Physiology of exercise and heart failure treatments: cardiopulmonary exercise testing as a tool for choosing the optimal therapeutic strategy.

In the last decades, the pharmacological treatment of heart failure (HF) become more complex due to the availability of new highly effective drugs. Although the cardiovascular effects of HF therapies have been extensively described, less known are their effects on cardiopulmonary function considered as a whole, both at rest and in response to exercise. This is a 'holistic' approach to disease treatment that can be accurately evaluated by a cardiopulmonary exercise test. The aim of this paper is to assess the main differences in the effects of different drugs [angiotensin-converting enzyme (ACE)-inhibitors, Angiotensin II receptor blockers, ß-blockers, Angiotensin receptor-neprilysin inhibitors, renal sodium-glucose co-transporter 2 inhibitors, iron supplementation] on cardiopulmonary function in patients with HF, both at rest and during exercise, and to understand how these differences can be taken into account when choosing the most appropriate treatment protocol for each individual patient leading to a precision medicine approach.

Slowing the Progression of Diabetic Kidney Disease.

Diabetes is the most frequent cause of kidney disease that progresses to end-stage renal disease worldwide, and diabetic kidney disease is significantly related to unfavorable cardiovascular outcomes. Since the 1990s, specific therapies have emerged and been approved to slow the progression of diabetic kidney disease, namely, renin-angiotensin-aldosterone system blockers (including angiotensin-converting enzyme inhibitors (ACEi) angiotensin receptor blockers (ARBs), the non-steroidal mineralocorticoid receptor antagonist (NS-MRA), finerenone, and sodium-glucose cotransporter-2 (SGLT2) inhibitors). Mechanistically, these different classes of agents bring different anti-inflammatory, anti-fibrotic, and complementary hemodynamic effects to patients with diabetic kidney disease such that they have additive benefits on slowing disease progression. Within the coming year, there will be data on renal outcomes using the glucagon-like peptide-1 receptor agonist, semaglutide. All the aforementioned medications have also been shown to improve cardiovascular outcomes. Thus, all three classes (maximally dosed ACEi or ARB, low-dose SGLT-2 inhibitors, and the NS-MRA, finerenone) form the "pillars of therapy" such that, when used together, they maximally slow diabetic kidney disease progression. Ongoing studies aim to expand these pillars with additional medications to potentially normalize the decline in kidney function and reduce associated cardiovascular mortality.

Effects of sacubitril/valsartan on exercise capacity: a prognostic improvement that starts during uptitration.

PURPOSE: Sacubitril/valsartan is a mainstay of the treatment of heart failure with reduced ejection fraction (HFrEF); however, its effects on exercise performance yielded conflicting results. Aim of our study was to evaluate the impact of sacubitril/valsartan on exercise parameters and echocardiographic and biomarker changes at different drug doses. METHODS: We prospectively enrolled consecutive HFrEF outpatients eligible to start sacubitril/valsartan. Patients underwent clinical assessment, cardiopulmonary exercise test (CPET), blood sampling, echocardiography, and completed the Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Sacubitril/valsartan was introduced at 24/26 mg b.i.d. dose and progressively uptitrated in a standard monthly-based fashion to 97/103 mg b.i.d. or maximum tolerated dose. Study procedures were repeated at each titration visit and 6 months after reaching the maximum tolerated dose. RESULTS: Ninety-six patients completed the study, 73 (75%) reached maximum sacubitril/valsartan dose. We observed a significant improvement in functional capacity across all study steps: oxygen intake increased, at peak exercise (from 15.6 ± 4.5 to 16.5 ± 4.9 mL/min/kg; p trend = 0.001), while minute ventilation/carbon dioxide production relationship reduced in patients with an abnormal value at baseline. Sacubitril/valsartan induced positive left ventricle reverse remodeling (EF from 31 ± 5 to 37 ± 8%; p trend < 0.001), while NT-proBNP reduced from 1179 [610-2757] to 780 [372-1344] pg/ml (p trend < 0.0001). NYHA functional class and the subjective perception of limitation in daily life at KCCQ-12 significantly improved. The Metabolic Exercise Cardiac Kidney Index (MECKI) score progressively improved from 4.35 [2.42-7.71] to 2.35% [1.24-4.96], p = 0.003. CONCLUSIONS: A holistic and progressive HF improvement was observed with sacubitril/valsartan in parallel with quality of life. Likewise, a prognostic enhancement was observed.

Pharmacotherapy of heart failure A.D. 2023. Expert opinion of Working Group on Cardiovascular Pharmacotherapy, Polish Cardiac Society.

Heart failure (HF) remains one of the most common causes of hospitalization and mortality among Polish patients. The position of the Section of Cardiovascular Pharmacotherapy presents the currently applicable options for pharmacological treatment of HF based on the latest European and American guidelines from 2021-2022 in relation to Polish healthcare conditions. Treatment of HF varies depending on its clinical presentation (acute/chronic) or left ventricular ejection fraction. Initial treatment of symptomatic patients with features of volume overload is based on diuretics, especially loop drugs. Treatment aimed at reducing mortality and hospitalization should include drugs blocking the renin-angiotensin-aldosterone system, preferably angiotensin receptor antagonist/neprilysin inhibitor, i.e. sacubitril/valsartan, selected beta-blockers (no class effect - options include bisoprolol, metoprolol succinate, or vasodilatory beta-blockers - carvedilol and nebivolol), mineralocorticoid receptor antagonist, and sodium-glucose cotransporter type 2 inhibitor (flozin), constituting the 4 pillars of pharmacotherapy. Their effectiveness has been confirmed in numerous prospective randomized trials. The current HF treatment strategy is based on the fastest possible implementation of all four mentioned classes of drugs due to their independent additive action. It is also important to individualize therapy according to comorbidities, blood pressure, resting heart rate, or the presence of arrhythmias. This article emphasizes the cardio- and nephroprotective role of flozins in HF therapy, regardless of ejection fraction value. We propose practical guidelines for the use of medicines, profile of adverse reactions, drug interactions, as well as pharmacoeconomic aspects. The principles of treatment with ivabradine, digoxin, vericiguat, iron supplementation, or antiplatelet and anticoagulant therapy are also discussed, along with recent novel drugs including omecamtiv mecarbil, tolvaptan, or coenzyme Q10 as well as progress in the prevention and treatment of hyperkalemia. Based on the latest recommendations, treatment regimens for different types of HF are discussed.

Holistic approach to drug therapy in a patient with heart failure.

Heart failure (HF) is a growing global public health problem affecting at least 26 million people worldwide. The evidence-based landscape for HF treatment has changed at a rapid rate over the last 30 years. International guidelines for the management of HF now recommend the use of four pillars in all patients with reduced ejection fraction: angiotensin receptor neprilysin inhibitors or ACE inhibitors, beta blockers, mineralocorticoid receptor antagonists and sodium-glucose co-transporter-2 inhibitors. Beyond the main four pillar therapies, numerous further pharmacological treatments are also available in specific patient subtypes. These armouries of drug therapy are impressive, but where does this leave us with individualised and patient-centred care? This paper reviews the common considerations needed to provide a holistic, tailored and individual approach to drug therapy in a patient with HF with reduced ejection fraction, including shared decision making, initiating and sequencing of HF pharmacotherapy, drug-related considerations, polypharmacy and adherence.

Latest Knowledge on the Role of Vitamin D in Hypertension.

Hypertension is the third leading cause of the global disease burden, and while populations live longer, adopt more sedentary lifestyles, and become less economically concerned, the prevalence of hypertension is expected to increase. Pathologically elevated blood pressure (BP) is the strongest risk factor for cardiovascular disease (CVD) and related disability, thus making it imperative to treat this disease. Effective standard pharmacological treatments, i.e., diuretics, angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blocker (ARBs), beta-adrenergic receptor blockers (BARBs), and calcium channel blockers (CCBs), are available. Vitamin D (vitD) is known best for its role in bone and mineral homeostasis. Studies with vitamin D receptor (VDR) knockout mice show an increased renin-angiotensin-aldosterone system (RAAS) activity and increased hypertension, suggesting a key role for vitD as a potential antihypertensive agent. Similar studies in humans displayed ambiguous and mixed results. No direct antihypertensive effect was shown, nor a significant impact on the human RAAS. Interestingly, human studies supplementing vitD with other antihypertensive agents reported more promising results. VitD is considered a safe supplement, proposing its great potential as antihypertensive supplement. The aim of this review is to examine the current knowledge about vitD and its role in the treatment of hypertension.

Comparison of the population of Polish patients participating in the TRANSITION study with the international population: a post hoc analysis.

INTRODUCTION: Heart failure (HF) patients discharged from a hospital are at a high risk of death and rehospitalization. Scarce data are available on the use of sacubitril / valsartan in this population in Poland. OBJECTIVE: The aim of this study was to compare the efficacy and tolerability of sacubitril / valsartan in the group of Polish patients who participated in the TRANSITION study with the patients recruited at other sites. PATIENTS AND METHODS: This is a post hoc secondary analysis of the TRANSITION study comparing sacubitril / valsartan initiation pre- vs postdischarge in 991 patients hospitalized for acute decompensated HF with reduced ejection fraction (HFrEF). The Polish subgroup consisted of 104 patients. RESULTS: Significant differences were identified in the characteristics of Polish vs non­Polish populations. At baseline, the Polish population showed higher proportion of men, higher body mass index, lower heart rate, N­terminal pro-B­type natriuretic peptide and high­sensitivity troponin T levels, and significantly lower New York Heart Association class. The Polish patients were better managed in terms of implanted electrotherapy devices, percutaneous coronary interventions, and drug therapy, and were more often hospitalized. The primary end point of achieving the target dose of sacubitril / valsartan at treatment week 10 was met by 45.6% of the Polish patients and 48.4% of the non­Polish population (P = 0.61). Approximately 90% of the Polish patients received and maintained any sacubitril / valsartan dose for 2 weeks over 10­week treatment vs 87.5% of the non­Polish patients (P = 0.36). The rate of permanent sacubitril / valsartan treatment discontinuation was low in both Polish (3.9%) and non­Polish populations (6.4%) (P = 0.33). CONCLUSIONS: Sacubitril / valsartan can be used safely in the early period after an episode of acute HF both in the Polish and non­Polish patients with HFrEF, and the likelihood to achieve the maximum dose is the same despite significant differences between the studied populations.

Effects of multifaceted optimization management for chronic heart failure: a multicentre, randomized controlled study.

AIMS: In recent years, we have developed the concept of 'clinical pathway based on integrated traditional Chinese and western medicine for the management of Chronic heart failure (CHF)'. The purpose of this study was to assess the implementation effects of multifaceted optimization management of chronic heart failure. METHODS: A total of nine physicians in optimization group from nine research sites received multifaceted intervention (a 1-day training session on how to implement the optimization programme, a written optimization programme for CHF management, supervision from daily quality coordinator, and 1-monthly monitoring and feedback of performance measure) with respect to the management of CHF, comparing to nine physicians in control group who did not receive the aforementioned multifaceted intervention and diagnosed and treated CHF patients with conventional programme (usual care). After that, a total of 256 patients with CHF were enrolled and randomly assigned to receive optimization programme [integration of usual care and traditional Chinese medicine (TCM) treatment] or conventional programme (usual care) for the treatment of CHF. The primary outcome was the change in New York Heart Association (NYHA) functional classification during 24 weeks of treatment. RESULTS: When compared with usual care, multifaceted optimization management resulted in superior improvements in NYHA functional classification at the 12-week visit (P = 0.023), the 16-week, 20-week, and 24-week visits (P < 0.001). It also demonstrated superior performance in comparison with the conventional programme with respect to readmission rate for major adverse cardiovascular events (MACEs), readmission rate for worsening heart failure, plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) level, left ventricular ejection fraction (LVEF), patient TCM syndrome scores, quality of life, and patients with heart failure with reduced ejection fraction (HFrEF) in optimization group more likely received beta-blockers and ACE inhibitors or ARBs than those in control group (P = 0.038 and P = 0.013, respectively). CONCLUSIONS: It is likely that the multifaceted optimization programme used in this study is feasible would benefit patients with CHF in NYHA functional classification, readmission for worsening heart failure, plasma NT-proBNP level, LVEF, patient TCM syndrome scores, and quality of life. Additionally, it would improve hospital personnel adherence to evidence-based performance measures for HFrEF.

Treatment of Hypertension: A Review.

Importance: Hypertension, defined as persistent systolic blood pressure (SBP) at least 130 mm Hg or diastolic BP (DBP) at least 80 mm Hg, affects approximately 116 million adults in the US and more than 1 billion adults worldwide. Hypertension is associated with increased risk of cardiovascular disease (CVD) events (coronary heart disease, heart failure, and stroke) and death. Observations: First-line therapy for hypertension is lifestyle modification, including weight loss, healthy dietary pattern that includes low sodium and high potassium intake, physical activity, and moderation or elimination of alcohol consumption. The BP-lowering effects of individual lifestyle components are partially additive and enhance the efficacy of pharmacologic therapy. The decision to initiate antihypertensive medication should be based on the level of BP and the presence of high atherosclerotic CVD risk. First-line drug therapy for hypertension consists of a thiazide or thiazidelike diuretic such as hydrochlorothiazide or chlorthalidone, an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker such as enalapril or candesartan, and a calcium channel blocker such as amlodipine and should be titrated according to office and home SBP/DBP levels to achieve in most people an SBP/DBP target (<130/80 mm Hg for adults <65 years and SBP <130 mm Hg in adults ≥65 years). Randomized clinical trials have established the efficacy of BP lowering to reduce the risk of CVD morbidity and mortality. An SBP reduction of 10 mm Hg decreases risk of CVD events by approximately 20% to 30%. Despite the benefits of BP control, only 44% of US adults with hypertension have their SBP/DBP controlled to less than 140/90 mm Hg. Conclusions and Relevance: Hypertension affects approximately 116 million adults in the US and more than 1 billion adults worldwide and is a leading cause of CVD morbidity and mortality. First-line therapy for hypertension is lifestyle modification, consisting of weight loss, dietary sodium reduction and potassium supplementation, healthy dietary pattern, physical activity, and limited alcohol consumption. When drug therapy is required, first-line therapies are thiazide or thiazidelike diuretics, angiotensin-converting enzyme inhibitor or angiotensin receptor blockers, and calcium channel blockers.

Novel antihypertensive agents for resistant hypertension: what does the future hold?

Finding complementary compelling novel therapeutic agents for better control of blood pressure in people with resistant hypertension is moving into unchartered territory. The latest therapeutic developments explore approaches in the clinical arena that were either not examined or could only be examined in animal models two decades ago. Four main mechanisms have now been explored and operationalized in drug development: (a) mineralocorticoid receptor blockade using a nonsteroidal structure with many fewer side effects, (b) an aminopeptidase A inhibitor that has central effects on vasopressin, (c) a combined endothelin A and B receptor blocker and (d) an aldosterone synthase inhibitor devoid of glucocorticoid activity. All these agents are either completing Phase II development and starting Phase III or are involved in the ongoing recruitment of Phase III trials. Additionally, novel agents use antisense inhibition to block angiotensinogen development in the liver. These agents are discussed only for completeness, as they are still in Phase II trial development. Last, another agent that was initially being developed as an antihypertensive and once the data were reviewed by the company clearly showed efficacy as a heart failure agent was sacubitril/valsartan, which was ultimately approved. However, there are some discussions about reinvigorating the quest for an indication for hypertension, although no such steps have been formally initiated.

Real-world use patterns of angiotensin receptor-neprilysin inhibitor (sacubitril/valsartan) among patients with heart failure within a large integrated health system.

BACKGROUND: Sacubitril/valsartan is a first-in-class angiotensin receptor-neprilysin inhibitor (ARNI) that is now preferred in guidelines over angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) for patients with heart failure with reduced ejection fraction (HFrEF). However, it has not been broadly adopted in clinical practice. OBJECTIVE: To characterize ARNI use within a large diverse real-world population and assess for any racial disparities. METHODS: We conducted a cross-sectional study within Kaiser Permanente Southern California. Adult patients with HFrEF who received ARNIs, ACEIs, or ARBs between January 1, 2014, and November 30, 2020, were identified. The prevalence of ARNI use among the cohort and patient characteristics by ARNIs vs ACEIs/ARBs use were described. Multivariable regression was performed to estimate odds ratios and 95% CIs of receiving ARNI by race and ethnicity. RESULTS: Among 12,250 patients with HFrEF receiving ACEIs, ARBs, or ARNIs, 556 (4.54%) patients received ARNIs. ARNI use among this cohort increased from 0.02% in 2015 to 7.48% in 2020. Patients receiving ARNIs were younger (aged 62 vs 69 years) and had a lower median ejection fraction (27% vs 32%) compared with patients receiving ACEIs/ARBs. They also had higher use of mineralocorticoid antagonists (24.1% vs 19.8%) and automatic implantable cardioverterdefibrillators (17.4% vs 13.3%). There were no significant differences in rate of ARNI use by race and ethnicity. CONCLUSIONS: Within a large diverse integrated health system in Southern California, the rate of ARNI use has risen over time. Patients given ARNIs were younger with fewer comorbidities, while having worse ejection fraction. Racial minorities were no less likely to receive ARNIs compared with White patients. DISCLOSURES: Dr Huang had stock ownership in Gilead and Pfizer. Dr Liang received support for article processing and medical writing.

Guideline-Directed Medical Therapy Before and After Primary Prevention Implantable Cardioverter Defibrillator Implantation in New Zealand (ANZACS-QI 66).

INTRODUCTION: Guidelines recommend angiotensin converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARB)/angiotensin receptor neprilysin inhibitors (ARNI); beta blockers; and mineralocorticoid receptor antagonists (MRA) in patients with symptomatic heart failure and reduced left ventricular ejection fraction before consideration of primary prevention implantable cardioverter defibrillator (ICD). This study aims to investigate dispensing rates of guideline-directed medical therapy (GDMT) before and after primary prevention ICD implantation in New Zealand. METHODS: All patients receiving a primary prevention ICD between 2009 and 2018 were identified using nationally collected data on all public hospital admissions in New Zealand. This was anonymously linked to national pharmaceutical data to obtain medication dispensing. Medications were categorised as low dose (<50% of target dose), 50-99% of target dose or target dose based on international guidelines. RESULTS: Of the 1,698 patients identified, ACEi/ARB/ARNI, beta blockers and MRA were dispensed in 80.2%, 83.6% and 45.4%, respectively, prior to ICD implant. However, ≥50% target doses of each medication class were dispensed in only 51.8%, 51.8% and 34.5%, respectively. Only 15.8% of patients were receiving ≥50% target doses of all three classes of medications. In the 1,666 patients who survived 1 year after ICD implant, the proportions of patients dispensed each class of medications remained largely unchanged. CONCLUSION: Dispensing of GDMT was suboptimal in patients before and after primary prevention ICD implantation in New Zealand, and only a minority received ≥50% target doses of all classes of medication. Interventions are needed to optimise use of these standard evidence-based medications to improve clinical outcomes and avoid unnecessary device implantation.

Actions of Novel Angiotensin Receptor Blocking Drugs, Bisartans, Relevant for COVID-19 Therapy: Biased Agonism at Angiotensin Receptors and the Beneficial Effects of Neprilysin in the Renin Angiotensin System.

Angiotensin receptor blockers (ARBs) used in the treatment of hypertension and potentially in SARS-CoV-2 infection exhibit inverse agonist effects at angiotensin AR1 receptors, suggesting the receptor may have evolved to accommodate naturally occurring angiotensin 'antipeptides'. Screening of the human genome has identified a peptide (EGVYVHPV) encoded by mRNA, complementary to that encoding ANG II itself, which is an inverse agonist. Thus, opposite strands of DNA encode peptides with opposite effects at AR1 receptors. Agonism and inverse agonism at AR1 receptors can be explained by a receptor 'switching' between an activated state invoking receptor dimerization/G protein coupling and an inverse agonist state mediated by an alternative/second messenger that is slow to reverse. Both receptor states appear to be driven by the formation of the ANG II charge-relay system involving TyrOH-His/imidazole-Carboxylate (analogous to serine proteases). In this system, tyrosinate species formed are essential for activating AT1 and AT2 receptors. ANGII is also known to bind to the zinc-coordinated metalloprotease angiotensin converting enzyme 2 (ACE2) used by the COVID-19 virus to enter cells. Here we report in silico results demonstrating the binding of a new class of anionic biphenyl-tetrazole sartans ('Bisartans') to the active site zinc atom of the endopeptidase Neprilysin (NEP) involved in regulating hypertension, by modulating humoral levels of beneficial vasoactive peptides in the RAS such as vasodilator angiotensin (1-7). In vivo and modeling evidence further suggest Bisartans can inhibit ANG II-induced pulmonary edema and may be useful in combatting SARS-CoV-2 infection by inhibiting ACE2-mediated viral entry to cells.

VA/DoD clinical practice guideline for the management of headache

The VA and DoD Evidence-Based Practice Work Group (EBPWG) was established and first chartered in 2004, with a mission to advise the VA/DoD Health Executive Committee "on the use of clinical and epidemiological evidence to improve the health of the population . . ." across the Veterans Health Administration (VHA) and Defense Health Agency (DHA), by facilitating the development of CPGs for the VA and DoD populations. Development and update of VA/DoD CPGs is funded by VA Evidence Based Practice, Office of Quality and Patient Safety. The system-wide goal of evidencebased CPGs is to improve patient health and wellbeing. In July 2020, the VA and DoD published a CPG for The Primary Care Management of Headache (2020 VA/DoD Headache CPG), which was based on evidence reviewed through March 2019. Since the release of that CPG, the evidence base on Headache has expanded. Consequently, the EBPWG initiated the update of the 2020 VA/DoD Headache CPG in 2023. This updated CPG's use of Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach reflects a more rigorous application of the methodology than previous iterations.(2) Therefore, the strength of some recommendations may have been modified due to the confidence in the quality of the supporting evidence (see Evidence Quality and Recommendation Strength). This CPG provides an evidence-based framework for evaluating and managing care for individuals living with Headache toward improving clinical outcomes. Successful implementation of this CPG will: • Assess the patient's condition and collaborate with the patient, family, and caregivers to determine optimal management of patient care; • Emphasize the use of patient-centered care and shared decision making; • Minimize preventable complications and morbidity; and • Optimize individual health outcomes and quality of life (QoL).

Pharmacotherapy of Alzheimer's disease: an overview of systematic reviews.

BACKGROUND: Alzheimer's disease (AD) is a neurodegenerative disease and the most common cause of dementia. In this umbrella systematic review (SR), we summarized the efficacy of different pharmacological interventions in improving cognitive function in patients with AD. METHODS: A systematic search was performed through the PubMed, Scopus, Embase, and Cochrane databases for SRs of studies assessing the efficacy of pharmacological interventions versus placebo in improving cognitive function in AD or mild cognitive impairment due to AD. The risk of bias (RoB) was assessed using the Risk of Bias in SRs (ROBIS) tool. RESULTS: Out of 1748 articles found through the database survey, 33 SR articles were included. These studies assessed effects of immunotherapy, cholinesterase inhibitors (ChEIs), memantine, statins, lithium, nonsteroidal anti-inflammatory drugs (NSAIDs), antidiabetic agents, Cerebrolysin, RAS-targeting antihypertensive drugs (ARBs and ACEIs), psychostimulants, glycogen synthase kinase 3 (GSK-3) inhibitors, melatonin, and herbal medications on cognitive function in AD patients. There was no notable overall RoB in 18 studies (54.5%), the RoB in 14 studies (42.4%) was high, and in one study (3.0%) it was unclear. CONCLUSIONS: The use of ChEIs, including rivastigmine, galantamine, and donepezil, as well as memantine has demonstrated a positive impact on improving cognitive outcomes of AD patients, but no considerable effects were found for immunotherapies. Melatonin, statins, antihypertensive drugs, antidiabetic agents, Cerebrolysin, psychostimulants, and some herbal drugs such as Danggui-Shaoyao-San and Ginkgo biloba seem to be effective in improving cognitive function of AD patients, but the evidence in this regard is limited.

Comparative efficacy of seven Chinese patent medicines for early diabetic kidney disease: A Bayesian network meta-analysis.

BACKGROUND: Bailing Capsule (BLC), Jinshuibao (JSB), Huangkui Capsule (HKC), Uremic Clearance Granule (UCG), Tripterygium glycosides (TG), Compound Xueshuantong Capsule (CXC), and Shenyan Kangfu Tablet (SYKFT) as classic Chinese patent medicines (CPMs), have been widely used and shown beneficial effects on the treatment of early diabetic kidney disease (DKD). However, the comparative efficacy of seven CPMs in the treatment of early DKD remains unknown. OBJECTIVE: To evaluate and compare the efficacy of seven CPMs (BLC, JSB, HKC, UCG, TG, CXC, SYKFT) combined with angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) on early DKD by a Bayesian network meta-analysis (NMA) of randomized controlled trials (RCTs). METHODS: A comprehensive and systematic literature search was performed in PubMed, Embase, Cochrane Library, Web of Science, Clinical Trials.gov, China Biology Medicine, Chinese National Knowledge Infrastructure, Chinese Scientific Journal, and Wanfang databases from inception to March 14, 2021, for full-text RCTs that evaluated the efficacy of seven CPMs combined with ACEI/ARB on patients with early DKD. Two reviewers independently screened studies for eligibility, extracted data, and assessed the risk of bias. Agreement between reviewers was measured using kappa statistics. Mean difference (MD) and odds ratio (OR) were calculated to evaluate continuous variables and dichotomous, respectively. The random effect modeling NMA was performed and the ranking probability of interventions in various outcomes was also conducted based on the surface under the cumulative ranking curve (SUCRA). Begg's and Egger's tests were used to evaluate publication bias. The certainty of the evidence for outcomes was evaluated according to the GRADE system. RESULTS: A total of 62 RCTs with 5362 patients with early DKD were identified. The value of Kappa calculated for the various parameters extracted by the two investigators was 0.821 (P < 0.001). Among these CPMs, UCG + ACEI/ARB showed the best effectiveness for urinary albumin excretion rate (UAER) (MD 32.25, 95% CrI 19.11-45.67, low certainty) with SUCRA 92%. JSB + ACEI/ARB showed the highest effectiveness for 24-h urinary total protein (24-h UTP) (MD 76.92, 95% CrI 53.54-100.58, low certainty) with SUCRA 97%. CXC + ACEI/ARB showed the highest effectiveness for serum creatinine (SCr) (MD 26.02, 95% CrI 6.10-45.95, low certainty) with SUCRA 96%. HKC + ACEI/ARB showed the highest effectiveness for blood urea nitrogen (BUN) (MD 1.46, 95% CrI 0.42-2.54, very low certainty) with SUCRA 86%. BLC + ACEI/ARB showed significant differences in triglyceride (TRIG) (MD - 1.17, 95% CrI - 1.93 to - 0.43, low certainty) with SUCRA 90%, total cholesterol (TC) (MD - 1.17, 95% CrI - 1.97 to - 0.39, very low certainty) with SUCRA 90%, and C-reaction protein (CRP) (MD - 0.90, 95% CrI - 1.51 to - 0.32, very low certainty) with SUCRA 76%. CONCLUSIONS: CPMs + ACEI/ARB might be positive efficacious interventions from which patients with DKD will derive benefit. UCG + ACEI/ARB, JSB + ACEI/ARB, CXC + ACEI/ARB, and HKC + ACEI/ARB might be potentially the preferred intervention for reducing UAER, 24-h UTP, SCr, and BUN levels, respectively. BLC + ACEI/ARB has a better impact on lowing TRIG, TC, and CRP levels in patients with early DKD. However, more high-quality, large-scale, multi-center RCTs and stronger head-to-head trials are required to confirm these findings.

Sacubitril/Valsartan: A New Dawn has Begun! A Revisited Review.

Heart Failure (HF) is among the major causes of global morbidity as well as mortality. Increased prevalence, frequent and prolonged hospitalization, rehospitalization, long-term consumption of healthcare resources, absenteeism, and death upsurge the economic burden linked to HF. For decades, Angiotensin-Converting Enzyme Inhibitors (ACEIs), Angiotensin II Receptor Blockers (ARBs), Beta-Blockers (BBs), and mineralocorticoid receptor antagonists (MRA), have remained the mainstay of the standard of care for HF management. Despite their proven efficacy and cost-effectiveness, HF remains a global pandemic and is still increasing in prevalence. Sacubitril/ Valsartan (SAC/VAL) is an Angiotensin Receptor/Neprilysin Inhibitor (ARNI) that proved out to be a game-changer drug in HF treatment. Recent data indicated that SAC/VAL is more efficient and can improve the overall quality of life of HF patients with reduced ejection fraction (HFrEF) with fewer side effects. It is now incorporated in the guidelines as an alternative to ACEIs or ARBs to lower morbidity in addition to mortality in HFrEF patients. This review article will discuss the current guidelines-approved indications and highlight the potential emerging indications, in addition to the currently ongoing clinical trials that will expand the use of SAC/VAL.

Dyskalemia risk associated with fixed-dose anti-hypertensive medication combinations.

A model-based meta-analysis quantified comparative dyskalemia risk (hyper- or hypo-kalemia) in hypertensive patients treated with angiotensin receptor blockers (ARBs), a calcium channel blocker (CCB) and/or a thiazide diuretic (hydrochlorothiazide; HCTZ) as monotherapy or as fixed-dose combinations. Among 15 randomized controlled trials in a US Food and Drug Administration regulatory review database, dyskalemia events were reported by five trials (24 treatment arms, 11,030 subjects, 8-week median follow up time). The five trials evaluated monotherapy (ARB or HCTZ) alongside dual (ARB + HCTZ, ARB + CCB, or HCTZ + CCB) or triple fixed-dose combinations (ARB + CCB + HCTZ). Hypo- and hyper-kalemia rates were analyzed jointly to account for correlation. Significant drug class, drug, or dose effects were included in the final model. Effect on various drug- and dose combinations on dyskalemia risk were simulated and compared with model-estimated placebo arm dyskalemia risk. After a typical follow-up of 8 weeks, fixed-dose combinations of ARB with a high dose (25 mg) of HCTZ were associated with a higher hypokalemia risk difference (RD) from placebo (e.g.,Valsartan + HCTZ: 2.52%[95%CIs:1.17, 4.38%]). However, when ARB was combined with a lower, 12.5 mg dose of HCTZ, hypokalemia RD from placebo was not significant (Valsartan + HCTZ: -0.03%[-0.80, 0.71%]). ARB monotherapy raised hyperkalemia RD from placebo (1.3%[0.3, 3.6%]). Hyperkalemia risk was not appreciably higher than placebo for any FDC that combined ARB with HCTZ (Valsartan + HCTZ: 0.06%[-1.48, 1.64%]). In uncomplicated hypertensive patients, ARB + 12.5 mg HCTZ fixed-dose combinations are safer with respect to dyskalemia than either ARB or HCTZ monotherapy for initial antihypertensive treatment.

Traditional Chinese medicine enhances myocardial metabolism during heart failure.

The prognosis of various cardiovascular diseases eventually leads to heart failure (HF). An energy metabolism disorder of cardiomyocytes is important in explaining the molecular basis of HF; this will aid global research regarding treatment options for HF from the perspective of myocardial metabolism. There are many drugs to improve myocardial metabolism for the treatment of HF, including angiotensin receptor blocker-neprilysin inhibitor (ARNi) and sodium glucose cotransporter 2 (SGLT-2) inhibitors. Although Western medicine has made considerable progress in HF therapy, the morbidity and mortality of the disease remain high. Therefore, HF has attracted attention from researchers worldwide. In recent years, the application of traditional Chinese medicine (TCM) in HF treatment has been gradually accepted, and many studies have investigated the mechanism whereby TCM improves myocardial metabolism; the TCMs studied include Danshen yin, Fufang Danshen dripping pill, and Shenmai injection. This enables the clinical application of TCM in the treatment of HF by improving myocardial metabolism. We systematically reviewed the efficacy of TCM for improving myocardial metabolism during HF as well as the pharmacological effects of active TCM ingredients on the cardiovascular system and the potential mechanisms underlying their ability to improve myocardial metabolism. The results indicate that TCM may serve as a complementary and alternative approach for the prevention of HF. However, further rigorously designed randomized controlled trials are warranted to assess the effect of TCM on long-term hard endpoints in patients with cardiovascular disease.

Cardiovascular and kidney outcomes of spironolactone or eplerenone in combination with ACEI/ARBs in patients with diabetic kidney disease.

BACKGROUND: Mineralocorticoid receptor antagonist (MRA) when combined with either angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) may provide additional benefits of cardiovascular and kidney disease risk reduction in patients with diabetic kidney disease (DKD) and hypertension. We evaluated the effectiveness of combination therapy (MRAs, either spironolactone or eplerenone, plus ACEI/ARB) compared with monotherapy (ACEI/ARB only) in patients with DKD and hypertension. METHODS: Retrospective cohort study was performed in patients (age ≥ 18 years) with hypertension, diabetes, and albuminuria between 2008 and 2018 within an integrated health system. MRA with ACEI/ARB compared to ACEI/ARB alone was evaluated on composite of cardiovascular events, progression to end-stage kidney disease, or all-cause mortality. Hyperkalemia was compared as a safety outcome. RESULTS: We identified 1282 patients who received MRAs with ACEI/ARBs and 5484 patients who received ACEI/ARBs alone. Median exposure time for combination therapy was 126 days. The rates per 100 person-years of cardiovascular, kidney, or all-cause mortality outcomes were 12.2 and 9.2 for combination therapy and monotherapy, respectively (hazard ratios = 1.24, 95% Confidence Interval (CI):0.94, 1.63). Patients receiving combination therapy had greater reduction in urine albumin-to-creatinine ratio compared with monotherapy (Mean reduction: 823 and 585 mg/g; p < 0.001, respectively). Hyperkalemia was more frequent in combination therapy versus monotherapy (22.3 vs. 10.9 per 100 person-years for combination and monotherapy, respectively; hazard ratios = 1.78, 95%CI: 1.42, 2.24). CONCLUSIONS: Among patients with DKD and hypertension, the short-term use of MRAs, either spironolactone or eplerenone, in combination with ACEI/ARBs, was not associated with lower risk of cardiovascular or kidney outcomes compared with ACEI/ARB monotherapy. The risk of hyperkalemia and the short duration of combination therapy may suggest a real-world clinical challenge for MRA with ACEI/ARB combination therapy.
