What's the Risk? Older Women Report Fewer Symptoms for Suspected Acute Coronary Syndrome than Younger Women

Risk Factors for Early-Onset Versus Late-Onset Coronary Heart Disease (CHD): Systematic Review and Meta-Analysis

AIM

We aimed to systematically compare literature on prevalence of modifiable and non-modifiable risk factors for early compared to late-onset coronary heart disease (CHD).

METHODS

PubMed, CINAHL, Embase, and Web of Science databases were searched (review protocol registered in PROSPERO CRD42020173216). Study quality was assessed using the National Heart, Lung and Blood Institute tool for observational and case-control studies. Review Manager 5.3 was used for meta-analysis. Effect sizes were expressed as odds ratio (OR) and mean differences (MD)/standardised MD (SMD) with 95% confidence intervals (CI) for categorical and continuous variables.

RESULTS

Individuals presenting with early-onset CHD (age <65 years) compared to late-onset CHD had higher mean body mass index (MD 1.07 kg/m2; 95% CI 0.31-1.83), total cholesterol (SMD 0.43; 95% CI 0.23-0.62), low-density lipoprotein (SMD 0.26; 95% CI 0.15-0.36) and triglycerides (SMD 0.50; 95% CI 0.22-0.68) with lower high-density lipoprotein-cholesterol (SMD 0.26; 95% CI -0.42--0.11). They were more likely to be smokers (OR 1.76, 95% CI 1.39-2.22) and have a positive family history of CHD (OR 2.08, 95% CI 1.74-2.48). They had lower mean systolic blood pressure (MD 4.07 mmHg; 95% CI -7.36--0.78) and were less likely to have hypertension (OR 0.47, 95% CI 0.39-0.57), diabetes mellitus (OR 0.56, 95% CI 0.51-0.61) or stroke (OR 0.31, 95% CI 0.24-0.42).

CONCLUSION

A focus on weight management and smoking cessation and aggressive management of dyslipidaemia in young adults may reduce the risk of early-onset CHD.

Racial and Ethnic Disparities in Acute Coronary Syndrome: A Nationally Representative Sample

Background

Disparities in acute coronary syndrome (ACS) outcomes exist between racial and ethnic groups. We aimed to evaluate disparities in resource utilization and inpatient outcomes across multiple ethnic and racial groups using contemporary data.

Methods

We identified hospital discharges for ACS in the United States using the National Inpatient Sample from 2015 to 2018. The International Classification of Diseases, Tenth Revision, Clinical Modification codes were used to identify variables of interest. The primary outcomes were in-hospital complications, length of stay, and total hospital charge. Statistical analysis was performed using STATA version 17.

Results

Our analysis included 1,911,869 ACS discharges. Our sample was made up of 78.6% White, 12.1% Black, and 9.3% Hispanic patients. Hispanic and Black patients presenting with ACS were younger and had more cardiometabolic comorbidities than their White counterparts, especially hypertension, diabetes mellitus, and obesity. Despite social determinants of health being more likely to be unfavorable for Hispanics than their White counterparts, they were more likely to incur higher total hospital charges than their White counterparts. Black patients were the least likely to undergo revascularization procedures. Despite these differences, White patients had higher in-hospital mortality rates than Black and Hispanic patients.

Conclusions

In this nationally representative study, despite having higher cardiometabolic comorbidity burden, lower socioeconomic status, and percutaneous intervention, Black and Hispanic patients experienced lower mortality rates than their White counterparts. Hispanic patients incurred the highest amount of total hospital charges for an ACS admission.

The Lay Public's Knowledge of the Most Common Acute Coronary Syndrome Symptoms Experienced by Women and Men

BACKGROUND

Although extensive research and public education for the last 2 decades has focused on symptom differences experienced by men and women, little is known about what acute coronary syndrome symptoms the lay public associates with men, with women, and with both men and women.

OBJECTIVE

The aim of this study was to describe what acute coronary syndrome symptoms the lay public associates with men, with women, and with both men and women and to explore whether differences in participant gender affect how these symptoms are associated.

METHODS

A descriptive, cross-sectional survey design was used, using an online survey. We recruited women (n = 209) and men (n = 208) living in the United States from the crowdsourcing platform Mechanical Turk in April and May 2021.

RESULTS

Most participants (78.4%) selected a chest symptom as the most common acute coronary syndrome symptom experienced by men, compared with only 49.4% who selected a chest symptom as the most common for women. Almost half (46.9%) of women indicated that they believe men and women have "fairly different" or "very different" acute coronary syndrome symptoms, compared with 17.3% of men.

CONCLUSIONS

Whereas most participants associated symptoms with both men and women's experiences of acute coronary syndrome symptoms, some associated symptoms in ways that are not reflected in the literature. Additional research is needed to further understand the impact of messaging on acute coronary syndrome symptom differences between men and women and the lay public's interpretation of these messages.

Prevalence of Prolonged Length of Stay in an Emergency Department in Urban Denmark: A Retrospective Health Records Repository Review

INTRODUCTION

Prolonged length of stay in emergency departments is associated with increased hospitalization, hospital-acquired pressure ulcers, medication errors, and mortality. In acute admissions in Denmark in 2018, 67% of patients experienced waiting time from arrival to examination. This study aimed to estimate the prevalence of prolonged length of stay (≥6 hours) and identify risk factors related to input, throughput, and output components.

METHODS

A retrospective health records repository review included 4743 patients admitted to a single urban emergency department in Denmark in January 2019. Data collected from the electronic health record system repository included demographic and organizational characteristics and were analyzed using descriptive statistics and logistic regression.

RESULTS

Among patients admitted in the study period, 31% had a prolonged length of stay of ≥6 hours. Prolonged length of emergency department stay was associated with being female (male odds ratio [OR], 0.86; 95% confidence interval [CI], 0.75-0.98), treatment by medical service (OR, 4.25, 95% CI, 3.63-4.98) vs surgical or injury, triage acuity of 2-Orange (OR, 1.45; 95% CI, 1.18-1.78) or 3-Yellow (OR, 1.47; 95% CI, 1.23-1.75) on a 5-level scale, evening (OR, 1.44; 95% CI, 1.24-1.66) or night (OR, 2.36; 95% CI, 1.91-2.91) arrival, ages 56 to 80 (OR, 1.79; 95% CI, 1.52-2.11) and >81 (OR, 2.40; 95% CI, 1.99-2.88) years, and hospital admission (OR, 1.19; 95% CI, 1.04-1.38) vs discharge from the emergency department to home.

DISCUSSION

Female, elderly, and medical patients were each identified as at-risk characteristics for ≥6-hour length of stay in the emergency department. Acute care patient pathways in the emergency department, particularly for evening and night, with guideline-based care and system level improvements in patient flow are warranted. Further research with larger populations is needed to identify and support interventions to decrease prolonged length of stay.

Multimorbidity in Patients With Acute Coronary Syndrome Is Associated With Greater Mortality, Higher Readmission Rates, and Increased Length of Stay: A Systematic Review

OBJECTIVE

The aims of this systematic review were to determine the magnitude and impact of multimorbidity (≥2 chronic conditions) on mortality, length of stay, and rates of coronary intervention in patients with acute coronary syndrome (ACS) and to compare the prevalence of cardiovascular versus noncardiovascular multimorbidities.

METHODS

MEDLINE, PubMed, MedlinePlus, EMBASE, OVID, and CINAHL databases were searched for studies published between 2009 and 2019. Eight original studies enrolling patients with ACS and assessing cardiovascular and noncardiovascular comorbid conditions met the inclusion criteria. Study quality was evaluated using the Crowe Critical Appraisal Tool.

RESULTS

The most frequently examined cardiovascular multimorbidities included hypertension, diabetes, heart failure, atrial fibrillation, stroke/transient ischemic attack, coronary heart disease, and peripheral vascular disease; the most frequently examined noncardiovascular multimorbidities included cancer, anemia, chronic obstructive pulmonary disease, renal disease, liver disease, and depression. The prevalence of multimorbidity in the population with ACS is high (25%-95%). Patients with multimorbidities receive fewer evidence-based treatments, including coronary intervention and high-dose statins. Patients with multimorbidities experience higher in-hospital mortality (5%-13.9% vs 2.6%-6.1%), greater average length of stay (5-9 vs 3-4 days), and lower rates of revascularization (9%-14% vs 39%-42%) than nonmultimorbid patients. Women, despite being the minority in all sample populations, exhibited greater levels of multimorbidity than men.

CONCLUSIONS

Multimorbid patients with ACS are at a greater risk for worse outcomes than their nonmultimorbid counterparts. Lack of consistent measurement makes interpretation of the impact of multimorbidity challenging and emphasizes the need for more research on multimorbidity's effects on postdischarge healthcare utilization.

Cardiovascular Risk Reduction in Rural Women: A Literature Synthesis

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of death in most countries. Lack of awareness of the impact CVD has on women is a continuing problem. Rural women are at a great risk for CVD and have specific barriers to early recognition and to access to treatment.

OBJECTIVE

The purpose of this systematic review was to identify how the state of the science for rural women and CVD has progressed over the last decade.

METHODS

Searches were conducted using the databases Cochrane, PubMed, and CINAHL with 5 major subject headings. The search resulted in the identification of 571 articles. Specific exclusion criteria resulted in an in-depth review of 15 articles. Two of the authors reviewed each article for scientific merit and interrater reliability.

RESULTS

Most studies were conducted in the United States (67%). Four studies focused on CVD knowledge; one, on physical activity; one, on diet plus other factors; one, on the effect of dried curry leaf powder and cucumber slices on hyperlipidemia; and one each, on waist circumference, exposure to smoke from wood stoves, and social support. Five of the 15 studies focused on more than 1 component, most on diet and physical activity.

CONCLUSIONS

Depth in a body of knowledge on any 1 topic, such as the most efficacious means to decrease CVD risk factors in rural women and increase health promotion activities in the population, is lacking. Another area of concern is the lack of research articles published in cardiovascular journals that include CVD in rural women.

The association between symptom onset characteristics and prehospital delay in women and men with acute coronary syndrome

BACKGROUND

A decision to delay seeking treatment for symptoms of acute coronary syndrome increases the risk of serious complications, disability, and death.

AIMS

The purpose of this study was to determine if there was an association between gradual vs abrupt symptom onset and prehospital delay for patients with acute coronary syndrome and to examine the relationship between activities at symptom onset and gradual vs abrupt symptom onset.

METHODS

This was a secondary analysis of a large prospective multi-center study. Altogether, 474 patients presenting to the emergency department with symptoms of acute coronary syndrome were included in the study. Symptom characteristics, activity at symptom onset, and prehospital delay were measured with the ACS Patient Questionnaire.

RESULTS

Median prehospital delay time was four hours. Being uninsured (β=0.120, p=0.031) and having a gradual onset of symptoms (β=0.138, p=0.003) were associated with longer delay. A diagnosis of ST-elevation myocardial infarction (β=-0.205, p=0.001) and arrival by ambulance (β=-0.317, p<0.001) were associated with shorter delay. Delay times were shorter for patients who experienced an abrupt vs gradual symptom onset (2.57 h vs 8 h, p<0.001). Among men with an abrupt onset of symptoms and a ST-elevation myocardial infarction diagnosis, 54% reported that symptoms were triggered by exertion (p=0.046).

CONCLUSION

Patients should be counselled that a gradual onset of symptoms for potential acute coronary syndrome is an emergency and that they should call 911. Men with ischemic heart disease or with multiple risk factors should be cautioned that symptom onset following exertion may represent acute coronary syndrome.
