestion assessed by lung ultrasound in ST segment elevation myocardial infarction.

OBJECTIVE: We evaluated the prognostic value of subclinical congestion assessed by lung ultrasound (LUS) in patients admitted for ST segment elevation myocardial infarction (STEMI). METHODS: This was a multicentre study that prospectively enrolled 312 patients admitted for STEMI without signs of heart failure (HF) at admission. LUS was performed during the first 24 hours after revascularisation and classified patients as having either wet lung (three or more B-lines in at least one lung field) or dry lung. The primary endpoint was a composite of acute HF, cardiogenic shock or death during hospitalisation. The secondary endpoint was a composite of readmission for HF or new acute coronary syndrome or death during 30-day follow-up. Zwolle score was calculated in all patients to assess predictive improvement by adding the result of the LUS to this score. RESULTS: 14 patients (31.1%) in the wet lung group presented the primary endpoint vs 7 (2.6%) in the dry lung group (adjusted RR 6.0, 95% CI 2.3 to 16.2, p=0.007). The secondary endpoint occurred in five patients (11.6%) in the wet lung group and in three (1.2%) in the dry lung group (adjusted HR 5.4, 95% CI 1.0 to 28.7, p=0.049). Addition of LUS improved the ability of the Zwolle score to predict the follow-up composite endpoint (net reclassification improvement 0.99). LUS showed a very high negative predictive value in predicting in-hospital and follow-up endpoints (97.4% and 98.9%, respectively). CONCLUSION: Early subclinical pulmonary congestion identified by LUS in patients with Killip I STEMI at hospital admission is associated with adverse outcomes during hospitalisation and 30-day follow-up.

Myocardial Injury in COVID-19 and Its Implications in Short- and Long-Term Outcomes.

COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still a pandemic with high mortality and morbidity rates. Clinical manifestation is widely variable, including asymptomatic or mild respiratory tract illness to severe pneumonia and death. Myocardial injury is a significant pathogenic feature of COVID-19 and it is associated with worse in-hospital outcomes, mainly due to a higher number of hospital readmissions, with over 50% mortality. These findings suggest that myocardial injury would identify COVID-19 patients with higher risk during active infection and mid-term follow-up. Potential contributors responsible for myocardial damage are myocarditis, vasculitis, acute inflammation, type 1 and type 2 myocardial infarction. However, there are few data about cardiac sequelae and its long-term consequences. Thus, the optimal screening tool for residual cardiac sequelae, clinical follow-up, and the benefits of a specific cardiovascular therapy during the convalescent phase remains unknown. This mini-review explores the different mechanisms of myocardial injury related to COVID-19 and its short and long-term implications.

El déficit de hierro es un determinante de la capacidad funcional y de la calidad de vida a los 30 días tras un síndrome coronario agudo / Iron deficiency is a determinant of functional capacity and health-related quality of life 30 days after an acute coronary syndrome

Introducción y objetivos: El déficit de hierro (DH) es una condición frecuente en pacientes con cardiopatía isquémica o insuficiencia cardiaca. Pero se desconoce su impacto en la capacidad funcional y la calidad de vida (CdV) tras un síndrome coronario agudo (SCA). Métodos: Se evaluó prospectivamente el impacto del DH en la capacidad funcional y la CdV de 244 pacientes 30 días después de haber sufrido un SCA. La CdV se evaluó mediante el test EuroQol-5 dimensiones, la escala visual analógica y el Heart-QoL. La capacidad funcional se midió mediante ergometría en cinta sin fin o con la prueba de los 6 min de marcha. Se evaluó el impacto del DH en la morbimortalidad cardiovascular. Resultados: Se documentó DH en el 46% de los pacientes. Estos pacientes realizaban ejercicio menos tiempo (366 ± 162 frente a 462 ± 155 s; p < 0,001), presentaban peores tasas metabólicas de consumo (7,9 ± 2,9 frente a 9,3 ± 2,6 equivalentes metabólicos; p = 0,003) y peor CdV, con puntuaciones más bajas en el EuroQol-5 dimensiones (0,76 ± 0,25 frente a 0,84 ± 0,16), la escala visual analógica (66 ± 16 frente a 72 ± 17) y el Heart-QoL (1,9 ± 0,6 frente a 2,2 ± 0,6) (todas, p < 0,05). El DH fue un predictor independiente de peor capacidad funcional (OR = 2,9; IC95%, 1,1-7,6; p = 0,023) y peor CdV (OR = 1,9; IC95%, 1,1-3,3; p < 0,001). No se observó efecto en la morbimortalidad cardiovascular. Conclusiones: El DH implica peor capacidad funcional y peor calidad de vida a medio plazo tras un SCA (AU)

Background and objectives: Iron deficiency (ID) is a prevalent condition in patients with ischemic heart disease and heart failure. Little is known about the impact of ID on exercise capacity and quality of life (QoL) in the recovery phase after an acute coronary syndrome (ACS). Methods: Iron status and its impact on exercise capacity and QoL were prospectively evaluated in 244 patients 30 days after the ACS. QoL was assessed by the standard EuroQoL-5 dimensions, EuroQoL visual analogue scale, and Heart-QoL questionnaires. Exercise capacity was analyzed by treadmill/6-minute walk tests. The effect of ID on cardiovascular mortality and readmission rate was also investigated. Results: A total of 46% of the patients had ID. These patients had lower exercise times (366 ± 162 vs 462 ± 155 seconds; P < .001), metabolic consumption rates (7.9 ± 2.9 vs 9.3 ± 2.6 METS; P = .003), and EuroQoL-5 dimensions (0.76 ± 0.25 vs 0.84 ± 0.16), visual analogue scale (66 ± 16 vs 72 ± 17), and Heart-QoL (1.9 ± 0.6 vs 2.2 ± 0.6) scores (P < .05). ID independently predicted lower exercise times (OR, 2.9; 95%CI, 1.1-7.6; P = .023) and worse QoL (OR, 1.9; 95%CI, 1.1-3.3; P < .001) but had no effect on cardiovascular morbidity or mortality. Conclusions: ID, a prevalent condition in ACS patients, results in a poorer mid-term functional recovery, as measured by exercise capacity and QoL (AU)
