The Effect of Platelet Activity, ABCB1 Genetic Polymorphism, and Renal Function on the Development of Ticagrelor-Related Dyspnea in Patients with Acute Coronary Syndrome.

Purpose: The aim of this study was to determine the effect of ABCB1 genetic polymorphism and renal function on the occurrence of ticagrelor-related dyspnea. Patients and Methods: A total of 299 patients with acute with type 1, 2, or 3 myocardial infarction (with and without ST-segment elevation), who underwent coronary angiography and PTCA with stent implantation and were treated with antiplatelet drugs (ticagrelor and aspirin), were enrolled in this prospective study. For all enrolled patient's platelet aggregation (induction with high-sensitivity adenosine diphosphate, ADP HS) testing was performed using a MULTIPLATE® analyzer. Venous blood was also collected for genotyping. Results: Patients experiencing ticagrelor-related dyspnea had lower ADP HS value (ADP HS ≤ 19.5 U; OR = 2.254; P = 0.009), higher creatinine concentration (>90 µmol/l; OR = 3.414; P = 0.019), and lower GFR value (<60 mL/min/1.73 m2; OR = 2.211; P = 0.035). ABCB1 T allele was associated with ticagrelor-related dyspnea (OR = 2.550; P = 0.04). Conclusion: Ticagrelor-related dyspnea was found to be related to low platelet aggregation, increased plasma creatinine concentration, decreased GFR, and ABCB1 T allele. Carriers of the ABCB1 T allele had a higher plasma creatinine concentration that could be associated with an inhibitory effect of ticagrelor on P-glycoprotein function.

Anterior basal left ventricular pseudoaneurysm in a single vessel disease.

INTRODUCTION: Left ventricular pseudoaneurysm is a rare but serious clinicopathologic entity. MATERIALS AND RESULTS: This article describes a case report of 51-year-old man who experienced recurrence of chest pain and dyspnea 4 months later after anterior ST elevation myocardial infarction of first diagonal branch. Anterior basal left ventricular pseudoaneurysm was diagnosed and successful surgical treatment was performed. One year after operation, patient has no cardiovascular events and remains in NYHA class II. CONCLUSION: Cardiac magnetic resonance should be performed, if there is a suspicion of left ventricular pseudoaneurysm from transthoracic echocardiography. Surgery is the treatment of choice in case of left ventricular pseudoaneuryms because untreated lesions carry a significantly high risk of rupture.

Relationships of Whole-Heart Myocardial Mechanics and Cardiac Morphometrics by Transthoracic Echocardiography with Main Prognostic Factors of Heart Failure in Non-Ischemic Dilated Cardiomyopathy.

BACKGROUND: there are many prognostic factors of heart failure (HF) based on their evaluation from imaging, to laboratory tests. In clinical practice, it is crucial to use widely available, cheap, and easy-to-use prognostic factors, such as left ventricular ejection fraction (LVEF), New York Heart Association (NYHA) functional class, 6 min walk test (6MWT), B-type natriuretic peptide (BNP), etc. We sought to evaluate the relationships between whole-heart myocardial mechanics and cardiac morphometrics with the main commonly used prognostic factors of HF in patients with non-ischemic dilated cardiomyopathy (NIDCM). METHODS AND RESULTS: two-dimensional (2D) echocardiography for myocardial mechanics (global longitudinal, radial, and circumferential strains of the left ventricle; right ventricular longitudinal strain; strain values of reservoir, conduit, and contraction function of both atria) and cardiac morphometric (diameters and volumes of both atria and ventricles) parameters were performed, and the HF main traditional prognostic factors were identified. We assessed 109 patients (68.8% male; 49.7 ± 10.5 years) with newly diagnosed NIDCM. Myocardial mechanics and morphometrics were weakly correlated with the patient's age, gender, and smoking (R = 0.2, p < 0.05). Stronger relationships were observed with NYHA class, 6MWT, and BNP (the strongest correlations were with LVEF: R = -0.499, R 0.462, R = -0.461, p < 0.001, respectively). There were moderately strong correlations with LVEF and other whole-heart myocardial mechanics or morphometrics. Moreover, LVEF with global regurgitation volume (GRV) and right ventricle free wall longitudinal strain (RVFWLS) were the most usually detected parameters in multivariate analysis to be associated with changes in HF prognostic factors. CONCLUSIONS: in NIDCM patients, the main prognostic factors of HF are correlated with whole-heart myocardial mechanics and morphometrics. However, LVEF, GRV, and RVFWLS are the most usually found 2D echocardiographic factors associated with changes in HF prognostic factors.

Accuracy of three-dimensional systolic dyssynchrony and sphericity indexes for identifying early left ventricular remodeling after acute myocardial infarction.

OBJECTIVE: Left ventricle (LV) geometry and dyssynchrony are associated with LV remodeling after acute myocardial infarction (AMI). The aim of this prospective study was to assess the diagnostic value of new three-dimensional echocardiography (3DE) parameters [sphericity (SI) and systolic dyssynchrony indexes (SDI)] for the prediction of LV remodeling after AMI and to compare them with two-dimensional echocardiography (2DE) parameters. METHODS: 2DE and 3DE were performed in 75 patients with AMI within 3 days from the onset of MI and 6 months later. LV remodeling was defined as a ≥15% increase in the LV end-diastolic volume (EDV) at follow-up. 3D SI was calculated by dividing EDV by the volume of a sphere whose diameter was derived from the major end-diastolic LV long axis. SDI was considered as a standard deviation of the time from cardiac cycle onset to minimum systolic volume in 16 LV segments. RESULTS: LV remodeling was identified in 34 (45%) patients using the 2DE method and in 22 (29%) patients using the 3DE method. Evaluated 3DE parameters, such as EDV [area under the receiver operating characteristic (ROC) curve (AUC) 0.742, sensitivity 71%, specificity 79%], end-systolic volume (AUC 0.729, sensitivity 69%, specificity 78%), SDI (AUC 0.777, sensitivity 73%, specificity 77%), and SI, had significant prognostic value for LV remodeling. According to the AUC, the highest predictive value had 3D SI (AUC 0.957, sensitivity 90%, specificity 91%). CONCLUSION: 3DE parameters, especially 3D SI and SDI, play important roles in the prediction of LV remodeling after AMI and can be used in clinical practice.

Multidisciplinary approach to rare primary cardiac sarcoma: a case report and review.

BACKGROUND: Undifferentiated pleomorphic sarcoma is a very rare and aggressive type of primary cardiac tumors. Most cardiac sarcomas result in rapid growth and quick death. According to different sources the median survival is typically 6 to 12 months. We are presenting a case of primary cardiac sarcoma with 26 months disease free survival following cytoreductive surgery and chemotherapy. CASE PRESENTATION: A 48-year-old woman with progressing symptoms of dyspnea and palpitations for over 2 months was referred to a cardiologist. With the help of echocardiography and cardiovascular magnetic resonance cardiac sarcoma was suspected. Open biopsy and cytoreductive surgery were performed, complete resection of the tumor was not possible. Histology revealed undifferentiated pleomorphic sarcoma. Seven cycles of chemotherapy with Doxorubicine and Ifosfamide were completed. Cardiovascular magnetic resonance revealed a complete response - only signs of fibrosis without any signs of tumor were visible. Follow ups with echocardiography, cardiovascular magnetic resonance and chest, abdomen and pelvic computed tomography is performed every 3 months. Twenty-six months from initial diagnosis the patient is still free of recurrence of tumor with no compromises of the quality of life. CONCLUSION: Standard chemotherapy together with cytoreductive surgery can have a complete response effect in undifferentiated pleomorphic sarcoma with unusual long-term survival.

Fatty metaplasia quantification and impact on regional myocardial function as assessed by advanced cardiac MR imaging.

OBJECTIVE: This study aimed to investigate the advantages of recently developed cardiac imaging techniques of fat-water separation and feature tracking to characterize better individuals with chronic myocardial infarction (MI). MATERIALS AND METHODS: Twenty patients who had a previous MI underwent CMR imaging. The study protocol included routine cine and late gadolinium enhancement (LGE) technique. In addition, mDixon LGE imaging was performed in every patient. Left ventricular (LV) circumferential (EccLV) and radial (ErrLV) strain were calculated using dedicated software (CMR42, Circle, Calgary, Canada). The extent of global scar was measured in LGE and fat-water separated images to compare conventional and recent CMR imaging techniques. RESULTS: The infarct size derived from conventional LGE and fat-water separated images was similar. However, detection of lipomatous metaplasia was only possible with mDixon imaging. Subjects with fat deposition demonstrated a significantly smaller percentage of fibrosis than those without fat (10.68 ± 5.07% vs. 13.83 ± 6.30%; p = 0.005). There was no significant difference in EccLV or ErrLV between myocardial segments containing fibrosis only and fibrosis with fat. However, EccLV and ErrLV values were significantly higher in myocardial segments adjacent to fibrosis with fat deposition than in those adjacent to LGE only. CONCLUSIONS: Advanced CMR imaging ensures more detailed tissue characterization in patients with chronic MI without a relevant increase in imaging and post-processing time. Fatty metaplasia may influence regional myocardial deformation especially in the myocardial segments adjacent to scar tissue. A simplified and shortened myocardial viability CMR protocol might be useful to better characterize and stratify patients with chronic MI.

Association of the genetic and traditional risk factors of ischaemic heart disease with STEMI and NSTEMI development.

INTRODUCTION: To evaluate the influence of traditional risk factors of ischaemic heart disease and genetic factors to predict different types of acute coronary syndromes. MATERIALS AND METHODS: Five hundred and twenty-three patients with acute coronary syndromes (393 with ST elevation myocardial infarction (STEMI) and 130 with non-ST elevation myocardial infarction (NSTEMI)) comprised the study group. The control group consisted of 645 subjects free from symptoms of ischaemic heart disease and stroke. Genetic polymorphisms of MMP-2 (-735) C/T, MMP-2 (-1306) C/T, MMP-3 (-1171) 5A/6A, MMP-9 (-1562) C/T and ACE I/D were evaluated using polymerase chain reaction. RESULTS: Patients with acute coronary syndromes more often had ID or II genotype than DD genotype of ACE ( P = 0.04) and 5A5A or 5A6A genotype than 6A6A genotype of MMP-3 ( P = 0.02) in comparison to the control group. The genotypes of other matrix metalloproteinase genes did not differ between the groups. 5A5A and 5A6A genotypes of MMP-3 (odds ratio (OR) 1.5; P = 0.021), II and ID genotypes of ACE (OR 1.7; P = 0.006) along with traditional ischaemic heart disease risk factors such as smoking (OR 4.9; P = 0.001), hypertension (OR 2.0; P = 0.001), diabetes mellitus (OR 2.9; P = 0.001) and dyslipidaemia (OR 2.1; P = 0.001) increased the risk of STEMI. However, the polymorphism of MMP-3 5A/6A and ACE I/D was not associated with the occurrence of NSTEMI. CONCLUSIONS: Genetic polymorphisms of MMP-3 5A/6A and ACE I/D along with conventional ischaemic heart disease risk factors increase the risk of the occurrence of STEMI, while having no influence on the pathogenesis of NSTEMI.

The impact of clinical and genetic factors on ticagrelor and clopidogrel antiplatelet therapy.

AIM: To determine clinically significant factors which may alter the effect of dual antiplatelet therapy with aspirin and ticagrelor or clopidogrel in patients who had undergone percutaneous coronary intervention and stent implantation. MATERIALS & METHODS: The study included 378 patients. All the patients had undergone percutaneous coronary intervention and stent implantation. Platelet aggregation and genotyping for CYP2C19 *2 (rs4244285) and CYP4F2 (rs2108622, rs1558139, rs3093135 and rs2074902) was performed. RESULTS: Significantly lower platelet aggregation values (%agr) were detected in ticagrelor users who carried CYP4F2 rs3093135 TT variant (14.67 ± 5.07%agr) versus AA (22.88 ± 6.30%agr), p = 0.0004, or AT (20.56 ± 6.51%agr), p = 0.0126. CONCLUSION: Results of the current study showed that CYP4F2 rs3093135 TT variant carriers had a higher antiplatelet effect of ticagrelor, and more frequently had nonprocedural bleeding during ticagrelor therapy, as compared with AA and AT variant carriers.

Effect of clinical factors and gene polymorphism of CYP2C19*2, *17 and CYP4F2*3 on early stent thrombosis.

AIM: To determine the main clinical and genetic factors having impact on early coronary stent thrombosis. MATERIALS & METHODS: Genotyping of CYP2C19*2, *17 and CYP4F2*3 in patients with (n = 31) and without stent thrombosis (n = 456) was performed. Clinical and genetic data were analyzed by binary logistic regression. RESULTS: Smoking (OR: 0.317; 95% CI: 0.131-0.767), high-density lipoprotein level in mmol/l (OR: 0.142; 95% CI: 0.040-0.506), CYP2C19*2*2 versus *1*1 and *1*2 genotype (OR: 11.625; 95% CI: 3.498-38.633), CYP4F2 AA versus GA and GG genotype (OR: 3.532; 95% CI: 1.153-10.822) were associated with early stent thrombosis. CONCLUSION: For the first time we have identified a clinically important polymorphism (CYP4F2 G1347A) that was independently associated with early stent thrombosis.

Association of major cardiovascular risk factors with the development of acute coronary syndrome in Lithuania.

Cardiovascular (CV) disease remains the leading cause of death in Lithuania. Timely recognition of CV risk factors and intervention to reduce these risk factors is of absolute importance to prevent coronary heart disease and reduce its burden on society. This study aimed to compare the prevalence of major CV risk factors in general population and acute coronary syndrome (ACS) patients and to determine their association with the development of ACS. Five hundred and twenty-three ACS patients and 645 age- and gender-matched control subjects were enrolled in the study. Smoking, dyslipidaemia, diabetes, and hypertension, but not overweight or obesity, were significantly more prevalent in the ACS patients, compared with control group. The prevalence of smoking, overweight or obesity, and dyslipidaemia were significantly higher in younger patients. Hypertension was highly prevalent in all age subgroups. More than a half of all patients aged <45 years had three or four CV risk factors. Smoking [odds ratio (OR), 7.03, P < 0.0001], hypertension (OR, 1.82; P = 0.001), dyslipidaemia (OR, 1.99; P < 0.0001), and diabetes (OR, 2.30; P < 0.001) were significantly associated with ACS. Significant association of traditional CV risk factors, such as smoking, dyslipidaemia, hypertension, and diabetes with ACS, and high prevalence of these risk factors, especially in younger individuals, calls for attention, and implementation of prevention programmes to reduce the burden of CV morbidity and mortality in Lithuania.

Implementation of international transtelephonic ECG platform for patients with ischemic heart disease.

Ischemic heart disease in European countries over decades causes up to 55% of all cases of sudden death and also has a high rate of mortality, morbidity, and hospital admission. Patients with such chronic diseases also require intensive home care facilities from community nurses. The aim was to establish international multilingual platform for transtelephonic ECG system as an alternative solution for home care and assess its performance. METHODS. During this pilot study, the international toll-free line between Lithuania and Germany was established, and practical applicability of the tele-ECG device was tested. Transtelephonic ECG system was implemented between Telemedicine Center in Bad Segeberg (Bad Segeberg Clinic, Germany), the Call Center in Kaunas at the Hospital of Kaunas University of Medicine, and a patient residence. RESULTS. Over a 6-month follow-up period, 34 patients were recruited. Following the ECG transmission, 86 teleconsultations were done. During the study, a total of 329 ECGs were sent by the patients; out of them, 14 ECGs were with clinical changes. Technical problems due to insufficient patient training, telecommunication systems, acoustic data transmission, and device itself were reported. Up to 23% of ECGs sent by patients were unreadable and not applicable for further clinical analysis. CONCLUSIONS. Our study showed the potential of telemedicine facilities to overcome the problems of access that makes the technique so potentially useful, but for telemonitoring application at patient homes in a wider population, it needs to be improved in terms of technical performance, transmission and analysis automatization.

Left ventricular remodeling following ischemic mitral valve repair: predictive factors.

OBJECTIVES: Annuloplasty is the most common surgical procedure for ischemic mitral regurgitation (MR) that improves symptoms but is also subjected to high incidence of recurrent MR. One of the reasons of recurrent MR could be further left ventricular (LV) remodeling. DESIGN: The study population consisted of 195 patients with ischemic MR. Mitral valve repair and bypass surgery was performed between 2000 and 2006. RESULTS: LV end diastolic diameter (LVEDD) increased in 30.3% of patients in one year following mitral repair. Multivariate ANOVA analysis revealed that if LVEDD index (LVEDDi) before surgery is less than 25 mm/m(2), the probability for LVEDDi to diminish or to stay at the same range is 84.6% higher, than in the case of preoperative LVEDDi >or=25 mm/m(2) and other predictive variables. CONCLUSIONS: Predictive factors for further LV remodeling after ischemic mitral repair 1 year after surgery are preoperative LVEDDi, preoperative LV end systolic diameter index, tricuspid regurgitation grade before surgery, and early postoperative MR grade.

[Heart rate and systolic blood pressure response during the early exercise test and cardiovascular mortality after myocardial infarction]. / Kruvio sukelti sirdies susitraukimu daznio bei kraujospudzio svyravimai ir serganciuju miokardo infarktu mirstamumas.

UNLABELLED: Exercise cardiography still remains the cornerstone of noninvasive evaluation of functional status of cardiovascular system and is almost uniformly performed after myocardial infarction. The patients after myocardial infarction can be divided into relative high- and low-risk groups for subsequent cardiac events if all information available on the exercise test is used. OBJECTIVE: The aim of this study was to evaluate the prognostic significance of the shape of heart rate and systolic blood pressure curves (their dynamic characteristics) during the early exercise testing and after it and to design the prognostic system capable to recognize patients with a high risk of coronary death during 2 years after myocardial infarction. MATERIAL AND METHODS: The submaximal exercise testing within 3 weeks of acute myocardial infarction was performed on 894 patients. Cases of noncardiac deaths or patients subjected to coronary bypass surgery were excluded from the further analysis. At the end of 2 years after myocardial infarction, there were 426 survivors and 42 cases of cardiac death. At 2-year follow-up after infarction in the nonsurvivor group, there were only 42.2% of patients with exercise-induced ST segment depression. This shows that prognostic importance of ST depression is insufficient and demands research of more consistent signs. RESULTS: The cardiovascular response to exercise was interpreted as transiting process of self-regulation of cardiovascular system, and the new predictive signs were found based on the curves of heart rate and systolic blood pressure during the exercise and after it. The prognostic value of these signs was established. The combined use of both the new predictive signs and usual data of early exercise test shows the high predictive possibility of test - the early cardiac death was predicted in 80% of cases. CONCLUSION: The combined use of both, the widely accepted data of early exercise test after myocardial infarction and dynamic characteristics of heart rate and systolic blood pressure, increased the predictive power of the test.

The impact of unrepaired versus repaired mitral regurgitation on functional status of patients with ischemic cardiomyopathy at one year after coronary artery bypass grafting.

BACKGROUND AND AIM OF THE STUDY: The issues regarding the appropriate management of patients with ischemic mitral regurgitation (MR) and advanced left ventricular (LV) dysfunction are controversial and limited. The present study was undertaken to evaluate the mid-term dynamics of MR, LV dimensions, function and NYHA functional class in patients with ischemic cardiomyopathy (ICM) and MR who underwent coronary artery bypass grafting (CABG) either alone or combined with mitral valve (MV) repair. METHODS: A total of 199 patients with LV ejection fraction (LVEF) <35% were included in the study. Of these patients, 73 had MR grade 2+ (group 1), 66 had 0 or 1+ MR (group 2) and underwent isolated CABG, and 60 had MR > 2+ and underwent CABG with MV repair (group 3). RESULTS: At one year after surgery, the severity of MR was unchanged from preoperative grade in group 1 (2.1 +/- 0.5 vs. 1.97 +/- 0.8), and increased in group (0.76 +/- 0.43 vs. 1.44 +/- 0.77; p < 0.05), but was significantly lower in group (2.8 +/- 0.5 vs. 1.6 +/- 0.7; p <0.05). In group 1, the LV end-systolic volume index (LVESVI) tended to increase, the LV end-diastolic volume index (LVEDVI) increased from 69.6 +/- 22.6 to 79.6 +/- 23.2 ml/m2 with an increase in LVEF (from 27.9 +/- 5.9 to 31.3 +/- 9.4%), and pulmonary artery pressure (PAP) increased from 31.9 +/- 7.0 to 39.5 +/- 17.4 mmHg. In group 2, the LV volumes tended to increase, LVEF increased from 30. 3 +/- 4.1 to 34.9 +/- 9.1%, and PAP remained unchanged. In group 3, the LVESVI decreased from 55.4 +/- 16.9 to 47.1 +/- 21.7 ml/m2, LVED-VI tended to decrease, LVEF increased from 31.4 +/- 8.6 to 36.5 +/- 11.3%, and PAP decreased from 35.5 +/- 6.0 to 32.8 +/- 8.3 mmHg. CONCLUSION: Isolated CABG in patients with ICM had no favorable effect on MR reduction, and did not prevent its development. MR grade 2+ in patients with ICM at one year after isolated CABG had a deleterious effect on LV functional status, with progression of LV dilatation and increased PAP. A significant reduction or elimination of MR after combined surgery had a marked positive impact on reverse LV remodeling, including regression of LV dilatation, an increased LVEF, and decreased PAP.

Treatment decisions in stable coronary artery disease: insights from the Euro Heart Survey on Coronary Revascularization.

OBJECTIVE: We sought to assess determinants of clinical decision making in patients with stable coronary artery disease. METHODS: The 2936 patients with stable angina pectoris who enrolled in the Euro Heart Survey on Coronary Revascularization were the subject of this analysis. After the diagnosis has been confirmed, physicians decided on treatment: medical management or revascularization therapy by means of percutaneous coronary intervention or coronary bypass surgery. We applied logistic regression analyses to evaluate the relation between baseline characteristics and treatment decision: medical treatment versus percutaneous coronary intervention, medical treatment versus coronary bypass surgery, and percutaneous coronary intervention versus coronary bypass surgery. RESULTS: The median age was 64 years, 77% were men, and 20% had diabetes. Medical therapy was intended in 690 (24%) patients, percutaneous coronary intervention in 1503 (51%) patients, and coronary bypass surgery in the remaining 743 (25%) patients, respectively. Revascularization was generally preferred in patients with more severe anginal complaints, an intermediate-to-large area of myocardium at risk, and preserved left ventricular function who had not undergone prior coronary revascularization, provided lesions were suitable for treatment. Coronary bypass surgery was preferred over percutaneous coronary intervention in multivessel or left main disease, as well as in those with concomitant valvular heart disease, provided a sufficient number of lesions were suitable for coronary bypass surgery. In those with previous coronary bypass surgeries, more often percutaneous coronary intervention was preferred than redo coronary bypass surgery. Diabetes was not associated with more frequent preference for coronary bypass surgery. CONCLUSIONS: In the hospitals that participated in the Euro Heart Survey on Coronary Revascularization, treatment decisions in stable coronary artery disease were largely in agreement with professional guidelines and determined by multiple factors. Most important deviations between guideline recommendations and clinical practice were seen in patients with extensive coronary disease, impaired left ventricular function, and diabetes.

Ischemic mitral valve repair: correlations between the mechanisms of mitral regurgitation and left ventricular function prior to and following surgery.

OBJECTIVE: To define the mechanisms of ischemic mitral regurgitation (MR) and its correlation with left ventricular (LV) function prior to and 1 year following mitral valve (MV) repair. DESIGN: Fifty-three patients (pts) underwent echocardiographic evaluation of the MR mechanism according to Carpentier's classification; quantification of MR and LV function. RESULTS: Forty-one, 5% of pts had Type I (annulus dilation), 20, 5% had Type II (commissural prolapse) and 38% had Type IIIb MR (predominant posterior leaflet restriction). Preoperative LV function was slightly better preserved in pts with Type II and IIIb MR. Despite similar MV repair efficiency intraoperatively, after 1 year Type I MR progressed vs the remaining types. LV function, including dimensions, ejection fraction and pulmonary artery pressure had a tendency to worsen in pts with Type I and markedly improved in Type II and IIIb MR. CONCLUSIONS: Ischemic MR of Type I is associated with more marked LV dysfunction preoperatively, its further deterioration and MR progression after MV repair. Type II and IIIb MR correlates with better preserved LV function preoperatively and its incremental improvement late after surgery.

[Treatment of patients with ischemic heart disease and diabetes]. / Ligoniu, serganciu isemine sirdies liga ir cukriniu diabetu, gydymo ypatybes.

Around one third of patients with myocardial infarction are diabetic. More vigorous control of hyperglycemia, hyperlipidemia, and hypertension is likely to be of crucial importance for risk reduction. Although the effect of intensive glycemic control appears to be only minor in terms of prevention of cardiac events in diabetic patients, it has a major beneficial impact during acute myocardial infarction and after percutaneous transluminal coronary angioplasty. Lipid-lowering treatment is as effective in diabetic patients with coronary artery disease as in nondiabetic patients. In patients with coronary artery disease, there is strong evidence in favor of the use of b-blockers soon after myocardial infarction as well as in the long term. The metabolic treatment may also be considered as a rational approach for patients with stable angina. The long-term angiotensin converting enzyme inhibitor trials in patients with left ventricle dysfunction soon after myocardial infarction demonstrated a substantial benefit in the subgroup of diabetic patients. Current evidence leads us to recommend revascularization surgery as the first choice in diabetic patients. The management of risk factors should be more intensive in diabetic patients. In diabetic patients with coronary artery disease, most of the medical strategies are as effective as in nondiabetic patients.

[Low density lipoprotein apheresis]. / Mazo tankio lipoproteinu afereze.

Increased blood cholesterol concentration is one of the main factors in ischemic heart disease, development of which is determined by atherosclerotic changes in coronary vessels. Diet and treatment with 3-hydroxi-3-metilglutaril coenzyme A (HMG-CoA) reductase inhibitors helps to reduce low density lipoprotein cholesterol (LDL-Ch) blood concentration up to recommended level of 3.0 mmol/l in most patients but in some patients particularly with familial dyslipidemias cholesterol concentration remains increased even after treatment with maximal doses of lipid-regulating agents or their combinations. The most frequently used mechanical methods of cholesterol removal from blood include the procedures of extracorporeal apheresis. Low density lipoprotein (LDL) apheresis not only significantly reduces the blood concentrations of total cholesterol (TCh), and LDL-Ch, lipoprotein (a) (Lp(a) and fibrinogen but also stops the progression of atherosclerosis in coronary vessels.
