Abstract Background ST resolution (STR) after AMI is a non-invasive indicator of IRA reperfusion. We investigated whether pre-angiography STR predicted spontaneous IRA reperfusion in STEMI patients. Method Patients with STEMI undergoing primary PCI were recruited. Standard 12-lead ECG tracings were recorded at first medical contact, immediately prior to arterial puncture and 60 min after PCI. STR was classified as total (≥70%; group I), partial (≥30 and < 70%; group II) or none (< 30%; group III). Patients were followed up for 1-year. Results The final analysis included 349 patients (n = 77, 160 and 112 for groups I, II and III, respectively). Compared with groups I/II, pre-procedural TIMI flow in group III was less frequently grades 2 or 3 (P < 0.001). Pre-PCI STR ≥70% was an independent predictor of pre-PCI TIMI-3 flow (OR: 2.8; P < 0.001). Pre-PCI STR < 30% was independently associated with pre-PCI TIMI flow 0–2 (OR: 3.1; P < 0.001). STR = 35.55% seems to be an optimal cut off for pre-procedural TIMI-3 flow prediction with sensitivity 0.943, specificity 0.456, Youden index 0.399, P = 0.027. STR prior to PCI was inversely correlated with 1-year combined CV events rate. STR > 70% may predict a better clinical outcome. Conclusions Assessment of STR could potentially be used to stratify risk in patients with STEMI before PCI.

BACKGROUND Pelvic floor training (PFT) is the gold standard for conservative treatment of male stress urinary incontinence. OBJECTIVE To evaluate patients´ perspective at risk of incontinence on PFT and application of digital technologies for PFT. METHODS Patients undergoing transurethral surgery of the prostate (group I), radical prostatectomy (group II) or treatment at a specialized incontinence outpatient clinic (group III) were surveyed anonymously. Chi-Square test and Kruskal-Wallis-analysis were used for statistical analysis. RESULTS 180 patients were included in the final analysis. In group I (n=35) no patient underwent PFT prior to transurethral surgery. 23.5% of patients in group II (n=51) and 95.7% of patients in group III (n=94) performed PFT. 11.4% in group I, 80.4% in group II and 91.5% in group III have been advised to perform PFT by their urologist. Regarding the information level on PFT, patients from group I (median 1, range 0-5) are less satisfied than patients from group II (median 3, 0-9) or group III (median 5, range 0-10, p<0.001). 88.6% of patients from group I are willing to perform PFT as preventive treatment or to avoid incontinence surgery, 100% from group II and 68.4% from group III (p<0.001). The likelihood to use digital PFT is higher in group I (median: 9, range 0-10) and II (median: 9, range 0-10) than in group III (median: 4, range 0-10, p<0.001). CONCLUSIONS Patients at risk of incontinence currently have limited access to PFT, although they are willing to perform PFT. Digital PFT is highly accepted by patients preoperatively and might be a valuable tool to increase PFT participation.

Acute Inferior Myocardial Infarction

Background: The patient with inferior wall AMI, site of culprit lesions is an important determinant of outcome. Patient with RV infarction have a poor prognosis whereas those with occlusion of LCX have a good prognosis. Early diagnosis and treatment substantially reduce cardiac events particularly in high-risk patients. V4R can be used as to locate the site of obstruction. Materials and methods: 81 patients with acute inferior myocardial infarction admitted to the coronary care unit (CCU) within 12 hours after the onset of chest pain who underwent coronary angiogram were included in the study. Standard 12-lead ECG with right precordial lead V4R was recorded. Patients were categorized into within 3 groups according to early changes of V4R-Group- I - ST-segment elevation > 1 mm and positive T- wave, Group-II- ST-segment iso-electric and positive T-wave, Group-III- ST-segment depression >1 mm and negative T -wave. Results: In group I patients, highest percentage of the patients had lesion in proximal RCA (97.2%); whereas in group II patients, highest percentage in the distal RCA (89.7%) followed by LCX (41.4%) and in group III patients, highest percentage also in LCX (100.0%) followed by LAD (56.3%). Based on analysis of sensitivity and specificity, it was revealed that in group I patients of ECG finding suggested 100.0% sensitivity, 97.8% specificity and 98.8% accuracy. In group II patients, 92.9% sensitivity, 94.3% specificity and 93.8% had accuracy. In case of group III patients, 93.8% sensitivity, 98.5% specificity and 97.5% accuracy. Conclusion: The configuration of the ST-T segment in lead V4R is a sensitive and specific tool to recognize the occluded vessel in acute inferior MI whether it is proximal RCA, distal RCA or LCX. Since it is an inexpensive method, it can be readily used to locate the site of occlusion in AMI - Inferior. Keywords: Coronary artery disease; Myocardial infarction;, Lead V4r.

Abstract Background The degree of congestion in patients hospitalized for acute decompensated heart failure (ADHF) is estimated using traditional non-invasive markers such as echo-derived inferior vena cava diameter (IVCD) and NT-proBNP levels. The deterioration of right ventricular (RV) function and its uncoupling to pulmonary circulation (Pc) represents a turning point in terms of prognosis and clinical outcome in patients affected by heart failure. However, how RV-to-Pc uncoupling correlates with markers of decompensation and congestion in ADHF patients has never been explored. Purpose To investigate, in a cohort of ADHF patients, the association between the degree of RV-to-Pc uncoupling, assessed by the ratio between tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (PASP), IVCD and right atrial pressure (RAP) estimated at echocardiography. Methods Fourty-six ADHF patients both with reduced and preserved EF (mean age 73.15±10.85 years, 60.8% males) admitted to the Cardiology Department were prospectively enrolled within 24–48 hours from admission. In the acute phase all patients underwent transthoracic echocardiography and laboratory blood tests. Patients were then stratified in tertiles according to TAPSE/PASP ratio (group I: <0.4 mm/mmHg; group II: 0.4 to 0.6 mm/mmHg and group III: >0.6 mm/mmHg) correlating the degree of RV-to-Pc with non-invasive markers of congestion such as NT-proBNP, IVC maximum diameter and RAP. Other echocardiographic parameters including left ventricular (LV) systolic function and LV filling pressures were considered. Results An exponential inverse relationship was found between NT-pro-BNP levels at admission with levels decreasing progressively with the increment of the ratio (Group I: 12828±10600 ng/l; Group II 5549±5383 ng/l; Group III 3695±3870 ng/l; p=0.004) (Figure 1a). An analogous correlation was observed when considering the IVC maximum diameter (Group I: 20.87±5.37 mm; Group II 18.08±4.35 mm; Group III 10.9±3.36 mm; p<0.001) (Figure 1b) and the RAP estimated at echocardiography (Group I: 12.875±5.25 mmHg; Group II 9.157±4.82 mmHg; Group III 4±1.61 mmHg; p<0.001) (Figure 1c). In addition, progressively increasing values of LVEF (Group I: 28±11.3%; Group II 42±17.3%; Group III 49±11.8%; p=0.001) were detected from the lowest to the highest TAPSE/PASP tertiles. No correlation was observed in the three groups for E/E' values at admission (Group I: 17.17±6.7; Group II 19.42±8.36; Group III 15.92±5.7; p=0.5). Figure 1 Conclusions In ADHF, the association between RV to Pc uncoupling, echo-derived measures of congestion and natriuretic peptide levels is here described for the first time. The extent of RV dysfunction in ADHF deserves attention and seems to represent a critical and quite underestimated key mechanism between congestion resolution and in-hospital worsening HF.

Rationale: The role of prehospital (PH) antithrombotic medications in STEMI is debated; real-world data are scarce. We used the FAST-MI 2010 data to assess TIMI flow before PCI, in relation to PH administration of antithrombotic medications and timing of coronary angiography. Methods and Results: FAST-MI is a nationwide French registry including consecutive AMI patients in 213 centers in November 2010. Of 2364 STEMI patients, 2035 had TIMI flow assessed pre-intervention (1458 primary PCI, 289 lysis, 288 no reperfusion therapy); 41% had TIMI flow 2/3. PH use of antithrombotics was: ASA 52%, clopidogrel 37%, prasugrel 7%, GP IIb-IIIa 4%; unfractionated heparin 24%, other anticoagulants 22%. Mean age, risk factors, medical history, GRACE score, location of infarct did not differ between patients with TIMI 2/3 vs 0/1 flow. IRA patency was higher with time from onset to call less than 120min (45% vs 35%, P<0.001), and time from ECG to angio over 120 min (48% vs 33%,P<0.001). In the whole population, % TIMI flow 2/3 was higher with PH lytics (78% vs 42%, P<0.001) and differed according to PH antithrombotic use: no antiplatelet 42%, ASA alone 39%, clopidogrel 53.5%, prasugrel 58%, GPIIb-IIIa 40%; no anticoagulant 43%, UFH 46%, other anticoagulants 55%. Lysis (OR 5.67, 3.67-8.77), and combination of dual antiplatelets and anticoagulants (OR 1.59, 1.20-2.12) were independent correlates of higher patency. In patients with primary PCI, individual medications were not significantly correlated with IRA patency. Combined dual antiplatelet and anticoagulants, however, was a significant correlate of higher TIMI2/3 flow (adjusted OR 1.43, 1.05-1.96), as were shorter duration from onset to call (OR 1.53, 1.13-2.08) and longer time from ECG to angio (OR upper tertile vs lower tertile 1.65, 1.14-2.37). ST-segment resolution, reinfarction, stent thrombosis and TIMI major bleeding did not differ according to PH antithrombotics. Conclusion: In the whole population of STEMI patients (including lytic-treated patients), as in patients with primary PCI, PH administration of combined antiplatelet and anticoagulants is associated with increased IRA patency. In contrast, none of the individual antithrombotic medications significantly improved IRA patency.

Asymptomatic Individuals

Hypertension is a cardiovascular (CV) disease with high risk for CV morbid events (ME) that benefits from anti-hypertensive therapy. Resting blood pressure (BP) >140/90 mmHg serves as the diagnostic criterion for hypertension, and management has been aimed at BP reduction. Progression of CV disease in the absence of elevated blood pressure identifies individuals who might benefit from CV-protective therapy but are not currently being recognized as in need of treatment. In 2017 asymptomatic individuals evaluated for early functional and structural CV abnormalities, 1534 not taking anti-hypertensive drugs were available to determine the relationship between office blood pressure and the severity of CV abnormalities, as defined by a 10-test non-invasive disease score (DS) of 0-20. Previous studies have documented the high predictive value of DS for future CVME. The population was 53% male, average age 50±11 years, BP 122/77mmHg, LDL cholesterol 129±38 mg/dL, HDL 52±17mg/dL, triglycerides 109 mg/dL. DS was adjusted by eliminating the score for BP, but 9-test DS was still directly related to BP: 2.3 in those (n=550) <120/80 mmHg (Group I), 3.2 in those 120-129/80-85 mmHg (n=600) (Group II), 4.1 in those 130-139/85-89 mmHg (n=236) (Group III), and 5.7 in those 140+/90+mmHg (n=148) (Group IV). Nonetheless, DS of >6 indicative of high risk was present in 10% of Group I, 20% of Group II and 30% of Group III. BP was largely overlapping in individuals with no CV disease (DS 0-2), early disease (DS 3-5) and advanced disease (DS 6+). Therefore, reliance on resting BP leaves many at-risk individuals undiagnosed and untreated for early CV disease likely to progress. The hypertensive state exists in the absence of elevated BP and should be recognized and treated to prevent CVME.

Background: The prognosis of patients with persistent occlusion of the infarct related artery (IRA), despite lytic therapy is poor. Early detection of successful reperfusion and IRA patency is of great importance in terms of prognosis and identification of candidates for rescue percutaneous coronary intervention (PCI). P wave dispersion (PWD), a new parameter measured before and after fibrinolytic therapy (FT) is supposed to predict successful reperfusion in patients with anterior acute myocardial infarction (AMI).Objectives:To examine the prediction of successful reperfusion and infarct related artery (IRA) patency by measuring P wave dispersion in 12-lead surface ECG.Method:132 patients were selected and divided into two groups on the basis of ST segment resolution (STR) after 120 minutes of thrombolysis. Group I: patients with STR >70%; Group II: patients with STR < 70%. All patients underwent coronary angiography (CAG). IRA patency was considered if TIMI flow grade was >2.Results: Mean age of the successfully thrombolysed group was 49.12±9.54 and mean age of failedthrombolysis group was 52.08±8.23 years. Though higher age was associated with failed thrombolysis and it was statistically insignificant (p=0.06). Patients with higher BMI showed no significant difference in thrombolysis. It was observed that diabetes mellitus and dyslipidemia were significantly higher in group II patients (p=0.04 and p=0.03, respectively). The mean level of PWD after 120 minutes of thrombolysis (PWD120) was statistically significant (p=0.001) between two groups. After multivariate regression analysis PWD120 was found to be the significant predictor of ST segment resolution as well as IRA patency (OR = 1.101; 95% CI = 1.012 – 1.240; p = 0.01).Conclusion: P wave dispersion (PWD) in patients receiving thrombolytic therapy can be a predictor of successful reperfusion and patent infarct related artery (IRA). PWD values, in combination with other reperfusion parameters, can contribute to the identification of rescue PCI candidates.Bangladesh Heart Journal 2017; 32(2) : 100-105

The Impact

Aims: Early infarct-related artery patency has been associated with improved outcomes in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention. However, it is unknown whether this relationship persists in contemporary practice with pre-hospital initiation of treatment, use of novel P2Y12 inhibitors and frequent use of drug-eluting stents. The purpose of the study was to determine the impact of early infarct-related artery patency on outcomes in the contemporary EUROMAX trial. Methods and results: A total of 2218 patients were enrolled. The current analysis was done on 1863 patients who underwent percutaneous coronary intervention and had infarct-related artery patency data. Thirty-day outcomes were compared according to infarct-related artery flow before percutaneous coronary intervention (Thrombolysis in Myocardial Infarction (TIMI) flow 0/1 vs. TIMI flow 2/3), and interaction with antithrombotic strategy was examined. A patent infarct-related artery (TIMI flow 2/3) was present in 707 patients (37.9%) and was associated with a higher rate of final TIMI 3 flow grade (98.9 vs. 92.6%; p<0.001). At 30 days, a patent infarct-related artery was associated with lower rates of cardiac death (1.3% vs. 2.9%; p=0.026) and the composite of death or myocardial infarction (2.7% vs. 4.6%; p=0.039). There were no interactions between antithrombotic treatment and the impact of infarct-related artery patency on cardiac death, myocardial infarction, or the composite of death or myocardial infarction (Breslow–Day interaction p-values of 0.21, 0.33 and 0.46, respectively). Conclusion: Despite evolution in primary percutaneous coronary intervention strategies, early infarct-related artery patency is still associated with higher procedural success and improved clinical outcomes. The choice of antithrombotic strategy did not interact with the benefits of a patent infarct-related artery at presentation.

Objectives: To determine Post streptokinase TIMI flow grade (rate) in infarctrelated artery (IRA) in ST elevated myocardial infarction patients. Study Design: A nonrandomizedprospective study. Period: Dec-2014 to Dec-2015. Setting: Sheikh Zayed MedicalCollege and Hospital Rahim Yaar Khan. Methods: 113 patients were selected to see poststreptokinase TIMI flow grade in infarct related artery (IRA). The data was analyzed using SPSSVersion 20. Descriptive statistics was used to see and analyze the data. Results: Mean ageof patients was 50.43±9.81 years. There was more males (87.61%) as compared to females(12.39%). After thrombolyzation with streptokinase 23.01% patients were with TIMI grade 0/1(failed perfusion), 45.13% (51) patients with TIMI grade 2 (partial perfusion) and 31.86% patientswith TIMI grade 3 (full perfusion) in infarct related artery. In our study TIMI flow improved tograde 2/3 (partial to complete perfusion) in 76.99% patients. There were 11.73% patients withTIMI 0/1 with 50% ST segment resolved, 8.85% patients with TIMI 0/1 with persisted 50% STsegment, 32.74% patients with TIMI 2 with 50% ST segment resolved, 11.5% (13) patients withTIMI 2 with 50% ST segment persisted, 32.74% patients with TIMI 3 with 50% ST segmentresolved and 4.42% patients with TIMI 3/1 with 50% ST segment persisted. Post streptokinasethere was no coronary artery thrombus in 91.07 % patients. While 6.25% patients had thrombusin left coronary artery and 2.84% patients had right coronary artery thrombus. Conclusion:Thrombolyzation with streptokinase improves perfusion in infarct related artery and increasesTIMI flow grade in STEMI patients. It reduces the risk of recurrent myocardial infarction byrestoration of blood flow in infarct related artery.

The aggressiveness of urothelial bladder cancers can be caused by reactions of stroma. Immunocompetent cells, which involved in antitumor response, are also able to stimulate tumor growth. Aim of the study: to study the features of immuncellular infiltration of non-invasive urothelial bladder cancers (NIUBC) to identify criteria for recurrence and progression prediction. Materials and methods: we formed three groups of studies, each of them contained 14 cases: NIUBC without recurrence — Group I, primary NIUBC with recurrence, but without progression — Group II, and primary NIUBC with recurrence and with progression — Group III. Immunohistochemistry was performed using primary monoclonal antibodies from DAKO to CD3, CD4, CD8, CD20 and CD68 cells. Statistical processing of research results was performed using the “Statistica 6.0” package. The relationship between parameters was studied by non-parametric Pearson χ-square test and Spearman test. A value of p<0.05 was considered statistically significant. Results: NIUBC I group was associated with weak stromal infiltration of immunocompetent cells: CD3 + lymphocytes (p<0.05), CD8 + T-killers (p<0.005) and CD68 + macrophages (p<0.005). In cancers of group III, immune cell infiltration was more observed than in cancers of groups I and II (p<0.001 and p<0.03) and was characterized by infiltration of CD3 + (p<0.01) and CD8 + cells (p<0.03). Thus, differentiation and recurrence of NIUBC progression depends on infiltration with immunocompetent cells, which can serve as a criterion for the disease prognosis. The prospect of further research – We are going to in-depth our research with studying importance of microenvironment of NIUBC, namely, immune cellular reactions, neoangiogenesis, connective tissue component at molecular-biological level. It will allow us to predict more accurate determination of NIUBC prognosis and choice of adequate treatment tactics.

The influence of the scrotal bipartition and of the year period on the scrotal-testicular thermal regulation was evaluated in male goats raised in Piaui State, Brazil. Eighteen male goats at mating age were accomplished in this study and arranged into three Groups (6 animals each) obeying the classification as goats presenting no scrotal bipartition (Group I), goats showing scrotal bipartition at 50% of the testicular length (Group II), and goats with more than 50% of scrotal bipartition (Group III). The scrotal, testicular and spermatic funiculi temperatures were evaluated invasively with the aid of a digital thermometer and non-invasive with a pyrometer in the proximal, medial and distal portion. The data were acquired during the dry (October-November) and rainy (February-March) period of the year, measured in two shifts: morning (6h00-7h00) and afternoon (14h00-15h00). The results were submitted to variance analysis (ANOVA) following the SNK test for average comparison (p<0.05). The year period interfered on the scrotal-testicular thermal regulation, due to increased temperatures of the scrotal, testicular and spermatic funiculi during the dry period in comparison with the rainy period. The bipartition level was also a factor which contributed to the influence of scrotal-testicular temperature regulation, due to lower average scrotal-testicular temperature rates observed during both periods in the goats with higher levels of scrotal bipartition (>50%). It is possible to conclude that with the experimental conditions applied on this study, the level of scrotal bipartition and the climatic conditions interfere with the scrotal-testicular thermal regulation in goats.
