RESUMEN

BACKGROUND: The objectives of this study were to evaluate the incidence of no-reflow as independent predictor of adverse events and to assess whether baseline pre-procedural treatment options may affect clinical outcomes. METHODS: Data were derived from the ISACS-TC registry (NCT01218776) from October 2010 to January 2015. No-reflow was defined as post-PCI TIMI flow grades 0-1, in the absence of post-procedural significant (≥25%) residual stenosis, abrupt vessel closure, dissection, perforation, thrombus of the original target lesion, or epicardial spasm. The outcome measure was in-hospital mortality. RESULTS: No-reflow was identified in 128 of 5997 patients who have undergone PCI (2.1%). On multivariate analysis, patients with no-reflow were more likely to be older (OR: 1.20, 95% CI: 1.01-1.44), to have a history of hypercholesterolemia (OR: 1.95, 95% CI: 1.31-2.91) and to be admitted with a diagnosis of STEMI (OR: 2.96, 95% CI: 1.85-4.72). Angiographic characteristics associated with no-reflow phenomenon were: stenosis ≥50% of the right coronary artery, presence of multivessel disease and pre-procedural TIMI blood flow grades 0-1. No-reflow was highly predictive of in-hospital mortality (17.2% vs. 4.2%; adjusted OR: 4.60, 95% CI: 2.61-8.09). Administration of pre-procedural unfractioned heparin or 600mg clopidogrel loading dose was associated with less incidence of no-reflow (OR: 0.65, 95% CI: 0.43-0.99 and 0.61, 95% CI: 0.37-1.00, respectively). Aspirin, enoxaparin, and 300mg clopidogrel loading dose, did not significantly impact the occurrence of the no-reflow. CONCLUSIONS: We found that pre-procedural administration of 600mg loading dose of clopidogrel and/or unfractioned heparin is associated with reduced incidence of no-reflow.

RESUMEN

BACKGROUND: Limited data are available on the outcome of primary percutaneous coronary intervention (PCI) in octogenarian patients, as the elderly are under-represented in randomized trials. This study aims to provide insights on clinical characteristics, management and outcome of the elderly and very elderly presenting with STEMI. METHODS: 2225 STEMI patients ≥70years old (mean age 76.8±5.1years and 53.8% men) were admitted into the network of the ISACS-TC registry. Of these patients, 72.8% were ≥70 to 79years old (elderly) and 27.2% were ≥80years old (very-elderly). The primary end-point was 30-day mortality. RESULTS: Thirty-day mortality rates were 13.4% in the elderly and 23.9% in the very-elderly. Primary PCI decreased the unadjusted risk of death both in the elderly (OR: 0.32, 95% CI: 0.24-0.43) and very-elderly patients (OR: 0.45, 95% CI 0.30-0.68), without significant difference between groups. In the very-elderly hypertension and Killip class ≥2 were the only independent factors associated with mortality; whereas in the elderly female gender, prior stroke, chronic kidney disease and Killip class ≥2 were all factors independently associated with mortality. Factors associated with the lack of use of reperfusion were female gender and atypical chest pain in the very-elderly and in the elderly; in the elderly, however, there were some more factors, namely: history of diabetes, current smoking, prior stroke, Killip class ≥2 and history chronic kidney disease. CONCLUSIONS: Age is relevant in the prognosis of STEMI, but its importance should not be considered secondary to other major clinical factors. Primary PCI appears to have beneficial effects in the octogenarian STEMI patients.

RESUMEN

BACKGROUND: We explored benefits and risks of an early invasive compared with a conservative strategy in women versus men after non-ST elevation acute coronary syndromes (NSTE-ACS) using the ISACS-TC database. METHODS: From October 2010 to May 2014, 4145 patients were diagnosed as having a NSTE-ACS. We excluded 258 patients managed with coronary bypass surgery. Of the remaining 3887 patients, 1737 underwent PCI (26% women). The primary endpoint was the composite of 30-day mortality and severe left ventricular dysfunction defined as an ejection fraction <40% at discharge. RESULTS: Women were older and more likely to exhibit more risk factors and Killip Class ≥2 at admission as compared with men. In patients who underwent PCI, peri-procedural myocardial injury was not different among sexes (3.1% vs. 3.2%). Women undergoing PCI experienced higher rates of the composite endpoint (8.9% vs. 4.9%, p=0.002) and 30-day mortality (4.4% vs. 2.0%, p=0.008) compared with men, whereas those who managed with only routine medical therapy (RMT) did not show any sex difference in outcomes. In multivariable analysis, female sex was associated with favorable outcomes (adjusted HR for the composite endpoint: 0.72, 95% CI: 0.58-0.91) in patients managed with RMT, but not in those undergoing PCI (adjusted HR: 0.96, 95% CI: 0.61-1.52). CONCLUSIONS: We observed a more favorable outcome in women than men when patients were managed with RMT. Women and men undergoing PCI have similar outcomes. These data suggest caution in extrapolating the results from men to women in an overall population of patients in the context of different therapeutic strategies.

RESUMEN

INTRODUCTION: Double orifice mitrol valve (DOMV) is a very rare congenital heart defect. CASE REPORT: We reported 20-year-old male referred to our center due to evaluation of his cardiologic status. He was operated on shortly after birth for a tracheoesophageal fistula. Accidentally, echocardiography examination at the age of 4 years revealed double orifice mitral valve (DOMV) without the presence of mitral regurgitation, as well as mitral stenosis, with normal dimensions of all cardiac chambers. The patient was asymptomatic, even more he was a kick boxer. His physical finding was normal. Electrocardiography showed regular sinus rhythm, incomplete right bundle branch block. Transthoracic echocardiography (ITE) examination revealed the normal size of the left atrial, mitral leaflets were slightly more redundant. The left and right heart chambers, aorta, tricuspid valve and pulmonary artery valve were normal. During TTE examination on a short axis view two asymmetric mitral orifices were seen as a double mitral orifice through which we registered normal flow, without regurgitation and mitral stenosis. Transesophageal echocardiography (TEE) examination from the transgastric view at the level of mitral valve, showed 2 single asymmetric mitral orifices separated by fibrous tissue, mitral leaflet with a separate insertion of hordes for each orifice. CONCLUSION: The presented patient with DOMV is the only one recognized in our country. The case is interesting because during 16-year a follow-up period there were no functional changes despite the fact that he performed very demanded sport activities. This is very important because there is no information in the literature about that.

RESUMEN

BACKGROUND: To evaluate the impact of comorbidities on the management and outcomes of acute coronary syndrome (ACS) patients without chest pain/discomfort (i.e. ACS without typical presentation). METHODS: Of the 11,458 ACS patients, enrolled by the International Survey of Acute Coronary Syndrome in Transitional Countries (ISACS-TC; ClinicalTrials.gov: NCT01218776), 8.7% did not have typical presentation at the initial evaluation, and 40.2% had comorbidities. The odds of atypical presentation increased proportionally with the number of comorbidities (odds ratio [OR]: 1, no-comorbid; OR: 1.64, 1 comorbidity; OR: 2.52, 2 comorbidities; OR: 4.57, ≥3 comorbidities). RESULTS: Stratifying the study population by the presence/absence of comorbidities and typical presentation, we found a decreasing trend for use of medications and percutaneous intervention (OR: 1, typical presentation and no-comorbidities; OR: 0.70, typical presentation and comorbidities; OR: 0.23, atypical presentation and no-comorbidities; OR: 0.18, atypical presentation and comorbidities). On the opposite, compared with patients with typical presentation and no-comorbidities (OR: 1, referent), there was an increasing trend (p<0.001) in the risk of death (OR: 2.00, OR: 2.52 and OR: 4.83) in the above subgroups. However, after adjusting for comorbidities, medications and invasive procedures, atypical presentation was not a predictor of in-hospital death. Independent predictors of poor outcome were history of stroke (OR: 2.04), chronic kidney disease (OR: 1.57), diabetes mellitus (OR: 1.49) and underuse of invasive procedures. CONCLUSIONS: In the ISACS-TC, atypical ACS presentation was often associated with comorbidities. Atypical presentation and comorbidities influenced underuse of in-hospital treatments. The latter and comorbidities are related with poor in-hospital outcome, but not atypical presentation, per se.

RESUMEN

BACKGROUND: A substantial proportion of elderly with ST segment elevation myocardial infarction (STEMI) do not undergo percutaneous coronary intervention (PCI). We sought to investigate factors associated with the decision not to perform coronary angiography at admission in these patients. METHODS: We evaluated 1315 STEMI patients aged ≥75years old enrolled in the International Survey of Acute Coronary Syndromes in Transitional Countries (ISACS TC) registry between October 2010 and February 2015. They were compared with 6667 patients aged <75years old enrolled in the registry in the same time frame. RESULTS: Elderly patients were less likely to undertake invasive coronary evaluation compared with younger patients (62.1% vs. 78.9; p<0.001%). In the older group there were a lower proportion of patients presenting <12h after symptom onset (66.5% vs.76.9%, p<0.001), and a higher prevalence of comorbidities. Few elderly were treated with current recommended evidence based treatments (aspirin, clopidogrel, heparins, beta-blocker, statins, and ACE-inhibitors). Logistic analysis adjusted for age and sex showed that older age was associated with underuse of coronary angiography (OR 0.46, 95% CI: 0.41-0.53, p<0.001). Clinical factors that were associated with underuse of angiography in patients over 75 were: female sex (OR: 0.77), presence of comorbidities (OR: 0.91), anemia (OR: 0.44) and late hospital admission (OR: 0.89). CONCLUSIONS: In the ISACS-TC, more than one third of the elderly with STEMI did not undergo coronary angiography at admission. Sex, comorbidities, and late hospital admission were independent factors associated with the underuse of PCI in these patients.

RESUMEN

BACKGROUND: Guidelines recommend use of evidence-based medications in patients discharged after an acute coronary syndrome (ACS). Yet the current rates of adherence in many eastern European countries are unknown. OBJECTIVE: To determine whether 6month outpatient follow-up after ACS is associated with recommended rates of medication adherence in Montenegro. METHODS: A prospective analysis was conducted in 585 ACS patients confirmed to be alive after ACS at 6month follow-up. The study was undertaken between 2012 and 2015, from 9 International Survey of Acute Coronary Syndrome in Transitional Countries (ISACS-TC) hospitals in the Montenegro. The primary outcome was guideline-concordant care, defined as 100% compliance with 5 medications: aspirin, clopidogrel, beta-blockers, and statins in ACS patients, and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers [ACEI/ARB] for the subset of patients with left ventricular systolic dysfunction, as assessed by an ejection fraction less than 40% at discharge. In addition to the composite end point, the achievement of each single treatment measure was analyzed. Multivariate predictors of long-term medication adherence were also identified. RESULTS: Guideline-concordant care (GCC) at discharge increased from 2012 to 2015 (adjusted OR for increase 1.51; CI 0.88-2.52). GCC over 6months was adhered in 73% of patients. In patients who did not achieve GCC, adherence was persistently high with 92.3% for aspirin, 91.3% for statins and 72% for ACE-inhibitors or angiotensin-receptor blockers (ARBs). Adherence was lower for clopidogrel (57.7%) and beta-blockers (64.4%). After adjusting for demographic and clinical differences, in-hospital referral to PCI and ST segment elevation myocardial infarction (STEMI) were associated with greater medication adherence at 6month follow-up. CONCLUSIONS: In Montenegro, long-term adherence to evidence-based medication after ACS is high. Adherence to guideline-recommended therapies increased over time with participation to the ISACS-TC. The lower achievement of GCC in patients treated medically and in those with non-ST-segment elevation ACS needs particular attention.

RESUMEN

The aim of this study was to determine if earlier administration of oral ß â€‹blocker therapy in patients with acute coronary syndromes (ACSs) is associated with an increased short-term survival rate and improved left ventricular (LV) function. We studied 11,581 patients enrolled in the International Survey of Acute Coronary Syndromes in Transitional Countries registry from January 2010 to June 2014. Of these patients, 6,117 were excluded as they received intravenous ß blockers or remained free of any ß â€‹blocker treatment during hospital stay, 23 as timing of oral ß â€‹blocker administration was unknown, and 182 patients because they died before oral ß blockers could be given. The final study population comprised 5,259 patients. The primary outcome was the incidence of in-hospital mortality. The secondary outcome was the incidence of severe LV dysfunction defined as an ejection fraction <40% at hospital discharge. Oral ß blockers were administered soon (≤24 hours) after hospital admission in 1,377 patients and later (>24 hours) during hospital stay in the remaining 3,882 patients. Early ß â€‹blocker therapy was significantly associated with reduced in-hospital mortality (odds ratio 0.41, 95% CI 0.21 to 0.80) and reduced incidence of severe LV dysfunction (odds ratio 0.57, 95% CI 0.42 to 0.78). Significant mortality benefits with early ß â€‹blocker therapy disappeared when patients with Killip class III/IV were included as dummy variables. The results were confirmed by propensity score-matched analyses. In conclusion, in patients with ACSs, earlier administration of oral ß â€‹blocker therapy should be a priority with a greater probability of improving LV function and in-hospital survival rate. Patients presenting with acute pulmonary edema or cardiogenic shock should be excluded from this early treatment regimen.

RESUMEN

AIMS: Widespread availability of tertiary hospitals with catheterization facilities, although vigorously promoted, has yet to become a reality in many countries with economy in transition. We sought to evaluate the clinical profile and mortality of patients who were hospitalized with a diagnosis of ST-segment elevation myocardial infarction (STEMI) and either received reperfusion therapy or remained without reperfusion in Eastern Europe. METHODS AND RESULTS: Data were obtained from the International Survey of Acute Coronary Syndromes in Transitional Countries (ISACS-TC; NCT01218776) on STEMI patients admitted to 57 hospitals in Eastern European countries from January 2010 to February 2015. The primary endpoint was 30-day mortality. Of 7982 patients, 65 (0.8%) had a documented contraindication to reperfusion, 5973 (75.5%) received fibrinolysis ( n = 1032) or underwent primary percutaneous coronary intervention (p-PCI; n = 4941), and 1944 patients (24.6%) did not receive any reperfusion therapy. The overall unadjusted 30-day mortality rate was 7.9%. Thirty-day mortality rates were higher in non-reperfusion patients (16.0 vs. 5.0% in the p-PCI group and 7.4% in fibrinolysis group). The strongest factors associated with not attempting reperfusion therapy among these patients were female sex (OR 1.29 CI 1.07-1.56), age (OR 1.02; CI 1.01-1.03), prior MI (OR 1.79; CI 1.38-2.32), prior cerebrovascular events (OR 1.87; CI 1.30-2.68), chronic kidney disease (OR 1.76; CI 1.22-2.53), Killip class >1 (OR 1.31; CI 1.06-1.62), and time to admission >12 h (OR 15.9; CI 13.1-19.3). CONCLUSIONS: A substantial number of patients are still not offered any reperfusion therapy in many Eastern European countries with economy in transition, and this was associated with increased 30-day mortality. Time from symptoms onset to admission >12 h was the highest ranking among factors related to lack of reperfusion therapy. Quality improvement efforts should focus on minimizing delay to hospital admission among STEMI patients.

RESUMEN

OBJECTIVE: We sought explore the relative benefits of unfractionated heparin (UFH) compared with enoxaparin, alone or in combination with clopidogrel, in ST-segment elevation myocardial infarction (STEMI) patients not undergoing reperfusion therapy. METHODS: This is a propensity score study from The International Survey on Acute Coronary Syndromes in Transition Countries (ISACS-TC/NCT01218776) on patients admitted between October 2010-June 2013. There were a total of 1175 STEMI patients who did not receive mechanical or pharmacological reperfusion. Of these, 1063 were eligible for the aim of the study, being treated with UFH (522/1175; 44.4%) or enoxaparin (541/1175; 46%). Clopidogrel in combination with UFH or enoxaparin was given to 751 (63.9%) patients. The primary endpoint was in-hospital mortality. Secondary endpoints were intracranial hemorrhages, and clinically relevant bleedings. RESULTS: After adjustment for any confounders, UFH was associated with a lower risk of in-hospital mortality in clopidogrel users (multivariate adjusted regression analysis: odds ratio [OR]: 0.62, 95% Confidence Interval [CI] 0.41-0.94) as compared with clopidogrel non-users (OR: 0.94, 95% CI 0.55-1.60). The observed effect was not associated with combined enoxaparin and clopidogrel therapy. Major bleeding events were comparable in the enoxaparin group and UFH group (0.4% and 1.5% respectively, p = 0.06). The risk of major hemorrhage was nearly similar with combined UFH-clopidogrel therapy (1.4%) as compared with UFH alone (1.9%), p = 0.67. CONCLUSION: UFH - Clopidogrel combination was associated with a large mortality reduction in STEMI patients not undergoing reperfusion therapy and did not significantly increase the risk of major bleeding.

RESUMEN

BACKGROUND/AIM: Depressed heart rate variability (HRV) indicating autonomic disequilibrium and propensity to ventricular ectopy can be useful for risk stratification in patients following acute myocardial infarction (AIM). The aim of the study was to assess heart rate variability as a predictor of all-cause mortality in post-infarction patients. METHODS: We analyzed the 24-hour electrocardiographic (ECG) recordings of 100 patients (80 males) during hospitalization for AIM: The mean age of patients was 56.99 + 11.03 years. Time domain heart rate variability analysis was obtained from 8 to 13 days after index infarction by mean of a 24-hour ECG recording, and the calculated parameters were: standard deviation of all normal to normal RR intervals (SDNN), RRmax-RRmin (difference between the longest RR interval and the shortest RR interval), mean RR interval. We also analyzed ventricular premature complexes from the ECG data. The patients underwent clinical evaluation, laboratory tests and echocardiography. RESULTS: Within a one-year follow-up period 11 patients experienced death, 10 of them because of cardiac reason and one because of stroke. There were significantly lower values of SDNN (60.55 ± 12.84 ms vs 98.38 ± 28.21 ms), RRmax-RRmin (454.36 ± 111.00 ms vs 600.99 ± 168.72 ms) and mean RR interval (695.82 ± 65.87 ms vs 840.07 ± 93.97 ms) in deceased patients than in the survivors, respectively (p < 0.01). The deceased patients were of higher mean age, with lower left ventricular ejection fraction (0.46 ± 0.05 vs 0.56 ± 0.06 in survivors), and more frequent clinical signs of heart failure and ventricular ectopic activity (> 10VPCs/h; p < 0.01). Multivariate Cox analysis showed that SDNN was a significant, independent predictor of all-cause mortality in post-infarction patients. The other independent predictors were clinical signs of heart failure--Killip class II and III and ventricular ectopic activity. CONCLUSION: Depressed HRV is an independent predictor of mortality in post-infarction patients and may provide useful additional prognostic information in non-invasive risk stratification of these patients.

RESUMEN

The impact of late percutaneous coronary intervention (PCI) in the patients after acute myocardial infarction (AMI) on long term mortality remains to be established. At currently, thrombolysis is accepted as standard therapy when PCI is not immediately available. However, PCI is often performed in stable patients with AMI who are/are not received thrombolysis . We performed the trial that enrolled myocardial infarction patients treated with thrombolysis, late PCI and medically to assess the potential benefits of delayed PCI. We follow up 164 consecutive patients after AMI one year. The patients are divided in two groups; first group-66 patients who received reperfusion (37 patients received only thrombolysis, 10 patients received thrombolysis and PCI 7-9 days after thrombolysis and 19 patients underwent only PCI after 7-9 days) and second group-98 patients medically treated. One year mortality was 3% in the reperfusion group (2/66) and 14,3% in the medical group (14/98) (p=0,016). There were not significant differences between groups about other end points-reinfarctus, coronary artery bypass surgery and PCI performed later after discharge. The major predictors of one year mortality were ages (p<0,001) and ejection fraction (p=0,003). Also, therapy with beta-blockers (p=0,002), statins (p=0,001) and ACE-inhibitors (p=0,024) was associated with better survival. Delayed PCI performed 7-9 days after AMI in the patients who underwent thrombolysis or those did not improves outcome at long-term follow-up.

RESUMEN

INTRODUCTION: Patients with non-ST elevation acute coronary syndromes (NSTE-ACS) are sometimes severely hemodynamicly compromised. Urgent coronary angiography should be performed in these patients in percutaneous coronary intervention (PCI) centers according to the ESC NSTE-ACS guidelines to determine suitabilty for percutaneous or surgical revascularization. CASE REPORT: We reported a 62-year-old male with chest pain admitted to the Coronary Care Unit. ST segment depression of 2 mm in leads I, L and V4-6 was revealed at electrocardiogram. After following 6 hours the patient had chest pain and signs of cardiogenic shock despite of the therapy. Chest xray showed pulmonary edema. Echocardiographic examination showed dyskinetic medium and apical segments of septum. The patient underwent coronary angiography immediately which revealed 75% stenosis of the left main coronary artery with thrombus. The use of a GPIIb/III inhibitor-tirofiban and stent implantation resulted in TIMI III flow. After that the patient had no chest pain and acute heart failure subsided in the following days Echocardiography done at the fourth day from PCI showed only hypokinesis medium and apical segment of septum. The patient was discharged at day 11 from admission in a stable condition. CONCLUSION: Stenting of left main coronary artery stenosis in patients with cardiogenic shock and non-ST segment elevation acute coronary syndromes may be a life saving procedure.

RESUMEN

The aim of this trial was to examine the effects of antihypertensive fixed combination of lisinopril plus hydrochlorothiazide (Lopril H, Bosnalijek dd, Bosnia and Herzegovina) on regression of left ventricular hypertrophy in patients with essential arterial hypertension. We included 297 patients in our trial, aged 54.65+/-9.6 years, with treated or untreated hypertension and with high risk of cardiac events, in an opened trial of therapy based on lisinopril plus hydrochlorothiazide. Patients from five European countries were followed up for a period of 12 weeks. Duration of treatment was 12 weeks. We adjusted daily doses of lisinopril plus hydrochlorothiazide after every clinical examination and recorded adverse effects of drugs. In the beginning and after 12 weeks of treatment, 277 patients (93.2%) underwent 2-dimensional echocardiography and there were 186 patients evaluated for efficacy of treatment on left ventricular hypertrophy (LVH). We recorded a regression of index mass LVH (168.56 vs 161.51 g/m2, P<0.0001), and regression was something more in women vs men. We recorded average reduction of left ventricular mass index for patients with LVH (N=186) by 7.05 g/m2 (4.18%) in all patients, by 6.73 g/m2 (3.93%) in men and 7.27 g/m2 (4,37%) in women. The proportion of patients who attained a regression of left ventricular mass tended to be greater in men (54.55% vs 53.21%). This research has proved regression of LVH in more than 53% patients after using fixed combination of lisinopril plus hydrochlorothiazide.

RESUMEN

The aim of this trial was to examine the efficacy and safety of antihypertensive fixed combination lisinopril plus hydrochlorothiazide (Lopril H, Bosnalijek dd) in the treatment of essential arterial hypertension. In our trial we included 297 patients, aged 54.65+/-9.6 years, with treated or untreated hypertension and with high risk of cardiac events, in an opened trial of therapy based on lisinopril plus hydrochlorothiazide. Upon the examination by physicians, patients were divided into three groups in accordance with European Society of Cardiology guidelines for the management of arterial hypertension. Patients from five European countries were followed up for a period of 12 weeks. Duration of treatment was 12 weeks. We adjusted daily doses of lisinopril plus hydrochlorothiazide after every clinical examination and recorded adverse effects of drugs. After 12 weeks of treatment, 288 patients (96%) were evaluated for efficacy, tolerability and safety. In almost 81.5% patients with mild, moderate and severe hypertension, we recorded a reduction in blood pressure to approximately normal values SBP and DBP (140/90 mmHg). Drug-related side-effects occurred in 11 patients (3.66%). The most commonly reported adverse effects associated with lisinopril plus hydrochlorothiazide were cough (5) and dry mouth (5). This research has proved good efficacy of fixed combination lisinopril plus hydrochlorothiazide with more than 97% patients. Based on subjective estimation by patients: this drug improved quality of life in all cases.
