[PMID: 35743653 PMCID: PMC9225281 DOI: 10.3390/jpm12060869] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 05/12/2022] [Accepted: 05/23/2022] [Indexed: 02/05/2023] Open
Abstract
Electronic health records naturally contain most of the medical information in the form of doctor’s notes as unstructured or semi-structured texts. Current deep learning text analysis approaches allow researchers to reveal the inner semantics of text information and even identify hidden consequences that can offer extra decision support to doctors. In the presented article, we offer a new automated analysis of Polish summary texts of patient hospitalizations. The presented models were found to be able to predict the final diagnosis with almost 70% accuracy based just on the patient’s medical history (only 132 words on average), with possible accuracy increases when adding further sentences from hospitalization results; even one sentence was found to improve the results by 4%, and the best accuracy of 78% was achieved with five extra sentences. In addition to detailed descriptions of the data and methodology, we present an evaluation of the analysis using more than 50,000 Polish cardiology patient texts and dive into a detailed error analysis of the approach. The results indicate that the deep analysis of just the medical history summary can suggest the direction of diagnosis with a high probability that can be further increased just by supplementing the records with further examination results.

Prevalence, management and outcomes of cardiac tamponade complicating 66,812 invasive cardiac procedures: single-center clinical registry. ADVANCES IN INTERVENTIONAL CARDIOLOGY 2021; 17:193-199. [PMID: 34400922 PMCID: PMC8356823 DOI: 10.5114/aic.2021.107499] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Accepted: 03/06/2021] [Indexed: 11/17/2022] Open
Abstract
Introduction There are numerous studies concerning iatrogenic cardiac tamponade. Those studies are predominantly focused on one cardiac procedure and the follow-up is not always presented. Aim To estimate the rate of cardiac tamponade following 66,812 percutaneous invasive cardiac interventions depending on the procedure. For each group the baseline characteristics and hospital management, as well as in-hospital, 30-day and 1-year mortality, were evaluated. Material and methods The study was a single-center retrospective analysis performed in a tertiary clinical hospital, which encompasses two cardiology departments, assessing a large sample of patients who underwent percutaneous invasive cardiac procedures complicated with cardiac tamponade between January 2006 and December 2018. For this purpose, medical records and hospital databases were analyzed. Long-term follow-up was obtained in cooperation with the Silesian Cardiovascular Base. Results The rate of iatrogenic cardiac tamponade during the 13-year period was 0.176%. The incidence among selected invasive cardiac procedures ranged between 0.09% and 1.42%. The majority of cases (104/118) were treated by pericardiocentesis, 16 had pericardiotomy and 4 patients had both therapies. Inotropes were used in 25–45%, blood transfusion in 45% of patients. The highest in-hospital mortality was observed in patients with cardiac tamponade after transcatheter aortic valve implantation. The highest 30-day and 1-year mortality rates were seen in the group with temporary electrode pacing. Conclusions The low incidence of cardiac tamponade with the high number of patients requiring intensive care supply and high in-hospital mortality tend to confirm that cardiac tamponade is a rare but life-threatening complication.

Multivessel Intervention in Myocardial Infarction with Cardiogenic Shock: CULPRIT-SHOCK Trial Outcomes in the PL-ACS Registry. J Clin Med 2021; 10:jcm10091832. [PMID: 33922373 PMCID: PMC8122818 DOI: 10.3390/jcm10091832] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 04/03/2021] [Accepted: 04/19/2021] [Indexed: 11/24/2022] Open
Abstract
Background: The aim of the study was a comparison of culprit-lesion-only (CL-PCI) with the multivessel percutaneous coronary intervention (MV-PCI) in terms of 30-day and 12-month mortality in a national registry. Methods: Patients from the PL-ACS registry with MI and CS were analyzed. Patients meeting the criteria of the CULPRIT-SHOCK trial were divided into two groups: CL-PCI and MV-PCI groups. Results: Of the 3265 patients in the PL-ACS registry with MI complicated by CS, the criteria of the CULPRIT-SHOCK trial were met by 2084 patients (63.8%). The CL-PCI was performed in 883 patients, and MV-PCI was performed in 1045 patients. After the propensity score matching analysis, 617 well-matched pairs were obtained. In a 30-day follow-up, death from any cause occurred in 49.3% in the CL-PCI group and 57.0% in the MV-PCI group (RR 0.86, 95% CI 0.58–0.92, p = 0.0081). After 12 months, the rate of mortality was 62.5% in the CL-PCI group and 68.0% in the MV-PCI group (RR 0.92, 95% CI 0.84–1.01, p = 0.066). Conclusions: The results confirm the validity of CULPRIT-SHOCK findings in a national registry and current guideline-recommended strategy of revascularization limited to the infarct-related artery.

Cardiol J 2018; 27:566-574. [PMID: 30444257 DOI: 10.5603/cj.a2018.0140] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Revised: 09/08/2018] [Accepted: 10/11/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Despite the introduction of the concept known as "Chain of Survival" has significantly increased survival rates in patients with out-of-hospital cardiac arrest (OHCA), short-term mortality in this group of patients is still very high. Epidemiological data on OHCA in Poland are limited. The aim of this study was to create a prospective registry on OHCA covering a population of 2.7 million inhabitants of Upper Silesia in Poland. Presented herein is the study design and results of a 3-month pilot study. METHODS The Silesian Registry of Out-of-Hospital Cardiac Arrest (SIL-OHCA) is a prospective, population-based registry of OHCA, of minimum duration which was planned for 12 months; from January 1st, 2018 to December 31st, 2018. The first 3 months of the study constituted the pilot phase. The inclusion criterion is the occurrence of OHCA in the course of activity of the Voivodeship Rescue Service in Katowice, Poland. RESULTS During the 3-month pilot phase of the study there were 390 cases of OHCA in which cardiopulmonary resuscitation was undertaken. Estimated frequency of OHCA in the population analyzed was 57 per 100,000 population per year. Shockable rhythm was present in 25.8% of cases. Return of spontaneous circulation was achieved in 35.1% of the whole cohort. 28.7% of patients were admitted to the hospital, including 2.8% of patients, who were admitted during an ongoing cardiopulmonary resuscitation. CONCLUSIONS Prehospital survival of patients with OHCA in Poland is still unsatisfactory. It is believed that data collected in SIL-OHCA registry will allow identification factors, which require improvement in order to reduce short- and long-term mortality of patients with OHCA.

Temporal changes in the pattern of invasive angiography use and its outcome in suspected coronary artery disease: implications for patient management and healthcare resources utilization. ADVANCES IN INTERVENTIONAL CARDIOLOGY 2018; 14:247-257. [PMID: 30302100 PMCID: PMC6173087 DOI: 10.5114/aic.2018.78327] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2018] [Accepted: 09/04/2018] [Indexed: 12/18/2022] Open
Abstract
INTRODUCTION Invasive coronary angiography (CAG), the 'gold standard' in coronary artery disease (CAD) diagnosis, requires hospitalization, is not risk-free, and engages considerable healthcare resources. AIM To assess recent (throught out 10 years) evolution of 'significant' (≥ 50% stenosis(es)) CAD prevalence in subjects undergoing CAG for CAD diagnosis in a high-volume tertiary referral center. MATERIAL AND METHODS Anonymized medical records were compared for the last vs. the first 2-years of the decade (June 2007 to May 2018). Referrals for suspected CAD were 2067 of 4522 hospitalizations (45.7%) and 1755 of 5196 (33.8%) respectively (p < 0.001). RESULTS The median patient age (64 vs. 68 years) and the prevalence of heart failure (24.1% vs. 42.2%) increased significantly (p < 0.001). The CAG atherosclerotic lesions, for all stenosis categories (< 50%; ≥ 50%; ≥ 70%; occlusion(s)), were significantly more prevalent in men. The proportion of subjects with any atherosclerosis on CAG increased (80.7% vs. 77.6%, p = 0.015). However, in the absence of any gross change in, for instance, the fraction of women (40.4% vs. 41.8%), the proportion of CAGs with significant CAD (lesion(s) ≥ 50%) decreased from 55.2% in 2007/2008 to below 1 in every 2 angiograms (48.9%) in 2017/2018 (p < 0.001). This unexpected finding occurred consistently across nearly all CAG referral categories. CONCLUSIONS Despite more advanced age and a higher proportion of subjects with 'any' coronary atherosclerosis on CAG, the likelihood of a 'negative' angiogram (lesion(s) < 50%; no further evaluation/intervention) has increased significantly over the last decade. The exact nature of this phenomenon requires further investigation, particularly as a reverse trend would be expected with the growing role (and current high penetration) of contemporary non-invasive diagnostic tools to rule out significant CAD.

Abstract
AIMS To compare coronary artery bypass grafting (CABG) with percutaneous coronary interventions (PCI) in patients with heart failure with reduced ejection fraction (HFrEF) and multivessel coronary artery disease. METHODS 1213 patients were selected from institutional databases, 761 and 452 in CABG and PCI group respectively. Only the subjects with left ventricle ejection fraction ≤ 35% and multivessel coronary artery disease were included to the study. The primary outcome measure was long-term all-cause death, the secondary outcomes were recurrent myocardial infarction, urgent repeat revascularization and stroke. Propensity Score-Based Adjusted Survival Curves were used for revascularization methods comparison. RESULTS Survival rates were similar in both groups (HR, 0.91; 95% CI, 0.65-1.28; p=0.59). Recurrent myocardial infarction was observed significantly less often in the CABG group (HR, 0.44; 95% CI, 0.26-0.74; p=0.002). Repeat urgent revascularization was less frequent in the CABG group (HR, 0.50; 95% CI, 0.30-0.84; p=0.008). The rate of stroke did not differ between the groups (HR, 1.17; 95% CI, 0.62-2.22; p=0.62). CONCLUSIONS In patients with HFrEF and multivessel CAD revascularization both with CABG and PCI resulted in similar survival rates. PCI is associated with increased risk of recurrent MI and urgent repeat revascularization, whereas the risk of stroke is similar in both methods.

Abstract
BACKGROUND Poland, classified as a high-income country, is still considered to have a high cardiovascular risk population. During the last decade, the standards of care in acute stroke (AS) had markedly improved; thus, we aimed to assess whether and how it translated into early and late outcomes. METHODS Silesian Stroke Registry was created from the administrative database of the public, obligatory, health -insurer in Poland. The AS cases were selected based on primary diagnosis coded in ICD-10 as I60-I64 for years 2006-2015 (n = 120,844). Index hospitalization together with data on re-hospitalizations, procedures, ambulatory visits, rehabilitation and all-cause deaths in a 1-year follow-up were analyzed. RESULTS The rates of admissions per 100,000 adult population varied between 41-47 for haemorrhagic and 257-275 for ischaemic stroke with substantial decrease in almost all age groups except for the oldest patients. In ischaemic stroke, thrombolytic therapy raised from 0 to 8.8% in 2015, along with significant trends of decreasing 30-day (from 20 to 16%) and 12-month (from 35 to 31%) case fatality. In haemorrhagic stroke, case fatality had not changed. After ischaemic stroke, 12-month readmissions due to AS declined from 11-12% in 2006-2009 to 9% in 2010-2014. The percentage of patients benefiting from rehabilitation increased from 24 to 32%. CONCLUSIONS In a large population of industrial province, we showed recent, positive trends in AS admissions, treatment and 1-year outcomes. Development of stroke unit networks and increase in thrombolytic treatment were at least in part responsible for survival improvement and reduction of recurrence of AS. However, case-fatality and stroke recurrence remain high compared to those of other developed countries.

[PMID: 28740853 PMCID: PMC5504927 DOI: 10.1155/2017/8196256] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/23/2017] [Revised: 03/27/2017] [Accepted: 05/04/2017] [Indexed: 11/23/2022]
Abstract
Prothrombotic fibrin clot phenotype, involving faster formation of dense meshwork composed of thinner and highly branched fibers that are relatively resistant to plasmin-induced lysis, has been reported in patients with not only myocardial infarction or stroke, but also venous thromboembolism (VTE), encompassing deep vein thrombosis (DVT), and/or pulmonary embolism (PE). Prothrombotic fibrin clot phenotype, in particular prolonged clot lysis time, is considered a novel risk factor for VTE as well as venous thrombosis at unusual location, for example, cerebral sinus venous thrombosis, retinal vein obstruction, and Budd-Chiari syndrome. Growing evidence from observational studies indicates that abnormal fibrin clot properties can predict recurrent DVT and PE and they are involved in serious complications of VTE, for example, thromboembolic pulmonary hypertension and postthrombotic syndrome. The purpose of this article is to review our current understanding of the role of fibrin clot structure and function in venous thrombosis with emphasis on clinical issues ranging from prognosis to therapy.
