RESUMO

BACKGROUND: Intrarenal venous flow (IRVF) measured by Doppler ultrasound has gained interest as a potential surrogate marker of renal congestion and adverse outcomes in heart failure. In this work, we aimed to determine if antigen carbohydrate 125 (CA125) and plasma amino-terminal pro-B-type natriuretic peptide (NT-proBNP) are associated with congestive IRVF patterns (i.e., biphasic and monophasic) in acute heart failure (AHF). METHODS AND RESULTS: We prospectively enrolled a consecutive cohort of 70 patients hospitalized for AHF. Renal Doppler ultrasound was assessed within the first 24-h of hospital admission. The mean age of the sample was 73.5 ± 12.3 years; 47.1% were female, and 42.9% exhibited heart failure with preserved ejection fraction. The median (interquartile range) for NT-proBNP and CA125 were 6149 (3604-12 330) pg/mL and 64 (37-122) U/mL, respectively. The diagnostic performance of both exposures for identifying congestive IRVF patterns was tested using the receiving operating curve (ROC). The cut-off for CA125 of 63.5 U/mL showed a sensibility and specificity of 67% and 74% and an area under the ROC curve of 0.71. After multivariate adjustment, CA125 remained non-linearly and positively associated with congestive IRVF (P-value = 0.008) and emerged as the most important covariate explaining the variability of the model (R2: 47.5%). Under the same multivariate setting, NT-proBNP did not show to be associated with congestive IRVF patterns (P-value = 0.847). CONCLUSIONS: CA125 and not NT-proBNP is a useful marker for identifying patients with AHF and congestive IRVF patterns.

RESUMO

INTRODUCTION AND OBJECTIVES: Discordant data have been reported on the prognosis of myocardial infarction with nonobstructive coronary arteries (MINOCA). Moreover, few data are available on the impact of angiographic subtypes. The objectives of this study were to assess the prognostic impact on the long-term follow-up of the diagnosis of MINOCA and its angiographic subtypes. METHODS: We included 591 consecutive patients with non-ST-segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography. MINOCA was classified according to angiographic findings as smooth coronary arteries, mild irregularities (< 30% stenosis), and moderate atherosclerosis (30%-49% stenosis). The primary endpoint was a composite of mortality, nonfatal myocardial infarction, and revascularization (MACE) at a median of 5 years of follow-up. RESULTS: A total of 121 patients (20.5%) showed no obstructive lesions. MINOCA was associated with a lower occurrence of MACE (P=.014; HR, 0.63; 95%CI, 0.44-0.91) and was confirmed as an independent factor in the multivariate analysis (P=.018; HR, 0.63; 95%CI, 0.43-0.92). On analysis of the separate components of the main endpoint, MINOCA was significantly associated with a lower rate of myocardial infarction and revascularization, but not with mortality. Analysis of angiographic subtypes among MINOCA patients showed that smooth coronary arteries were a statistically significant protective factor on both univariate and multivariate analysis, while mild irregularities and 30% to 49% plaques were associated with a higher risk of MACE. CONCLUSIONS: MINOCA is associated with a lower rate of MACE, driven by fewer reinfarctions and revascularizations. Within the angiographic subtypes of MINOCA, smooth arteries were independently associated with a lower number of MACE.

RESUMO

BACKGROUND: Older adult patients with frailty are rarely involved in rehabilitation programs after myocardial infarction. Our aim was to investigate the benefits of exercise intervention in these patients. METHODS: A total of 150 survivors after acute myocardial infarction, ≥70 years and with pre-frailty or frailty (Fried scale ≥1 points), were randomized to control (n = 77) or intervention (n = 73) groups. The intervention consisted of a 3-month exercise program, under physiotherapist supervision, followed by an independent home-based program. The main outcome was frailty (Fried scale) at 3 months and 1 year. Secondary endpoints were clinical events (mortality or any readmission) at 1 year. RESULTS: Mean age was 80 years (range = 70-96). In the intervention group, 44 (60%) out of 73 patients participated in the program and 23 (32%) completed it. Overall, there was a decrease in the Fried score in the intervention group at 3 months, with no effect at 1 year. However, in the intention-to-treat analysis, such change did not achieve statistical significance (P = 0.110). Only treatment comparisons made among the subgroups that participated in (P = 0.033) and completed (P = 0.018) the program achieved statistical significance. There were no differences in clinical events. Worse Fried score trajectory along follow-up increased mortality risk (hazard ratio [HR] = 2.38, 95% confidence interval [CI] 1.24-4.55, P = 0.009) CONCLUSIONS: Recruitment and retention for a physical program in older adult patients with frailty after myocardial infarction was challenging. Frailty status improved in the subgroup that participated in the program, although this benefit was attenuated after shifting to a home-based program. A better frailty trajectory might influence midterm prognosis. (ClinicalTrials.govNCT02715453).

RESUMO

BACKGROUND: Identifying patients at risk of poor diuretic response in acute heart failure (AHF) is critical to make prompt adjustments in therapy. The objective of this study was to investigate whether the circulating levels of soluble ST2 predict the cumulative diuretic efficiency (DE) at 24 and 72 hours in patients with AHF and concomitant renal dysfunction. METHODS AND RESULTS: This is a post hoc analysis of the IMPROVE-HF trial, in which we enrolled 160 patients with AHF and renal dysfunction (estimated glomerular filtrate rate of <60 mL/min/1.73 m2). DE was calculated as the net fluid output produced per 40 mg of furosemide equivalents. The association between sST2 and DE was evaluated by using multivariate linear regression analysis. The median cumulative DE at 24 and 72 hour was 747 mL (interquartile range 490-1167 mL) and 1844 mL (interquartile range 1142-2625 mL), respectively. The median sST2 and mean estimated glomerular filtrate rate were 72 ng/mL (interquartile range 47-117 ng/mL), and 34.0 ± 8.5 mL/min/1.73 m2, respectively. In a multivariable setting, higher sST2 were significant and nonlinearly related to lower DE both at 24 and 72 hours (P = .002 and P = .019, respectively). CONCLUSIONS: In patients with AHF and renal dysfunction at presentation, circulating levels of sST2 were independently and negatively associated with a poor diuretic response, both at 24 and 72 hours.

RESUMO

BACKGROUND: This case illustrates the evaluation of a healthy young male with ECG anomalies in a perioperative electrocardiogram (ECG) that ended up with the diagnosis of a severe systemic disease. CASE: A 28-year-old man was attended at the outpatient cardiology department to perform a preoperative ECG for lacrimal duct obstruction surgery, which showed Q and T negative waves in inferior leads. Echocardiogram and cardiac magnetic resonance (CMR) displayed left ventricular (LV) aneurysm at basal segments of the inferior, posterior, and lateral wall with myocardial thinning and dyskinesia. CMR and thoracic computed tomography (CT) showed bilateral nodular images in parotid glands, cervical, and thoracic lymphadenopathies. All those findings suggested the diagnosis of sarcoidosis, which was supported by Gallium-67 single-photon emission computed tomography (SPECT) results and finally confirmed by skin biopsy. CONCLUSIONS: The present case highlights the complexity of sarcoidosis diagnosis. This young male was apparently asymptomatic; however, at presentation, he actually had three manifestations of active sarcoidosis: lacrimal duct obstruction, skin lesions, and cervical lymphadenopathies. It is essential to have a low threshold for sarcoidosis suspicion in the setting of unexplained systemic signs and symptoms.

RESUMO

OBJECTIVE: In acute heart failure (AHF), early assessment of spot urinary sodium (UNa) has emerged as a useful biomarker for risk stratification and monitoring. The objective of this study was to investigate (a) whether early spot UNa predicts 24-h diuretic efficiency and (b) the clinical factors associated with early spot UNa in patients with AHF and concomitant renal dysfunction (RD). METHODS: This is a post hoc analysis of the IMPROVE-HF trial, in which 160 patients with AHF and RD (estimated glomerular filtrate rate [eGFR] <60 mL/min/1.73 m2) were included. Diuretic efficiency was calculated as the net fluid output produced per 40 mg of furosemide equivalents in 24 h. The association between early spot UNa and diuretic efficiency and clinical variables associated with UNa were evaluated using multivariate linear regression analysis. The contribution of the exposures in the predictability of the models was assessed with the coefficient of determination (R2). RESULTS: The mean age of the study population was 78 ± 8 years. The median (interquartile range) diuretic efficiency, early spot UNa, aminoterminal pro-brain natriuretic peptide, and eGFR were 747 (490-1,167) mL, 90 mmol/L (65-111), 7,765 pg/mL (3,526-15,369), and 33.7 ± 11.3 mL/min/1.73 m2, respectively. In a multivariate setting, lower UNa was significantly and nonlinearly associated with lower diuretic efficiency (p = 0.001), explaining the 44.4% of the model predictability. Natremia and surrogates of congestion emerged as the main factors related to UNa. CONCLUSIONS: In patients with AHF and RD at presentation, early spot UNa was inversely related to 24-h diuretic efficiency.

RESUMO

OBJECTIVES: This study explored the association of ischemic burden, as measured by vasodilator stress cardiovascular magnetic resonance (CMR), with all-cause mortality and the effect of revascularization on all-cause mortality in patients with stable ischemic heart disease (SIHD). BACKGROUND: In patients with SIHD, the association of ischemic burden, derived from vasodilator stress CMR, with all-cause mortality and its role for decision-making is unclear. METHODS: The registry consisted of 6,389 consecutive patients (mean age: 65 ± 12 years; 38% women) who underwent vasodilator stress CMR for known or suspected SIHD. The ischemic burden (at stress first-pass perfusion imaging) was computed (17-segment model). The effect of CMR-related revascularization (within the following 3 months) on all-cause mortality was retrospectively explored using the electronic regional health system registry. RESULTS: During a 5.75-year median follow-up, 717 (11%) deaths were documented. In multivariable analyses, more extensive ischemic burden (per 1-segment increase) was independently related to all-cause mortality (hazard ratio: 1.04; 95% confidence interval: 1.02 to 1.07; p < 0.001). In 1,032 1:1 matched patients using a limited number of variables (516 revascularized, 516 non-revascularized), revascularization within the following 3 months was associated with less all-cause mortality only in patients with extensive CMR-related ischemia (>5 segments, n = 432; 10% vs. 24%; p = 0.01). CONCLUSIONS: In a large retrospective registry of unselected patients with known or suspected SIHD who underwent vasodilator stress CMR, extensive ischemic burden was related to a higher risk of long-term, all-cause mortality. Revascularization was associated with a protective effect only in the restricted subset of patients with extensive CMR-related ischemia. Further research will be needed to confirm this hypothesis-generating finding.

RESUMO

OBJECTIVES: Initial data on COVID-19 infection has pointed out a special vulnerability of older adults. DESIGN: We performed a meta-analysis with available national reports on May 7, 2020 from China, Italy, Spain, United Kingdom, and New York State. Analyses were performed by a random effects model, and sensitivity analyses were performed for the identification of potential sources of heterogeneity. SETTING AND PARTICIPANTS: COVID-19-positive patients reported in literature and national reports. MEASURES: All-cause mortality by age. RESULTS: A total of 611,1583 subjects were analyzed and 141,745 (23.2%) were aged ≥80 years. The percentage of octogenarians was different in the 5 registries, the lowest being in China (3.2%) and the highest in the United Kingdom and New York State. The overall mortality rate was 12.10% and it varied widely between countries, the lowest being in China (3.1%) and the highest in the United Kingdom (20.8%) and New York State (20.99%). Mortality was <1.1% in patients aged <50 years and it increased exponentially after that age in the 5 national registries. As expected, the highest mortality rate was observed in patients aged ≥80 years. All age groups had significantly higher mortality compared with the immediately younger age group. The largest increase in mortality risk was observed in patients aged 60 to 69 years compared with those aged 50 to 59 years (odds ratio 3.13, 95% confidence interval 2.61-3.76). CONCLUSIONS AND IMPLICATIONS: This meta-analysis with more than half million of COVID-19 patients from different countries highlights the determinant effect of age on mortality with the relevant thresholds on age >50 years and, especially, >60 years. Older adult patients should be prioritized in the implementation of preventive measures.

RESUMO

La infección por SARS-CoV-2, denominada COVID-19 (Coronavirus Infectious Disease-19), es una enfermedad desconocida hasta diciembre de 2019 a la que nos enfrentamos en España desde el 31 de enero de 2020 -fecha del primer caso diagnosticado en nuestro país- y que ya ha causado la muerte de 7.340 personas (a 30 de marzo de 2020), sobre todo mayores. Es importante tener en cuenta que, dado que la información evoluciona con extremada rapidez en este campo, lo expuesto en el presente documento puede estar sujeto a modificaciones. La población de mayor edad es especialmente susceptible a la infección por COVID-19, así como a desarrollar criterios de gravedad. Este aumento de morbimortalidad en el paciente mayor se ha asociado tanto con las comorbilidades, especialmente la enfermedad cardiovascular, como con la situación de fragilidad, que conlleva una respuesta inmunológica más pobre. La situación actual, tanto por los países afectados como por el número de casos, constituye una pandemia y supone una emergencia sanitaria de primer nivel. Como España es uno de los países más envejecidos del mundo, la COVID-19 se ha convertido en una emergencia geriátrica. El presente documento se ha elaborado conjuntamente entre la Sección de Cardiología Geriátrica de la Sociedad Española de Cardiología y la Sociedad Española de Geriatría y Gerontología


SARS-CoV2 infection, also known as COVID-19 (coronavirus infectious disease-19), was first identified in December 2019. In Spain, the first case of this infection was diagnosed on 31 January, 2020 and, by 30 March 2020, has caused 7340 deaths, especially in the elderly. Due to the rapidly evolving situation regarding this disease, the data reported in this article may be subject to modifications. The older population are particularly susceptible to COVID-19 infection and to developing severe disease. The higher morbidity and mortality rates in older people have been associated with comorbidity, especially cardiovascular disease, and frailty, which weakens the immune response. Due to both the number of affected countries and the number of cases, the current situation constitutes an ongoing pandemic and a major health emergency. Because Spain has one of the largest older populations in the world, COVID-19 has emerged as a geriatric emergency. This document has been prepared jointly between the Geriatric Cardiology Section of the Spanish Society of Cardiology and the Spanish Society of Geriatrics and Gerontology
