Comparison of in-hospital outcomes and complications of leadless pacemaker and traditional transvenous pacemaker implantation.

AIMS: Since their introduction in 1958, traditional cardiac pacemakers have undergone considerable upgrades over the years, but they continue to have a complication rate of ∼3.8%-12.4%. There are no randomized controlled trials comparing outcomes of leadless pacemakers (LPM) with single-chamber transvenous pacemakers (TV-VVI). The aim is to assess the differences in the procedural complications and in-hospital outcomes between LPM and TV-VVI implants. METHODS AND RESULTS: We queried the national inpatient database from 2016 to 2019 to include adult patients undergoing LPM and TV-VVI. Admissions for leadless and single-lead transvenous pacemakers were identified by their appropriate ICD-10 codes. Complications were identified using ICD-10 codes that mostly represent initial encounter. The difference in outcomes was assessed using multivariable logistic regression and 1:1 propensity score matching between the two cohorts. Thirty-five thousand four hundred thirty expanded samples of admissions were retrieved of which 27 650 (78%) underwent TV-VVI with a mean age 81.3 ± 9.4 years and 7780 (22%) underwent LPM with a mean age of 77.1 ± 12.1 years. The LPM group had a higher likelihood of in-hospital mortality [adjusted odds ratio (aOR): 1.63, 95% CI (1.29-2.05), P < 0.001], vascular complications [aOR: 7.54, 95% CI (3.21-17.68), P < 0.001], venous thromboembolism [aOR: 3.67, 95% CI (2.68-5.02), P < 0.001], cardiac complications [aOR: 1.79, 95% CI (1.59-2.03), P < 0.001], device thrombus formation [aOR: 5.03, 95% CI (2.55-9.92), P < 0.001], and need for a blood transfusion [aOR: 1.54, 95% CI (1.14-2.07), P < 0.005]. The TV-VVI group had higher likelihood of in-hospital pulmonary complications [aOR:0.68, 95% CI (0.54-0.87), P < 0.002] and had a need for device revisions [aOR:0.42, 95% CI (0.23-0.76), P < 0.004]. CONCLUSION: There is a higher likelihood of all-cause in-hospital mortality and complications following LPM implantation in comparison to TV-VVI. This could be related to higher co-morbidities in the LPM group. Clinical trials aimed to accurately compare these two groups should be undertaken.

The Influence of Urbanization on the Patterns of Hepatocellular Carcinoma Mortality From 1999 to 2020.

Background: Hepatocellular carcinoma (HCC) remains one of the leading causes of cancer-related fatalities despite early diagnosis and treatment progress, creating a significant public health issue in the United States. This investigation utilized death certificate data from the Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research (CDC WONDER) database to investigate HCC mortality patterns and death locations from 1999 to 2020. The objective was to analyze trends in HCC mortality across different population groups, considering the impact of urbanicity. Methods: In this study, death certificate data obtained from the CDC WONDER database were utilized to investigate the trends in HCC mortality and location of death between 1999 and 2020. The annual percent change (APC) method was applied to estimate the average annual rate of change during the specified timeframe for the relevant health outcome. Furthermore, including data on the location of death and geographic areas allowed us to gain deeper insights into the patterns and characteristics of HCC and its impact on different regions. Results: Between 1999 and 2020, there were 184,073 reported deaths attributed to HCC, and data on the location of death were available for all cases. Most deaths occurred during inpatient admissions (34.93%) or at home (41.19%). The study also found that the highest age-adjusted mortality rate (AAMR) for HCC was observed among male patients, particularly among those identified as Asian or Pacific Islander. Variations in AAMR were determined based on the level of urbanization or rurality of the area, with higher rates observed in more densely populated and urbanized regions. In contrast, less urbanized and populated areas experienced a profound increase in AAMR over the past two decades. Conclusion: The HCC-related AAMRs have worsened over time for most ethnic groups, except for Asian or Pacific Islanders, which showed a reduction in APC despite having the worst AAMR. Although rural and less densely populated areas have substantially increased AAMR over the past two decades, more urbanized areas continued to have higher AAMR rates.

Trends in Colorectal Cancer Mortality in the United States, 1999 - 2020.

Background: The United States faces a significant public health issue with colorectal cancer (CRC), which remains the third leading cause of cancer-related fatalities despite early diagnosis and treatment progress. Methods: This investigation utilized death certificate data from the Centers for Disease Control and Prevention Wide-Ranging OnLine Data for Epidemiologic Research (CDC WONDER) database to investigate trends in CRC mortality and location of death from 1999 to 2020. Additionally, the study utilized the annual percent change (APC) to estimate the average annual rate of change over the specific time period for the given health outcome. Incorporating the location of death in this study served the purpose of identifying patterns related to CRC and offering valuable insights into the specific locations where deaths occurred. Results: Between 1999 and 2020, there were 1,166,158 CRC-related deaths. The age-adjusted mortality rates (AAMRs) for CRC consistently declined from 20.7 in 1999 to 12.5 in 2020. Men had higher AAMR (18.8) than women (13.4) throughout the study. Black or African American patients had the highest AAMR (21.1), followed by White (15.4), Hispanic/Latino (11.8), American Indian or Alaska native (11.4), and Asian or Pacific Islanders (10.2). The location of death varied, with 41.99% at home, 28.16% in medical facilities, 16.6% in nursing homes/long-term care facilities, 7.43% in hospices, and 5.80% at other/unknown places. Conclusion: There has been an overall improvement in AAMR among most ethnic groups, but an increase in AAMR has been observed among white individuals below the age of 55. Notably, over one-quarter of CRC-related deaths occur in medical facilities.

Ticagrelor use in patients after percutaneous coronary intervention: one year follow up in a community hospital.

BACKGROUND: Current guidelines from American College of Cardiology (ACC) recommend ticagrelor over clopidogrel in patients with acute coronary syndrome. We have observed many patients being switched from ticagrelor to clopidogrel after percutaneous coronary intervention (PCI) in our hospital. Our goal is to evaluate the use rate of ticagrelor and categorize the reasons for non-use. METHODS: We performed a retrospective data analysis of all patients who underwent PCI at Unity Hospital of Rochester, New York, from January 2019 to January 2020. A total of 330 patients underwent PCI for ACS over the year. After exclusions, 277 patients were enrolled in the analysis. RESULTS: Of the 277 patients, 179 (65%) completed one year of ticagrelor therapy, and 98 (35%) stopped ticagrelor and transitioned to clopidogrel. The most common reason for switching from ticagrelor was dyspnea (42 patients), followed by cost concerns (41 patients). CONCLUSION: At our community hospital, completion of one-year use of ticagrelor post-PCI occurred in 65% of patients. The most common reasons for discontinuation are dyspnea and medication cost.
