Curr Cardiol Rev 2024; 20:13-29. [PMID: 38347774 DOI: 10.2174/011573403x289572240206112303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 01/15/2024] [Accepted: 01/22/2024] [Indexed: 04/21/2024] Open
Abstract
BACKGROUND Chronic heart failure (HF) is frequently associated with various comorbidities. These comorbid conditions, such as anemia, diabetes mellitus, renal insufficiency, and sleep apnea, can significantly impact the prognosis of patients with HF. OBJECTIVE This review aims to synthesize current evidence on the prevalence, impact, and management of comorbidities in patients with chronic HF. METHODS A comprehensive review was conducted, with a rigorous selection process. Out of an initial pool of 59,030 articles identified across various research modalities, 134 articles were chosen for inclusion. The selection spanned various research methods, from randomized controlled trials to observational studies. RESULTS Comorbidities are highly prevalent in patients with HF and contribute to increased hospitalization rates and mortality. Despite advances in therapies for HF with reduced ejection fraction, options for treating HF with preserved ejection fraction remain sparse. Existing treatment protocols often lack standardization, reflecting a limited understanding of the intricate relationships between HF and associated comorbidities. CONCLUSION There is a pressing need for a multidisciplinary, tailored approach to manage HF and its intricate comorbidities. This review underscores the importance of ongoing research efforts to devise targeted treatment strategies for HF patients with various comorbid conditions.

Abstract
Cardiovascular diseases have become a major clinical burden globally. Heart failure is one of the diseases that commonly emanates from progressive uncontrolled hypertension. This gives rise to the need for a new treatment for the disease. Sacubitril/valsartan is a new drug combination that has been approved for patients with heart failure. This review aims to detail the mechanism of action for sacubitril/valsartan in cardiac remodeling, a cellular and molecular process that occurs during the development of heart failure. Accumulating evidence has unveiled the cardioprotective effects of sacubitril/valsartan on cellular and molecular modulation in cardiac remodeling, with recent large-scale randomized clinical trials confirming its supremacy over other traditional heart failure treatments. However, its molecular mechanism of action in cardiac remodeling remains obscure. Therefore, comprehending the molecular mechanism of action of sacubitril/valsartan could help future research to study the drug's potential therapy to reduce the severity of heart failure.

Abstract
Congenital heart disease is one of the most common causes of death derived from malformations. Historically, its treatment has depended on timely diagnosis and early pharmacological and surgical interventions. Survival rates for patients with this disease have increased, primarily due to advancements in therapeutic choices, but mortality remains high. Since this disease is a time-sensitive pathology, pharmacological interventions are needed to improve clinical outcomes. Therefore, we analyzed the applications, dosage, and side effects of drugs currently used for treating congenital heart disease. Angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta-blockers, and potassium-sparing diuretics have shown a mortality benefit in most patients. Other therapies, such as endothelin receptor antagonists, phosphodiesterase-5 inhibitors, prostaglandins, and soluble guanylyl cyclase stimulators, have benefited patients with pulmonary artery hypertension. Likewise, the adjunctive symptomatic treatment of these patients has further improved the outcomes, since antiarrhythmics, digoxin, and non-steroidal anti-inflammatory drugs have shown their benefits in these cases. Conclusively, these drugs also carry the risk of troublesome adverse effects, such as electrolyte imbalances and hemodynamic compromise. However, their benefits for survival, symptom improvement, and stabilization outweigh the possible complications from their use. Thus, cases must be assessed individually to accurately identify interventions that would be most beneficial for patients.

An Overview of Clinically Imperative and Pharmacodynamically Significant Drug Interactions of Renin-Angiotensin-Aldosterone System (RAAS) Blockers. Curr Cardiol Rev 2022; 18:e110522204611. [PMID: 35546745 PMCID: PMC9893153 DOI: 10.2174/1573403x18666220511152330] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 02/26/2022] [Accepted: 03/28/2022] [Indexed: 11/22/2022] Open
Abstract
INTRODUCTION Hypertension is a leading cause of cardiovascular disease and chronic kidney disease, resulting in premature death and disability. The Renin-Angiotensin-Aldosterone System (RAAS) blockers, including Angiotensin-Converting Enzyme (ACE) inhibitors or Angiotensin Receptor Blockers (ARBs), are used as first-line antihypertensive therapy to treat hypertensive patients with comorbidities, including diabetes, ischemic heart disease, heart failure, and chronic kidney disease. The use of RAS blockers is associated with the risks, such as hyperkalemia, angioedema, etc. The drugs potentiating them interact pharmacodynamically, resulting in adverse consequences. This review article focuses on the clinically important drug interactions of RAAS blockers. MATERIALS AND METHODS The electronic databases, such as Medline/PubMed Central/PubMed, Google Scholar, ScienceDirect, Cochrane Library, Directory of Open Access Journals (DOAJ), Embase, and reference lists were searched to identify relevant articles. RESULTS The risk of hyperkalemia may be enhanced potentially in patients receiving a RAS blocker and potassium-sparing diuretics, potassium supplements, trimethoprim, adrenergic betablockers, antifungal agents, calcineurin inhibitors, pentamidine, heparins or an NSAID, concomitantly. The patients taking ACE inhibitors and mTOR inhibitors, DPP4 inhibitors, alteplase, or sacubitril/valsartan concurrently may be at increased risk of developing angioedema. CONCLUSION Clinicians, pharmacists, and other healthcare practitioners should be accountable for medication safety. To avoid adverse implications, prescribers and pharmacists must be aware of the drugs that interact with RAAS blockers.

Abstract
Heart failure (HF) is a leading cause of disease and death from cardiovascular diseases, with cardiovascular diseases accounting for the highest cases of deaths worldwide. The reality is that the quality-of-life survival for those suffering HF remains poor with 45-60% reported deaths within five years. Furthermore, cardiovascular disease is the foremost cause of mortality and disability in people with type 2 diabetes mellitus (T2DM), with T2DM patients having a two-fold greater risk of developing heart failure. The number of T2DM affected persons only continues to surge as there are more than 400 million adults affected by diabetes and an estimated 64.3 million affected by heart failure globally (1). In order to cater to the demands of modern society, the medical field has continuously improved upon the standards for clinical management and its therapeutic approaches. For this purpose, in this review, we aim to provide an overview of the current updates regarding heart failure, to include both heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF) and their respective treatments, while also diving further into heart failure and its correlation with diabetes and diabetic cardiomyopathy and their respective therapeutic approaches.

Synchronized determination of the novel heart failure combination therapy containing sacubitril calcium and valsartan by a validated spectrofluorimetric method. SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2021; 253:119613.

Abstract
A sensitive and accurate spectrofluorimetric method was proposed for the determination of Sacubitril calcium and Valsartan simultaneously in binary mixture. The method was established on measuring the native fluorescence of Sacubitril calcium and Valsartan upon excitation at 240 nm in acetonitrile. The emission of Sacubitril calcium was measured at 615 nm. For the determination Valsartan a first derivative ratio method was employed to eliminate any spectral interference. The ratio emission spectra were achieved by dividing the emission spectra of various concentrations of Valsartan by the emission spectrum of Sacubitril calcium (100 ng/ml) then the first derivative of the obtained ratio emission spectra was recorded using the proper smoothing factor. The amplitude at 354.9 nm on the first derivative ratio emission spectrum was used to calculate the concentrations of Valsartan in presence of Sacubitril calcium. The method was linear over the concentration range 100-1000 ng/ml for both Sacubitril calcium and Valsartan. The mean accuracy values were found to be 99.32 ± 0.62 and 99.30 ± 0.70 for Sacubitril calcium and Valsartan, respectively. Statistical comparison between results obtained by the proposed method and a reported method for this drugs showed no significant difference. This developed method was used for the quantitative determination of Sacubitril calcium and Valsartan in both pure and pharmaceutical dosage form.

Development of a multistep reaction cascade for the synthesis of a sacubitril precursor in continuous flow. J Flow Chem 2019.

Abstract
AbstractThe active pharmaceutical ingredient sacubitril acts as a neprilysin inhibitor in the body and is administered to patients suffering from high blood pressure and chronic heart failure. In this paper, we report the development of a three-step setup for the synthesis of an advanced sacubitril precursor in continuous flow. The key transformation of our cascade is a Suzuki-Miyaura coupling facilitated by a heterogeneous palladium catalyst. Its implementation in a packed-bed reactor and the application of continuous flow methodologies allow intensification of the cross-coupling reaction compared to batch processing. The subsequent steps for the synthesis of the target molecule involve Boc-deprotection as well as N-succinylation, which have been optimized using the statistical “Design of Experiments” (DoE) approach. In this way, the individual as well as interactive effects of selected parameters on the output of the reactions could be investigated very efficiently. The consecutive performance of the three reaction steps using an integrated setup enabled the synthesis of a late-stage sacubitril precursor in continuous flow with 81% overall yield.

Application and impact of run-in studies. J Gen Intern Med 2018; 33:759-763. [PMID: 29450684 PMCID: PMC5910356 DOI: 10.1007/s11606-018-4344-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/26/2017] [Revised: 01/03/2018] [Accepted: 01/19/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND A run-in phase is often employed prior to randomization in a clinical trial to exclude non-adherent patients, placebo responders, active drug non-responders, or patients who do not tolerate the active drug. This may impact the generalizability of trial results. OBJECTIVE To determine if clinical outcomes differed between randomized controlled trials with run-in phases compared with randomized controlled trials of the same medication without run-in phases. DESIGN, PARTICIPANTS From 2006 to 2014, the Food and Drug Administration approved 258 new medications. Sitaglitpin, saxagliptin, linagliptin, and alogliptin were among the only drugs with a common mechanism of action that each had multiple clinical trials, some of which had run-in phases and some of which did not. We identified all published randomized controlled trials for these four medications from MEDLINE and EMBASE as well as prior systematic reviews. MAIN MEASURES We extracted key measures of medication efficacy (reduction in hemoglobin A1C) and safety (serious adverse events) from qualifying trials. Study results were pooled for each medication using random effects meta-analysis. KEY RESULTS We identified 106 qualifying trials for DPP4 inhibitors, of which 88 had run-in phases and 18 did not. The average run-in phase duration was 4.0 weeks (range 1-21), and 73% of run-in phases administered placebo rather than active drug. The reduction in hemoglobin A1C compared to baseline was similar for trials with and without run-in phases (0.70%, 95% confidence interval [CI] 0.65-0.75 vs 0.76%, 95% CI 0.69-0.84, p = 0.27). The proportion of patients with serious adverse events was also similar for trials with and without run-in phases (4%, 95% CI: 3-5% vs 3%, 95% CI: 1-4%, p = 0.35). CONCLUSION Trials with run-in phases provided similar estimates for medication efficacy and safety compared to trials without run-in phases. Because run-in phases are costly and time-consuming, these results call their utility into question for clinical trials of short duration.

Abstract
Within the “compartmentalised smart factory” approach of the ONE-FLOW project the implementation of different catalysts in “compartments” provided by Pickering emulsions and their application in continuous flow is targeted. We present here the development of heterogeneous Pd catalysts that are ready to be used in combination with biocatalysts for catalytic cascade synthesis of active pharmaceutical ingredients (APIs). In particular, we focus on the application of the catalytic systems for Suzuki–Miyaura cross-coupling reactions, which is the key step in the synthesis of the targeted APIs valsartan and sacubitril. An immobilised enzyme will accomplish the final product formation via hydrolysis. In order to create a large interfacial area for the catalytic reactions and to keep the reagents separated until required, the catalyst particles are used to stabilise Pickering emulsions of oil and water. A set of Ce–Sn–Pd oxides with the molecular formula Ce0.99−xSnxPd0.01O2−δ (x = 0–0.99) has been prepared utilising a simple single-step solution combustion method. The high applicability of the catalysts for different functional groups and their minimal leaching behaviour is demonstrated with various Suzuki–Miyaura cross-coupling reactions in batch as well as in continuous flow employing the so-called “plug & play reactor”. Finally, we demonstrate the use of these particles as the sole emulsifier of oil–water emulsions for a range of oils.

Abstract
Aims Sacubitril/valsartan is indicated for the treatment of heart failure and reduced ejection fraction (HFrEF). Furosemide, a loop diuretic commonly used for the treatment of HFrEF, may be coadministered with sacubitril/valsartan in clinical practice. The effect of sacubitril/valsartan on the pharmacokinetics and pharmacodynamics of furosemide was evaluated in this open label, two‐period, single‐sequence study in healthy subjects. Methods All subjects (n = 28) received 40 mg oral single‐dose furosemide during period 1, followed by a washout of 2 days. In period 2, sacubitril/valsartan 200 mg (97/103 mg) was administered twice daily for 5 days and a single dose of 40 mg furosemide was coadministered on day 6. Serial plasma and urine samples were collected to determine the pharmacokinetics of furosemide and sacubitril/valsartan and the pharmacodynamics of furosemide. The point estimates and the associated 90% confidence intervals for pharmacokinetic parameters were evaluated. Results Coadministration of furosemide with sacubitril/valsartan decreased the maximum observed plasma concentration (Cmax) [estimated geometric mean ratio (90% confidence interval): 0.50 (0.44, 0.56)], area under the plasma concentration–time curve (AUC) from time 0 to infinity [0.72 (0.67, 0.77)] and 24‐h urinary excretion of furosemide [0.74 (0.69, 0.79)]. When coadministered with sacubitril/valsartan, 0–4‐h, 4–8‐h and 0–24‐h diuresis in response to furosemide was reduced by ~7%, 21% and 0.2%, respectively, while natriuresis was reduced by ~ 28.5%, 7% and 15%, respectively. Post hoc analysis of the pivotal phase III Prospective comparison of ARNI with ACEI to Determine Impact on Global Mortality and morbidity in Heart Failure trial (PARADIGM‐HF) indicated that the median furosemide dose was similar at baseline and at the end of the study in the sacubitril/valsartan group. Conclusions Sacubitril/valsartan reduced plasma Cmax and AUC and 24‐h urinary excretion of furosemide, while not significantly affecting its pharmacodynamic effects in healthy subjects.

Abstract
Hypertension (HTN) is a well-known health problem associated with considerable morbidity and mortality and it is an important risk factor for the development of heart failure (HF). These findings support the need for optimizing the antihypertensive strategies to prevent the progression to HF. Interestingly, the progression from HTN to HF, among other things, may be a consequence of inappropriate over-activation of the renin-angiotensin-aldosterone system (RAAS), sympathetic nervous system (SNS), and the natriuretic peptide system (NPS). In the present review, we will discuss the pathophysiological aspects of the progression from HTN to HF with reduced ejection fraction (HFrEF) and we will focus on the evolution of different pharmacological therapies which are reported to be effective in reducing BP and improving HF outcomes, paying particular attention to the recent trials that have demonstrated the efficacy of the combined therapy of RAAS blockade and Neprilysin (NEP) inhibitor in lowering BP and mediating several beneficial actions within cardiovascular tissues, such as avoiding the worsening of HF.
