Mortality of patients presented with acute ST-segment elevation myocardial infarction according to the status of standard modifiable cardiovascular risk factors. Am J Med Sci 2024; 367:328-336. [PMID: 38320673 DOI: 10.1016/j.amjms.2024.01.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 01/25/2024] [Accepted: 01/30/2024] [Indexed: 02/08/2024]
Abstract
BACKGROUND Standard modifiable cardiovascular risk factors (SMuRFs) remain well-established elements of assessing cardiovascular risk scores. However, there is growing evidence that patients presented without known SMuRFs at admission demonstrate worse post-myocardial outcomes. The aim of the study was to assess the influence of the SMuRF status on short- and long-term mortality rates in patients with first-time ST-segment elevation myocardial infarction (STEMI). METHODS This observational, cross-sectional study covered 182,726 patients admitted between 2003-2020 to the CathLabs, according to data from the Polish Registry of Acute Coronary Syndrome. Both baseline characteristics and mortality (in-hospital, 30-day, and 12-month) were examined and stratified by SMuRF status. The predictors of mortality were assessed at selected time points by multivariable analysis. RESULTS The majority of STEMI patients had at least one SMuRF (88.7%), however, mortality rates of SMuRF-less individuals were greater at selected time points of the follow-up (p < 0.001), and persisted at a higher level during each year of the follow-up period compared to the SMuRF group and general population. Furthermore, the SMuRFs status constituted an independent predictor of mortality at the 30-day (OR: 1.345; 95% CI: 1.142-1.585, p < 0.001) and 12-month (OR: 1.174; 95% CI: 1.054-1.308, p < 0.001) follow-ups. CONCLUSIONS SMuRF-less individuals presented with STEMI are at an increased risk of all-cause mortality compared to those with at least one SMuRF. Consequently, further investigations regarding the recognition and treatment of risk factors, irrespective of SMuRF status, are indicated.

Radial artery spasms - angiographic morphology, risk factors and management. ADVANCES IN INTERVENTIONAL CARDIOLOGY 2024; 20:53-61. [PMID: 38616935 PMCID: PMC11008508 DOI: 10.5114/aic.2024.136936] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 03/14/2024] [Indexed: 04/16/2024] Open
Abstract
Introduction Radial artery is the preferred access for coronary interventions. However, the procedure is sometimes interrupted by a spasm which causes pain, prolongs the procedure, and can force the access crossover. Aim To observe factors contributing to a symptomatic radial artery spasm. Material and methods In this prospective study, we present results of 103 consecutive patients regarding radial artery spasm and angiographic image of the punctured artery. Angiography of the radial artery was performed in 70 (68.0%) patients. Potential risk factors for radial artery spasm were evaluated. Results The overall incidence of the radial artery spasm was high - 25 (24.3%). Signs of spasm were present in 37.1% of radial artery angiographies before the procedure and 60.1% after, however, it did not always indicate a symptomatic spasm. Risk factors related to radial artery spasm included female sex (OR = 2.94, p = 0.02), failure of the first puncture attempt (OR = 3.12, p = 0.014) and use of non-hydrophilic sheath (OR = 9.56, p = 0.036). Radial artery narrowing at the tip of the sheath was also a risk factor for spasm (p = 0.022). No spasms were observed after hydrophilic sheath application (n = 13). The administration of a radial cocktail was not observed to significantly decrease the spasm odds. Conclusions Risk factors for radial artery spasm include female sex and multiple puncture attempts. Hydrophilic sheath coating protects against radial artery spasm. Overall signs of a spasm in the angiography are common and do not imply a symptomatic spasm, which can be predicted by a tight narrowing at the tip of the sheath.

Electrocardiography versus Echocardiography in Severe Aortic Stenosis with the Consideration of Coexistent Coronary Artery Disease. J Clin Med 2024; 13:1013. [PMID: 38398326 PMCID: PMC10888567 DOI: 10.3390/jcm13041013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2023] [Revised: 02/03/2024] [Accepted: 02/07/2024] [Indexed: 02/25/2024] Open
Abstract
(1) Background: Coexistent coronary artery disease (CAD) might influence the ability of electrocardiogram (ECG) to identify echocardiographic left ventricular hypertrophy (ECHO-LVH) in patients with aortic stenosis (AS). We aimed to assess the relation between ECG-LVH (by the Sokolov-Lyon or Cornell criteria) and ECHO-LVH considering coexistent CAD. (2) Methods: We retrospectively analyzed the medical records of 74 patients (36 males) with severe AS who were hospitalized in the University Hospital in Cracow from 2021 to 2022. (3) Results: ECHO-LVH was present in 49 (66%) patients, whereas 35 (47.3%) patients had ECG-LVH. There was no difference between the rate of ECG-LVH in patients with vs. without ECHO-LVH. Single-vessel and multi-vessel CAD were diagnosed by invasive coronary angiography in 18% and 11% of patients, respectively. The sensitivity of the classical ECG-LVH criteria with regard to ECHO-LVH was low, reaching at best 41% for the Sokolov-Lyon and Cornell criteria. The results were similar and lacked a pattern when considering patients without significant stenosis, with single- and multi-vessel disease separately. Correlations between the left ventricular mass index and ECG-derived parameters were weak and present solely for the Lewis index (r = 0.31), R wave's amplitude >1.1 mV in aVL (r = 0.36), as well as the Cornell (r = 0.32) and Sokolov-Lyon (r = 0.31) voltage criteria (p < 0.01). The presence, location of stenoses, and CAD extent were not associated with the presence of either ECHO-LVH or ECG-LVH, irrespective of individual ECG-LVH criteria. (4) Conclusions: The sensitivity of classical ECG criteria for echocardiographic LVH in severe AS is low, regardless of coexistent CAD or its angiographic extent.

Is single-catheter technique for coronary angiography an optimal tool for beginners in interventional cardiology?-randomized controlled study TRACT 2: Transradial Coronary Angiography Trial 2. Cardiovasc Diagn Ther 2023; 13:1019-1029. [PMID: 38162109 PMCID: PMC10753231 DOI: 10.21037/cdt-23-212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Accepted: 09/22/2023] [Indexed: 01/03/2024]
Abstract
Background Transradial coronary angiography can be performed using a dual-catheter technique (DCT) or single-catheter technique (SCT). The current study aimed to compare DxTerity SCT Ultra and the Trapease curve SCT catheters with DCT catheters in procedures performed by young, less experienced, interventional cardiologists. Methods For this prospective, single-blinded, randomized study 107 were enrolled and assigned to 1 of 3 groups. They underwent planned coronary angiography at the Second Department of Cardiology Jagiellonian University in Kraków. In groups 1 (n=37) and 2 (n=35), DxTerity SCT Ultra catheters and the Trapease curve were used, respectively. In control group 3 (n=35), standard DCT Judkins catheters were applied. One patient was excluded from group 2, bringing the total number of cases analysed to 106. The study endpoints comprised the percentage of optimal stability, proper ostial artery engagement, a good quality angiogram, the duration of each procedure stage, the amount of contrast and the radiation dose. Results The highest percentage of optimal stability was observed in group 1 for the right coronary artery (RCA): 94%, and in group 3, for the left coronary artery (LCA): 85%. The necessity to change the catheter was most common in group 2. Group 1 was characterised by a shorter total procedural time. The contrast volume was higher in group 2, while there were no differences in radiation dose. Conclusions SCT is at least as adequate as DCT for young cardiologists. SCT was associated with lower necessity of catheter exchange during RCA visualization. The DxTerity Ultra curve catheter allows shortening the total procedure time.

Radial artery spasms impair invasive cardiological procedures' performance: a pharmacological approach to prevention and treatment. JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY : AN OFFICIAL JOURNAL OF THE POLISH PHYSIOLOGICAL SOCIETY 2023; 74.

Abstract
The radial artery (RA) access is currently the gold standard to perform cardiovascular interventions. One of the more common limitations is radial artery spasm which is an often complication interrupting the procedure. Common risk factors associated with spasm include female gender, periprocedural anxiety, multiple puncture attempts, distal radial access, diabetes, hypertension, and smoking. The mechanism of spasm is complex and includes calmodulin and rho-kinase pathways leading to the smooth muscle contraction. Proper hydration, anxiety management, and adequate local anesthesia should be applied to decrease the risk of spasms. Radial cocktail is often used to prevent spasm. Its composition differs between catheterization laboratories and the effect is attributed either to the verapamil or nitroglycerin, with contradictory results of different studies. Balbay maneuver is also an effective mean of prevention. Hydrophilic-coated devices can be used both to avoid spasms or reverse them. Radial angiography can be used to differentiate spasm from a tortuosity and choose proper method of management. Fasudil, a Rho-kinase inhibitor, has been reported as a pharmacological method to prevent spasm and reverse radial artery spasm.

Abstract
Introduction Electrocardiographic (ECG) patterns suggestive of high-risk coronary anatomy are indications for an urgent invasive approach in non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Aim To estimate the frequency of the observed phenomenon and assess the clinical characteristics of NSTE-ACS subjects associated with Wellens syndrome, the de Winter sign, or ST-segment depressions by ≥ 1 mm in ≥ 6 classic ECG leads with simultaneous ST-segment elevation in aVR and/or V1. Material and methods Out of 207 pre-screened subjects diagnosed with NSTE-ACS, 64 patients (26 women and 38 men) with complete medical records (including admission ECG and coronary angiography during the index hospitalization), and significant culprit stenosis or occlusion of the left main coronary artery (LMCA) or the proximal/middle segment of the left anterior descending artery (LAD) entered the final analysis. Clinical characteristics of patients exhibiting any of the high-risk ECG patterns was compared to their counterparts with significant lesions in LMCA or proximal/middle LAD without any of the high-risk ECG patterns. Results Among 64 patients with significant culprit lesions in LMCA or LAD, 19 (29.69%) exhibited one of the high-risk ECG patterns: Wellens syndrome (n = 10), the de Winter sign (n = 0), or multiple ST-segment depressions (n = 9). Clinical characteristics were comparable in 19 NSTE-ACS patients with the high-risk ECG patterns and their 45 counterparts. Conclusions Because ECG patterns suggestive of high-risk coronary anatomy are relatively frequent in patients with NSTE-ACS and culprit lesions in LMCA or LAD, their early recognition is of clinical importance.

Risk Factors of Suboptimal Coronary Blood Flow after a Percutaneous Coronary Intervention in Patients with Acute Anterior Wall Myocardial Infarction. J Pers Med 2023; 13:1217. [PMID: 37623467 PMCID: PMC10455189 DOI: 10.3390/jpm13081217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 06/29/2023] [Accepted: 07/29/2023] [Indexed: 08/26/2023] Open
Abstract
BACKGROUND AND AIMS Primary percutaneous coronary intervention (PCI) is regarded as the most preferred strategy in ST-segment elevation myocardial infarction (STEMI). Thrombolysis in Myocardial Infarction (TIMI) flow grade has been an important and cohesive predictor of outcomes in STEMI patients. We sought to evaluate potential variables associated with the risk of suboptimal TIMI flow after PCI in patients with anterior wall STEMI. METHODS We evaluated 107 patients admitted to our hospital between 1 January 2019 and 31 December 2021 with a diagnosis of anterior wall STEMI treated with primary PCI. RESULTS Suboptimal TIMI flow grade (≤2) after PCI occurred in 14 (13%) patients while grade 3 was found in 93 (87%) of them presenting with anterior wall STEMI. Failure to achieve optimal TIMI 3 flow grade after PCI was associated with lower TIMI grade prior to PCI (OR 0.5477, 95% CI 0.2589-0.9324, p = 0.02), greater troponin concentration before (OR 1.0001, 95% CI 1-1.0001, p = 0.0028) and after PCI (OR 1.0001, 95% CI 1-1.0001, p = 0.0452) as well as lower mean minimal systolic blood pressure (OR 0.9653, 95% CI 0.9271-0.9985, p = 0.04). CONCLUSIONS Among predictors of suboptimal TIMI flow grade after PCI, we noted lower TIMI grade flow pre-PCI, greater serum troponin concentrations in the periprocedural period and lower mean minimal systolic blood pressure.

Abstract
BACKGROUND Revascularisation strategy in patients with multi-vessel coronary disease and acute myocardial infarction (AMI) remains challenging. One of the potential treatment options is complete percutaneous revascularisation during index hospitalisation. This strategy could positively influence left ventricle ejection fraction (LVEF). AIM To investigate the long-term changes in LVEF and clinical outcome among patients with AMI after complete coronary revascularisation (CCR). METHODS Records of 171 patients with a diagnosis of AMI and multi-vessel coronary artery disease (CAD) on index angiography, in whom CCR was performed as a staged procedure during initial hospitalisation, were analysed. Clinical data were collected from in-hospital medical records and discharge letters. Cardiac ultrasound (CU), with particular assessment of LVEF, was performed one day before discharge. Follow-up (FU) CU was collected from the out-patient department at least six months ± one week after discharge. Follow-up data, including major adverse cardiac events (MACE), were collected during follow-up visits by telephone. Depending on the LVEF change during the follow-up period, patients were divided into two groups. Patients with a decrease in the LVEF (D-LVEF group) were compared with patients with no changes (preserved) or improvement regarding LVEF (P/I-LVEF). RESULTS The median duration of the follow-up was 19 months (14-24 months). The median change in LVEF during observation was -5.0p% (IQR (-7.0)-(-2.75p.%)) in the D-LVEF group and +4.0% (IQR 1.0-5.0p%) in the P/I-LVEF group. Among patients in the P/I-LVEF group, there was a sub-group of patients with no change in LVEF (28 patients), and one demonstrating improvement in LVEF (104 patients). In the subgroup of patients with improved LVEF, the median change in LVEF was 4.5p% (IQR 2-6.25p%). Among patients with decreasing LVEF, there was a significantly higher risk of MACE (15 vs. 2.3%, p = 0.031), especially non-fatal AMI (10 vs. 0%, p = 0.017). We found the following among predictors concerning increased risk of MACE occurrence: urgent PCI (p = 0.004), hospitalisations regardless of cause (p = 0.028), EF worsening (p = 0.025), fasting glucose serum concentration (p = 0.024) and fasting triglyceride serum concentration (p = 0.027). CONCLUSIONS Complete revascularisation (CR) at baseline (one stage) in patients with AMI and multi-vessel disease is associated with LVEF improvement and MACE rate reduction. Patients with worse LVEF have poor clinical outcome and a higher rate of MACE.

Abstract
Introduction: Optical coherence tomography (OCT) intravascular imaging including the latest version Ultreon™ 1.0 Software (Abbott Vascular, Santa Clara, CA, USA), not only improve patients prognosis, but also facilitates improved percutaneous coronary intervention (PCI). Objectives: The aim of the study was to compare procedure related decision making, procedural indices, clinical outcomes according to the extent of stent expansion and assess risk factors of underexpansion in patients treated with PCI using OCT. Methods: The study comprised 100 patients, which were divided in groups according to the extent of stent expansion: <90 (29 patients) and ≥90% (71 patients). Comparison of OCT parameters, selected clinical and procedural characteristics was performed between groups. We assessed clinical outcomes during the follow-up: major adverse cardiovascular events and risk factors of stent underexpansion. Results: Patients from the stent underexpansion group were treated more often in the past with percutaneous peripheral interventions (p=0.02), no other significant differences being noted in general characteristics, procedural characteristics or clinical outcomes comparing both groups. Significant predictors of stent underexpansion assessed by simple linear univariable analysis included: hypercholesterolemia, obstructive bronchial diseases and treatment with inhalators, family history of cardiovascular disease, PCI of other than the left main coronary artery, stent and drug-eluting stent implantation, PCI without drug-eluting balloon, paclitaxel antimitotic agent, greater maximal stent diameter and lower mean Euroscore II value. Univariable logistic regression analysis revealed a correlation between stent underexpansion and greater creatinine serum concentration before [OR: 0.97, 95%CI: 0.95-0.99, p=0.01] and after PCI [OR: 0.98, 95%CI: 0.96-0.99, p=0.02]. Conclusions: Based on the presented analysis, the degree of stent expansion is not related to the selected procedural, OCT imaging indices and clinical outcomes. Logistic regression analysis confirmed such a relationship for creatinine level.

Annual operator volume among patients treated using percutaneous coronary interventions with rotational atherectomy and procedural outcomes: Analysis based on a large national registry. Catheter Cardiovasc Interv 2022; 99:1723-1732. [PMID: 35318789 DOI: 10.1002/ccd.30155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 01/31/2022] [Accepted: 03/05/2022] [Indexed: 11/08/2022]
Abstract
BACKGROUND Low operator and institutional volume are associated with poorer procedural and long-term clinical outcomes in the general population of patients treated with percutaneous coronary interventions (PCI). AIM To assess the relationship between operator experience and procedural outcomes of patients treated with PCI and rotational atherectomy (RA). METHODS Data for conducting the current analysis were obtained from the national registry of percutaneous coronary interventions (ORPKI) maintained in cooperation with the Association of Cardiovascular Interventions (AISN) of the Polish Cardiac Society. The study covers data from January 2014 to December 2020. RESULTS During the investigated period, there were 162 active CathLabs, at which 747,033 PCI procedures were performed by 851 operators (377 RA operators [44.3%]). Of those, 5188 were PCI with RA procedures; average 30 ± 61 per site/7 years (Me: 3; Q1-Q3: 0-31); 6 ± 18 per operator/7 years (Me: 0; Q1-Q3: 0-3). Considering the number of RA procedures annually performed by individual operators during the analyzed 7 years, the first quartile totaled (Q1: < =2.57), the second (Q2: < =5.57), and the third (Q3: < =11.57), while the fourth quartile was (Q4: > 11.57). The maximum number of procedures was 39.86 annually per operator. We demonstrated, through a nonlinear relationship with annualized operator volume and risk-adjusted, that operators performing more PCI with RA per year (fourth quartile) have a lower number of the overall periprocedural complications (p = 0.019). CONCLUSIONS High-volume RA operators are related to lower overall periprocedural complication occurrence in patients treated with RA in comparison to low-volume operators.

Abstract
BACKGROUND Patients undergoing percutaneous coronary interventions (PCI) with rotational atherectomy (RA) have massively calcified coronary arteries and differ according to sex. AIMS To assess trends in sex-related percentage shares in following years, to compare demographic characteristics between men and women, and to identify factors associated with the risk of periprocedural complications and death. METHODS Based on the Polish National Registry of Percutaneous Coronary Interventions (ORPKI), we analyzed 751 113 patients treated with PCI between 2014 and 2020. We extracted 5 177 (0.7%) patients treated with RA, 3 552 of them (68.6%) being men. To determine risk factors of periprocedural complications and death, multivariable analysis was performed. RESULTS The proportion of PCIs involving RA increase between 2014 and 2020 (P < 0.001). Almost twice as many RA procedures pertain to men (68.55%), while the percentage share did not change in following years. Data are reported as mean (standard deviation). The female patients were older (75.2 [8.3] vs 70.5 [9.2] years; P < 0.001). When considering periprocedural complications, their overall rate (3.45% vs 2.31%; P = 0.01) and death rate (0.68% vs 0.17%; P = 0.006) were greater among women. Also, via multivariable analysis, female sex was found to be a risk factor of greater periprocedural mortality (P = 0.02) and overall complication rate (P = 0.007). CONCLUSIONS The majority of patients treated with RA are men and sex-related distribution was stable during the analyzed period of time. Female sex is a risk factor of greater periprocedural complications and mortality in patients treated with RA.

[PMID: 34200250 PMCID: PMC8201254 DOI: 10.3390/ijerph18116151] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 05/26/2021] [Accepted: 06/05/2021] [Indexed: 11/16/2022]
Abstract
The radial approach (RA) is the most common in invasive cardiology, but depending on the clinical situation, the femoral approach (FA) and brachial approach (BA) are also used. The BA is associated with the highest odds of complications so it is used mainly if a first-choice approach fails. The aim of the study was to assess clinical outcomes after invasive cardiology procedures stratified by the use of the RA, FA, and BA, with a focus on access site-related complications, quality of life (QoL), and patients' perspective. A total of 250 procedures (RA: 98; FA: 99; BA: 53) performed between 2013 and 2020 were retrospectively analyzed. Puncture site-related complications, vascular events, patient preferences, and QoL were assessed by the analysis of medical records and telephone follow-up using a proprietary questionnaire and the modified EQ-5D-3L questionnaire. Patients from the RA group received the smallest volume of contrast during a percutaneous coronary interventions (PCI) procedure (RA vs. FA vs. BA: 180 (150-240) mL vs. 200 (180-270) mL vs. 190 (100-200) mL, p = 0.045). The access site was changed most frequently in the procedures initiated from the RA (p < 0.04). Overall puncture site-related complications, especially local hematomas, occurred most commonly in the BA group (7.1, 14.1, and 24.5% for RA, FA, and BA, respectively, p = 0.01). During the index procedure, the access site was changed most frequently in procedures initiated from the RA (19.7, 8.5 and 0%, p = 0.04). The RA was indicated as an approach preferred by the patient for a hypothetical next procedure (87.9, 55.4, and 70.0% for subjects preferring the same approach out of patients who underwent a procedure by the RA, FA, and BA, respectively, p < 0.001). For the RA and FA, the prevalence of moderate or extreme access site-related problems in self-care decreased significantly (RA: p < 0.01, FA: p < 0.05) within 1 month after the index procedure (RA: 18.1, 4.2, and 1.4%; FA: 20.7, 11.1, and 9.6% periprocedurally, after 1 and 6 months, respectively). In contrast, for the BA these percentages were higher and a significant improvement (p < 0.05) was delayed until 6 months (54.6, 36.4, and 18.2% periprocedurally, after 1 and 6 months, respectively). In conclusion, compared to the BA and FA, the RA appears to be not only the safest, mainly due to the lowest risk of puncture site-related complications after coronary procedures but also represents a preferable approach from the patient's perspective. Although overall post-procedural QoL outcomes did not differ significantly according to the access site, nevertheless, the BA was associated with more frequent self-care problems whose improvement was delayed until more than one month after the index procedure.

Comparison of the Characteristics of Coronary Interventions Performed During Day and Night Shifts in Patients with Acute Myocardial Infarction. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17155378. [PMID: 32722586 PMCID: PMC7432738 DOI: 10.3390/ijerph17155378] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 07/20/2020] [Accepted: 07/22/2020] [Indexed: 11/16/2022]
Abstract
Therapeutic percutaneous coronary intervention (PCI) is the treatment of choice in acute myocardial infarction (AMI). If optimally performed, PCI reduces myocardial injury and improves the likelihood of a positive clinical outcome. Therefore, the equal quality of PCI throughout both day and night shifts is of paramount importance. Our aim was to compare urgent diagnostic and therapeutic coronary interventions performed during day and night shifts. We retrospectively analyzed the medical records of 144 patients who underwent coronary angiography for AMI over six months in a tertiary referral center working in 24/7 mode. The patients' characteristics, procedural data and the operator's experience in interventional cardiology were compared according to the time of intervention during a day shift (8 a.m. until 8 p.m., group A, n = 106) and night shift (from 8 p.m. until 8 a.m. next day, group B, n = 36). The baseline characteristics of the subjects of groups A and B were similar, except for a higher proportion of AMI without persistent ST-segment elevation (NSTEMI) in patients who underwent coronary angiography during regular working hours compared to off-hours (58% vs. 34%, p < 0.05). The average time of diagnostic coronary angiography was longer by about 5 min during the day shift (28.5 ± 12.2 vs. 23.8 ± 8.9 min, p < 0.05), while other procedural data, including the arterial access route, the number of catheters needed and the contrast-medium volume, were similar. The use of additional diagnostic tools for coronary lesion assessment (intracoronary ultrasound or fractional flow reserve measurement) was almost twice as frequent during regular working hours (15% vs. 8%). Urgent therapeutic PCI on the culprit artery was performed in 79% and 89% of group A and B patients, respectively. The groups did not differ in procedural characteristics regarding the total interventional session, including both diagnostic angiography and therapeutic PCI, such as total procedure duration, fluoroscopy time, radiation dose, stenting technique and total stent length. Coronary thrombectomy or rotational atherectomy were more frequently used in group A (27% vs. 15%, p = 0.16). The percentage of doctors with the least experience in interventional cardiology was, albeit insignificantly, lower during day shifts (31% vs. 42%). In conclusion, the majority of clinical and periprocedural characteristics appeared to be independent of intervention time, except for a longer duration of diagnostic coronary angiography during daytime. This finding could probably result from a higher proportion of NSTEMI patients frequently requiring additional angiographic projections and special techniques to properly identify the infarct-related artery during the day shift. Whether a tendency of less frequent use of additional tools at off-hours may also be due to a lower percentage of NSTEMI interventions at night, or whether this can be linked to lower availability of experienced operators, remains to be validated in a large study. The latter possibility, if confirmed, might encourage public health authorities and healthcare organizers to improve off-hours cathlab staffing with experienced interventionalists. Finally, additional obligatory training in special diagnostic and therapeutic invasive techniques might be advisable for the least experienced operators scheduled to work night shifts.

Low Ejection Fraction Predisposes to Contrast-Induced Nephropathy after the Second Step of Staged Coronary Revascularization for Acute Myocardial Infarction: A Retrospective Observational Study. J Clin Med 2020; 9:jcm9061812. [PMID: 32532038 PMCID: PMC7356857 DOI: 10.3390/jcm9061812] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 05/30/2020] [Accepted: 06/07/2020] [Indexed: 12/11/2022] Open
Abstract
Patients who develop contrast-induced nephropathy (CIN) are at an increased short-term and long-term risk of adverse cardiovascular (CV) events. Our aim was to search for patient characteristics associated with changes in serum creatinine and CIN incidence after each step of two-stage coronary revascularization in patients with acute myocardial infarction (AMI) and multivessel coronary artery disease undergoing staged coronary angioplasty during hospitalization for AMI. We retrospectively analyzed medical records of 138 patients with acute myocardial infarction without hemodynamic instability, in whom two-stage coronary angioplasty was performed during the initial hospital stay. In-hospital serum creatinine levels were recorded before the 1st intervention (at admission), within 72 h after the 1st intervention (before the 2nd intervention), and within 72 h after the 2nd intervention. The incidence of CIN was 2% after the 1st intervention (i.e., primary angioplasty) and 8% after the 2nd intervention. Patients with significant left ventricular systolic dysfunction after the 1st intervention (ejection fraction (EF) ≤35%) exhibited higher relative rises in creatinine levels after the 2nd intervention (18 ± 29% vs. 2 ± 16% for EF ≤35% and >35%, respectively, p = 0.03), while respective creatinine changes after the 1st revascularization procedure were comparable (−1 ± 14% vs. 2 ± 13%, p = 0.4). CIN after the 2nd intervention was over five-fold more frequent in subjects with low EF (28% vs. 5%, p = 0.007). The association between low EF and CIN incidence or relative creatinine changes after the 2nd intervention was maintained upon adjustment for baseline renal function, major CV risk factors, and the use of renin-angiotensin axis antagonists prior to admission. In conclusion, low EF predisposes to CIN after second contrast exposure in patients undergoing two-stage coronary angioplasty during the initial hospitalization for AMI. Our findings suggest a need of extended preventive measures against CIN or even postponement of second coronary intervention in patients with significant left ventricular dysfunction scheduled for the second step of staged angioplasty.

Adv Med Sci 2020; 65:197-201. [PMID: 32014808 DOI: 10.1016/j.advms.2020.01.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 09/10/2019] [Accepted: 01/21/2020] [Indexed: 11/19/2022]
Abstract
PURPOSE We sought to investigate gender-related differences in clinical outcomes after peripheral vascular interventions (PVIs) from retrograde access in patients with chronic total occlusions (CTOs) of the infrainguinal arteries. PATIENTS AND METHODS A total of 939 consecutive patients undergoing PVI were enrolled in the study. Patients with peripheral artery diseases (PAD) and CTOs were treated with PVI from retrograde access according to the local protocol. The participants were divided according to gender. Retrograde access included distal puncturing to reach the CTO. The mean follow-up lasted 1,144.9 ± 664.3 days. Baseline characteristics, procedural and long-term outcomes were compared according to gender. RESULTS Women represented 37.4% of the study population, and more frequently suffered from hypertension (92% vs. 86%, p = 0.001) and diabetes (54% vs. 46%, p = 0.02). Males more often presented with chronic obstructive pulmonary disease (14.8% vs. 6.8%, p = 0.0003), coronary artery disease (45.4% vs. 32.7%, p = 0.0001), smoking (60.4% vs. 45%, p = 0.007) and prior PVI (25% vs. 17%, p = 0.005). The Kaplan-Meier survival curves at 5 years did not reveal gender-related differences in mortality (p = 0.8), whereas men were at a significantly higher risk of re-PVI during the follow-up period (p = 0.047). Male gender was an independent predictor of re-PVI (Hazard ratio: 1.276; 95% confidence interval: 1.015-1.614, p = 0.03). CONCLUSION Males are at increased risk of re-PVI compared to females with PAD and CTOs of infrainguinal arteries treated with PVI from retrograde access.

Abstract
Background In this trial, our objective was to evaluate the relationship between long-term clinical outcomes in patients with peripheral arterial disease (PAD) treated with retrograde endovascular recanalization (ER) of chronic total occlusions (CTOs) regarding the infra-inguinal lower limb arteries and chronic obstructive pulmonary disease (COPD). Methods A total of 834 consecutive subjects were enrolled in the study. The mean age was 67.8±10.6 years (62.6% males). COPD was diagnosed in 98 patients (11.7%). The infra-inguinal location included the deep, superficial and common femoral artery, popliteal artery or below the knee arteries. During follow-up, we evaluated major adverse cardiac and cerebrovascular events (MACCE) and major adverse limb events (MALE). MACCE was considered as death, stroke/transient ischemic attack, myocardial infarction, percutaneous coronary intervention or coronary artery bypass grafting operation, while MALE regarded amputation, target lesion re-intervention, target vessel re-intervention and surgical action. Results The mean follow-up was 1,144.9±664.3 days and the interquartile range was 1,110.5 (504.5–1,734.7). Data were collected between 2006 and 2016. We noticed significant differences in death rates among the COPD and non-COPD groups. The cumulative number of events (deaths) was 12.2%, 17.3%, 18.4%, 22.4%, 23.5%, 23.5% and 23.5% in the COPD group and 6.1%, 7.5%, 10.5%, 11.3%, 11.4% 11.5% and 11.5% in the non-COPD group after 1, 2, 3, 4, 5, 6 and 7 years of follow-up, and was notably greater for COPD (P=0.0007). Conclusions Patients with COPD and PAD treated with the ER and retrograde approach due to CTOs are related to higher mortality than non-COPD patients.

Abstract
Decreased plasma levels of microRNA-223 (miR-223), predominantly of platelet origin, were proposed as a surrogate marker of efficacy of antiplatelet therapy. However, higher on-treatment platelet reactivity was associated with lower plasma miR-223 in patients with coronary artery disease (CAD) on dual antiplatelet therapy (DAPT) including clopidogrel and aspirin. Our aim was to compare plasma miR-223 and platelet reactivity in CAD patients on DAPT with newer P2Y12 antagonists vs. clopidogrel. We studied 21 men with CAD admitted to our centre owing to a non-ST-elevation acute coronary syndrome, and with an uncomplicated hospital course. From the day of admission, the patients were receiving either clopidogrel (n = 11) or prasugrel/ticagrelor (n = 10) in addition to aspirin. Before discharge, miR-223 expression in plasma was estimated by quantitative polymerase chain reaction using the comparative Ct method relative to miR-16 as an endogenous control. Multiple electrode aggregometry was used to assess platelet aggregation in response to adenosine diphosphate (ADP). ADP-induced platelet reactivity was decreased in the patients treated with prasugrel or ticagrelor compared with those on clopidogrel (mean ± SD: 139 ± 71 vs. 313 ± 162 arbitrary units [AU]*min, p = 0.006), due to a more potent antiplatelet activity of the novel P2Y12 antagonists. Consequently, six out of seven patients in the lower tertile of the ADP-induced platelet aggregation were treated with the newer P2Y12 blockers, whereas six out of seven patients in the upper tertile were on clopidogrel. Plasma miR-223 was elevated with decreasing platelet reactivity (Spearman's rho = -0.52; p = 0.015 for trend), being significantly higher in the lower tertile of the ADP-induced platelet aggregation (median [range]: 1.06 [0.25-2.31]) vs. the upper tertile (0.20 [0.13-2.30]) (p = 0.04). In conclusion, our preliminary results argue against the notion of low plasma miR-223 as a marker of platelet responsiveness to DAPT. On the contrary, more potent platelet inhibition associated mainly with newer P2Y12 antagonists appears to coincide with higher miR-223 relative to the subjects with attenuated responsiveness to DAPT.

Abstract
Among heterogeneous groups of patients admitted to the catheterisation laboratory due to non-ST elevation myocardial infarction (NSTEMI), there are increasing numbers with coexisting valvular heart diseases. A 66-year-old man was transferred to our centre with a diagnosis of NSTEMI. Immediate echocardiogram was performed in which a left ventricular ejection fraction (LVEF) of 50% with regional wall motion abnormalities and aortic stenosis was present. Urgent coronary angiography showed near total occlusion (99% stenosis) in the mid-segment of the left circumflex artery. During the same procedure, we performed percutaneous coronary intervention of the infarct-related artery (IRA) with direct bare metal stent implantation. An optimal distal flow in the IRA (TIMI 3) was achieved. An echocardiography assessment performed the next day revealed an improvement of the LVEF (from 50% to 61%) and severe aortic stenosis with maximum transaortic pressure gradient of 123 mm Hg (mean 69.6 mm Hg) and aortic valve area 0.8 cm2. Adhering to the Heart Team's recommendation, surgical aortic valve replacement (AVR) was planned for eight weeks after hospital discharge. We considered the possibility of changing the qualification of urgent AVR, so bare metal stent implantation seems to be the optimal treatment strategy for this patient.

Abstract
We present the case of a 70-year-old female patient diagnosed with unstable angina, who was qualified to coronarography in a peripheral interventional cardiology department. Critical stenosis of right posterior descending artery was found. During percutaneous coronary intervention, after-stent balloon catheter interrupted and was left partially in the right coronary artery sticking out of the aortic arch. In a second attempt at removal, using an Amplatz GooseNeck snare, operators managed to take the broken balloon out of the intravascular space.

Abstract
Congenital abnormalities of the coronary arteries are found in 0.6-1.5% of patients in coronary angiographies and most of them are benign. Their presence may prolong the time of the examination which is important especially in patients with acute coronary syndromes (ACS). The incidence of coronary artery anomaly with critical stenosis in the anomalous vessel may impose technical problems during percutaneous coronary intervention (PCI). We report the case of a patient with one of the most common coronary anomaly and ACS treated with multivessel PCI.

Abstract
The development of cath-lab network providing interventions in acute coronary syndromes led not only to significant reduction of major adverse cardiac events, but also reduced incidence of myocardial infarction (MI) mechanical complications in acute phase. In the pre-interventional era one of the most common complication of ST elevation MI was left ventricular free wall rupture (LVFWR). Currently it became a rare complication, but despite the advances in cardiosurgical treatment is still associated with high mortality rate. We report the case of a 75-year-old woman with inferior wall MI and LVFWR of atypical presentation.

Abstract
BACKGROUND coronary artery disease (CAD) is often accompanied by peripheral artery disease. There are patients who are disqualified from surgical approach in the treatment of limb ischaemia due to many comorbidities including severe CAD. AIM to examine whether multilevel intervention (peripheral and coronary) in patients with multi-vessel CAD (MVD) carries a higher in-hospital and long-term risk in comparison to patients with a single vessel disease (SVD). METHODS data on consecutive patients with peripheral artery disease and CAD (acute coronary syndrome) were gathered in our department from January 2003 till June 2009. All patients included in the study had peripheral and coronary angioplasty performed during the same index hospital stay. Patients were divided into two groups: those with SVD and those with MVD in coronary angiography. RESULTS there were 116 patients included in the study - 56 patients in the SVD group and 60 patients in the MVD group. The frequency of major adverse cerebrovascular and cardiac events during long-term follow up tended to be higher in patients with MVD, however the difference did not reach statistical significance (MVD vs SVD: 13.3% vs 3.6%, p = 0.061). There were significantly more major adverse peripheral events such as repeat percutaneous transluminal angioplasty, stroke/transient ischaemic attack and lower limb amputation in the MVD group than in the SVD patients (20% vs 1.8%, p = 0.002). CONCLUSIONS percutaneous angioplasty of lower limb arteries in patients with MVD seems to be an effective and relatively safe method of treatment of patients with disseminated atherosclerosis and an alternative to surgical treatment.

Abstract
We present a case of a 47-year-old man with ST-segment-elevation myocardial infarction (STEMI), successfully treated with bare metal stent implantation. After 20 months the patient was readmitted with another episode of STEMI due to in-stent thrombosis following voluntary withdrawal of anti-platelet therapy. The implications of late stent thrombosis after bare metal stent implantation are discussed. We compare this phenomenon with thrombosis after implantation of drug-eluting stents. Various aspects and potential causes of late stent thrombosis are reviewed, especially the issues pertaining the use of anti-platelet therapy and duration of this therapy.

Abstract
BACKGROUND The coexistence of peripheral artery disease (PAD) and multilevel atherosclerosis increases death and stroke rates in patients with coronary artery disease (CAD). Due to many comorbidities these patients are often treated conservatively without revascularisation. AIM To investigate whether complex percutaneous cardiovascular interventions for CAD and PAD may improve prognosis and long-term outcome in this group of patients. METHODS We studied consecutive patients treated for symptomatic CAD who also had chronic PAD. The primary cause of hospital admission for all our patients was non-ST elevation acute coronary syndrome (NSTE ACS). All percutaneous peripheral interventions were performed during one hospital stay (index hospitalisation). Major adverse cardio- and cerebrovascular events (MACCE) during follow-up were defined as follows: death (cardiac and non-cardiac), myocardial infarction (MI), urgent revascularisation (surgical or repeat PCI, peripheral percutaneous intervention), stroke/TIA or amputation. RESULTS We performed 109 interventions in 78 consecutive patients with chronic peripheral artery stenoses and occlusions. The average age was 61.5+/-8.6 years and the majority were males (80%). Preinterventional angiography showed occlusions that involved the common iliac artery in 28 (36%) patients, the external iliac artery in 16 (21%) patients, internal iliac artery in 2 (3%) patients, and superficial femoral artery in 63 (81%) patients. Stenting was performed in half of the patients with a mean stent length of 69.6+/-50.3 mm. An average number of 1.24+/-0.55 stents was used for each lesion. During a mean follow-up of 18 months (range 4 to 42), there were 4 deaths, 3 MIs, 13 repeated percutaneous peripheral interventions due to restenosis in previously treated peripheral lesions, two urgent coronary interventions, two ischaemic strokes, two TIAs and one amputation. The combined follow--up MACCE end-point occurred in 32% of patients. CONCLUSIONS Patients with concomitant CAD and PAD could safely undergo percutaneous cardiovascular and peripheral interventions. Multilevel intervention is associated with a promising long-term follow-up.

Abstract
BACKGROUND Non ST-segment elevation acute coronary syndromes (NSTE ACS) are the most frequent cause of admission to intensive care units. Early risk assessment and implementation of optimal treatment are of special importance in these patients. Previous studies have demonstrated that renal insufficiency is an independent risk factor in patients with cardiovascular disease. AIM To assess the effects of renal function on the course of treatment and prognosis in patients with NSTE ACS admitted to hospitals without on-site invasive facilities but with a possibility of immediate transfer to a reference centre with a catheterisation laboratory. METHODS Twenty-nine community hospitals without on-site invasive facilities participated in the Krakow Registry of Acute Coronary Syndromes - a prospective, multicentre, web-based, observational registry. Renal insufficiency (RI) was defined as creatinine clearance (CrCl) <60 ml/min. RESULTS NSTE ACS was diagnosed in 1396 patients. Renal insufficiency was diagnosed in 34% of all patients. Only 17% of them had been diagnosed with RI prior to admission. Transfer for invasive treatment was undertaken in 10% of RI patients as compared to 16% of patients with CrCl >60 ml/min (NS). In-hospital mortality among patients remaining on conservative treatment in community hospitals was significantly higher among RI patients (4.0 vs. 0.6%; p <0.001). Thienopyridines were less frequently used in RI patients (46 vs. 54%; p <0.05). In-hospital mortality among RI patients remaining in community hospitals and treated conservatively was higher than among non-RI patients in each TIMI risk score group: 7.3 vs. 2.4% (p <0.05) in the high risk group, 4.1 vs. 1.4% (NS) in the moderate and 3.6 vs. 0% (p <0.001) in the low risk group. Multivariate logistic regression analysis identified reduced creatinine clearance and a history of heart failure as independent factors influencing mortality. CONCLUSIONS Renal insufficiency was present in one-third of NSTE ACS patients. Patients with renal insufficiency had worse clinical risk profile and received less aggressive treatment. Patients with NSTE ACS and renal insufficiency treated conservatively had higher in-hospital mortality. Renal insufficiency modifies mortality irrespective of the TIMI risk score. Creatinine clearance should be considered in modification of the TIMI risk score scale.

Abstract
We hereby report the first--to the best of our knowledge--case of primary lipoma of the aortic valve. The tumor has been diagnosed by echocardiography supported by magnetic resonance imaging in a 63-year-old man with acute inferior ST-elevation myocardial infarction (STEMI) and one-vessel coronary artery disease. Five weeks from the onset of STEMI, direct implantation of a bare metal stent into the right coronary artery was successfully undertaken and 6 weeks later aortic valve with an encapsulated mass was excised with subsequent artificial valve implantation. Histological examination revealed typical features of lipoma. Three months after the operation the patient was asymptomatic and exhibited a good function of the artificial valve.

Abstract
INTRODUCTION Statins given after acute coronary syndrome without ST elevation (NSTE-ACS) reduce the incidence of major adverse cardiac events (MACE) in long-term follow-up. AIM To evaluate the effects of high-dose statin administered in patients with NSTE ACS and increased CRP level prior to percutaneous coronary intervention (PCI) on the incidence of MACE in long-term follow-up. METHODS The study involved 140 consecutive patients with NSTE ACS and increased CRP level at baseline. Patients from group A (n=54) did not receive statin before PCI, whereas subjects in group B (n=86) were given 80 mg of atorvastatin. Patients in both groups received typical cardiological therapy including aspirin, thienopyridine and low molecular weight heparin. After PCI all patients received 40 mg of atorvastatin. Incidence of MACE (death, myocardial infarction (MI), re-PCI) during long-term followup was evaluated in both groups. RESULTS Study groups did not differ with respect to demographic parameters and rate of ischaemic heart disease risk factors. Also, no differences occurred regarding CRP level (group A vs. B: hsCRP 10.8+/-1.8 mg/l vs. 8.2+/-2.8 mg/l; p=NS) and TIMI Risk Score (group A vs. B: 4.3+/-0.71 vs. 4.37+/-0.79; p=NS). During long-term follow-up the incidence of MI (9.25% vs. 1.2%, p=0.03), composite endpoint: death + MI (14.8% vs. 2.32%, p=0.013) and death + MI + re PCI (25.9% vs. 8.1%, p=0.006) was significantly higher in group A than group B. CONCLUSIONS Administration of high-dose statin in NSTE ACS patients before PCI was associated with significant reduction of MACE in long-term follow-up. This effect was observed despite the same therapy given after PCI.

Abstract
INTRODUCTION Available data indicate that stenting of the left main coronary artery (LMN) is safe and effective. Restenosis remains the main factor limiting the effectiveness of percutaneous coronary intervention (PCI). AIM To evaluate immediate and long-term results of treatment of patients with LMN disease and low preoperative risk of coronary artery bypass grafting. METHODS Coronary stents were implanted into LMN in 64 patients. The following strategy was applied: drug eluting stent (DES) for LMN diameter < or =3.5 mm (28 subjects) and bare metal stent (BMS) for LMN diameter >3.5 mm (36 subjects). Patients enrolled in the study underwent clinical evaluation and coronary angiography. Immediate effect of the procedure and main adverse cardiac events were assessed: death, myocardial infarction and additional target lesion or non-target lesion revascularization. RESULTS Angiographic and clinical effectiveness of the interventions was 100%. Full revascularisation of ischaemic regions of the myocardium was performed. Mean clinical follow-up period was 9.4+/-4.0 months. Neither death nor myocardial infarction occurred. Additional PCIs were performed in 11 (17.2%) patients; however, target vessel revascularisation (TVR) rate within LMN was 9.4% (i.e. 6 subjects with BMS), and non-TVR rate was 7.8% (5 subjects). CONCLUSIONS LMN stenting is associated with high effectiveness of PCI in patients with low operative risk. Long-term follow-up revealed low incidence of major adverse cardiac events. Strategy of selective use of DESs in the study group produced good clinical outcome. Multivessel disease with LMN stenosis was associated with high rate of additional revascularisation of other vessels. Further improvement of treatment results may be obtained by more common use of DES for multivessel disease and LMN diameters larger than 4.0 mm.

Abstract
OBJECTIVE Safety and feasibility evaluation of intracoronary temperature measurements in patients with acute coronary syndromes (ACS) using a catheter based thermography system. METHODS AND RESULTS Thermography was performed in 40 patients with ACS. A 3.5-F thermography catheter containing 5 thermocouples measuring vessel wall temperature, and 1 thermocouple measuring blood temperature (accuracy 0.05 degrees C) was used. Gradient (deltaTmax) between blood temperature (T(bl)) and the maximum wall temperature during pullback was measured. The device showed satisfactory safety in ACS. Only in 16 patients (40%) deltaTmax was > or = 0.1 degrees C. In 23 patients (57.5%) the highest deltaTmax was found in the culprit segment. DeltaTmax between culprit and adjacent non-culprit segments was observed in patients with transient blood flow interruption during thermography (0.11+/-0.03 versus 0.08+/-0.01; P=0.04), in contrast to patients with preserved flow (0.07+/-0.03 versus 0.06+/-0.02; P=0.058). CONCLUSIONS The novel, technically sophisticated intracoronary thermography proved its safety and feasibility. However, we were not able to convincingly and consistently differentiate between different lesions at risk, despite a selection of lesions that should appear most distinct to differentiate. A systematic interruption of flow may be necessary to achieve diagnostic results consistently, although such requirement may unfavorably change the risk-to-benefit ratio of this developing technology.

Abstract
INTRODUCTION Borderline coronary lesions are responsible for about 80% of acute coronary syndromes (ACS). Statins have been found to improve long-term prognosis in patients with coronary artery disease due to plaque stabilization. There are no reports on the frequency of new events caused by progression of borderline lesions in patients with (ACS). Percutaneous coronary intervention (PCI) as a method of mechanical stabilization of borderline coronary lesions could be an alternative to pharmacological approach. AIM To compare the efficacy of pharmacological and mechanical stabilization of borderline plaques (DS = 40-60%) in patients with ACS. PATIENTS AND METHODS Patients with ACS and angiographically documented borderline lesions, related to the ACS or located in other coronary arteries were enrolled. Patients were randomized to receive pharmacotherapy without intervention or to undergo PCI. The primary end-point was rate of target lesion revascularization with PCI or coronary bypass grafting (CABG) caused by progression of coronary stenosis or in-stent restenosis/thrombosis. The secondary endpoint was incidence of major adverse cardiac events (MACE) at long-term follow-up (death, ST segment elevation acute coronary syndrome--STEACS and non-ST segment elevation acute coronary syndrome-- NSTEACS). RESULTS Pharmacological stabilization was used in 50 patients, mean age 56.7 +/- 9.14 years, whereas 44 patients, mean age 57.2 +/- 10.4 years, underwent plaque stabilization with PCI. At follow-up (mean 521 days) target lesion revascularization was performed in 3 patients, previously receiving pharmacotherapy, due to progression of coronary stenosis, and in 3 patients, after prior PCI, due to in-stent restenosis (7% vs. 8%, p = NS). The rate of MACE in both groups was also similar (6% vs. 5%, p = NS). CONCLUSION There were no differences between mechanical and pharmacological stabilization of borderline coronary lesions in patients with acute coronary syndromes.

Abstract
BACKGROUND Percutaneous coronary interventions (PCI) in acute myocardial infarction with ST segment elevation (STEMI) are associated with distal coronary embolisation. It may be speculated that percutaneous thrombectomy preceding stent implantation may prevent coronary microcirculation from embolisation. AIM To assess safety and efficacy of percutaneous thrombectomy in patients with STEMI. METHODS Seventy two patients with STEMI were randomised to PCI with stent implantation alone (n=32) or percutaneous thrombectomy with the RESCUE system, followed by stent implantation (n=40). Coronary flow in infarct related artery before and after the procedure was assessed using TIMI scale and corrected TIMI frame count - cTFC. Myocardial blood flow was measured using TIMI myocardial perfusion grade - tMPG. The degree of ST segment resolution 60 min after PCI was also assessed. Left ventricular ejection fraction (LVEF) was measured in hospital and three months later. RESULTS The two groups did not differ with respect to the time from the onset of symptoms to the procedure (236+/-162 min vs 258+/-198 min, NS) or the baseline TIMI, cTFC and tMPG values. An effective thrombectomy procedure was performed in 35 (87%) patients from group B. After the procedure, the number of patients with TIMI 3 grade as well as cTFC values and the proportion of patients with tMPG 3 were similar in both groups (86% vs 85%, NS; 19 vs 21, NS; and 38% vs 54%, NS). The sum of ST segment elevations after the procedure was significantly greater in patients who underwent PCI only compared with patients who had thrombectomy and PCI (6.8+/-5.2 mm vs 3.6+/-2.9 mm, p=0.004). Complete normalisation of ST segment was achieved in 68% of patients treated with thrombectomy and PCI compared with 25% of patients who had PCI only (p=0.005). CK-MB peak values occurred significantly earlier in patients treated with thrombectomy (92.1% vs 66.7% up to 360 min, p=0.01). After 3 months of follow-up, LVEF tended to be greater in patients treated with thrombectomy and PCI than in those who underwent PCI only (55.3+/-14.7% vs 60.3+/-9.2%, NS). CONCLUSIONS Thrombectomy with the RESCUE system in patients with STEMI is safe and effectively restores patency of infarct related artery. Thrombectomy better improves myocardial perfusion than standard PCI.

Abstract
A case of a 70-year-old female who underwent CABG (four grafts) 12 years earlier, is presented. Following surgery, the patient suffered from two reinfarctions. Coronary angiography revealed total occlusion of the graft implanted to the right coronary artery which was treated by coronary angioplasty. Because of restenosis, the patient underwent successful intracoronary brachytherapy.

Abstract
BACKGROUND Intarcoronary brachytherapy with radioactive source is the method of choice to treat in stent restenosis. Currently, we have data available from randomized clinical trials, yet every day practice and routine results of barchytherapy are not completely defined. METHODS We studied 50 patients treated due to in stent restenosis. Procedures were performed by means of beta radiation, and the delivered dose was equal to 2000 cGy. RESULTS All patient were observed during hospitalization and long term follow-up (from 4 to 21 months). Diffuse and proliferative in stent restenosis (22.02 +/- 21.41 mm) was the most common type of lesions which were treated. Procedure success was 100%, and barchytherapy success was 98%. Median time of hospitalization was one day. Frequency of geographical miss was 7.8%. During in hospital period there were no cases of death, myocardial infarction nor need for revascularization. In long term follow-up 2 myocardial infarctions (4%), 1 bypass grafting (2%) and 9 target vessel revascularizations took place. The cumulative survival without event was 76%. Long term follow-up showed that adverse events occurred in the later period of observation, i.e., up to 6 months after brachytherpy. Median event free survival was 246.5 days. CONCLUSIONS Routine intracoronary brachytherapy due to in stent restenosis is safe and characterized by a high percentage of procedure success in long term follow-up.
