Age and Left Ventricular Impairment Predict Reopening for Bleeding

Statistical analysis of data collected prospectively from all patients undergoing surgery under cardiopulmonary bypass from September 1994 to November 1998 (group 1) was performed to identify preoperative risk factors for reopening for bleeding. Multiple logistic regression analysis of 19 preoperative variables was carried out with reoperation for bleeding as the endpoint. The protocol for intraoperative use of aprotinin was then changed to include high-risk patients. Data collected from all subsequent patients from May 1999 to March 2002 (group 2) were analyzed. Subgroup analyses on primary isolated coronary artery surgery were also performed. Data were obtained from 1,946 patients aged 22 to 88 years (mean, 62.5 years). Older age, severe left ventricular impairment, redo surgery, and chronic renal failure were the independent predictors of reopening for bleeding in group 1. There were no independent predictors of reopening in group 2. Older age and chronic renal failure were the predictors of reexploration for bleeding in patients undergoing primary isolated coronary artery grafting. Prophylactic measures to prevent excessive bleeding should be used in elderly patients and those with severe left ventricular impairment, redo surgery, and chronic renal failure.

Objectives There is an increased calcium phosphate product level causing the formation of calcification in the arterial wall and thus decreased quality of fistula in patients with chronic renal failure. The purpose of our study is to verify the relationship between arteriovenous fistula re-operation and high calcium phosphate product level. Methods Seventy-nine consecutive patients with chronic renal failure between April 2016 and February 2018 were included in the study. Patients having calcium phosphate product level ≥50 mg2/dl2 were defined as group 1, whereas those having <50 mg2/dl2 were defined as group 2. Primary outcome of interest was the need for re-operation during the follow-up and to determine the risk factors for re-operation. To determine independent predictors for re-operation, multivariate logistic regression model was used. Results The rates of redo and tredo operation were significantly higher in group 1 compared to group 2 ( p = 0.01 and 0.04). In multivariate analysis, phosphate (OR: 1.84, 95% CI: 1.00–3.40, p = 0.05) and triglyceride (OR: 1.01, 95% CI: 1.00–1.02, p = 0.04) levels for redo operation and calcium phosphate product level (OR: 1.11, 95% CI: 1.01–1.22, p = 0.03) for tredo operation were found to be independent predictors. Conclusions High calcium phosphate product level leads to increased risk of arteriovenous fistula re-operation by causing arterial stiffness in this patient group. Additionally, these re-operations place additional burden on morbidity and cost efficacy. Thus, we recommend keeping the calcium phosphate product level at the optimal level in these patients to avoid both the risk of arteriovenous fistula re-operation and the other cardiovascular problems.

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 >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.

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.

Low affinity platelet factor 4 (LA-PF4) is a specific platelet secretory protein immunologically related to β-thromboglobulin and to platelet basic protein that stimulates cell growth. The level of LA-PF4 antigen was determined by specific radioimmunoassay in platelet poor plasma (PPP) and platelet rich plasma (PRP) of 17 normal individuals (NI), 9 patients on hemodialysis (HD) and 18 patients with chronic renal failure (CRF) who were not dialysed. Eight patients with glomerular filtration rate (GFR) 5-20 ml/min were included to group 1 and 10 patients with GFR 30-50 ml/min were included to group 2. Levels of LA-PF4 in ng/ml PPP were 31.9 ± 2.8 in NI, 291.8 ± 26.3 in HD, 149.4 ± 45.2 in group 1 of CRF and 103.7 ± 11.1 in group 2 of CRF. Differences between patients and NI were significant at P <0.05. After 3 hours of hemodialysis LA-PF4 increased to 505.0 ± 92.3 (P < 0.05), however, there was no changes in PPP level across the artifical kidney at one hour. The levels of LA-PF4 in PRP of patients with CRF and HD did not differ from NI. Mean LA-PF4 excretion in urine (ng/day/100mg creatinine) was 57.7 ± 6.4 (range 33.3-75.7) in 6 NI with GFR >60 ml/min and 1461.5 ± 674.6 (range 105.3-7041.6) in 10 CRF patients. In conclusion, elevation of LA-PF4 in PPP of patients with CRF and its increased urinary excretion suggest stimulation of platelet secretion and/or decreased metabolism of LA-PF4 in the kidney.

Abstract Purpose Basing on semiquantitative assessment of 99mTc-MIBI uptake in parathyroids of secondary hyperparathyroidism (SHPT) patients from chronic renal failure, objective guidance could be given to improve the qualitative diagnosis accuracy of MIBI uptake.Methods MIBI uptake intensiveness was semiquantitatively calculated with software ImageJ. MIBI uptake intensiveness and clinical indices were compared in 3-level grouping method consisting of slight (group 1), medium (group 2) and high (group 3) MIBI uptake groups and 2-level grouping method consisting of insignificant and significant MIBI uptake groups.Results Patient age, renal failure course, hemodialysis vintage, glomerular filtration rate (GFR), serum parathyroid hormone (PTH) and alkaline phosphatase (AKP) were positively, but serum uric acid (UA) was negatively, significantly related to MIBI uptake intensiveness; patient age was negatively, but serum phosphorus (P) and calcium (Ca) ´ P were positively, significantly related to MIBI washout; oral administration of calcitriol and calcium would significantly reduce MIBI uptake and washout. MIBI uptake tendency might alter during specified course. In 3-level grouping method, such 7 indices as the MIBI uptake intensiveness, renal failure course, hemodialysis vintage, serum AKP, Ca, cysteine proteinase inhibitor C and PTH were comparable between group 1 and 2, but were significantly different between group 1 and 3, and between group 2 and 3. In 2-level grouping method, above 7 indices plus blood urine nitrogen (BUN)/Creatinine were all significantly different between insignificant and significant group with these indices except BUN/Creatinine being greater in significant group than in insignificant group. All above significant relations or differences were with p < 0.05.Conclusions Patient age, renal failure course, hemodialysis vintage, GFR, serum PTH, AKP, UA, phosphorus and Ca ´ P, oral administration of calcitriol and calcium, and parathyroids themselves could significantly influence MIBI uptake in parathyroids of SHPT patients. 2-level grouping method should be adopted to qualitatively diagnosis MIBI uptake.

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.

Introduction: 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)Methods: 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 >90. The CFR measurements were carried out through a second harmonic transthoracic Doppler echocardiography.Results: 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 < .05). After bypass surgery, there was a significant increase in the mean postopera-tive CFR, when compared with the mean preoperative CFR (P = .001).Conclusion: 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.

Abstract Background Despite wide utility of global longitudinal strain in the assessment of left ventricular function up to now little is known about layer specific quantification of myocardial function during stress tests and its potential for ischemia detection. Purpose To investigate diagnostic utility of layer specific LS during stress echocardiography using marker segments in patients with established Left Anterior Descending (LAD) coronary artery status. Methods We retrospectively analyzed 63 patients (mean age 62.5±9.9 years, 62% males) with suspected coronary artery disease, who had performed dobutamine stress echocardiography (DSE). Layer specific speckle tracking LS analyses were performed during rest, maximal stress and recovery. As a marker for LAD (segment most probably supplied by this artery) we used mid-anterior left ventricle segments. LAD status were established with coronary angiography or angioCT and consider as significant if ≥70% stenosis was present. Results In our study group 14 patients had significantly stenosed LAD (group 1) and 24 had normal coronaries (group 2). We detected significantly lowered absolute values of strain in endocardial and mid-myocardial layers of segments supplied by stenosed LAD at rest for endocardium −8.6% (group 1) vs −13.4% (group 2); p=0.045; and mid-myocardium −7.3% (group 1) vs −11.2% (group 2); p=0.044. Moreover, we observed similar trend at recovery, however without reaching statistical significance. Conclusions Longitudinal strain analysis focused on segments supplied by assessed coronary artery my provide quantitative data confirming ischemia in the settings of rest and stress echocardiography. Our pilot study suggest that for inotropic agents like dobutamine the potential ischemic dysfunction may be however masked at peak stage of the test.

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.
