Sex differences in Cardiorenal Syndrome: Insights from CARDIOREN Registry.

PURPOSE OF THE WORK: Although sex-specific differences in heart failure (HF) or kidney disease (KD) have been analyzed separately, the predominant cardiorenal phenotype by sex has not been described. This study aims to explore the sex-related differences in cardiorenal syndrome (CRS) in a contemporary cohort of outpatients with HF. FINDINGS: An analysis of the Cardiorenal Spanish registry (CARDIOREN) was performed. CARDIOREN Registry is a prospective multicenter observational registry including 1107 chronic ambulatory HF patients (37% females) from 13 Spanish HF clinics. Estimated Glomerular Filtration Rate (eGFR) < 60 ml/min/1.73 m2 was present in 59.1% of the overall HF population, being this prevalence higher in the female population (63.2% vs. 56.6%, p = 0.032, median age: 81 years old, IQR:74-86). Among those with kidney dysfunction, women displayed higher odds of showing HF with preserved ejection fraction (HFpEF) (odds ratio [OR] = 4.07; confidence interval [CI] 95%: 2.65-6.25, p < 0.001), prior valvular heart disease (OR = 1.76; CI 95%:1.13-2.75, p = 0.014), anemia (OR: 2.02; CI 95%:1.30-3.14, p = 0.002), more advanced kidney disease (OR for CKD stage 3: 1.81; CI 95%:1.04-3.13, p = 0.034; OR for CKD stage 4: 2.49, CI 95%:1.31-4.70, p = 0.004) and clinical features of congestion (OR:1.51; CI 95%: 1.02-2.25, p = 0.039). On the contrary, males with cardiorenal disease showed higher odds of presenting HF with reduced ejection fraction (HFrEF) (OR:3.13; CI 95%: 1.90-5.16, p < 0.005), ischemic cardiomyopathy (OR:2.17; CI 95%: 1.31-3.61, p = 0.003), hypertension (OR = 2.11; CI 95%:1.18-3.78, p = 0.009), atrial fibrillation (OR:1.71; CI 95%: 1.06-2.75, p = 0.025), and hyperkalemia (OR:2.43, CI 95%: 1.31-4.50, p = 0.005). In this contemporary registry of chronic ambulatory HF patients, we observed sex-related differences in patients with combined heart and kidney disease. The emerging cardiorenal phenotype characterized by advanced CKD, congestion, and HFpEF was predominantly observed in women, whereas HFrEF, ischemic etiology, hypertension, hyperkalemia, and atrial fibrillation were more frequently observed in men.

Safety and Efficacy of the Combination of Sacubitril/Valsartan and SGLT2i in HFrEF Patients (SECSI Registry).

ABSTRACT: Recent studies have proven benefit of SGLT2i drugs in patients with heart failure with reduced ejection fraction (HFrEF), but their safety when combined with angiotensin-neprilysin inhibitor (ARNI) has not been established. The Safety and Efficacy of the Combination of Sacubitril/Valsartan and SGLT2i in HFrEF Patients registry was conducted to address this issue. SECSI registry is a consecutive, observational, retrospective, multicentre study conducted in 3 Heart Failure Units in Spain. It included 144 HFrEF patients who were treated with ARNI and iSGLT2. Data were collected at baseline, month 2, and month 6. The primary endpoint was the estimated glomerular filtration rate (eGFR), after the initiation of ARNI and sodium-glucose cotransporter-2 inhibitors (SGLT2i). Secondary endpoints included potassium levels and functional class (New York Heart Association class). There were 3 prespecified subgroup analyses: Elderly patients (≥70 years), patients with chronic kidney disease (KDIGO classification G3), and the sequence of drug initiation. Mean age was 69.9 ± 10.1 years, and 110 (76.4%) were men. Left ventricular ejection fraction was 32 ± 7.8%, and most patients were symptomatic [123 (87.2%) New York Heart Association II/III/IV]. eGFR decreased at month 2 and this trend was maintained at month 6 [eGFR baseline 68.5 ± 17.3, month 2 62 ± 19.7 and month 6 64.7 ± 8.6 mL/min/1.73 m2 (P < 0.01 for both)]. In prespecified analysis, elder patients and those who simultaneously initiate both treatments showed the steeper decrease in eGFR. To conclude, co-administration of SGLT2i and ARNI in routine care in HFrEF patients produced a slight decrease in eGFR at 6 months of follow-up. This decrease was especially significant in elder patients and those who initiate both drugs simultaneously.

Acute Myopericarditis Associated with Tickborne Rickettsia sibirica mongolitimonae.

We report an unusual case of myopericarditis caused by Rickettsia sibirica mongolitimonae. Because of increasing reports of Rickettsia spp. as etiologic agents of acute myopericarditis and the ease and success with which it was treated in the patient reported here, rickettsial infection should be included in the differential diagnosis for myopericarditis.

Diagnosis and treatment of myocarditis and inflammatory cardiomyopathy. Consensus document of the SEC-Working Group on Myocarditis.

Myocarditis is defined as myocardial inflammation and its etiology is highly diverse, including infectious agents, drugs, and autoimmune diseases. The clinical presentation also varies widely, extending beyond the classic clinical picture of acute chest pain, and includes cases of cardiomyopathy of unknown cause whose etiology may be inflammatory. Because certain patients may benefit from targeted treatments, the search for the etiology should begin when myocarditis is first suspected. There remain several areas of uncertainty in the diagnosis and treatment of this disease. Consequently, this consensus document aims to provide clear recommendations for its diagnosis and treatment. Hence, a diagnostic algorithm is proposed, specifying when non-invasive diagnosis with cardiac MR is appropriate vs a noninvasive approach with endomyocardial biopsy. In addition, more novel aspects are discussed, such as when to suspect an underlying genetic etiology. The recommendations cover the management of myocarditis and inflammatory cardiomyopathy, both for general complications and specific clinical entities.

Prevalence and clinical profile of kidney disease in patients with chronic heart failure. Insights from the Spanish cardiorenal registry.

INTRODUCTION AND OBJECTIVES: Patients with combined heart failure (HF) and chronic kidney disease (CKD) have been underrepresented in clinical trials. The prevalence of CKD in these patients and their clinical profile require constant evaluation. This study aimed to analyze the prevalence of CKD, its clinical profile, and patterns of use of evidence-based medical therapies in HF across CKD stages in a contemporary cohort of ambulatory patients with HF. METHODS: From October 2021 to February 2022, the CARDIOREN registry included 1107 ambulatory HF patients from 13 HF clinics in Spain. RESULTS: The median age was 75 years, 63% were male, and 48% had heart failure with reduced left ventricular ejection fraction (HFrEF). A total of 654 (59.1%) had an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2, and 122 (11%) patients with eGFR ≥ 60 mL/min/1.73 m2 had a urine albumin-creatinin ratio ≥ 30 mg/g. The most important variables associated with lower eGFR were age (R2=61%) and furosemide dose (R2=21%). The proportion of patients receiving an angiotensin-converting enzyme inhibitor (ACEI)/ angiotensin II receptor blockers (ARB), an angiotensin receptor-neprilysin inhibitor (ARNi), a sodium-glucose cotransporter 2 inhibitor (SGLT2i), or a mineralocorticoid receptor antagonist (MRA) progressively decreased with lower eGFR categories. Notably, 32% of the patients with HFrEF and an eGFR <30 mL/min/1.73 m2 received the combination of ACEI/ARB/ARNi+beta-blockers+MRA+SGLT2i. CONCLUSIONS: In this contemporary HF registry, 70% of patients had kidney disease. Although this population is less likely to receive evidence-based therapies, structured and specialized follow-up approaches within HF clinics may facilitate the adoption of these life-saving drugs.

Congestion as a crucial factor determining albuminuria in patients with cardiorenal disease.

Background: Albuminuria could potentially emerge as a novel marker of congestion in acute heart failure. However, the current evidence linking albuminuria and congestion in patients with congestive heart failure (CHF) remains somewhat scarce. This study aimed to evaluate the prevalence of albuminuria in a cohort of patients with CHF, identify the independent factors associated with albuminuria and analyse the correlation with different congestion parameters. Methods: This is a subanalysis of the Spanish Cardiorenal Registry, in which we enrolled 864 outpatients with heart failure and a value of urinary albumin:creatinine ratio (UACR) at the first visit. Results: The median age was 74 years, 549 (63.5%) were male and 438 (50.7%) had a reduced left ventricular ejection fraction. A total of 350 patients (40.5%) had albuminuria. Among these patients, 386 (33.1%) had a UACR of 30-300 mg/g and 64 (7.4%) had a UACR >300 mg/g. In order of importance, the independent variables associated with higher UACR were estimated glomerular filtration rate determined by the Chronic Kidney Disease Epidemiology Collaboration equation (R2 = 57.6%), systolic blood pressure (R2 = 21.1%), previous furosemide equivalent dose (FED; R2 = 7.5%), antigen carbohydrate 125 (CA125; R2 = 6.1%), diabetes mellitus (R2 = 5.6%) and oedema (R2 = 1.9%). The combined influence of oedema, elevated CA125 levels and the FED accounted for 15.5% of the model's variability. Conclusions: In patients with chronic stable heart failure, the prevalence of albuminuria is high. The risk factors of albuminuria in this population are chronic kidney disease and hypertension. Congestion parameters are also associated with increased albuminuria.

Vaccine-carditis study: Spanish multicenter registry of inflammatory heart disease after COVID-19 vaccination.

INTRODUCTION AND OBJECTIVES: Vaccines against SARS-CoV-2 have been a major scientific and medical achievement in the control of the COVID-19 pandemic. However, very infrequent cases of inflammatory heart disease have been described as adverse events, leading to uncertainty in the scientific community and in the general population. METHODS: The Vaccine-Carditis Registry has included all cases of myocarditis and pericarditis diagnosed within 30 days after COVID-19 vaccination since August 1, 2021 in 29 centers throughout the Spanish territory. The definitions of myocarditis (probable or confirmed) and pericarditis followed the consensus of the Centers for Disease Control and the Clinical Practice Guidelines of the European Society of Cardiology. A comprehensive analysis of clinical characteristics and 3-month evolution is presented. RESULTS: From August 1, 2021, to March 10, 2022, 139 cases of myocarditis or pericarditis were recorded (81.3% male, median age 28 years). Most cases were detected in the 1st week after administration of an mRNA vaccine, the majority after the second dose. The most common presentation was mixed inflammatory disease (myocarditis and pericarditis). 11% had left ventricular systolic dysfunction, 4% had right ventricular systolic dysfunction, and 21% had pericardial effusion. In cardiac magnetic resonance studies, left ventricular inferolateral involvement was the most frequent pattern (58%). More than 90% of cases had a benign clinical course. After a 3-month follow-up, the incidence of adverse events was 12.78% (1.44% mortality). CONCLUSIONS: In our setting, inflammatory heart disease after vaccination against SARS-CoV-2 predominantly affects young men in the 1st week after the second dose of RNA-m vaccine and presents a favorable clinical course in most cases.

Importance of genetic study in elderly patients with transthyretin cardiac amyloidosis. / Relevancia del estudio genético de la amiloidosis cardíaca por transtiretina en el anciano.

BACKGROUND AND OBJECTIVE: Cardiac transthyretin amyloidosis (CA-ATTR) is a prevalent disease with age. Genetic study is recommended, even in eldest patients. We aim to analyze the prevalence of hereditary transthyretin amyloidosis (ATTRv) in elderly patients (≥75years) with CA-ATTR and its implications. PATIENTS AND METHODOLOGY: Retrospective observational study of the cohort of elderly patients with CA-ATTR diagnosed according to the international recommended protocol. We analyze the results of sequencing TTR gene, the differential characteristics and their clinical implications. RESULTS: Between 2016 and 2022, 130 elderly patients (89% cohort) were diagnosed with CA-ATTR (85% male). In 8 of the 123 patients with a genetic study, a pathogenic variant in TTR was identified (6.5%), initiating specific treatment in 4 subjects (50%). The family study identified another case and 6 asymptomatic carriers. There were no significant differences between baseline characteristics or in clinical events. CONCLUSIONS: The prevalence of ATTRv in elderly patients with CA-ATTR was 6.5% without observing differential characteristics that allow guiding a selective indication of genetic analysis.
