Lung cancer is uncontrolled growth of cells that occurs due to exposure to smoke, radiation and chemicals, which causes chronic stress and associated with impaired autonomic nervous system. Nonlinear heart rate variability (HRV) analysis has been suggested to uncover the performance status of lung cancer subjects and distinguish them from healthy controls. The present work obtained tachogram from recorded electrocardiogram of 104 lung cancer subjects and 30 healthy controls to extract HRV indices. The obtained results suggested lowered HRV (altered autonomic nervous system tone) values from Eastern Cooperative Oncology Group (ECOG) 1 to ECOG4. Subject males had higher HRV measures than their female counterparts. The HRV parameters decreased from ECOG PS of 1 to 4. Control females had higher HRV measures than control males. There was no association between age and HRV measures. Statistically, nonlinear HRV features were observed significant. ANN exhibited ECOG1 83.3%, ECOG2 50%, ECOG3 90%, ECOG4 95% and Controls 86.7%. The prediction analysis using artificial neural network (ANN) and support vector machine (SVM) scoring an accuracy of 93.09% and 100% with nonlinear HRV indices as input thus has been suggested to be a tool of prognostic importance.

BACKGROUND: The most common aetiology of cardiogenic shock (CS) is acute coronary syndrome (ACS), but even up to 20%-50% of CS is caused by other disorders. ST-segment deviations in the electrocardiogram (ECG) have been investigated in patients with ACS-related CS, but not in those with other CS aetiologies. We set out to explore the prevalence of different ST-segment patterns and their associations with the CS aetiology, clinical findings and 90-day mortality. METHODS: We analysed the baseline ECG of 196 patients who were included in a multinational prospective study of CS. The patients were divided into 3 groups: (a) ST-segment elevation (STE). (b) ST-segment depression (STDEP). (c) No ST-segment deviation or ST-segment impossible to analyse (NSTD). A subgroup analysis of the ACS patients was conducted. RESULTS: ST-segment deviations were present in 80% of the patients: 52% had STE and 29% had STDEP. STE was associated with the ACS aetiology, but one-fourth of the STDEP patients had aetiology other than ACS. The overall 90-day mortality was 41%: in STE 47%, STDEP 36% and NSTD 33%. In the multivariate mortality analysis, only STE predicted mortality (HR 1.74, CI95 1.07-2.84). In the ACS subgroup, the patients were equally effectively revascularized, and no differences in the survival were noted between the study groups. CONCLUSION: ST-segment elevation is associated with the ACS aetiology and high mortality in the unselected CS population. If STE is not present, other aetiologies must be considered. When effectively revascularized, the prognosis is similar regardless of the ST-segment pattern in ACS-related CS.

Cíl: Cílem této studie bylo porovnat nastavení mezikomorového zpoždění pomocí trojrozměrné echokardiografie (3DE) s využitím systolic dyssynchrony indexu (SDI) oproti nastavení dle šíře komplexu QRS u nemocných s nově implantovaným biventrikulárním kardiostimulátorem (srdeční resynchronizační léčbou, SRL). Sledovali jsme vliv na redukci objemů levé komory (LK) a počet echokardiografických respondérů v odstupu šesti měsíců od implantace. Metodika: Do této randomizované otevřené studie bylo zařazeno 63 nemocných s nedávno implantovanou SRL. Nemocní byli rozděleni do dvou skupin dle způsobu nastavení mezikomorového zpoždění: v první skupině dle šíře komplexu QRS (n = 31) s cílem dosáhnout nejužšího komplexu QRS, ve 2. skupině pomocí SDI (n = 32) s cílem dosáhnout jeho nejnižší hodnoty. Nemocní před implantací SRL a po šesti měsících od implantace podstoupili 3DE vyšetření ke zhodnocení objemů levé komory (LK), ejekční frakce LK (EFLK) a SDI. Hodnotili jsme též klinickou odpověď a měřili koncentraci N-terminálního fragmentu natriuretického propeptidu typu B (NT-proBNP). Výsledky: Po šesti měsících nebyl zaznamenán signifikantní rozdíl v redukci end-systolického objemu LK (-33 ± 55 ml vs. -48 ± 43 ml, p = 0,367), ve zlepšení EFLK (+7,3 ± 10,9 % vs. +10,2 ± 9,4 %, p = 0,210), v klinické odpovědi a v poklesu koncentrace NT-proBNP mezi oběma skupinami. Počet echokardiografických respondérů byl v obou skupinách podobný (14 vs. 18, p = 0,612). Závěr: Individuální optimalizace mezikomorového zpoždění pomoci SDI nepřinesla v odstupu šesti měsíců oproti nastavení dle šíře komplexu QRS signifikantní zlepšení echokardiografických a klinických parametrů.

Aim: The aim of this study was to compare the setting of interventricular (VV) delay by 3D echocardiography (3DE) using systolic dyssynchrony index (SDI) versus QRS width measurement in new cardiac resynchronization therapy (CRT) recipients. We observed the impact on the reduction of left ventricle volumes and increase in volumetric responders (defined as a ≥15% reduction in left ventricular end-systolic volume (LVESv) at the 6-month follow-up. Methods: We included 63 patients with recently implanted CRT in this open-label, randomized trial. Patients were randomized into two groups. VV delay was set by the QRS width in the group 1 (n = 31) to obtain the narrowest QRS complex and by SDI in the group 2 (n = 32) to achieve the lowest possible value. We evaluated LVESv, left ventricular ejection fraction (LVEF) by 3DE, before CRT implantation and at 6-month follow-up, in all patients. We also obtained clinical parameters and the level of NT-proBNP. Results: The second group showed only a trend towards greater reduction of LVESv (-33 ± 55 ml vs. -48 ± 43 ml; p = 0.367), increase in LVEF (+7.3 ± 10.9% vs. +10.2 ± 9.4%; p = 0.210) and greater number of volumetric responders (14 vs. 18; p = 0.612) compared with the group 1 at 6-month follow-up. There were also no significant differences in clinical outcomes and the level of NT-proBNP. Conclusion: Individual CRT optimization using SDI compared with QRS duration assessment did not reveal any significant differences in echocardiographic parameters and clinical outcomes at 6-month follow-up.

INTRODUCTION: Most contemporary 12-lead electrocardiogram (ECG) devices offer computerized diagnostic proposals. The reliability of these automated diagnoses is limited. It has been suggested that incorrect computer advice can influence physician decision-making. This study analyzed the role of diagnostic proposals in the decision process by a group of fellows of cardiology and other internal medicine subspecialties. MATERIALS AND METHODS: A set of 100 clinical 12-lead ECG tracings was selected covering both normal cases and common abnormalities. A team of 15 junior Cardiology Fellows and 15 Non-Cardiology Fellows interpreted the ECGs in 3 phases: without any diagnostic proposal, with a single diagnostic proposal (half of them intentionally incorrect), and with four diagnostic proposals (only one of them being correct) for each ECG. Self-rated confidence of each interpretation was collected. RESULTS: Availability of diagnostic proposals significantly increased the diagnostic accuracy (p<0.001). Nevertheless, in case of a single proposal (either correct or incorrect) the increase of accuracy was present in interpretations with correct diagnostic proposals, while the accuracy was substantially reduced with incorrect proposals. Confidence levels poorly correlated with interpretation scores (rho≈2, p<0.001). Logistic regression showed that an interpreter is most likely to be correct when the ECG offers a correct diagnostic proposal (OR=10.87) or multiple proposals (OR=4.43). CONCLUSION: Diagnostic proposals affect the diagnostic accuracy of ECG interpretations. The accuracy is significantly influenced especially when a single diagnostic proposal (either correct or incorrect) is provided. The study suggests that the presentation of multiple computerized diagnoses is likely to improve the diagnostic accuracy of interpreters.

Kontext: Synkopa je důvodem pro 1–6 % hospitalizací. Evropské i americké doporučené postupy pro léčbu synkopy uvádějí dvanáctisvodový EKG záznam jako součást vyšetření všech pacientů s nevysvětlenou ztrátou vědomí. Cíle: Cílem této studie bylo posoudit význam EKG, 24hodinového holterovského monitorování EKG a koncentrací N-terminálního fragmentu natriuretického propeptidu typu B (NT-proBNP) při rozlišování pacientů s kardiální a reflexně zprostředkovanou synkopou. Metody: Za poslední tři roky jsme vyšetřili 100 pacientů (56 mužů) ve věku 18–77 let s reflexně zprostředkovanou nebo kardiální synkopou. Byly sledovány následující faktory: věk, pohlaví, systolický a diastolický tlak a přítomnost kardiovaskulárního onemocnění. Mimoto jsme hodnotili základní parametry klidového EKG záznamu a 24hodinového holterovského EKG monitorování a koncentrace NT-proBNP v diferenciální diagnostice synkopy. Výsledky: Pacienti s reflexní synkopou byli mladší než pacienti s kardiální synkopou (44,4 ± 16,5 vs. 60,8 ± 12,6 roku; p < 0,001). Patologický klidový 12svodový EKG záznam byl častěji nalezen ve skupině s kardiogenním typem synkopy – 12 (24 %) vs. 8 (16 %). Čtyřiadvacetihodinové holterovské EKG monitorování neprokázalo statisticky významný rozdíl mezi oběma skupinami v minimální, průměrné a maximální srdeční frekvenci. Statisticky významné rozdíly mezi hodnocenými skupinami byly nalezeny ve výskytu komorových a supraventrikulárních arytmií. Pacienti s kardiální synkopou měli významně vyšší koncentrace NT-proBNP než pacienti s reflexně zprostředkovanou synkopou (448,7 ± 212,2 vs. 68,2 ± 64,1; p < 0,0001). Závěry: U pacientů s kardiogenním mechanismem synkopy je přítomna zvýšená koncentrace NT-proBNP, přestože klidový EKG záznam nemá v tomto smyslu jednoznačně výpovědní hodnotu.

Background: Syncope is a cause of 1–6% of hospitalizations. Both European and American syncope guidelines recommend a 12-lead ECG as part of the evaluation of all patients with unexplained loss of consciousness. Objectives: The aim of this study was the assessment of the significance of ECG, Holter ECG and the concentration of NT-proBNP that would be useful in the differentiation of patients with cardiac and reflex syncope. Methods: We investigated 100 patients (56 men), aged 18–77 years with reflex or cardiac syncope over the last 3 years. The following factors were investigated: age, sex, systolic and diastolic blood pressure, the presence of cardiovascular disease. Moreover, we assessed basic resting ECG parameters and 24-hour Holter ECG parameters, and NT-proBNP concentration in the differential diagnosis of syncope. Results: Patients with reflex syncope were younger compared to patients with cardiac syncope (44.4 ± 16.5 vs. 60.8 ± 12.6; p < 0.001). A pathologic resting 12-lead ECG was present more frequently in the group with a cardiogenic type of syncope – 12 (24%) vs. 8 (16%). 24-hour Holter ECG monitoring showed no statistically significant difference between minimal, mean and maximal heart rates in the analyzed groups. However, statistically significant differences were observed in the occurrence of ventricular and supraventricular arrhythmias between the investigated groups. Patients with cardiac syncope had significantly higher concentrations of NT-proBNP compared to patients with reflex syncope (448.7 ± 212.2 vs. 68.2 ± 64.1; p < 0.0001). Conclusions: Elevated NT-proBNP concentration is present in patients with a cardiogenic mechanism of syncope, despite the fact that a resting ECG is inconclusive.

INTRODUCTION: The right ventricular myocardial infarction (RVMI) has traditionally been mainly related to inferior wall ST elevation myocardial infarction (STEMI). This study assessed the RVMI electrocardiographic (ECG-RVMI) signs in relationship to ECG-based STEMI localization and to the infarct related artery in patients treated with primary percutaneous coronary intervention (pPCI). METHODS: Three hundred consecutive adult patients (107 females) were referred to catheterization laboratory with the acute STEMI diagnosis. In all patients, both the standard 12-lead ECGs and the right-sided precordial leads (V1R-V6R) were recorded. ECG-RVMI was diagnosed by ST segment elevation above 100μV in V4R. RESULTS: ECG signs of RVMI were found in 35 and 31 (23.8% for both) patients with inferior and anterior wall STEMI, respectively. In 32 ECG-RVMI patients, the right coronary artery (RCA) was occluded while in 34 patients, the occlusions were in the left anterior descending (LAD) or the left circumflex artery. No statistically significant differences were found in ECG-RVMI patients when comparing clinical variables between those with anterior and inferior wall STEMI. CONCLUSIONS: ECG signs of RVMI during acute STEMI are not uncommon. RCA was the infarction-related artery in only one half of these patients. Anterior wall STEMI and the LAD were associated with a significant proportion of ECG-RVMI cases.

Článek přehledně shrnuje současný pohled na diagnostiku a léčbu stabilních forem ischemické choroby srdeční (ICHS). Pojem stabilní angina pectoris zahrnuje onemocnění řady pacientů, kteří jsou léčeni stejnými postupy, přestože jejich riziko pro vznik závažných kardiálních příhod je velmi rozdílné. Hlavním ukazatelem míry tohoto rizika je rozsah myokardiální ischémie. Proto je třeba všechny pacienty stratifikovat podle tohoto rizika (provedením selektivní koronarografie či zátěžové scintigrafie myokardu) a v případě, že rozsah ischémie přesahuje 10 % myokardu, je nutno volit spíše intervenční či chirurgickou léčbu. Ve farmakoterapii je třeba používat kombinace všech kategorií léčiv ovlivňujících ischémii myokardu. Jde o skupiny léčiv, jež zvyšují dodávku kyslíku do myokardu (nitráty, beta‑blokátory, dihydropyridiny), snižují spotřebu kyslíku v myokardu (beta‑blokátory, ivabradin, verapamil) či optimalizují metabolismus ischemického myokardu (trimetazidin). Tato léčba ischémie myokardu musí být doplněna léky ovlivňujícími koronární aterosklerózu (statiny) a snižujícími riziko vzniku intrakoronární trombózy (antiagregace).

This overview describes diagnostic and therapeutic approach to the stable forms of coronary artery disease. Label “stable” has been used for many patients with a different risk of development of major adverse cardiac events. Main predictor of such events is the extent of myocardial ischemia. Therefore it is necessary to stratify all stable patients according to this marker in conservative treatment. Interventional and surgical therapy should be chosen if the extent of myocardial ischemia is more than 10% of all myocardial mass. All types of conservative treatment influencing myocardial ischemia should be used. It means the drugs increasing myocardial perfusion (nitrates, beta‑blockers, dihydropyridines), decreasing myocardial oxygen consumption (beta‑blockers, ivabradine, verapamil) and improving metabolism of ischemic myocardium (trimetazidine). This kind of therapy should be combined with the drugs that can influence coronary atherosclerosis (statins) and decrease the risk of intracoronary thrombosis (antiaggregation).

BACKGROUND: The electrocardiogram (ECG) is the most commonly used diagnostic procedure for assessing the cardiovascular system. The aim of this study was to compare ECG diagnostic skill among fellows of cardiology and of other internal medicine specialties (non-cardiology fellows). METHODS: A total of 2900 ECG interpretations were collected. A set of 100 clinical 12-lead ECG tracings were selected and classified into 12 diagnostic categories. The ECGs were evaluated by 15 cardiology fellows and of 14 non-cardiology fellows. Diagnostic interpretations were classified as (1) correct, (2) almost correct, (3) incorrect, and (4) dangerously incorrect. Multivariate logistic regression was used to assess confounding factors and to determine the odds ratios for the months of experience, age, sex, and the distinction between cardiology and non-cardiology fellows. RESULTS: The mean rate of correct diagnoses by cardiology vs. non-cardiology fellows was 48.9±8.9% vs. 35.9±8.0% (p=0.001; 70.1% vs. 55.0% for the aggregate of 'correct' and 'almost correct' diagnoses). There were 10.2±5.6% of interpretations classified as 'dangerously incorrect' by cardiology fellows vs. 16.3±5.0% by non-cardiology fellows (p=0.008). The cardiology fellows achieved statistically significantly greater diagnostic accuracy in 7 out of the 12 diagnostic classes. In multivariable logistic regression, the distinction between cardiology and non-cardiology fellows was the only independent statistically significant (p<0.001) predictor of whether the reader is likely correct or incorrect. Being a non-cardiology fellow reduced the probability of correct classification by 42% (odds ratio [95% confidence interval]: 0.58 [0.50; 0.68]). CONCLUSIONS: Although cardiology fellows out-performed the others, skills in ECG interpretation were found not adequately proficient. A comprehensive approach to ECG education is necessary. Further studies are needed to evaluate proper methods of training, testing, and continuous medical education in ECG interpretation.

It has become increasingly apparent in recent years that there are important differences of many cardiovascular disorders including ventricular tachycardias in men and women. Nevertheless, so far just few studies have addressed possible gender differences in electrophysiological characteristics of idiopathic ventricular tachycardia from right ventricular outflow tract (RVOT-VT), other than epidemiological ones. This study explored possible gender differences in electrophysiological characteristics and catheter ablation outcome in RVOT-VT patients. Ninety-three patients (mean age 38.7+/-15.5 years, 30 males) with idiopathic RVOT-VT were enrolled and analyzed in our study. Male patients had longer QRS width (99.9+/-19.4 ms vs. 88.4+/-20.7 ms, p=0.02). Female patients had lower right ventricular mean voltage (3.0+/-0.7 mV vs. 3.7+/-0.9 mV, p=0.03), and more low voltage zone over the right ventricular outflow tract free wall (27.0 % vs. 6.7 %, p=0.02). Eighty-one patients passed catheter ablation (23 males). The acute success rate, repeated catheter ablation rate and VT recurrence rate were similar in both genders. The present study provides evidence of the gender differences in electrophysiological findings in patients with idiopathic RVOT-VT. Studies on gender-specific differences in arrhythmia could lead to a better understanding of its mechanism(s) and provide valuable information for the development of optimal treatment strategies.
