RESUMO
Angiotensin receptor-neprilysin inhibitors (ARNI) are effective against heart failure (HF) with reduced ejection fraction, but hypotension is a significant complication. Predictors of ARNI-associated hypotension remain unclear. This study aimed to determine predictors of hypotension after administering an ARNI to patients with HF accompanied by ARNI.This retrospective multicenter observational study analyzed data from 138 consecutive patients with HF treated with an ARNI between August 2020 and July 2021. Hypotension attributed to an ARNI after treatment was defined as (A) systolic blood pressure (SBP) below the 1st quartile ≤ 25 mmHg, and as (B) absolute SBP ≤ 103 mmHg. SBP was measured at baseline, after ARNI treatment, at first follow-up as outpatients and on day 7 for inpatients. Presence of atrial fibrillation, and greater BUN/Cr ratio, and SBP at baseline were significant independent predictors for hypotension after ARNI administration on multivariate analyses. Among 43 patients with AF, fine f-waves on electrocardiograms were significantly more prevalent in the hypotensive group.A robust reduction in blood pressure after ARNI administration is associated with AF and elevated BUN/Cr. This highlights the need for caution when administering ARNI to patients with HF.

Angiotensin II receptor blockers (ARBs) are contraindicated during pregnancy because of fetal toxicity. All previous reports on adverse fetal outcomes involved women who continued to take low-dose ARBs for hypertension and were unaware of the adverse effects. Herein, we report the case of a 23-year-old pregnant woman in her third trimester who experienced an ARB overdose after an argument with her partner. Pregnancy was complicated by transient oligohydramnios, and fetal magnetic resonance imaging suggested renal failure. Despite these concerns, the newborn had no morphological abnormalities or abnormal neurological findings. Renal impairment improved over time, and the infant grew well. A single overdose of ARBs in the third trimester can lead to fetal renal failure, similar to long-term low-dose ARB administration; however, favorable outcomes are possible. An overdose of ARBs may transiently cause renal failure, which may improve. The study findings may inform counseling for women who are unexpectedly exposed to an overdose of ARBs.

Acne vulgaris is a common chronic dermatological condition characterized by obstruction and inflammation of pilosebaceous units. Recent research on a different dermatologic condition has demonstrated that the use of vasodilatory medications is associated with a decreased relative risk of rosacea. This finding is significant due to the overlapping inflammatory pathways involved in rosacea and acne. Herein, a retrospective cohort study was designed to determine the correlation between vasodilator usage and the risk of developing acne within 5 years, contrasting it with thiazide diuretics, chosen as a control due to its non-vasodilatory antihypertensive mechanism and availability of data. Angiotensin-converting enzyme (ACE) inhibitors (RR, 0.775; 95% CI, 0.727-0.826; P<0.05), angiotensin receptor blockers (ARBs) (RR, 0.739; 95% CI, 0.685-0.797; P<0.05), beta-blockers (BB) (RR, 0.829; 95% CI, 0.777-0.885; P<0.05), and calcium channel blockers (CCB) usage (RR, 0.821, 95% CI, 0.773-0.873; P<0.05) were associated with a significantly lower risk of developing acne within 5 years of initiating therapy compared to thiazide diuretics. It is unclear if thiazide diuretics are more likely to cause acne within the adult population or if vasodilators are protective against the development of acne. Finding mechanisms and therapeutics that lower the risk of developing acne is of significant public health interest, and this study provides a step toward this endeavor. Further research is required to uncover the underlying mechanisms for this reduction in the development of acne. J Drugs Dermatol. 2024;23(6):446-449. doi:10.36849/JDD.8362.

Background: Peripartum cardiomyopathy (PPCM) is a common cause of heart failure (HF) in the peripartum. Some medications are considered safe while breastfeeding. However, sacubitril/valsartan (Entresto), while efficacious, is not recommended in breastfeeding women due to concerns about adverse infant development, and no published data suggest otherwise. Objectives: This study aimed to assess the transfer of sacubitril/valsartan into human milk and evaluate the infant's risk of drug exposure. Methods: The InfantRisk Human Milk Biorepository released samples and corresponding health information from five breastfeeding maternal-infant dyads exposed to sacubitril/valsartan. Sacubitril, valsartan, and LBQ657 (sacubitril active metabolite) concentrations were determined using liquid chromatography-mass spectrometry (LC/MS/MS) from timed samples 0, 1, 2, 4, 6, 8, 10, and 12 h following medication administration at steady state conditions. Results: Valsartan levels were below the detection limit of 0.19 ng/mL in all milk samples. Sacubitril was measurable in all milk samples of the five participants, peaking 1 h after drug administration at a mean concentration of 1.52 ng/mL for a total infant dose of 0.00049 mg/kg/12 h and a relative infant dose (RID) calculated at 0.01%. The maximum concentration of its active metabolite LBQ657 in the milk samples was observed 4 h after medication administration and declined over the remaining 12-h dosing interval, for an average concentration of 9.5 ng/mL. The total infant dose was 0.00071 mg/kg/12 h, and the RID was 0.22%. Two mothers reported continuing to breastfeed while taking sacubitril/valsartan; both mothers stated observing no negative effects in their breastfed infants. Conclusion: The transfer of sacubitril/valsartan into human milk is minimal. These concentrations are unlikely to pose a significant risk to breastfeeding infants, with a combined calculated RID of <0.25%, which is far lower than the industry safety standards (RID <10%).

Cancer therapy-related cardiac dysfunction (CTRCD) is a complication of selected cancer therapy agents associated with decline in left ventricular ejection fraction (LVEF). Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) have established benefits in heart failure with reduced ejection fraction, but their efficacy for preventing CTRCD remains controversial. This narrative systematic review assessed the efficacy and safety of ACEI/ARB in the prevention of cancer therapy LVEF decline. We systematically searched PubMed, Embase and Cochrane from January 1980 to June 2022. Studies of interest were randomised controlled trials of patients with normal LVEF and active malignancy receiving cancer therapy, randomised to receive either an ACEI or ARB compared with a control group. The outcome was the change in LVEF from baseline to the end of the follow-up period. Death, clinical heart failure and adverse drug reactions were recorded. A total of 3731 search records were screened and 12 studies were included, comprising a total of 1645 participants. Nine studies assessed the prevention of anthracycline-induced LVEF decline, of which five showed a beneficial effect (1%-14% higher LVEF in treated groups), whereas four studies showed no effect. Three studies assessed the prevention of trastuzumab-induced LVEF decline, of which one showed a beneficial effect (4% higher LVEF) in a subset of participants. There are mixed data regarding the efficacy of ACEI/ARB in preventing the LVEF decline in patients undergoing anthracycline or trastuzumab therapy, with evidence suggesting no clinically meaningful benefit observed in recent studies.

AIMS: Guidelines recommend target doses (TD) of heart failure (HF) with reduced ejection fraction (HFrEF) medications regardless of sex. Differences in pharmacokinetics and pharmacodynamics may explain heterogeneity in treatment response, adverse reactions, and tolerability issues across sexes. The aim of this study was to explore sex-based differences in the association between TD achievement and mortality/morbidity in HFrEF. METHODS AND RESULTS: Patients with HFrEF and HF duration ≥6 months registered in the Swedish HF Registry between May 2000 and December 2020 (follow-up until December 2021) were analysed. Treatments of interest were renin-angiotensin system inhibitors (RASI) or angiotensin receptor-neprilysin inhibitors (ARNI), and beta-blockers. Multivariable Cox regression models were performed to explore the risk of cardiovascular mortality or hospitalization for HF across dose categories in females versus males. A total of 17 912 patients were analysed (median age 77.0 years, interquartile range [IQR] 70.0-83.0), 29% were female. Over a median follow-up of 1.33 years (IQR 0.29-3.22), for RASI/ARNI there was no significant difference in outcome for females achieving 50-99% versus 100% of TD (hazard ratio 0.92, 95% confidence interval 0.83-1.03), whereas males showed a gradual lowering in risk together with the achievement of higher % of TD (p-interaction = 0.030). For beta-blockers the achievement of TD was associated with the lowest risk of outcome regardless of sex. CONCLUSIONS: Our findings suggest that females and males might differently benefit from the same dose of RASI/ARNI, and do represent a general call for randomized controlled trials to consider sex-specific up-titration schemes when testing HFrEF treatments in need of up-titration.

Cardiovascular outcome in Marfan syndrome (MFS) patients most prominently depends on aortic aneurysm progression with subsequent aortic dissection. Angiotensin II receptor blockers (ARBs) prevent aneurysm formation in MFS mouse models. In patients, ARBs only slow down aortic dilation. Downstream signalling from the angiotensin II type 1 receptor (AT1R) is mediated by G proteins and ß-arrestin recruitment. AT1R also interacts with the monocyte chemoattractant protein-1 (MCP-1) receptor, resulting in inflammation. In this study, we explore the targeting of ß-arrestin signalling in MFS mice by administering TRV027. Furthermore, because high doses of the ARB losartan, which has been proven beneficial in MFS, cannot be achieved in humans, we investigate a potential additive effect by combining lower concentrations of losartan (25 mg/kg/day and 5 mg/kg/day) with barbadin, a ß-arrestin blocker, and DMX20, a C-C chemokine receptor type 2 (CCR2) blocker. A high dose of losartan (50 mg/kg/day) slowed down aneurysm progression compared to untreated MFS mice (1.73 ± 0.12 vs. 1.96 ± 0.08 mm, p = 0.0033). TRV027, the combination of barbadin with losartan (25 mg/kg/day), and DMX-200 (90 mg/kg/day) with a low dose of losartan (5 mg/kg/day) did not show a significant beneficial effect. Our results confirm that while losartan effectively halts aneurysm formation in Fbn1C1041G/+ MFS mice, neither TRV027 alone nor any of the other compounds combined with lower doses of losartan demonstrate a notable impact on aneurysm advancement. It appears that complete blockade of AT1R function, achieved by administrating a high dosage of losartan, may be necessary for inhibiting aneurysm progression in MFS.

AIMS: The effects of initiating sacubitril/valsartan in patients with stable heart failure with reduced ejection fraction (HFrEF) on response to fluid and sodium expansion are unknown. METHODS AND RESULTS: We have explored changes in natriuresis, diuresis, and congestion in response to the administration of intravenous fluid/sodium load in patients with HFrEF before as compared to after the initiation of sacubitril/valsartan. At baseline (before sacubitril/valsartan initiation) and 2 and 3 months after the initiation, patients underwent an evaluation that consisted of three phases of 3 h: the rest phase (0-3 h), the load phase (3-6 h) in which 1 L of intravenous Ringer solution was administered, and the diuretic phase (6-9 h) at the beginning of which furosemide was administered. Overall, 216 patients completed the study. In comparison to baseline values, at 2 and 3 months after sacubitril/valsartan initiation, patients' diuresis and natriuresis in response to Ringer administration significantly increased (mean difference: 38.8 [17.38] ml, p = 0.0040, and 9.6 [2.02] mmol, p < 0.0001, respectively). Symptoms and signs of congestion after the fluid/sodium challenge were significantly decreased at months 2 and 3 compared to baseline. Compared to baseline, there was also an increment of natriuresis after furosemide administration on sacubitril/valsartan (9.8 [5.13] mmol, p = 0.0167). There was a significant decrease in body weight in subsequent visits when compared to baseline values (-0.50 [-12.7, 7.4] kg at 2 months, and -0.75 [-15.9, 7.5] kg at 3 months; both p < 0.0001). CONCLUSIONS: The initiation of sacubitril/valsartan in HFrEF patients was associated with improvements in natriuresis, diuresis, and weight loss and better clinical adaptation to potentially decongestive stressors.

PURPOSE: The objective of this meta-analysis is to determine how sacubitril/valsartan (SV) compares to equivalent and sub-equivalent angiotensin receptor blockers (ARB) or angiotensin-converting enzyme inhibitors (ACEI) in patients with heart failure with reduced ejection fraction (HFrEF). METHODS: The databases of PubMed and EMBASE were used to identify those randomized controlled trials which compared SV to ARB/ACEI in patients with HFrEF. Only those trials that reported outcomes regarding total mortality, cardiovascular mortality, and worsening heart failure were considered. Meta-analysis was performed separately in those patients receiving equivalent doses of ARB/ACEI and those receiving sub-equivalent doses. Equivalent doses were SV 97/103 = valsartan 160 mg twice daily = enalapril 20 mg twice daily = ramipril 5 mg twice daily. Meta-analyses were performed using Review Manager 5.4. RESULTS: Twelve randomized trials were identified involving 17,484 patients: 11,291 in the sub-equivalent group (8 trials) and 6193 in the equivalent group (4 trials). Meta-analyses showed there were no statistical differences regarding the outcomes of total mortality, cardiovascular mortality, and worsening heart failure in the equivalent dosing group. However, SV reduced total mortality (risk ratio (RR) = 0.85, 95% confidence interval (CI) = 0.78-0.93, p < 0.001), cardiovascular mortality (RR = 0.81, 95% CI = 0.73-0.90, p ≤ 0.001) and worsening heart failure (RR = 0.77, 95% CI = 0.64-0.92, p = 0.005) in the sub-equivalent group. CONCLUSION: When compared to equivalent doses of ARB/ACEI, SV is not superior in reducing mortality and worsening heart failure. SV is superior when compared to sub-equivalent doses of ACEI.

Effects of angiotensin receptor/neprilysin inhibitors (ARNI) on ventricular remodeling in patients with heart failure, especially heart failure with reduced ejection fraction (HFrEF), are better than those of angiotensin-converting enzyme inhibitors (ACEI). Acute myocardial infarction (AMI) complicated by mitral regurgitation exacerbates ventricular remodeling and increases the risk of heart failure. There is limited evidence on the effects of early administration of ARNI in patients with AMI complicated by mitral regurgitation. The aim of this trial was to examine the effectiveness and the safety of early administration of sacubitril/valsartan after coronary artery revascularization in patients with AMI complicated by moderate-to-severe mitral regurgitation. This was a randomized, single-blind, parallel-group, controlled trial. From June 2021 to June 2022, we enrolled 142 consecutive patients with AMI complicated by moderate-to-severe mitral regurgitation and followed them for 12 months. The patients received standard treatment for AMI and were randomly assigned to receive ARNI or benazepril. The primary efficacy end points were the differences in mitral regurgitant jet area (MRJA), mitral regurgitant volume (MRV), concentration of n-terminal pro-brain natriuretic peptide (NT-proBNP), left ventricular ejection fraction (LVEF), and left ventricular end-diastolic volume and end-systolic volume (LVEDV and LVESV) between groups and within groups at baseline, 1, 3, 6, and 12 months. Secondary end points included the rates of heart failure hospitalization, all-cause mortality, refractory angina, malignant arrhythmias, recurrent myocardial infarction, and stroke. Safety end points included the rates of hyperkalemia, renal dysfunction, hypotension, angioedema, and cough. The ARNI group had significantly lower NT-proBNP levels than the benazepril group at 1 month and later (P < 0.001). MRJA and MRV significantly improved in the ARNI group compared with the benazepril group at 12 months (MRJA: - 3.21 ± 2.18 cm2 vs. - 1.83 ± 2.81 cm2, P < 0.05; MRV: - 27.22 ± 15.22 mL vs. - 13.67 ± 21.02 mL, P < 0.001). The ARNI group also showed significant reductions in LVEDV and LVESV (P < 0.05) and improvement in LVEF (P < 0.05). Secondary end point analysis showed a significantly higher rate of heart failure hospitalization in the benazepril group compared with the ARNI group (HR = 2.03, 95% CI 1.12-3.68, P = 0.021). Safety end point analysis showed a higher rate of hypotension in the ARNI group (P < 0.05). Early use of sacubitril/valsartan after coronary artery revascularization in patients with AMI complicated by moderate-to-severe mitral regurgitation can significantly reduce mitral regurgitation, improve ventricular remodeling, and decrease heart failure hospitalization. Nevertheless, caution is needed to avoid hypotension. Chinese Clinical Trial Registry (ChiCTR2100054255) registered on December 11, 2021.

Elevated blood pressure (BP) is the largest contributor to the incident cardiovascular disease worldwide. Despite explicit guideline recommendations for the diagnosis and management of hypertension, a large proportion of patients remain undiagnosed, untreated, or treated but uncontrolled. Inadequate BP control is associated with many complex factors including patient preference, physician's inertia, health systems disparities, and poor adherence to prescribed antihypertensive drug treatment. The primary driver for reduced cardiovascular morbidity and mortality is lowering of BP ''per se'' and not class effects of specific pharmacotherapies. The recent ESH guidelines recommend the use of four major classes of drugs including renin-angiotensin-aldosterone system (RAS) blockers (angiotensin receptor blockers (ARB) or angiotensin-converting enzyme inhibitors (ACEi)), calcium channel blockers (CCB), thiazide and thiazide-like diuretics, and betablockers. Initiation of treatment for hypertension with a two-drug regimen, preferably in a single pill combination (SPC), is recommended for most patients. Preferred combinations should comprise a RAS blocker (either an ACEi or an ARB) with a CCB or thiazide/thiazide-like diuretic. These strategies are supported by robust evidence that combination therapy produces greater BP reductions than monotherapy, reduces side effects of the individual components, improves therapeutic adherence and long-term persistence on treatment, and permits achievement of earlier BP control.

BACKGROUND: Hypotension is a potential adverse effect of sacubitril/valsartan, but there are limited data regarding the predictors and implications of treatment-related hypotension in heart failure (HF) with mildly reduced and preserved ejection fraction. OBJECTIVES: We investigated predictors of treatment-associated hypotension, clinical outcomes after hypotension, and the relationship between left ventricular ejection fraction (LVEF) and incidence of hypotension in the PARAGON-HF (Prospective Comparison of ARNI with ARB Global Outcomes in HF with Preserved Ejection Fraction) trial. METHODS: PARAGON-HF randomized patients with chronic HF (≥45%) to sacubitril/valsartan or valsartan. Following randomization, hypotension was defined as investigator-reported hypotension with a systolic blood pressure <100 mm Hg. Predictors of hypotension were assessed using multivariable Cox models. Associations between hypotension and clinical outcomes were evaluated in time-updated Cox models. The relationship among treatment, LVEF, and incident rates of hypotension and clinical outcomes was estimated using Poisson regression models. RESULTS: Of 4,796 patients in PARAGON-HF, 637 (13%) experienced hypotension, more frequently in the sacubitril/valsartan arm (P < 0.001). Following documented hypotension, patients had higher risk of cardiovascular death and total HF hospitalizations (adjusted RR: 1.63; 95% CI: 1.27-2.09; P < 0.001) and all-cause death (adjusted HR: 1.62; 95% CI: 1.28-2.05; P < 0.001). LVEF modified the association between sacubitril/valsartan and risk of hypotension (Pinteraction = 0.019) such that patients with LVEF ≥60% experienced substantially higher treatment-related risks of hypotension. CONCLUSIONS: In PARAGON-HF, a higher LVEF was associated with an increased risk of hypotension in patients treated with sacubitril/valsartan compared with valsartan. Because these subjects are also less likely to derive clinical benefit from sacubitril/valsartan, our data reinforce that the benefit/risk ratio favors the use of sacubitril/valsartan in patients with LVEF below normal, but not at higher LVEF.

AIMS: Cardiac resynchronization therapy (CRT) is an established treatment for drug-refractory heart failure (HF) in patients with left bundle branch block (LBBB). Acute haemodynamic improvement after CRT implantation may enable the intensification of HF medication soon thereafter. Immediate pharmacotherapy intensification (IPI) after CRT implantation achieves a synergetic effect, possibly leading to a better prognosis. This study aimed to explore the incidence, characteristics, and impact of IPI on real-world outcomes among CRT recipients with a history of hospitalization for acute HF. METHODS AND RESULTS: This multicentre retrospective study enrolled CRT recipients with LBBB morphology, a QRS width ≥120 ms, a left ventricular ejection fraction ≤35%, and New York Heart Association II-IV HF symptoms. All patients had previous HF hospitalizations within the previous year and received guideline-directed medical therapy before CRT implantation. Patient baseline characteristics, including HF medication, were collected. IPI was defined as the intensification of beta-blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and mineralocorticoid receptor antagonists within 30 days of CRT implantation. The primary endpoint was all-cause death or first hospitalization for HF; the secondary endpoint was all-cause death. We enrolled 194 patients (75% male; mean age, 65 ± 13 years; 78% with non-ischaemic cardiomyopathy). One hundred five (54%) patients received IPI. Patients who received IPI exhibited a significantly shorter QRS duration (159 ± 26 vs. 171 ± 32 ms; P = 0.004), higher estimated glomerular filtration rate (55.2 ± 20.0 vs. 47.8 ± 24.7 mL/min/1.73 m2; P = 0.022), and more dilated cardiomyopathy. During a median follow-up period of 29 months, 70 (36%) patients reached the primary endpoint and 42 (22%) patients died. Patients with IPI showed significantly better outcomes for the primary and secondary endpoints than patients without IPI. The volumetric responder ratio at 6 months after implantation was not significantly different between patients with and without IPI; however, patients who received IPI had reduced mortality even at 6 months after implantation. In the multivariate analysis, IPI was an independent predictor of the primary endpoint (hazard ratio, 0.51; 95% confidence interval, 0.27-0.97; P = 0.043). CONCLUSIONS: Immediate intensification of HF medication was achieved in 54% of CRT recipients and was significantly higher in patients without excessive QRS prolongation, preserved renal function, and dilated cardiomyopathy than others. In patients with LBBB morphology and QRS ≥ 120 ms, IPI was associated with a significantly better prognosis and fewer HF hospitalizations after CRT implantation than others.

INTRODUCTION: Results on the association between the use of renin-angiotensin system blockades (RASBs) and vascular access-related outcomes are inconsistent. We aimed to compare vascular access-related outcomes according to the use of RASBs in hemodialysis patients. METHODS: This study used data from a national hemodialysis quality assessment program of the Republic of Korea (n = 54,903). Group 1 was not prescribed any blood pressure-lowering drugs (n = 28,521). Group 2 was prescribed other blood pressure-lowering agents except for RASBs (n = 9571). Group 3 was prescribed RASBs (n = 16,811). Vascular access-related outcomes were classified into intervention-free survival (IFS), thrombosis-free survival (TFS), and vascular access survival (VAS). RESULTS: No significant difference in the three access survival rates was identified among the three groups. The multivariate Cox regression analyses indicated that Group 3 had better outcomes in IFS and TFS than Group 1. The numbers of angioplasties performed were significantly greater in Group 1 than in the other two groups. The numbers of thrombectomies performed were significantly the lowest in Group 3 among all the groups. CONCLUSIONS: Our study revealed different results according to types of access survival in univariate or multivariate analyses. The association of RASBs with favorable outcomes in vascular access remains unclear.

Abstract As severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected patients with hypertension and other cardiovascular comorbidities develop more severe coronavirus disease (COVID)-19 and are at high risk of death, a controversy arose about the use of antihypertensives as angiotensin-converting enzyme inhibitors (ACEis) and angiotensin II receptor blockers (ARBs). Such drugs might increase the expression of the fundamental receptor of this new infectious agent: the angiotensin-converting enzyme 2 (ACE2). Preclinical observations indicate that the increase of ACE2 expression or the activity by ACEis and ARBs leads to a greater transformation of angiotensin (Ang)-II to Ang-(1-7), which is associated with positive effects on cardiovascular and pulmonary pathophysiology. This association has been demonstrated in observational studies in patients with cardiovascular pathology and pneumonia. It has not been possible to confirm whether users of ACEis or ARBs are more infected by the new coronavirus, due to methodological issues in studies with patients infected with SARS-CoV-2. However, the use of such antihypertensive treatments in both children and adults might reduce the virulence of infection. Therefore, changes in the antihypertensive therapy of patients at risk of contracting COVID-19 are not recommended.
Resumen Los pacientes con hipertensión y otra comorbilidad cardiovascular infectados con SARS-CoV-2 desarrollan cuadros más graves de COVID-19 y con mayor frecuencia fallecen. Este hecho ha originado una controversia acerca del uso de antihipertensivos inhibidores de la enzima convertidora de la angiotensina (IECA) y de antagonistas de los receptores de la angiotensina II (ARA-II), pues tales medicamentos pueden incrementar la expresión del receptor funcional de este nuevo agente infeccioso: la enzima convertidora de la angiotensina 2 (ECA2). Las observaciones preclínicas indican que el aumento de la expresión o de la actividad de la ECA2 por uso de IECA o ARA-II conduce a una mayor transformación de angiotensina 2 a a angiotensina 1-7, la cual se asocia con efectos positivos sobre la fisiopatología pulmonar y cardiovascular. En estudios observacionales de pacientes con patología cardiovascular y neumonía se ha confirmado esta asociación. La falta de evidencia contundente debida a aspectos metodológicos en estudios con pacientes infectados con SARS-CoV-2 no permite confirmar si los usuarios de IECA o ARA-II se contagian más con el nuevo coronavirus. Sin embargo, continuar con tales medicamentos antihipertensivos, tanto en adultos como en niños, podría reducir la virulencia de la infección. Por ello, no se recomienda cambiar la terapia antihipertensiva en los pacientes susceptibles a la COVID-19.

Background: Pharmacological treatment improves survival in patients with heart failure with reduced ejection fraction. The use of sacubutril/valsartan and ivabradine has been recently approved and incorporated in the latest guidelines. Aim: To identify candidates eligible for these therapies among patients treated in a heart failure clinic, considering the inclusion criteria for the PARADIGM-HF and SHIFT trials. Material and Methods: Cross-sectional study on 158 patients aged 62 ± 11 years (67% male) with heart failure and reduced ejection fraction, with at least three months of follow-up and without decompensation. The percentage of patients complying for the inclusion criteria for the PARADIGM-HF y SHIFT trials was determined. Results: In 37%, the etiology of heart failure was ischemic, 49% were in functional class I, their ejection fraction was 33 ± 11% and their median Pro-brain natriuretic peptide was 800 pg/mL. Ninety five percent were treated with vasodilators, 97% with beta-blockers and 82% with aldosterone antagonists. Using PARADIGM-HF and SHIFT criteria, 11 patients (7%) were eligible for sacubitril / valsartan and 21 patients (13.3%) for ivabradine. Among the main causes of non-eligibility for sacubitril / valsartan were being functional class I (48.7%) and not achieving a stable dose of enalapril ≥ 20 mg / day or losartan ≥ 100 mg / day (24.7%). In the case of ivabradine, apart from those in functional class I, the absence of sinus rhythm and a heart rate < 70 / min when receiving a maximal tolerated dose of beta-blockers, were present in 22%. Conclusions: A low percentage of our patients were eligible for these therapies. Among the causes that explain these results were clinical stability, a high percentage of patients in functional class I and being in a disease modifying treatment.

Introducción: La HTA es una enfermedad crónica caracterizada por un aumento sostenido en los niveles de la TA normal. La cronicidad de la HTA afecta otras estructuras anatómicas siendo un factor de riesgo para el desarrollo de varias enfermedades. Sin embargo, a pesar de contar con varias opciones terapéuticas, determinar su efectividad comparativa y escoger la terapia antihipertensiva es difícil, ya que la selección de ésta puede estar influenciado por muchas variables y por la amplia gama de terapia que está disponible. Objetivo: Evaluar la efectividad y seguridad de la combinación de los ARA II con CA o diuréticos, comparados entre sí para el tratamiento de pacientes con HTA. Metodología: se realizó una evaluación crítica a través de una búsqueda sistemática en bases de datos electrónicas, diseñadas con vocabulario controlado y no controlado, además, de indagar con expertos sobre la disponibilidad de estudios publicados y no publicados, en inglés y español, la tamización de los resultados fue llevada a cabo por 2 revisores expertos. Los hallazgos de efectividad y seguridad fueron extraídos de los estudios con mejor calidad metodológica, buscando obtener información para todas las comparaciones y desenlaces de interés. Resultados: La combinación telmisartán/diurético, mostró una mayor reducción de la TA que la combinación de otros ARA II con diurético (-2.91 mmHg, IC 95% -3.66, -2.15). La triple terapia es más efectiva que la terapia dual (OR 1.86, IC 95% 1.69, 2.04) para alcanzar TA controladas. Conclusiones: En términos de reducción de la TA tanto sistólica como diastólica la evidencia hallada no encuentra diferencias significativas entre la combinacion de losartán/calcio antagonistas, y valsartán/calcio antagonistas a diferentes dosis pero si una diferencia entre la combinación telmisartán/diurético comparado contra olmesartán, ó valsartán ó losartán combinado con diurético. Asi mismo, la terapia de triple combinación es más efectiva que la terapia dual. Seguridad: No se hallaron comparaciones de seguridad entre terapia dual. Sin embargo, la combinación de los tres tipos de fármacos no se asoció con un exceso de riesgo frente a la terapia dual.(AU)
