AI Article Synopsis
- The study aims to evaluate the cost-effectiveness of enhanced external counterpulsation (EECP) for treating chronic stable angina in the UK, comparing it to no treatment in addition to usual care.
- The research involved a systematic review of existing studies, expert opinions where data was lacking, and a decision analytic model to analyze costs and health outcomes over a lifetime.
- Results showed that EECP had an incremental cost-effectiveness ratio of £18,643 per additional quality-adjusted life-year (QALY), with varied probabilities of being deemed cost-effective depending on the threshold; further long-term studies on quality of life are essential to solidify findings.
Article Abstract
Objectives: The objective of this study is to assess the cost-effectiveness of enhanced external counterpulsation (EECP) compared with no treatment as additional therapy to usual care for the treatment of chronic stable angina from the perspective of the UK National Health Service.
Methods: The study design was a systematic review of published evidence, use of expert clinical opinion, and decision analytic cost-effectiveness model. The systematic review was conducted and statistical methods used to synthesize the effectiveness evidence from randomized control trials. Formal methods were used to elicit opinion from clinical experts where no evidence was available. These provide informed "priors" on key model parameters. A decision analytic model was developed to assess the costs and health consequences associated with the primary outcome of the trials over a lifetime time horizon. The main outcome measures were costs from a health service perspective and outcomes measured as quality-adjusted life-years (QALYs).
Results: The incremental cost-effectiveness ratio of EECP was 18,643 pound sterling for each additional QALY, with a probability of being cost-effective of 0.44 and 0.70 at cost-effectiveness thresholds of 20,000 pound sterling and 30,000 pound sterling per QALY gained, respectively. Results were sensitive to the duration of health-related quality of life (HRQoL) benefits from treatment.
Conclusions: The long-term maintenance of HRQoL benefits of EECP is central to the estimate of cost-effectiveness. The results from a single randomized control trial do not provide firm evidence of the clinical or cost-effectiveness of EECP in stable angina. Long-term follow-up trials assessing quality of life from EECP are required.

Ethnopharmacological Relevance: Shexiang Baoxin Pill (MUSKARDIA), a traditional Chinese patent medicine, plays a crucial role in both preventing and treating diverse cardiovascular diseases, including coronary heart disease, myocardial infarction (MI), and heart failure. Preclinical research has demonstrated that the cardioprotective effects of MUSKARDIA are achieved through multiple pathways, such as enhancing coronary artery dilation, fostering new blood vessel growth, reducing inflammation and oxidative stress, improving lipid metabolism, and protecting vascular endothelium.
Aim Of The Study: This subgroup analysis aimed to evaluate the efficacy and safety of Shexiang Baoxin Pill (MUSKARDIA) plus optimal medical therapy (OMT) across different weight categories in treating stable coronary artery disease (CAD).

: A Warthin tumor is a benign salivary gland neoplasm, mostly found in the parotid gland. The number of reported Warthin tumors has increased over the years due to better diagnostic modalities and health system modernization. Warthin tumor rarely transforms into a malignant tumor; in this work, we present all cases reported in the English literature of different types of lymphomas within Warthin tumors.

Background: Angina with non-obstructive coronary artery disease (ANOCA) is commonly observed in patients with stable angina undergoing coronary angiography. Current guidelines recommend non-invasive stress testing as the first step in diagnosing coronary microvascular disease (CMD). This study aims to evaluate the diagnostic value of non-invasive stress testing in patients invasively diagnosed with CMD.

Angina pectoris (AP), a clinical syndrome characterized by paroxysmal chest pain, is caused by insufficient blood supply to the coronary arteries and sudden temporary myocardial ischemia and hypoxia. Long-term AP typically induces other cardiovascular events, including myocardial infarction and heart failure, posing a serious threat to patient safety. However, AP's complex pathological mechanisms and developmental processes introduce significant challenges in the rapid diagnosis and accurate treatment of its different subtypes, including stable angina pectoris (SAP), unstable angina pectoris (UAP), and variant angina pectoris (VAP).
