Acute Coronary Syndrome: Unravelling the Biology to Identify New Therapies

Estimating the prevalence of depression in people with acute coronary syndromes: A systematic review and meta-analysis

BACKGROUND

The epidemic of acute coronary syndromes (ACS) poses a great challenge to depression. However, the prevalence of depression among ACS patients has not been fully determined. This meta-analysis aimed to provide an estimation of the global prevalence of depression among ACS patients (ACS depression).

METHODS

Online databases including PubMed, Cochrane Library, Web of Science, and Scopus were searched for all relevant studies that reported the prevalence of ACS depression through March 2023. Pooled prevalence of ACS depression with 95% confidence interval (CI) was estimated by the random-effect model. All statistical analyses were performed using comprehensive meta-analysis software. This review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) (identifier CRD42023409338).

RESULTS

A total of 28 studies (17 cohort studies, 9 cross-sectional studies, and 2 case-control studies) were included. The overall pooled prevalence of depression in ACS, derived from 28 studies, was 28.5% (95% CI: 0.28-0.29, P = .000, I2 = 99%). 21 included studies showed a prevalence of 20.3% (95% CI: 0.20-0.21, P = .000, I2 = 96%) in men, and the prevalence in women was 13.6% (95% CI: 0.13-0.14, P = .000, I2 = 95%). Subgroup analysis showed the lowest prevalence in Europe (20.7%, 95% CI: 0.20-0.22, P = .000, I2 = 98%); On different diagnostic criteria, the diagnostic and statistical manual of mental disorders (DSM-IV) (36.8%, 95% CI: 0.35-0.38, P = .000, I2 = 96%) has the highest prevalence. In terms of end year of data collection, the prevalence of ACS depression was lower for studies that ended data collection after 2012 (25.7%, 95% CI: 0.25-0.27, P = .000, I2 = 99%) than in studies before 2012 (30%, 95% CI: 0.29-0.31, P = .000, I2 = 98%).

CONCLUSION SUBSECTIONS

This systematic review and meta-analysis suggest high global prevalence of depression among ACS patients, underlining the necessity of more preventive interventions among ACS patients especially in Asian and North American regions.

Door-to-Balloon Time and Mortality Among Patients Undergoing Primary PCI, Challenges and Experience from Somalia's Largest PCI Center

Introduction

The door-to-balloon time, the time between a patient's arrival at the hospital and percutaneous coronary intervention, is crucial for managing myocardial infarction. Aiming for less than 90 minutes is recommended, as shortened times are associated with improved outcomes. However, limited healthcare resources, infrastructure, transportation and poverty impact management, leading to poorer outcomes and delayed door to balloon time. Addressing these challenges and their causes is essential for optimal care.

Methodology

A retrospective analysis of 103 patients' medical history records from May 2022 to June 2023 at the Mogadishu Somali Turkish Training and Research Hospital in Somalia was conducted. The data was mainly collected from the hospital's electronic medical records system, analyzing patient demographics, clinical characteristics, and angiographical records. The study analyzed variables responsible for door-to-balloon (D2B) time delay, patient angiography results, cause of delay, procedure length, etc.

Results

A study of 103 patients who had angiography performed between May 2022 and July 2023 was done. The predominant gender in the study was 73% male, with a mean age of 58 years. The most common risk factors were hypertension (33%), smoking (38%), and diabetes (39%). Of all the vessels, the Left Anterior Descending (LAD) was the most commonly obstructed (63%). Time delays from door-to-balloon were frequent, median door-to-balloon time was 169 minutes, frequently brought on by social problems and financial limitations. The majority (77.4%) of the patients had only percutaneous angiography (PCI), while 22.6% were recommended for bypass following PCI of the infarct-related artery (IRA). Complications in the delayed treatment group were the main cause of the death rate of 24.2%.

Conclusion

Door-to-balloon time is crucial for acute myocardial infarction treatment which is challenging in impoverished countries like Somalia. Investments in healthcare infrastructure, public health education, and emergency services can improve patient outcomes.
