Background. Coronary artery disease (CAD) is one of the main causes of cardiovascular death. The severity of CAD is determined by the left ventricular (LV) dysfunction which is caused by coronary atherosclerosis. The possibility of restoring functional capacity of the heart (ejection fraction (EF)) depends on hibernating volume of the myocardium which is a pitfall in revascularization. The aim. To assess the correlation between the score of the viable myocardium (VM) and EF with systolic dysfunction and preserved LVEF in patients after coronary artery bypass grafting (CABG). Material and methods. To implement the set clinical tasks, 62 patients with CAD with preserved systolic function and systolic dysfunction were examined, 35 (56%) patients had heart failure with an EF of 49% (group 2) and less. Twenty-seven (44%) patients had preserved ventricular function of 50% or more (group 1). The mean age of the subjects was 59.6 ± 8.2 years. Five (8.0%) patients denied myocardial infarction. Myocardial scintigraphy was performed on Infinia Hawkeye all purpose imaging system (GE, USA) with integrated CT. The studies were performed in SPECT and SPECT/CT with ECG synchronization (gated SPECT) modes. 99mTc-MIBI with an activity of 555–740 MBq was used. Myocardial scintigraphy was performed in the course of treatment (before CABG and after CABG) according to the One Day Rest protocol. A total of 124 scintigraphic studies were performed. Results and discussion. Samples of the studied patients “before” and “after” treatment were compared using Wilcoxon matched-pairs test. In group 1 in patients with EF ≥ 50% the score of VM increased after CABG with values from 81.7 CI 95% [78.5; 84.9] to 86.9 CI 95% [84.4; 89.3]. However, the EF itself before and after treatment remained the same or slightly decreased amounting to 54.9 CI 95% [50.8; 59.1] and 52.5 CI 95% [48.6; 56.3]. In group 2 in patients with EF ≤ 49% the amount of VM increased after CABG with values from 59.9 CI 95% [54.9; 64.8] to 65.9 CI 95% [60.2; 71.6] (p = 0.00005). However, the EF itself before and after treatment remained the same, amounting to 28.9 CI 95% [24.8; 32.9] and 31.1 CI 95% [26.8; 35.5] (p = 0.19). Conclusions. Myocardial viability in both study groups significantly improved, given the high statistical reliability of the results, although LVEF either remained unchanged or changed slightly. Improvement of static parameters (wall perfusion) also confirms positive effect of revascularization with constant dynamic parameters (EF, end-diastolic volume) or statistically insignificant changes thereof. There is no direct correlation between VM and EF.

Introduction: Diastolic dysfunction has been characterized in relation to the relaxation and compliance properties of the left ventricle; limited information exists regarding its relationship to systolic function as assessed by deformation imaging. Objectives: To determine if there is left ventricular systolic dysfunction detected by global longitudinal strain (GLS) measured by two dimensional speckle tracking echocardiography in patients with immunoglobulin light chain (AL) amyloidosis with different degrees of diastolic dysfunction and normal ejection fraction (EF). Methods: Consecutive biopsy-proven AL patients with preserved EF (≥ 55%) who had a comprehensive echocardiogram performed and strain analysis were included. Cohort was divided into 5 groups according to the different grades of diastolic dysfunction: Group 0: normal filling pressures; Group 1: abnormal relaxation; Group 2: pseudo-normal pattern; Group 3: reversible restrictive; Group 4: fixed restrictive. Images were acquired and performed on a Vivid 9 from the 3 apical views, and analyzed on vendor-specific software (Echo-PAC, GE). GLS was averaged from the 16 segments, and their means compared by ANOVA and each pair with Student’s t test. Results: A total of 858 patients were included, mean age was 63.7 years ± 10.1, and 61.5% were male. From those, 205 (24%) were in group 0; 299 (35%) in group 1; 255 (30%) in group 2; 65 (7%) in group 3; and 34 in group 4 (4%). GLS means measurements were -18.95 ± 2.4, -16.86 ± 3.4, -15.60 ± 3.9, -12.31 ± 3.0, and -10.48 ± 3.3, respectively (P<0.0001). All individual GLS values were significantly different statistically when compared between each group (P<0.01 for all pairs; figure). Conclusions: Longitudinal systolic mechanical function is progressively impaired in AL amyloid patients as diastolic dysfunction progresses, despite normal EF. This systolic dysfunction provides insights into the intrinsic relationship between the components of the cardiac cycle.

Aim. To evaluate the effect of culprit coronary artery revascularization after 48 hours from the symptoms’ onset on the prognosis of patients with ST-elevation myocardial infarction (STEMI).Material and methods. Of the 1172 patients admitted to City Clinical Hospital № 13 in 2018 due to STEMI, 43 patients (4%) were included in the retrospective study. There were following inclusion criteria: hospitalization after 48 hours from the symptoms’ onset, no clinical signs of myocardial ischemia, and complete coronary artery occlusion according to angiography. The mean age of the subjects was 61,3±10,6 years, 34 (79%) men and 9 (21%) women. The subjects were divided into two groups: group 1 (n=22) — management with percutaneous coronary intervention (PCI), group 2 (n=21) — management with medications. The groups differ only in the severity of coronary atherosclerosis according to SYNTAX score: group 1 — 14,0 [11.0; 19.5], group 2 — 26,0 [16,5; 31,0] (p=0,009). At the end of inpatient treatment, patients underwent echocardiography. Death and myocardial infarction were monitored during hospitalization and for 12 months after discharge.Results. During hospitalization, 2 patients died (4,7%; one in each group, p=1,00). No recurrent MI were reported. The left ventricular ejection fraction in the PCI group was 50 [46; 54] %, in the group with drug therapy — 43 [38; 50] % (p=0,01). Out of 43 included patients, long-term outcomes were followed up in 32 (74%). Among them, 1 (5,8%) patient died in group 1, 6 (33,3%) patients — in group 2 (p=0,04). In total, death or recurrent MI in the first group was observed in 2 (12%) patients, in the second group — in 5 (33%) patients (p=0,14).Conclusion. Revascularization of a fully occluded culprit coronary artery in stable patients with STEMI after 48 hours of symptoms’ onset is associated with a higher inhospital left ventricular ejection fraction and a decrease in 12-month mortality.

Aim. To study the mechanisms, features of clinical manifestations and predicting of cardiotoxicity resulting from anthracycline chemotherapy.Material and methods. We examined 176 women with breast cancer who received anthracycline antibiotics as part of polychemotherapeutic (PCT) treatment. Patients were divided into 2 groups: with the development of cardiotoxic remodeling — group 1 (n=52) and with preserved heart function — group 2 (n=124). We conducted echocardiographic (EchoCG) tests before the start, during and after anthracycline chemotherapy. In the serum after the termination of PCT treatment, the concentrations of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and soluble Fas ligand (sFas-L) were determined.Results. Analysis of EchoCG parameters in patients after 12 months of PCT finish, showed a significant difference in the final systolic and end diastolic sizes, as well as a significant decrease in the left ventricular ejection fraction in group 1 compared with those before the start of treatment. A direct correlation was found between the end-systolic and end-diastolic volumes and inverse correlation between left ventricular ejection fraction and the resulting summary dose of doxorubicin. EchoCG changes in women of group 1 after the first course of PCT treatment were recorded in 49% of cases and 11% of cases — in group 2. The concentrations of sFas-L and NT-proBNP after PCT therapy finish in group 1 were significantly higher compared with group 2. Patients with significantly elevated NT-proBNP levels were had a high risk of heart disease developing during 12 months follow-up. A high concentration of NT-proBNP is a predictor of cardiovascular complications, which is more sensitive than EchoCG.Conclusion. Fas-associated apoptosis plays an important role in the pathogenesis of anthracycline cardiotoxicity. NT-proBNP may be an important biomarker for cardiotoxicity development, which already effective when EchoCG or clinical signs is absent.

Background: Heart failure (HF) and atrial fibrillation (AF) commonly coexist and patients with both diseases have a worse prognosis than those with HF or AF alone. The objective of our study was to identify the factors associated with one-year mortality in patients with HF and AF, depending on the left ventricular ejection fraction (LVEF). Methods: We included 727 patients with HF and AF consecutively admitted in a clinical emergency hospital between January 2018 and December 2019. The inclusion criteria were age of more than 18 years, diagnosis of chronic HF and AF (paroxysmal, persistent, permanent), and signed informed consent. The exclusion criteria were the absence of echocardiographic data, a suboptimal ultrasound view, and other cardiac rhythms than AF. The patients were divided into 3 groups: group 1 (337 patients with AF and HF with reduced ejection fraction (HFrEF)), group 2 (112 patients with AF and HF with mid-range ejection fraction (HFmrEF)), and group 3 (278 patients with AF and HF with preserved ejection fraction (HFpEF)). Results: The one-year mortality rates were 36.49% in group 1, 27.67% in group 2, and 27.69% in group 3. The factors that increased one-year mortality were chronic kidney disease (OR 2.35, 95% CI 1.45–3.83), coronary artery disease (OR 1.67, 95% CI 1.06–2.62), and diabetes (OR 1.66, 95% CI 1.05–2.67) in patients with HFrEF; and hypertension in patients with HFpEF (OR 2.45, 95% CI 1.36–4.39). Conclusions: One-year mortality in patients with HF and AF is influenced by different factors, depending on the LVEF.

Objectives: The aim of this study was to evaluate the relationship between valvular resistance and stroke volume (SV) and to assess SV adequacy to afterload in patients with severe aortic stenosis (AS) and normal left ventricular ejection fraction (LVEF). Methods: We assessed clinical characteristics and echocardiographic parameters in 44 patients with isolated severe AS and preserved LVEF. LV end-diastolic pressure (LVEDP) and LV mean diastolic pressure (LVMDP) were measured by cardiac catheterization. SV values were plotted in relation to valvular resistance. Patients were divided into 2 groups, with an SV that was higher (group 1) or lower (group 2) than the SV calculated by a regression equation using valvular resistance as the dependent variable. Results: At the same degree of valvular stenosis, the patients in group 1 exhibited better contractility as assessed by global longitudinal strain (p < 0.05), higher peak (p < 0.01) and mean gradient (p < 0.05), indexed SV (p < 0.001) and transvalvular flow (p = 0.01) than the patients in group 2, who had a higher heart rate (HR, p < 0.05), shorter ejection time (ET, p < 0.05) and more elevated LVEDP (p < 0.05) and LVMDP (p < 0.05). Conclusion: The presence of inappropriately decreased SV relative to afterload in patients with severe AS and normal LVEF was associated with lower contractility, higher HR, shorter ET and elevated LV diastolic pressure, which suggest failed hemodynamic adaptation to afterload.

treatment decisions for percutaneous coronary intervention (PCI) and/or coronary artery bypass graft (CABG) in patients with complex coronary artery disease (CAD) and/or unprotected left main stem disease (ULMSD).Objectives: To assess the agreement between the clinical decisions of the cardiologist and the SS II recommendation regarding the revascularization strategies in patients with complex CAD and/or ULMSD.Patients and Methods: Prospective data from patients who presented to Baghdad Medical City Catheterization Labs for coronary angiography and were followed up between January 2014 and November 2015 were analyzed. For these patients, SS II was assessed by the two anatomical variables (SS and presence of ULMSD) and six clinical variables (age, creatinine clearance, left ventricular ejection fraction, sex, chronic obstructive pulmonary disease, and peripheral vascular disease) to predict 4-year mortality after revascularization with PCI and/or CABG. These scores were then compared with the clinical decisions of cardiologists. After 1 year of data collection, we followed up the patients by phone to assess their mortality status. Patients were categorized into three groups according the interventional procedures: Group 1 (for PCI), Group 2 (for CABG), and Group 3 (for PCI vs. CABG).Results: Two hundred patients were enrolled. Their mean age was 60.23 ± 9.836 years, and 157 (78.5%) were men. Depending on the clinical judgment of the cardiologist, 71 (35.5%) patients were referred for PCI (Group 1), 119 (59.5%) patients for CABG (Group 2), and the remaining 10 (5%) patients for PCI vs. CABG (Group 3). Based on an assessment of 4-year mortality by the SS II, CABG would have been the treatment of choice in 67 (33.5%) patients, PCI in 30 (15%) patients, and both the treatments in 103 (51.5%) patients. There was a concordance between the clinical decision of the cardiologist and SS II in 67 (33.5%) patients and discordance in 133 (66.5%) patients. Six patients died within 1 year, most of whom were from the discordant group.Conclusion: There was a statistically significant discordance between the SS II recommendation and clinical judgment of the interventional cardiologist. SS II proved to be a useful objective tool to assist experienced clinical judgment in determining appropriate revascularization strategy for CAD patients. المقدمة:درجة السنتاكس ٢ تعد طريقة ارشادية لاختيار طريقة العلاج في المرضى اللذين يعانون من امراض شرايين القلب التاجية المعقدة مع او بدون امراض الشريان الايسر الرئيسي غير المحمي. الهدف: لتقييم نسبة عدم التوافق بين القرار السريري لاختصاصي القلبية وتوصيات درجة السنتاكس ٢ بالنسبة لخطة العلاج في المرضى المصابين بآمراض شرايين القلب التاجية المعقدة مع او بدون امراض الشريان الايسر الرئيسي غير المحمي.                        طرائق البحث: يتم جمع معلومات المرضى اللذين يخضعون لاجراء القسطرة التشخيصية لشرايين القلب في صالات القسطرة في مدينة الطب وتتم متابعة المرضى ايضا وتكون مدة الدراسة للفترة من شهر كانون الثاني لسنة ٢٠١٤م الى شهر تشرين الثاني لسنة ٢٠١٥م وخلال هذه الفترة يتم تقييم المرضى عن طريق درجة السنتاكس ٢ وست متغيرات سريرية للتنبؤ بآحتمالية حدوث الوفاة خلال الاربع سنوات بعد عودة التوعي ومقارنتها مع القرار السريري لاختصاصي القلبية. ثم بعد مرور سنة على جمع الداتا، نقوم بمتابعة حالة المرضى عن طريق الاتصال الهاتفي لمعرفة إذا حدثت حالات الوفاة. يتم تقسيم المرضى الى ٣ مجاميع، المجموعة الاولى والتي تخضع للتداخل القسطاري، المجموعة الثانية والتي تخضع لعملية جراحية لزرع شرايين القلب، والمجموعة الثالثة والتي لديها احتمالية للخضوع للقسطرة او للعملية الجراحية.     النتائج: تم اشراك مئتا مريض في الدراسة، معدل العمر ٦٠.٢٣ ± ٩.٨٣٦سنة، ١٥٧ (٧٨.٥٪) من المرضى ذكور. بالاعتماد على القرار السريري لاختصاصي القلبية تم تحديد ٧١ (٣٥.٥٪) من المرضى للخضوع للتداخل القسطاري (المجموعة الاولى)، ١١٩ (٥٩.٥٪) من المرضى تم ارسالهم لاجراء عملية جراحية (المجموعة الثانية) وبقية المرضى ١٠ (٥٪) تم ادراجهم تحت احتمالية خضوعهم للتداخل القسطاري او العملية الجراحية. بالنسبة لتققيم حالة الوفاة للاربع سنوات بالاعتماد على درجة السنتاكس ٢، كانت النتيجة ان العلاج المفضل هو العمليات الجراحية وبنسبة ٣٣.٥٪، في حين ان نسبة المرضى الخاضعين للتداخل القسطاري كانت ١٥٪، وكانت النسبة متوازية بالنسبة للمرضى الخاضعين للعمليات الجراحية او التداخل القسطاري ٥١.٥٪. كان هنالك توافق بين القرار السريري لاختصاصي القلبية ودرجة السنتاكس ٢ وبنسبة ٣٣.٥٪، في حين ان نسبة عدم التوافق للمرضى كانت ٦٦.٥٪. خلال سنة واحدة توفي ستة مرضى ومعضمهم كانوا من مجموعة عدم التوافق.                  الاستنتاج: هذه الدراسة اظهرت عدم توافق هام بين توصيات درجة السنتاكس ٢ والقرار السريري لاختصاصي القلبية.

Background: According to guidelines, implantable cardioverter defibrillator (ICD) is recommended in prevention of sudden cardiac death (SCD) in heart failure (HF) patients (pts). Guidelines have several limitations because ICD indication is based mainly on left ventricular ejection fraction (EF). Recent data showed that, independently from EF, 123-iodine metaiodobenzylguanidine imaging (123-I MIBG) could help to identify HF pts at high risk of SCD [heart/ mediastinum (H/M) ratio ≤1.6 and a summed score (SS) > 26], who may benefit of ICD. Aim: Our aim is to assess, in a real world registry, the role of 123-I MIBG for the prediction of ventricular tachyarrhythmia (VT) causing appropriate ICD therapy in HF pts. Methods: We consecutively enrolled 97 patients admitted to our hospital with diagnosis of HF, left ventricular ejection fraction (LVEF) ≤35% and indication to ICD. All patients underwent MIBG imaging. The patients were classified into two groups: Group 1 with H/M≤1.6 , SS> 26; Group2 with H/M>1.6, SS <26. All patients underwent 1 year follow-up. Results: 65 pts were included in group 1 and 32 pts in group 2. All baseline characteristics were similar in 2 groups apart from the etiology (table 1). In group 1, H/M ratio was 1.37±0.3 vs 1.8 ± 0.2 in group 2 (p=0.0002); SS was 37.5± 9.7 vs 16 ±6 in group 2 (p = 0.0001). At 1 year follow-up VTs causing appropriate ICD therapy in group 1 were 13.4% vs 1.28% in group 2(p=0.02); overall cardiac events were in group 1 16.4 % vs 1.92% in group 2 (p=0.02). Conclusion: Our results suggest that 123 I-MIBG can identify patients at increased risk for arrhythmic death and can be useful in the decision-making of ICD implantation independently from ejection fraction.

Abstract Background Myocardial infarction with nonobstructive coronary arteries (MINOCA) constitutes about 10% of the cases of acute coronary syndromes (ACS). It is a working diagnosis and requires further diagnostics to determine the cause of ACS. Methods In this study, 178 patients were initially diagnosed with MINOCA over a period of 3 years at the Department of Invasive Cardiology of the University Clinical Hospital in Białystok. The value of estimated glomerular filtration rate (eGFR) was calculated for all patients. The patients were divided into 2 groups depending on the value of eGFR: group 1—53 patients with impaired kidney function (eGFR < 60 mL/min/1.73 m2; 29.8%) and group 2—125 patients with normal kidney function (eGFR ≥ 60 mL/min/1.73 m2; 70.2%). Results In group 1, the mean age of patients was significantly higher than that of group 2 patients (77.40 vs 59.27; p < 0.0001). Group had more women than group 2 (73.58% vs 49.60%; p = 0.003). Group 1 patients had higher incidence rate of arterial hypertension (92.45% vs 60.80%; p < 0.0001) and diabetes (32.08% vs 9.60%; p = 0.0002) and smoked cigarettes (22.64% vs 40.80%; p = 0.020). Group 1 patients had higher incidence rate of pulmonary edema, cardiogenic shock, sudden cardiac arrest (13.21% vs 4.00%; p = 0.025), and pneumonia (22.64% vs 6.40%; p = 0.001). After the 37-month observation, the mortality rate of the patients with MINOCA was 16.85%. Among group two patients, more of them became deceased during hospitalization (7.55% vs 0.80%; p = 0.012), followed by after 1 year (26.42% vs 7.20%; p = 0.0004) and after 3 years (33.96% vs 9.6%; p < 0.0001). Multivariate analysis revealed that the factors increasing the risk of death in MINOCA are as follows: older age, low eGFR, higher creatinine concentration, low left ventricular ejection fraction, and ST elevation in ECG. Conclusion Impaired kidney function is diagnosed in every third patient with MINOCA. Early and late prognosis of patents with MINOCA and renal dysfunction is poor, and their 3-year mortality is comparable to patients with myocardial infarction with significant stenosis of the coronary arteries and impaired kidney function.
