RESUMO

Congenital heart disease (CHD) is the most common inborn defect. Due to advances in paediatric care, surgical, and catheter procedures the number of adults with CHD has grown remarkably in recent years. Most of these patients, however, have residua from their original operation/s and require life-long care, many of them are subjected to further haemodynamic and electrophysiological interventions during adulthood. While such re-do surgical or catheter interventions together with device therapy and transplantation play a key therapeutic role, increasingly, adults with CHD require drug therapy for late complications namely heart failure (HF), arrhythmias, pulmonary and systemic hypertension, thromboembolic events, etc. Unlike other cardiovascular areas, drug therapy in adult CHD is based on scarce clinical data and remains largely empiric. Consequently, pharmacological therapies are individualized to ameliorate patients' symptoms and/or degree of haemodynamic impairment. Thus far, recommendations have been difficult to make and formalized guidelines on drug therapy are lacking. We review herewith the rationale, limited evidence and knowledge gaps regarding drug therapy in this growing cardiovascular field and discuss pharmacotherapy options in specific conditions namely HF, arrhythmias, thrombosis, pulmonary arterial hypertension, contraception, and pregnancy.

RESUMO

BACKGROUND: Budd-Chiari syndrome is defined as a hepatic venous outflow track obstruction of various etiology, which appears at different levels. The inferior vena cava outflow membrane is an unusual, but a potentially treatable cause. The percutaneous treatment has emerged as a very promising management mode for such patients. Follow-up results are favorable for balloon angioplasty and/or stenting, with minimal re-stenosis rates. CASE PRESENTATION: We report a case of a young woman, earlier operated on congenital heart defect and with previous pulmonary embolic incident after childbirth, with no evidence of thrombophilia. She was admitted to our institution for a suspected right atrial tumor. After the diagnosis of Budd-Chiari syndrome caused by membranous inferior vena cava obstruction, a percutaneous treatment of a thick membrane was successfully performed, using an unusual technique. CONCLUSION: Balloon angioplasty should be considered in cases of membranous obstruction of vena cava, where a focal obstruction is causing the symptoms. In our patient, the anatomy was not suitable for stenting, and balloon dilatation was successful just after the membrane was pulled apart with a big balloon in a "Rashkind-like" procedure.

RESUMO

BACKGROUND: Patients with repaired tetralogy Fallot often develop severe pulmonary regurgitation (PR) and need surgical or catheter valve replacement/implantation. Early valve failure is not expected and thrombosis of a biological valve in a mid-term period after surgery on pulmonary position is rare. CASE SUMMARY: We report a 33-year-old female patient, who presented with heart failure, 18 months after surgical implantation of a biological valve on pulmonary position for severe PR, after previous complete repair. The patient was on anticoagulant therapy with novel oral anticoagulants (NOACs) for paroxysmal atrial fibrillation. After revealing a big pulmonary valve (PV) thrombus as a cause of severe valve stenosis and right heart failure, patient was re-operated without complication. After surgery a long-term warfarin therapy was introduced. The patient had an uneventful 9-month follow-up. DISCUSSION: Thrombotic events after rivaroxaban therapy are rare in non-valvular disease and there is paucity of data for NOAC therapy related to valve thrombosis. In our case, severe heart failure 1 year and a half after PV replacement, in a patient taking anticoagulant therapy, was unexpected. The diagnosis of valve thrombosis was revealed by echocardiography, and confirmed by computed tomography. We did not find any sign of thrombophilia, or any mechanical reason for valve thrombosis.

RESUMO

BACKGROUND: The optimal treatment of patients undergoing percutaneous coronary interventions (PCI) for lesions located at coronary bifurcations is still debated. METHODS: Data on 5036 consecutive patients who underwent PCI on coronary bifurcation at 17 major coronary intervention centers between January 2012 and December 2014 were collected. RESULTS: Follow-up at a median 18 months (IQR 11-28) was available for 4506 patients (89%). Major Adverse Cardiac Events (MACE) occurred in 395 patients (8.8%): cardiac death in 152 (3.4%), myocardial infarction, excluding periprocedural, in 156 (3.5%) and stent thrombosis in 110 cases (2.4%). At multivariable Cox regression, left ventricular ejection fraction ≤30% (P < 0.001), bail-out stenting (beyond a planned strategy of either single or double stenting) (P < 0.001), admission for an acute coronary syndrome (P < 0.001), age >66 years (P < 0.001), multivessel disease (P < 0.001) and diabetes (P < 0.001) were independently associated with MACE. Sensitivity analysis identified premature discontinuation of dual antiplatelet therapy (DAPT) (P < 0.001) and side branch (SB) lesion length ≥9 mm (P < 0.05) as additional independent predictors of MACE. CONCLUSIONS: Beyond traditional risk factors, multivessel disease, the length of the SB lesion, "bail-out" stenting and premature DAPT discontinuation are independent predictors of mid-term MACE after PCI of coronary bifurcations. This highlights the importance of a carefully planned PCI strategy and adequate therapy adherence to improve the clinical outcomes in these patients.

RESUMO

6497 consecutive patients who underwent coronary angiography in our institution in a three-year period were analysed. Spontaneous coronary artery dissection was noted in five, and unexpected dissection secondary to coronary arteriography in three patients. All patients with spontaneous dissection presented clinically as myocardial infarction. Three patients (two of them with spontaneous dissection) underwent urgent coronary artery bypass grafting. Percutaneous coronary intervention was successful in two patients with spontaneous and in one with unexpected secondary dissection. One patient with spontaneous and one with secondary dissection were treated medically after failed intervention. In conclusion, spontaneous coronary artery dissection is rare, but not exceptional. Its true incidence might have been underestimated before the advent of coronary interventions in acute myocardial infarction. Survival of all our patients, in contrast to earlier reports on mortality rates up to 50%, may be attributed to the benefits of modern surgery and interventional cardiology.

RESUMO

Access site complications are major source of morbidity following cardiac catheterization. Their incidence varies in the literature because of multiple definitions and methods of determining the presence of particular complication. The aim of this prospective study was to determine the incidence of access site complications following cardiac catheterization using arterial duplex ultrasonography. A total of 319 consecutive patients, who had cardiac catheterization underwent femoral artery duplex study 24 to 48 hours following manual hemostasis. Diagnostic angiogram had 232 (71.8%) while 87 (28.2%) had percutaneous coronary intervention (PCI). Femoral artery duplex ultrasound was normal in 247 (77.4%). Haematoma was found in 48 (15.1%), pseudoaneurysm in 17 (5.3%), AV fistula in 2 (0.6%) and dissection of the femoral artery in 5 (1.6%) patients. Baseline demografic characteristics were similar in group with normal duplex study and group with detected complication. Pseudoaneurysm and AV fistula were more commonly observed in patients following PCI than diagnostic angiogram (9.2% vs. 4.7%, p<0.001). Patients with documented complications more frequently had concomitant administration of antiplatelet and anticoagulant medication compared to the patients without complications (p=0.003). Hemodynamic disturbances (hypotension and bradycardia) during manual compression were more frequent in patients with complication (11% vs. 4.5%, p=0.047). Low threshold for use of duplex ultrasound should be exercised in patients following cardiac catheterization to establish the presence of access site complications. Special attention is needed in the setting of aggressive antiplatelet and anticoagulant therapy, interventional procedures and hemodynamic disturbances during manual hemostas.

RESUMO

AIM: To compare polytetrafluoroethylene stent graft (PTFE) with sirolimus and bare metal stents in reducing in-stent restenosis in native coronary vessels in patients with acute coronary syndrome. METHODS: The study included patients who underwent stent implantation in acute coronary syndrome from January 2003 to May 2004. The patients (n=119) were randomized either to stent graft group (n=40), sirolimus eluting stent group (n=39), or bare metal stent group (n=40). The main outcome measure of the study was the incidence restenosis at 6-month. The secondary outcome was 6-month major adverse coronary event rate. RESULTS: The incidence of 6-month major adverse coronary events was similar in all three groups (8 events in stent graft, 9 in sirolimus eluting stent, and 16 in bare metal stent group events). The target lesion revascularization was higher in the bare metal stent group (P=0.044). Restenosis rate, at six-month follow-up was higher in the bare metal stent group compared with the stent graft and sirolimus eluting stent groups. The percent diameter stenosis in the follow-up was significantly higher in the bare metal stent group (P=0.005). The late loss was significantly lower in the sirolimus eluting stent group (mean+/-standard deviation, 0.2+/-0.5 mm), compared with the bare metal stent group (0.7+/-0.7 mm, P=0.034). There was a trend of lower late loss in the stent graft group than in the bare metal stent group. CONCLUSION: Three groups of stents implanted in patients with acute coronary syndrome did not differ in the incidence of major adverse cardiac events. Sirolimus-eluting stents had a lower incidence of in-stent restenosis than bare metal stent group. Stent graft implanted in native coronary arteries appears to be safe and efficient in patients with acute coronary syndrome, but a significant reduction in in-stent restenosis was not achieved.

RESUMO

In Coronary Care Unit and Intensive Care Unit, Zagreb University Hospital Centre, 403 patients were hospitalized for acute myocardial infarction (AMI) in the year 2005. Majority (288) patients presented with ST-segment elevation myocardial infarction (STEMI) and 115 patients with acute myocardial infarction without ST-segment elevation (NSTEMI). In-hospital mortality of STEMI patients was 13.9% vs. 9.6% of NSTEMI group of patients. In STEMI group 202 patients underwent urgent percutaneous coronary intervention (PCI), and 86 patients in STEMI group received conservative therapy. In-hospital mortality of patients treated with primary PCI was 5.9% vs. 29.1% in the group treated conservatively. The main reason for conservative therapy was late presentation to the hospital (> 12 hours from the beginning of symptoms). Only 11 high-risk patients in NSTEMI group underwent primary PCI and 99 NSTEMI patients received conservative therapy (in-hospital mortality 10.1%). We performed totally 218 urgent PCI interventions in both groups with low in-hospital mortality of 6.1% in comparison with high mortality in conservatively treated groups of patients. The mortality in PCI group was strongly connected with unsuccessful intervention and late reperfusion. Total ischemic time (6 hours and 5 minutes), and time from hospital presentation to reperfusion -"door to balloon time" (1 hour and 25 minutes) are longer that in similar patients series, and need to be improved. Transportation time (1 hour and 40 minutes) is acceptable. In conclusion, high percentage (70.1%) of STEMI and NSTEMI patients underwent primary PCI in our institution with low perioperative mortality. This group of patients had superior in-hospital mortality when compared with conservatively treated group of patients. There is still unacceptably high percentage of patients with AMI, who came into the hospital too late for any reperfusion therapy.

RESUMO

The aim of this study was to explore the relation between atherosclerosis of the retinal arteries and the extent and severity of coronary artery disease (CAD). In 109 patients, aged 40 to 80 years, who underwent coronary angiography for suspected CAD, the degree of retinal arterial atherosclerosis (stages 1 to 4 according to Scheie) was determined. The fundus examination was done using direct ophthalmoscopy by an ophthalmologist blinded to the extent of the CAD. The CAD extent was evaluated by Gensini score, and coronary angiograms were analyzed by 2 expert observers who had no knowledge of the patients' retinal artery status. The extent and severity of retinal vessel atherosclerosis correlated strongly with the extent and severity of CAD. Thus, atherosclerotic changes in the retinal arteries may be a predictor of the extent of CAD.

RESUMO

We perform primary angioplasty in all acute myocardial infarction patients with ST elevation in the first 6 hours, with good results. In 30 selected patients (36.2% of all primary angioplasty patients in this period) we used the method od direct stenting with 100% primary success. In all patients we achieved TIMI 2-3 flow, and complete or partial ST elevation resolution. The early mortality rate was 3.3%, and no other complications arose. Direct stenting in primary coronary angioplasty is a safe and effective procedure, with high primary result in selected cases, and low complication rate during procedure and incidence of MACE (Mayor Adverse Cardiac Events) during hospital stay and after 6 month follow up. The results are comparable with standard interventional procedure in acute myocardial infarction, with the advantage of shorter procedure, lower radiation exposure and less material use.

RESUMO

Over the last ten years, transradial cardiac catheterization has been increasingly applied, primarily because of its lower incidence of complications compared to the femoral approach. However, one of the greatest flaws of the transradial approach is a relatively high incidence of catheterization failure (1%-5%). Anatomic variations of radial artery are ranked second among the reasons for this. Previous studies have not provided unambiguous data on the frequency of these anomalies. It was therefore the aim of this study to determine the frequency of anatomic variations using routine angiographies of radial artery during left heart catheterization. This was a retrospective study involving examination of 602 images of routine angiographies of radial artery performed during cardiac catheterization. The frequency of anatomic variations of radial artery was 8.8%, exclusive of tortuosities with a frequency of 12.7%. The most frequent anatomic variation was the high origin of radial artery, found in 31 (5.1%) subjects. Radioulnar loops, being one of the potential contraindications for the procedure, were reported in 2% of cases. Regression analysis revealed that age (p < 0.001), female sex (p = 0.015) and high origin (p = 0.034) considerably contributed to the development of tortuosity. The results indicated the incidence of tortuosity to increase linearly with age. Although it is not a contraindication for continuing with the procedure, we recommend that elderly patients have angiography of radial artery performed at the beginning of the procedure due to the higher frequency of tortuosity.

RESUMO

BACKGROUND: We compared efficacy of bare-metal stent (BMS) and drug-eluting balloon (DEB) combination vs BMS alone, in patients with non-ST elevation acute coronary syndrome treated with percutaneous coronary intervention (PCI). METHODS: Patients with non-ST elevation myocardial infarction (NSTEMI) or unstable angina (UA) were randomized to BMS only or BMS+DEB group. Angiographic follow-up was performed after 6 months. The primary endpoints were binary in-stent restenosis (ISR) and late lumen loss (LLL) and the secondary endpoints were target lesion revascularization (TLR), stent thrombosis (ST), and new acute coronary syndrome (ACS). RESULTS: A total of 85 patients were enrolled, 44 (BMS) and 41 (BMS+DEB). The median age was 67 (36-84) years and 68 (80%) were male. Fifty-two patients (61.2%) had NSTEMI and 33 patients (38.8%) UA. There was no difference in patient demographics, risk factors, and clinical characteristics, except for more smokers in the BMS+DEB group 18/41 (43.9%) vs 9/44 (20.5%). At follow-up, no significant difference in binary ISR was found; p=0.593, but LLL was significantly lower in the BMS+DEB group 0.68 (0.00-2.15) mm vs 0.22 (0.00-2.35) mm; p=0.002. The difference in major adverse cardiac events (MACE) rate combining TLR, ST, and ACS, between the groups was also non-significant, 29.5% (BMS) vs 24.4% (BMS+DEB); p=0.835. One patient had a subacute ST (BMS+DEB) due to clopidogrel resistance. CONCLUSION: Patients treated with BMS+DEB combination for non-ST elevation acute coronary syndrome had significantly less LLL in comparison to patients treated with BMS alone but without an impact on patient clinical outcomes.

RESUMO

PURPOSE: The aim of this research was to investigate the association of chronic and aggressive periodontitis with the severity of coronary artery disease which was angiographically verified. MATERIAL AND METHODS: Subjects were selected among the hospitalized patients at the University Hospital Centre Zagreb who had coronary angiography done because of the chest pain. Thorough clinical examination included periodontal indices and clinical and socio-demographic characteristics of participants. Subjects were divided in two test groups, acute coronary syndrome (ACS) and stable coronary artery disease (CAD), and the control group with no significant CAD. Data were analyzed using Kruskal-Wallis and Pearson's Chi-Square test. RESULTS: From 106 subjects, 66 (62.3%) were hospitalized for ACS, 22 (20.7%) had stable CAD and only 18 (17.0%) had no significant CAD. Only 26 (24.5%) out of 106 patients were never smokers (p<0.05). Chronic periodontitis was the most common finding with 68.2% in ACS group and 54.5% in stable CAD group, while healthy patients without periodontitis (72.6%) were dominant in the control group (p<0.001). Stable CAD group had the highest mean probing depth (PD) 3.92±1.16, gingival recession (GR) 1.34±0.78, clinical attachment level (CAL) 4.60±1.41 and bleeding on probing (BOP) 45.98±26.19 values, whereas ACS group had mean PD value of 3.77±0.91, GR 1.11±0.66, CAL 4.32±1.08 and BOP 41.30±22.09, and no significant CAD group had mean PD value of 3.27±0.97, GR 0.69±0.37, CAL 3.62±1.04 and BOP 26.39±13.92 (p<0.05). CONCLUSION: Periodontitis was shown to be associated with angiographically verified coronary artery disease. Physical inactivity, poor oral hygiene and periodontal inflammation were observed in patients with ACS and stable CAD.

RESUMO

OBJECTIVES: The objective of this study was to determine the long-term efficacy and dynamics of systolic and diastolic luminal changes within the bridged segments of coronary arteries after intracoronary stenting with drug-eluting stent (DES) in patients (pts) with symptomatic myocardial bridging (SMB) in the absence of coronary atherosclerosis. BACKGROUND: Although myocardial bridging (MB) represents a benign disease in the majority of pts, in its severest forms it is clinically manifested as typical or atypical angina, myocardial ischemia, myocardial infarction, left ventricular dysfunction, atrioventricular conduction disturbance, exercise-induced ventricular tachycardia, or sudden death. The only existing prospective study of 11 pts with SMB treated with bare-metal stent (BMS) reported a 36% in-stent restenosis (ISR) rate at 7 weeks repeated quantitative coronary angiography (QCA). METHODS: The study consisted of 15 consecutive patients (13 men and 2 women) with SMB of the mid-portion of the left anterior descending (LAD) coronary artery (and in 1 patient, concomitant MB of the left circumflex [LCX] coronary artery) and luminal diameter systolic narrowing of the tunneled segment of ≥50%, underwent percutaneous coronary intervention with DES. Clinical and non-invasive assessments of myocardial ischemia were determined every 6 months over 5 years and QCA was performed 12 and 24 months post procedure if not urged differently by deterioration of clinical symptoms and/or presence of positive ischemia tests. The minimal systolic and diastolic luminal diameters of the bridged/stented segments were measured before, immediately after, and 12 and 24 months post procedure by two independent observers blinded to each other's readings, using QCA commercial software. The endpoints of the study were ISR, target lesion revascularization (TLR) rate, in-stent diameter late luminal loss (LLL), and permanent disappearance or significant improvement of clinical symptoms. RESULTS: After 12 months, ISR and TLR in 16 treated vessels was 18.7%, LLL was 0.2 ± 0.6 mm and permanent disappearance or significant improvement of symptoms was achieved in all 15 pts. In 3 pts, clinically-driven repeat revascularization was necessary within the first 6 months. In 1 patient, coronary perforation complicated stent deployment and was immediately resolved by stent-graft implantation, followed by completely uneventful recovery. CONCLUSIONS: DES implantation in pts with SMB resistant to medical treatment results in prompt and long-term increase of systolic and diastolic luminal diameters, and long-lasting relief of clinical symptoms. Compared to BMS, stenting of SMB with DES resulted in significantly lower ISR and TLR rate.

RESUMO

OBJECTIVES: This study sought to investigate the impact of successful manual thrombus aspiration on angiographic in-stent restenosis and clinical outcome in patients treated by bare metal stent implantation for ST-segment elevation acute myocardial infarction. BACKGROUND: There are very limited data on the impact of manual thrombus aspiration on the occurrence of in-stent restenosis after bare metal stent implantation. METHODS: This was a prospective, randomized, single-center study. Patients (N=60) presenting within 12 h of ST-segment elevation acute myocardial infarction symptom onset were randomized to primary percutaneous coronary intervention (PCI) with (N=30) or without (N=30) upfront manual thrombus aspiration using the Export aspiration catheter. All patients underwent control coronary angiography after 6 months. RESULTS: Baseline, clinical, and angiographic preprocedural findings did not differ between the two groups. Patients who underwent successful manual thrombus aspiration had significantly higher minimal lumen diameter after 6 months (2.25±0.90 vs. 1.63±0.76, P=0.005), significantly lower percentage diameter stenosis (28.81 vs. 45.03%, P=0.017), and significantly lower late lumen loss (0.73±0.84 vs. 1.18±0.79, P=0.035). There was a trend for lower rate of major adverse cardiocerebrovascular events such as death, myocardial reinfarction, stroke, and target lesion revascularization in the same group of patients (16.67 vs. 26.67%, P=0.347). CONCLUSION: Successful upfront manual thrombus aspiration during primary PCI showed beneficial effects on the reduction of in-stent restenosis after bare metal stent implantation compared with standard PCI.

RESUMO

The aim of the study was to evaluate the influence of door-to-balloon time and symptom onset-to-balloon time on the prognosis of patients with acute ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI) in the Croatian Primary PCI Network. A total of 1190 acute STEMI patients treated with primary PCI were prospectively investigated in eight centers across Croatia (677 non-transferred, 513 transferred). All patients were divided according to door-to-balloon time in three subgroups (< 90, 90-180, and > 180 minutes) and according to symptom onset-to-balloon time in three subgroups (<180, 180-360, and > 360 minutes). The postprocedural Thrombolysis in Myocardial Infarction flow, in-hospital mortality, and major adverse cardiovascular events (mortality, pectoral angina, restenosis, reinfarction, coronary artery by-pass graft and cerebrovascular accident rate) in six-month follow-up were compared between the subgroups. The Croatian Primary PCI Network ensures results of treatment of acute STEMI comparable with randomized studies and registries abroad. None of the result differences among the door-to-balloon time subgroups was statistically significant. Considering the symptom onset-to-balloon time subgroups, a statistically significant difference at multivariate level was highest for in-hospital mortality in the subgroup of patients with longest onset-to-balloon time (4.5 vs. 2.6 vs. 5.7%; p = 0.04). Door-to-balloon time is one of the metrics of organization quality of primary PCI network and targets for quality improvement, but without an impact on early and six-month follow-up results of treatment for acute STEMI. Symptom onset-to-balloon time is more accurate for this purpose; unfortunately, reduction of the symptom onset-to-balloon time is more complex than reduction of the former.

RESUMO

The carotid artery intima-media thickness (IMT) is an established surrogate marker of vascular risk. We assessed the common femoral artery IMT and its correlation with coronary artery disease (CAD). We also assessed the influence of vascular risk factors on the femoral IMT. Patients (n = 180; mean age 60.4 ± 10.5 years) who had undergone coronary angiography due to symptoms of CAD were enrolled in this study. We found significantly higher values of femoral IMT in patients with CAD than in those without CAD (P = .0000). A strong positive correlation between femoral IMT and the severity of CAD expressed by the Gensini Score (P = .0000) was observed. There was a positive correlation between femoral IMT and levels of triglycerides (P = .017), body mass index (BMI; P = .036), male gender (P = .0000), and smoking (P = .028). There was a negative correlation between femoral IMT and the level of high-density lipoprotein-cholesterol (P = .001). Femoral IMT could be a novel cardiovascular risk marker.

RESUMO

Coronary artery aneurysms are a rare form of coronary artery disease. Due to the rarity of these aneurysms, particularly of the giant form, it is difficult to establish a standardized treatment. We report the case of a 65-year-old man who presented with symptoms of an acute coronary syndrome. A posterobasal myocardial infarction was diagnosed with a giant right coronary artery aneurysm as the underlying pathology. Two aneurysms of the left anterior descending artery were also revealed. The management strategy included ligation of the giant aneurysm coupled with distal coronary artery bypass grafting of the right coronary artery. This was complemented with a delayed percutaneous coronary intervention of the left anterior descending artery aneurysms.

RESUMO

The Republic of Croatia, with a gross domestic product per capita of US$11,554 in 2008, is an economically less-developed Western country. The goal of the present investigation was to prove that a well-organized primary percutaneous coronary intervention network in an economically less-developed country equalizes the prospects of all patients with acute ST-segment elevation myocardial infarction at a level comparable to that of more economically developed countries. We prospectively investigated 1,190 patients with acute ST-segment elevation myocardial infarction treated with primary PCI in 8 centers across Croatia (677 nontransferred and 513 transferred). The postprocedural Thrombolysis In Myocardial Infarction flow, in-hospital mortality, and incidence of major adverse cardiovascular events (ie, mortality, pectoral angina, restenosis, reinfarction, coronary artery bypass graft, and cerebrovascular accident rate) during 6 months of follow-up were compared between the nontransferred and transferred subgroups and in the subgroups of older patients, women, and those with cardiogenic shock. In all investigated patients, the average door-to-balloon time was 108 minutes, and the total ischemic time was 265 minutes. Postprocedural Thrombolysis In Myocardial Infarction 3 flow was established in 87.1% of the patients, and the in-hospital mortality rate was 4.4%. No statistically significant difference was found in the results of treatment between the transferred and nontransferred patients overall or in the subgroups of patients >75 years, women, and those with cardiogenic shock. In conclusion, the Croatian Primary Percutaneous Coronary Intervention Network has ensured treatment results of acute ST-segment elevation myocardial infarction comparable to those of randomized studies and registries of more economically developed countries.
