Challenges in Implementation of Institutional Protocols for Patients With Acute Coronary Syndrome

Causal relationship between Alzheimer's disease and unstable angina: a bidirectional Mendelian randomization analysis

Background

Research from observational studies has demonstrated a link between Alzheimer's disease (AD) and a higher risk of cardiovascular disease (CVD). Uncertainty surrounds the exact genetic cause of AD and coronary heart disease, particularly unstable angina (UA). Mendelian randomization (MR) analysis was used to examine the causal genetic link between AD and UA to evaluate the impact of AD on UA.

Methods

The purpose of the bidirectional MR analysis was to investigate the link between exposure and illness causation. Genetic instrumental variables for AD were obtained from European populations using genome-wide association studies (GWAS). The primary causal conclusions were obtained using the inverse variance weighted approach (IVW), and other sensitivity analysis techniques were employed. Sensitivity analyses were carried out to evaluate heterogeneity and horizontal pleiotropy to guarantee accurate MR results.

Results

An elevated risk of UA was linked to genetically predicted AD (IVW: OR=3.439, 95% CI: 1.565-7.555, P=0.002). A substantial genetic relationship between UA and the risk of AD was not supported by any evidence in the reverse study (IVW: OR=0.998, 95% CI: 0.995-1.001, P=0.190). Various MR techniques produced consistent results. Sensitivity analysis revealed no discernible heterogeneity or horizontal pleiotropy.

Conclusions

One risk factor for UA that we found in our bidirectional Mendelian randomization trial was AD. This highlights the necessity of researching the underlying molecular mechanisms linked to AD and UA as well as the possibility of creating individualized treatment plans based on genetic data.

Management of patients with acute ST-segment elevation myocardial infarction in Russian hospitals adheres to international guidelines

Objective

Russia has one of the highest cardiovascular mortality rates. Modernisation of the Russian health system has been accompanied by a substantial increase in uptake of percutaneous coronary intervention (PCI), which substantially reduces the risk of mortality in patients with acute ST-elevation myocardial infarction (STEMI). This paper aims to describe contemporary Hospital treatment of acute STEMI among patients in a range of hospitals in the Russian Federation.

Methods

This study used data from a prospective observational cohort of 1128 suspected patients with myocardial infarction recruited in both PCI and non-PCI hospitals across 13 regions and multiple levels of the health system in Russia. The primary objective was to examine the use of reperfusion strategies in patients with STEMI.

Results

Among patients reaching PCI centres within 12 hours of symptom onset, the vast majority received angiography and PCI, regardless of age, sex and comorbidity, in line with current European Society of Cardiology guidelines.

Conclusion

Patients reaching Russian hospitals are very likely to receive appropriate treatment, although performance varies. The best hospitals can serve as beacons of good practice as PCI facilities continue to expand across Russia where geography allows.

Assessing Performance and Quality After Non-ST Segment Elevation Acute Coronary Syndromes

PURPOSE OF REVIEW

This review summarizes and discusses the evidence base supporting current performance and quality measures used in assessing institutions in their care of patients with non-ST segment elevation acute coronary syndromes (NSTE-ACS).

RECENT FINDINGS

Professional societies in the USA and Europe have developed performance and quality measures for NSTE-ACS. These measures are reviewed and updated periodically to reflect the most important evidence from the literature. In the USA, the ACC/AHA Task Force on Performance Measures published the updated 2017 AHA/ACC Clinical Performance and Quality Measures for Adults With ST-Elevation and Non-ST-Elevation Myocardial Infarction. In Europe, the ESC Acute Cardiac Care Association published the 2017 Quality Indicators for acute myocardial infarction. These documents build on guidelines previously developed and published by the two organizations. They include detailed reviews of current and past studies establishing that adherence with guidelines improves clinical outcomes. Both measure sets provide quantitative methodologies to assess program performance. Institutional programs that focus on these validated measures can increase guideline adherence, streamline and standardize care processes, and reduce morbidity and mortality. Performance and quality measures have become a critical part of healthcare today, allowing patients, providers, administrators, and payors to assess patient care objectively. They are also becoming an important component of value-based payment programs. To be fair, and useful, for internal institutional assessment, in comparing different institutions, and for value-based payments, only validated performance measures such as these should be employed.
