RESUMEN
BACKGROUND: Patients with chronic thromboembolic pulmonary hypertension (CTEPH) in countries with limited resources have, to date, been poorly represented in registries. OBJECTIVE: This work assesses the epidemiology, diagnosis, hemodynamic and functional parameters, and treatment of CTEPH in Russia, Kazakhstan, Turkey, Lebanon, and Saudi Arabia. METHODS: A prospective, cohort, phase IV, observational registry with 3-year follow-up (n = 212) in patients aged ≥ 18 years diagnosed with CTEPH was created. Clinical, hemodynamic, and functional parameters were obtained at an initial visit, follow-up visits, and a final visit at the end of 3 years' observation or end of follow-up. Data were recorded on electronic case report forms. Parameters evaluated included 6-minute walking distance (6MWD), use of pulmonary endarterectomy (PEA), balloon pulmonary angioplasty (BPA), pulmonary hypertension (PH)-targeted therapy, and survival. All statistical analyses were exploratory and descriptive, and were performed in the overall population. RESULTS: The most common symptoms were typical of those expected for CTEPH. Almost 90% of patients underwent right heart catheterization at diagnosis or initial study visit. In total, 66 patients (31%) underwent PEA before the initial visit; 95 patients (45%) were considered operable, 115 (54%) were inoperable, and two (1%) had no operability data. Only 26 patients (12%) had been assessed for BPA at their initial visit. PH-targeted therapy was documented at diagnosis for 77 patients (36%), most commonly a phosphodiesterase type 5 inhibitor (23%). Use of PH-targeted therapy increased to 142 patients (67%) at the initial visit, remaining similar after 3 years. Use of riociguat increased from 6% of patients at diagnosis to 38% at 3 years. Between baseline and end of observation, results for patients with paired data showed an increase in 6MWD. Survival at the end of observation was 88%. CONCLUSIONS: These data highlight the current diagnosis and management of CTEPH in the participating countries. They show that early CTEPH diagnosis remains challenging, and use of off-label PH-targeted therapy is common. CLINICALTRIALS: gov: NCT02637050; registered December 2015.
RESUMEN
BACKGROUND: The smoking paradox has been a matter of debate for acute myocardial infarction patients for more than two decades. Although there is huge evidence claiming that is no real paradox, publications supporting better outcomes in post-MI smokers are still being released. OBJECTIVE: To explore the effect of smoking on very long-term mortality after ST Elevation myocardial infarction (STEMI). METHODS: This study included STEMI patients who were diagnosed between the years of 2004-2006 at three tertiary centers. Patients were categorized according to tobacco exposure (Group 1: non-smokers; Group 2: <20 package*years users, Group 3: 20-40 package*years users, Group 4: >40 package*years users). A Cox regression model was used to estimate the relative risks for very long-term mortality. P value <0.05 was considered as statistically significant. RESULTS: There were 313 patients (201 smokers, 112 non-smokers) who were followed-up for a median period of 174 months. Smokers were younger (54±9 vs. 62±11, p: <0.001), and the presence of cardiometabolic risk factors were more prevalent in non-smokers. A univariate analysis of the impact of the smoking habit on mortality revealed a better survival curve in Group 2 than in Group 1. However, after adjustment for confounders, it was observed that smokers had a significantly increased risk of death. The relative risk became higher with increased exposure (Group 2 vs. Group 1; HR: 1.141; 95% CI: 0.599 to 2.171, Group 3 vs Group 1; HR: 2.130; 95% CI: 1.236 to 3.670, Group 4 vs Group 1; HR: 2.602; 95% CI: 1.461 to 4.634). CONCLUSION: Smoking gradually increases the risk of all-cause mortality after STEMI.
FUNDAMENTO: O paradoxo do fumante tem sido motivo de debate para pacientes com infarto agudo do miocárdio (IM) há mais de duas décadas. Embora haja muitas evidências demonstrando que não existe tal paradoxo, publicações defendendo desfechos melhores em fumantes pós-IM ainda são lançadas. OBJETIVO: Explorar o efeito do fumo na mortalidade de longo prazo após infarto do miocárdio por elevação de ST (STEMI). MÉTODOS: Este estudo incluiu pacientes com STEMI que foram diagnosticados entre 2004 e 2006 em três centros terciários. Os pacientes foram categorizados de acordo com a exposição ao tabaco (Grupo 1: não-fumantes; Grupo 2: <20 pacotes*anos; Grupo 3: 2-040 pacotes*anos; Grupo 4: >40 pacotes*anos). Um modelo de regressão de Cox foi utilizado para estimar os riscos relativos para mortalidade de longo prazo. O valor de p <0,05 foi considerado como estatisticamente significativo. RESULTADOS: Trezentos e treze pacientes (201 fumantes e 112 não-fumantes) foram acompanhados por um período médio de 174 meses. Os fumantes eram mais novos (54±9 vs. 62±11, p: <0,001), e a presença de fatores de risco cardiometabólicos foi mais prevalente entre os não-fumantes. Uma análise univariada do impacto do hábito de fumar na mortalidade revelou uma curva de sobrevivência melhor no Grupo 2 do que no Grupo 1. Porém, após ajustes para fatores de confusão, observou-se que os fumantes tinham um risco de morte significativamente maior. O risco relativo tornou-se maior de acordo com a maior exposição (Grupo 2 vs. Grupo 1: RR: 1,141; IC95%: 0,599 a 2.171; Grupo 3 vs. Grupo 1: RR: 2,130; IC95%: 1,236 a 3,670; Grupo 4 vs. Grupo 1: RR: 2,602; IC95%: 1,461 a 4,634). CONCLUSÃO: O hábito de fumar gradualmente aumenta o risco de mortalidade por todas as causas após STEMI.

OBJECTIVE: Different parameters on electrocardiograms (ECG) have been investigated to predict arrhythmia and mortality in patients with acute pulmonary embolism (APE). The acute effect of thrombolytic therapy (TT) on these parameters has not been investigated yet. METHODS: We examined the data of 83 patients who were evaluated as high-risk APE and discharged from the hospital after TT. First, the high-risk APE patients' ECGs were compared with healthy control subjects (n = 55). After their admission and 24 hours later, the ECGs of patients with APE were compared. Heart rate, P-wave morphology, QRS duration, QT distance, Tp-e, and the index of cardiac electrophysiological balance (iCEB) were analyzed. RESULTS: Although P maximum was not different between the groups' ECGs, heart rate, QT, QTc (corrected QT) interval, Tp-e intervals, Tp-e/QT ratio, and P wave dispersion were significantly higher in the APE group ( P values < 0.031). iCEB or iCEBc (corrected iCEB) values were lower in APE group ( P < 0.001). After TT, we determined a decrease in heart rate, Tp-e interval, and Tp-e/QT ratio ( P < 0.001). Although we detected a decrease in the QT and QTc interval and QT dispersion (QTd), QTd had no statistical significance (respectively P -value 0.013, 0.029, and 0.096). The iCEB and iCEBc levels were lower after TT ( P -value was 0.035 and 0.044 respectively). CONCLUSION: The QT, QTc, Tp-e interval, Tp-e/QTc ratio, iCEB, and iCEBc values significantly decreased after TT. It may be thought that effective TT causes partial improvement in ventricular repolarization in an early period.

RESUMO OBJETIVO: Diferentes parâmetros de eletrocardiograma (ECG) têm sido investigados para predizer mortalidade e arritmia em pacientes com embolia pulmonar aguda (EPA). O efeito agudo da terapia trombolítica (TT) nesses parâmetros ainda não foi investigado. MÉTODOS: Examinamos os dados de 83 pacientes avaliados com EPA de alto risco e que receberam alta hospitalar após TT. Primeiramente, comparamos os ECGs dos pacientes com EPA de alto risco com os de indivíduos saudáveis (n = 55). Os ECGs dos pacientes com EPA foram comparados logo após a internação e 24 horas mais tarde. A frequência cardíaca, a morfologia da onda P, a duração do QRS, o intervalo QT, Tp-e e o índice de equilíbrio eletrofisiológico cardíaco (iCEB) foram analisados. RESULTADOS: Embora o valor máximo de P não tenha sido diferente entre os grupos no ECG, a frequência cardíaca, QT, intervalo QTc (QT corrigido), intervalos Tpe, razão TP-e/QT e dispersão da onda P foram significativamente mais elevados no grupo de EPA (valores de P < 0,031). Os valores do iCEB ou iCEBc (iCEB corrigido) foram inferiores no grupo de APE (P < 0,001). Após a TT, observamos uma diminuição da frequência cardíaca, do intervalo TP-e e da razão TP-e/QT ( P < 0,001). Apesar de termos observado uma diminuição do intervalo QT e QTc e da dispersão do QT (QTd), o valor de QTd não apresentou uma diferença estatisticamente significativa (respectivamente, valor de P 0,013, 0,029 e 0,096). Os níveis do iCEB e iCEBc foram menores após a TT (valor de P 0,035 e 0,044, respectivamente). CONCLUSÃO: Os valores de QT, QTc, intervalo Tp-e, razão Tp-e/QTc, iCEB e iCEBc diminuíram significativamente após TT. Pode-se concluir que a TT eficaz causa uma melhora parcial da repolarização ventricular no período inicial.

OBJECTIVE: Depression and anxiety disorders are frequently found in combination with obstructive coronary artery disease. Coronary artery ectasia (CAE) is an atypical form of coronary artery disease, the etiology of which has not yet been clearly defined. The aim of this study was to assess the existence of a relationship between anxiety/depression and CAE. METHODS: A CAE group (n=41; mean age: 58.9±9.0 years) and a control group (n=42; mean age: 58.0±9.6 years) were compared. The anxiety and depression status of patients was evaluated using the Hospital Anxiety and Depression Scale (HADS) questionnaire. RESULTS: Age, sex, ejection fraction, and cardiovascular risk factor data were similar in both groups. The serum Creactive protein (CRP) and uric acid levels as well as the leukocyte count were significantly higher in the CAE group (p<0.05). The HADS anxiety score was higher in the CAE group, but without statistical significance (p=0.23). The HADS depression score and total HADS score was significantly higher in the CAE group (p<0.001 and p<0.001). The total HADS score and the HADS depression score were correlated with the serum CRP level (r=0.489; p<0.001 and r=0.543; p<0.001, respectively), whereas the anxiety score was not correlated with CRP (r=0.85; p=0.23). CONCLUSION: The depression score, CRP, and uric acid levels were greater in patients with isolated CAE compared with those of patients with normal coronaries. The anxiety score did not demonstrate a relationship to CAE; however, there was an association between the depression score and CRP, which is an inflammatory marker.

Transfemoral aortic valve implantation has become an almost routine interventional procedure for severe aortic stenosis in high-risk patients. Over time an increased number of experiences has led to unusual procedures. In this report, we present a successful valve-in-valve transfemoral aortic valve implantation in a patient with aortic regurgitation, who previously had debranching and thoracic endovascular aortic repair operations.

Increased sympathetic activity and endothelial dysfunction are the proposed mechanisms underlying exaggerated blood pressure response to exercise (EBPR). However, data regarding heart rate behavior in patients with EBPR are lacking. We hypothesized that heart rate recovery (HRR) could be impaired in patients with EBPR. A total of 75 normotensive subjects who were referred for exercise treadmill test examination and experienced EBPR were included to this cross-sectional case-control study. The control group consisted of 75 age- and gender-matched normotensive subjects without EBPR. EBPR was defined as a peak exercise systolic blood pressure (BP) ≥210 mmHg in men and ≥190 mmHg in women. HRR was defined as the difference in HR from peak exercise to 1 min in recovery; abnormal HRR was defined as ≤12 beats/min. These parameters were compared with respect to occurrence of EBPR. Mean values of systolic and diastolic BP at baseline, peak exercise, and the first minute of the recovery were significantly higher in the subjects with EBPR. Mean HRR values were significantly lower (P < 0.001) in subjects with EBPR when compared with those without. Pearson's correlation analysis revealed a significant positive correlation between the decrease in systolic BP during the recovery and degree of HRR in individuals without EBPR (r = 0.42, P < 0.001). Such a correlation was not observed in subjects with EBPR (r = 0.11, P = 0.34). The percentage of abnormal HRR indicating impaired parasympathetic reactivation was higher in subjects with EBPR (29 % vs 13 %, P = 0.02). In logistic regression analyses, HRR and resting systolic BP were the only determinants associated with the occurrence of EBPR (P = 0.001 and P < 0.001, respectively). Decreased HRR was observed in normotensive individuals with EBPR. In subjects with normal BP response to exercise, a linear correlation existed between the degree of HRR and decrease in systolic BP during the recovery period. However, such a correlation was not found in subjects with EBPR. Our data suggest that mechanisms underlying the blunting of the HRR might be associated with the genesis of EBPR. The association between the extent of HRR and adverse cardiovascular outcomes in patients with EBPR needs to be investigated in detail in future research.

BACKGROUND: The prevalence of smoking is high in Turkey. However, there are no data available evaluating the differences between smokers and nonsmokers according to their sex in patients with acute myocardial infarction (AMI) in Turkey. HYPOTHESIS: The aim of the study was to determine the prevalence of smoking and its relationship to age, localization, and extension of coronary heart disease (CHD), and other risk factors in Turkish men and women with first AMI. METHODS: This study included, 1502 patients with first AMI from 3 different cities in Turkey. The baseline characteristics and traditional risk factors for CHD, Coronary angiographic results, and in-hospital outcome were recorded. RESULTS: The proportion of male smokers was significantly higher than that of women (68% vs 18%, P < 0.001). Smokers were younger by almost a decade than nonsmokers (P < 0.001). Male nonsmokers were younger than females; however, the mean age of first AMI was similar in male and female smokers. In both genders, prevalence of hypertension and diabetes mellitus was significantly lower in smokers than in nonsmokers (P < 0.001). Smokers had less multivessel disease and less comorbidity as compared to nonsmokers. Although the in-hospital mortality rate was lower in smokers, smoking status was not an independent predictor of mortality. CONCLUSIONS: Smoking, by decreasing the age of first AMI in women, offsets the age difference in first AMI between men and women. The mean age of first AMI is lower in Turkey than most European countries due to a high percentage of smoking.

Amanita phalloides is responsible for the majority of the fatalities caused by mushroom poisoning. It causes damage in liver, kidneys and rarely pancreas, causing encephalopathic coma, disseminated intravascular coagulation, hemorrhage and hypovolemic shock. However, its effect on cardiac functions has not been established yet. In this case report, we aimed to present a female patient poisoned by A. phalloides mushroom complicated with multi-organ failure and cardiogenic shock due to advanced left ventricular systolic dysfunction. This case report was the first to show a successful treatment of cardiogenic shock due to mushroom poisoning with intra-aortic balloon counterpulsation, whereas she did not respond to other therapies.

A 84-year-old man presented to the emergency department complaining of chest pain and palpitations. He had no history of coronary artery disease. The 12-lead electrocardiography showed bidirectional ventricular tachycardia (BVT). Coronary angiography revealed severe mid left anterior descending and mid left circumflex lesions. The BVT, in this case, was most likely due to myocardial ischema. The ethiology of published BVT cases are most commonly digitalis toxicity and rarely herbal aconitine poisoning, hypokalemic periodic paralysis, cathecolaminergic VT, myocarditis, and Anderson-Tawil syndrome. The patient had neither of these underlying conditions. To the best of our knowledge and research in the literature, there was no report of bidirectional VT in the patients with myocardial infarction.

BACKGROUND: To determine the individual effect of abnormalities in blood pressure (BP) circadian rhythm (non-dipping status (NDS), increased morning BP (MBP) or increased MBP surge (MBPS)) on target organ damage (TOD) and which of these is more closely related to TOD in normotensives. METHODS AND RESULTS: The 24-h ambulatory BP monitoring (ABPM) and echocardiography were performed and urinary albumin excretion (UAE) was measured in 47 dipper (28 women, mean age 45.8 +/- 9.3) and 32 non-dipper (25 women, mean age 49.1 +/- 8.3 years) normotensive subjects. The left ventricular mass index (LVMI) was higher in non-dipper group (103.8 +/- 24.1 vs 91.6 +/- 23.5 g/m2, P=0.03). UAE in non-dipper group was higher, but the difference between the two was not statistically significant (18.9 [10.3, 28.9] vs 14.1 [7.5, 23.8], P=0.11). In multivariate analysis, both LVMI and UAE were affected by NDS and MBP independent of other confounding variables (for LVMI; Coefficient =0.27, P=0.01 and Coefficient =0.37, P=0.001, respectively, and for UAE; Coefficient =0.27, P=0.02 and Coefficient =0.28, P=0.01, respectively). CONCLUSIONS: It may be postulated that increased night and MBP are the factors that cause TOD, and it seems reasonable to attempt to restore normal diurnal rhythm of the BP even in normotensive subjects.

OBJECTIVE: There is not enough available data in our country about the prevalence of risk factors for ST-elevation myocardial infarction (STEMI), which has the highest in-hospital mortality rate within subtypes of acute coronary syndromes. Therefore, in this study, we aimed to evaluate the prevalence of risk factors for STEMI in Central Anatolia, one of the regions with high risk for coronary heart disease (CHD). METHODS: This cross-sectional observational study included 1210 patients (962 men, 248 women) with the diagnosis of STEMI in 3 tertiary-medical centers in 3 cities in Central-Anatolia (Ankara, Konya, and Kayseri). Demographic characteristics (age, gender) and risk factors known to be traditional risk factors for CHD (history of hypertension (HT), diabetes mellitus (DM), smoking, and family history) were inquired and fasting blood samples within 24 hours from onset of STEMI were taken to analyze lipid levels. Patients were divided into 3 groups based on their ages: Group A--age = or <44 years; Group B--age 45-64 years; and Group C--age = or >65 years. Prevalence of risk factors and differences within age-groups and genders were evaluated. RESULTS: The mean age was 58+/- 11 years (range 24-96 years). Although the percentage of female patients increased in relation to increasing age, 80% of the total patients were male. While prevalence of smoking and family history was observed to decrease with aging, there was a statistically significant increase in prevalence of HT and DM (p<0.001). Prevalence of smoking was the highest in young patients and males (p<0.001). Prevalence of HT and DM, on the other hand, was significantly higher in women than in men (p<0.001). Although the number of modifiable risk factors was found to be significantly smaller in men, male patients with STEMI were 8 years younger than females on average. CONCLUSIONS: The results of our study, in which modifiable risk factors and especially smoking were found to have a high prevalence in patients with STEMI living in Central Anatolia, suggested that most STEMI cases especially at younger ages might be prevented by the modification of these risk factors.

This study was planned to investigate the normal reference values of myocardial performance index (MPI) obtained by tissue Doppler echocardiography (TDE) and the agreement between MPI measured by TDE and conventional MPI measured by pulsed-wave Doppler (PWD) in healthy subjects and patients with heart failure (HF). Two hundred and three patients with HF and 190 healthy subjects were enrolled in this study. Isovolumic contraction and relaxation time (ICT and IRT) and ejection time (ET) were measured from mitral inflow and left ventricular (LV) outflow. Tissue Doppler echocardiography recordings were obtained at the septal, lateral, inferior, and anterior of the mitral annulus and same time intervals were measured. Myocardial performance index was calculated. The functional capacity of the patients with HF was determined according to New York Heart Association classification. TDE-MPI values were higher than conventional PWD-MPI values in both groups (53%+/-8% vs 48%+/-11%, P<0.0001 in the healthy subjects; 84%+/-21% vs 72%+/-19%, P<0.0001 in the patients with HF). Moderate agreement was found between PWD-MPI and LV mean TDE-MPI in both groups. In identifying patients with moderately or severely decreased LV ejection fraction, TDE-MPI had higher cutoff values than conventional PWD-MPI, and TDE-MPI had higher specificity, sensitivity, negative predictive value, and diagnostic accuracy. In patients with HF, TDE-MPI had a stronger correlation with LV ejection fraction and functional capacity than did PWD-MPI. TDE-MPI is an alternative to conventional PWD-MPI in assessment of cardiac function. However, the higher MPI cutoff points should be considered when this method is used for the evaluation of cardiac function.

The aim of this study is to evaluate the effect of type 2 diabetes mellitus on epicardial coronary flow velocity assessed by the thrombolysis in myocardial infarction frame count. The thrombolysis in myocardial infarction frame count was measured in 272 coronary arteries from 101 patients with type 2 diabetes mellitus and in 271 coronary arteries from 104 age- and gender-matched patients without type 2 diabetes mellitus referred for coronary angiography. The thrombolysis in myocardial infarction frame count was measured only in normal arteries or in arteries without significant lesion. By both univariate and multivariate analysis, the thrombolysis in myocardial infarction frame count was not related with either type 2 diabetes mellitus or the duration and glycated hemoglobin levels in the patients with type 2 diabetes mellitus. The thrombolysis in myocardial infarction frame count was significantly associated with body surface area, heart rate, and proximal coronary artery diameter. Type 2 diabetes mellitus did not affect epicardial coronary flow velocity assessed by the thrombolysis in myocardial infarction frame count.
