We recently used an endoscopy-based resection method to explore the consequences of cardiac injury in adult , obtaining the result that the adult heart is unable to regenerate. At 11 months post-amputation, cellular and biological marks of scarring persisted. We thus concluded that, contrary to urodeles and teleosts, adult anurans share a cardiac injury outcome similar to adult mammals. However, in their work published in this journal on the 13 December 2017, Liao et al. showed that the adult heart is capable of efficient, almost scar free regeneration, a result at odds with our previous observation. These findings contrast with and challenge the outcome of adult heart repair following injury in species. Here we discuss the question of the intrinsic cardiac regenerative properties of an adult heart in anuran amphibians.

Pharmacologic Management of Heart Failure with Preserved Ejection Fraction (HFpEF) in Older Adults.

There are several pharmacologic agents that have been touted as guideline-directed medical therapy for heart failure with preserved ejection fraction (HFpEF). However, it is important to recognize that older adults with HFpEF also contend with an increased risk for adverse effects from medications due to age-related changes in pharmacokinetics and pharmacodynamics of medications, as well as the concurrence of geriatric conditions such as polypharmacy and frailty. With this review, we discuss the underlying evidence for the benefits of various treatments in HFpEF and incorporate key considerations for older adults, a subpopulation that may be at higher risk for adverse drug events.

Background: Most older patients with atrial fibrillation (AF) have comorbidities. However, it is unclear whether specific comorbidity patterns are associated with adverse outcomes. We identified comorbidity patterns and their association with mortality in multimorbid older AF patients with different multidimensional frailty.

Background: The lacking proper regulation of International Normalized Ratio (INR) as the main problem in patients with mechanical valve replacement surgery poses the risk of thrombosis and embolism on the one hand and the risk of bleeding on the other. For this reason, the correct monitoring of INR via the Time in Therapeutic Range (TTR) is needed. The present study aimed to explore the blood coagulation monitoring of patients with mechanical heart valve in Imam Ali Hospital of Kermanshah in 2021.

Objective: This study aims to investigate the monthly variation patterns of bioelectrical impedance (BEI) along 24 meridian pathways in healthy individuals.
Methods: A cohort of 684 healthy middle-aged participants from North China was enrolled between July 1, 2017, and September 5, 2020. BEI measurements were consistently recorded along the 24 meridian pathways over the study period.
