Introduction/Aim. Atherosclerosis presents a serial of highly specific cellular and molecular responses, and could be described as inflammatory diseases. Accordingly, for development of acute myocardial infarction (AMI), structure and vulnerability of atherosclerotic plaque are more important than the extent of stenosis of infarct-related artery. Consequently, inflammation and atherosclerosis and its complications are in good correlation. C-reactive protein (CRP) as nonspecific inflammatory marker, has prognostic significance in coronary artery diseases. The aim of this study was to establish the correlation between inflammatory response expressed as levels of CRP and fibrinogen in serum and extent of coronary artery stenosis. Methods. Study included 35 patients with acute myocardial infarction, as the first manifestation of coronary artery disease, which were treated with thrombolytic therapy according to the guidelines. All the patient had a reperfusion. The patients with acute or chronic inflammatory diseases, an increased value of sedimentation, fibrinogen, CK ?190 U/L, early and late complications of AMI were excluded. CRP was measured on admission, after 24, 48 and 72 hrs, and 21 days latter, while fibriogen only on admission. Results. All the patients underwent coronary angiography, and were divided into two groups: the group 1 (23 patients), with significant stenosis of infarct-related artery (stenosis ? 75%), and the group 2 (13 patients) without significant stenosis (< 75%). Mean value of CRP serum level on admission in the group 1 was 4.4 mg/L, and in the group 2 7.2 mg/L (p < 0.001). The mean value of fibrinogen on admission in the group 1 was 2.7 g/L, and in the group 2 3.0 g/L (p < 0.001). The mean CRP value after 48 hrs in the group 1 was 21.7 mg/L, and in the group 2 42.4 mg/L. (p < 0.001). After three weeks, the mean CRP value was 4 mg/L in the group 1 and 5.5 mg/L in the group 2 (p < 0.001). There was no significant difference between the groups 1 and 2 related to gender, age, localization of AMI, CK, EF value, and risk factors for coronary artery disease. Conclusion. The patients with nonsignificant stenosis of infarct-related artery had increased inflammtory responses according to the CRP value, as a result of inflammatory process in atherosclerotic plaque and/or enhanced individual reactivity.

Many parameters included in the Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) and CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke, vascular disease, age 65-74 years, sex category) scores also predict coronary artery disease (CAD). We modified the ATRIA score (ATRIA-HSV) by adding hyperlipidemia, smoking, and vascular disease and also male sex instead of female. We evaluated whether the CHA2DS2-VASc, CHA2DS2-VASc-HS, ATRIA, and ATRIA-HSV scores predict severe CAD. Consecutive patients with coronary angiography were prospectively included. A ≥50% stenosis in ≥1epicardial coronary artery (CA) was defined as severe CAD. Patient with normal CA (n = 210) were defined as group 1, with <50% CA stenosis (n = 178) as group 2, and with ≥50% stenosis (n = 297) as group 3. The mean ATRIA, ATRIA-HSV, CHA2DS2-VASc, and CHA2DS2VASc-HS scores increased from group 1 to group 3. A correlation was found between the Synergy between PCI with Taxus and Cardiac Surgery score and ATRIA ( r = 0.570), ATRIA-HSV ( r = 0.614), CHA2DS2-VASc ( r = 0.428), and CHA2DS2-VASc-HS ( r = 0.500) scores ( Ps < .005). Pairwise comparisons of receiver operating characteristics curves showed that ATRIA-HSV (>3 area under curve [AUC]: 0.874) and ATRIA (>3, AUC: 0.854) have a better performance than CHA2DS2-VASc (>1, AUC: 0.746) and CHA2DS2-VASc-HS (>2, AUC: 0.769). In conclusion, the ATRIA and ATRIA-HSV scores are simple and may be useful to predict severe CAD.

<p><strong>Introduction</strong>: There are only a limited number of studies on the link between mild renal failure and coronary artery disease. The purpose of this study is to investigate the effects of mild renal failure on the distal vascular bed by measuring the coronary flow reserve (CFR) in transthoracic echocar-diography after coronary artery bypass grafting (CABG)</p><p><strong>Methods</strong>: The study included 52 consecutive patients (12 women and 40 men) who had undergone uncomplicated CABG. The patients were divided into 2 groups. Group 1 included patients with a preoperative glomerular filtra-tion rate (GFR) of 60-90 (mild renal failure), and group 2 included those with a GFR &gt;90. The CFR measurements were carried out through a second harmonic transthoracic Doppler echocardiography.</p><p><strong>Results</strong>: The mean age was 60.08 ± 1.56 years in group 1 and 60.33 ± 1.19 in group 2. The mean preoperative CFR was 1.79 ± 0.06 in group 1 and 2.05 ± 0.09 in group 2. The mean postoperative CFR was 2.09 ± 0.08 in group 1 and 2.37 ± 0.06 in group 2. There was a statistically significant difference between the 2 groups as to preoperative creatinine clearance, preopera-tive estimated GFR, postoperative day 7 creatinine clearance, postoperative month 6 creatinine clearance, postoperative day 7 estimated GFR, postoperative month 6 estimated GFR, pre-operative CFR, and postoperative CFR (P &lt; .05). After bypass surgery, there was a significant increase in the mean postopera-tive CFR, when compared with the mean preoperative CFR (P = .001).</p><p><strong>Conclusion</strong>: In our study, we detected a decrease in CFR in patients with mild renal failure. We believe that in patients undergoing CABG for coronary artery disease, mild renal failure can produce adverse effects due to deterioration of the microvascular bed.</p>

Aim. To compare the immediate outcomes of combined coronary artery bypass grafting (CABG) with coronary endarterectomy (CE) and isolated CABG.Material and methods. This retrospective study included 192 patients with stable angina who underwent myocardial revascularization in the period from January 2016 to August 2018. The patients were divided into 2 groups. Group 1 included patients who underwent combined CABG and CE, while group 2 — patients who underwent isolated CABG. Patients in both groups did not differ in the main preoperative characteristics, with the exception of the incidence of obesity and right coronary artery disease.Results. In-hospital mortality in group 1 was 2,2% (n=2), in group 2 — 2% (n=2). The incidence of perioperative myocardial infarction in group 1 was 1% (n=1) and in group 2 — 0%. There were no significant differences between groups in the following postoperative parameters: in-hospital mortality, perioperative myocardial infarction, need and duration of inotropic support, duration of mechanical ventilation (MV) and need for long-term mechanical ventilation, stroke, arrhythmias, resternotomy for bleeding. In group 1, encephalopathy (11,8%) and respiratory failure (12,9%) were significantly more common.Conclusion. Combined CABG and CE is a safe technique for achieving complete myocardial revascularization in diffuse coronary artery disease, since, in comparison with isolated CABG, there is no increase in the incidence of death and perioperative myocardial infarction. However, in this category of patients, an increase in the incidence of non-lethal, non-disabling cerebral and pulmonary complications should be expected.

Aim: to compare the antianginal and pulse slowing effects, the impact on the ectopic myocardial activity as well as the safety of the treatment with beta - adrenoblocker bisoprolol, calcium antagonist verapamil and the combination of bisoprolol with amlodipine in patients with stable angina (SA) and bronchial asthma (BA). Materials and methods. The study included 90 patients with SA II-III functional class (FC) having concomitant persistent asthma of moderate severity, controlled, without exacerbation. The patients were divided into three groups with 30 individuals in each one depending on the main antianginal drug prescribed. Group 1 patients received a cardio - selective beta - adrenergic blocker bisoprolol (Concor) at the dose of 5 mg/day, patients of group 2 were treated by a calcium antagonist verapamil at the dose of 240 mg/day, patients of group 3 received combined therapy with bisoprolol at the dose of 5 mg/day and amlodipine at the dose of 5 mg/day given as a fixed combination (Concor AM 5/5). All the patients were investigated by the methods of daily ECG monitoring and respiratory function study (RFS) in addition to physical examination at baseline and after 4 weeks of treatment. Results. After 4 weeks of treatment, patients of group 1 and group 3 did not complain of angina attacks and did not use nitroglycerin unlike patients of group 2. The achieved heart rate (HR) in group 1 patients was 68.6±8.5 beats/min, in group 2 - 74.3±5.6 beats/min, in group 3 - 67.3±4.8 beats/min. A significant decrease in the number of supraventricular and ventricular extrasystoles occurred in patients of group 1 and group 3 only. Thus, the pulse slowing, antianginal, antiischemic and antiarrhythmic effect of the calcium antagonist verapamil, even at the dose of 240 mg/day, is not always sufficient for the patients with SA II-III FC and concomitant BA, unlike therapy with the inclusion of beta - blocker bisoprolol. During the study there was no registered deterioration in the indices of bronchial patency according to the RFS data in the patients of all three groups. Conclusion. In patients with coronary artery disease and concomitant asthma, all three types of pulse slowing therapy do not have any negative effects on bronchial patency. Therapy with the inclusion of beta - blockers (bisoprolol or its combination with amlodipine), in contrast to verapamil, reliably reduces heart rate and the number of supraventricular and ventricular extrasystoles in addition to a good antianginal effect.

The risk of cardiovascular complications is increased in patients with obstructive sleep apnea (OSA). Continuous positive airway pressure (CPAP) is the most effective way to treat clinically significant OSA. We hypothesized that the concentrations of the cardiac risk markers N-terminal brain natriuretic peptide (NT-proBNP) and high-sensitive troponin T (hs-TropT) correlate with the effectiveness of CPAP therapy in patients with OSA and coexisting coronary artery disease (CAD). Twenty-one patients with severe OSA and coexisting CAD (group 1) and 20 control patients with severe OSA alone (group 2) were treated with CPAP and monitored by laboratory-based polysomnography. NT-proBNP and hs-TropT levels were measured before and after CPAP. Apnea-hypopnea index (AHI) and oxygen desaturation were similar in both groups. In group 1, hs-TropT levels correlated with AHI and oxygen desaturation upon CPAP. Elevated NT-proBNP levels in group 1 were significantly reduced by CPAP. NT-proBNP levels correlated with AHI and showed negative correlation with ST-segment depression. No such correlations were found in group 2. CPAP has the potential to normalize elevated NT-proBNP serum levels in patients with severe OSA and coexisting CAD. Levels of NT-proBNP and hs-TropT correlated with AHI and oxygen desaturation.

Abstract Funding Acknowledgements PlaqueImage Background The relationship between the degree of pulmonary hypertension (PH) and left ventricular performance in patients with systemic sclerosis is still a controversial issue in the literature. We aimed to conduct a comparative analysis of indexes characterizing left ventricular systolic and diastolic function, in two etiological types of pulmonary hypertension involving different pathophysiological mechanisms: PH caused by systemic sclerosis and PH caused by myocardial ischemia. Material and method We performed a prospective study on 83 patients (36 patients with documented PAH with a systolic pulmonary arterial pressure – sPAP of &gt;35 mmHg and 47 subjects with normal sPAP), out of which group 1 – with systemic sclerosis (n = 48); group 2 – significant coronary artery disease - CAD (n = 35). Patients of each group were divided in two subgroups based on the diagnosis of PH: group 1A - subjects with scleroderma and associated PH (n = 20), group 1B - subjects with scleroderma without PH (n = 28), group 2A - ischemic patients with associated PH (n = 16) and subgroup 2B - patients with ischemic disease without PH (n = 19). Results Patients in group 1 presented a significantly higher number of female subjects (p = 0.001) and a higher mean age (p = 0.009) compared to group 2. Patients with associated PH presented a significantly lower left ventricular ejection fraction (LVEF) compared to those without PH within the ischemic group (p = 0.023). There was a significant inverse correlation between the sPAP and LVEF in ischemic patients (r=-0.52, p = 0.001) as well as for scleroderma patients without PH (r=-0.51, p = 0.04). Tissue Doppler analysis of the left ventricular function indicated a significant negative correlation between the septal E’ value versus the sPAP and lateral E’ value versus the sPAP (r=-0.49, p = 0.002; r=-0.43, p = 0,008). Conclusions Intrinsic myocardial damage plays an important role in left ventricular systolic function even in the absence of PAH. Scleroderma patients present a less pronounced deterioration of the LVEF in response to pulmonary hypertension, indicating that in this group, additional compensatory mechanisms could be involved in the complex response of myocardium to elevated pulmonary pressures.

Abstract Aims Women with evidence of ischaemia but no obstructive coronary artery disease (INOCA) often have coronary microvascular dysfunction (CMD). Although invasively measured coronary flow reserve (CFR) is useful for the diagnosis of CMD, intermediate CFR values are often found of uncertain significance. We investigated myocardial flow reserve and left ventricular (LV) structural and functional remodelling in women with suspected INOCA and intermediate CFR. Methods and results Women’s Ischemia Syndrome Evaluation-Coronary Vascular Dysfunction (WISE-CVD) study participants who had invasively measured intermediate CFR of 2.0≤ CFR ≤3.0 (n = 125) were included for this analysis. LV strain, peak filling rate (PFR) and myocardial perfusion reserve index (MPRI) were obtained by cardiac magnetic resonance imaging. Participants were divided: (i) Group 1 (n = 66) high MPRI ≥ 1.8, and (ii) Group 2 (n = 59) low MPRI < 1.8. The mean age was 54 ± 12 years and CFR was 2.46 ± 0.27. MPRI was significantly different but CFR did not differ between groups. LV relative wall thickness (RWT) trended higher in Group 2 and circumferential peak systolic strain and early diastolic strain rate were lower (P = 0.039 and P = 0.035, respectively), despite a similar LV ejection fraction and LV mass. PFR was higher in Group 1 and LV RWT was negatively related to PFR (r = −0.296, P = 0.001). Conclusions In women with suspected INOCA and intermediate CFR, those with lower MPRI had a trend towards more adverse remodelling and impaired diastolic LV function compared with those with higher MPRI. CFR was similar between the two groups. These findings provide evidence that both coronary microvessel vasomotion and structural and functional myocardial remodelling contribute to CMD.

AbstractThe purpose of this study was to present the outcomes of treatment of cardiogenic shock (CS) complicating acute myocardial infarction (AMI) among patients hospitalized from 1999 through 2006. The study enrolled 1003 patients. Group 1 comprised 87 patients presenting with AMI complicated with CS, whereas Group 2 comprised 916 patients presenting with AMI without CS symptoms. Determination of invasive treatment was according to standard guidelines. The endpoint comprised death, stroke, and reocclusion/reinfarction. Follow-up was confined to the intra-hospital period. CS was observed more frequently in cases of ST-elevation MI (STEMI) and right ventricular MI. The transportation and door-to-needle time were shorter in Group 1. CS patients were characterized by a more severe coronary artery disease, higher maximal creatinine kinase levels, lower global ejection fractions, and increased incidence of atrioventricular conduction disorders. The efficacy of percutaneous coronary intervention (PCI) was 82.26% in Group 1 and 95.03% in Group 2. Death occurred in 33.3% of CS patients and in 3.6% of AMI patients (p<0.0001). Our study proved that in a short-term follow-up, PCI is a procedure of high efficacy in CS patients. The short-term follow-up precluded a conclusion of statistically significant benefits from the shortening of the transportation and door-to-needle time.

Abstract Background and aimsLeft ventricular hypertrophy (LVH) is prevalent in obese individuals. Besides, both of LVH and obesity is associated with subclinical LV dysfunction. However, little is known about the interplay between body fat and LVH in relation to all-cause death in patients with coronary artery disease (CAD).MethodsIn this retrospective cohort study, a total of 2243 patients with angiographically proven CAD were included. Body fat and LV mass were calculated using formulas. Higher body fat was defined as the percentage of body fat was greater than 75th percentile. LVH was defined according to guidelines’ definition. Patients were divided into four groups: group 1, lower body fat and no LVH; group 2, lower body fat and LVH; group 3, higher body fat and no LVH; group 4, higher body fat and LVH. Cox-proportional hazard models were used to observe the interaction effect of body fat and LVH on all-cause death.ResultsOver 2.2 years, there were 120 deaths. Patients with higher body fat and no LVH (group 3) had similar risk of death (adjusted HR 1.83, 95%CI 1.00-3.38, P = 0.054) compared to the reference group (group 1), while patients with lower body fat and LVH (group 2) had the highest risk (adjusted HR 2.15, 95%CI 1.26–3.64, P = 0.005) of death. The results were robust after different degree of adjustment.ConclusionCertain amount of BF was not associated with increased risk of all-cause death in patients with CAD, even seems protective in those concomitant with LVH.

Background: The pain and limitation of shoulder function can disrupt daily activities of patients for months to years. Adhesive capsulitis is considered a self-limiting disease but the duration remains uncertain. The brunt of the disease is focussed on the inflamed joint capsule. On this basis, use of corticosteroid injection is justified. However, injection method is not conclusive. Objectives: To compare clinical benefits of intra-articular injection alone versus combined intra-articular and subacromial injections in management of adhesive capsulitis. Methods: Fifty-nine patients with diagnostic criteria for adhesive capsulitis were included in the study from March 2019 to September 2020. Patients were divided into two groups; patients who underwent intra-articular (IA) injection alone (Group 1) and those who received both intra-articular and sub-acromial (IA+SA) injection (Group 2). The injections were landmark guided. Patients were followed up at three, six, and 12 weeks. Pain was recorded using visual analogue scale (VAS) and subjective function using Constant-Murley score. Results: Twenty-eight patients were included in Group 1 (IA) and 31 in Group 2 (IA+SA). Thirty-six patients were female (18 each in Group 1 and Group 2) and 23 patients were male (Group 1 = 13; Group 2 = 10). In the twelfth week, VAS score was reduced in both the groups. On comparing the mean value of Constant-Murley score between the two groups there is significant difference in value recorded at the sixth and twelfth week. Conclusion: The IA+SA injection provides significant reduction in pain and better function in the short term over the IA injection.
