Demographic and regional trends of peripheral artery disease-related mortality in the United States, 2000 to 2019

INTRODUCTION

Peripheral artery disease (PAD) is a common progressive atherosclerotic disease associated with significant morbidity and mortality in the US; however, data regarding PAD-related mortality trends are limited. This study aims to characterize contemporary trends in mortality across sociodemographic and regional groups.

METHODS

The Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research (CDC WONDER) was queried for data regarding PAD-related deaths from 2000 to 2019 in the overall sample and different demographic (age, sex, race/ethnicity) and regional (state, urban-rural) subgroups. Crude and age-adjusted mortality rates (CMR and AAMR, respectively) per 100,000 people were calculated. Associated annual percentage changes (APC) were computed using Joinpoint Regression Program Version 4.9.0.0 trend analysis software.

RESULTS

Between 2000 and 2019, a total of 1,959,050 PAD-related deaths occurred in the study population. Overall, AAMR decreased from 72.8 per 100,000 in 2000 to 32.35 per 100,000 in 2019 with initially decreasing APCs followed by no significant decline from 2016 to 2019. Most demographic and regional subgroups showed initial declines in AAMRs during the study period, with many groups exhibiting no change in mortality in recent years. However, men, non-Hispanic (NH) Black or African American individuals, people aged ⩾ 85 years, and rural counties were associated with the highest AAMRs of their respective subgroups. Notably, there was an increase in crude mortality rate among individuals 25-39 years of age from 2009 to 2019.

CONCLUSION

Despite initial improvement, PAD-related mortality has remained stagnant in recent years. Disparities have persisted across several demographic and regional groups, requiring further investigation.

Aspirin use is associated with decreased inpatient mortality in patients with COVID-19: A meta-analysis

Thromboembolism is a major cause of death in patients who suffer from COVID-19. Studies examining the effects of aspirin (ASA) on mortality relating to this phenomenon have showed conflicting results with varying degrees and certainties of evidence. We performed an aggregate data meta-analysis of fourteen studies encompassing 164,539 COVID-19 patients, which showed a reduced risk of in-hospital mortality associated with ASA use in eight studies that reported risk ratios (RR 0.90; 95 % CI 0.82-0.98; I² = 27.33 %, P = 0.01), six studies that reported hazard ratios (HR 0.56; 95 % CI 0.41-0.76, P ≤ 0.01; I² = 85.92 %) and pooled effect size (0.71; 95 % CI 0.59-0.85, P = 0.00, I² = 91.51 %). The objective of this study is to report the association between low dose ASA and a reduced risk of in-hospital mortality in patients with COVID-19.

Outcomes and Resource Utilization of Atrial Fibrillation Hospitalizations With Type 2 Myocardial Infarction

Scarce data exist on the prognostic impact of type 2 myocardial infarction (MI) in patients with AF. The Nationwide Readmission Database 2018 was queried for primary AF hospitalizations with and without type 2 MI. Complex samples multivariable logistic and linear regression models were used to determine the association between type 2 MI and outcomes (in-hospital mortality, index length of stay [LOS], hospital costs, discharge to nursing facility, and 30-day all-cause readmissions). Of 382,896 weighted primary AF hospitalizations included in this study, 7,375 (1.9%) had type 2 MI. AF with type 2 MI is associated with significantly higher in-hospital mortality (adjusted OR [aOR] 1.76; 95% CI 1.30 to 2.38), LOS (adjusted parameter estimate [aPE] 0.48; 95% CI 0.35 to 0.62), hospital costs (aPE 1307.75; 95% CI 986.05 to 1647.44), discharges to nursing facility (aOR 1.38; 95% CI 1.24 to 1.54), and 30-day all-cause readmissions (adjusted hazard ratio 1.17; 95% CI 1.07 to 1.27) compared to AF without type 2 MI. Heart failure, chronic kidney disease, neurologic disorders, and age (per year) were identified as independent predictors of mortality among AF patients with type 2 MI. In conclusion, type 2 MI in the setting of AF hospitalization is associated with high in-hospital mortality and increased resource utilization.

Modes of failure with fractional flow reserve guidewires: Insights from the manufacturer and user facility device experience database

BACKGROUND

Fractional flow reserve (FFR) measurement is commonly used in the cardiac catheterization laboratory to assess the functional significance of coronary arterial plaques. Robust real-world data on complications and modes of failure of FFR guidewires are limited.

AIM

To characterize these outcomes by analyzing the post-marketing surveillance data from the United States Food and Drug Administration Manufacturer and User Facility Device Experience (MAUDE) database for commonly used FFR guidewires.

METHODS

The MAUDE database was queried from January 2010 through April 2020 for 3 FFR guidewires [PressureWire^TM X (Abbott), Comet^TM (Boston Scientific), and Verrata^TM (Philips)] by searching for the following events: “Injury”, “malfunction”, “death”, and “other”. This yielded 544 reports. After excluding incomplete reports, 486 reports were analyzed.

RESULTS

Guidewire tip fracture was the most commonly reported mode of failure, in 174 (35.8%) cases followed by guidewire kinking (n = 152, 31.3%), communication failure (n = 141, 29.0%), and shaft fracture (n = 67, 13.8%). In total, 133 (27.4%) device failures resulted in patient adverse events. The most common adverse event was retained guidewire tip, in 71 (53.4%) cases, followed by freshly deployed stent dislodgment (n = 26, 19.6%) and coronary artery dissection (n = 23, 17.3%). Seven deaths were reported.

CONCLUSION

FFR guidewire failures can occur because of various mechanisms and cause patient adverse events. The MAUDE database serves as an important platform for improved collaboration among clinicians, device manufacturers, and regulators to improve device performance and optimize patient outcomes. Our analysis provides mechanistic insights of FFR guidewire failure and associated adverse events but cannot verify causality or provide a comparison among different guidewires.

Efficacy of Psychosocial Interventions in Inducing and Maintaining Alcohol Abstinence in Patients With Chronic Liver Disease: A Systematic Review

BACKGROUND & AIMS

We conducted a systematic review of efficacy of psychosocial interventions in inducing or maintaining alcohol abstinence in patients with chronic liver disease (CLD) and alcohol use disorder (AUD).

METHODS

We performed structured keyword searches in PubMed, PsychINFO, and MEDLINE for original research articles that were published from January 1983 through November 2014 that evaluated the use of psychosocial interventions to induce or maintain alcohol abstinence in patients with CLD and AUD.

RESULTS

We identified 13 eligible studies that comprised 1945 patients; 5 were randomized controlled trials (RCTs). Delivered therapies included motivational enhancement therapy, cognitive behavioral therapy (CBT), motivational interviewing, supportive therapy, and psychoeducation either alone or in combination in the intervention group and general health education or treatment as usual in the control group. All studies of induction of abstinence (4 RCTs and 6 observational studies) reported an increase in abstinence among participants in the intervention and control groups. Only an integrated therapy that combined CBT and motivational enhancement therapy with comprehensive medical care, delivered during a period of 2 years, produced a significant increase in abstinence (74% increase in intervention group vs 48% increase in control group, P = .02), which was reported in 1 RCT. All studies of maintenance of abstinence (1 RCT and 2 observational studies) observed recidivism in the intervention and control groups. Only an integrated therapy that combined medical care with CBT produced a significantly smaller rate of recidivism (32.7% in integrated CBT group vs 75% in control group, P = .03), which was reported from 1 observational study. However, data were not collected for more than 2 years on outcomes of patients with CLD and AUD.

CONCLUSIONS

In a systematic analysis of studies of interventions to induce or maintain alcohol abstinence in patients with CLD and AUD, integrated combination psychotherapy with CBT, motivational enhancement therapy, and comprehensive medical care increased alcohol abstinence. No psychosocial intervention was successful in maintaining abstinence, but an integrated therapy with CBT and medical care appears to reduce recidivism.

ST elevation: telling pathology from the benign patterns

Benefits of early reperfusion in patients presenting with acute ST elevation myocardial infarction (STEMI) are well known. The American College of Cardiology / American Heart Association guidelines recommend triage decisions are made within 10 minutes of performing initial electrocardiogram (ECG). Since many patients presenting with ischemic symptoms may have ST elevation (STE) at baseline, not all STE signify transmural ischemia. Benign patterns can be easy to find in some cases. However, patients with benign STE at baseline (left ventricular hypertrophy, early repolarization pattern) may have ongoing ischemia and present with Non-ST elevation myocardial infarction (NSTEMI) or even STEMI superimposed on the benign pattern. The ability of clinicians to distinguish between ischemic and non ischemic STE varies widely and is affected by prevalence of such changes in patient population. More studies need to be done to delineate the criteria to clearly distinguish between ischemic and non ischemic ST elevation.

The health seeking behaviour of elderly population in a poor-urban community of Karachi, Pakistan

OBJECTIVES

To presents socio-demographic characteristics and health seeking behaviour of elderly and to determine frequency of Diabetes Mellitus and Hypertension in elderly population of a poor peri-urban community in Karachi, Pakistan.

METHODS

A cross-sectional study was conducted, targeting population aged 65 or above. A total of 438 respondents were interviewed after taking informed consent, between November 2005 and December 2005. Frequencies and Chi square values were calculated for different variables using SPSS 13.0.

RESULTS

Total population surveyed comprised of 438 elderly, 158 (36%) women and 280 (63.9%) men. Mean age for the population was 71.44 +/- 7.74. A total of 238 (54.3%) elderly were found to be economically active. More than half (n = 269, 61.4%) of the elderly were found to be illiterate. Only 72 (16.4%) of the elderly population were Diabetic and 132 (30.1%) were Hypertensive. Common symptoms that prompted elderly of Azam Basti to seek health care were fever (61.2%), generalized body aches (43.4%) and cough (40.4%). Over half of the (n = 269, 61.4%) responders reported factors which deterred them from seeking health care, out of which 62% reported financial constraint as the commonest factor. Deterrence from seeking health care was associated with illiteracy (p = 0.001) and living alone (p = 0.06).

CONCLUSION

The elderly population of this peri-urban community has financial constraints in seeking health care. Hypertension was found to be more prevalent among women as compared to men, ratio being 1:2. Less number of people knew they were diabetics; this might be attributed to ignorance and non-availability of investigations and screening.
