Efficacy and safety of vericiguat in heart failure: a meta-analysis

OBJECTIVE

This study aimed to investigate the safety and efficacy of vericiguat in patients with heart failure (HF).

METHODS

We conducted a comprehensive literature review of the PubMed, Embase, and Cochrane Library databases up to 14 December 2022 for studies comparing vericiguat with placebo in patients with HF. Clinical data were extracted and cardiovascular deaths, adverse effects, and HF-related hospitalization were analyzed using Review Manager software (version 5.3), after quality assessment of the enrolled studies.

RESULTS

Four studies (6705 patients) were included in this meta-analysis. There were no significant differences in the basic characteristics of the included studies. There was no significant difference in adverse effects between the vericiguat group and placebo group, and no significant differences between the groups in terms of cardiovascular death and HF hospitalization.

CONCLUSION

This meta-analysis indicated that vericiguat was not an effective drug for HF; however, more clinical trials are required to verify its efficacy.

Molecular mechanisms of sacubitril/valsartan in cardiac remodeling

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.

Effectiveness of sacubitril-valsartan in patients with cancer therapy-related cardiac dysfunction: a systematic review of clinical and preclinical studies

INTRODUCTION

Cancer therapy-related cardiac dysfunction (CTRCD) is a critical problem with an impact on both oncological and cardiovascular prognosis, especially when it prevents patients from receiving cancer treatment. However, there are very limited data on the efficacy of sacubitril/valsartan in the prevention and treatment of cardiotoxicity. This systematic review aimed to evaluate the potential benefit of sacubitril/valsartan in patients with CTRCD.

EVIDENCE ACQUISITION

The databases included MEDLINE, Embase, LILACS, Scopus and Cochrane Central up to January 20, 2022. All pre-clinical and clinical studies including observational studies (cohorts, case-control, cross-sectional and case reports) that used sacubitril/valsartan for prevention or treatment of CTRCD. The primary effectiveness endpoints was CTRCD, defined as a clinically significant change in left ventricular ejection fraction (LVEF) at the end of the follow-up.

EVIDENCE SYNTHESIS

And after applying the eligibility criteria, 12 articles (9 in humans and 3 preclinical studies) were included in this systematic review. The 3 preclinical studies demonstrated beneficial effects in preventing, attenuating and/or delaying the onset of myocardial damage at the cellular level, ventricular dysfunction and remodeling. Regardind human studies, most of them were composed of case reports. The largest study consisted of a retrospective multicentric cohort with 64 patients.

CONCLUSIONS

All clinical studies have demonstrated that used Sac/Val in human showed a significant increase in LVEF, and when reported, a reduction in left ventricular volume and NT-proBNP (or BNP). Randomized clinical trials are needed to confirm this hypothesis.
