AI Article Synopsis
- Vasoactive and inotropic drugs can quickly relieve symptoms and improve blood flow in patients.
- These drugs may lead to higher mortality rates if used over the long term.
- Their application should follow specific clinical guidelines to ensure safe and effective treatment.
Article Abstract
Vasoactive and inotropic drugs provide effective symptomatic and hemodynamic relief in the short term but can increase mortality in the long-term. Consequently, their use should be restricted to the indications described in clinical practice guidelines. The present article reviews the main drugs and the available evidence on their use.

Introduction: Adrenergic activation of protein kinase A (PKA) in cardiac muscle targets the sarcolemma, sarcoplasmic reticulum, and contractile apparatus to increase contractile force and heart rate. In the thin filaments of the contractile apparatus, cardiac troponin I (cTnI) Ser22 and Ser23 in the cardiac-specific N-terminal peptide (NcTnI: residues 1 to 32) are the targets for PKA phosphorylation. Phosphorylation causes a 2-3 fold decrease of affinity of cTn for Ca associated with a higher rate of Ca dissociation from cTnC leading to a faster relaxation rate of the cardiac muscle (lusitropy).

However, the effects of blood pressure (BP) and changes in BP on bleeding events in patients undergoing percutaneous coronary intervention (PCI) remain poorly understood. This study is aimed to investigate the relationship between systolic BP (SBP) changes during hospitalisation and bleeding events in patients undergoing PCI.

Introduction: Myocardial protection with cardioplegia is a crucial approach to mitigate myocardial damage during coronary bypass grafting surgery (CABG) with cardiopulmonary bypass (CPB). The major component of the del Nido cardioplegia solution, Plasma-Lyte A, is difficult to obtain in Iran due to high cost. The objective of the current study was to study if the lactated Ringer's solution as the base for del Nido solution (LR DN) usage is a viable option as a substitute for Plasma-Lyte A in adult patients presenting for CABG surgery.

This study aims to investigate the effect of Zhishi Xiebai Guizhi Decoction on the phenotypic transformation of pulmonary artery smooth muscle cells(PASMCs) in rats with hypoxic pulmonary hypertension(HPH). Healthy SPF SD rats were randomly assigned to five groups: control group, hypoxia model group, hypoxia + low-dose Zhishi Xiebai Guizhi Decoction group(440 mg·kg~(-1)·d~(-1)), hypoxia + high-dose Zhishi Xiebai Guizhi Decoction group(880 mg·kg~(-1)·d~(-1)), and hypoxia + sildenafil group(30 mg·kg~(-1)·d~(-1)), with right rats in each group. Rats in the hypoxia model and hypoxia + drug groups were exposed to a hypobaric oxygen chamber with a simulated altitude of 5 000 m to induce the PH model.

Article Synopsis
- Esophageal achalasia is a condition that affects the lower esophageal sphincter (LES), leading to symptoms like difficulty swallowing, chest pain, and weight loss, with traditional treatments providing limited relief.
- This study investigates the effectiveness of Traditional Chinese Medicine, specifically Coptis chinensis and its active component berberine, in promoting LES relaxation as a potential alternative treatment.
- Results indicate that both C. chinensis extract and berberine significantly relax the LES by activating potassium channels, suggesting further research is warranted for their therapeutic use in esophageal disorders like achalasia.
