Additional data from clinical examination on site significantly but marginally improve predictive accuracy of the Revised Trauma Score for major complications during Helicopter Emergency Medical Service missions

Introduction: The Revised Trauma Score (RTS) accurately identifies trauma patients at high risk of adverse events or death. Less is known about its usefulness in the general population and non-trauma recipients of Helicopter Emergency Medical Service (HEMS). The RTS is a simple tool and omits a lot of other data obtained during clinical evaluation. The aim was to assess the role of the RTS to identify patients at risk of major complications (death, cardiopulmonary resuscitation, defibrillation, intubation) in the general population of HEMS patients. Clinical factors beyond the RTS were analyzed to identify additional prognostic factors for predicting major complications. Material and methods: A retrospective analysis of medical records of adult patients routinely collected during HEMS missions in the years 2011-2014 was performed. Results: The analysis included 19 554 HEMS missions. Patients were 55 ±20 years old and 68% were male. The most common indication for HEMS was diseases of the circulatory system - 41%. Major complications occurred in 2072 (10.6%) cases. In the general population of HEMS patients, the RTS accurately identified individuals at risk of major complications at a cut-off value of 10.5 and area under the curve (AUC) of 93.5%. In multivariate analysis, additional clinical data derived from clinical examination (ECG; skin, pupil and breathing examination) significantly but marginally improved the accuracy of RTS assessment: AUC 95.6% (p < 0.001 for the difference). Conclusions: The Revised Trauma Score accurately identifies individuals at risk of major complications during HEMS missions regardless of the indication. Additional clinical data significantly but marginally improved the accuracy of RTS in the general population of HEMS patient

Statement by a Working Group conceived by the Polish National Consultants in Cardiology and Neurology addressing the use of implantable cardiac monitors in patients after ischaemic embolic stroke of undetermined source

Introduction. Stroke remains one of the main causes of death and the most common cause of long-term disability in adults. Embolic strokes of undetermined source (ESUS) amount to a significant proportion of all ischaemic strokes. Detection of atrial fibrillation (AF) in this group of patients would allow for a major therapeutic decision to switch from antiplatelets to oral anticoagulants and therefore significantly reduce the risk of recurrence. State of the Art. Current technology allows long-term continuous ECG monitoring with different systems, including implantable cardiac monitors (ICM). However, in Poland lack of reimbursement does not allow their use in everyday clinical practice. Clinical Implications. This is a statement by a Working Group conceived by the Polish National Consultants in Cardiology and Neurology addressing the use of ICM in patients after ischaemic embolic strokes of undetermined source. The aim was to develop reasonable and comprehensive guidance on how to select and manage candidates for ICM in order to obtain the maximum benefit for Polish public health. Future Directions. This expert opinion is not intended as a guideline but it provides advice as to how to optimise the potential use of ICM in patients after ESUS in the Polish setting

Novel algorithm for arrhythmogenic focus localization in patients with right ventricular outflow tract arrhythmias

Background: Previously presented new electrocardiography (ECG) algorithm for localization of arrhythmogenic focus (AFo) in right ventricular outflow tract (RVOT) was based on spontaneous arrhythmia QRS morphology analysis. The aim of this study was to estimate the clinical value of our RVOT algorithm in a prospective study.Methods and results: Algorithm validation was made on 62 patients with RVOT arrhythmias (45 women), mean age 41.6 ± 14.3 years, scheduled for transcatheter ablation. Results of preablation ECG analysis with RVOT algorithm were matched with successful ablation sites and statistical indices: sensitivity (sens), specificity (spec), and positive and negative predictive values (PPV, NPV) were calculated for algorithm and for each of 9 RVOT zones (septal and free wall). An algorithm precisely localized AFo in 57 out of 62 patients (sens 91.3%, spec 99%, PPV 91%, NPV 98.8%). Sensitivity values for superior RVOT aspect (71% patients) varied from 88% to 100%, specificity from 95.9% to 100%; PPV values from 85.7% to 100%, NPV from 92.5% to 100%. Although the total number of patients was relatively small in the 2 remaining RVOT aspects (29% patients) high values (sens, spec, PPV, NPV) were gained for intermediate and inferior zones.Conclusions: On the basis of spontaneous arrhythmia QRS analysis, a novel algorithm was built for preablation localization of RVOT arrhythmia in 1 of the 9 RVOT zones. Prospective analysis of our ECG algorithm confirmed that it is a valuable tool to predict the site of successful ablation in patients with RVOT arrhythmias.

Multimorbid management in atrial fibrillation: The Polish perspective in the EHRA-PATHS study

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia and places a significant burden on individuals as well as the healthcare system. AF management requires a multidisciplinary approach in which tackling comorbidities is an important aspect. AIMS: To evaluate how multimorbidity is currently assessed and managed and to determine if interdisciplinary care is undertaken. METHODS: A 21-item online survey was undertaken over four weeks as part of the EHRA-PATHS study examining comorbidities in Atrial Fibrillation and distributed  to European Heart Rhythm Association members in Europe. RESULTS: A total of 341 eligible responses were received of which 35 (10%) were from Polish physicians. Compared to other European locations, the rates of specialist services and referrals varied but were not significantly different. However, there were higher numbers of specialised services reported in Poland compared to the rest of Europe for hypertension (57% vs. 37%;  P = 0.02) and palpitations/arrhythmias (63% vs. 41%; P = 0.01) and the rates of sleep apnea services tended to be lower (20% vs. 34%; P = 0.10) and comprehensive geriatric care (14% vs. 36%; P = 0.01). The only statistical difference between Poland and the rest of Europe in reasons for referral rates was the barrier relating to insurance and financial reasons (31% vs. 11%; P &lt;0.01, respectively). CONCLUSIONS: There is a clear need for an integrated approach to patients with AF and associated comorbidities. Prepardeness of Polish physicians to deliver such care seems to be similar to other European countries but may be hampered by financial obstacles

Implantable cardioverter-defibrillators in patients with long QT syndrome: a multicentre study

Background: Implantable cardioverter-defibrillator (ICD) therapy has been proven effective in the prevention of sudden cardiac death, but data on outcomes of ICD therapy in the young and otherwise healthy patients with long QT syndrome (LQTS) are limited. Aim: We sought to collect data on appropriate and inappropriate ICD discharges, risk factors, and ICD-related complications. Methods: All LQTS patients implanted with an ICD in 14 centres were investigated. Demographic, clinical, and ICD therapy data were collected. Results: The study included 67 patients (88% female). Median age at ICD implantation was 31 years (12–77 years). ICD indication was based on resuscitated cardiac arrest in 46 patients, syncope in 18 patients, and malignant family history in three patients. During a median follow-up of 48 months, 39 (58%) patients received one or more ICD therapies. Time to first appropriate discharge was up to 55 months. Inappropriate therapies were triggered by fast sinus rhythm, atrial fibrillation, and T-wave oversensing. No predictors of inappropriate shocks were identified. Risk factors for appropriate ICD therapy were: (1) recurrent syncope despite b-blocker treatment before ICD implantation, (2) pacemaker therapy before ICD implantation, (3) single-chamber ICD, and (4) noncompliance to b-blockers. In 38 (57%) patients, at least one complication occurred. Conclusions: ICD therapy is effective in nearly half the patient population; however, the rates of early and late complica­tions are high. Although the number of unnecessary ICD shocks and reimplantation procedures may be lowered by modern programming and increased longevity of newer ICD generators, other adverse events are less likely to be reduced

Position of the Polish Cardiac Society on therapeutic targets for LDL cholesterol concentrations in secondary prevention of myocardial infarctions

Cardiovascular diseases account for 43% of deaths in Poland. The COVID-19 pandemic increased the number of cardiovascular deaths by as much as 16.7%. Lipid metabolism disorders are observed in about 20 million Poles. Lipid disorders are usually asymptomatic, they cause a significant increase in the risk of cardiovascular diseases. Up to 20% of patients who experience an acute coronary syndrome (ACS) may experience a recurrence of a cardiovascular event within a year, and up to 40% of these patients may be re-hospitalized. Within 5 years after a myocardial infarction, 18% of patients suffer a second ACS and 13% have got a stroke. Lipid-lowering therapy is an extremely important element of comprehensive management, both in primary and secondary prevention, and its main goal is to prevent or extend the time to the onset of heart or vascular disease and reduce the risk of cardiovascular events. A patient with a history of ACS belongs to the group of a very high risk of a cardiovascular event due to atherosclerosis. In this group of patients, low-density lipoprotein cholesterol levels should be aimed below 55 mg/dl (1.4 mmol/l). Many scientific guidelines define the extreme risk group, which includes not only patients with two cardiovascular events within two years, but also patients with a history of ACS and additional clinical factors: peripheral vascular disease, multivessel disease (multilevel atherosclerosis), or multivessel coronary disease, or familial hypercholesterolemia, or diabetes with at least one additional risk factor: elevated Lp(a) &gt;50 mg/dl or hsCRP &gt;3 mg/l, or chronic kidney disease (eGFR &lt;60 ml/min/1.73 m2). In this group of patients, the LDL-C level should be aimed at below 40 mg/dl (1.0 mmol/l). Achieving therapeutic goals in patients after ACS should occur as soon as possible. For this purpose, a high-dose potent statin should be added to the therapy at the time of diagnosis, and ezetimibe should be added if the goal is not achieved after 4–6 weeks. Combination therapy may be considered in selected patients from the beginning. After 4–6 weeks of combination therapy, if the goal is still not achieved, adding a proprotein convertase subtilisin/kexin type 9 protein inhibitor or inclisiran should be considered. In order to increase compliance with the recommendations, Polish Cardiac Society and Polish Lipid Society propose to attach in the patient’s discharge letter a statement clearly specifying what drugs should be used and what LDL-C values should be achieved. It is necessary to cooperate between the patient and the doctor, to follow the recommendations and take medicines regularly, to achieve and maintain therapeutic goals

In Heart Failure Patients with Left Bundle Branch Block Single Lead MultiSpot Left Ventricular Pacing Does Not Improve Acute Hemodynamic Response To Conventional Biventricular Pacing. A Multicenter Prospective, Interventional, Non-Randomized Study.

Introduction Recent efforts to increase CRT response by multiSPOT pacing (MSP) from multiple bipols on the same left ventricular lead are still inconclusive. Aim The Left Ventricular (LV) MultiSPOTpacing for CRT (iSPOT) study compared the acute hemodynamic response of MSP pacing by using 3 electrodes on a quadripolar lead compared with conventional biventricular pacing (BiV). Methods Patients with left bundle branch block (LBBB) underwent an acute hemodynamic study to determine the %change in LV+dP/dtmax from baseline atrial pacing compared to the following configurations: BiV pacing with the LV lead in a one of lateral veins, while pacing from the distal, mid, or proximal electrode and all 3 electrodes together (i.e. MSP). All measurements were repeated 4 times at 5 different atrioventricular delays. We also measured QRS-width and individual Q-LV durations. Results Protocol was completed in 24 patients, all with LBBB (QRS width 171±20 ms) and 58% ischemic aetiology. The percentage change in LV+dP/dtmax for MSP pacing was 31.0±3.3% (Mean±SE), which was not significantly superior to any BiV pacing configuration: 28.9±3.2% (LV-distal), 28.3±2.7% (LV-mid), and 29.5±3.0% (LV-prox), respectively. Correlation between LV+dP/dtmax and either QRS-width or Q-LV ratio was poor. Conclusions In patients with LBBB MultiSPOT LV pacing demonstrated comparable improvement in contractility to best conventional BiV pacing. Optimization of atrioventricular delay is important for the best performance for both BiV and MultiSPOT pacing configurations. Trial Registration ClinicalTrials.gov NTC0188314

A practical approach to the ESC 2022 cardio-oncology guidelines. Comments by a team of experts: cardiologists and oncologists

The 2022 European Society of Cardiology (ESC) guidelines [1] are a comprehensive document, prepared jointly by experts in cardiology and oncology. In the case of an oncological patient, it is necessary to individualize care in relation to the cardiological condition, the stage of the cancer and the type of potential anti-cancer therapy. Cardiac care optimisation should be undertaken before the start of oncological therapy, and continued during oncological therapy, as well as long-term after its completion [2]. The published ESC Guidelines were supplemented with a practical comments of a team of polish cardiology and oncology experts
